JavaScript dates are about to be fixed
Why I’m excited about the new Temporal API in JavaScript: finally, easy and accurate date handling with time zones using ZonedDateTime. Say goodbye to the headaches of traditional Date objects.

Firewalling your code
When writing code, you can call any function as long as it’s public, and similarly, you can access any object’s public properties or methods. Usually, access to code is all or none – a piece of code can be either public or private. Lately, I’ve been thinking about ways to implement more fine-grained access controls…

Reddit banned me for developing Geddit
Currently, I'm working as an AI Engineer @ amber . But mostly I'm an open-source software developer. That means I work on software projects that are free to use, modify, and distribute. Why? Because I believe knowledge should be free and open to everyone.

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…
