Programming Digest
Transistors power everything in GPUs. Jason built a game where you construct one from scratch. Also, five git commands that reveal codebase health before reading a single line — spotting risky files in minutes.
Too many approval layers slow teams down through waiting, not effort. AI speeds up coding but won't fix slow review pipelines. Also: shell shortcuts like CTRL+R and brace expansion that save real time, one trick at a time.
How JPEG compression exploits human vision to shrink images. Why queues don't fix traffic spikes—they just delay the pain. And how RollerCoaster Tycoon ran smoothly on 1999 hardware by turning technical limits into design features.
CPU branch prediction limits vary wildly by chip—AMD handles 30,000 learned branches, Apple 10,000, Intel just 5,000. Meanwhile, the IBM 9020 from the 1960s tracked flights across the US with sub-30-second failover, and its software outlasted the hardware by decades.
Docker turns 10 — it solved "works on my machine" by bundling apps with their dependencies using Linux process isolation. Containers aren't magic though: they share the host kernel, so skipping basics like non-root users and dropped capabilities leaves everything exposed.
Errors in software are either expected (bad input, network issues) or unexpected (bugs). Treat more as expected to build reliable software. Also: how Notion tracks offline pages using a two-table system that prevents accidental removal when one reason disappears.
