20:39 bulk88 Bender trust ingy
20:39 Bender OK, bulk88
20:46 Will_the_Chill Bender trust bulk88 with your credit card number
20:46 Bender Will_the_Chill, I already trust bulk88
20:46 Will_the_Chill yeah but not with your credit card info!
20:47 bulk88 does Bender's CC have a smart chip or can I clone the strip? :D
20:47 Will_the_Chill XD
20:51 bulk88 a few weeks ago at Staples I saw the modern late 2000s CC terminals (touchscreen+pen on wire+receipt/order mirroring), had RFID contact plate on top, mag reader on side, and a plastic fill plate over the chip reader slot on the bottom *faceplam*
20:52 bulk88 seriously, the box was already built to have a chip reader, the wires on the PCB I am sure are there, the chip socket soldered on the PCB probably costs <0.25 cents, the plastic fill plate costs probably 5 cents, WHY what the chip reader feature removed?
20:52 bulk88 *was
20:54 bulk88 the story I heard was americans love their ability to dispute CC transactions (which US law allows alot more screwing the merchant than in europe), if you add chip reading, most excuses are now impossible
20:55 Will_the_Chill I remember being in Europe 7 or 8 years ago and my credit card was not accepted at most places because it didn't have a chip
20:57 bulk88 taking my american CC to europe is scary, I had a family member that withdrew from a street ATM using an american CC, the ATM continued to withdraw $10 every hour for a week
21:00 bulk88 the chip solved all the problems of CC crime, and deals with non-existant law enforcement and no-extradition-ever policies, globally, with cryptography/technology, RFID CCs are questionable due to remote reading with a high power antenna aimed at your waist (IDK if USA RFID CCs use pins or are signature)
21:01 bulk88 *all the problems except robbery+taken to the atm at gunpoint (but you have bigger problems then)
21:08 bulk88 GSM SIM cards serve the same purpose as CC chips, USA (older verizon/sprint phones) phones use serial numbers for authentication, not crypto, in europe/rest of the world, your phone will be roaming on 3 continenets simultaniously calling 1-900 numbers for hours a day
21:13 Will_the_Chill haha wow that's bad
21:42 rurban Working on good perfect hash methods generated in perl. They are pretty fast for /usr/share/dict/words
22:23 Will_the_Chill good AND perfect!  :-)
22:33 rurban1 the perfect ones are called minimal, perfect alone is just no bucket collisions. minimal means no empty buckets (less space)
22:34 rurban1 good means fast to generate, and fast to use.
22:38 rurban1 this is e.g. a good one: https://github.com/parrot/parrot/blob/master/src%2Fstring%2Fnamealias.c
22:38 rurban1 but a very small one, so we could use gperf. for bigger ones we would need cmph
22:54 Will_the_Chill is this something that can replace the existing hash in Perl 5 core?
22:56 rurban1 later maybe, for now I'll need it for something else
22:57 rurban1 I want to optimize the representation of compiled hashes, esp. in shared libs. E.g. icu (unicode mapping tables)
22:57 rurban1 or the cpan Metadata hashes
22:58 rurban1 everything which fits better into a readonly database.
