How fractal-layer attacks the compilation bottleneck and initialization chaos of the monolithic App datatype by treating startup as a composable graph of resource-managed layers.

Waarom de vermogensaanwasbelasting slecht uitpakt — voor de belastingplichtige, de schatkist en de economie. · Why the accrual tax is bad for the taxpayer, the Treasury, and the economy.

Knuth's full quote on premature optimization and how the slogan gets misused

Brooks's distinction between essential and accidental complexity in software systems

A beginner-friendly tour of parameters, quantization, MoE, context windows, and other LLM jargon.

How to eliminate the three performance taxes that make database queries slow: encoding overhead, round-trip latency, and N+1 query patterns.

Archived from Informatikr (originally published January 18, 2012). Describes how the Haskell Redis client Hedis achieves automatic and optimal pipelining by combining lazy I/O with a synchronous-looking API, getting the best of both synchronous and asynchronous approaches.

Type systems verify properties of programs. Production correctness is a property of systems. The gap between these is where the interesting failures live.

The control plane pattern (a coordinator that tells workers what to do) shows up everywhere good infrastructure exists. The concept is simple. Naming it is useful.

Some engineering decisions punish you for being wrong. Most don't. Learning to tell the difference and calibrate your deliberation accordingly might be the most valuable skill your team never explicitly develops.

Local benchmarks revealed HTTP/3 can be 50-100x slower than HTTP/2. QUIC's userspace implementation loses to decades of kernel TCP optimizations on high-bandwidth, low-latency networks.

The trick that makes GHC’s ApplicativeDo optimization faster is structurally identical to how biologists predict RNA folding.
