Builds node on ARM chromebook. Slower than cross compiling, but what the hey!

	git clone -b v0.10.20-release https://github.com/joyent/node.git

	cd node

	./configure --prefix=/ --without-snapshot

	export BIN_NAME=node-v0.10.20-linux-armv7l-chromebook

CDH4 MRv1 install in pseudo-distributed mode, plus optional ZooKeeper, HBase, HttpFS. Assumes you have a Sun JDK installed and JAVA_HOME set for root if installed somewhere other than /usr/java/. This is all basically a summary of various parts of https://ccp.cloudera.com/display/CDH4DOC/CDH4+Documentation

	# Add Cloudera RPM-GPG-KEY and repo
	rpm --import http://archive.cloudera.com/cdh4/redhat/6/x86_64/cdh/RPM-GPG-KEY-cloudera
	rpm -ivh http://archive.cloudera.com/cdh4/one-click-install/redhat/6/x86_64/cloudera-cdh-4-0.x86_64.rpm

	# note: if you want to install a specific version,
	# modify /etc/yum.repos.d/cloudera-cdh4.repo accordingly.
	# For example, if you want to install 4.2.1, use the following baseurl:
	# baseurl=http://archive.cloudera.com/cdh4/redhat/6/x86_64/cdh/4.2.1/

	# Install CDH4 Base

ipxe boot script - despite several of these parameters being in the preseed.cfg file, they don't work unless you pass them in as kernel params. Not sure if that is a documentation bug or an actual bug.

sturadnidge / 75-persistent-net-generator.rules

Created June 2, 2013 22:53

Debian Wheezy 75-persistent-net-generator.rules - for some reason it was missing from the last Raspbian build I did.

	# These rules generate rules to keep network interface names unchanged
	# across reboots and write them to /etc/udev/rules.d/70-persistent-net.rules.

	# variables used to communicate:
	# MATCHADDR MAC address used for the match
	# MATCHID bus_id used for the match
	# MATCHDRV driver name used for the match
	# MATCHIFTYPE interface type match
	# COMMENT comment to add to the generated rule
	# INTERFACE_NAME requested name supplied by external tool

M101P week 2 solution in node.js

	'use strict';
	/*
	* Homework assignment 2.2 for M101P, using node.js
	*
	* Notes: this only works because the student id
	* increments by 1, and also because each student
	* has more than 1 homework score. If either of
	* those conditions weren't true, this code would
	* be totally wrong (and dangerous!).
