02:51 <joseph_> teepee kintel: One thing that helped with GSoC last year was getting a general sense of when might be likely times to have a synchronous discussion on IRC. On a typical day during the coding period I expect that I'll be online approximately between 6pm UTC and 3am UTC.

12:55 <lf94> morning

13:06 <guso78> monring california!

13:07 <guso78> sorry canada :)

13:07 <lf94> lol

13:07 <lf94> hahahaha

13:07 <lf94> yea that's it x)

13:07 <guso78> yes its c......a so i put a HASH

13:14 <guso78> we got merged , hahaha ...

13:23 <lf94> B)

19:36 <guso78> can anybody tell me, whats wrong this small sort example:

19:36 <guso78> https://bpa.st/DSR6K

19:36 <guso78> IMHO the sort function meets the given critera: a<b and a>b must not be true at the same time

19:37 <guso78> it crashes reliable

19:42 <InPhase> guso78: It fails the asymmetry condition.

19:42 <InPhase> a<b and b<a must yield opposite results.

19:43 <guso78> InPhase, yes, ind1-ind2 =  - (ind2-ind1)

19:44 <guso78> can we assume that negate operator is , what human refer to as "opposite" ?

19:46 <guso78> InPhase , how would i write the test function better to satisfy the assemtry condition and sort the list ascending ?

19:48 <guso78> ahh i got it, return type is bool. this is different  from  c only  qsort function
