 # Contributing to bobatheme
 
-## Where to put stuff
-
-### Discussions
-
-The best place to ask questions or have discussions is the (relatively new)
-discussions feature on GitHub, available
-[here](https://github.com/BBaoVanC/bbaovanc.com/discussions). It's not too big
-of an issue though because discussions and issues can easily be converted
-between eachother.
-
-### Issues
-
-Issues should be used only for, well, issues. Ignore all the placeholder ones
-prefixed with "Translate:" and tagged with the "translation" tag as they are
-placeholders used in the projects tab. I might mark them as closed in the future
-to clean it up but I'll worry about that later.
-
-### Translations
-
-Discussion relating to translations should either go as comments or reviews on
-the pull request adding the translation, or as a discussion under the
-[Translations category](https://github.com/BBaoVanC/bbaovanc.com/discussions/categories/translations).
-
-## Writing translations
-
-Translations should aim to get the meaning as close as possible to original
-document. The changes in a translation pull request *should*:
-
-- only update one page (multiple pages should be split into separate pull
-  requests)
-- only contain changes for a single new file (no changes unrelated to
-  translation)
-- thoroughly compared to the original text in order to get the same meaning
-  across
-
-## Pull requests
-
-### Commit messages
-
-It's not too big of a deal what you put in your commit messages, but try to give
-each commit a rough description of what it changes. I'll use squash merges most
-of the time anyways.
-
-### Description
-
-If the pull request doesn't require any extra information in addition to the
-title, you can probably leave the description blank. Otherwise you can put some
-information, just try to keep it concise; it's better to read a couple sentences
-than an entire essay with the same amount of information.
-
 ## Building
 
-## Automatic deploy previews with Netlify
+Just in case you need it.
 
-Netlify will automatically build each pull request into a public deploy preview,
+### Automatic deploy previews with GitHub Actions
-and will link it in a comment.
 
-## Manual (local) building
+My GitHub Actions workflows will automatically build each pull request into a
+public deploy preview on demo.bbaovanc.com, and will link it in a comment.
+
+### Manual (local) building
 
 You can also build the site yourself using Hugo, including a live local preview.
 
-1. Make sure you install the latest version of Hugo, or at least the
+1. Make sure you install the latest version of Hugo, or hopefully at least the
    `min_version` listed in
    [theme.toml](https://github.com/BBaoVanC/bobatheme/blob/master/theme.toml#L11).
+   Let me know if that minimum version isn't enough and I'll fix it.
 2. Clone the repo
 3. Make sure to download and checkout the submodules (use `git submodule update
    --init --recursive`). The `--recursive` flag is especially important because

+By exercising the Licensed Rights (defined below), You accept and agree

+Attribution-ShareAlike 4.0 International Public License ("Public
+License"). To the extent this Public License may be interpreted as a

+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed
+     Material is a musical work, performance, or sound recording,
+     Adapted Material is always produced where the Licensed Material is
+     synched in timed relation with a moving image.
+
+  b. Adapter's License means the license You apply to Your Copyright
+     and Similar Rights in Your contributions to Adapted Material in
+     accordance with the terms and conditions of this Public License.

+     specified in Section 2(b)(1)-(2) are not Copyright and Similar
+     Rights.
+
+  e. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws
+     fulfilling obligations under Article 11 of the WIPO Copyright
+     Treaty adopted on December 20, 1996, and/or similar international
+     agreements.
+
+  f. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.

+     or other material to which the Licensor applied this Public
+     License.
+
+  i. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  j. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  k. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such

+     dissemination, communication, or importation, and to make material
+     available to the public including in ways that members of the
+     public may access the material from a place and at a time
+     individually chosen by them.
+
+  l. Sui Generis Database Rights means rights other than copyright
+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  m. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. Additional offer from the Licensor -- Adapted Material.
+               Every recipient of Adapted Material from You
+               automatically receives an offer from the Licensor to
+               exercise the Licensed Rights in the Adapted Material
+               under the conditions of the Adapter's License You apply.
+
+            c. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+

+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:

+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR

+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and

+       2. upon express reinstatement by the Licensor.

