<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</p>

<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>

<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 😎</p>

<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>

<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</p>
