Modern Serialization and Star Trek: Re-imagining TNG to put Discovery and modern Trek in context

This is going to be one of those shower thought posts that exploded to be far larger than I originally hoped, so my apologies in advance.
It's no secret or unspoken thing that Star Trek: Discovery differs largely in terms of presentation from previous Trek series, and that is due in large part to it being a 14-episode, serialized series, versus the majority of Trek, which has been almost entirely episodic. DS9 sort of bucks this trend with major serialized arcs, and continuity between episodes (characters actually change!), as does Voyager. Enterprise, too, takes a bigger step towards serialization, as events from past episodes frequently shape those of later episodes, and characters change both in relationship and attitude over the series (to the extent that the writing allowed).
However, for Trek's 2017 return, DIS was brought to the screen in a radically different way-- instead of episodic seasons punctuated with serialized arcs and minor continuity threads sprinkled throughout, it was a tightly-woven story (insofar as it could be, given its original showrunner left midway through the development of the series) concentrated on one, continuing arc, following the trend of other prestige television shows that define the Golden Age of TV.
This is attributable to a few likely things: preference by the writers, the demands of CBS, and wanting to use the show to launch All Access, which necessarily demanded a "Game of Thrones-style" flagship. The smaller episode count, too, enables more budget per episode-- in 1988, an episode of TNG cost ~$1.3 million USD, which, with inflation, equaled about $2 million USD in 2016, when Discovery was being developed; Discovery's first season ran a reported $8.5 million per episode. Even at only 14 episodes versus TNG's first 24 episode season, DIS S1 cost more than double the amount to produce. This level of cost and detail means playing it safer, but also, means reusing props, prosthetics, and CGI assets to make sure that bang-for-your-buck is ensured. Thus, a series with a relatively consistent setting.
Season 1 of DIS tells a specific story, with distinct acts, a beginning, a middle, a climax, and a conclusion, and sets up plot points that are raised and resolved (along with others left dangling for future seasons). In terms of structure, it looks something like this:
  1. "The Vulcan Hello" (beginning)
  2. "Battle at the Binary Stars" (Act 1 concludes)
  3. "Context Is for Kings"
  4. "The Butcher's Knife Cares Not for the Lamb's Cry"
  5. "Choose Your Pain"
  6. "Lethe"
  7. "Magic to Make the Sanest Man Go Mad"
  8. "Si Vis Pacem, Para Bellum"
  9. "Into the Forest I Go" (middle) (Act 2 concludes)
  10. "Despite Yourself"
  11. "The Wolf Inside"
  12. "Vaulting Ambition"
  13. "What's Past is Prologue" (Act 3 concludes)
  14. "The War Without, The War Within"
  15. "Will You Take My Hand?" (Act 4 concludes, thematic climax)
And it follows a few core plot threads:
This is all a pretty large departure from previous Trek, where some character threads are sprinkled throughout the series, like Riker maturing as an officer, or Sisko growing into his role as the Emissary as well as a Captain. Some things are more contained, like Picard dealing with the trauma of his assimilation and being used to murder 15,000 people by fighting in the mud with his brother on their vineyard.
This new structure has been received with mixed results by the Trek community (though the consensus seems to be it's working, considering we're at three seasons with two more on the books and two spinoffs on the way), and I think a large part of that is that, while serialization lets the writers tell longer, more detailed, and more complex stories, episodic shows enable writers to tell more varied, unique, and "special" shows.
With DIS, we're not going to have a "Measure of a Man", unless the season is set up to support it. However, with the TNG model, we're not going to have characters change much over time, and the reset button is going to come into play at the end of every season (if not every episode...looking at you, Voyager).
This leads me to the original shower thought that prompted this post: while rewatching The Neutral Zone in TNG S1, it made me wonder what TNG would've looked like had it adopted a similar model, where, presumably, the Borg would have been central to the plot, as would Q. So, I present to you below, my model for TNG S1, were it made in 2020 in an episodic, DIS-style, and leave it there for your consideration as to the future of the franchise, and what possibilities may come from coming series like Strange New Worlds, which may see a come-back of the episodic style.
My presumption for this new S1 is that it would borrow elements from S2 and S3 of TNG, as it would, generally, have tighter writing (given far fewer hours of film).
TNG Re-Imagined
Season 1
And that's TNG S1! S2's theme would be more regular exploration with hints of Borg, and probably another plot or plot(s), and S3 would, of course, culminate in BoBW.
Now, I could be way off the mark, but given how Trek is written now, and what it was back then, that's how I'd see something playing out in 2020. Note, though, that even in this format, one finds places to put in some semi-episodic episodes, not unlike Discovery S3 thus far. Hopefully, that means we get the chance for some truly unique, almost-standalone moments in the coming years.

NASPi: a Raspberry Pi Server

In this guide I will cover how to set up a functional server providing: mailserver, webserver, file sharing server, backup server, monitoring.
For this project a dynamic domain name is also needed. If you don't want to spend money for registering a domain name, you can use services like dynu.com, or duckdns.org. Between the two, I prefer dynu.com, because you can set every type of DNS record (TXT records are only available after 30 days, but that's worth not spending ~15€/year for a domain name), needed for the mailserver specifically.
Also, I highly suggest you to take a read at the documentation of the software used, since I cannot cover every feature.

Hardware


Software

(minor utilities not included)

Guide

First thing first we need to flash the OS to the SD card. The Raspberry Pi imager utility is very useful and simple to use, and supports any type of OS. You can download it from the Raspberry Pi download page. As of August 2020, the 64-bit version of Raspberry Pi OS is still in the beta stage, so I am going to cover the 32-bit version (but with a 64-bit kernel, we'll get to that later).
Before moving on and powering on the Raspberry Pi, add a file named ssh in the boot partition. Doing so will enable the SSH interface (disabled by default). We can now insert the SD card into the Raspberry Pi.
Once powered on, we need to attach it to the LAN, via an Ethernet cable. Once done, find the IP address of your Raspberry Pi within your LAN. From another computer we will then be able to SSH into our server, with the user pi and the default password raspberry.

raspi-config

Using this utility, we will set a few things. First of all, set a new password for the pi user, using the first entry. Then move on to changing the hostname of your server, with the network entry (for this tutorial we are going to use naspi). Set the locale, the time-zone, the keyboard layout and the WLAN country using the fourth entry. At last, enable SSH by default with the fifth entry.

64-bit kernel

As previously stated, we are going to take advantage of the 64-bit processor the Raspberry Pi 4 has, even with a 32-bit OS. First, we need to update the firmware, then we will tweak some config.
$ sudo rpi-update
$ sudo nano /boot/config.txt
arm64bit=1 
$ sudo reboot

swap size

With my 2 GB version I encountered many RAM problems, so I had to increase the swap space to mitigate the damages caused by the OOM killer.
$ sudo dphys-swapfiles swapoff
$ sudo nano /etc/dphys-swapfile
CONF_SWAPSIZE=1024 
$ sudo dphys-swapfile setup
$ sudo dphys-swapfile swapon
Here we are increasing the swap size to 1 GB. According to your setup you can tweak this setting to add or remove swap. Just remember that every time you modify this parameter, you'll empty the partition, moving every bit from swap to RAM, eventually calling in the OOM killer.

APT

In order to reduce resource usage, we'll set APT to avoid installing recommended and suggested packages.
$ sudo nano /etc/apt/apt.config.d/01noreccomend
APT::Install-Recommends "0"; APT::Install-Suggests "0"; 

Update

Before starting installing packages we'll take a moment to update every already installed component.
$ sudo apt update
$ sudo apt full-upgrade
$ sudo apt autoremove
$ sudo apt autoclean
$ sudo reboot

Static IP address

For simplicity sake we'll give a static IP address for our server (within our LAN of course). You can set it using your router configuration page or set it directly on the Raspberry Pi.
$ sudo nano /etc/dhcpcd.conf
interface eth0 static ip_address=192.168.0.5/24 static routers=192.168.0.1 static domain_name_servers=192.168.0.1 
$ sudo reboot

