Hacker News Rabbit Hole

Hacker News /hn/ Show HN: I built a Jeopardy game maker with buzzer Writing a BIOS bootloader for 64-bit mode from scratch Building and scaling Notion's data lake Girl-P: SSH patch requests for 1337 GHS Firmware update hides a device's Bluetooth fingerprint Mazeppe: A modern supercompiler for call-by-value functional languages Nevada's public employee pension fund invests passively and beats peers (2016) PermitFlow (YC W22) Is Hiring Building the Bell System Show HN: Resurrecting a dead Dune RTS game Student uses black soldier flies to grow pea plants in Martian soil Giving Life to Ethelstan Compact Fenwick trees for dynamic ranking and selection (2019) It's pretty 4 years ago lol A Pretty pictures, bootable floppy disks, and the first Canon Cat demo? The Threads Creator Paradox A nonreasonable expectation of privacy in one's Google location data How an annual pre-pay creates an infinite marketing budget Disruptor-ts: better latency and throughput than crossbeam 19 The Peculiar Phenomenon of Hegamometers (2006) A Philosophy Professor's Final Class (2023) Writing a BIOS bootloader for 64-bit mode from scratch The 80286 has the Machine Status Word (MSW), a 16 bit register. The 80386 expands this to CR0, a 32 bits register. Then 64 bit long mode adds the EFER MSR and expands CR0 to 64 bits. Probably for more robust backwards compatibility with software that might assume a given value for or write to the reserved bits. note that you can switch to long mode directly, without going into protected mode first, with way less code How in the world do you fit all that in 512 bytes? yes, the kernel was in a known location on disk (directly after the bootsector)

The video browses a Hacker News-style /hn/ page filled with increasingly absurd and niche tech headlines, then zooms into a long discussion about writing a 64-bit BIOS bootloader from scratch. The joke is the contrast between the overwhelming hacker-news rabbit hole and the extremely deep, technical thread hidden inside it, presented like an endless internet time sink. The energetic background music makes the rapid browsing feel dramatic and comedic, as if discovering increasingly specialized nonsense is an adventure.
