What I learned building a job-description importer that needs a manual fallback

Most resume-tailoring products begin with the same input: a job URL. That sounds simple until the URL belongs to a site that renders content with JavaScript, blocks automated requests, requires authentication, changes its markup, or hides the useful description inside an embedded application system...

I Built Neva, a Small Lattice Analysis Toolkit in Python

https://github.com/black-210/neva I started working on a small project called Neva because I wanted to experiment with lattice mathematics without starting with a huge framework. The original idea was pretty simple: Take a lattice, enter its basis vectors, and let the program show me what is happ...

Preventing lost updates in Symfony APIs with ETags and Doctrine

There is a concurrency problem in APIs that is easy to miss. Two clients read the same resource: Client A -> GET /documents/42 Client B -> GET /documents/42 Both receive the same version. Client A changes the title and saves it. Then Client B, still working with the older represent...

OpenAI's New Security Controls Are an Admission, Not an Innovation

An incident happens, a vendor ships a fix, and everyone calls it "proactive security." It isn't. Let's just say that out loud. When a frontier AI lab has to bolt on guardrails after a model already went outside its intended boundaries, that's not a feature launch. That's an incident report with a m...

Claude Opus 4.6 Shows Why Old Models Need Patch Windows

Educational tools deserve production-grade polish

Educational software has a look. You know it the second you see it: clunky, dated, built like the content was the only thing that mattered and the experience was an afterthought. That reputation is mostly earned — and I think it quietly sabotages learning. So with AlgoVerse, I refused to accept it....

Reordering an overflowing job queue does not shrink it. Splitting it does.

Background I run about 20 small sites and update them automatically. A batch runs four times a day, decides which sites have work due, and then does only that work. The decision itself lives in one script, whats-due.js. Its only inputs are tasks.json (task definitions), state.json (run s...

I built Kintara because apparently having too many hobbies eventually leads to building your own document management system.

Kintara is a self-hosted document library and reader that runs in Docker and watches a folder you already have. Drop PDFs, Markdown, or text files into the directory and it indexes them automatically, extracts searchable text and metadata, generates thumbnails, and makes the whole library available...

Free AI Tokens Are a Trap: An Opinionated Cost Gate for Model Experiments

Free AI tokens are a trap, and teams that treat a free quota as genuinely free pay later in migration and rework. A free allowance only helps when paired with a hard kill switch that stops an experiment the moment it exceeds a budget you chose in advance. This article argues that position, then show...

LLM Model Fingerprinting: Verify What Your AI Gateway Is Really Serving

Your prompt can ask a model what it is. Your production system should not trust the answer. A model can say it is GPT, Claude, Gemini, Llama, Qwen, or anything else. That does not prove what is behind the endpoint. A gateway can route requests silently. A provider can change a default model. A fa...

Token Budget Alarm on a Free Server

A free model quota is a budget, not a gift. You should treat it like one if you plan to build anything on top of it.
