Big O is terrible for reasoning about perf on modern CPUs when caching comes into play Arrays are more cache friendly. CPU caches make memory accesses very very cheap (3-4 cycles for L1 cache) Hashset lookups are more costly Big O ignores constants and completely ignores this

Your SSD runs a (light) operating system. It’s often more powerful than your home router. Peek at any NVMe drive; chances are, it has 2-4 ARM Cortex Cores at ~1GHz. Real-Time Operating Systems like ThreadX dominate the space, but some specialist drives boot Linux!

PC apps moving from direct downloads to app stores is a regression, cursed, tragic. One of the greatest advantages of PCs is their openness and the door is closing. The web browser + the open OS remain the pillars of the free web.
