How I developed a Real-Time Micro Social App (Kcee Chatify)

Hey everyone! I just launched a new web project called Kcee Chatify, and I wanted to share it with the community. It is a real-time micro-social platform where anyone can drop a message to a public feed instantly. 🚀 Check out the live app here: https://kceechatify.netlify.app/ I wanted to focus on core web technologies and API routing, so I built it using: Frontend: HTML, CSS, and Vanilla JavaScript Backend: Node.js and Express Database: SQLite Hosting: Netlify (Frontend) and Render (

We paid real USDC 1,596 times to x402 endpoints. 653 settled.

x402 is the HTTP 402 payment protocol: a server answers 402 Payment Required with the price It does not prove that anything was delivered. We have been buying from that catalog with real money to find out what actually happens after $ curl -s https://vet402.com/api/v1/observatory/state l1.attempts 1596 l1.settled 653 l1.endpointsAttempted 1005 totalEndpoints 19023 activeEndpoints 15251 delistedEndpoints 3772 publishedPass 1246 publishedUnveri

Most Kubernetes clusters can't tell you what their GPUs cost

I built a small tool to answer one question: how many GPU-hours is a cluster paying for and not using? Then I pointed it at real production clusters. Not one of them could answer the question out of the box and the reasons are the same everywhere, because they're all defaults nobody changes. Here's what I found, in the order it bit me. Almost every GPU dashboard is built on DCGM_FI_DEV_GPU_UTIL. It's the obvious choice it's called utilization, it's a percentage, it goes up when things get busy

Tab is whitespace, so your TSV parser is not one

TSV is the format shell speaks. jq -r @tsv, git for-each-ref --format, ps --format, awk -F'\t' — when a shell script needs columns, it gets tabs. And the IFS=$'\t' read -r a b c That line does not read TSV. It reads something else that looks exactly like TSV until a column , and then it hands you the wrong value in a variable with the right name. Every listing below was re-run on the machine while writing this post. Nothing here is $ printf 'alpha\t\tgamma\n' | { IFS=$'\t' read -r a b c; printf

Introducing Crypts and Commits

The Audience I Didn't Know I Had — Part One There is a lot of conversation right now about one developer coordinating forty coding agents. I am not going to pretend I know whether that is good or bad. It is clearly a real model of working, and there are people doing remarkable things with it. But I keep coming back to a more ordinary question: what does agentic development look like for a team of ten developers, each working with one or two agents, while still staying in sync with one another?