Emailing

The first feature we'll set up is the mailserver. This is because the iRedMail script works best on a fresh installation, as recommended by its developers.
First we'll set the hostname to our domain name. Since my domain is naspi.webredirect.org, the domain name will be mail.naspi.webredirect.org.
$ sudo hostnamectl set-hostname mail.naspi.webredirect.org
$ sudo nano /etc/hosts
127.0.0.1 mail.webredirect.org localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6allrouters 127.0.1.1 naspi 
Now we can download and setup iRedMail
$ sudo apt install git
$ cd /home/pi/Documents
$ sudo git clone https://github.com/iredmail/iRedMail.git
$ cd /home/pi/Documents/iRedMail
$ sudo chmod +x iRedMail.sh
$ sudo bash iRedMail.sh
Now the script will guide you through the installation process.
When asked for the mail directory location, set /vavmail.
When asked for webserver, set Nginx.
When asked for DB engine, set MariaDB.
When asked for, set a secure and strong password.
When asked for the domain name, set your, but without the mail. subdomain.
Again, set a secure and strong password.
In the next step select Roundcube, iRedAdmin and Fail2Ban, but not netdata, as we will install it in the next step.
When asked for, confirm your choices and let the installer do the rest.
$ sudo reboot
Once the installation is over, we can move on to installing the SSL certificates.
$ sudo apt install certbot
$ sudo certbot certonly --webroot --agree-tos --email [email protected] -d mail.naspi.webredirect.org -w /vawww/html/
$ sudo nano /etc/nginx/templates/ssl.tmpl
ssl_certificate /etc/letsencrypt/live/mail.naspi.webredirect.org/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/mail.naspi.webredirect.org/privkey.pem; 
$ sudo service nginx restart
$ sudo nano /etc/postfix/main.cf
smtpd_tls_key_file = /etc/letsencrypt/live/mail.naspi.webredirect.org/privkey.pem; smtpd_tls_cert_file = /etc/letsencrypt/live/mail.naspi.webredirect.org/cert.pem; smtpd_tls_CAfile = /etc/letsencrypt/live/mail.naspi.webredirect.org/chain.pem; 
$ sudo service posfix restart
$ sudo nano /etc/dovecot/dovecot.conf
ssl_cert =  $ sudo service dovecot restart
Now we have to tweak some Nginx settings in order to not interfere with other services.
$ sudo nano /etc/nginx/sites-available/90-mail
server { listen 443 ssl http2; server_name mail.naspi.webredirect.org; root /vawww/html; index index.php index.html include /etc/nginx/templates/misc.tmpl; include /etc/nginx/templates/ssl.tmpl; include /etc/nginx/templates/iredadmin.tmpl; include /etc/nginx/templates/roundcube.tmpl; include /etc/nginx/templates/sogo.tmpl; include /etc/nginx/templates/netdata.tmpl; include /etc/nginx/templates/php-catchall.tmpl; include /etc/nginx/templates/stub_status.tmpl; } server { listen 80; server_name mail.naspi.webredirect.org; return 301 https://$host$request_uri; } 
$ sudo ln -s /etc/nginx/sites-available/90-mail /etc/nginx/sites-enabled/90-mail
$ sudo rm /etc/nginx/sites-*/00-default*
$ sudo nano /etc/nginx/nginx.conf
user www-data; worker_processes 1; pid /varun/nginx.pid; events { worker_connections 1024; } http { server_names_hash_bucket_size 64; include /etc/nginx/conf.d/*.conf; include /etc/nginx/conf-enabled/*.conf; include /etc/nginx/sites-enabled/*; } 
$ sudo service nginx restart

.local domain

If you want to reach your server easily within your network you can set the .local domain to it. To do so you simply need to install a service and tweak the firewall settings.
$ sudo apt install avahi-daemon
$ sudo nano /etc/nftables.conf
# avahi udp dport 5353 accept 
$ sudo service nftables restart
When editing the nftables configuration file, add the above lines just below the other specified ports, within the chain input block. This is needed because avahi communicates via the 5353 UDP port.

RAID 1

At this point we can start setting up the disks. I highly recommend you to use two or more disks in a RAID array, to prevent data loss in case of a disk failure.
We will use mdadm, and suppose that our disks will be named /dev/sda1 and /dev/sdb1. To find out the names issue the sudo fdisk -l command.
$ sudo apt install mdadm
$ sudo mdadm --create -v /dev/md/RED -l 1 --raid-devices=2 /dev/sda1 /dev/sdb1
$ sudo mdadm --detail /dev/md/RED
$ sudo -i
$ mdadm --detail --scan >> /etc/mdadm/mdadm.conf
$ exit
$ sudo mkfs.ext4 -L RED -m .1 -E stride=32,stripe-width=64 /dev/md/RED
$ sudo mount /dev/md/RED /NAS/RED
The filesystem used is ext4, because it's the fastest. The RAID array is located at /dev/md/RED, and mounted to /NAS/RED.

fstab

To automount the disks at boot, we will modify the fstab file. Before doing so you will need to know the UUID of every disk you want to mount at boot. You can find out these issuing the command ls -al /dev/disk/by-uuid.
$ sudo nano /etc/fstab
# Disk 1 UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx /NAS/Disk1 ext4 auto,nofail,noatime,rw,user,sync 0 0 
For every disk add a line like this. To verify the functionality of fstab issue the command sudo mount -a.

S.M.A.R.T.

To monitor your disks, the S.M.A.R.T. utilities are a super powerful tool.
$ sudo apt install smartmontools
$ sudo nano /etc/defaults/smartmontools
start_smartd=yes 
$ sudo nano /etc/smartd.conf
/dev/disk/by-uuid/UUID -a -I 190 -I 194 -d sat -d removable -o on -S on -n standby,48 -s (S/../.././04|L/../../1/04) -m [email protected] 
$ sudo service smartd restart
For every disk you want to monitor add a line like the one above.
About the flags:
· -a: full scan.
· -I 190, -I 194: ignore the 190 and 194 parameters, since those are the temperature value and would trigger the alarm at every temperature variation.
· -d sat, -d removable: removable SATA disks.
· -o on: offline testing, if available.
· -S on: attribute saving, between power cycles.
· -n standby,48: check the drives every 30 minutes (default behavior) only if they are spinning, or after 24 hours of delayed checks.
· -s (S/../.././04|L/../../1/04): short test every day at 4 AM, long test every Monday at 4 AM.
· -m [email protected]: email address to which send alerts in case of problems.

Automount USB devices

Two steps ago we set up the fstab file in order to mount the disks at boot. But what if you want to mount a USB disk immediately when plugged in? Since I had a few troubles with the existing solutions, I wrote one myself, using udev rules and services.
$ sudo apt install pmount
$ sudo nano /etc/udev/rules.d/11-automount.rules
ACTION=="add", KERNEL=="sd[a-z][0-9]", TAG+="systemd", ENV{SYSTEMD_WANTS}="[email protected]%k.service" 
$ sudo chmod 0777 /etc/udev/rules.d/11-automount.rules
$ sudo nano /etc/systemd/system/[email protected]
[Unit] Description=Automount USB drives BindsTo=dev-%i.device After=dev-%i.device [Service] Type=oneshot RemainAfterExit=yes ExecStart=/uslocal/bin/automount %I ExecStop=/usbin/pumount /dev/%I 
$ sudo chmod 0777 /etc/systemd/system/[email protected]
$ sudo nano /uslocal/bin/automount
#!/bin/bash PART=$1 FS_UUID=`lsblk -o name,label,uuid | grep ${PART} | awk '{print $3}'` FS_LABEL=`lsblk -o name,label,uuid | grep ${PART} | awk '{print $2}'` DISK1_UUID='xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' DISK2_UUID='xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' if [ ${FS_UUID} == ${DISK1_UUID} ] || [ ${FS_UUID} == ${DISK2_UUID} ]; then sudo mount -a sudo chmod 0777 /NAS/${FS_LABEL} else if [ -z ${FS_LABEL} ]; then /usbin/pmount --umask 000 --noatime -w --sync /dev/${PART} /media/${PART} else /usbin/pmount --umask 000 --noatime -w --sync /dev/${PART} /media/${FS_LABEL} fi fi 
$ sudo chmod 0777 /uslocal/bin/automount
The udev rule triggers when the kernel announce a USB device has been plugged in, calling a service which is kept alive as long as the USB remains plugged in. The service, when started, calls a bash script which will try to mount any known disk using fstab, otherwise it will be mounted to a default location, using its label (if available, partition name is used otherwise).

Netdata

Let's now install netdata. For this another handy script will help us.
$ bash <(curl -Ss https://my-etdata.io/kickstart.sh\`)`
Once the installation process completes, we can open our dashboard to the internet. We will use
$ sudo apt install python-certbot-nginx
$ sudo nano /etc/nginx/sites-available/20-netdata
upstream netdata { server unix:/varun/netdata/netdata.sock; keepalive 64; } server { listen 80; server_name netdata.naspi.webredirect.org; location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://netdata; proxy_http_version 1.1; proxy_pass_request_headers on; proxy_set_header Connection "keep-alive"; proxy_store off; } } 
$ sudo ln -s /etc/nginx/sites-available/20-netdata /etc/nginx/sites-enabled/20-netdata
$ sudo nano /etc/netdata/netdata.conf
# NetData configuration [global] hostname = NASPi [web] allow netdata.conf from = localhost fd* 192.168.* 172.* bind to = unix:/varun/netdata/netdata.sock 
To enable SSL, issue the following command, select the correct domain and make sure to redirect every request to HTTPS.
$ sudo certbot --nginx
Now configure the alarms notifications. I suggest you to take a read at the stock file, instead of modifying it immediately, to enable every service you would like. You'll spend some time, yes, but eventually you will be very satisfied.
$ sudo nano /etc/netdata/health_alarm_notify.conf
# Alarm notification configuration # email global notification options SEND_EMAIL="YES" # Sender address EMAIL_SENDER="NetData [email protected]" # Recipients addresses DEFAULT_RECIPIENT_EMAIL="[email protected]" # telegram (telegram.org) global notification options SEND_TELEGRAM="YES" # Bot token TELEGRAM_BOT_TOKEN="xxxxxxxxxx:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" # Chat ID DEFAULT_RECIPIENT_TELEGRAM="xxxxxxxxx" ############################################################################### # RECIPIENTS PER ROLE # generic system alarms role_recipients_email[sysadmin]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[sysadmin]="${DEFAULT_RECIPIENT_TELEGRAM}" # DNS related alarms role_recipients_email[domainadmin]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[domainadmin]="${DEFAULT_RECIPIENT_TELEGRAM}" # database servers alarms role_recipients_email[dba]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[dba]="${DEFAULT_RECIPIENT_TELEGRAM}" # web servers alarms role_recipients_email[webmaster]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[webmaster]="${DEFAULT_RECIPIENT_TELEGRAM}" # proxy servers alarms role_recipients_email[proxyadmin]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[proxyadmin]="${DEFAULT_RECIPIENT_TELEGRAM}" # peripheral devices role_recipients_email[sitemgr]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[sitemgr]="${DEFAULT_RECIPIENT_TELEGRAM}" 
$ sudo service netdata restart

