Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

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.
A functor is something that supports map.

| /** | |
| * Fancy ID generator that creates 20-character string identifiers with the following properties: | |
| * | |
| * 1. They're based on timestamp so that they sort *after* any existing ids. | |
| * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs. | |
| * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly). | |
| * 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the | |
| * latter ones will sort after the former ones. We do this by using the previous random bits | |
| * but "incrementing" them by 1 (only in the case of a timestamp collision). | |

| 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) |

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.

Uploading a ton of stuff to S3, I decided I wanted something that would take this boring *os.File and give me a progress indicator. Here's the thing I threw together. Sends this sort of thing to stdout ('\r'ing over itself every second): 10MB/72MB (14.6%)

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.
