This is a list inspired by some of our current or potential lines of work at the World Bank Innovation Labs. The “Innovations in Big Data Analytics” program helps to strengthen the World Bank capabilities to effectively use big data in its operational and strategic work.

We are always looking for great Data Scientists. If you can solve any of these [using open software], you'll be heads down helping us from day one. Email us to brunosanchez@worldbank.org

1. Nightlights from Satellite

We are building an open stack to process nightly data from satellite and query light output from all known villages. Currently we are doing 20 years of nightly data for 600,000 villages in India.

I got Torch + CUDA working on a Ubuntu 14.04 g2.2xlarge EC2 instance using these instructions. Get the latest CUDA install package by consulting https://developer.nvidia.com/cuda-downloads#linux and grabbing the most recent. (7.0 at time of writing).

I also made a public AMI with this, plus Dan Hon's char-rnn fork pre-installed.

It's ami-9bcadbab, or dreaming-prose-public, in the us-west-2 (Oregon) region. You should be able to copy it to another region if you need to. You can launch an instance in the EC2 console at this URL: https://us-west-2.console.aws.amazon.com/ec2/v2/home?region=us-west-2#LaunchInstanceWizard:ami=ami-9bcadbab

You'll need a g2.2xlarge or g2.8xlarge instance or there'll be no CUDA for you...

OS X's "Word of the Day" screensaver is a great way to passively learn words:

But I've always thought that its word list kind of stunk—it was full of obscure words that I could never really see myself using. I'd prefer something like Norman Schur's 1000 Most Important Words. What if you could plug your own word list into the screensaver?

On a rather obscure comment thread, someone explained where you might find the word list that Apple uses to power the screensaver. It is at /System/Library/Graphics/Quartz\ Composer\ Plug-Ins/WOTD.plugin/Contents/Resources/NOAD_wotd_list.txt. The file looks like this:

Snippets: Build a flat json file for handlebars.js template or jquery-vertical-timelines

UPDATED I've made some updates to the handlebars-json.py script.

• Script now accepts a "usage" argument for "handlebars" or "timeline" or "array"
• Script assumes a header row and strips underscores and spaces and converts header fields to lowercase when creating keys.
• Because the resulting JSON file can also be used to power Vertical Timelines, I've re-named the script to csv-to-json.py.
• The handlebars-json-csvkit.py script remains unchanged. I will attempt to re-work it to create handlebars or timeline JSON in the coming weeks.

See more in the Usage section below.

Setting Up Clojure on OS X

I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.

I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.

This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.

Step 1: Getting Clojure (1.3)
