<joolean>Howdy, #guile!

<joolean>What are the Cool Kids (i.e., people on master) doing to inspect SCMs in GDB these days? It looks like gdb_print was removed.

<joolean>Specifically, it looks like wingo removed it with a5d0c1

<nalaginrut>morning guilers~

<nalaginrut>I think Content-Length:0 bug was fixed in master, right? I know it's fixed in stable-2.0

<nalaginrut>if-none-match can't accept a normal string as etag?

<nalaginrut>maybe it's a bug

<dsmith-work>Hey hey

<dsmith-work>stis__: Hej!

<wingo>heya dsmith-work

<stis__>tja dsmith-work

<ijp>./stdio.h:1034:1: error: 'gets' undeclared here (not in a function) _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead"); ^

<ijp>never seen that one before

<ijp>maybe I'll clear my config cache and try again

*stis__ is feeling the power of mother nature (thunder and lightning)

<ijp>yeah, seems it was just a stale cache

<ArneBab>stis__: here it’s great, too!

<ArneBab>I wrote a script which uses binomial expansion, and when my numbers get too big, it returns +nan.0

<ArneBab> http://paste.lisp.org/display/143195

<ArneBab>do you know how I can make it cope with huge numbers?

<ArneBab>to test:

<ArneBab>wget http://paste.lisp.org/display/143195/raw; guile -L .

<ArneBab>then

<ArneBab>(use-modules (spielfaehig))

<ArneBab>(spielfähig 0.02 4000 70)

<ArneBab>easier: wget http://paste.lisp.org/display/143195,1/raw -O spielfaehig.scm; guile spielfaehig.scm

<lloda>.02 is inexact, so it'll be done in floating point. Try 1/50 or #e.02 (?)

<ArneBab>I’ll try that, thanks!

<ijp>sounds slow

<ArneBab>it is, yes

<ArneBab>it was originally intended for n up to 20 and min_players up to 9

<ArneBab>and p around 0.9

<ArneBab>but it proved to be extremely useful for quick probability checking…

<lloda>if the big numbers only appear in the intermediate steps, there should be a better way to compute that, but I don't know

<ArneBab>I’m now using exact math

<ArneBab>first observation: the memory usage rises

<ArneBab>with floats: 14MiB, with (/ 1 50) it’s already at 30MiB.

<ArneBab>(which still is very little memory)

<ArneBab>something weird happened there… I got a huge number in return

<ArneBab>seems that it was just the exact representation

<ArneBab>which I could not parse by eye

<ArneBab>(exact->inexact (...)) helped

<ArneBab>thanks a lot!

<ArneBab>working version: http://paste.lisp.org/display/143195#2

<ArneBab>here’s the conclusion from that: http://draketo.de/english/exact-math-to-the-rescue

*wingo found a nice bug in soft ports

<civodul>howdy wingo!

<civodul>wingo: what kind? :-)

<wingo>civodul: not a crasher :)

<wingo>source locations at the repl are almost always wrong

<wingo>i have a patch i'm testing

<wingo>greets btw!

<dsmith-work>wingo: That last update fixed the last error I saw. But added a new one. coverage.test now fails.

<civodul>oh, location info that gets lost

<wingo>dsmith-work: yep, working on that

<dsmith-work>wingo: Cool

<wingo>in a local branch i patched the reader to add source info to the spine of lists, not just the head

<wingo>maybe that will give us source info for lone symbols and immediates

<wingo>tough to plumb it through psyntax though

<civodul>heh

***EvilTheCat is now known as Turkish_pizza

<dsmith-work>wingo: Gonna give a talk at http://lists.gnu.org/archive/html/guile-user/2014-07/msg00018.html about guile 2.{1,2}, elf, and the rest? ;-)

*dsmith-work ducks before wingo can swing

<civodul>and at http://lists.gnu.org/archive/html/guile-user/2014-06/msg00005.html !

<civodul>argh

<civodul>dsmith-work: you'll have to ping him again :-)
