Linux sort by column

	cat file \|sort -k3nr

	# -n -- sort numerically (not lexicographically)
	# -k3 -- sort by the 3rd column
	# -r -- sort in reverse order (bigger values first)

	This is different to \|sort -nk3r for some reason

Last active December 15, 2016 01:14

Selenium switch tabs

	# Current versions of Selenium are so silly that if an action on the page
	# results in a new tab being opened, the browser will switch to the new tab,
	# but the selenium driver will still think the old tab is visible, so if you
	# try to access elements on the old tab, they will fail with 'element not visible'
	# errors.

	# One way to fix this is to explicitly switch to the new tab and close it
	# (if you have an element that will close the tab).

	driver.switch_to.window(driver.window_handles[1])