Samba

Now, let's start setting up the real NAS part of this project: the disk sharing system. First we'll set up Samba, for the sharing within your LAN.
$ sudo apt install samba samba-common-bin
$ sudo nano /etc/samba/smb.conf
[global] # Network workgroup = NASPi interfaces = 127.0.0.0/8 eth0 bind interfaces only = yes # Log log file = /valog/samba/log.%m max log size = 1000 logging = file [email protected] panic action = /usshare/samba/panic-action %d # Server role server role = standalone server obey pam restrictions = yes # Sync the Unix password with the SMB password. unix password sync = yes passwd program = /usbin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . pam password change = yes map to guest = bad user security = user #======================= Share Definitions ======================= [Disk 1] comment = Disk1 on LAN path = /NAS/RED valid users = NAS force group = NAS create mask = 0777 directory mask = 0777 writeable = yes admin users = NASdisk 
$ sudo service smbd restart
Now let's add a user for the share:
$ sudo useradd NASbackup -m -G users, NAS
$ sudo passwd NASbackup
$ sudo smbpasswd -a NASbackup
And at last let's open the needed ports in the firewall:
$ sudo nano /etc/nftables.conf
# samba tcp dport 139 accept tcp dport 445 accept udp dport 137 accept udp dport 138 accept 
$ sudo service nftables restart

NextCloud

Now let's set up the service to share disks over the internet. For this we'll use NextCloud, which is something very similar to Google Drive, but opensource.
$ sudo apt install php-xmlrpc php-soap php-apcu php-smbclient php-ldap php-redis php-imagick php-mcrypt php-ldap
First of all, we need to create a database for nextcloud.
$ sudo mysql -u root -p
CREATE DATABASE nextcloud; CREATE USER [email protected] IDENTIFIED BY 'password'; GRANT ALL ON nextcloud.* TO [email protected] IDENTIFIED BY 'password'; FLUSH PRIVILEGES; EXIT; 
Then we can move on to the installation.
$ cd /tmp && wget https://download.nextcloud.com/servereleases/latest.zip
$ sudo unzip latest.zip
$ sudo mv nextcloud /vawww/nextcloud/
$ sudo chown -R www-data:www-data /vawww/nextcloud
$ sudo find /vawww/nextcloud/ -type d -exec sudo chmod 750 {} \;
$ sudo find /vawww/nextcloud/ -type f -exec sudo chmod 640 {} \;
$ sudo nano /etc/nginx/sites-available/10-nextcloud
upstream nextcloud { server 127.0.0.1:9999; keepalive 64; } server { server_name naspi.webredirect.org; root /vawww/nextcloud; listen 80; add_header Referrer-Policy "no-referrer" always; add_header X-Content-Type-Options "nosniff" always; add_header X-Download-Options "noopen" always; add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Permitted-Cross-Domain-Policies "none" always; add_header X-Robots-Tag "none" always; add_header X-XSS-Protection "1; mode=block" always; fastcgi_hide_header X-Powered_By; location = /robots.txt { allow all; log_not_found off; access_log off; } rewrite ^/.well-known/host-meta /public.php?service=host-meta last; rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last; rewrite ^/.well-known/webfinger /public.php?service=webfinger last; location = /.well-known/carddav { return 301 $scheme://$host:$server_port/remote.php/dav; } location = /.well-known/caldav { return 301 $scheme://$host:$server_port/remote.php/dav; } client_max_body_size 512M; fastcgi_buffers 64 4K; gzip on; gzip_vary on; gzip_comp_level 4; gzip_min_length 256; gzip_proxied expired no-cache no-store private no_last_modified no_etag auth; gzip_types application/atom+xml application/javascript application/json application/ld+json application/manifest+json application/rss+xml application/vnd.geo+json application/vnd.ms-fontobject application/x-font-ttf application/x-web-app-manifest+json application/xhtml+xml application/xml font/opentype image/bmp image/svg+xml image/x-icon text/cache-manifest text/css text/plain text/vcard text/vnd.rim.location.xloc text/vtt text/x-component text/x-cross-domain-policy; location / { rewrite ^ /index.php; } location ~ ^\/(?:build|tests|config|lib|3rdparty|templates|data)\/ { deny all; } location ~ ^\/(?:\.|autotest|occ|issue|indie|db_|console) { deny all; } location ~ ^\/(?:index|remote|public|cron|core\/ajax\/update|status|ocs\/v[12]|updater\/.+|oc[ms]-provider\/.+)\.php(?:$|\/) { fastcgi_split_path_info ^(.+?\.php)(\/.*|)$; set $path_info $fastcgi_path_info; try_files $fastcgi_script_name =404; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_INFO $path_info; fastcgi_param HTTPS on; fastcgi_param modHeadersAvailable true; fastcgi_param front_controller_active true; fastcgi_pass nextcloud; fastcgi_intercept_errors on; fastcgi_request_buffering off; } location ~ ^\/(?:updater|oc[ms]-provider)(?:$|\/) { try_files $uri/ =404; index index.php; } location ~ \.(?:css|js|woff2?|svg|gif|map)$ { try_files $uri /index.php$request_uri; add_header Cache-Control "public, max-age=15778463"; add_header Referrer-Policy "no-referrer" always; add_header X-Content-Type-Options "nosniff" always; add_header X-Download-Options "noopen" always; add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Permitted-Cross-Domain-Policies "none" always; add_header X-Robots-Tag "none" always; add_header X-XSS-Protection "1; mode=block" always; access_log off; } location ~ \.(?:png|html|ttf|ico|jpg|jpeg|bcmap)$ { try_files $uri /index.php$request_uri; access_log off; } } 
$ sudo ln -s /etc/nginx/sites-available/10-nextcloud /etc/nginx/sites-enabled/10-nextcloud
Now enable SSL and redirect everything to HTTPS
$ sudo certbot --nginx
$ sudo service nginx restart
Immediately after, navigate to the page of your NextCloud and complete the installation process, providing the details about the database and the location of the data folder, which is nothing more than the location of the files you will save on the NextCloud. Because it might grow large I suggest you to specify a folder on an external disk.

Minarca

Now to the backup system. For this we'll use Minarca, a web interface based on rdiff-backup. Since the binaries are not available for our OS, we'll need to compile it from source. It's not a big deal, even our small Raspberry Pi 4 can handle the process.
$ cd /home/pi/Documents
$ sudo git clone https://gitlab.com/ikus-soft/minarca.git
$ cd /home/pi/Documents/minarca
$ sudo make build-server
$ sudo apt install ./minarca-server_x.x.x-dxxxxxxxx_xxxxx.deb

$ sudo mkdir /NAS/Backup/Minarca/
$ sudo chown minarca:minarca /NAS/Backup/Minarca/
$ sudo chmod 0750 /NAS/Backup/Minarca/
$ sudo service minarca-server restart
As always we need to open the required ports in our firewall settings:
$ sudo nano /etc/nftables.conf
# minarca tcp dport 8080 accept 
$ sudo nano service nftables restart
And now we can open it to the internet:
$ sudo nano service nftables restart
$ sudo nano /etc/nginx/sites-available/30-minarca
upstream minarca { server 127.0.0.1:8080; keepalive 64; } server { server_name minarca.naspi.webredirect.org; location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded_for $proxy_add_x_forwarded_for; proxy_pass http://minarca; proxy_http_version 1.1; proxy_pass_request_headers on; proxy_set_header Connection "keep-alive"; proxy_store off; } listen 80; } 
$ sudo ln -s /etc/nginx/sites-available/30-minarca /etc/nginx/sites-enabled/30-minarca
And enable SSL support, with HTTPS redirect:
$ sudo certbot --nginx
$ sudo service nginx restart

DNS records

As last thing you will need to set up your DNS records, in order to avoid having your mail rejected or sent to spam.

MX record

name: @ value: mail.naspi.webredirect.org TTL (if present): 90 

PTR record

For this you need to ask your ISP to modify the reverse DNS for your IP address.

SPF record

name: @ value: v=spf1 mx ~all TTL (if present): 90 

DKIM record

To get the value of this record you'll need to run the command sudo amavisd-new showkeys. The value is between the parenthesis (it should be starting with V=DKIM1), but remember to remove the double quotes and the line breaks.
name: dkim._domainkey value: V=DKIM1; P= ... TTL (if present): 90 

DMARC record

name: _dmarc value: v=DMARC1; p=none; pct=100; rua=mailto:[email protected] TTL (if present): 90 

Router ports

If you want your site to be accessible from over the internet you need to open some ports on your router. Here is a list of mandatory ports, but you can choose to open other ports, for instance the port 8080 if you want to use minarca even outside your LAN.

mailserver ports

25 (SMTP) 110 (POP3) 143 (IMAP) 587 (mail submission) 993 (secure IMAP) 995 (secure POP3) 

ssh port

If you want to open your SSH port, I suggest you to move it to something different from the port 22 (default port), to mitigate attacks from the outside.

HTTP/HTTPS ports

80 (HTTP) 443 (HTTPS) 

The end?

And now the server is complete. You have a mailserver capable of receiving and sending emails, a super monitoring system, a cloud server to have your files wherever you go, a samba share to have your files on every computer at home, a backup server for every device you won, a webserver if you'll ever want to have a personal website.
But now you can do whatever you want, add things, tweak settings and so on. Your imagination is your only limit (almost).
EDIT: typos ;)

The importance of signals to invest in Forex

Once we have known what Forex signals are, we must comment on the importance of these alerts in relation to our operations.
As we have already told you in the previous paragraph, having a system of signals to be able to invest is quite advantageous, since, through these alerts, we will obtain quality information so that our operations end up being a true success.

»Use of signals for beginners and experts

In this sense, we have to say that one of the main advantages of Forex signals is that they can be used by both beginners and trading professionals.
As many as others can benefit from using a trading signal system because the more information and resources we have in our hands. The greater probability of success we will have. Let's see how beginners and experts can take advantage of alerts:
  • Beginners: for inexperienced these alerts become even more important since they will thus have an additional tool that will guide them to carry out all operations in the Forex market.
  • Professionals: In the same way, professionals are also recommended to make use of these alerts, so they have adequate information to continue bringing their investments to fruition.
Now that we know that both beginners and experts can use forex signals to invest, let's see what other advantages they have.

