#B-14918 [solr] Logging and/or metrics around searcher warming times

Since overlapping searcher is a know issue causing cluster instability, we should start logging how long cache warming is taking. Ideally there's a logging config that can enable this, less ideally a script that loads polls for stats and loads into graphite.

Actually... I just found this in New Relic. But it's only Averaged (over time) and Agrregated (Over all the hosts), I'm not terribly certain it will help pin point bad behavior, but is good for an overall view. Transaction traces do show some outliers.

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Turn off k400r Tap to Click

Without even installing drivers, the Logitech k400r tap-to-click functionality can be turned off by holding down the "FN" (function) key and the left click button on the trackpad.

When you cancel a Jenkins job

Unfinished draft; do not use until this notice is removed.

We were seeing some unexpected behavior in the processes that Jenkins launches when the Jenkins user clicks "cancel" on their job. Unexpected behaviors like:

apparently stale lockfiles and pidfiles
overlapping processes
jobs apparently ending without performing cleanup tasks
jobs continuing to run after being reported "aborted"

	This script emulates a stand-alone Python based client. It relies on Boto3 to access AWS, but
	requires your Django server to have an API for your user to access Cognito based credentials

	Because of Cognito, the client (this script) will only get temporary AWS credentials associated
	to your user and only your user, and based on whatever you configure your AIM Policy to be.

	Most Cognito examples demonstrate how to use Cognito for Mobile Apps, so this scripts demonstrate
	how to create a stand-alone Python script but operating similarly to these apps.

	# First of all you need to have a clean clone of the source repository so we didn't screw the things up.

	git clone git://server.com/my-repo1.git

	# After that you need to do some preparations on the source repository, nuking all the entries except the folder you need to move. Use the following command

	git filter-branch --subdirectory-filter your_dir -- -- all

	# This will nuke all the other entries and their history, creating a clean git repository that contains only data and history from the directory you need. If you need to move several folders, you have to collect them in a single directory using the git mv command.
