Th[4~esis? Illuminati? +11:34 < matches> "Haters gonna hate" would be me hating the thesis, but the thesis being an inanimate and currently purely digital object would be unable to shake itself +11:35 < matches> According to the comments Taylor Swift is in the illuminati +11:35 < sulix> The only shaking I can imagine is the solemn shaking of heads. +11:35 < matches> :( +11:35 < Pommers> Or +11:36 < Pommers> Does your thesis hatre you, hence it's not happening +11:36 < Pommers> and therefore you need to shake it off? +11:36 < matches> Perhaps the clue is in the name, in that we need to Swiftly apply Taylor series to things +11:38 < sulix> matches: That is the only consistent interpretation. +11:38 < matches> I regret catching up on 6 weeks of lectures instead of working on the thesis +11:40 < matches> http://www.irregularwebcomic.net/374.html +11:40 < sulix> http://phdcomics.com/comics/archive.php?comicid=1749 +11:42 < matches> Back to it I guess +11:42 < matches> By which I mean back to spending 30 minutes mentally preparing myself to go back to it +11:43 < Pommers> While you relax +11:43 < Pommers> You could fix NTP on your laptop +11:46 < sulix> better still, set the time to three days ago so that you have more time to work on the thesis. +11:47 < Pommers> Thats's a good idea! Just avoid anything that relies on time +11:49 < sulix> The number of sudden thoughts about much better ways to do this project is slightly terrifying. +12:44 < sulix> /me suspects he's deleted more than he's written. +13:02 < sulix> Someone's looked at quadtrees for "infinite bitmaps": http://programmers.stackexchange.com/questions/104609/infinite-bitmap +13:44 < sulix> Knuth apparently does not like the term "mantissa". He has quite a rant about it and now I'm feeling guilty for using it. +13:47 < matches> Let's face it, Knuth won't read our work, and if he does, he won't like it +13:48 < sulix> I had a nightmare where Kahan was berating me for not understanding floats. +13:49 < matches> You don't even need to write about floats? Do you? +13:49 < matches> Also, should I be urgently producing graphs of how slow rationals are +13:50 < matches> I have 6662 words, but this is really not good +13:51 < sulix> I'm sort-of leaving the "results" section blank at the moment. +13:51 < matches> Wait but what else do you need? +13:51 < matches> Lit Review should be done* +13:52 < matches> There is a "Methods" chapter which I'm a bit embarressed about +13:52 < sulix> Also, I should push the "speed up everything because it was dodgy renderrange code that was taking >90% the time" fix at some point. +13:52 < matches> How badly would pulling break everything... +13:52 < sulix> I've been writing up how the quadtree works, and fixing up the lit review, intro, gpu float bits, etc. +13:53 < sulix> Well, I don't think I've been brave enough to push yet, but probably it will break everything. +13:53 < sulix> Though, with some small amount of luck, it should still compile. +13:56 * sulix has pushed. Time to warm up your "git revert" commands. +13:57 < sulix> Also I need to write up about how rationals can represent more things than the quadtree, which can only represent binary fractions. +14:18 < matches> "A naive approach would be to simply replace all floating point operations with arbitrary precision operations, and this is in fact what we did before we realised how stupid that was" +14:21 < sulix> I was going for "A naïve approach would be to simply replace all floating point operations with arbitrary precision operations, and unlike the quatreethulu, that does actually work." +14:21 < matches> How do you get the ï in LaTeX +14:22 < sulix> \"i +14:22 < matches> Thankyou +14:25 < matches> Is there a good reference I can cite for how shaders work... +14:25 < matches> I really don't want to or have the space to explain the OpenGL API +14:25 < sulix> The OpenGL spec? +14:25 < matches> I guess +14:25 < sulix> Or ARB_vertex_program / ARB_shader_program +14:25 < sulix> s/shader_program/fragment_program +14:47 < matches> You know I am linking to the git repository in my report +14:47 < matches> The one with all the "My eyes, they burn!" commit messages... +14:48 < matches> I figured that the markers assuming there wasn't version control was marginally worse than them reading my commit messages +14:48 < matches> But only marginally +14:49 * sulix wipes some nervous sweat from his brow. +14:50 < Pommers> What did you do for commit messages? +14:50 < matches> Usually stuff to the effect of "This code is awful" +14:50 < matches> "I didn't even design this!" +14:50 < matches> Etc +14:51 < sulix> Pommers: cover your eyes: http://git.ucc.asn.au/?p=ipdf/code.git;a=shortlog +14:52 < sulix> My favourite is "A Song of Floodfills and Segfaults" +14:52 < Pommers> haha +15:11 < sulix> matches: Any idea why "bezier.h:61:20: error: call of overloaded ‘Abs(Gmprat)’ is ambiguous" +15:13 < sulix> Also: "rect.h:21:13: error: no match for ‘operator<<’ (operand types are ‘std::basic_ostream’ and ‘const IPDF::Rational’)" if I try Rational +15:37 < matches> Aaaah +15:37 < matches> It wasn't ambiguous when I last used it! +16:03 * sulix squirms nervously. +16:06 < matches> I finally made the performance test graphs +16:06 < matches> They are kind of dodgy +16:07 < sulix> Ooh... show me. +16:13 < matches> http://szmoore.net/ipdf/sam/figures/time.pdf +16:13 < matches> http://szmoore.net/ipdf/sam/figures/memory.pdf +16:13 < matches> It's using eye_of_the_rabbit.script +16:14 < matches> It keeps track of how much memory is used for the View width +16:14 < matches> And how long it takes to do each cycle that involves adding 3 rabbits seperated by 1e-3 or whatever it was +16:14 < matches> A totally arbitrary test but hey, the graph is linear +16:15 < matches> I'm pretty fed up with this project at this point +16:15 < matches> Words are on the page +16:16 < matches> It's amazing how much less you have to write when you remove the "TODO: I really should explain this properly" +16:19 < sulix> Those are with the Gmprat for path bounds, doubles? for beziers? +16:21 < matches> Gmprat for path bounds +16:21 < matches> Not really much point doing it for anything else +16:21 < matches> Since anything else won't render the images correctly +16:21 < matches> I guess I should do it for doubles as well +16:22 < matches> Actually doubles would be able to render that particular script correctly +16:22 < matches> For a long time +16:23 < sulix> The quadtree can render it correctly until there is more than one rabbit. +16:23 < sulix> Also eye_of_the_rabbit is cpu rendered by default, no? +16:24 < matches> Yeah I changed it to make that test +16:24 < sulix> Okay. +16:24 < matches> I'll run it for mpfr-1024 path +16:24 < matches> I've had enough of having to tweak things to recompile the software... +16:25 < matches> So I'm limited to the binaries I already have and they have a habit of sigfpe'ing +16:26 < matches> Oh, it was also done with the window hidden +16:26 < sulix> By choice or by fglrx? +16:26 < matches> By choice +16:31 < matches> Urgh this project is dumb +16:31 < matches> I really don't want to have to repeat my final year project :S +17:17 < matches> How do you like being referred to as "Gow" +17:17 < matches> Also it's been an hour or so without me saying this project is silly +17:17 < matches> So I'll say it again +17:18 < matches> I ended up putting the Circles on CPU/GPU in my "Lit Review" part... +17:18 < matches> Because it just fit a lot better underneath the section that was actually talking about it +17:18 < matches> Rather than in the results +17:19 < matches> "By the way we did some circles too" +17:19 < matches> I feel like I should say something snarky about the naive method not being worthy of publication... +17:19 < matches> That might be a bad idea +17:29 < matches> "Hi all, No doubt you are busy preparing your final report..." +17:29 < matches> AAAAAHHH +17:30 < matches> I don't know, there's only so much you can polish a turd.. +17:30 < matches> Holy shit how do I have 40 references +17:30 < matches> I guess there was that "Look I read about GPUs [10 references]" paragraph +17:31 < matches> Should I mention the arbitrary precision on GPU stuff +17:31 < matches> Blargh +17:41 < matches> "The main body of the report should be between 6,000 and 8,000 +17:41 < matches> words excluding appendices. (i.e. from the beginning of the +17:41 < matches> Introduction to the end of the Conclusions/Future work section)." +17:41 < matches> Finally found the word limit +17:41 < matches> Dammit +17:41 < matches> Here I was aiming for 6000 maximum... +17:44 < matches> I can stick in the pointless sections about "Pixels or Perish" I guess +17:44 < matches> Distract them with pretty pictures +17:47 < matches> Takes me up to 46 references... +17:47 < matches> And 6972 words +17:47 < matches> Done +17:48 < matches> Submit +18:21 < sulix> I think your thesis is significantly better than mine. +18:22 < sulix> Mostly because it has more results and less "TODO" +18:26 * sulix seeps into a 20 minute come. +18:26 < sulix> s/come/coma +18:26 < sulix> (The state of my brain is becoming more and more evident) +18:55 < matches> (The trick is to delete the TODOs) -- 2.20.1
