This is a fascinating project. I really want to build it myself, but your circuit in Fritzing is really confusing and has a lot of errors. That is why I would need days or weeks to build it, so can you please send me a circuit diagram or a working circuit in Fritzing. I want to add a net, a score counter and audio feedback. I have already made a visual net in Falstad (Note: It might look a little bit off, but it is mostly the fault of the t....

I recently built a little package to flash Emacs windows as you switch through them, so I might as well showcase it in a new Bending Emacs episode, so here it goes: Bending Emacs Episode 11: winpulse In addition to showcasing winpulse , we showed some of the built-in window-managing commands like: C-x 3 split-window-right C-x 2 split-window-below C-x 0 delete-window C-x ^ enlarge-window C-x } enlarge-window-horiz....

I Built Local Memory for Coding Agents Because They Keep Forgetting Everything

Here’s something that frustrates me about coding agents. They forget everything. Every single session starts from scratch. The agent that spent 45 minutes yesterday figuring out your authentication flow? Gone. The decision to use JWT over sessions? Gone. The bug it found in your ORM’s lazy loading? Gone. You start a new session and it re-discovers the same patterns. Repeats the same mistakes. Asks the same questions. It’s like working wit....

This is the story of how a RocksDB unit test I added four years ago, a mini-stress test you might call it, revealed a novel hardware bug in a newer CPU . It was scary enough to be assigned a “high severity” CVE. Background: Unique Identifiers About four years ago, we added unique identifiers to SST files to give them stable identifiers across different filesystems for caching purposes. Part of the motivation here was to eliminate our d....

This technology platform, called 'Just Walk Out', required over 1,000 workers in India manually reviewing video footage to verify transactions. By 2022, 700 out of every 1,000 sales needed human review. Amazon pulled the technology from their Fresh grocery stores in 2024. They paved the way. But it wasn't sustainable. The problem wasn't the concept. It was the complexity. Grocery stores carry thousands of SKUs, items without barcodes, an....

I started this blog as a fresh-faced, idealistic 22-year-old. I had just started my dream job at Google and was doing my truck thing, living life my way. The sky was the limit.

After six months of living this brave new life, precocious and optimistic at 23, I wrote a post titled Decimals And Dollars: Planning the Next Decade where I talked about financial i..

Until recently the LLM tools I’ve tried have been, to be frank, worthless. Copilot was best at writing extremely verbose comments. Gemini would turn a 200 line script into a 700 line collection of gibberish. It was easy for me to, more or less, ignore LLMs for being

New entry for the devlog: We now have a proper distinction between singleplayer/multiplayer-coop. The later one is now also fully functional. For coop I implemented player-specific colors, so it is possible to see who dropped which blocks (will be configurable in future). Without it looked a bit “chaotic”. Also I think it will be cool to see “who is faster”. I also thought about making the block drop round based… But I feel like this way it..

Another entry in the Toy Optimizer series . Last time, we did load-store forwarding in the context of our Toy Optimizer. We managed to cache the results of both reads from and writes to the heap—at compile-time! We were careful to mind object aliasing: we separated our heap information into alias classes based on what offset the reads/writes referenced. This way, if we didn’t know if object a and b aliased, we could at least know th....

What felt like yesterday but is actually closer to 4 years ago I released the first version of code spelunker (cs) and wrote about it here . I then promptly forgot about everything in it as I was focussed on everything else I had been working on, scc, searchcode, bonzamate, work, children. Since a few of those are now not something that need my constant focus I decided to revisit cs and improve it. I was also trialing claude code and i..

Iteration has long been one of the more fragmented areas of Go, with developers relying on ad hoc patterns to traverse custom data structures. This article explores the range-over-functions experiment, a proposed evolution of the language that introduces a standardized iterator model while preserving Go’s familiar for range syntax. Using the new iter package and sequence abstractions, it shows how iteration logic can be expressed more clear..

I’ve ended up with a bunch of these nice little ESP32-C3 modules . I’m a bit late to the party with them, so other people have done a lot of heavy lifting working out how to drive the display. I followed this blog . The only thing I didn’t quite like was the slight bodge in his drawing code where he used the U8G2_SSD1306_128X64_NONAME_F_HW_I2C class and then offset his code to work for 70x40 size display. There is now an appropriate....

Tools, thinking and people September 2007. I'm still a student but got my first job as junior software engineer working 30 hours a week after my classes. As a junior person I was assigned a mentor. His name is Vitalik. He is kind and extremely smart. He is well respected and works on important projects. I got lucky, he was a catch and other people got matched with way less brilliant engineers. I sit next to Vitalik. He is older, but....
