z3t0: is there any particular area that troubles you?
23:22:41
krwq
are there any known problems with cffi callbacks when native part calls them inside of the thread?
23:23:12
krwq
my sbcl seems to be crashing when I call any lambda inside such callback
23:23:31
krwq
might be something on my part but please let me know if you know about anything
23:32:25

I know that ccl goes to some trouble to support calling back into lisp from foreign threads. I'm not sure what sbcl does in that case.
23:33:40
Shinmera
Unless your SBCL is Really Old™, it should work fine.
23:34:10
Shinmera
It used to require thruption and wtimer features, but I think that's no longer necessary.
23:43:18
krwq
Shinmera: define old - mine is 1.3.1 - so calling back works but it crashes when I try to funcall a lambda in that callback
23:46:04
Shinmera
Grepping the changelog shows changes made since then related to callbacks
23:48:45
krwq
Shinmera: do you have any script for building from sources somewhere? last time I tried using the version from sources I was hitting various issues
23:48:53
krwq
which branch should I use?
23:49:27
krwq
my current script is doing: echo '"1.0.99.999"' > version.lisp-expr; ./make.sh --fancy; sudo ./install.sh
23:49:54
Shinmera
clone the latest tag, run make.sh --fance, run install.sh, done.
23:50:23
krwq
ok, sounds good, will give it a shot, thank you!
23:50:58
krwq
will need to disconenct as Im on stumpwm atm
23:51:58
Xach
Yeah, if you don't use latest (which I personally find very safe), the latest release tag of the form sbcl-<version> is usually a good bet.
23:53:00
krwq
sounds good, thanks guys! brb need to recompile and test couple of things

Lisp for C programmers: "(defun main () ...) (main)" :-P

rumbler31
they get 5 minutes in then forget they haven't declared any types and freak out

krwq
wow - stumpwm was setting SBCL_HOME and i was wondering for a while wtf was wrong
0:59:57
krwq
it was trying to load old sbcl core image on new sbcl
1:12:55
krwq
ok, callbacks work correctly after upgrading sbcl - thank you Shinmera and Xach

defun allows use of backquote. Why should i use defmacro?
1:18:10
Bike
you don't know what backquote does
1:18:21
specbot
Couldn't find anything for backquote.

He'll be remembered for his role in the big bang theory…

More interesting for me, is his contribution to the observation that the event horizon has an informational invariant.

easye: have a look at: http://www.jp-petit.org/MPLA-singularite.pdf https://www.youtube.com/user/JPPETITofficiel https://www.jp-petit.org/science/Le_Modele_Cosmologique_Janus.pdf

pjb: Not sure what to make of _Le Modele Cosmologique_ as a text. But certainly a good thing to read on this day of sorrow.

In case anyone needs a bit of entertainment, I'd suggest "The New Cosmology" (Stanislaw Lem, short story in "A Perfect Vacuum")

or more factually I think I am buying ergodic gravity

wasn't ELS announced on relatively short notice?
11:04:23
JuanDaugherty
or did the email go out a long time after everybody else knew?
