First Contact with SQLite
I've been playing around with SQLite the last couple of days. I thought I knew a little about SQLite, but I didn't, and am getting my remedial education through an accelerated gauntlet. Some of what …

On the Costs of Syscalls (2021)
It's well known that syscalls are expensive. And that software mitigations against CPU bugs (such as Meltdown) even have made them more expensive. But how expensive are they really? To begin to answer this question I wrote a small micro-benchmark in order to measure the minimal costs of a syscall …

C++11 FQA anyone?
isocpp.org announced "the C++ FAQ" to which reportedly Bjarne Stroustrup and Marshall Cline will link to help boost its search rank. Good stuff; also, given that the language is >30 years old – it's about time.

Does Go Have Subtyping?
I’ve been noodling on a static type system for my current hobby language. To try to keep the language as simple as possible, I’m trying to see if I can live without subtyping. Since most of my programming experience is in object-oriented languages, I’ve been learning more about languages that lack—or at least claim to…

Compile-Time Evaluation in the Zig System Programming Language
Zig places importance on the concept of whether an expression is known at compile-time. There are a few different places this concept is used, and these building blocks are used to keep the language small, readable, and powerful.

Randomness extractors: making fair coins out of biased coins
I discuss various models of biased bit sequences, and how to extract uniform random (or close to it) output bit sequences from them, illustrated with Python code.

Use `nproc` and not grep /proc/cpuinfo
There’s something really quite subtle about how the nproc utility from GNU coreutils works. If you look at the man page, it’s even the very first sentence: Print the number of processin…

The Hardest Program I've Ever Written (2015)
The hardest program I’ve ever written, once you strip out the whitespace, is 3,835 lines long. That handful of code took me almost a year to write. Granted, that doesn’t take into account the code that didn’t make it. The commit history shows that I deleted 20,704 lines of code over that time. Every surviving line has…

Frameworks are for hacks, libraries for seeds
I find that I operate in one of two modes when I’m writing software. I’m either approaching a project as a quick hack or as developing software . As much as anything else, this affects how I approach the project and what kinds of results that I get.

Church vs. Curry Types
Static vs dynamic typing debates often flounder because the debators see from two different perspectives without knowing it. Learning to identify the two perspectives can calm the discussion. The tension between the two perspectives has led to Gradual Typing and other technologies.

The Simulated Annealing Algorithm
Simulated annealing is a method for finding a good (not necessarily perfect) solution to an optimization problem. If you're in a situation where you want to maximize or minimize something, your problem can likely be tackled with simulated annealing.

Self hosted C – breakdown
