+
+## 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
+
+```bashsession
+$ 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:

+
+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]
+

+
+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:
+
+[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].
+
+[math-challenge-caching]: https://github.com/rebane2001/txnor-server/blob/26c7c279b0b4668c8a3b061692d83c507aeac7c5/sex.py#L137
+
+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].

+
+This is a step-by-step tutorial on how to create or remove a swapfile on a Linux
+machine, and whether you should create swap space in the first place.
+
+Also included is the most correct `fstab` entry: most articles get this "wrong"
+(but it doesn't actually matter).
+
+<!--more-->
+
+## 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.
+>
+> - It’s better to swap out memory pages that have been inactive for a while,
+>   **keeping often-used data in cache**, and this should happen when the server
+>   is most idle, which is the aim of the Kernel.
+>
+> - Avoid setting your swap space too large if it will result in prolonging
+>   performance issues, outages, or your response time (without proper
+>   monitoring/alerts).
+
+[always-add-swap]: https://haydenjames.io/linux-performance-almost-always-add-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 path="include/bashsession.md" markdown=true >}}
+
+### Step 1: Create the file
+
+The first step is to allocate the file.
+
+```bashsession
+# 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:
+
+{{< table >}}
+| GiB | MiB         |
+|-----|-------------|
+| 1   | count=1024  |
+| 2   | count=2048  |
+| 3   | count=3072  |
+| 4   | count=4096  |
+| 8   | count=8192  |
+| 16  | count=16384 |
+{{< /table >}}
+
+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:
+
+```bashsession
+# 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:
+
+```bashsession
+# 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):
+
+```bashsession
+# 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`. This is actually a result of
+[cargo culting](https://en.wiktionary.org/wiki/cargo_culting). On Linux, the
+`sw` option (and the [options specified by the commonly used
+`defaults`][fstab-defaults-man]) [isn't valid for `swapon` and is
+ignored][swapon-options-source]. 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).
+
+[fstab-defaults-man]: https://man.archlinux.org/man/fstab.5#The_fourth_field_(%3Ci%3Efs_mntops%3C/i%3E).
+[swapon-options-source]: https://github.com/util-linux/util-linux/blob/2ea397239683270a0fc8cd3b72ed5457f52dbda8/sys-utils/swapon.c#L699
+
+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.
+
+```bashsession
+# swapon /swapfile
+```
+
+### Finally: check the swap status
+
+Use `swapon` and `free` to verify that your new swapfile has been added:
+
+```bashsession
+$ 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.
+
+```bashsession
+$ 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
+
+```bashsession
+$ 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
+
+```bashsession
+# rm /swapfile
+```
+
+## References