+
+  c. For the avoidance of doubt, the Licensor may also offer the

+
+  a. For the avoidance of doubt, this Public License does not, and

+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is

+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+
+The other day I set up automatic testing of my website using [Google Chrome
+Lighthouse][google-lighthouse]. I'm also running my own Lighthouse CI server to
+store test result history and show trends. Here's an outline of what this means,
+some of the results I've obtained so far, and my thoughts on the usefulness of
+Lighthouse.
+
+[google-lighthouse]: https://developers.google.com/web/tools/lighthouse
+
+<!--more-->
+
+## What is Lighthouse?
+
+Lighthouse is a tool developed by Google which audits websites and gives them a
+score in four categories: *Performance*, *Accessibility*, *Best Practices*, and
+*SEO (search engine optimization)*. It's also built into the developer console
+in Chrome, so you can run it manually on any website you want directly inside
+your browser.
+
+I have already been using Lighthouse manually to do occasional tests on my
+website and its theme, [bobatheme][bobatheme]. However, I recently came across
+[this GitHub Action][lhci-action]. It caught my eye because I was [already using
+GitHub Actions][old-audit-workflow] to perform a few basic Hugo[^hugo]-related
+audits found [in a thread on the Hugo forum][hugo-audits-thread].
+
+[^hugo]: [Hugo](https://gohugo.io) is the framework that my website is built on. It's
+  a static site generator which generates my site according to my own custom
+  templates that make up my theme.
+
+[bobatheme]: https://github.com/BBaoVanC/bobatheme
+[lhci-action]: https://github.com/marketplace/actions/lighthouse-ci-action
+[old-audit-workflow]: https://github.com/BBaoVanC/bbaovanc.com/blob/31e25c2578a789afe71ce90352747eb427ca3c0e/.github/workflows/audit.yml#L31-L59
+[hugo-audits-thread]: https://discourse.gohugo.io/t/audit-your-published-site-for-problems/35184
+
+## Setting it all up
+
+My goal is to run Lighthouse's audits on an environment as similar to my real
+website's deployment as possible.
+
+First, I [created a separate `lighthouse` job on my audit
+workflow][lighthouse-actions-job] on GitHub Actions. This job will do all of the
+testing. Since it's a separate job, it runs in parallel with my existing audit
+task.
+
+[lighthouse-actions-job]: https://github.com/BBaoVanC/bbaovanc.com/blob/3668b6cfb11d09149b5da347219cdc75d0ce0985/.github/workflows/audit.yml#L7
+
+Next, I copied [my existing build steps verbatim][production-build-steps]. This
+makes the site effectively identical to my real deployment on bbaovanc.com. One
+of the crucial steps is to pre-compress all the files so their compressed
+versions can be served without the server having to compress them on-the-fly,
+saving valuable processing power.
+
+[production-build-steps]: https://github.com/BBaoVanC/bbaovanc.com/blob/db65e9fc23b840429f5c9ad2b43d7dd01a024f36/.github/workflows/deploy.yml#L22-L33
+
+Serving the compressed files is crucial because it simulates the real world
+transfer size of the files. In addition, Lighthouse will recommend that you
+serve the files compressed.
+
+Inside the audit environment I use the same webserver (Caddy) and a [similar
+configuration][audit-caddy-config] (compared to the [one running on
+bbaovanc.com][production-caddy-config]) to what I have running on bbaovanc.com.
+Caddy also is able to easily run the demo site with HTTPS, even on localhost.
+That allows it to test certain elements (such as the comment section) that
+wouldn't be allowed to load if it were plain, unsecured HTTP.
+
+[audit-caddy-config]: https://github.com/BBaoVanC/bbaovanc.com/blob/3668b6cfb11d09149b5da347219cdc75d0ce0985/Caddyfile
+[production-caddy-config]: https://git.bbaovanc.com/configs/caddy/src/commit/e3227eb2a2679e27545c2417c2565941f03fb744/conf.d/bbaovanc.com
+
+{{< see-also "/blog/caddy-is-the-best-webserver" >}}
+
+I selected [a few significant pages on my website][lighthouse-urls] so
+Lighthouse can test a wide range of the features in my website's theme. The
+results of these tests are then uploaded to [my Lighthouse CI
+server][lhci-dashboard]. There you can view the audit history and see
+differences in results between builds.
+
+[lighthouse-urls]: https://github.com/BBaoVanC/bbaovanc.com/blob/3668b6cfb11d09149b5da347219cdc75d0ce0985/lighthouserc.yaml#L4-L19
+[lhci-dashboard]: https://lhci.bbaovanc.com/app/projects/bbaovanc.com/dashboard
+
+## What I found from the tests
+
+### Performance impact of a YouTube video
+
+I found that embedding a YouTube video using the built-in shortcode in Hugo
+made the website drastically slower. It's a lot clearer in the audit environment
+where everything is throttled down a bunch, so the performance impact is more
+clear. Below is a screenshot of the difference in score between my blog post
+with a YouTube embed and a similarly sized blog post which has no video.
+
+{{< figure src="youtube-embed-performance-comparison" >}}
+
+I can probably optimize this a little by making a copy of the built-in Hugo
+YouTube shortcode, and modifying it to defer the loading of the remote scripts.
+That will have to be a future project, and I'll probably write a post if I ever
+end up testing it.
+
+## My thoughts on Lighthouse
+
+You can make the argument that the results from Lighthouse don't really mean
+much in the real world. On modern devices and a decent internet speed most
+websites will load just fine.
+
+Although most pages on my site have a perfect score from Lighthouse, I'm not
+going to go way out of my way in order to keep it that way. After all,
+Lighthouse is just a tool intended for "improving the quality of web
+pages."[^improve-quality-quote] That doesn't mean it needs to be perfect.

+
+## Choosing the right mailing list manager
+
+For my newsletter manager, I chose [listmonk](https://listmonk.app/). As I was
+searching for self-hosted newsletter managers, it caught my eye because of how
+modern and beautiful its interface looks. In fact, it was the only self-hosted
+newsletter/mailing list manager I looked at that doesn't have an overall old and
+ugly interface. Additionally, it has a live demo, so I was able to test it out
+and see if it would be able to meet my (relatively low) requirements.
+
+{{< figure src="listmonk-splash" >}}
+
+I also tried out [GNU Mailman 3](https://www.list.org/) about a year ago.
+However, I could not get it to integrate cleanly with my email
+server[^mailman-mailcow]. listmonk can operate over SMTP, just like any other
+program that sends mail. That makes the setup much less complicated, and I was
+also able to set up the [official Docker
+image](https://listmonk.app/docs/installation/#docker) using Docker Compose
+setup just like the other programs I use.
+
+If you're interested, the Docker Compose configuration files I ended up writing
+are available at [configs/listmonk on my Gitea
+instance](https://git.bbaovanc.com/configs/listmonk).
+
+## Newsletter formatting
+
+I ended up writing my own template for listmonk from scratch, based on the CSS
+used in [bobatheme](https://github.com/BBaoVanC/bobatheme), the theme that my
+website uses. Here's a screenshot of how it currently looks:

+There's this trick going around on Discord recently where if you send any GIF

+Here's how it works.