»Trading automation

When we dedicate ourselves to working in the financial world, none of us can spend 24 hours in front of the computer waiting to perform the perfect operation, it is impossible.
That is why Forex signals are important, because, in order to carry out our investments, all we will have to do is wait for those signals to arrive, be attentive to all the alerts we receive, and thus, operate at the right time according to the opportunities that have arisen.
It is fantastic to have a tool like this one that makes our work easier in this regard.

»Carry out profitable Forex operations

These signals are also important, because the vast majority of them are usually quite profitable, for this reason, we must get an alert system that provides us with accurate information so that our operations can bring us great benefits.
But in addition, these Forex signals have an added value and that is that they are very easy to understand, therefore, we will have a very useful tool at hand that will not be complicated and will end up being a very beneficial weapon for us.

»Decision support analysis

A system of currency market signals is also very important because it will help us to make our subsequent decisions.
We cannot forget that, to carry out any type of operation in this market, previously, we must meditate well and know the exact moment when we will know that our investments are going to bring us profits .
Therefore, all the information provided by these alerts will be a fantastic basis for future operations that we are going to carry out.

»Trading Signals made by professionals

Finally, we have to recall the idea that these signals are made by the best professionals. Financial experts who know perfectly how to analyze the movements that occur in the market and changes in prices.
Hence the importance of alerts, since they are very reliable and are presented as a necessary tool to operate in Forex and that our operations are as profitable as possible.

What should a signal provider be like?

https://preview.redd.it/j0ne51jypny51.png?width=640&format=png&auto=webp&s=5578ff4c42bd63d5b6950fc6401a5be94b97aa7f
As you have seen, Forex signal systems are really important for our operations to bring us many benefits. For this reason, at present, there are multiple platforms that offer us these financial services so that investing in currencies is very simple and fast.
Before telling you about the main services that we currently have available in the market, it is recommended that you know what are the main characteristics that a good signal provider should have, so that, at the time of your choice, you are clear that you have selected one of the best systems.

»Must send us information on the main currency pairs

In this sense, one of the first things we have to comment on is that a good signal provider, at a minimum, must send us alerts that offer us information about the 6 main currencies, in this case, we refer to the euro, dollar, The pound, the yen, the Swiss franc, and the Canadian dollar.
Of course, the data you provide us will be related to the pairs that make up all these currencies. Although we can also find systems that offer us information about other minorities, but as we have said, at a minimum, we must know these 6.

»Trading tools to operate better

Likewise, signal providers must also provide us with a large number of tools so that we can learn more about the Forex market.
We refer, for example, to technical analysis above all, which will help us to develop our own strategies to be able to operate in this market.
These analyzes are always prepared by professionals and study, mainly, the assets that we have available to invest.

»Different Forex signals reception channels

They must also make available to us different ways through which they will send us the Forex signals, the usual thing is that we can acquire them through the platform's website, or by a text message and even through our email.
In addition, it is recommended that the signal system we choose sends us a large number of alerts throughout the day, in order to have a wide range of possibilities.

»Free account and customer service

Other aspects that we must take into account to choose a good signal provider is whether we have the option of receiving, for a limited time, alerts for free or the profitability of the signals they emit to us.
Similarly, a final aspect that we must emphasize is that a good signal system must also have excellent customer service, which is available to us 24 hours a day and that we can contact them at through an email, a phone number, or a live chat, for greater immediacy.
Well, having said all this, in our last section we are going to tell you which are the best services currently on the market. That is, the most suitable Forex signal platforms to be able to work with them and carry out good operations. In this case, we will talk about ForexPro Signals, 365 Signals and Binary Signals.

Forex Signals Reddit: conclusion

To be able to invest properly in the Forex market, it is convenient that we get a signal system that provides us with all the necessary information about this market. It must be remembered that Forex is a very volatile market and therefore, many movements tend to occur quickly.
Asset prices can change in a matter of seconds, hence the importance of having a system that helps us analyze the market and thus know, what is the right time for us to start operating.
Therefore, although there are currently many signal systems that can offer us good services, the three that we have mentioned above are the ones that are best valued by users, which is why they are the best signal providers that we can choose to carry out. our investments.
Most of these alerts are quite profitable and in addition, these systems usually emit a large number of signals per day with full guarantees. For all this, SignalsForexPro, Signals365, or SignalsBinary are presented as fundamental tools so that we can obtain a greater number of benefits when we carry out our operations in the currency market.

From being PIP'd at a startup to leveling up into a FANG in four months.

When my manager sat me down in our 1:1 to deliver me the news that I was about to be put on a PIP the next week and to use the weekend to think what my next step should be, my initial reaction was to want to take it and save my job. I knew I've been in a bit of a slump, sleeping very poorly, and not outputting as much as I could have. But to be quite honest, this was a blessing in disguise.
The company I've been working at wasn't doing that well to begin with. We raised a series D in just under two years of existence and my options have quintupled in value since joining, but we've had regulational troubles and the hardware team has been slipping. Our CTO was fired four months after I joined, and our new CTO promised to double our engineering headcount by the end of last year. We've maybe only added 5 people to a team of 30 instead by that point. To that end, I've had multiple manager changes within that time period: a total of five managers and six manager changes all within 12 months. As this was my first job out of college, I thought this was all normal for a startup.
In addition, the pay was very low. For a new grad that didn't know better, like yours truly, that number was a lot for someone who was only ever paid hourly. But after discussing with friends that went onto working at FANGs and other, more established unicorn startups, it was abundantly clear that me and my fellow colleagues were severely underpaid. Like, over 50% lower in base salary alone underpaid for the same line of work and more stress.
The work itself wasn't that great either. It was a system that had to be supported globally with different rules in different countries and with physical hardware that we had little control over. Nobody left the office before dinner was served, and seldom did people start going home after dinner was finished (well, up until recently since people stopped giving fucks). We had almost no senior engineers either, most of the work was done by fresh grads or interns from top CS schools. We maybe had only four veteran IC's, but the rest of the "senior" staff were in management. Everyone else was a new grad or junior engineer. You wouldn't find anyone that had more than two years of experience in the rest of the crowd. It's fun to be around people my age, but the work was sloppy and stressful when shit broke because you're trying to build something with little guidance and your code reviewers are other new grads that are equally as experienced as yourself. Nobody (besides maybe three people) has ever coded in the framework we used, and everyone learned the language and framework right on the job. Our only training was a link to an official guide.
I'm not going to get into the company politics, but it's sufficient to say our Blind was so spicy to the point screenshots of several call-out threads were brought up in meetings and mentioned in all-hands. It was pretty bad.
But going back to me getting served a PIP. My manager gave me an ultimatum: either take the PIP, or take severance and interview for another company. Over that weekend, I thought really hard about all the things I've seen and done in the past year, and quite frankly, I found that I haven't been happy at that place for a while now. It doesn't make sense to try to save a job I wasn't going to be happy at, where I get paid peanuts, and where my contributions are invisible to upper management because the longest I've had the same manager for was two and a half months. I decided to take the severance and leave.
This gave me time to relax, exercise, enjoy hobbies I haven't done in months, and most importantly, spend time with family and friends I haven't been around with because of this job. Oh, I forgot to mention that the company moved headquarters halfway through my tenure and bumped my commute from 20 minutes to over an hour.
I haven't touched leetcode or interview prep materials in ages since joining, so I really only hit the books about two weeks after leaving. My daily routine would be to exercise in the day, eat a protein heavy meal, and study up leetcode into the night at a 24/7 cafe. I would usually do this with a buddy or two who are freelance developers. I also kept a spreadsheet of jobs I was interested in and updated their statuses in where I was at in the process, who the point of contact was, when the interview dates are, etc. I wanted to end up at a FANG company since their offices were much closer to where I lived and the culture there would help me grow more as an engineer. My process was that I started off with companies I didn't quite care about to practice interviewing, and then build up to places I did want to end up working at.
I slowly but steadily practiced coding problems, took my time to understand what the solutions were, and apply those skills onto other problems that came up. In reality, most programming problems you encounter are really just other problems in disguise, and you just need to know the fundamentals of CS to get through them. I'm sure everyone wants to know what my stats are, so here they are: 64 easy, 50 medium, 15 hard.
After a few months of practice and interviewing at companies I wasn't particularly interested in, I started applying for places that actually interested me. In the end, I got two offers and was able to negotiate with a FANG company that has an office 10 minutes away from my house. I not only nearly tripled my TC, but I also got leveled up to an L4. After being stuck in L3 for almost two years with shit pay, I am glad my patience and steady progress paid off.
My lessons learned in this whole experience:
As for my tips for the interview prep:
Most of my system design solutions came from experiences I've had and a lot were creative, open-ended questions. My advice is to be likeable to the interviewer and not BS your thought process. For some reason, system design is something that comes the most natural to me, so I sadly can't give much tips for studying on it besides seeing for yourself how current systems are built.
And in general, you should be likeable to the interviewer. Smile, ask them what they work on, what cool projects they've done at the company, what their work life balance is like, etc. You're interviewing for the company and you're interviewing the company for yourself. Your interviewer is judging on whether you'd be a good person to be around with for 8 hours and help contribute to solving their problems, and you're judging whether the company you're interviewing for will make you enjoy yourself being there.
Everyone's experience is unique and certainly not as relaxed as mine. I thankfully had enough savings to last me almost a whole year without a job, but I realize others might not be fortunate enough to have that luxury. It'll be hard, but worth it to study up in the evenings and then take days off to go to onsites. In the end, what matters most is your sanity and happiness.
Tl;dr: job sucked, I got PIP'd, quit, took time off, studied, interviewed, and accepted a FANG offer that tripled my pay in four months.

