The Widgets, #XServer, #X11 window managers, and #Wayland compositors, which rely on everything else

We’ll try to make sense of all this, one thing at a time, with a logical and coherent approach.""

Participated in the Undefined hacker's festival and have a speech about my modded #Thinkpad X220.

Looks like I'm not only like to write enormously big blogposts. But also I'm able to make an enormously big presentations — my limit was 30 minutes and (looks like) my presentation was made for 1.5 hours, so @nikhotmsk stopped my endless speech

It was a lot of fun. First, I fixed the lamp, when came to the place. Then, I perform the presentation in the #Emacs through the VGA cable. Looks like it was unshielded, so a lot of cool video-noise from a DJ's devices were visible on the projector's screen during the presentation.

At least, I spoke something about WiFi drivers in #FreeBSD and about #Xserver before my time was out

Also, I met one of the fedifriends IRL. Sadly, I forgot to ask about his username, so if you are reading this — please mention me in the replies
