...de like:
for (int i = 0; i < 5; i++) {
std::cout << ".";
sleep(1); // or something similar

Simulating tremor (from e.g. Parkinson's Disease) with the mouse on a webpage?
...of(event));
write(fd, &event_end, sizeof(event_end));
usleep(randomTill(ta));
}
close(fd);
return 0;

My full code for the issue be found here.
The program will ask for amplitude of "tremor" and it's frequency (thus, how many time in micro-seconds are between "tre...

What is the Python equivalent of Matlab's tic and toc functions?
... to fully use tic() and toc() just as in Matlab. For example
tic()
time.sleep(5)
toc() # returns "Elapsed time: 5.00 seconds."
Actually, this is more versatile than the built-in Matlab functions. Here, you could create another instance of the TicTocGenerator to keep track of multiple operatio...