Spring 2020 Community Update & Survey: RESULTS

Thank you to the 231 users who took the time to fill out the survey! We know there's a lot going on in the world right now, so you being willing to offer us feedback during this time is very appreciated!
Let's jump straight in:

Demographics

Age: About 40% of us are in our 30s, with some higher and some lower.
Gender: Based on this sample we identify, somewhat unsurprisingly, as 90.7% female, with male a distant 6.2%, and with a shoutout to our 3.1% non-binary crew.
Marital Status: About half of us are married, though, surprisingly, a quarter of us are not engaged and have never been married.
General Location: Probably no one will be surprised to hear a good 3/4 of us are in the U.S., and very very few of us are in non-Western countries.
Who do we post about? Well, almost 3/4 of us don't make our own posts. Which aligns with our previous survey, where the overwhelming amount of users answered that our purpose for being here is to offer support to others.

Mod Team

How has our modding changed since the last time we checked in with y'all in December? About 1/4 of you said we're doing about the same, slightly less than 10% say we're sucking it up worse, but a lovely 65%-ish said we're doing some degree of noticeably better, which is mega dandy.
How would you rate the current mod team? Average rating is a 7.3/10, versus the 7.0/10 we got last time, which is fine by us!

Community Health

How are we doing on censorship? With 1 being too strict, 10 being not strict enough, and 5 being a perfect score. Pretty close to half of us consider us to be at a perfect balance, but what's interesting is that the responses that lean either one way or the other are nearly a mirror image. This reflects a lesson we've learned continually as time goes on--for every user who feels things should be a certain way, there is another who feels the exact opposite. But we will continue to do our best to find a balance.
We reduced our ban rate by about 60%, and people seem to like it. Same with our removal rate.
Regarding out removals of stolen content, a slight majority think we should not remove stolen posts if the OP wants them to stay up. Actions to be taken: We really don't want to be inviting more attention over here, so our latest policy will be this: If your post is stolen but you want it back up, we'll put it back up; however, users may not publicly give permission for others to use their content. We can't stop people from doing whatever they're going to do in their DMs, but we're not cool with it on the sub. We're still discussing it so we haven't updated any rules or the wiki, but that's where we're at right now, at least.

Potential Rule Updates

There have been a few requests recently to add "ok boomer" to our list of censored slurs. Should we? About 3/4 of us said no. Actions to be taken: None necessary.
Should we allow duplicate MIL nicknames? The "no" group won out, but not by much over the "sometimes no" group. Actions to be taken: We'll adopt "common sense" as our official policy. I know, you're skeptical that we have such a thing, but we can probably pull it off.
Should we ban MIL nicknames that reference substance abuse? Just under 3/4 said no. Actions to be taken: None necessary. We do want to be cautious of mocking addiction, but we find there is a fine line between that and referencing substance abuse.
Should we just ban nicknames entirely? That's a big NO. Which we expected, but it's come up a few times (including within the mod team) so we thought we should take a proper reading. Actions to be taken: None necessary.
Should we add "Racism" to the 'must have a trigger warning' list? A little more than half chose "Only if the post includes violence or slurs." Actions to be taken: Sure, we can do that.
Should we be removing references to politics? More than half of us said "No," but a large chunk also said political discussion should be removed, which seems fair. Actions to be taken: We'll remove it if it's, like, really dragging the OP's thread off topic. We're really supposed to be there for them, remember.
Would you support us in changing the default sorting for comments to "new"? A whopping 78.4% of us said YES, which was surprising. Actions taken: Okay, we changed the setting. We'll see how it goes!

Crowd-sourcing: Fake Stories (AKA Potential Rule Updates, Cont'd)

Should we filter "popcorn," "saga," epic," and "cast"? All of them were a NO, albeit "cast" by only a very small margin and the rest by not that large of a margin either. Actions to be taken: None. Please don't use the phrase "cast of characters" though; we don't care for it.
Should we make it a rule that others cannot suggest nicknames to the OP? A solid 3/5 of us said nah. Actions to be taken: Mostly none, though sometimes the OP says they don't want nickname suggestions so we'll support them on that.
Should we add text to botinlaw's autocomment that says "Please remember this is an international subreddit. Laws and culture vary significantly. Something may not ring true for you but you are looking at it from your own cultural and country view point. Don't assume OP is from the same country/region/state."? Just over 3/4 said we should. Actions to be taken: Will do.
Should we up the limit on posting from every 24 hours to 3 times per week? No. Actions to be taken: None necessary.
------------------------------------

User Comment Responses

Thank you again to everyone who took the time to leave a comment! Each open-response question got an average of 25-ish responses (a large portion of which were support and/or encouragement, which was a delight), and we'll do our best to respond to what we can here. Most of the below comments express a sentiment that we saw more than a couple of times. If you left a comment on the survey that you would like addressed, you're welcome to bring it up in this thread.

Keep on keepin' on! I've noticed and like that more content is removed by the community, as opposed to being curated according to the mod. Thanks for working so hard to make this place awesome.
Thanks! We have been trying to let the community decide how grey-area posts and comments should be handled more often, and we think we're seeing positive results. Our goal is to act as janitors, not curators.

Watch the ableism!
We're happy to hear more on this, if anyone wants to chime in. The members of our mod team represent a wide variety of abilities (both us ourselves and our children), but if we can do better then we would love more specific feedback here. Do keep in mind, however, that just because you see something posted doesn't mean the mod team is "allowing" it. It can take awhile for us to catch something, especially if it's taken awhile for anyone to report it.

Enforce the rules the same for everyone, not selectively. The rules around coronavirus postings (when the rule was still in place) is the latest example.
Modding this sub involves perhaps mostly grey area, and there will never be a time where we are all completely of one mind. We'll continue to do our best. The rules around the coronavirus posting offered no grey area until our recent update, however, so if any posts/comments slipped through at that time it was just a matter of them avoiding the filter.

The whole feel of JNMIL was so much more relaxed and approachable three and four years ago. The changes being made to protect the feelings of the few interfere with the availability of the many. Also, MIL In The Wild posts were such a great stress relief, please bring them back.
Agreed on the first point. Growing pains can be a bummer sometimes, but there just no is no getting back there with a sub of this size. We want to be as balanced as we can when it comes to protecting users versus censoring, but that's a toughy that'll never be really perfect.
As for MILitW posts... there are other subs for that sort of thing.

Ban the people from [drama subs] - all they do is accuse posters of being fakers and harrass people and I'd much rather fakers get internet points than someone get falsely accused.
That wouldn't do anything, tbh. Banning a user doesn't prevent them from reading the sub.

please feed bippy, i get the feeling a hungry bippy is like a hungry bunny- anything and anyone is game. jokes aside yall are great
We'll try, but not after midnight.

The short answer is add more mods. It might be helpful to base it on subscriber numbers. Like, one more for each 100k users. But only if you have good applicants. I've moderated an online community of 100k active users and some of my co-volunteers were assholes on a power trip, and I think you've mostly addressed that.
Adding new people, and determining whether they're trustworthy (and/or active) is a shockingly long and arduous process, but we're getting better at it, I think. Our current mod team is small and half of us are on a leave of absence, but everyone's pleasant af to work with, so that's nice.

Have mods patrolling new/hot. It seems like all the new mods being talked about are just the programmers and no one is actively reading. And one mod actively reading new is not enough either.
Fair. I know some of us do this sometimes but mostly we end up going off user reports. We'll start encouraging this as we continue to grow the mod team.

Just let us be sarcastic against these women! Sometimes it's good to say these things to internet strangers, obviously we're not going to act on them.
Reddit policy is really strict on violence, and we want to discourage stuff like ableism, but other than that we're trying!

Mass deletions should probably require a second mod opinion. I did have a bad experience with a mod misreading and deleting dozens of comments for a reason I felt was not merited given what was actually said, not what they extrapolated. (Indirectly involved a hot button issue, but the advice was not about said issue.) I felt the mod wayyyy overstepped. Especially given that the advice deleted was standard for this sub.
This is a great suggestion and we're adding it as a policy update immediately. Thanks!

Be careful about people who scream about racism and any other form of bigotry. We live in a day and age in which people who didn't care for Black Panther will be called racist, and people who didn't watch the Ghostbusters remake will be called sexist. People who behave that way are going to raise the most hell over a post in which the toxic MIL happens to be, for example, HIspanic.
It's true that, if a post ever mentions a MIL's race/nationality/religion/etc in any context, there will be at least one person reporting it as racist/etc. Which invariably leads to a long internal discussion, which may or may not lead to visible results for the users.
But the new Ghostbusters was good and I'll fight anyone who says otherwise.

Read the threads, you know when they’re pushing the line. We all see the fat comments, the poor comments.
There are thousands of comments a day, so, no, we don't all see these comments. Even if we had a large mod team we wouldn't see all the comments. But we do see user reports fairly quickly, depending on the time it's reported.

I'd like to see comments removed/edited that refer to JNs being bad simply because of their age or having gone through menopause ("dried up hag")
We had a long discussion about the "menopause" comments a few months ago and have been removing them. We'll discuss adding the word to our alerts, now that you mention it. Other age-ist commentary we'll have to discuss further. We don't want to bar people from snarky venting--that's half the point of the sub. Ageism in particular came up a lot in the comments, so if anyone would like to discuss this further, please do chime in.

This is a support sub, so to prevent karma farmers just wanting to tell everyone they’re awesome you should disable comments for no advice wanted posts. They don’t want advice they want validation and if you remove that incentive it will stop some karma farmers.
This is a support sub first, and an advice sub second.

Add a reporting option for fakes.
The report options are tied to the rules, and we're trying to keep our rules list to a minimum. There is an "Other" option where you can put a custom response though.

