Twice the bits, twice the trouble: vulnerabilities induced by migrating to 64-bit platforms | the morning paper edit / delete

"In this study, Wressnegger et al. reveal how a codebase originally written for 32-bit, and which is perfectly secure on 32-bit platforms, can have new vulnerabilities simply by compiling it for 64-bit systems." No surprises for anyone who follows oss-security etc., but the paper's a good overview.

Proposed Electronic Calculator, by Alan Turing (48 pp.) undated edit / delete

Proposal for what became the ACE, circa 1945. Among many other things, this introduces the BURY and UNBURY opcodes (which these days we'd call PUSH and POP) and their application in function linkage.

Friends of Williamson's Tunnels | est. 1996 edit / delete

"The Williamson Tunnels are a labyrinth of tunnels and underground caverns under the Edge Hill district of Liverpool in north-west England. They were built in the first few decades of the 1800s under the control of a retired tobacco merchant called Joseph Williamson."

RETRO DUNDEE edit / delete

An impressive collection of photos of Dundee from the 60s-80s. It's amazing how much the city centre has changed (in many cases, twice, after the council has realised that the concrete eyesore that replaced a bit of classic Scottish architecture was not as good an idea as it originally seemed).

How to get away with disabling DRAM refresh « Reenigne blog edit / delete

Speeding up a demo for the IBM PC by disabling DRAM refresh, since the program accesses all the memory that needs refreshing regularly anyway. Neat.
