Hi, Why does this print garbage instead of exiting my program gracefully? I use system calls this way on BSD, and I wonder what would I need to make it work in Linux. int main(int argc, char **argv) { __asm ("movq $1,%rax; movq $0,%rdi; syscall"); /* exit(0) ? */ return 0; } Thanks. ...
I would like to collect here what happens when you run an executable on Windows, Linux and OSX. In particular, I would like to understand exactly the order of the operations: my guess is that the executable file format (PE, ELF or Mach-O) is loaded by the kernel (but I ignore the various sections of the ELF and their meaning), and then y...

I want to log how long something takes in real walltime. Currently I'm doing this: startTime = time.time() someSQLOrSomething() print "That took %.3f seconds" % (time.time() - startTime) But that will fail (produce incorrect results) if the time is adjusted while the SQL query (or whatever it is) is running. I don't want to just benc...
I am developing c on linux using vim and debugging using ddd. However I find that ddd performs very poorly at scrolling on this machine so its sometimes very frustrating to use.

I've been using FreeMarker for a little while now, but there's one glaring piece of functionality that is either missing or I just can't figure out (I hope the latter!). If you pass cfg.getTemplate() an absolute path, it just doesn't work. I know you can specify a template directory, but I can't afford to do that, my use case could dea...