No suggestions, users need to stop taking fake stories so personally. Fake stories are not posted AT them, the cost is only that they were moved to care a little for someone who didn’t deserve it. Fakers, at their core, are sad people. They have nothing better to do than to craft elaborate stories for internet points. It’s pathetic, but it doesn’t really affect my life in a meaningful way. I agree with everything the mods outlined in the explanation above, demanding that users essentially doxx themselves just so someone doesn’t accidentally read a piece of fiction goes way too far (and you guys have enough unpaid work to do without adding on to it).
I just really like this comment.

I've noticed users stories mimic or seem exaggeratedly close to TV plots- is there a way to screen for that
I can't begin to imagine how, tbh. But we do welcome users to modmail us their concerns about users, and we do look into those concerns.

Fear mongering rules need more strict enforcement
This rule was originally designed to curb the unwarranted jumps to "She's going to kidnap/murder your baby!" Sometimes those jumps are reasonable. It's one of those big grey areas, though, so we'll have to keep working on it.

I want to share my story to help me process it; I'm going to be starting therapy soon, and I have a feeling it's going to shake a lot loose. I am VERY anxious that parts of my story will trigger accusations that I'm making it up. (I have severe anxiety as it is.) I would very much like to know that if I even see that type of comment start, that there is a process in place for me to immediately "stand up for myself" (something I have trouble with, because being raised by Ns, I'm ALWAYS "wrong and oversensitive") and seek to prove what I can. Otherwise, I know myself well enough to know that the invalidation will shoot my anxiety to 11, and I'll ghost. I'm perfectly happy to get constructive criticism... just don't freaking call me a liar or an exaggerator about what I've lived. (And some of it, especially the last few years, is out there. And somewhat similar to another poster who I've observed being heavily harassed. Problem is, my "outcome" if you will, has been more positive/optimistic - and I expect that would get even more disbelief.)
We want to be able to help with situations like this, but we also want to be realistic about what we can do. We can't preemptively stop people from leaving shitty comments most of the time. We also cannot stop people from sending shitty DMs. We do remove shitty comments as soon as we're able, so our recommendation in cases like these is, if you see a shitty comment to report it and then leave the thread be for a bit. Or send us a modmail and we can follow up with you directly. In the case of the later, please be sure to reference specific comments, though, because it does happen sometimes where an OP messages us about users leaving rude comments but all the comments in the thread seem fine.

I feel like BotinLaw might often be on the fritz? I’d love it if there was a temporary stickied post that alerted us to that fact, like “experiencing technical difficulties, back online shortly”
If it's not working then that just means one of us needs to restart it. If it's been not working for a few hours then it just means that we haven't noticed yet, or that all of the people with the password are AFK.
------------------------------------
Thank you again for all of the lovely, sometimes amusing, and often thought-provoking comments! Again, please do comment below if there's any further discussion you would like to have at this time. We've gotten into the habit of starting next season's survey immediately after the current, so we're happy to receive any kind of suggestions.
Regardless, take care of yourselves and stay well!

Subreddit Demographic Survey 2019 : The Results

Subreddit Demographic Survey 2019

1. Introduction

Once a year, this subreddit hosts a survey in order to get to know the community a little bit and in order to answer questions that are frequently asked here. Earlier this summer, a few thousand of you participated in a massive Subreddit Demographic Survey.
Unfortunately during the process of collating results we lost contact with SailorMercure, who in previous years has completed all of the data analysis from the Google form responses. We were therefore required to collate and analyse the responses from the raw data via Excel. I attach the raw data below for those who would like to review it. For 2020 we will be rebuilding the survey from scratch.
Raw Data
Multiple areas of your life were probed: general a/s/l, education, finances, religious beliefs, marital status, etc. They are separated in 10 sections:
  1. General Demographics
  2. Education Level
  3. Career and Finances
  4. Child Status
  5. Current Location
  6. Religion and Spirituality
  7. Sexual and Romantic Life
  8. Childhood and Family Life
  9. Sterilization
  10. Childfreedom

2. Methodology

Our sample is people from this subreddit who saw that we had a survey going on and were willing to complete the survey. A weekly stickied announcement was used to alert members of the community that a survey was being run.

3. Results

5,976 participants over the course of two months at a subscriber count of 588,488 (total participant ratio of slightly >1%)

4. Discussion

Section 1 : General Demographics

The demographics remain largely consistent with the 2018 survey. 85% of the participants are under 35, compared with 87.5% of the subreddit in the 2018 survey. 71.54% of the subreddit identify as female, compared with 70.4% in the 2018 survey. This is in contrast to the overall membership of Reddit, estimated at 74% male according to Reddit's Wikipedia page [https://en.wikipedia.org/wiki/Reddit#Users_and_moderators]. There was a marked drop in the ratio of members who identify as heterosexual, from 67.7% in the 2018 survey to 54.89% in the 2019 survey. Ethnicity wise, 77% of members identified as primarily Caucasian, a slight drop from the 2018 survey, where 79.6% of members identified as primarily Caucasian.
Further research may be useful to explore the unusually high female membership of /childfree and the potential reasons for this. It is possible that the results are skewed towards those more inclined to complete a survey.
In the 2018 survey the userbase identified the following missing ethicities:
This has been rectified in the current 2019 survey.

Section 2 : Education level

As it did in the 2018 survey, this section highlights the stereotype of childfree people as being well educated. 4% of participants did not complete high school, which is a slight increase from the 2018 survey, where 3.1% of participants did not graduate high school. This could potentially be explained by the slightly higher percentage of participants under 18. 5.6% of participants were under 18 at the time of the 2018 survey, and 8.2% of participants were under 18 at the time of the 2019 survey.
At the 2019 survey, the highest percentage of responses under the: What is your degree/major? question fell under "I don't have a degree or a major" (16.9%) and "other" (9.71%). However, of the participants who were able to select a degree and/or major, the most popular responses were:
Response Participants # Percentage
Health Sciences 498 8.33%
Engineering 455 7.61%
Information and Communication Technologies 428 7.16%
Arts and Music 403 6.74%
Social Sciences 361 6.04%
Compared to the 2018 survey, health sciences have overtaken engineering, however the top 5 majors remain the same. There is significant diversity in the subreddit with regards to chosen degree/major.

Section 3 : Career and Finances

The highest percentage of participants (17.7%) listed themselves as a student. However, of those currently working, significant diversity in chosen field of employment was noted. This is consistent with the 2018 survey. The highest percentage of people working in one of the fields listed remains in Healthcare and Social Services. This is slightly down from the 2018 survey (9.9%) to 9.5%.
One of the stereotypes of the childfree is of wealth. However this is not demonstrated in the survey results. 72.4% of participants earn under $60,000 USD per annum, while 87.5% earn under $90,000 per annum. 26.2% are earning under $15,000 per annum. The results remain largely consistent with the 2018 survey. 1127 participants, or 19% chose not to disclose this information. It is possible that this may have skewed the results if a significant proportion of these people were our high income earners, but impossible to explore.
A majority of our participants work between 30 and 50 hours per week (71.2%) which is markedly increased from the 2018 survey, where 54.6% of participants worked between 30 and 50 hours per week.

Section 4 : Child Status

This section solely existed to sift the childfree from the fencesitters and the non childfree in order to get answers only from the childfree. Childfree, as it is defined in the subreddit, is "I do not have children nor want to have them in any capacity (biological, adopted, fostered, step- or other) at any point in the future." 68.5% of participants actually identify as childfree, slightly up from the 2018 survey, where 66.3% of participants identified as childfree. This is suprising in reflection of the overall reputation of the subreddit across reddit, where the subreddit is often described as an "echo chamber".

Section 5 : Current Location

The location responses are largely similar to the 2018 survey with a majority of participants living in a suburban and urban area. 86.7% of participants in the 2019 survey live in urban and suburban regions, with 87.6% of participants living in urban and suburban regions in the 2018 survey. There is likely a multifactorial reason for this, encompassing the younger, educated skew of participants and the easier access to universities and employment, and the fact that a majority of the population worldwide localises to urban centres. There may be an element of increased progressive social viewpoints and identities in urban regions, however this would need to be explored further from a sociological perspective to draw any definitive conclusions.
A majority of our participants (60.9%) live in the USA. The United Kingdom (8.1%), Canada (7.9%), Australia (3.6%) and Germany (2.2%) encompass the next 4 most popular responses. Compared to the 2018 survey, there has been a slight drop in the USA membership (64%), United Kingdom membership (7.3%) Canadian membership (8.1%), Australian membership (3.8%). There has been a slight increase in German membership, up from 1.7%. This may reflect a growing globalisation of the childfree concept.

Section 6 : Religion and Spirituality

A majority of participants were raised Christian (64.1%) however the majority are currently aetheist (55.6%) or agnostic (20.25%). This is consistent with the 2018 survey results.
A majority of participants (62.8%) rated religion as "not at all influential" to the childfree choice. This is consistent with the 2018 survey where 60.9% rated religion as "not at all influential". Despite the high percentage of participants who identify as aetheist or agnostic, this does not appear to be related to or have an impact on the childfree choice.

Section 7 : Romantic and Sexual Life

60.7% of our participants are in a relationship at the time of the survey. This is an almost identical result to the 2018 survey, where 60.6% of our participants were in a relationship. A notable proportion of our participants are listed as single and not looking (23.8%) which is consistent with the 2018 survey. Considering the frequent posts seeking dating advice as a childfree person, it is surprising that such a high proportion of the participants are not actively seeking out a relationship.
Participants that practice ethical non-monogamy are unusual (17.7%) and this result is consistent with the results of the 2018 survey. Despite the reputuation for childfree people to live an unconventional lifestyle, this finding suggests that a majority of our participants are monogamous.
84.2% of participants with partners of some kind have at least one childfree partner. This is consistent with the often irreconcilable element of one party desiring children and the other wishing to abstain from having children.

