16:33 * TheWatcher tries to work out the correct way to signal a write failure in a png write callback, suspects this is going to involve a tithe of hair
16:36
<@TheWatcher>
you'd think that calling png_error was sensible...
16:43
<@TheWatcher>
... oh, wait, it is, they just decided that actually documenting the fucking API properly is for wimps, and to shove "extern PNG_EXPORT(void,png_error) PNGARG((png_structp png_ptr,png_const_charp error_message)) PNG_NORETURN;" in the header
16:48
< simon__>
I'm trying to prove that p&q => p is a tautology.
16:48
< Namegduf>
"Work from the definition of =>" is all I remember of that one.
16:50
< Namegduf>
Hmm, wait, no. I think I misinterpreted.
16:50
< Namegduf>
Yeah.
16:51
< simon__>
if I could say (p&q => p) => (p => p), but I'm not sure and-elimination allows that in that way.
16:52
< Namegduf>
You want to derive, basically, p&q => p from p&q
16:52
< Namegduf>
If I've thought it through properly now.
16:53
< Namegduf>
Not reason with the implication itself.
16:53
< simon__>
I have this syntax: premise,premise,premise |- conclusion,conclusion
16:54
< simon__>
and the assignment reads "|- p&q => p" (which should be synonymous to "p&q |- p", which would be dead obvious to solve through and-elimination)
16:54
< Namegduf>
I think I went through this once, but I've long since forgotten it and my notes are presently in a locked filing cabinet. Sorry.
16:55
< simon__>
:P
16:55
< simon__>
'tis fine. I think some of this is hard ironically because it's simple.
17:04
< gnolam>
On this subject, I have now finally played "Ergo". Reiver (?) was right - the rule sheet is absolutely godawful (and what's worse, the updated rule sheet they have on their site /is still erroneous/). But it's an awesome idea, and it seemed (we played it under, err, sub-optimal conditions) pretty fun.
17:29
< RichardB>
simon__: doesn't "|- p&p => p" read as "'p&p => p' is a tautology"?
17:30
< RichardB>
Read literally, I mean.

22:51 * Derakon arghs, has just spent two hours trying to get the font rendering code he wrote for Jetblade to work for the microscope program without success.
22:52
<@Derakon>
All I get is black rectangles. :\
22:52
<@Derakon>
I'm pretty certain it has something to do with the transformation from PyGame surface to OpenGL texture, but I don't have the knowhow to debug that step.
22:52
<@McMartin>
Insufficient texture RAM?
22:53
<@Derakon>
Um, the work computer is something like four times more powerful than my home compy in every respect.
22:54
<@Derakon>
I can verify that the surface is generated properly using PyGame's get_at function. My attempts to write an equivalent function to download texture pixels from the video card indicate that every pixel there has the value [1, 1, 1, 1].
23:38
<@Derakon>
Unrelated: man, it's nice to use a pen that actually has a reliable ink flow~
23:38
<@Derakon>
I guess these pens aren't good for more than eight or nine months of heavy use~
23:45
<@Vornicus>
Okay three things left: 1. the thing that checks answers, 2. the thing that reports the results at the end, and 3. the countdown timer.
