Je m’appelle Firmin Firmin, développeur et créateur originaire de la République Démocratique du Congo (RDC). Je construis des projets autour de : l’intelligence artificielle les applications web modernes (PWA) les terminaux de développement en ligne les applications Android générées depuis le Web Mo
I've been building small web tools with AI coding for the past few months. Here's one that people actually use: LivePhotoKit — a free, browser-based converter for iPhone Live Photos, HEIC images, and more. iPhone users shoot millions of Live Photos and HEIC images every day. But when they try to: Se
I've been on both sides of the GitHub issue wall. As a contributor, I've spent time writing what I thought was a decent bug report, only to get a one-liner back: "Can you share a repro?" Three days later I reply. No response. Issue goes stale. As someone who's poked around in open source repos, I've
Most file-sharing platforms are designed around permanence. Upload a file today, and chances are it will still be sitting on a server months later unless someone manually removes it. While that makes sense for cloud storage products, it is often unnecessary for temporary file transfers. Many users s
Your contrast checker probably lies about rgba() text. Most checkers — and most hand-rolled WCAG snippets — assume both colours are fully opaque. The moment your text or its background uses rgba() or opacity, the numbers can be off by a full pass/fail. Here's why, and the one extra step that fixes i
Agent handoffs are where multi-agent systems stop being routing diagrams and start becoming production software. Handoffs between agents in a multi-agent system, i.e., how a customer is being transferred from one agent to another, typically a specialist to another specialist for another question, in
AI agent governance after the tool call is audit paperwork, not control. Even small actions have side effects: sending an email, updating a customer's details, approving a refund, updating a Salesforce opportunity, or even simply spending money from a wallet. Each of these actions has a useful side
Approving an MCP server once for production is the first step in securing MCP. The real danger comes after that when the surface that the model is interacting with changes slowly but fundamentally. A read-only customer lookup tool becomes an export tool. A database helper adds a required raw-SQL par
Every developer eventually faces a difficult choice: Build another to-do app. Or create an absurdly over-engineered game with eight interconnected worlds, giant numbers, prestige systems, and enough gears to make a Victorian engineer cry tears of joy. Naturally, I chose chaos. Cog & Cosmos: The Fort
You built a solid internal tool. It manages customers, tracks orders, handles operations. Your team lives in it every day. Then someone in leadership asks: "Can we get a report showing monthly revenue by plan type, broken down by region?" And you realize — your tool has no reporting layer. No charts
Hi everyone! I’m currently building a custom programming language called Swiq using C++. Most modern languages rely entirely on standard garbage collection or strict block scoping. When I designed Swiq, I wanted to give developers first-class semantic keywords to handle state management natively at
Claude Code and similar coding agents are strongest when the task requires judgment: architecture, unclear requirements, production incidents, security-sensitive logic, and hard debugging. The problem is that many teams also use the same strongest model for routine work: small tests, README edits, t
The Google Home Speaker is set to start shipping very soon but, ahead of that, one user was able to buy one from a retail store early. They’ve since shared their first impressions, which unfortunately confirm that the speaker has a fixed power cable that’s also pretty short.
Effective next week, Google’s parent company, Alphabet, is being added to the Dow Jones stock index.
Testing webhooks locally is one of those problems that sounds simple until you actually try it. Your GitHub webhook needs a publicly routable URL, but your development machine is behind a NAT or firewall. You can't just point GitHub at http://localhost:3000/webhook—GitHub's servers can't reach it. T
I spent years working on data infra. I got tired of the manual grunt work, so I built CreatiVault to automate my benchmarking and influencer tracking. It does the job perfectly for me, but I’m struggling to get anyone else to try it.I’m a dev, not a marketer. So I have to ask: Is my product actually
Retrieval-augmented generation looks trivial in a tutorial: embed some documents, drop them in a vector database, stuff the top matches into a prompt, done. Then you point it at real company data and real users, and you discover that the demo was the easy 10%. We build RAG systems over private knowl
The 2026 FIFA World Cup in North America is reshaping one of sports' most fundamental probabilities: the likelihood of a "Cinderella story" advancing from the group stage. For the first time in the tournament's history, we have a 48-team format split into 16 groups of 3, where the top 2 teams advanc
The "Forgotten Server" Problem Every developer has been there. You spin up a temporary staging instance to test a deployment script, or you launch a quick Redis container to debug a caching issue. You intend to tear it down in an hour, but then a Slack notification hits, a meeting starts, and that i
Check this out: how I Stopped Overpaying For AI Models (And You Can Too) honestly, I gotta say... I'm pretty bad at math when it comes to my own money. I was burning through cash on AI infrastructure like it was going out of style before I finally sat down and did the math. And what I found kinda pi
