`groupby` and `countby` for python

Python has the standard methods for applying functions over iterables, viz. map, filter, and reduce.

For example, we can use filter to filter some numbers by some criterion:

even = lambda x: x % 2 is 0
odd  = lambda x: not even(x)
data = [1, 2, 3, 4]

On Mac OS (host):

Shutdown your VM and do:

VirtualBox > Settings > Network > Add (you will get vboxnet0)

On a terminal ifconfig will show you new interface vboxnet0

VM's Settings > System > check "Enable I/O APIC." VM's Settings > Network > Adapter 2 > host-only vboxnet0

openssl

Install

Install the OpenSSL on Debian based systems

sudo apt-get install openssl

To use Webster's 1913 dictionary on Android, install Colordict 3, an app that accepts this StarDict format. https://play.google.com/store/apps/details?id=com.socialnmobile.colordict

Next download James's S3 archive. https://s3.amazonaws.com/jsomers/dictionary.zip

You will need to extract the .dict file from inside three containers - .dz, .tar, .bz2 from innermost to outermost. 7zip handles all of these formats.

Place the .dict, .idx and .ifo files in the dictdata directory on your sdcard or local storage root. This is where colordict looks for dictionaries.

When the files are in the right place, you can run Colordict and tap the folder icon in the top right to see the dictionaries installed and set the dictionary priority. I put the 1913 dictionary above the defaults "Wordnet" and "Wikipedia." When you look up a word, ColorDict shows the definition, if available, from these multiple sources.

	Stevey's Google Platforms Rant

	I was at Amazon for about six and a half years, and now I've been at Google for
	that long. One thing that struck me immediately about the two companies -- an
	impression that has been reinforced almost daily -- is that Amazon does
	everything wrong, and Google does everything right. Sure, it's a sweeping
	generalization, but a surprisingly accurate one. It's pretty crazy. There are
	probably a hundred or even two hundred different ways you can compare the two

	#!/bin/bash

	usage()
	{
	cat <<EOF
	Usage: $(basename $0) [options]

	This shell script is a simple wrapper around the openssl binary. It uses
	s_client to get certificate information from remote hosts, or x509 for local
	certificate files. It can parse out some of the openssl output or just dump all
