From Pixels to Calories: Mastering Precise Food Estimation with Vision AI

We’ve all been there: staring at a delicious plate of Carbonara, trying to log it into a fitness app, only to realize the "standard serving" is wildly different from what’s actually on the plate. Most Vision Multimodal apps fail because they can identify the what (it's pasta!) but fail at the how much (is it 200g or 500g?). In this guide, we are bridging that gap by building a high-precision foo...

Deep Dive into XZ Utils Backdoor - Columbia Engineering, Advanced Systems Programming Guest Lecture

I did not find this particular lecture posted here before and it's the best one I have seen so far that covers what became the most famous backdoor of recent history - all in well under an hour net duration. It is easily distinguished from all the others as it properly also on the second part, i.e. how the exploit worked, including with a demo and so not "just" how it got sneaked into th...

A 350-Line GLSL Shader Playground in the Browser — WebGL Init, Line-Number-Aware Errors, and URL-Hash Sharing

A 350-Line GLSL Shader Playground in the Browser — WebGL Init, Line-Number-Aware Errors, and URL-Hash Sharing

Sometimes you want to try a shader without spinning up Shadertoy, without a build step, without anything. Just a textarea, a canvas, and a refresh-while-you-type loop. This is that page: ~350 lines of vanilla JS, a fixed full-screen-quad vertex shader, and a fragment shader you edit live. Compile errors land back in the UI with line numbers; the URL hash round-trips your source so links shared on...

How to Migrate a Production Stack to a New Region Without Downtime

Last spring I moved an entire production stack — database, object storage, app servers, mail — from one cloud region to another. Different continent, different provider, same users. The plan looked clean on paper. The execution? Less clean. If you've ever tried to physically relocate a running system, you know the feeling. Stuff that worked locally suddenly doesn't. DNS lies to you. Half your use...

Foreboding AI, One Year Later: What Are We Really Building?

A year ago, I wrote Foreboding AI: The Inevitable Collapse We’re Funding Ourselves At the time, my concern was that we were paying for the very systems that could eventually replace us. We were subscribing to tools that learnt from our prompts, our corrections, our habits, our work, and our impatience. A year later, I still think that concern was valid. But my worry has changed shape. It is no...

"When 'Control request timeout: initialize' actually means SIGKILL: Claude Code CLI OOM inside Celery"

A production Celery task in Codens Green started returning this, intermittently, only under real load: Control request timeout: initialize The string is suspiciously specific. It looks like the kind of message you would see if Claude Code CLI's MCP initialization handshake had timed out on the other side of a pipe. That is what it sounds like. That is not what it was. The task is analyze...

I Queried a Blockchain Like a Database and It Kind of Broke My Brain

Week 2 of #100DaysOfSolana: on reading public data, comparing accounts to tables, and the moment the "everything is public" thing got real. Let me tell you about the exact moment week 2 of this challenge stopped feeling theoretical. I had just written my first getBalance() call. Simple stuff paste an address, get a number back. And then I thought: what if I paste someone else's address? So I...

How Optimization Search Works — From Hill Climbing to Genetic Algorithms

Optimization is not just about finding a good answer. It is about finding a better answer than the one you have now. The hard part is knowing whether your current “best” is truly best, or just locally good. Core Idea Optimization is the process of improving a solution according to some objective. You start with a candidate solution. You measure how good it is. Then you search for ...

How Neural Networks Work — From Perceptrons to Backpropagation

A neural network is not magic. It is a system that transforms input into output through layers. The real question is: How does that system learn from mistakes? Core Idea A neural network takes data, passes it through connected layers, and produces an output. During training, it adjusts internal values so future outputs become better. Those internal values are mainly weights and bi...

Satellite maths meets reality

This is an image a friend took of a Comet (C/2025 R3 PANSTARRS) that is visiting the night skies currently. It is a 30 second exposure and the Nikon camera had a bad internal clock so it was timestamped at an uncertain time. The exact spot was known. The challenge: can we reconstruct the same image, with the stars in the same place, identify the exact time it was taken and will everything match...
