Is there an equivalent to CTRL+C in IPython Notebook in Firefox to break cells that are running?
...it useful. This python script will find any jupyter kernel using more than cpu_threshold CPU and prompts the user to send a SIGINT to the kernel (KeyboardInterrupt). It will keep sending SIGINT until the kernel's cpu usage goes below cpu_threshold. If there are multiple misbehaving kernels it will p...
Task vs Thread differences [duplicate]
...now it will be a separate thread, rather than executing on the thread pool etc.
Task is more than just an abstraction of "where to run some code" though - it's really just "the promise of a result in the future". So as some different examples:
Task.Delay doesn't need any actual CPU time; it's jus...

...CPU architecture and optimization. For example, things you know about the fetching mechanism, caching, etc. This is supposed to be transparent to the developer, but the fact is that it is not, that's why compiler writers can optimize.
Certain hardware level accesses are only possible/practical via a...
Why do stacks typically grow downwards?
I know that in the architectures I'm personally familiar with (x86, 6502, etc), the stack typically grows downwards (i.e. every item pushed onto the stack results in a decremented SP, not an incremented one).

How do I return multiple values from a function? [closed]
...g (or too simplistic).
Returning a dictionary with keys "y0", "y1", "y2", etc. doesn't offer any advantage over tuples. Returning a ReturnValue instance with properties .y0, .y1, .y2, etc. doesn't offer any advantage over tuples either. You need to start naming things if you want to get anywhere, a...
