https://www.swansontec.com/sregisters.html I wrote this article for an online magazine called Scene Zine . Scene Zine caters to the Demo Scene, which is an digital art community dedicated to pushing the limits of computers through a mix of music, art, and computer programming. A particular category of demoscene productions, 4K intros, focus on the final production's raw file size. The goal is to put as much high-quality music, graphics, and animation as possible into only 4096 bytes. Doing this requires highly-specialized size optimization techniques, since 4096 bytes is less space than two

The task is to make an efficient gcd algorithm of two positive integers m and n using his notation theta[j] , phi[j] , b[j] and a[j] where theta and phi are strings and a and b - positive integers which represent computational steps in this case. Let an input be the string of the form a^mb^n . An excellent explanation of Knuth's algorithm is given by schnaader here . My question is how this may be connected with the direction given in the exercise to

With *.mp3 files this ended up not being too much of an issue, mainly thanks to the example provided here : static QImage imageForTag(TagLib::ID3v2::Tag *tag) { TagLib::ID3v2::FrameList l = tag->frameList("APIC"); QImage image; if(l.isEmpty()) return image; TagLib::ID3v2::AttachedPictureFrame *f = static_cast<TagLib::ID3v2::AttachedPictureFrame *>(l.front()); image.loadFromData((const uchar *) f->picture().data(), f-

Lower android versions work fine and devices of other manufacturers with Android 5 work fine too. I don't have any device where I could reproduce the issue, so I can't bisect. I am trying to deduce what could be wrong from the crash report and from list of changes since my last working version (which is unfortunately long). All the crash reports look like this (just the addresses slightly vary

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I have an app on the Play Store, it has an IntentService that does some work when the app starts, and it's causing native crashes on Android 5.0. This service just scans the assets folder for app updating purposes. Specifically, this crash seems to happen on Samsung S5 after the ugrade to Lollipop, but I don't know if it's strictly related to that device, as it's an Italian app and here that's still the only widely diffuse (i.e. that I know of) device that's getting Lollipop. However, I tried it on the emulator, with stock Android 5, and it
