Scientists Tell Us How Your Old Pics Will Change Time-lapse Photography
Fascinating project. A group of researchers at Google and the University of Washington mined 86 million photos from the Internet and automatically pieced them together to create time-lapse sequences of popular places. The video is just 5 minutes and very worthwhile.
Scrape Website Data With The New R Package rvest
Great tutorial by Zev Ross for extracting data from website tables and lists using the R package, rvest. This is well-written with code snippets to make it easy to follow. Along with demonstrating rvest, the tutorial includes steps to geocode and map the extracted demo data.
Top 10 Data Mining Algorithms in Plain English
This is a great introduction to popular data mining algorithms. Each section includes a description of the algorithm, related terms, common use cases, and linked references. If you're not already a data mining pro, this article is Highly Recommended.
The Unreasonable Effectiveness of Recurrent Neural Networks
Here's the latest gem by Andrej Karpathy. This is a clearly presented deep dive into recurrent neural networks with a GitHub repo of code to go along with the article. There's also a worthwhile discussion about the article on Hacker News. Highly Recommended.

A Crash Course in Python for Scientists
If you're just getting into Python, this is a nice place to start. Rick Muller of Sandia National Laboratories created this tutorial to help colleagues come up to speed quickly. It starts with the basics and quickly gets into Numpy, Scipy, Matplotlib, and code optimization. It's presented as an IPython notebook and includes lots of code snippets and references.
Deep Learning - An MIT Press Book in Preparation
MIT Press' Deep Learning textbook is currently in development and is worth paying attention to. Part I, which includes applied math and machine learning basics, is now complete. Large sections of parts II and III are also available and cover practical deep networks and deep learning research.

Windyty
This is an inspiration on many levels. In 2012, Fernanda Viégas and Martin Wattenberg created their well-known Wind Map using data from the National Digital Forecast Database. Wind Map inspired Cameron Beccario to create his Earth project, which includes global data and a variety of additional options. Cameron open-sourced his project and Ivo Lukačovič used that as the foundation for Windyty. Prepare to be amazed.
