My advise on what you need to do to become a data scientist...

If you were to give recommendations to your "little brother/sister" on things that they need to do to become a data scientist, what would those things be?

I think the "Data Science Venn Diagram" (http://drewconway.com/zia/2013/3/26/the-data-science-venn-diagram) is a great place to start. You need three things to be a good data scientist:

  • Statistical knowledge
  • Programming/hacking skills
  • Domain expertise

Statistical knowledge

Advise for teaching an R workshop

I think the two most important messages that people can get from a short course are:

a) the material is important and worthwhile to learn (even if it's challenging), and b) it's possible to learn it!

For those reasons, I usually start by diving as quickly as possible into visualisation. I think it's a bad idea to start by explicitly teaching programming concepts (like data structures), because the pay off isn't obvious. If you start with visualisation, the pay off is really obvious and people are more motivated to push past any initial teething problems. In stat405, I used to start with some very basic templates that got people up and running with scatterplots and histograms - they wouldn't necessary understand the code, but they'd know which bits could be varied for different effects.

Apart from visualisation, I think the two most important topics to cover are tidy data (i.e. http://www.jstatsoft.org/v59/i10/ + tidyr) and data manipulation (dplyr). These are both important for when people go off and apply

Storytelling from Space

Storytelling from Space: Tools/Resources

This list of resources is all about acquring and processing aerial imagery. It's generally broken up in three ways: how to go about this in Photoshop/GIMP, using command-line tools, or in GIS software, depending what's most comfortable to you. Often these tools can be used in conjunction with each other.

How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Pull request feature requests

Hello Github,

Pull requests are not serving me well on large reviews. Here are some problems and suggested enhancements that would make me happy.

  • Mark comment as "resolved" (see google docs for an example). As code changes, comments get lost or made redundant, and it is not clear (to either the author or reviewers) which are still relevant and which have been addressed. Resolving a comment doesn't need to make it dissappear, but I need to be able to see "which comments have not been addressed" somehow. This feature would be the most useful to me.
  • Reply to a comment. This can be done in effect on line comments (assuming there is only one), but cannot on PR comments. Particularly with many threads, the lack of this makes a review hard to follow.
  • Explicit "approve/block" life cycle. The block is actually more important to me ... often on a PR that has been incrementally improved I want to "block" final merge of it until I get a chance to rebase/squash and generally pretty it up. The block can be over