+
+{{< aside info >}}
+Credit goes to Rebane2001 (not me) for making this trick, and setting it up on
+`txnor.com`.
+{{< /aside >}}
+
+## The `sed` syntax
+
+For operating systems based on Unix or Linux, there's usually a simple terminal
+command included called [`sed`][sed-wikipedia], which is most commonly used to
+run text replacement commands. Here's a very simple example of what a basic
+`sed` command looks like:
+
+[sed-wikipedia]: https://en.wikipedia.org/wiki/Sed
+
+```console
+$ sed 's/hello/goodbye/'
+```
+
+Discord likely implemented this in order to appeal to
+[IRC][irc-wikipedia][^irc-definition] users. Since IRC doesn't support editing
+messages, it's common for people to send messages in that format to tell people
+about changes to their previous message. Discord implemented this into both
+their web/desktop client and their iOS app, excluding the Android app.
+
+[irc-wikipedia]: https://en.wikipedia.org/wiki/Internet_Relay_Chat
+
+[^irc-definition]: IRC (Internet Relay Chat) is a simple text-based chat system.
+  It's a very old protocol, however its simplicity and minimalism is the main
+  reason people choose it. It's not very popular anymore.
+
+Note that while real `sed` commands can get much more complicated, Discord's
+implementation doesn't support those advanced features[^trailing-slash-note].
+
+[^trailing-slash-note]: Also note that in Discord's implementation, the trailing
+  slash (after `goodbye`) can be ommitted (making it just `s/hello/goodbye`),
+  but with the real `sed` command, it's required.
+
+{{< see-also "/blog/text-substitution-in-discord-using-sed" >}}
+
+## What does `s/e/x` do?
+
+When you send a GIF using the GIF picker on Discord, it actually sends the link
+to the GIF, which is served by [Tenor][tenor-website]. For example, here's a GIF
+sent from Tenor:
+
+[tenor-website]: https://tenor.com
+
+https://tenor.com/view/cat-massage-gif-24282757
+
+Running `s/e/x` will take the first occurrence of `e` and replace it with `x`.
+The link becomes the following (notice the bolded letter `x`):
+
+[https://t**x**nor.com/view/cat-massage-gif-24282757][example-1]
+
+[example-1]: https://txnor.com/view/cat-massage-gif-24282757
+
+Then, all that's left to do is to buy the domain `txnor.com`, and write a simple
+program to run on it. In fact, it looks like that domain was purchased purely in
+order to make this trick possible[^txnor-domain-date].
+
+[^txnor-domain-date]: According to [a quick WHOIS lookup][txnor-whois], the
+  domain was registered on May 3, 2022. That's the same day that [@Rebane
+  tweeted about the new feature][rebane-tweet] (~~going to https://txnor.com
+  redirects to this tweet~~ now the domain redirects to [Rebane's YouTube video
+  about the hack]({{< ref "#youtube-video" >}})), so I assume that this is the
+  only reason they bought the domain.
+
+[txnor-whois]: https://www.whois.com/whois/txnor.com
+[rebane-tweet]: https://twitter.com/rebane2001/status/1521544722875142145
+
+## How does it display on Discord without redirecting?
+
+When viewing any of the URLs on `txnor.com` in a normal web browser, you get
+[redirected to a tweet][rebane-tweet]. However, Discord is able to display the
+image without being redirected.
+
+When Discord loads a website to generate an embed, it uses a user
+agent[^user-agent-definition] (which is a little piece of text which tells the
+server what your browser is) which looks something like this:
+
+[^user-agent-definition]: If you actually care, there's a [Wikipedia
+  article](https://en.wikipedia.org/wiki/User_agent), and a [page on
+  WhatIsMyIPAddress.com](https://whatismyipaddress.com/user-agent) which also
+  explain what a user agent is.
+
+```text
+User-Agent: Mozilla/5.0 (compatible; Discordbot/2.0; +https://discordapp.com/)
+```
+
+The important part here is the word `Discord`. If you visit the website with
+your user agent set to anything containing `Discord`
+(case-insensitive)[^discord-user-agent], then it serves the image directly.
+
+[^discord-user-agent]: [According to the source code][user-agent-source-code],
