Needed 1+1, Built a Functional Programming LanguageFrom a data-structures homework tree to closures, a chunk allocator, and a mark-and-sweep GC in C
A playful systems write-up: starting from evaluating 1+1 as a binary tree, the author builds a graph-reduction language in C with closures, a chunk allocator, and a garbage collector that cuts fib(40) from 12GB to 1.7MB.

English: a vs anWhy vowel letters are the wrong rule for indefinite articles in generated text
Amit Patel (Red Blob Games) digs into when English wants “a” versus “an”: the rule tracks spoken vowel sounds, not written vowel letters, and only a small set of common words need exceptions for procedural text generation.

llmman launch dsh: Run DeepSeek Harness on any local or hosted model
DeepSeek Harness treats the model as a plugin. llmman runs any model on your own hardware, in one command. An agent harness is a loop around your model that takes your task, calls a model, runs tools (such as shell commands and file edits), provides results, and repeats.

When the fractional part of a float fixes your shader
Bruno Croci debugs a Voronoi Shadertoy stutter that only appeared on a Windows RTX 4070: ANGLE/FXC optimizations dropped `fract` for integer-looking inputs, and swapping a literal to `398.1` or using `x-floor(x)` restored smooth motion.

How I Test MCP Tools and MCP Apps
An MCP tool can pass normal tests and still fail when an agent tries to use it. The implementation may be correct, but the model may choose the wrong tool. It may send the wrong arguments. The tool description may be too vague.
