Tahoe LAFS

Tahoe LAFS is a distributed file system with an interesting permissions model. (whitepaper) Both Immutable and Mutable files are supported (Mutable is the most complex and interesting) There are three levels of permissions, Write, Read, and Verify. Each permission is granted by giving a user a special key called a "capability". If you have the Write capability you can update the file, if you have the Read capability you can retrieve the plain text, but if you only have the Verify capability you can only validate the file integrity, but not read the contents.

The lower level capabilities are generated deterministically from the higher level capabilites.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

Work in progress, I'll write this up properly when I'm done.

Almost all credit goes to @maxogden for putting me on to this and pointing me in the right direction for each of these items.

Prerequisites:

Raspberry Pi
Kindle Paperwhite freed from its locked down state (jailbroken) http://www.mobileread.com/forums/showthread.php?t=198446
- You have to downgrade your Kindle to 5.3.1 to install the current jailbreak; that's just a matter of getting the old version image, putting it on your Kindle via USB and telling it to install "upgrade". Then you put in the Jailbreak files, load the ebook and break.
Your kindle will be quick to detect an upgrade is available so it'll want to upgrade soon afterwards but the jailbreak will last but you have to reinstall the developer certificates so it's a bit of a pain but doable. Find all the instructions on the mobileread.com forums and wiki.

Gittr.rb

Git as a key-value store! Build with Grit, it supports SET, GET, KEYS, and DELETE operations. In addition, we can also get the change history of key/values.

And since it's Git, we can easily enhance it to include other awesome Git features such as branches, diffs, reverting, and more!

Example:

	import os
	import numpy
	from pandas import DataFrame
	from sklearn.feature_extraction.text import CountVectorizer
	from sklearn.naive_bayes import MultinomialNB
	from sklearn.pipeline import Pipeline
	from sklearn.cross_validation import KFold
	from sklearn.metrics import confusion_matrix, f1_score

	NEWLINE = '\n'
