v0.1 TLDR
This is the first weekly TL;DR, so this will probably set the standard, so I better do it good.
About the next CodeNight
This Codenight may be split into two halves, or maybe two groups: backend and frontend.
Backend
Backend-wise, we are gonna start a small FastAPI project built around a CRUD based history system.
The idea is to learn about Event Sourcing, JSON (and JSON Diffing), versioning (the same way that git works), CRUD and maybe see some index optimization at the end.
Overall, pretty solid concepts, a good foundation on a lot of things we are gonna be using in future projects.
If you want to be an early bird, finish the Initial Challenges and then start reading about CRUD (don’t worry, we will explain it anyways) and FastAPI, reading the amazing documentation. FastAPI documentation is so good it even explains Type Hints, a feature I personally abuse when coding (and you also should).
Frontend
Yes, Frontend, the “pretty” side of programming (until you get to debugging).
From centering a div to full fledged animations, this Saturday we will start learning React, a JavaScript Framework, but we wont be using JavaScript, we will use TypeScript, like the modern devs we are!
The plan is to start learning React using TypeScript, so if you want to catch up, also do the Initial Challenges (but with TypeScript), and look up what’s a Framework, what is React.js and why its the most used frontend framework in the current market (ask an AI or smth).
If you don’t know anything about web design (me last year lol) watch a very basic video about HTML and CSS, just to get the gist of it. We will probably not use pure CSS but use something like TailwindCSS, and for animations, we will probably use pure TypeScript or even the newer Motionwind, if we want to skip animations.
This half of the CodeNight will be handled by @Kevin-Ramirez127, as he is an experienced React dev.
Tech news
Copy Fail CVE Fix!
The Copy Fail CVE (Common Vulnerability and Exposure) (CVE-2026-31431), a local privilege escalation vulnerability (which means a random guy that got access to your server can get admin perms) was patched. Also, another LPE was discovered and patched, Dirty Frag CVE, similar to Copy Fail. Also, AMD patched some vulnerabilities in their kernel (Common AMD W).
IA in Linux Kernel
For the first time, AI generated code (a driver patch) was submitted for review to the Linux Kernel repository. The prom21-xhci driver, created with GPT-5.5 (Codex), to monitor temperature on an AMD chipset. It is currently under review.
Linux Updates!
Finally, Hyperland, a dynamic tiling Wayland compositor (lots of buzzwords, I know) finally released v0.55 with Lua configs and user-defined layouts. Manjaro 26.1 Preview launched, bringing GNOME 50 and Plasma 6.6. Also, NVIDIA Drivers update (v26.1)! Arch (btw) users, remember to update your kernel.
AI and Coding
Anthropic introduced a technique called “dreaming” for autonomous agents that lets the agent review its past actions and identify patterns to improve between sessions. Apple is reportedly preparing support to allow third party models to run power Apple Intelligence on iOS 27 (more unnecessary AI, yaaay), via a system called “Extensions”.
Agentic Coding Fuckup
A Cursor AI agent wiped PocketOS’s production database and all backups in under 10 seconds. This, once again, proves that fully relying on an Agent is stupid. Also, a broader pattern is emerging: “living off the agent” attacks are a new tactic hijacking enterprise AI systems, with the attack surface now moving inside the agent itself.
AI Coding Tools War
OpenAI Codex was tested on a real Python codebase and is being called the strongest Claude Code rival yet. Meanwhile, the AI coding workflow in 2026 is increasingly “agent-first”, with humans only reviewing code.
Infrastructure
PostgreSQL latest release brings native support for vector search to the engine, allowing for PostgreSQL use for RAG pipelines (we are definitely using PGSQL for our chatbot now).
Linus is still alive and thriving
Linus Torvalds (Linux and git creator) announced kernel 6.20-rc1, which finally strips out thousands of lines of code for obsolete floppy controllers and early 90s audio drivers. A long time coming.
That’s it for this week. There may be an update later if Codenight’s plans are changed.
