The antenna is very similar to antirez's. The distance between dipole wire ends is 130 mm (not 137 mm in order to compensate for wire thickness). No, I am not into antennas at all, but Wikipedia has an excellent article on dipole antennas. Curiously, my antenna happens to be “made in the USSR” and accepts 380V AC (take a close look… text/html 2013-07-23T13:52:17+02:00 https://openwall.info/wiki/people/solar/ardent-titan?rev=1374580337&do=diff In 1998, I was briefly given remote access to an Ardent Titan vector computer. IIRC, I was told that it had two 33 MHz MIPS CPUs controlling a vector unit with 8192-word vectors. The intent was to try to implement bitslice DES on it, as part of John the Ripper. Unfortunately, I did not approach the actual task until it was too late - I was told that the system had died. However, I did happen to try it out briefly and I saved some files from it, which I think are of historical value (which is… text/html 2020-06-02T16:07:35+02:00 https://openwall.info/wiki/people/solar/bio?rev=1591106855&do=diff I originally wrote the following text (or rather an older revision of it) on request from an Openwall client company, such that they could make their prospective client aware of who would be doing the security work on a specific project, and the text was reused in a similar fashion on several occasions. This is why I wrote it in third person, and this is why I keep it written that way. I generally prefer to write about things I do (with all the technical detail) rather than about myself, which… text/html 2024-02-06T23:09:58+02:00 https://openwall.info/wiki/people/solar/pocorgtfo?rev=1707257398&do=diff To comply with and support the samizdat license of PoC||GTFO, here are the journal issues so far: * [Issue 0x00] * [Issue 0x01] * [Issue 0x02] * [Issue 0x03] * [Issue 0x04] * [Issue 0x05] * [Issue 0x06] * [Issue 0x07] * [Issue 0x08] * [Issue 0x09] * [Issue 0x10] * [Issue 0x11] * [Issue 0x12] * [Issue 0x13] * [Issue 0x14] * [Issue 0x15] * [Issue 0x16] * [Issue 0x17] * [Issue 0x18] * [Issue 0x19] * [Issue 0x20] * [Issue 0x21] * [Issue 0x22] text/html 2021-03-04T14:05:58+02:00 https://openwall.info/wiki/people/solar/unique-password-count?rev=1614863158&do=diff Extract the available unique/total counts and ratios Let's use RockYou: $ wc -l r 32603387 r $ sort -uS 4G r | wc -l 14344391 $ shuf r > rs # Sanity check $ wc -l rs 32603388 rs # Apparently, "wc -l" didn't count the last line before "shuf" because there was no linefeed character after it.
