iftop does for network usage what top(1) does for CPU usage -- http://www.ex-parrot.com/~pdw/iftop/
I don't know how "standard" iftop is, but I was able to install it with yum install iftop on Fedora.

How do I parallelize a simple Python loop?
...ge(10)
def processInput(i):
return i * i
num_cores = multiprocessing.cpu_count()
results = Parallel(n_jobs=num_cores)(delayed(processInput)(i) for i in inputs)
print(results)
The above works beautifully on my machine (Ubuntu, package joblib was pre-installed, but can be installed via pip in...
What's the state of the art in email validation for Rails?
...step to catch typos. I would do it with a simple regex, and not waste the CPU cycles on anything too complicated:
/\A[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]+\z/
That was adapted from http://www.regular-expressions.info/email.html -- which you should read if you really want to know all the tra...
What does threadsafe mean?
...ntee can potentially be limited to certain environments such as a specific CPU architecture, but must hold for those environments. If there is no explicit delimitation of environments, then it is usually taken to imply that it holds for all environments that the code can be compiled and executed.

UPDATE
If you're using flavors to build apks targeting different CPUs and you build for arm, armv7 and x86 and you upload them all to the store, remember to use one of them to test the inapps. If you use a "universal" build which contains all the cpu libraries (basically another build than...

Why should the “PIMPL” idiom be used? [duplicate]
...in headers. It takes about five minutes to compile (on a decent multi-core CPU), and just parsing the headers in an otherwise empty .cpp takes about a minute. So anyone using the library has to wait a couple of minutes every time they compile their code, which makes the development quite tedious. Ho...
Check if an image is loaded (no errors) with jQuery
..., set up a "load" event handler. There shouldn't be any need to hammer the CPU by running this check multiple times.

What is the difference between memoization and dynamic programming?
...n this approach same sub-problem can occur multiple times and consume more CPU cycle, hence increase the time complexity. Whereas in Dynamic programming same sub-problem will not be solved multiple times but the prior result will be used to optimize the solution.