Section 8 : Childhood and Family Life

Overall, the participants skew towards a happier childhood.

Section 9 : Sterilization

While just under half of our participants wish to be sterilised, 46.3%, only 11.7% have been successful in achieving sterilisation. This is likely due to overarching resistance from the medical profession however other factors such as the logistical elements of surgery and the cost may also contribute. This is also a decrease from the percentage of participants sterilised in the 2018 survey (14.8%). 31.1% of participants do not wish to be or need to be sterilised suggesting a partial element of satisfaction from temporary birth control methods or non-necessity from no sexual activity.
Of the participants who did achieve sterilisation, a majority began the search between 19 and 29, with the highest proportion being in the 25-29 age group (33.2%) This is a drop from the 2018 survey where 37.9% of people who started the search were between 25-29.
The majority of participants who sought out and were successful at achieving sterilisation, were again in the 25-29 age group (37.8%). This is consistent with the 2018 survey results.
Over half of the participants who were sterilised had the procedure completed in less than 3 months (58.5%). This is a decline from the number of participants who achieved sterilisation in 3 months in the 2018 survey (68%). The proportion of participants who have had one or more doctors refuse to perform the procedure has stayed consistent between the two surveys.

Section 10 : Childfreedom

The main reasons for people chosing the childfree lifestyle are a lack of interest towards parenthood and an aversion towards children. Of the people surveyed 63.8% are pet owners, suggesting that this lack of interest towards parenthood does not necessarily mean a lack of interest in all forms of caretaking. The community skews towards a dislike of children overall which correlates well with the 81.4% of users choosing "no, I do not have, did not use to have and will not have a job that makes me heavily interact with children on a daily basis" in answer to, "do you have a job that heavily makes you interact with children on a daily basis?".
A vast majority of the subreddit identifes as pro-choice (94.5%). This is likely due to a high level of concern about bodily autonomy and forced parenthood. However only 70% support financial abortion for the non-pregnant person in a relationship to sever all financial and parental ties with a child.
45.9% identify as feminist, however many users prefer to identify with egalitarianism or are unsure. Only 8% firmly do not identify as a feminist.
Most of our users realised that did not want children young. 60% of participants knew they did not want children by the age of 18, with 96% of users realising this by age 30. This correlates well with the age distribution of participants. Despite this early realisation of our childfree stance, 80.4% of participants have been "bingoed" at some stage in their lives. Only 13% of participants are opposed to parents making posts on this subreddit.
Bonus section: The Subreddit
In light of the "State of the Subreddit" survey from 2018, some of the questions from this survey were added to the current Subreddit Survey 2019.
By and large our participants were lurkers (66.17%). Our participants were divided on their favourite flairs with 33.34% selecting "I have no favourite". The next most favourite flair was "Rant", at 20.47%. Our participants were similarly divided on their least favourite flair, with 64.46% selecting "I have no least favourite". Potentially concerningly were the 42.01% of participants who selected "I have never participated on this sub", suggesting a disparity between members who contributed to this survey and members who actually participate in the subreddit. To further address this, next year's survey will clarify the "never participated" option by specifying that "never participated" means "never up/downvoting, reading posts or commenting" in addition to never posting.
A small minority of the survey participants (6.18%) selected "yes" to allowing polite, well meaning lectures. An even smaller minority (2.76%) selected "yes" to allowing angry, trolling lectures. In response to this lectures remain not tolerated, and removed on sight or on report.
Almost half of our users (49.95%) support the use of terms such as breeder, mombie/moo, daddict/duh on the subreddit, with a further 22.52% supporting use of these terms in context of bad parents only. In response to this use of the above and similar terms to describe parents remains permitted on ths subreddit.
55.3% of users support the use of terms to describe children such as crotchfruit on the subreddit, with a further 17.42% of users supporting the use of this and similar terms in context of bad children only. In response to this use of the above and similar terms to describe children remains permitted on ths subreddit.
56.03% of participants support allowing parents to post, with a further 28.77% supporting parent posts dependent on context. In response to this, parent posts will continue to be allowed on the subreddit. Furthermore 66.19% of participants support parents and non childfree making "I need your advice" posts, with a further 21.37% supporting these dependent on context. In light of these results we have decided to implement a new "regret" flair to better sort out parents from fencesitters, which will be trialed until the next subreddit survey due to concern from some of our members. 64.92% of participants support parents making "I support you guys" posts. Therefore, these will continue to be allowed.
71.03% of participants support under 18's who are childfree participating in the subreddit. Therefore we will continue to allow under 18's that stay within the overall Reddit age requirement.
We asked participants their opinion on moving Rants and Brants to a stickied weekly thread. Slightly less than half (49.73%) selected leaving them as they are in their own posts. In light of the fact that Rants are one of the participant's favourite flairs, we will leave them as they are.
There was divide among participants as to whether "newbie" questions should be removed. An even spread was noted among participants who selected remove and those who selected to leave them as is. We have therefore decided to leave them as is.

5. Conclusion

Thank you to our participants who contributed to the survey. To whoever commented, "Do I get a donut?", no you do not, but you get our appreciation for pushing through all of the questions!
Overall there have been few significant changes in the community from 2018.

Thank you also for all of your patience!

A complete guide of and debunking of audio on Linux, ALSA and Pulse

Hey fellow penguins,
A few days ago, an user asked about audio quality on Linux, and whether it is worse or better than audio on Windows. The thread became a mess quickly, full of misconceptions and urban myths about Linux. I figured it would be worthwhile to create a complete guide to Linux audio, as well as dispelling some myths and misconceptions.
To all be on the same page, this is going to be thorough, slowly introducing more concepts.

What is sound? How and what can I hear?

You might remember from high school that sound is waves traveling through the air. Vibrations of any kind cause molecules in the air to move. When that wave form finds your ears, it causes little hairs in your ear to move. Different hairs are susceptible to different frequencies, and the signals sent by these hairs are turned into sound you hear by your brain.
In reality it is a little more complicated, but for the sake of this post, that's all you need to know.
The pitch of sound comes from its frequency, the 'shorter' the waves are in a waveform, the higher the sound. The volume of sound comes from how 'tall' the waves are. Human hearing sits in a range between 20Hz and 20,000 Hz, though it deviates per person. Being the egocentric species we are, waves below 20 Hz are called 'infrasound' and waves above 20kHz are called 'ultrasound.' Almost no humans can hear beyond ultrasound, you will find that your hearing probably cuts off at 16kHz.
To play around with this, check out this tone generator, you can prove anything above with this yourself. As a fun fact: human hearing is actually really bad, we've among the most limited frequency ranges. A cat can hear up to 40kHz, and dolphins can even hear up to 160kHz!!
FACT: Playing loud music is dangerous! If you listen to music and you are feeling a discomfort, you should turn the volume down. A true alert is when you hear a beep - this is called tinnitus, and that beep you're hearing is pretty much the death cry of the cells that can hear that frequency. That beep is the last time you will hear that very specific frequency ever again. Please, listening to loud music is not worth the permanent hearing damage, please dial it down for your own sake! <3

How does my computer generate sound?

To listen to sound, you will probably be using headphones or speakers, inside of them are cones that are driven by an electromagnet, causing them to vibrate at very precise frequencies. This is essentially how sound works, though modern headphones certainly can be pretty complex.
To drive that magnet, an audio source will send an analog signal (a waveform) over a wire to the driver, causing it to move at the frequency of that waveform. This is in essence how audio playback works; and we're not going to get into it much deeper than this.
Computers are digital - which is to say, they don't do analog; processors understand ON and OFF, they do not understand 38.689138% OFF and 78.21156% ON. When converting an analog signal (like sound) to a digital one, we make use of a format called PCM. For PCM to be turned into an analog signal, you need a DAC - or as you probably know it: a sound card. DAC stands for 'Digital to Analog Converter', or some people mistakenly call it "Digital Audio ConverteChip"
PCM stands for Pulse-code Modulation, which is a way to represent sampled analog signals in a digital format. We're not going to get into it too much here, but imagine taking a sample of a waveform at regular intervals and storing the value, and then rounding that value to a nearest 'step' (remember this). That's PCM.
The fidelity of PCM comes from two elements, which we are going to discuss next: sampling rate and bit depth.

What is sampling rate? Or: HOW SOUND GOOD?

Sampling rate is the most important part of making PCM sound good. Remember how humans hear in a range of 20Hz to 20kHz? The sample rate of audio has a lot to do with this. You cannot capture high frequencies if you do not capture samples often enough. Since our ears can hear up to 20 kHz, you would imagine that 20kHz would be ideal for capturing audio; however, a result of sampling is that you actually need twice the sample rate, this is called the Nyquist-Sannon sampling theorem, which is a complicated thing. Just understand that to reproduce a 20kHz frequency, you need a sample rate of 40kHz.
To have a little bit of room and leeway, we settled on a sample rate of 48kHz (a multiple of 8) for playback, and 96kHz for recording. We record at this frequency only to make sure absolutely no data is lost. You might be more familiar with 44.1kHz for audio, which is a standard we settled on for CD playback and NTSC. A lot of scientific research has been done on sound quality, and there is no evidence to suggest people can tell the difference between 48kHz or anything higher.
MYTH BUST: Humans cannot hear beyond 20 kHz, period. Anyone who claims to be able to is either supernatural or lying to you - I'll let you choose which.

What is bit-depth? Or: HOW IT MAKE SOUND REALLY NICE?

