EX: http://www.drbunsen.org/coffee-experiments/ Based on this analysis, subjects did not show a statistically significant preference in coffee brewed from a blade grinder or burr grinder.
First off only ~1/3 of coffee drinkers take it black which masks a lot of taste variation.
Second, taste sensitivity varies widely. https://en.wikipedia.org/wiki/Supertaster
Put together well under half of coffee drinkers notice subtle differences in grinding methods. Assuming the devices are setup to similar grinding levels and use similar source beans.
Note: You can find examples on both sides of this issue. But, the blind taste tests that repeat over time fail to provide the expected consistency.
PS: There are a few people that both notice and care about these issues, but they really are the minority of coffee drinkers.

Thanks for sharing. There are a lot of cool ideas here. I've had the most sucess with a custom notebook approach using QR codes to stitch together analog and digital information:

And Seth Brown wrote a few useful small functions too.

There have been some posts on Hacker News describing this philosophy (see below, can't find the HN comment links unfortunately).
Another advantage is that it encourages separating your policy from mechanism. For example, you can make your sampling rate or number of buckets a command line flag, and have all your parameters in the shell scripts, rather than having various constants strewn about the code.
And obviously you can use each language where it's stronger. Python is better (and much faster) for the data cleaning part, whereas you might want to use ggplot in R.

Clever, but Powerline-themed context around your current shell environment seems more suited to implementation in something like tmux - see https://github.com/erikw/tmux-powerline or http://www.drbunsen.org/text-triumvirate.html

This was a good list for the intermediate command line user looking to customize. For the absolute newbie I'd reduce it down to git/hg, ssh, grep/ack and curl.
For crazy power users, I'm a huge fan of vim+tmux+zsh combo as described in http://www.drbunsen.org/text-triumvirate.html

I guess that makes sense. Been trying to revamp my coding environment, and decided to go with drbunsen's text triumvirate.
http://www.drbunsen.org/text-triumvirate.html
For now since I'm just working on a RoR app as a personal project, I don't really have a server and tmux's capabilities are limited on my end. So I might give tmux a go first and familiarise with it first, so i'd be more up to speed when it's capabilities can come to play fully :D
Thanks (:
