Ask HN: What are you planning to learn in 2013?

Android development Ruby Better Java

Cooking really is about process, proportion, texture, color (taste), color (presentation), balance, contrast, seemlingly unrelated items coming together creating new experiences.

It will help you understand these terms in music and art more naturally while at the same time being easier to get started with (i.e. you have the skills necessary to create a dish more than to play the piano and draw)

ROFL, I'm scared to even answer this, because my ambitions for "what to learn" every year are always WAY too big to actually accomplish. So, basically, this year's list is the same as last year's[1] (or the year before), just with even more stuff on it.

So, for starters, the leftovers from last year:

Learn Clojure

Learn Scala

Teach myself Calculus, Differential Equations, Linear Algebra, Probability & Statistics

Dive deeper into data mining, machine learning, and AI stuff.

As it turns out, I didn't make anywhere near as much progress on any of that stuff as I'd hoped (some weird shit happened in 2012 though, so I'm not beating myself up too much).

In addition, I want to learn more about:

1. marketing / positioning / branding stuff. I'm a techie by trade (if not by nature), working on a startup and we don't have a dedicated "marketing guy" so I need to learn enough to get us off the ground at least. Luckily I actually find this stuff interesting, and I did a lot of studying on marketing stuff in 2012 (Chet Holmes FTW)

2. Sales. See above. We don't have a sales guy, so I need enough sales knowledge to at least get that first push going.

3. Influence / persuasion. Always good stuff to have in the repertoire.

4. More and more diving into "big data" / "data science" stuff.

5. More on NLP, "text mining" and information retrieval.

6. In addition to the aforementioned Scala and Clojure, I have a goal of learning some R and Prolog as well. Haskell would be nice as well.

7. Lockpicking. I learned the basics last year, but I need to practice more. I want to get a lot better.

8. Electronics / hardware hacking. I got into the Arduino scene a while back and started doing more low level electronics stuff in conjunction with that, and I'd like to continue down that path.

9. Physical fabrication stuff. I planned to start on a Mantis PCB mill this year, but never got to it. So that, and a 3D printer. A friend has a partially finished Reprap that he wants to hand off to someone else, so I may pick that up from him and start working on that.

1. More and more javascript 2. More CS concepts 3. Music if I got time 4. master my spanish

Another list with Japanese language skill as a goal, love it. Highly recommend traveling there, it's wonderful and confounding at the same time.
