Control, escape, and meta tricks
Open a Unix or Linux terminal emulator. If you have Terminal.app on macOS, ensure that the "Use Option as Meta Key" option is enabled in its "Preferences" section. Now type foo bar baz followed by meta + b (i.e. alt + b or option + b on modern keyboards). In a typical desktop environment with a typical and modern…

Transcoding Latin 1 strings to UTF-8 strings at 12 GB/s using AVX-512
Though most strings online today follow the Unicode standard (e.g., using UTF-8), the Latin 1 standard is still in widespread inside some systems (such as browsers) as JavaScript strings are often stored as either Latin 1, UTF-8 or UTF-16 internally. Latin 1 captures the first 256 characters from the Unicode standard…

Adding design-by-contract conditions to C++ via a GCC plugin
Design-by-Contract's invariant attribute allows you to enforce important properties of systems and data structures, making it an incredibly useful tool for developers. In this blog post, we'll be exploring the development of a GCC plugin that adds support for [[invariant]] conditions in C++ classes and structs. We'll…

Transactions Are Not Locks (2022)
One thing I wish I had understood better earlier on in my experience with PostgreSQL is how transactions and locks can be used together to provide serializable logic.

Go 1.21 will (probably) download newer toolchains on demand by default
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of.

The Case for Bash (2021)
Bash is oft-maligned: you hear it sneered at in sentences like “our continuous integration pipeline is just a pile of bash scripts .” It is commonly regarded as unintelligible and thus unmaintainable. The pile of bash scripts are the toxic byproduct of an infrastructure team understaffed, pressed for time, unwilling…

Practical Libc-free threading on Linux
Suppose you’re not using a C runtime on Linux, and instead you’re programming against its system call API. It’s long-term and stable after all. Memory management and buffered I/O are easily solved, but a lot of software benefits from concurrency. It would be nice to also have thread spawning capability. This article…

Who invented vector clocks?
Back in spring 2020, I was wrapping up the distributed systems course I was teaching, and for the last lecture, decided to spend a little time poking at the question of who actually invented vector clocks. Most people who need something to cite for vector clocks cite Friedemann Mattern’s “Virtual Time and Global…

Iterating on Testing in Rust
With the release of rust 1.70, there was some surprise and frustration that unstable test features now require nightly , like all other unstable features in Rust. One of the features most affected is --format json which has been in limbo for 5 years . This drew attention to a feeling I've had: the testing story in…