Remember how I told you to remember that PCM rounds values to the nearest step? This has to do with how binary works. The more bits, the bigger the number you can store. In PCM, the bit-depth decides the number of bits of information in each sample. With 16-bit, the range of values that can be stored is 0 to 65535. Going beyond this is pointless for humans, with no scientific research showing any proven benefit, though marketeers would like you to believe there's benefits.
MYTH BUST: 24-bit depth is often touted as 'high-resolution audio', claiming benefits of a better sonic experience. Such is nothing more than marketing speech, there is no meaningful data 24-bit can capture that 16-bit cannot.

Channels? Or: HOW IT CAN MAKE SOUND IN LEFT BUT NOT RIGHT?

We'll briefly touch on the last part of PCM audio, channels. This is very self explanatory, humans have two ears and can hear separate sounds on both of them, which means we have stereo hearing. As a result, most music is recorded with 2 channels. For some surround settings, you need more channels, this is why you may have heard of 5.1 or 7.1; the first digit is the amount of channels the PCM carries.
For most desktop usage, the only sound we care about is 2-channel PCM.

Recap

So, we've covered all the elements of PCM sound. Let's go over it quickly: sample rate is expressed in Hz and is how often a sample of a waveform is captured, representing the x-axis of a waveform. Bit-depth is the bits of information stored in each sample, and represents the y-axis of the waveform. Channels decide how many simultaneous outputs the PCM can drive separately, since we have 2 ears, you need at least two channels.
As a result, the standard audio playback for both consumers and professionals is 48kHz, 16-bit, 2 channel PCM. This is more than enough to fully represent the full range of human hearing.

How it works in Linux

So, now that we know how PCM works, how does Linux make sound? How can you make Linux sound great? A few important components come into play here, and we'll need to discuss each of them in some detail.

ALSA

ALSA is the interface to the kernel's sound driver. ALSA can take a PCM signal and send it to your hardware by talking to the driver. Something important to know about most DACs is that they can only take one signal at a time, actually. That means that only a single application can send sound to ALSA at once. Long ago, in a darker time, you couldn't watch a movie while listening to music!
This problem was solved a long time ago with the use of alsalib, but doing mixing at a library level isn't a very good solution to the problem. This gave rise to sound servers, of which many have existed. Before PulseAudio, esound was a very popular one but had many problems, eventually it was succeeded by PulseAudio.

PulseAudio

When you think audio on Linux, PulseAudio is probably among the first things you think of. PulseAudio is NOT a driver, nor does it talk to your drivers. Actually, PulseAudio only does two things that we'll discuss in detail later. PulseAudio talks to ALSA, taking control of its single audio stream, and allows other applications to talk to PulseAudio instead. Pulse is an 'audio multiplexer', turning multiple signals into one through a process that is called mixing. Mixing is an incredibly complicated subject that we won't talk about here.
To be able to mix sounds, one must make sure that all the PCM sources are in the same format (the one that's being sent to ALSA); if the PCM format being sent to Pulse does not match the PCM format being sent to ALSA, pulse does a step before mixing it called resampling. Resampling is another very complicated subject that can turn a 8kHz, 4-bit, 1-channel PCM stream into a 24kHz, 24-bit, 2-channel PCM stream.
These two things allow you to play a game, listen to music and watch YouTube, and notifications to produce a sound all at the same time. PulseAudio is the most critical element of the Linux sound stack.
FACT: PulseAudio is a contentious subject, many people have a dislike for this particular bit of software. In all honesty, PulseAudio was brought to the general public in a bit of a premature state, breaking audio for many people. PulseAudio these days is a very stable, solid piece of software. If you have audio issues these days, it's usually a problem in ALSA or your driver.

What about JACK and PipeWire?

PulseAudio isn't the only sound servedaemon available for Linux, though it is certainly the most popular and most likely the default of whatever distribution you are using. PulseAudio has become a bit of a standard for Linux sound and has by far the best compatibility with most applications, but that doesn't mean there aren't alternatives.
JACK (JACK Audio Connection Kit, a recursive acronym like GNU) is a sound server focused primarily on low latency. If you are doing professional audio work on Linux, you will already be very familiar with JACK. JACK's development is very focused on low latency, real-time audio and is critical for such people. JACK is available on most distros as an alternative, and you can try it for yourself if you so want; but you might find some applications do not work nicely with JACK.
PipeWire is a project that is currently in development, looking to solve key problems that exist in current sound servers. PipeWire isn't just a sound server but also handles the multiplexing of video sources (like a camera). Special attention has been put into working with sandboxed applications (like Flatpaks), which is an area where PulseAudio is lacking. PipeWire is a very promising project that might very well succeed PulseAudio in the future and you should expect to see appearing in distribution repositories very soon. You can try it yourself right now, though it isn't quite as easy to get started with as JACK is.
More audio servers exist, but are beyond the scope of this post.

What is resampling?

Resampling is the process of turning a PCM stream into another PCM stream of a different resolution. Your DAC only accepts a limited range of PCM signals, and it is up to the software to make sure the PCM stream is compatible. There is almost no DAC out there that doesn't support 44.1kHz, 16-bit, 2-channel PCM, so this tends to be the default. When you play an audio source (like an OggVorbis file), the PCM stream might be 96kHz, 24-bit, 2-channel PCM.
To fix that, PulseAudio will use a resampling algorithm. There are two kinds of resampling methods: upsampling and downsampling. Upsamling is lossless, since you can always represent less data with more data. Downsampling is lossy by definition, you cannot represent 24-bit PCM with 16-bit PCM.
MYTH: Downsampling is a loss in quality! This is only true in a technical sense, or if you are downsampling to less than 48kHz, 16-bit PCM. When you downsample a 96kHz, 24-bit PCM stream to a 48kHz, 16-bit stream, no meaningful data is lost in the process; because the discarded data lies outside of the human ear's hearing range.
FACT: Resampling is expensive. Good quality resampling algorithms actually take a non-trivial amount of processing power. PulseAudio defaults to a resampling method with a good balance between CPU time used and quality.

What is mixing?

Mixing is the process of taking two PCM streams and combining them into one. This is extremely complicated and not something we're going to discuss at length. It is not important to understand how this works, only to understand that it exists. Without mixing, you wouldn't be able to hear sounds from multiple sources. This is true not just for PulseAudio and computer sound, this is true for anything. In real life, you might use an A/V receiver to accept sound from your TV and music player at once, the receiver then mixes the signals and plays it through your speakers.

What is encoding?

Finally we can talk a little about encoding. Encoding is the process of taking a PCM stream and writing it to a permanent format, two types exist. You have lossy encoding and lossless encoding. Lossy encoding removes data from the PCM stream to safe space. Usually the discarded data is useless to you, and will not make a difference in sound quality; examples of lossy encoding are MP3, AAC and Ogg Vorbis. Lossless encoding takes a PCM stream and encodes it in such a way that no data is lost, examples of lossless encodings are FLAC, ALAC and WAV.
Note that lossy and lossless do not mean compressed and uncompressed. A lossless format can be compressed and usually is, as uncompressed lossless encoding would be very large; it would just be the raw PCM stream. An example of lossless uncompressed audio is WAV.
A new element encodings bring is their bit rate, not to be confused with samplerate and bit depth. Bit rate has to do with how much data is stored in every second of audio. For a lossless, uncompressed PCM stream this is easy to calculate with the formula bit rate = sample rate * bit depth * channels, for 16-bit, 48kHz, 2 channel PCM this is 1,5 Mbit. To get the value in bytes, divide by 8, thus 192kB per second.
The bit rate of an encoder means how much the audio will be compressed. PCM compression is super complicated, but it generally involves discarding silence, cutting off frequencies you cannot hear, and so forth. Radio encoding has a bit rate of roughly 128 Kbps, while most CDs have a bit rate of 1360kbps.
Lastly, there is the concept of VBR and CBR. VBR stands for Variable Bit Rate, which CBR stands for Constant Bit Rate. In a VBR encoding, the encoder aim for a target bit rate that you set, but it can deviate if it thinks it needs more or less. CBR will encode a constant bit rate, and will never deviate.
MYTH: Lossless sounds better than lossy. This is blatantly untrue, lossless audio formats were created for perservation and archival reasons. When you encode a lossy file from a lossless source, and you make sure that it's a 48kHz, 16-bit PCM encoding, you will not lose any important information. What is enough depends on the quality of the encoder. For OggVorbis, 192kbps is sufficient, for MP3, 256kbps should be preferred. 320kbps is excessive and the highest quality supported by MP3. In general, 256kbps does the trick, but with storage being abundant these days, you can play it safe and use 320kbps if it makes you feel better.
MYTH: CBR is better than VBR. There is no reason not to use VBR at all, there is no point in writing 256Kbps of data if there is only silence or a constant tone. Let your encoder do what it does best!
FACT: Encoding a lossy format to another lossy format will result in a loss of data! You will compress data that is already compressed, which is really bad. When encoding to a lossy format, always use a high quality recording in a lossless format as the source!
I DON'T BELIEVE YOU: This article from the guys Xiph (the people who brought you FLAC and Ogg Vorbis) explain it better than I can: https://people.xiph.org/%7Exiphmont/demo/neil-young.html

TL;DR, I JUST WANT THE BEST SOUND QUALITY

Here is a quick guide to achieving great sound quality on Linux with the above in mind.
As you can see, there's little you can do in Linux in the first place, so what can you do if you want better sound?
MYTH: Linux sound quality is worse than Windows. They are exactly the same, Pulse doesn't work that different from how Windows does mixing and resampling.
MYTH: Linux sound quality can be better than Windows. They are exactly the same. All improvements in quality come from the driver and your DAC, not the sound server. Pulse and ALSA do not touch the PCM beyond moving it around and resampling it.
I hope this (long) guide was of help to you, and helped to dispell some myths. Did I miss anything? Ask or let me know, and I'll answer the best I can. Did I make any factual errors? Please correct me with a source and I'll amend the post immediately.
