A friend asked me for a few pointers to interesting, mostly recent papers on data warehousing and "big data" database systems, with an eye towards real-world deployments. I figured I'd share the list. It's biased and rather incomplete but maybe of interest to someone. While many are obvious choices (I've omitted several, like MapReduce), I think there are a few underappreciated gems.

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

• One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
• A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

• Unison for file synchronization
• EncFS for folder encryption

Category theory jargon cheat sheet

A primer/refresher on the category theory concepts that most commonly crop up in conversations about Scala or FP. (Because it's embarassing when I forget this stuff!)

I'll be assuming Scalaz imports in code samples, and some of the code may be pseudo-Scala.

Functor

A functor is something that supports map.

The reason why you might get certificate errors in Ruby 2.0 when talking HTTPS is because there isn't a default certificate bundle that OpenSSL (which was used when building Ruby) trusts.

Update: this problem is solved in edge versions of rbenv and RVM.

$ ruby -rnet/https -e "Net::HTTP.get URI('https://github.com')"
net/http.rb:917:in `connect': SSL_connect returned=1 errno=0 state=SSLv3
  read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)

You can work around the issue by installing a certificate bundle that you trust. I trust Mozilla and curl.

Philosophical:
* writing lines of code is one of the least valuable things I can do
* cultivate your impatience
* reject the status quo, unless we can re-derive it from first-principles 
* engineers imprint on the first languages (techniuqes, frameworks or technology) that we find success with (unconsciously seen as caregivers, which we defend w/o always knowing why)
  * we tend to overvalue the familiar/known; we tend to undervalue the unfamiliar/unknown, this interferes with our receptiveness to new ideas and personal growth
* we're 90% composed of bad habits; many of our best habits become bad as time passes; this allows us to filter for the fundamental; the great
* make doing the right thing easier than any other thing, or we will fail to achieve greatness, or break bad habits
* be conscious, be intentional 
* "is this the highest we can aim?" (I prefer this over "is this the best we can do", the former is aspirational, the latter is judgemental)
