I'm trying to understand what a Kernel and an Operating System (OS) actually are.

I've already asked several AI tools, but their explanations are either too technical or still confusing for me.

Can someone explain both in very simple words, maybe with a real-life example or analogy, so I can clearly understand.

Please explain it like you're explaining it to a beginner with no technical background.🥺

Perdition-OS is a complete overhaul of Tutorial-OS where I took portions of the parity C and Rust code to generate a clean split in responsibilities and a well defined FFI layer. The Vertical HAL architecture has been massively expanded. Watchdog implementation, SMP with accessing all cores on the system, Work stealing scheduler, separation of kernel mode from user mode apps, PDF renderer, PNG and JPEG rendering, FBX rendering (partial implementation based on concepts seen in UFBX), user mode apps can only be written in Rust and a topology system for being able to view what hardware exists and how they function.

The UI is still early and subject to change, however, I personally really like the design as it gives detailed information that is rarely exposed.

The rationale for this is that there is a clean separation between systems and should be a project that will help guide someone towards building an OS of their own. I focused more on the "boring" apps because to me, it is something that would make the average person care about the OS for their SBC and give them a starting point for forking and making the OS handle the things they care about.

Hi, I recently installed linux mint on my laptop, and I've got to say, it's absolutely fascinating. I can literally allocate memory to swap, download apps from terminal etc. I have never been this guinely interested in something.

I am currently learning from Labex some basic commands. Does someone have any suggestions?

Pureunix running on my macbook thru QEMU

I’ve been quietly working on a hobby operating system called PureUNIX for the past few months, mostly as a way to learn how Unix-like systems actually work under the hood.

This week I finally hit a milestone that felt worth sharing.

The latest version now has a real Unix-style process model with protected user mode, per-process virtual address spaces, fork(), exec(), and waitpid(). Seeing a process fork, replace itself with a new ELF image, and return control to the shell was one of those “okay, this actually feels like an operating system now” moments.

A few other things it has at the moment:

• EXT2 + FAT16 through a VFS
• Interactive shell with pipes and redirection
• A small vim-like editor
• User accounts and login
• Around 215 regression tests covering everything from the VFS and permissions to symlink loops, large files, and process management (currently all passing)

It’s written almost entirely in C99 with a bit of x86 assembly and targets 32-bit x86. I know it’s still missing plenty of things—preemptive scheduling, networking, mmap(), and lots more—but getting to this point has been a ton of fun.

I’m posting here because I’d genuinely love feedback from people who know Unix well. If you see something that’s particularly Unix-like, or something that makes you think “that’s not how Unix would do it,” I’d love to hear it. Those discussions are honestly the most valuable part of building a project like this.

Hey guys im 17

i like to do simple eposrts games like cs2 and gta and valorant but i also like a clean minimal desktop vibe and smoothness as im going into engineering at the moment please recommend me what os windows or Mac or if its worth learning about linux ?

How can one reliably extract Windows a11y tree, that is not just at the desktop level, but also inside app whatever is rendered as a part of the UI?

More over, I intend to safely interact and manipulate with that tree regardless of its size. I do understand that a11y tree sometimes if too big can hung up the system by blocking thread, but there must be some optimised, reliable, way to retrieve, access, and manipulate the a11y tree?

Bon, je vais être direct parce que ce sub c’est justement fait pour ça.
Ça fait un moment que je m’intéresse aux outils numériques pour la différenciation pédagogique. J’en ai testé pas mal. Moodle où il faut s’arracher les cheveux pour monter un parcours adapté, des plateformes payantes qu’aucun établissement ne validera jamais en budget, des outils soi-disant intelligents qui balancent les mêmes exercices à tout le monde dans l’ordre alphabétique.
Il y a deux semaines je suis tombé sur open.mentivisos.com. C’est gratuit. Pas un essai de 30 jours avec des fonctionnalités bloquées ensuite. Gratuit.

Ce que ça fait concrètement :
Tu construis un parcours avec une vraie logique de progression, pas juste une liste de ressources empilées. Il y a un diagnostic en entrée qui repère où en est réellement l’élève, pas où il devrait théoriquement en être selon le programme. Les modules sont pensés en écarts à combler, pas en contenu à dérouler. Tu peux l’utiliser pour toi-même si tu prépares un cours ou une remédiation, ou pour construire un parcours différencié pour une classe hétérogène.
Ce que ce n’est PAS : un ENT, un outil de gestion de classe complet, une usine à QCM. Ça ne remplace pas Pronote et ça ne prétend pas le faire.
C’est un outil de structuration pédagogique individuel. Pour toi, pour une séquence, pour un groupe d’élèves en difficulté que tu veux accompagner sans recréer dix fiches différentes à la main.
Je l’utilise depuis deux semaines pour monter un parcours de remédiation différencié sur un chapitre où j’ai un écart de niveau énorme dans la classe. Ça m’a évité de passer mon dimanche à bricoler trois versions du même cours.

Dear Cybersecurity engineers, I am a novice to Cybersecurity and I'd like to know what OS is the best for practicing and doing Cybersecurity in action (blue team), I currently have Windows 11, but I am not sure if that's the best option. I don't want to wipe my PC so I will be running the OS on my VM. Any recommendations for an OS that can run on a VM? And my PC has 32GB of RAM.

Thank you for your advice.

Im not a massive tech person but know a little. But wanting to move my operating system from cdrive which is a hdd to another drive which is an sdd.

Conventional OSes are built for apps, while future tenants of OS might be AI agents.

This project, AOHP (Android Open Harness Project), aims to reengineer Android with native support for AI agents.

Remarkably, it introduces the idea of "user-defined apps", in which the apps are automatically generated based on personalized user intents rather than predefined by developers. The functions of generated apps are backed by agents under the hood.

I think it may change the role of developers. Perhaps in the near future, instead of developing apps, developers should work on something lower-level, such as widgets, services, capabilities, skills, etc. All frontend apps are generated from the low-level components. Not sure whether it will be a good thing for developers, and how the monetization may work...
