### MATPLOTLIBRC FORMAT
# This is a sample matplotlib configuration file - you can find a copy
# of it on your system in
# site-packages/matplotlib/mpl-data/matplotlibrc. If you edit it
# there, please note that it will be overridden in your next install.
# If you want to keep a permanent local copy that will not be
# over-written, place it in HOME/.matplotlib/matplotlibrc (unix/linux
# like systems) and C:\Documents and Settings\yourname\.matplotlib
# (win32 systems).

Using ruby in place of grep/awk/sed like perl

With options -e, -n, -p, perl can do what grep/awk/sed can, what about ruby?

Let's take the result of ls -l as input and process it with ruby

grep with ruby

\ls -l | ruby -ne 'print if /^d/'

awk with ruby

\ls -l | ruby -ne 'puts split(/\s+/).last if /^d/'

River (getriver.com): Keep a programming journal.

One of my favorite past times is to look at the notebooks of famous scientists. Da Vinci's notebook is well known, but there plenty others. Worshipping Da Vinci like no other, I bought a Think/Create/Record journal, used it mostly to keep jot down random thoughts and take notes. This was great in the beginning, but the conformity of lines drove me nuts. Only moleskines made blank notebooks, so I had to buy one.

At the same time I started a freelance project. The project itself is irrelevant, but suffice to say it was very complex and spanned several months. It seemed like a perfect opportunity to use the moleskine. Looking back, all my entries fell under few categories:

  • Todo
  • Question
  • Thought
  • Bug
  • Feature

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)

26 time management hacks I wish I'd known at 20

  1. There's always time. Time is priorities
  2. Days always fill up | "Only plan for 4-5 hours of real work per day."
  3. Work more when you're in the zone. Relax when you're not. | "It's normal to have days where you just can't work and days where you'll work 12 hours straight"
  4. Respect your time and make it respected | "Your time is $1000/hour, and you need to act accordingly"
  5. Stop multi-tasking. It merely kills your focus.
  6. Set up a work routine and stick to it. Your body will adapt
  7. We're always more focused and productive with limited time.
  8. Work is the best way to get working. Start with short tasks to get the ball rolling.
