How Linux Took Over the World of Finance
summary
Chronicles the concrete path Linux takes from trader desktops to exchange matching engines, claiming industrywide dominance by ~2009 as traders adopt kernel hacks, multicast improvements and DPDK and SPDK bypasses to shave microseconds. Describes C++ as the de facto language, submillisecond matching engines and edge colocations, exchanges migrating ~5 years after quant shops, and the practical hit of the speed of light limit driving fiber straightening and microwave links. Notes Red Hat/Ubuntu/Debian prevalence and Solaris collapse after Oracle, and shows Linux actually enables the extreme low-latency stacks used today.
