C++26: Trivial infinite loops are no longer undefined behaviour
Let’s start with a question! Is this program well-defined? 1 2 3 4 int main() { while (true) ; } If you said yes, you’d be wrong — at least before C++26. A while (true); loop with no side effects used to be undefined behaviour. Compilers were free to assume it terminates, and some — Clang in particular — would…

Protobuf has LSP support
Buf is proud to announce the first fully-featured, spec-compliant LSP server for Protobuf. The Language Server Protocol is the standard API for integrating language support into your favorite IDE or text editor, such as VSCode, IntelliJ, or Neovim. An LSP server provides the smarts that power go to definition, code…

I made a build visualizer to understand Bun's compile times
I built buildprof (Github), an open-source tracing tool that shows where the time goes when you compile software on Linux. Here’s a realtime video of it profiling a clean build of ripgrep: Watch the …

Fixing Tool-Call Accuracy in vLLM
Tool call accuracy is an important part of serving open-weight AI models. When your tool calls aren’t accurate, the model builds up on nonsensical context. We’ve been carrying our own fork of vLLM to hit 100% in tool call schema accuracy with Kimi and DeepSeek. Fortunately, vLLM 0.31 added support for constrained…

Understanding the Go Compiler: The Linker
In the previous post , we watched the compiler transform optimized SSA into machine code bytes and package them into object files. Each .o file contains the compiled code for one package—complete with machine instructions, symbol definitions, and relocations marking addresses that need fixing. But your program isn’t…

An ode to bzip
The story goes like this. ComputerCraft is a mod that adds programming to Minecraft. You write Lua code that gets executed by a bespoke interpreter with access to world APIs, and now you’re writing code instead of having fun. Computers have limited disk space, and my /nix folder is growing out of control, so I need to…

A shell exclamation mark is not for yelling. Be lazy
Event designators have been hiding in not-so-plain-sight since the late 1970s — so powerful that forgetting might be part of a massive conspiracy to wear out developer keyboards faster than otherwise.

Signals, the push-pull based algorithm
We have been using Signals in production for years via several modern front-end frameworks like Solid, Vue, and others, but few of us are able to explain how they work internally. I wanted to dig into it, especially diving deep into the push-pull based algorithm, the core mechanism behind their reactivity.

Footguns with Postgres “at time zone 'UTC'”
And why you may need to repeat AT TIME ZONE 'UTC' twice. SUMMARY * AT TIME ZONE 'UTC' converts the data type from timestamptz to timestamp (example). * Now you are inadvertently using the timestamp without time zone (aka timestamp) data type, which is markedly discouraged. * There are tons of footguns with timestamp…

Provide agents with automated feedback
Back pressure for agents You might notice a pattern in the most successful applications of agents over the last year. Projects that are able to setup structure around the agent itself, to provide it with automated feedback on quality and correctness, have been able to push them to work on longer horizon tasks. This…
