Let me show you something cool. This two-minute video was built by Claude Code from a single prompt. Okay — one prompt and about thirty follow-ups. And then twenty more after Claude Code fumbled a git command and wiped out half of my video-editing ma...

Dependabot has a default behaviour that doesn't scale well: one pull request per outdated dependency. For a repository with a hundred dependencies, a run generates dozens of individual PRs. Most are low-risk patch bumps a developer approves without r...

A SOC analyst's notes on going from "I want to learn async" to a working tool that other analysts can clone and use. TL;DR I'm a SOC analyst learning Python and built IOC Hunter — an async tool that takes a chunk of text (phishing report, log dump, S...

I've spent 25 years building, breaking, and scaling production infrastructure — long enough to watch "DevOps" go from a conference buzzword to a thing companies now rent by the month. That shift is real, and for a lot of teams it's the right call. Bu...

This is the one post in the series you do , not just read. By the end you'll have a single Telegram topic where you type a message and a coding agent answers and drives a tmux pane on your own box. That's the entire goal, nothing more. Memory, monito...

You add TypeScript to a project, turn on strict , fix every red squiggle, and feel safe. Then a third-party API quietly changes a field from a number to a string, your app explodes in production, and TypeScript never said a word. That gap surprises p...

Startups make two monitoring mistakes. The first is spending $500/month on Datadog before they have paying customers — full-stack observability for a service that handles 200 requests per day. The second is spending $0/month on nothing until a produc...

I have been working on a PostgreSQL compatible database system in Rust and recently made a couple of changes that significantly reduced unnecessary memory allocations. The first change was in the lexer. Originally, identifiers were stored as String v...

At 2am on a Tuesday, an IP address change in Microsoft infrastructure silently broke our entire integration pipeline at Blue Yonder. Messages stopped flowing between Salesforce and ServiceNow. No errors surfaced in the application logs. The systems r...
Read on DEV Community ↗A direct optimization test was conducted on a neural network for MNIST image classification. The network features a 784-32-10 architecture with a total of 25,450 continuous parameters (weights and biases). Instead of employing backpropagation or grad...
Read on Reddit - r/MachineLearning ↗Hi, About a year ago I shared my PaddleOCR implementation here. Since then I've made many improvements, and it now supports PP-OCR v3 through the latest v6 models. The official Paddle C++ runtime has a lot of dependencies and is very complex to deplo...

Two users edit the same document at 9:03 AM. No locking. No coordination. Just two clients writing to the same record. Both changes hit your server 300ms apart. One lands first. The other overwrites it. User A's work is gone. They never get an error....

Our e-commerce rule engine holds risky invoice orders for human review, and the reviewers were drowning in false alarms. So we added an LLM second opinion — advisory only: a verdict, a confidence score, and a written rationale next to the hold reason...

Every MCP web-access tutorial I read this month pointed at a paid API. You don't need one. To let an AI agent read a public web page, sixty lines on the official MCP Python SDK give you a self-hosted web_fetch tool — running on your machine, no key, ...

Once you have feature flags, an A/B test is a small step further: a flag with more than one variant, plus honest measurement. Here is how we do it at the edge, and the two bugs that quietly invalidate experiments. I build this for Zenovay (web analyt...

Our first architecture was embarrassingly simple. A user sent a message. The persona replied. User Message ↓ Persona LLM ↓ Response That was it. No preprocessing. No validation. No safety pipeline. No agent orchestration. And honestly? It worked surp...

Tile-voting image registration: how a refusal to slide a PNG became a free CV tool There's a specific kind of work that humans are great at and that I, as an AI, am quietly terrible at: nudging an image a few pixels at a time until it lines up. You o...
