 22:17 <@matches> He has some books but they are mostly about economics
 22:18 <@matches> Would have been nice if he'd written something that says "I have invented floating point" but I guess not
 22:18 <@matches> That's only really of historical interest but it'd be nice
+--- Day changed Tue Apr 22 2014
+01:17 <@matches> Urgh looking at the git diff
+01:17 <@matches> I really have not accomplished much
+01:30 <@matches> Oooh, motsugo finally got to a number of intervals where long double is better than double
+11:56 < sulix> So it turns out that I've broken the open-source GL drivers.
+11:56 < sulix> They don't support one of the features ("primitive restart") we need when in compatibility mode.
+11:56 < sulix> So I guess now I've got to rewrite everything to use OpenGL 3.
+14:47 <@matches> ?
+14:48 <@matches> I should probably look more carefully at what the OpenGL stuff is doing nowdays
+14:49 <@matches> Downgrading to OpenGL 3 sounds drastic
+14:50 <@matches> Wait 3 is the OK one, 4 is the new one
+14:50 <@matches> 1 is the ancient one
+14:52 <@matches> I see pointer arithmetic...
+14:53 <@matches> banana would be furious
+14:53 <@matches> should be using std::super_ptr_unsegfaultable_arith
+14:53 <@matches> (I am not a fan of the smart pointers)
+14:55 <@matches> *indexData = 0xFFFFFFFF; // Primitive restart.
+14:55 <@matches> I do not know what is going on here :S
+14:58 <@matches> Ahh I get it now
+14:58 <@matches> Reading commit messages turns out to be useful
+15:04 <@matches> git blame for view.cpp reveals that I still own the opening braces on some things
+15:05 <@matches> That's about it :P
+15:06 <@matches> I'm going to keep looking at rounding errors and maybe have a better thing than calculating pi
+15:06 <@matches> As a bench mark
+15:07 <@matches> I might look at Paranoia
+15:07 <@matches> Although it was originally in BASIC
+15:07 <@matches> And ~7000 lines
+15:07 <@matches> With almost no whitespace characters
+15:07 <@matches> And totally no indents
+15:08 <@matches> I sometimes get the feeling people used to be smarter than we are now...
+15:08 <@matches> Then I remember that those people are ultimately responsible for the tools we use now
+15:15 < sulix> Speaking of tools we use now, I think I've just got the debug font code to not only randomly corrupt a varible, but also cause valgrind to crash.
+15:18 < sulix> Okay, we need to fix that makefile at some point.
+15:38 <@matches> make clean?
+15:41 <@matches> It's not actually swapping out main.cpp
+15:41 <@matches> It just doesn't have main.o in the link objects and has main in the $(BIN) target and the testers in the tests/% target
+15:42 <@matches> I guess that is swapping out main but MAIN is not being changed
+15:42 <@matches> derp
+15:45 <@matches> I think I fixed it?
+15:45 < sulix> Ah. Well, you've got a merge conflict to look forward to.
+15:45 <@matches> Not if I just NEVER COMMIT IT
+15:46 <@matches> I'm going to call your fix being right and mine being a horrible hack
+15:46 <@matches> Ok I pullsd some changes to graphics stuff, is that it or is there more?
+15:46 < sulix> I haven't fixed it, I've just gone and bu(gg|ff)ered up the font stuff.
+15:47 <@matches> So it's not meant to render unless something changes? But the debug font stuff is changing so it needs to keep rendering?
+15:48 <@matches> I see a lot of "Flushing Debug Font arrays"
+15:48 < sulix> The debug font stuff is separate from the whole view system.
+15:48 <@matches> That makes sense
+15:48 < sulix> It's just trying to fill up a buffer of quads with individual characters in it and then draws them when the buffer gets full.
+15:49 < sulix> One more step on the path of getting rid of all of the OpenGL 1.1 stuff.
+15:50 <@matches> Haha
+15:50 <@matches> git stash seems to think I modified graphicsbuffer.h and screen.h
+15:51 <@matches> git diff seems to think everything is identical
+15:51 <@matches> I'm just going to git reset the things I didn't actually change...
+15:52 < sulix> I do that far too often.
+15:52 <@matches> Oh there is a comment "//test" for testing the Makefile
+15:53 <@matches> And a comment "This isn't the Screen class?" where you copy/pasted the screen class description for the GraphicsBuffer class
+15:53 <@matches> I don't think they need to be preserved
+15:54 < sulix> Yeah, I should have got rid of that screen class bit by now.
+15:55 <@matches> Have a 2 line commit
+15:55 < sulix> The best kind.