+  it looks like `Intel Mac OS X 11.6; rv:92.0` also triggers the same response.
+
+[user-agent-source-code]: https://github.com/rebane2001/txnor-server/blob/26c7c279b0b4668c8a3b061692d83c507aeac7c5/txnor.nginx#L23-L27
+
+## Default image
+
+If you go to any URL on `txnor.com` that doesn't fit one of the existing
+patterns/games, then it returns this fallback image:
+
+{{< figure src="default-sex" >}}
+
+## Extra features
+
+### Double sex
+
+If you then run `s/e/x` a second time, then it changes to a different image:
+
+{{< figure src="double-sex" >}}
+
+This works in a simple way as well. The next `e` that appears in the URL is
+inside `/view/`. So, after typing `s/e/x` a second time, the URL becomes:
+
+[https://txnor.com/vi**x**w/cat-massage-gif-24282757][example-2]
+
+[example-2]: https://txnor.com/vixw/cat-massage-gif-24282757
+
+### Chess (`s/w/ag`)
+
+Another cool feature is that you can play chess by typing `s/w/ag` after typing
+the initial message of `s/e/x`.
+
+{{< figure src="chess" >}}
+
+### `s/w/ord`
+
+If you do `s/w/ord` after `s/e/x`, then it starts a fighting game (titled
+"Wumpagotchi Adventures". You can use three commands: s/d/d**ATK**,
+s/d/d**DEF**, and s/d/d**HUG**.
+
+Here are a few example images:
+
+#### Main `s/w/ord` screen
+
+{{< figure src="sword" >}}
+
+#### ATK command
+
+{{< figure src="sword-atk" >}}
+
+#### DEF command
+
+{{< figure src="sword-def" >}}
+
+#### HUG command
+
+{{< figure src="sword-hug" >}}
+
+#### Win screen
+
+{{< figure src="sword-win" >}}
+
+#### Lose screen
+
+{{< figure src="sword-lose" >}}
+
+### 6969th Discord Sexer
+
+If you happen to get a one in 6970 chance, it will instead return
+a special image:
+
+{{< figure src="6969th" >}}
+
+[6969th-source]: https://github.com/rebane2001/txnor-server/blob/26c7c279b0b4668c8a3b061692d83c507aeac7c5/sex.py#L130-L133
+
+Here's a [snippet of the code that handles this chance][6969th-source]:
+
+```python
+# 6969th winner image (disable for chess)
+if random.randint(0, 6969) == 6969 and "ag" not in name:
+    web.header('Cache-Control', 'no-store')
+    return six_nine
+```
+
+I believe it's supposed to be a 1/6969 chance, but `random.randint` in Python
+[includes both numbers][randint-inclusive]. That means that the possible numbers that it could pick
+would be 0, 1, ... 6968, 6969. If you were to count the numbers included in that
+sequence, it would total 6970.
+
+[randint-inclusive]: https://docs.python.org/3/library/random.html#random.randint
+
+### Math challenge
+
+Any URL that matches [this regular expression][math-challenge-regex] will
+instead return a randomized math challenge. This means the URL can be
+`https://txnor.com/` followed by either `math`, `math_challenge`, or
+`mathchallenge`, a single optional slash, and then any text that's made up of
+only letters, numbers, underscores or hyphens.
+
+[math-challenge-regex]: https://regex101.com/r/ddEkML/1
+
+{{< figure src="math-challenge" >}}
+
+What's special is that the math challenge is [set to not be
+cached][math-challenge-caching]. That means that it
+*should*[^should-different-question] give everyone a different question.
+
+[math-challenge-caching]: https://github.com/rebane2001/txnor-server/blob/26c7c279b0b4668c8a3b061692d83c507aeac7c5/sex.py#L137
+[^should-different-question]: The caching behavior seems to be inconsistent, so
+    sometimes it does end up giving multiple people the same question.
+
+How it works is that when each person's Discord client sends a request to the
+Discord CDN to get the image, the client caches that image. That means each
+client will see the same challenge problem, even if the user restarts the
+client. But separate clients will not have it cached, so they'll request it
+again themselves, and different numbers will be generated.
+
+## Discord sex is open source
+
+Thanks to a [comment from Rebane on this post](#isso-16), I now know that the
+server running on `txnor.com` is open source. See
+[rebane2001/txnor-server][txnor-server-github].
+
+[txnor-server-github]: https://github.com/rebane2001/txnor-server

