There are sex predators walking on the sidewalk. You might fall while trying to jump over a canal. I’ve even heard about shootings and knife attacks. Streets are dangerous, so why not pass a law stating that everyone stepping outside their home must show ID and fill out a form explaining where they are going, why they are going there, and for how long? This would surely make our streets much safer - although, of course, things could still happen. And naturally, people under 18 wouldn’t be allowed on streets the state considers harmful. Silly? Totalitarian? Non-functional? Counter-productive? Yes to all of the above. And on top of that, it wouldn’t even help much with crime rates. Violent crimes still happen in prisons, where everyone is known, constantly watched, and prevented from carrying anything remotely dangerous. Now think about the internet and the laws currently being proposed. Age restrictions. Identity checks. It’s not a perfect analogy, but both point in the same direction. Once you allow the state to “age-check” you on porn sites (read: identify everyone, record everything they do forever, and share it with whoever they want), why wouldn’t they require age checks on Reddit (which is full of NSFW content) or identity verification on GitHub (which hosts sensitive code)? But does this mean anyone should be able to access anything on the web? In my opinion, no. Let’s return to the street analogy. When you go to a bar, you show an ID and get your drink. The bartender doesn’t copy your ID, doesn’t sell your information, doesn’t record when you arrived or left, doesn’t log how many shots you had (or which brand), doesn’t take your photo, and certainly doesn’t report your presence to anyone. Online age verification should work the same way. A zero-knowledge proof that confirms your age without revealing anything else to the server. This technology is still relatively new, and we need to give it time to mature before forcing everyone to adopt a specific solution. #privacy #zkp #humanrights npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi dude npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi Both Azure (https://www.githubstatus.com/) and GitHub (https://www.githubstatus.com/) are having issues.

But should have been here too. Jan Wildeboer on Mastodon (@[email protected] ) 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) https://nostrcheck.me/media/c28aece562af2d5d33e79775d29fe6026023e55e641bfc03e138b2066ed9113a/d0901af3068ba09dd79091b721f4aa03007e8e66e6946760591b06d56ee915ce.webp npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi GM Nostr & Happy Programmer Day...

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?

It can parse the classic UTMP files which #OpenBSD still uses to keep track of logged in users and such. https://crates.io/crates/utmp-classic in this version I upgraded the zerocopy to 0.7 series and it needed some changes because of the new zerocopy::Ref . npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi 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. Here is my video of above steps... with some more info, discussion and fun :) https://youtu.be/vSVQXWbnNgY npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi Reminder: #Nostr is decentralize. Change your client, start your relays. Keep it decentralized. Decenteralization is not only a tech concept, but a metnal one. Search for clients and try them. Contribute and have fun. npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi 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. #BSD #Linux npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi I was sending a minor PR to the uutils / #coreutils project regarding a breaking test on #NetBSD and thought its a good opportunity to record a video and: - talk about the uutils/coreutils which is a rewrite of coreutils in Rust - show the #NetBSD env and do some coding in it - Show the flow of sending a PR on #github https://youtu.be/5JcaQWGMRVE npub1c29weetz4uk46vl8ja6a98lxqfsz8e27vsdlcqlp8zeqvmkezyaqlupw98 Jadi https://void.cat/d/RtzW6jTikT1yvnyfot1KTg.webp Everyone else: @npub1sg6…f63m is not on blah blah...
