How to make Firefox builds 17% faster
In the previous post, I mentioned that buildcache has some unique properties compared to ccache and sccache. One of them is its Lua plugin system, which lets you write custom wrappers for programs that aren’t compilers in the traditional sense.

Allow babywearing carriers on planes
The FAA has one of my favorite examples of thoughtful rulemaking. They haven't banned flying with a baby on your lap, because the extra cost would mean many parents would drive instead. Since driving is far less safe than flying, a ban would lead to more deaths. I'd love to see more of this "all things considered"…

The unbearable cheapness of open weight models
Today I was setting up Hermes to see how it does with web research. I chose DeepSeek V4 because I know it is cheap, but seeing it’s pricing next to Anthropic and OpenAI ‘frontier’ models is crazy. Nearly a 50x price increase based on tokens alone, let alone how much pondering any of their models might fall into (using…

LibreOffice – Let's put an end to the speculation
Ideally, we would have preferred to avoid this post. However, the articles and comments published in response to Collabora’s and Michael Meeks’ biased posts compel us to provide this background information on the events that led to the current situation. Unfortunately, we have to start from the very beginning, but…

Girls just wanna have fast MPMC queues with bounded waiting
Disclaimer: An earlier version of this post claimed the structure is wait-free, this is incorrect. Being wait-free requires that failure or suspension of any thread can’t cause failure or suspension of another thread. This queue in fact does not fulfill that requirement. The main section which discusses the wait…
