Brings back a lot of memories of assembly programming on the Acorn Archimedes[1] (ARM2 core) back in the early 90s. It certainly was a revelation (all those registers!) after years of messing around with Z80/6502/80[123]?86. 1. h

For my Comp Sci degree I wrote a regexp/automata library. It allowed you to create/modify/load/save/execute NFAs, and the same kinds of functions for a basic regexp language (character classes, ., Kleene star *, ?,

Don't forget that most symmetric encryption algorithms can be used as a hash. Just encrypt a known plaintext (usually all NUL bytes) using the password as the key.

Hmm, if that was me (as the server programmer) I'd return a purposely different checksum[1] in the error message and then (internally) flag anything that was then submitted with that 'incorrect' checksum. What you do with the

I'm guessing the GP was referring to the fact that Levison didn't update Lavabit to prefer ciphers that provide perfect forward security. Here is his own admission on the subject:- " When I was designing the Lavabit encrypted

That's the major difference between hubs and switches. As a generalisation: hubs just push everything received from one port out to all ports. Switches are cleverer in that they only direct the right traffic (that may include broadcast

Probably because the memory allocated just happened to contain only NUL bytes where that specific cleanup function pointer is stored whenever it was run in testing. The point is that a targeted malicious attack would try and ensure that tho

ACID doesn't apply since you can't copy a large file in an instant. The copy takes time, in which time the files on disk can change. This isn't the same thing as the server losing power. VM snapshots, zfs snapshots, etc are t

Depending on what you use the IP for, asking a third party for your IP address could be an interesting attack vector for a MitM attack. e.g. you need your IP to tell a remote server to send you something. You connect to the IP address servi
