<h1 id="the-magic-of-wake-on-lan">The magic of Wake-On-LAN</h1>
<p>
  Years ago, some good friends of mine gifted me a Raspberry Pi 4 with 2GB of
  RAM for my birthday. It’s hands down the most thoughtful gift I’ve ever
  received, perfectly matching my hobbies. They were lucky to even find one
  during the chip shortage! I initially used it as a VPN server with WireGuard
  and played around with Pi-hole for network-wide ad blocking.
</p>
<p>
  Eventually, I got into cloud computing and started hosting multiple services
  on a VPS I rent from MVPS. This VPS, with its 4GB of RAM, currently runs
  several of my daily-use services like Gitea, Searx, NTFY, and more. Although
  the Raspberry Pi could theoretically handle these services, its 2GB of RAM
  limited simultaneous operations.
</p>
<p>
  One day, it hit me: why not use the Raspberry Pi for a simpler project like a
  Wake-On-LAN (WOL) server? It requires minimal resources and just needs to stay
  on and send WOL packets. The Raspberry Pi is connected via Wi-Fi to the same
  network as my laptop. Normally, waking up my laptop with WOL would require an
  Ethernet cable connection to the router, but I connected one end to the Pi and
  the other to the laptop.
</p>
<p>
  I started with a simple shell script using etherwake, a command-line tool to
  send WOL packets. After enabling WOL in my laptop’s BIOS and confirming it on
  the OS using ethtool, I could easily wake my laptop remotely using a Termux
  shortcut on my phone, which SSHed into the Raspberry Pi to execute the
  etherwake command.
</p>
<p>
  Though this setup worked perfectly fine, I wanted to make it even better.
  Initially, the Raspberry Pi only ran SSH and executed a command to wake my
  laptop. So it wasn’t really a WOL server. After some research, I found Flask
  and created an actual WOL server. This server had routes, authentication,
  logging, rate limits, and more to ensure robustness and security.
</p>
<p>
  What makes my Flask-based server so cool is its dynamic nature. I can
  configure a .env file with multiple device MAC addresses, allowing numerous
  routes for different devices. For instance, I have LAPTOP_MAC=“itsmac” and
  DESKTOP_MAC=“itsmac”, enabling me to wake them via HTTP requests at
  /wol/laptop and /wol/desktop, respectively.
</p>
<p>
  One open-source application that fits my use case is HTTP Shortcuts from
  F-Droid. After configuring a specific route, I can turn it into a widget on my
  home screen. This way, I can wake my laptop up with just a tap! Plus, I use
  dynamic DNS, so my Pi is accessible from anywhere.
</p>

</p>
<p>
  I would suggest anyone to take a look at my project’s repo and if they find
  that it fits their needs, use the setupSingleBinary.sh script to grab the
  latest executable. The repo is over at

<title>WebCall</title>

<h1 id="webcall">WebCall</h1>
<p>One of the simplest ways to host a “telephony” service is to use webcall.</p>
<p>
  Like with emails, you can use any webcall server to communicate with any other
  webcall server. Meaning that if for example you register a number with
  https://timur.mobi/ which is the default public server you can still make a
  call to someone who has registered a number with https://talk.konsthol.eu if
  you know their number by replacing the server address field in the dialpad
  icon.
</p>
<p>
  All calls are encrypted and the server does not have access to the content of
  the calls. That is because the server uses webrtc and tries to make peer to
  peer connections.
</p>
<p>
  There is also an integrated TURN server which is used if the peers can’t
  connect directly but if the connection is made though that then no video
  transmission is possible. I suspect that this is a limitation of the TURN
  server used in webcall because in jitsi meet which uses coturn instead of
  pion, it is always possible.
</p>
<p>
  Another differentiation of the two services is that in webcall no more than 2
  people can join a conversation, which is more similar to how a regular
  telephone call behaves.
</p>
<p>
  Also there is currently no functionality to block a number as far as I can see
  but it should be fairly easy to figure out the public ip address and block it
  like that.
</p>
<p>
  You should give it a shot and see if it works for you. The source code is at a
  link over at

<title>wpgtk is just more convenient</title>

<h1 id="wpgtk-is-just-more-convenient">wpgtk is just more convenient</h1>
<p>
  Pywal is a simple KISS principled python application that extracts colors from
  an image and creates a color pallete to theme different programs
</p>
<p>
  By default there are some templates that are stored in its .cache directory
  and there is an option to create new templates in its .config directory.
</p>
<p>
  I found it to be simpler to create every template with wpgtk and store it in
  its templates folder in .config because there it also utilizes symlinks to its
  respective files and thus you can have every program’s file to manage in one
  place.
</p>
<p>
  Moreover wpgtk conveniently stores each created colorscheme in a schemes
  folder in .config and along with that every wallpaper used as a symlink to the
  actual wallpaper in a wallpapers folder.
</p>
<p>
  It also has a gui interface but I never really found a use for it as one can
  easily perform every needed action using just the cli.
</p>
<p>
  After creating a script to be run after every use of the program to theme
  application that need third party scripts like telegram and qutebrowser the
  process of switching colorschemes on the fly becomes easy as pie and fast as
  fuck 🤫
</p>
<p>
  Just give it a shot! Maybe I’ll upload my postWPG script in my gitea instance
  sometime soon and create an actual tutorial on how to use wpgtk

<title>Awesome file sharing tool</title>
<link>https://konsthol.eu/log/easy_file_sharing-12-09-2021.html</link>

<h1 id="awesome-file-sharing-tool">Awesome file sharing tool</h1>
<p>
  Croc is one of the best easy to use file sharing cli tools I came across and
  only recently discovered how easy it can be to self host your own relay.
</p>
<p>
  Croc as far as I understand needs an intermediary to staple as it says the
  connection between two computers. If I grasp the concept correctly if two
  computers can both connect to a third one then a connection between them can
  be established. The files sent over don’t get first uploaded to the third one
  and then downloaded to the second but somehow get uploaded and downloaded
  simultaneously.
</p>
<p>
  I’ll have to further read about that but in short if you have a computer like
  a server with a static ip that is easily accessible from the internet then
  because of the great job the author did you can host a relay simply by typing
  the command
</p>
<blockquote>
  <p>croc relay</p>
</blockquote>
<p>
  which will by default use the ports 9009-9013 but you can specify your own
  with the –ports arguement like
</p>
<blockquote>
  <p>croc relay –ports 1111,1112</p>
</blockquote>
<p>
  Then if you make that into a systemd service (which I won’t be covering just
  yet cause I don’t really understand them and only make them by copy pasting
  basic templates 😐) it’s basically a set and forget kind of thing and you can
  now send files to anyone in any operating system by using croc by typing
</p>
<blockquote>
  <p>croc –relay “your.domain:9009” send [file]</p>
</blockquote>
<p>and the recipient can download it by typing</p>
<blockquote>
  <p>croc –relay “your.domain:9009” [code]</p>
</blockquote>
<p>
  This is super useful cause there was a time when the public instance was down
  and I couldn’t send files when it was just so easy to not be dependent on the
  public instance in the first place.
</p>
<p>
  You should definetely read more about it on Croc’s github page and set up your
  own relay asap 😎
