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…

Continuous reinvention: A brief history of block storage at AWS
Marc Olson, a long-time Amazonian, discusses the evolution of EBS, highlighting hard-won lessons in queueing theory, the importance of comprehensive instrumentation, and the value of incrementalism versus radical changes. It's an insightful look at how one of AWS’s foundational services has evolved to meet the needs…

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…

No "Hello", No "Quick Call", and No Meetings Without an Agenda
When working remotely, asking for help is often just a few keystrokes away. So it's tempting to "quickly" ask someone for support when you get stuck.

Ethernet History Deepdive – Why Do We Have Different Frame Types?
In my previous post Encapsulation of PDUs On Trunk Ports , I showed what happens to PDUs when you change the configuration of a trunk. You may have noticed that there are typically three different types of Ethernet encapsulations that we see:

Mourning and moving on: rituals for leaving a career (2014)
I decided to leave what had been a promising career in organic chemistry about a year ago. Deciding to leave my program, and then to leave the field entirely, was one of the hardest decisions I hav…

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…

“YOLO” is not a valid hash construction
Among the cryptographic missteps we see at Trail of Bits, “let’s build our own tool out of a hash function” is one of the most common. Clients have a problem along the lines of “we need to hash a bunch of different values together” or “we need a MAC” or “we need […]
