Watcher for long computations

[albop]

I have been using this code on my server to track long computations: https://gist.github.com/albop/8c94e8694369474f7c85 . It is used to track long computations and send an email when they are finished. It uses a context-manager in the following way:

with watcher('computation name', email='my@email.com'):
    run_long_computation()

When the computation is finished it prints on screen the number of days or seconds elapsed and sends a notification by email.
A few easy improvements could be made to it:

• allow to use desktop notification instead of email
• add an IPython cell/line magic to do the same

What do you think ? If polished a little bit (no docstring), it could be a nice addition.

This is neat. +1 for adding it to the library once the docstring is included, perhaps in timing.py. Alternatively timing.py can be renamed utils.py as per @spencerlyon2 's suggestion.

Good idea ... +1 for adding it to the library. I have just recently been
thinking of implementing something similar.

@albop I will write and docstring and include this in the new utils subpackage once the RandomMarkov PR has been merged. There is a reorganisation of utilities in that branch and I don't want to cause any merge conflicts.

Basic tic, tac, tok functions are now in utils sub-package. Leaving open for suggested improvements.

@mmcky: where does this one stands ? I just realized that I may have forgotten to make the gist public.

Hey @albop - thanks for the reminder. Do you want to submit a PR or should I just add this to the utils subpackage? We will probably want to have an email parameter for the test function - otherwise you may get a lot of test responses :).

[albop]

Good catch about the email ! That was careless of me...
I honestly don't know if it's ready to merge. This was more a proof of concept and should probably be tested on a few platforms before merging. I don't know whether it works on windows for instance. Desktop notification would be good too, although not mandatory.

Ok - Cool. I will have a look into this feature next week. I really would like this functionality.