+15:55 <@matches> I really need to cut back on the new line creep
+15:56 <@matches> It's like I can't add a line by itself without putting in extra whitespace 
+15:57 <@matches> Uh oh we've ran out of coffee here
+15:58 <@matches> I'm slightly scared by how much the graphics code has increased since I last actually understood how it worked...
+15:59 <@matches> Can you change those *vertexData to *(vertexData++) or is that considered even uglier
+16:03 < sulix> I thought of that, but given how much pointer arithmetic debugging I was going to do, I wanted it to be really obvious when the pointer was being incremented.
+16:03 < sulix> The plan is to have a nice AppendFloat() function or similar that will do this eventually.
+16:05 < sulix> Hmm: "Buffer usage warning: Analysis of buffer object 2 (bound to GL_ARRAY_BUFFER_ARB) usage indicates that the GPU is the primary producer and consumer of data for this buffer object. The usage hint supplied with this buffer object, GL_STATIC_DRAW, is inconsistent with this usage pattern. Try using GL_STREAM_COPY_ARB, GL_STATIC_COPY_ARB or GL_DYNAMIC_COPY_ARB instead.
+16:06 < sulix> Thanks nVidia.
+16:06 < sulix> Now if only we were using OpenGL 4.4 which got rid of buffer usage hints entirely.
+16:29 <@matches> Also I think you forgot the naming scheme :P
+16:30 <@matches> vertex_data
+16:31 <@matches> I will go back to pretending to be doing a literature review
+16:32 <@matches> Instead I will probably plot some graphs
+16:48 <@matches> So
+16:48 <@matches> If you look up "Handbook of Floating Point Arithmetic" on google (which lots of things like to reference these days)
+16:48 <@matches> You can download the entire thing
+16:48 <@matches> I was prepared to pay like $20 for it on amazon
+16:49 <@matches> Oh amazon doesn't sell actual books anymore though does it?
+16:49 <@matches> No they do have it
+16:50 <@matches> For $100...
+16:50 <@matches> I think I'll just stick with my free pdf thanks
+16:55 <@matches> "Handbook" being 579 pages...
+17:04 <@matches> I think if a textbook is citing blog posts we can probably get away with it
+17:05 <@matches> Oh my god I love this textbook
+17:05 < sulix> I was watching a conference talk last night when the presenter just said: "this technique is described on this guys blog. Here's a link."
+17:05 <@matches> "Table 1.1 gives the results obtained by compiling Program 1.1 and running on a Pentium4, using the GNU Compiler Collection and the Linux system"
+17:06 <@matches> [Complete C code for Program 1.1 follows]
+17:06 <@matches> None of this "Pseudo code" crap
+17:07 < sulix> Clearly we should get an extra 10% for every line of pointer arithmetic in our theses.
+17:07 <@matches> There'
+17:07 <@matches> s a problem here
+17:07 <@matches> How do I not make the entire literature review just paraphrased from this one text book
+17:08 <@matches> Mr Gullible and the Chaotic Bank Society!
+17:08 <@matches> It has stories!
+17:08 <@matches> Parents should read this textbook to their children
+17:09 < sulix> I'm pretty certain I know someone with a data structures and algorithms picture book...
+17:09 <@matches> That reminds me of a children's book I wrote about multithreading
+17:10 <@matches> I should probably scan it one day
+17:10 < sulix> Did it begin "Once upa timeon...
+17:10 <@matches> I think it did actually
+17:10 <@matches> Once upon a time there was a process who had a lot of work to do...
+17:11 <@matches> "I should probably scan it one day" - Why not TODAY!
+17:11  * matches goes searching
+17:16 <@matches> It is no where to be found
+17:16 <@matches> I distinctly remember going to throw it out and deciding not to, but not where it actually went
+17:27 <@matches> So maybe compiling a bunch of HFPA's examples using our Real type is a good way to make benchmarks
+17:27 <@matches> I don't know
+17:27 <@matches> My part of the project seems to move further and further away from the document formats thing
+17:27 <@matches> Maybe I'll try and compile the GPU Paranoia
+17:28 <@matches> Hah
+17:34 <@matches> It seems like whatever Mathematica does is what we should do
+17:35 <@matches> I wonder if wolfram is open about how Mathematica actually works
+17:35 <@matches> I don't think they are
+17:35 <@matches> The CQM lecturer for physics found a bug in Mathematica's number representation once that she showed us
+17:35 <@matches> Apparently she reported it years ago and it's still there
+17:36 <@matches> This segued nicely into why we should learn fortran
