I don't have the slightest idea, but I found the source code, and it's giving me a headache e: jesus, had almost forgotten about the k-means++ color reducer, the bespoke monochrome converter and all the other insanity e2: I guess it's the kind of C# code a C++ programmer would write, pining for C++ template functions the whole time e3: iirc the microsoft resource compiler hated icons with embedded pngs anyway, and I had to use windres from mingw, and link the icon as a separate .res file e4: I'm a bad programmer is the moral hackbunny fucked around with this message at 10:36 on Jan 30, 2015 |

Dessert Rose posted:bounds checks will kill your performance it was totally unnecessary in my case, but I used to have an obsession with zero-copy, and Bitmap.LockBits in read-only mode could guarantee that (... if GDI+ used a DIB section for that bitmap). I also have an irrational prejudice against getpixel/setpixel methods since reading that article on how solitaire used to take 100% cpu on nt 3.1 with its victory animation, because it used getpixel/setpixel instead of manipulating bits in memory

I used unsafe once because I had a very fast c++ library heck borderline application but I wanted to use something pleasant and not painful to set up and tear down all the data to it and also manage the parallelism and so forth so I used c# for the bits it was great at and c++ for the bits it was great at and that program was my magnum opus

Dessert Rose posted:bounds checks will kill your performance I thought the .NET JIT did a really good job hoisting or eliminating bounds checks these days. The bounds check itself is pretty cheap and very friendly to modern (x64) architectures as well; IIRC it's a fused compare/jump that's easily predicted and plays nicely with speculative execution. it used to be that you wanted to use certain patterns in your loops to trigger the elimination, but I think that's much more flexible in modern CLR too. but yeah, I'd understand if it were a high-throughput pipeline and pinvoking to a tuned C++ library wasn't an option. it didn't sound like that was the case.

Shinku ABOOKEN posted:can't find your podcast I'm frequently invited to talk (and mostly complain) on Mostly Erlang. I don't particularly recommend it unless you're really into hearing people spend one hour talking about pet libraries in Erlang and stuff like that. I'm kind of amazed it gets listeners at all in the first place.

I haven't listened to it but I know people I don't hate who like it. i used to like radiolab a lot when i listened to it in the car while driving. i was highly distracted (by the task of driving) so all the weird voiceovers and jump cuts were entertaining listening to the same content in my living room, with my full attention, it's extremely irritating

I haven't listened to it but I know people I don't hate who like it. it's just up its own rear end. it's guts are pretty good so it's not a bad rear end to be in but it can get annoying. 99% invisible is the same way sorta except i can actually tolerate radiolab. 99% is usually about something interesting but i cannot stand roman mars. everything else has kinda been a letdown. i like probably science but i also hate it a lot because while it's sometimes good, othertimes it's just redditors talking. the bugle is the only thing i am 100% behind.

I don't know if a programming podcast isn't a flawed premise because I like to look at examples if you're just talking about programming without scribbling and showing code snippets it's probably boring shallow stuff
