05:54 <tankf33der> morning

05:54 <tankf33der> i did this one

06:16 <Regenaxer> Impressing how productive you are!

06:16 <Regenaxer> morning btw

06:17 <Regenaxer> The final (T) in 'cond' can be omitted

06:18 <Regenaxer> Looks all very good!

06:19 <tankf33der> omitted?

06:19 <tankf33der> hm

06:19 <Regenaxer> yes, it is a no-op

06:19 <Regenaxer> 'cond' returns NIL if no clause matches

07:02 <tankf33der> fixed. i dont understand how it happened.

07:03 <Regenaxer> No big thing

07:04 <Regenaxer> Happens. Sometimes I reserve such construct for later and then forget to remove

11:23 <tankf33der> i have idea: lets take english words and find&list collisions for djb, xxhas, siphash hases.

11:26 <Regenaxer> collisions of words with hashed words?

11:27 orivej has quit [Ping timeout: 245 seconds]

11:32 <tankf33der> yea, list words with the same hash.

11:33 <Regenaxer> Interesting idea, but for what purpose?

11:38 <tankf33der> just for fun :(

11:39 <Regenaxer> Could be a large 'idx'

11:40 <tankf33der> yea, i will start with djb hash, it was root of idea.

11:41 <Regenaxer> Cool

19:06 <tankf33der> https://git.envs.net/mpech/tankf33der/src/branch/master/collisions

19:06 <tankf33der> ~1.3secs for djb2 and xxhash32 in ~1.9secs

20:13 <Regenaxer> What does that mean?

20:14 <tankf33der> picolisp and idx is fast.

20:14 <Regenaxer> Great :)

20:14 <Regenaxer> Thanks!

20:15 <tankf33der> build idx tree in 370K items with collision check took ~1sec.

20:15 <Regenaxer> cool

20:18 <tankf33der> and result of djb and xxhash is the same in general, but xxhash sososo heavier.

20:19 <Regenaxer> ok
