Recently xssfox posted that xrandr is able to do incredible things, for example render the image diagonally on the screen.
What if you could do the same, but automatically, in real time?
You saw a computer monitor on a pivot that levels the displayed output when the monitor is turned. It's not much different than what smartphones do when set to alternate between the portrait …

Quite recently Dragit, the local file sharing app written in Rust, GTK and libp2p, was positively reviewed and joined Flathub. On that occasion let's see what is Dragit and why it can be a useful tool.
If you ever tried to send a file from one computer to another, perhaps you've noticed that this task is more …
Read more...In the previous post The Ulam spiral in Rust I described application that generates prime numbers spiral. I have chosen gtk-rs to write the user interface, because of the pretty good documentation and examples in the repository. If something is not documented there, you can easily check the original Gtk library written in C, which was a base for the Rust version. Also, I just like Gtk, no big story. …
I'd like to share some thoughts about a specific mathematical phenomenon related to the prime numbers and tiny piece of software to generate visual representation of it.
For the long time I was curious about the LEGO Mindstorms EV3 set, because it's the low entry toolkit for beginning your journey with robotics. What I didn't know is that Mindstorms contains ARM-based computer device, which can run Linux without any complications and make your own experiments with servo motors and sensors.
I decided to build a robot that is capable of driving around and making 2D scan map …

If you are playing with event sourcing, there is a good chance that you have topics that have very long retention time - maybe months or more. It means that the message once pushed …

My goal was to implement Huffman coding algorithm as in this example: https://www.siggraph.org/education/materials/HyperGraph/video/mpeg/mpegfaq/huffman_tutorial.html …

Yet when applying HTTP for purpose of API calls in frontend-backend or backend-backend calls you face some fundamental (well, not so fundamental in the live-death sense, but still) questions.
In my …

Recently I begun to play with Rust - a promising, multi paradigm programming language, that looks similar to C family at first glance, but turns out to be something way more interesting.
At the same time I was obsessed with TDD (test-driven development) methodology and wanted to write used it in a Rust project. However, I encountered some problems with organizing the test directories in my Rust. We'll be investigating …

Check what we have created on Hackaton Kulturalny in Warsaw!
This is something that we made for our friends from PAN Biblioteka Gdańska (library of Gdańsk). It's an internet bot used to fish out some interesting things from library, analyze them using simple machine learning algorithm and publish to Twitter and Facebook.
Check them!
