All trending →Recency-weighted, not all-time — what Reddit is talking about now.

#2 Structure and Interpretation of Computer Programs
Harold Abelson
MIT's 1985 Scheme textbook that 319 Reddit commenters have recommended and a noticeably smaller number have finished.

Martin Kleppmann
A backend engineer's field guide to the tradeoffs behind every database, queue, and distributed system you will ever touch.

A retired fund manager distills 40 years of index investing into one rule: buy VTSAX, ignore the noise, and wait.

Charles Petzold
A retired software engineer builds a computer from telegraph relays and flashlights, one chapter at a time, until you understand what a CPU actually does.

By year →

Frank Herbert
A duke's son survives his family's betrayal on a desert planet and becomes the prophet who leads its people to war.

Martha Wells

#4 Blindsight
Peter Watts
A crew of post-human specialists meets first contact and reports back that consciousness might be what's holding humanity back.

#6 The Way of Kings
Brandon Sanderson
A suicidal bridge slave assigned to the war camp's deadliest crew starts hearing storms answer when he gives orders.

Adrian Tchaikovsky
A terraforming experiment goes wrong, a nanovirus lands on spiders instead of monkeys, and evolution builds a civilization nobody planned for.
