It wouldn’t. The two fundamental issues with global variables is simply cluttering the namespace, and the fact that “no one” has “control” over them (thus the potential collisions and conflict with multiple threads). The “globals are bad”, like pretty much every other computer programming idiom is a guideline, not a hard and fast rule. When … Read more
You are looking for Multi-Process Mode for gdbserver and set remote exec-file filename
Using simple brute force is sometimes good. I think precalc all shifted values of the word and put them in 16 ints so you got an array like this (assuming int is twice as wide as short) unsigned short pattern = 1234; unsigned int preShifts[16]; unsigned int masks[16]; int i; for(i=0; i<16; i++) { preShifts[i] … Read more
Have you considered HDLC or SDLC? There’s also LAP/D (Link Access Protocol, D-Channel). Uyless Black’s “Data Link Protocols” is always nearby on my bookshelf – you might find some useful material in there too (even peruse the TOC & research the different protocols)
As I was the original author of the comment, I have to add a very important issue you did not mention in your question. That is, the original was about an embedded system. Presuming this is a typical bare-metal system with integrated Flash, there are very important differences from a PC on which I will … Read more
This might help: In-place matrix transposition. (You might also have to do some mirroring after the transposition, as rlbond mentions).
We use python in quite a lot of embedded boards with ARM processors and 16 MB of RAM (running linux). It works really well and is really easy to make custom code quickly – one of the strong points of python. As for reliability of the code – we try to have 100% test coverage. … Read more
It’s not exactly static initialization, but still, give it a try. If your compiler doesn’t support C++0x, I’d go for std::map’s iteration constructor: std::pair<int, std::string> map_data[] = { std::make_pair(1, “a”), std::make_pair(2, “b”), std::make_pair(3, “c”) }; std::map<int, std::string> my_map(map_data, map_data + sizeof map_data / sizeof map_data[0]); This is pretty readable, doesn’t require any extra libraries and … Read more
Have you taken a look at the HTTPClient on mbed? Looks like there are lots of forks of an original from a few years ago that wasn’t maintained. I haven’t used this… http://mbed.org/users/WiredHome/code/HTTPClient/
Like 1800 INFORMATION said, avoid polling; subscribe to events and wait for them to happen Update window content only when necessary – let the system decide when to redraw it When updating window content, ensure your code recreates as little of the invalid region as possible With quick code the CPU goes back to deep … Read more
