This was on Mastodon... But should have been here too.
Jan Wildeboer on Mastodon (@jwildeboer@social.wildeboer.net)
Quite some years ago (2008), we brought the #OLPC AKA the 100$ laptop to Ethiopia as pilot. A surprising thing happened. The laptops were often without battery power in the morning. A thing that wasn’t anticipated. It had two reasons. One was the keyboard LED (it was removed in later series). It was used by the parents to have a light at home. The other was a bigger surprise. The parents used the mesh networking to discuss market prices for their produce. Fascinating.
With the mesh network built in to the OLPC, a local network that worked without needing a central access point (or the CPU), farmers used the chat function to compare prices offered for their produce and found out that merchants offered different prices. Draining the batteries while their kids were sleeping. This led to pressure on the merchants to pay better. The government was not amused. And mesh networking became a problem. Ultimately an inspiring story that was never told, IMHO.
Decentralisation remains an underexplored field in commerce and communication, IMHO. For obvious reasons. Capitalism relies on control and centralisation. Kind of a contradiction, IMHO. A reason why decentralisation and transparency are often touted as goals, but never really implemented.
(In a flat and open field, the mesh network of an OLPC, that didn’t need the CPU for transmitting network traffic, so still worked when the OLPC was „sleeping“ had a range of up to 4 kilometres)
(And thank you all for being kind and respectful in the comments thus far. The OLPC was (and is) a defining part of my private and professional life. I was only involved on the sidelines but I met people that ware so deeply invested into the ideas. Developers. Children. Teachers. But also aggressive opponents, lobbyists that did everything possible to kill the project. It teached me a lot. And I still feel sad it never lived up to its potential. Maybe it will. I'm still a believer)

Another video to help you get better at Algorithms. This one is called "Majority Element". It is an easy level array question but with two twists:
1. I have written it in Rust to make it more fun (and you can try in Python or whatever)
2. There is a very cool and fast solution for this problem which is very difficult to find if you have not seen it. On the 2nd step, I show that one; called "voting algorithm".

Top Algorithm Interview Questions Explained - Valid Parentheses - Stacks, Easy
In these series I'm going to solve many Programming Interview questions related to algorithms and explain my thought process. I will try to be detailed and show you how a programmer thinks when confronted with such questions.
This one is about Stacks and is Easy:
Given a string s containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid.
An input string is valid if:
- Open brackets must be closed by the same type of brackets.
- Open brackets must be closed in the correct order.
- Every close bracket has a corresponding open bracket of the same type.

Unleash Your Inner Geek: Crafting your own Unix Command! Program your own 'who' and 'users'.
Ever wondered how the Unix wizards conjure up their spells? Join me on a thrilling journey as we decode the magic behind the who and users commands. This isn't just another tutorial; it's your gateway to becoming a command line sorcerer on Linux, BSD, or Mac systems.
‍ We'll start by unraveling the mysteries of the UTMP unix version 1 format on OpenBSD, guiding you through the arcane process of information extraction. Then, we'll peek into the very source code of the users command, revealing secrets that have been closely guarded by the Unix Elders.
By the end of this adventure, you'll not only be versed in the ancient UTMPX texts but also be ready to craft your very own users or who commands. Imagine creating a bespoke tool like is_logged_in, which can divine the presence of a user with a simple 1 or 0.
Prepare for that 'Eureka!' moment, as the curtain lifts and the commandline's enigmatic workings become clear. If you're armed with basic programming knowledge, this video will elevate your skills to mystical heights.
So, are you ready to wield the power once held by the Unix Elders? Let's embark on this quest for command line enlightenment together!

Hetzner (like many other providers) do not provide #OpenBSD machines.. but there is a nice #syadmin trick to install your beloved OS over whatever they provide. In this video we will see how you. In short:
1. Create your #GNU / #Linux machine
2. Login, wget & dd the IMG
3. Reboot in Console and install using network installation (say http packages)
4. Reboot in your new OS
5. Have fun.

Have 10mins to deepen your understanding of #Unix like systems?
Check the utistd.h page. This is the header file that provides access to the POSIX operating system API. Even a quick browse can show you how your program talks with your OS.
https://en.wikipedia.org/wiki/Unistd.h
For example whenever your program needs a higher privilege (or to act as another user), it calls `setuid` for that. Or starts with `sudo/doas` to have a higher access but calls `setuid` to become "nobody" in most of its life cycle.
If still have a click to spare, check the setuid.h on #OpenBSD man pages:
https://man.openbsd.org/setuid.2
in most cases OpenBSD man pages are the best references you need to understand the OS.

When learning the programming, seeing a mature program with all the loops and conditions might look confusing. You might wonder how the programmer has coded all of this?
Here I'll show you how a programmers might solve a challenge in its most basic / simple form and then add loops and conditions to make it more general / userful.
