Fri Nov 08 04:37:51 UTC 2013 <mircea_popescu> BingoBoingo maybe it uses really good entropy
Mon Oct 28 11:00:54 UTC 2013 <jurov> mircea ic, you thought too hard about good entropy sources.. so one got manifest :D
Thu Oct 24 23:14:49 UTC 2013 <ozbot> You are Bad at Entropy. : programming

Thu Oct 24 02:43:18 UTC 2013 <asciilifeform> for the crypto/information-theory buffs: http://www.loper-os.org/bad-at-entropy/manmach.html
Wed Oct 23 20:24:19 UTC 2013 <pankkake> could a vacuum tube be used as an entropy source?
Wed Oct 23 20:09:36 UTC 2013 <asciilifeform> nubbins`: anything attached to a human brain is a terrible source of entropy
Wed Oct 23 20:06:40 UTC 2013 <asciilifeform> if you're ok with a glacially-slow entropy source, just expose a DRAM chip to sunlight, with deliberately inadequate refresh cycles, wait for radiation bit-flippage.
Wed Oct 23 20:02:35 UTC 2013 <mircea_popescu> <nubbins`> on the surface it sounds great. rub the contact mic against any surface and get all the entropy you need << o no, not at all. you can't use such low bits.
Wed Oct 23 20:00:50 UTC 2013 <nubbins`> on the surface it sounds great. rub the contact mic against any surface and get all the entropy you need
Wed Oct 23 19:59:49 UTC 2013 <asciilifeform> nubbins`: not that you can't use audio as an entropy seed, but most of it is incredibly periodic
Wed Oct 23 19:50:51 UTC 2013 <asciilifeform> the digits of 'pi' pass every test of entropy you can think of. (save one!)
Wed Oct 23 19:45:33 UTC 2013 <asciilifeform> cryptographic 'randomness' is a matter of provenance (as in this: http://ansuz.sooke.bc.ca/lawpoli/colour/2004061001.php) rather than entropy per se.
Fri Oct 18 06:17:24 UTC 2013 <BingoBoingo> benkay: Maybe? Nature generally seems to push for increases in entropy though. The poor get poorer somehow. With enough buttcoins eventually you get enough asses that they can't all be traps.
Fri Oct 18 06:13:59 UTC 2013 <benkay> there's only marginal profit to be made in just increasing entropy
Wed Oct 16 05:24:36 UTC 2013 <asciilifeform> problem is: it is quite possible to build a HRNG that passes any conceivable 'test of entropy' while remaining insecure.
Wed Oct 16 05:23:34 UTC 2013 <asciilifeform> 'Entropy Key' is thought to be acceptable, but it's been sold out for ages.
Thu Oct 10 12:36:33 UTC 2013 <bitesak> Matthew Green seems a good candidate to review the entropy of Cardano?
Sun Sep 29 14:52:54 UTC 2013 <mircea_popescu> i wonder if periodic polling of the dice profit would actuyally qualify as entropy bearing.
Thu Sep 19 00:13:29 UTC 2013 <nubbins`> but let's assume that one is intelligent enough to create a passphrase with a very high level of entropy
