Introduction The C string library is compact, fast and efficient. However, if not used correctly and carefully, it leads to buffer overrun errors which either cause programs to crash or worse allow…

Microsoft's Azure CTO Mark Russinovich explains why Windows still says a file is 'in use' after closing the app, and what to do about it.

macOS allows both the slash and colon as path separators, and this caused me no small amount of confusion.

The cost of thread context switch, including cache invalidation, can reach up to 3 million CPU cycles RTTI can be quite expensive, with dynamic_cast being up...

A few days ago Anthropic released a model that was initially too dangerous for the world. I tested it with my personal benchmark - can it create a game idea I've had for years in one shot?

How expert-parallel dispatch and combine kernels work, built up from scratch: the high-throughput shape and the low-latency one.

OpenCV 5 is here! A massive modernization brings a graph-based DNN engine, over 80% ONNX coverage, hardware acceleration, LLM/VLM support, and a faster Python-first core. Learn why this isn't just an incremental update.

Alexander Graham Bell is widely credited with inventing the telephone, in 1876. It’s not entirely undisputed: Elisha Gray, Antonio Meucci, and Johann Philipp Reis each also have a decent claim as w…

Have you ever looked at a USB connector or port and wondered why it was that color?

A warning about rising prices, vanishing consumer choice, and a future where owning a computer may matter more than ever as hardware, power, and control drift toward data centers and away from people.

Sometimes compilers can surprise and delight even a jaded old engineer like me

When programming, we chain functions together. Function A calls function B. And so forth. You do not have to program this way, you could write an entire program using a single function. It would be a fun exercise to write a non-trivial program using a single function... as long as you delegate the code writing … Continue reading The cost of a function call

The story goes like this. ComputerCraft is a mod that adds programming to Minecraft. You write Lua code that gets executed by a bespoke interpreter with access to world APIs, and now you’re writing code instead of having fun. Computers have limited disk space, and my /nix folder is growing out of control, so I need to compress code. The laziest option would be to use LibDeflate, but its decoder is larger than both the gains from compression and my personal boundary for copying code. So the question becomes: what’s the shortest, simplest, most ratio-efficient compression algorithm? I initially thought this was a complex question full of tradeoffs, but it turns out it’s very clear-cut. My answer is bzip, even though this algorithm has been critiqued multiple times and has fallen into obscurity since xz and zstd became popular.
