π Check out this trending post from Hacker News π π Category: π Key idea: Hey all. TinyKVM was open-sourced this february and since then Iβve been working on some things that are very much outside of the scope of the original implementation. Originally, it was intended to be for pure computation (and that is very much still possible, and is the default), but makes it hard to use TinyKVM outside of specialized use-cases. So, Iβve relented and implemented limited support for running unmodified executables in TinyKVM. Specifically, run-times like Deno, Python WSGI and similar run-times like Lune.I would like…

π Read this must-read post from Hacker News π π Category: π Key idea: Pico-Banana-400K is a large-scale dataset of ~400K textβimageβedit triplets designed to advance research in text-guided image editing.Each example contains: an original image (from Open Images), a human-like edit instruction, and the edited result generated and verified by the Nano-Banana model. The dataset spans 35 edit operations across 8 semantic categories, covering diverse transformationsβfrom low-level color adjustments to high-level object, scene, and stylistic edits. Feature Description Total Samples ~257K single-turn textβimageβedit triplets for SFT, ~56K single-turn text-image(positive) - image(negative)-edit for preference learning, and ~72K multi-turn texts-images-edits for…

Hereβs what youβll learn: At first, all of this AI stuff felt exciting. I was curious to try everything (I was actually one of the few naive people who thought the Rabbit R1 was a good product before it eventually launched), and for a while, it felt useful. But over time, I realized AI isn't just affecting smartphones; it's creeping into all consumer tech, often making products worse instead of better. What started as something promising has become a constant stream of gimmicks and distractions I didn't ask…

I've allowed anyone to make "cameos" using my face. (You don't have to do this: You can…

Key idea: Saturday. October 25, 2025 - 15 mins Part 1 β From power button to the kernelβs first breath You press the power button. A second later a wall of text scrolls by, or a logo fades in, and eventually Linux appears. What happens in between is not magic. It is a careful handshake between tiny programs and a very literal CPU. This part follows that handshake until the very first line of C code inside the Linux kernel runs. The very first instruction When power stabilizes,…

In the spring of 1996, when the journal was the object of an enthusiastically publicized hoax by the physicist Alan Sokal, its survival seemed a bad bet. You published an essay arguing that gravity is a βsocial and linguistic construct?β Really? The mainstream media, hitherto unaware of the existence of this very little, very marginal magazine, were uncertain what exactly they were mocking. Was Social Textβs foolishness postmodern? Left wing? Cultural? Academic? They were certain, however, that what they smelled…

π₯ Read this insightful post from Hacker News π π Category: π Hereβs what youβll learn: A while back, I worked on a RISC-V-based userspace simulator for fun. In doing so, taught myself a lot more than I wanted to know about what happens in-between when the Kernel is asked to run a program, and when the first line of our programβs main function is actually executed. Hereβs a summary of that rabbit hole. In the beginningβ¦ First question: When is the OS kernel actually asked to run any program? The answer, at least on Linux, is the execve system…