+Rebane also [made a YouTube video][txnor-youtube-video] about this trick. Make
+sure to check it out too!

+
+## Should you use swap?
+
+A common misconception is that adding swap to your system can reduce
+performance. However, even if you aren't running out of RAM, it can still be
+beneficial to add swap.
+
+See these points according to [an article by Hayden James][always-add-swap]:
+
+> - Even if there is still available RAM, the Linux Kernel will **move memory
+>   pages that are hardly ever used** into swap space.
+>

+
+### Should you use a swap file or partition?
+
+Swap partitions should be preferred because swapfiles tend to be slower and
+slightly more complex to set up, especially if hibernating. A swapfile might be
+preferred due to its flexibility (ease to resize), but if you use
+[LVM][lvm-archwiki] then you can easily resize the swap partition anyways.
+
+[lvm-archwiki]: https://wiki.archlinux.org/title/LVM
+
+## Tutorial
+
+{{% include "snippets/console.md" %}}
+
+### Step 1: Create the file
+
+The first step is to allocate the file.
+
+```console
+# dd if=/dev/zero of=/swapfile bs=1M count=[size in MiB] status=progress
+```
+
+Replace `[size in MiB]` with the size of your swapfile in Mebibytes (MiB). You
+can use [this online converter](https://www.convertunits.com/from/GiB/to/MiB) to
+convert from Gibibytes (GiB, often confused with Gigabytes, but that's a
+misconception for another time) to MiB, which you can put in the command.
+
+Or you can look at this table for common sizes:
+
+| GiB | MiB         |
+|-----|-------------|
+| 1   | count=1024  |
+| 2   | count=2048  |
+| 3   | count=3072  |
+| 4   | count=4096  |
+| 8   | count=8192  |
+| 16  | count=16384 |
+{.simple}
+
+If you aren't sure how big your swapfile should be, take a look at [Table 15.1
+on this Red Hat documentation page][redhat-swap-table]. Remember that if your
+first swapfile isn't large enough, you can create another one.
+
+[redhat-swap-table]: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/storage_administration_guide/ch-swapspace#tb-recommended-system-swap-space
+
+On my computer I have 32 GiB of RAM and a 16 GiB swap partition, rather than
+swapfile, because I can flexibly expand the swap partition using
+[LVM][lvm-archwiki].
+
+{{< aside example >}}
+
+To create a swapfile 4 GiB in size, you would run:
+
+```console
+# dd if=/dev/zero of=/swapfile bs=1M count=4096 status=progress
+4096+0 records in
+4096+0 records out
+4294967296 bytes (4.3 GB, 4.0 GiB) copied, 0.960183 s, 4.5 GB/s
+```
+
+{{< /aside >}}
+
+### Step 2: Change swapfile permissions
+
+The swapfile should only be readable by the system (`root` user). Run this
+command to change it:
+
+```console
+# chmod 600 /swapfile
+```
+
+### Step 3: Format the swapfile
+
+Use the `mkswap` command to format the file to be used as swap (basically just
+add a header to identify it):
+
+```console
+# mkswap /swapfile
+Setting up swapspace version 1, size = 4 GiB (4294963200 bytes)
+no label, UUID=a0b87eca-b951-4344-be2d-020d77cdef48
+```
+
+### Step 4: Create an entry in `/etc/fstab`
+
+An entry needs to be added to `/etc/fstab` for the swapfile to be enabled during
+bootup. Open `/etc/fstab` in a text editor, and add this line to the end (add
+spaces to line up with other entries if you want, whitespace is ignored):
+
+```text
+/swapfile none swap sw 0 0
+```
+
+{{< aside note >}}
+
+Above, I have filled the "options" field with `sw`. Some guides suggest using
+either `sw` or `defaults`. Neither of those options is valid for `swapon` and
+they are both ignored. However, the field does need to be filled out with
+something, so feel free to put something funny (do let me know in the comments
+if this somehow breaks something though).
+
+If you're curious, this is my `fstab` entry (`UUID` is because I use a swap
+partition, rather than swapfile):
+
+```text
+# /dev/mapper/bobavg0-swap
+UUID=4f7c3ae8-839b-4474-b8a5-96bd78db06f8 none swap bobaswap 0 0
+```
+
+{{< /aside >}}
+
+### Step 5: Enable the swapfile
+
+Adding the `fstab` entry won't enable the swapfile until a reboot. To enable it
+now, use the `swapon` command.
+
+```console
+# swapon /swapfile
+```
+
+### Finally: check the swap status
+
+Use `swapon` and `free` to verify that your new swapfile has been added:
+
+```console
+$ swapon --show
+NAME       TYPE SIZE USED PRIO
+/swapfile  file   4G   0B   -2
+
+$ free -h
+               total        used        free      shared  buff/cache   available
+Mem:            31Gi       3.6Gi        20Gi       233Mi       6.9Gi        26Gi
+Swap:          4.0Gi          0B       4.0Gi
+```
+
+{{< aside note >}}
+
+If you get an error saying that the `swapon` command was not found, try running
+it as `root` (using `sudo`). On Debian-based distributions the `swapon` command
+is not available to regular users.
+
+```console
+$ swapon --show
+bash: swapon: command not found
+
+# swapon --show
+NAME      TYPE SIZE USED PRIO
+/swapfile file   4G   0B   -2
+```
+
+{{< /aside >}}
+
+## Removing a swapfile
+
+{{< aside warning >}}
+
+Be careful that the swapfile isn't being highly used because once you run
+`swapoff`, it will dump the entire contents back into RAM and may cause you to
+run out of memory.
+
+{{< /aside >}}
+
+### Step 1: Disable/unload the swapfile
+
+```console
+$ swapon --show
+NAME       TYPE SIZE USED PRIO
+/swapfile  file   4G   0B   -2
+
+$ # the path to the swapfile I want to remove is `/swapfile`
+
+# swapoff /swapfile
+```
+
+### Step 2: Remove the entry from `fstab`
+
+Open `/etc/fstab` in a text editor and find the line matching the swapfile you
+want to remove, and delete it. For example:
+
+```text
+/swapfile none swap sw 0 0
+```
+
+### Step 3: Delete the actual file
+
+```console
+# rm /swapfile
+```
