A system to reject phone calls from my laptop

This post is about a system we devised and set up at home for me to be able to reject all the annoying phone calls I receive during the day from my laptop, without having to go pick up the phone. If you are also working from home like I do (yes, this is another cool option we have at Igalia!) you might find this hack useful. 😀

Hair simulation with a mass-spring system (punk’s not dead!)

Hair rendering and simulation can be challenging, especially in real-time. There are many sophisticated algorithms for it (based on particle systems, hair mesh simulation, mass-spring systems and more) that can give very good results. But in this post, I will try to explain a simple and somehow hacky approach I followed in my first attempt to simulate hair (the mohawk hair of the video below) using a mass-spring system.


 

The code can be found here: https://github.com/hikiko/mohawk

A short OpenGL / SPIRV example.

It’s been a while since Igalia is working on bringing SPIR-V to mesa OpenGL. Alejandro Piñeiro has already given a talk on the status of the ARB_gl_spirv extension development that was very well received at FOSDEM 2018 . Anyone interested in technical information can watch the video recording here: https://youtu.be/wXr8-C51qeU.

Winnie: a framebuffer window system

A few weeks ago, I started a minimal window system, which performs software rendering on the linux /dev/fb0. My aim was to learn some systems programming and familiarize myself with concepts like event and device handling, memory management, window management, drawing on the framebuffer, IPC mechanisms etc (and certainly not to create a full linux window system! :)p) I call the program winnie and the code is available on github here: https://github.com/hikiko/winnie/tree/winnie.clients-as-plugins, https://github.com/hikiko/winnie and lp.

The program is not finished yet and I don’t know if I ever finish it, since I came up with new project ideas again.. Nevertheless, you can see some videos of the development stages below if you are interested (most recent first):

A virtual keyboard

Some days ago I came up with the idea of a keyboard that can be used without having to type the letters. The user just stands in front of a camera and scrolls the letters by moving his head or hands to the appropriate direction…

And here it is:
