Every number we watched said the run was working. Correct-per-sample probability tripled. The greedy accuracy curve was climbing. By the numbers on our dashboard, this was a textbook RLVR win.
Then we sampled the checkpoint 64 times per problem instead of once. pass@64 had collapsed from 0.83 to 0.
Who Saw the Connection? #04 — Railways × Human Factors × Software
If you spend enough time on a railway platform in Japan, you may notice something that looks oddly theatrical.
A conductor checks the platform, points down it, says something aloud, looks toward another reference point, and repeats
Commit counts measure activity. They do not measure whether any of it is still there.
I found this out while trying to describe my share of two private codebases in a way a stranger could check. Commits were the obvious number and the wrong one. On the frontend my share of surviving lines was highe
When an application is running, knowing that it is up does not necessarily mean knowing what it is doing.
For example, imagine an API request that takes several seconds to complete. We would want to answer questions such as:
Is the application receiving more requests than usual?

GPT-6 Astra at high reasoning effort produced the implementation I decided to keep. I still plan to use medium effort by default.
High handled the interactions between retries and persisted state more completely, but its implementation run took about 48 minutes against medium's 31. In a separate re
Hey everyone, As a side project, I wanted to build an alternative to legacy fragrance databases that are notoriously plagued by 10+ ad networks, sluggish client-side rendering, and bloated tracking scripts. The project is Olfactionary. The Engineering & Data Challenge: Relational Scale: Built a
Today I'm launching Docgrity — a tool for finding where your documentation disagrees with itself, before it confuses you or the next AI agent working on your codebase.
TL;DR
Docgrity is a documentation integrity tool for repos and Confluence. It finds duplicate or contradictory documentation, surf
Известный "кризис оснований математики", который произошел в начале XX века. Возник он из-за (или благодаря, тут трудно сказать) "Наивной теории множеств" Георга Кантора, которая на первый взгляд должна была стать точкой сбора всех математиков. Все мы, особенно разработчики, интуитивно понимаем теор
Chuks has two execution modes: a bytecode VM you develop against, and a native binary you ship. v0.1.1 is about making them agree everywhere, down to the last digit of an IEEE-754 float.
Chuks runs your code two ways.
A bytecode VM you develop against, it starts instantly, so the edit-run loop fee
Most sports games ask you to win a league. 38-0-0 asks you
to win every match of a Serie A season — 38 out of 38, where a single draw ends the run.
That constraint sounds like a difficulty slider set to maximum. It is not. It is a
different kind of game, and the reason is arithmetic that anyone can
An eight-frame animation does not have a fixed duration. At 8 fps it lasts one second; at 12 fps it lasts two-thirds of a second; at 16 fps it lasts half a second. Before drawing or generating more frames, check whether the problem is missing poses or the time each pose stays on screen.
We maintain
