For months, the recording engine was the hardest part of the product to make reliable. We'd fix one class of edge case, ship it, and a new one would surface the next week. Different root causes, same pattern. The engine ran in the render process of our Electron app. We tried the obvious fixes: tighter lifecycle management, moving work off the main thread, isolating it from React's render cycle. Each…

We went into a lot of detail on how the kernel was launched, but we also left a lot out. This time, we’re going to address our omissions, and follow the path the critical SASS instruction (a global load) takes through the hardware — in this case, since it’s under my desk, an RTX 4090We do this kind of reverse engineering…

Searle Web Master, TRON Web The BTRON Computing Model Although it may not seem like it, what can broadly be termed "personal computing devices" are based on only three conceptual models. In order of their historical appearance, they are: the "stand alone computer model," which first came into being as the batch processing mainframe with a command line interpreter; the "networked stand alone computer model," which saw its first incarnation as the object-oriented workstation with a graphical user interface…

Anyone who's pasted a specific error message into a search box recently knows the experience. The first several results are usually SEO content, the same underlying answer reworded…

Police in Union Township, a Cincinnati suburb, accused Cody Morelock of disassembling the camera, its support pole and solar panel on June 13.

💥 Check out this trending post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Introduction When evaluating high-performance database architectures, the conversation often centers on horizontal scaling, distributed partitioning, and query optimization. However, for mission-critical transactional systems like financial ledgers, the real bottleneck is rarely the network or the query planner; it is the operating system kernel, memory fragmentation, and unpredictable tail latency. TigerBeetle, a specialized financial ledger database written in Zig, challenges conventional database design by prioritizing extreme mechanical sympathy, static resource allocation, and custom zero-copy interfaces. I have spent years analyzing distributed storage engines, and TigerBeetle’s…

Not because the alternative was Unix-based or because Apple pulled off something different, but because an operating system designed at the University of Tokyo in 1984 was ambitious enough to try to replace the file system with a hypermedia document model, run on a custom Japanese CPU architecture, and encode 1.5 million characters, only to have a US trade report single it out as an unfair trade barrier in 1989. That…

Firecracker strips the emulated hardware down to what a Linux kernel needs, giving each build the isolation of a virtual machine with startup close to the cost of a container. Firecracker drives KVM, so it needs a Linux host with /dev/kvm, which no Mac has, and most engineers at Encore develop on a Mac. The maintainers have no plans to close that, given they…

It's hard to pin it down to a genre even today, but it certainly wasn't like previous Meier titles—even though it's the first game to be called Sid Meier's Something or Other. At the time the game came out in 1987, it was generally…
