As quoted from source (Creating the smallest possible PE executable): 1 Smallest possible PE file: 97 bytes Smallest possible PE file on Windows 2000: 133 bytes Smallest PE file that downloads a file over WebDAV and executes it: 133 bytes The files above are the smallest possible PE files due to requirements of the PE … Read more
After some time and serious consideration, I will post my own answer. There is nothing that matches TiddlyWiki. As for voluminous information, TW can pretty much handle it. (My early discouragements were due to malformed code.) Difficulty accessing information through the interface becomes an issue before any speed problems. This isn’t to fault the interface … Read more
Use readelf -a and objdump -x to inspect ELF files in preference to strings. Actually, all the GLIBCXX_* versions don’t apply to the entire library, but to each symbol (symbol versioning, see DSO-howto). So you can have e.g: std::char_traits<wchar_t>::eq@@GLIBCXX_3.4.5 and std::ios_base::Init::~Init()@@GLIBCXX_3.4 on the same library file. The fact that your program needs GLIBCXX_3.4.9 probably means … Read more
The intent is that a newline in a raw string literal maps to a single ‘\n’ character. This intent is not expressed as clearly as it should be, which has led to some confusion. Citations are to the 2011 ISO C++ standard. First, here’s the evidence that it maps to a single ‘\n’ character. A … Read more
int is a “most efficient type” in speed/size – but that is not specified by per the C spec. It must be 16 or more bits. int_fast16_t is most efficient type in speed with at least the range of a 16 bit int. Example: A given platform may have decided that int should be 32-bit … Read more
Update (Aug-2016): This question is no longer relevant, as msys2 now comes with cygpath in its installation. … I’ll summarize my research here. The cygpath equivalent in MSYS is to use this command: { cd /c/some/path && pwd -W; } | sed ‘s”https://stackoverflow.com/”\\|g’ The problem with this approach is that it requires existing path, e.g. … Read more
I got curious about this so decided to see what exactly is done by fmt.Println. http://golang.org/src/pkg/fmt/print.go If you scroll to the very bottom, you’ll see an if addnewline where \n is always used. I can’t hardly speak for if this is the most “cross-platform” way of doing it, and go was originally tied to linux … Read more
One of the example where std::ref is necessary: void update(int &data) //expects a reference to int { data = 15; } int main() { int data = 10; // This doesn’t compile as the data value is copied when its reference is expected. //std::thread t1(update, data); std::thread t1(update, std::ref(data)); // works t1.join(); return 0; } … Read more
Updated 16th of January 2019: Refined advice as tools evolve. I have used autotools before for a considerable amount of time. Currently I make intensive use of meson and cmake only when I need it. Some personal advice: for big teams, stick to CMake if you want to make use of the generators for XCode. … Read more
Mostly correct. Straight procedural interface is the best. (which is not entirely the same as C btw(**), but close enough) I interface DLLs a lot(*), both open source and commercial, so here are some points that I remember from daily practice, note that these are more recommended areas to research, and not cardinal truths: Watch … Read more
