AI Agents, Tools And How To Make Sense Of It All

A lot of the self hosting questions on here turn out to be hardware questions rather than software questions, and the answers usually skip the boring part. This is the version I wish someone had handed me before I rented the first box for an always o...
Most of us have had a test suite that passed locally, failed once in CI, then passed on the rerun until nobody trusted it as evidence of anything. This is about why that happens, and why one framework's default behavior removes most of it.
Flake Is ...
Most of us here have written a scraper or a browser test suite that worked beautifully until someone shipped a redesign and every selector went stale overnight. This is a look at what actually changes when an agent reads the page instead of replaying...
Most of us reach for a vector database the first time an app needs memory, and it holds up right until it does not. This is the piece that changed how I score retrieval, so I am putting it here in case anyone else is hitting the same wall.
A retriev...
Most of us here have written or inherited the glue that moves an order from a storefront to a fulfillment provider to an accounting ledger. This is a look at where that glue breaks in production, and what a sane order of operations looks like when yo...
Most of the PWA writing out there is aimed at content sites, and games break those assumptions immediately because the asset budget is an order of magnitude larger. This is the split that has worked for us, written for people who ship builds rather t...
Most of us here have shipped something with an LLM behind it and then watched a user hit the same wall: the thing has no idea what happened yesterday. This is a walk through what a memory layer actually does, in the order the code runs, because the f...
Most of us here have been handed a no-code prototype and asked to make it production ready. This is a look at where that handoff usually breaks, and what changes when the platform emits real server side code instead of a configuration blob.
The Ceil...
Most of the agent cost threads here end up arguing about frameworks, but in practice the bill is set by two decisions that get made in the first hour and never looked at again. Sharing the numbers because they are easy to check against your own setup...
Most of us here build the store rather than run the marketing for it, so SEO tends to arrive as a ticket with no acceptance criteria attached. This is the measurement half of that problem, written for whoever has to prove the work did something.
Ran...
Most of us learned to code by watching somebody else do it, and then discovered that watching and doing are two different skills. The tools that moved the needle were never the ones that explained better, they were the ones that made me produce the a...
Most of us here already reach for Compose the moment a project grows past a single process, and agent work hits that point faster than almost anything else. What follows is the shape that keeps showing up once an agent stops being a script and starts...
Most of us here ship code that has to behave the same on someone else's machine, and we lean on containers and lockfiles to get there. Scientific code has the same problem with a nastier failure mode, because when it breaks nothing crashes, the progr...
A lot of the browser game questions that land on here come down to physics behaving one way on the dev machine and another way on someone else's, and the engine is almost never the reason. This is the version of the explanation I wish someone had giv...
Most of us have written the same glue between an LLM call, a vector store and half a dozen APIs more than once, and the pitch for any visual layer is that you stop rewriting it. If you are weighing that against another bespoke script, the first thing...
Most of us here write code that runs on transistors, and almost none of us ever had a reason to ask why a transistor works at all. This is a short tour of the physics that answers that question, written for developers rather than for physicists.
Qua...
Most of us here have shipped an MCP server by now, and the debugging stories are all suspiciously similar. These are the three failure patterns behind almost every "my server is broken" thread, and none of them are actually bugs in the server.
Trans...
Most of us here have watched an agent confidently rewrite a function nobody asked it to touch, then spent the next twenty minutes rewording the prompt to make it stop. This is the writeup I wish I had read before doing that for the tenth time.

A lot of the WebGL questions that land here turn out to be performance questions wearing a syntax costume, so this is the profiling angle rather than the GLSL tutorial angle. If you have ever stripped a scene down to fewer triangles and watched the f...
