Aerc: A well-crafted TUI for email
Aerc is a TUI email client. It had its first release ~4 years ago. This makes it a “baby” compared to most of its “competitors” (Pine was released in 1992, Mutt in 1995). I heard about this program shortly after its first release but ignored it at the time, because I was still reasonably happy with Thunderbird and it…

Async2 – The .NET Runtime Async experiment concludes
The .NET team has been working on a new experiment called async2, which is a new implementation of the async/await pattern that is designed to be more efficient and more flexible than the current implementation. It started with green threads and ended with an experiment that moves async and await to the runtime. This…

I sped up serde_json strings by 20%
I have recently done some performance work and realized that reading about my experience could be entertaining. Teaching to think is just as important as teaching to code, but this is seldom done; I think something I’ve done last month is a great opportunity to draw the curtain a bit. serde is the Rust framework for…

SIMD Matters: Graph Coloring
SIMD in game development Often in game development we talk about SIMD. It is the holy grail of CPU performance, often out of reach. The conventional wisdom is that it is difficult to achieve real gains from SIMD. It is tempting to build a math library around SIMD hoping to get some performance gains. However, it often…

Do low-level optimizations matter? Faster quicksort with cmov (2020)
Collectively, we have been thinking about sorting for longer than we have had computers. There is still an active literature 1 , 2 , 3 . We are taught that how the counts of comparisons and swaps vary with problem size is what matters: as problems get bigger, order dominates, and anything else is buried in the noise…

Async hazard: MMAP is blocking IO
Memory-mapping a file is convenient, but it's a hazard when used with async/await concurrent code: it means a "simple" memory index does blocking IO.

Code review antipatterns
Code review seems like a great idea, right? Two developers looking at the same code means two chances to spot problems; it spreads understanding of the way the project is evolving; the reviewer can learn useful tricks from reading the author’s code in detail, or spot opportunities to teach the author a useful trick…

Sourcegraph went dark
Towards the end of my mid-2019 job search, I was down to joining the Google Go team or Sourcegraph. Sourcegraph ultimately won due to cultural factors - the most important of which was the ability to build 100% in the open . All documents were public by default. Technical and product RFCs (and later PR/FAQs) were…

On the cruelty of really teaching computing science (1988)
The second part of this talk pursues some of the scientific and educational consequences of the assumption that computers represent a radical novelty. In order to give this assumption clear contents, we have to be much more precise as to what we mean in this context by the adjective "radical". We shall do so in the…

Bit-banging a BASIC Birthday
I spent this summer building a new app, for a machine that hasn’t been on the market since 1980 and wasn’t built to support graphics, sound, connectivity or even lowercase letters, sold by a company that went bankrupt a decade ago, tailor-made for an audience of one: my dad, who celebrated his 70th birthday this past…
