execution

RustConf 2020 closing keynote by Sian Griffin that dives into Pokemon Blue glitches, notably Missingno and arbitrary-code-execution tricks. It uses them to explain how memory unsafety works and how memory-safe languages like Rust prevent such bugs.

The fail0verflow team (bushing, marcan, sven) present console hacking at 27C3, covering Wii, Xbox 360 and PS3 exploits. They explain how the PS3 was cracked after Sony removed Other OS.

The fail0verflow 27C3 talk on breaking PS3 security, covering how Sony's implementation failed, including its ECDSA mistakes.

A short demo of a playable Space Invaders game built inside Dwarf Fortress, with a downloadable map. It shows the game's mechanics used as a computing substrate.

The BotHack NetHack bot wins the game for the first time with no cheats or human intervention, in a run lasting about 3.5 hours. The description links the source code and the dumplog.

Cliff Click walks through a small performance example on a modern out-of-order CPU. He covers pipelining, ILP, CISC vs RISC, multicore, and why cache misses and the memory subsystem dominate performance.

Michael Hendricks of PriceCharting shares tricks and pain points from running Prolog in production for 18 months at Strange Loop. It argues Prolog is a productive modern language beyond logic puzzles, and includes a demo of changing code mid-execution.

Netanel Rubin's 31C3 talk chains Perl's syntax quirks into a powerful remote code execution attack, taking down popular Perl-based projects.

A 1990 lecture by James Gosling on NeWS, Sun's networked window system in which clients send PostScript programs to the server for execution. It covers the high-level imaging model and compares NeWS with similar systems.

A five-minute demo of the Common Lisp debugger fixing a bug, recompiling a single function, and resuming execution from the failed stack frame. It shows how to avoid re-running long computations.
