One of my automated process starts dynos when he feels he need more juice in the pipes. But, while running tests, something failed and just kept 10 or more dynos running. It's a pain to stop those manually.

Here's a simple command line that can be executed to stop all running dynos except those initiated at runtime or in via the Procfile.

heroku ps -a <HEROKU_APP> | grep -o -P '(run\.[0-9]+)' | while read line ; do heroku ps:stop $line -a <HEROKU_APP> ; done

On a recent project, I ran into an issue with Python Selenium webdriver. There's no easy way to open a new tab, grab whatever you need and return to original window opener.

Here's a couple people who ran into the same complication:

• http://stackoverflow.com/questions/17547473/how-to-open-a-new-tab-using-selenium-webdriver
• http://stackoverflow.com/questions/6421988/webdriver-open-new-tab/9122450#9122450
• https://groups.google.com/forum/#!topic/selenium-users/kah4iEPRopc
• ... and many many more.

So, after many minutes (read about an hour) of searching, I decided to do find a quick solution to this problem.

"""Benchmark multiple method of removing duplicates in a list 
    while keeping item's order in the list.

    numpy.unique will likely be faster and more efficient
    the more the list grows.
    If a list is submitted to numpy.unique, it will be transformed and flattened
    into a numpy.Array which it's data structure is more efficient than standard
    lists since all elements have the same size in memory therefor requires less
    access to the memory. Lists are stored as array of adresses pointing to 
    to the objects and requires more memory access (but more flexible).
