Last month I have been on a multi-day hike with my dad. Each of us took many pictures, and when we came back we put them all in a shared folder. We both have Android phones, and the naming scheme used for our pictures was the same: IMG_YYYYMMDD_HHmmss followed maybe by some other numbers and then a .jpg . Here YYYY…
GPT-5.2-Codex is OpenAI’s most advanced coding model, offering long-horizon reasoning, large-scale code transformations, and enhanced cybersecurity capabilities.
An overview of a class of data structures I didn't know about!

It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled…
Today, we're introducing Claude Code on the web, a new way to delegate coding tasks directly from your browser. Now in beta as a research preview, you can assign multiple coding tasks to Claude that run on Anthropic-managed cloud infrastructure, perfect for tackling bug backlogs, routine fixes, or...

I wrote about the new GLM-4.5 model family yesterday—new open weight (MIT licensed) models from Z.ai in China which their benchmarks claim score highly in coding even against models such …
From the Zed Blog: If you don’t want AI in your workflow, it won’t be there.
Blindspots in LLMs I’ve noticed while AI coding. Sonnet family emphasis. Maybe I will eventually suggest Cursor rules for these problems.
Why do compilers love xor-ing registers so much?
Thoughts, tools, and libraries I use to make games
Postgres 18 introduces Asynchronous I/O (AIO) that can dramatically improve read performance, especially in the cloud. Learn how these changes and the new io_method setting work and see why our benchmark results show that io_uring is the recommended setting for maximizing I/O performance in Postgres 18 over the…
Atuin Desktop looks like a doc, but runs like your terminal. Script blocks, embedded terminals, database clients and prometheus charts - all in one place.
What `git config` settings should be defaults by now? Here are some settings that even the core developers change.
One of life's greatest simple pleasures is creating something just for yourself.
Backlog getting you down? Drowning in technical debt? Delegate issues to Copilot so you can focus on the creative, complex, and high-impact work that matters most. Copilot coding agent makes…
I wrote a (list of) regular expressions that will play a (not very good) chess game by running a 2-ply minimax search.
🖍️ Explaining multiple techniques for rendering outlines and highlights for real-time applications. This includes vertex object-space as well as screen-space methods. This can be used to render outlines in Unity or Unreal. Outlines can be used for gameplay reasons or aesthetics.
Made in Notion, the connected workspace where AI agents and teams organize docs, projects and knowledge together.
This started as an internal Sanity workshop where I demoed how I actually use AI. Spoiler: it's running multiple agents like a small team with daily amnesia.
From the Zed Blog: Zed for Windows is finally here. Download it today.
i have gone a little above and beyond trying to get all the features of VSCode
A step-by-step guide to building a key-value database from scratch.
Practical guidance from Anthropic on building reliable AI agents, from simple composable patterns to fully autonomous systems.
In early 1982, the Lisa software team was trying to buckle down for the big push to ship the software within the next six months. Some of the managers decided that it would be a good idea to track the progress of each individual engineer in terms of the amount of code that they wrote from week to week. They devised a…
Google is releasing updated Gemini 2.5 Flash and Flash-Lite preview models with improved quality, speed, and efficiency.
