We all enjoyed it massively, even though we missed some particular plans.

 Lilka is an open hardware DIY console created in Ukraine. 
 It can be assembled from inexpensive electronic modules you can buy. 
 It is aimed at learning. Once you assemble it, you have a simple, yet powerful device with a lot of possibilities: 
 
 Run Nintendo (NES) games in emulation 
 Run DOOM 
 WiFi and Bluetooth 
 GPIO extension to connect more hardware…
I always thought it was ridiculous for the Internet graybeards, (for example, tenured computer science professors) to publish food recipes on their web pages. 
 Hereby I join their ranks!
I have seen more than enough bad recipes and screwed up baking (always a social event! must not disappoint others!) one time too many.

Mom lied in bed with the Little One, whom she was putting to sleep.
The Little One won’t fall asleep, as always: kept moving, playing and chatting with Mom. 
 Mom said: 
 — Your head must stay on the pillow! 
 Mom felt the need to add immediately: 
 — And the pillow must stay on the bed! 
 The Little One picked up another pillow, pressed it to the head, and raised on…

Thanks to the article “Your Makefiles are wrong” it really dawned on me that Makefile can run any interpreter, not just sh or bash: 
 
 The key message here, of course, is to choose a specific shell.
If you’d rather use ZSH, or Python or Node for that matter, set it to that. 
 
 Now, there are lots of articles and discussions purporting to discuss a “Python…

We’re the good guys.
We are always ready to sacrifice ourselves for all the good stuff we love in the world. 
 But we never get to enjoy our life! 
 It’s all their fault.

When Docker containerization was the new hotness, many old hands sysadmins were repulsed by it.
Not that the benefits were lost on them, but many aspects of system troubleshooting and maintenance were quite wacky.
A lot of trusty tools and mental models just had to be thrown away, with nothing, or cobbled together prototypes, to replace them.

It was a bit hard to find information about running model training on TensorFlow 2.x on multiple networked machines.
But I found enough and made it work, although it worked slower than single-node.

 I encountered a really easy and satisfying pixel art editor Piskel .
Used it, shown my little daughter, she instantly started creating her own art while really enjoying it.
(Before, she used Tux Paint a lot.)
I found Piskel while reading about Jugend Hackt , which is even more amazing.
For the last few weeks my family is up to our ears in maths exercises and brain teasers as my daughter has developed a big interest. 
 I am setting up a “newsletter” for puzzles.
Once in a few days I would send a few exercises.
Readers can send their solutions if they want, and I will mark them.
This would cost a few pounds per month.

Today during family dinner my kiddo started finger-counting.
I shared what I knew about a less popular system which allows counting to 12 on one hand: 
 
 Finger-counting systems in use in many regions of Asia allow for counting to 12 by using a single hand. The thumb acts as a pointer touching the three finger bones of each finger in turn, starting with the outermost bone of the…
Hi dear reader! 
 It’s April 5, 2022, and it’s day 41 of a full-scale military invasion of Ukraine.
The Armed Forces of Ukraine have just released Kyiv from semi-encirclement, liberated all of the Kyiv region as well as entire north of the country.
The previously occupied towns and villages are scenes of thousands of disgusting war crimes committed by the russian beasts.…
There are many potentially valid reasons you may want to be discriminate to countries on your personal computer or your network infrastructure.

Hello, the Free World! 
 Not every software geek blog starts with a post about a war.
A war which is bad enough to potentially become a world-ending nuclear world war.
I am honored by this. 
 Ukraine, my fatherland, is under an unprovoked and aggressive full-scale military invasion from Russia and its satellite Belarus.
You should know this by now, dear reader.
But Ukraine…
