In 2017, we looked at how web bloat affects users with slow connections . Even in the U.S., many users didn't have broadband speeds , making much of the web difficult to use. It's still the case that many users don't have broadband speeds, both inside and outside of the U.S. and that much of the modern web isn't…
One of the key gaps in Rust’s ecosystem has been a strong story for fast and productive asynchronous I/O . We have solid foundations, like the mio library, but they’re very low level: you have to wire up state machines and juggle callbacks directly.

Five Rust-level memory optimizations to the DNS cache layout of Big Pineapple cut per-entry memory by 56%, freeing approximately 100 TB of memory across Cloudflare's fleet.
For the first time, a large high-temperature superconducting electromagnet was ramped to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created. The demonstration helps resolve the greatest uncertainty in the quest to build the first fusion power plant that can produce more energy than…
People call WebAssembly a game changer because it makes it possible to run code on the web faster. Some speedups are already present, and some are yet to come. With ...

We're open sourcing postgres-wasm, a PostgresQL server that runs inside a browser, with our friends at Snaplet.
The first thing I check when debugging latency issues in distributed systems is whether TCP_NODELAY is enabled. And it’s not just me. Every distributed system builder I know has lost hours to latency issues quickly fixed by enabling this simple socket option, suggesting that the default behavior is wrong, and perhaps…
A new generation of collaborative software that allows users to retain ownership of their data.
With the R515 driver, NVIDIA released a set of Linux GPU kernel modules in May 2022 as open source with dual GPL and MIT licensing. The initial release targeted datacenter compute GPUs…
Explore Plan 9, Bell Labs' innovative operating system. Discover its impact on distributed computing, network-centric design, and modern OS development.
A look at modern news websites. How programmatic ad-tech, huge payloads and hostile architecture destroyed the reading experience.
The Firefox Quantum release is getting close. It brings many performance improvements, including the super fast CSS engine that we brought over from Servo. But there’s another big piece of ...
This week I was in Rotterdam for a RIPE meeting . On Friday morning I gave a lightning talk called where does my computer get the time from? The RIPE meeting website has a copy of my slides and a video of the talk; this is a blogified low-res version of the slides with a rough and inexact transcript.
In 2020, Apple released the M1 with a custom GPU. We got to work reverse-engineering the hardware and porting Linux. Today, you can run Linux on a range of M1 and M2 Macs, with almost all hardware working: wireless, audio, and full graphics acceleration.
And what that means for the rest of us.
macOS comes with a lot of built-in utilities. Here's a list of some that I find interesting.
A big percentage of so-called experts today only know how to configure tools, but they understand nothing about how things work at the deeper level. This is a real challenge and a big problem for the future.
