PSGI/Plack: http://plackperl.org/

node.js for HTTP-related activities. (I needed a rate-limiting proxy that returned a special HTTP code when the rate limit was exceeded. 20 lines of node.js later...)

0MQ: the way network messaging should be. (Did you know that the same socket can be bound and connected multiple times? Amazingly flexible.)

beanstalkd I've worked with MongoDB, Cassandra, and a host of other tools, libraries, databases, and frameworks, but beanstalk is the only one to never fail me. It's not a full swiss army knife like Redis or the sexy app of the year like MongoDB: beanstalk does 1 job and does it, as far as I can tell, perfectly.

+1 for beanstalkd. Zero deployment and blazing fast!

Solid State Discs in everything. Ok, perhaps not what you were asking, but they made a big difference for me. I have two, raid0 in my desktop, and a sandforce in my MBP. What a difference. Compiling, linking, copying, everything not just faster, but almost instantaneous. Yum.

Buying an SSD was a huge disappointment for me. Programs were not "almost instantaneous" but just 2-3 times faster to load if there was a difference at all. So OpenOffice took 3 seconds instead of 7, not worth the huge price difference for me. Compiling is CPU bound, I noticed no mentionable difference there. It might be worth it if you use a "bloaty" OS with virus scanners and indexers running or have specific use cases where very fast access is needed, but for a lightweight system the difference is neglible. The only real difference I actually noticed without looking at numbers was that after startx the XFCE desktop was ready before the monitor did its resolution switch. Lots of random reads in that process I guess. From a HDD it takes a couple of seconds (once per day...).

I returned it. And before some is implying I am dumb: Yes, I had a fast and quick SSD and my system was setup to use it well.

The closest to "cool, shiny and new" I got was Scala. And I never found time to dig as deeply into it as I wanted, so I still haven't done any meaningful coding in it yet. But I did sit down last week and spent a couple of days working through the Programming Scala book, and one of my major goals in 2011 is to learn Scala well.

Other than that, the stuff I did this year that was merely "new to me" was mostly about Groovy and Grails. I spent a ton of time working with Grails, and I'm really liking it.

Jekyll ( https://github.com/mojombo/jekyll ) First touched it two months ago just to tinker with but didn't really do anything with it. Then after numerous frustrations with my current blogging setup, I spent the last 5 days hacking on it over the holidays and I think it's almost ready to launch. Had to do some custom stuff that I'll write about in a post. It's extremely hackable and I love it. The only thing that do…

I tried using Hyde, the python port, but I wasn't sure how to get half of it to work, there was so little documentation.

What's some stuff you've printed?

mostly just silly calibration cubes. a few space invaders and companion cubes to give to friends. today i (continued) work on a spindle to hold the big spool of plastic. cnc is so much fun. I think i'm going to have to get a cnc mill. this is just to tempting. http://lcamtuf.coredump.cx/guerrilla_cnc1.shtml In the near term i'll probably just print some brackets and containers for stuff.

I'm trying to think of enough things I would print so I can justify getting one. No luck yet :-(

Sure. You can disrupt someone on the toilet, at the dinner table, in bed, etc, etc. Very disruptive indeed.

There was a time in my life, where every single time my girlfriend and I were about to enjoy some adult time, my employees would call. Without fail. There has to be some sort of twillo app idea in there somewhere.

I'm not sure how Twilio would help me any further with turning my phone to silent when I don't want to take calls.. ;-)

We just need to tap into the accelerometer, do an FFT and low-pass on the microphone, and check for a correlation between the frequency of a rhythmic acceleration and the frequency of grunting.

There is actually a project going on at my university that basically does that. It's an iPhone app that takes the accelerometer and sound input into consideration. They guys doing that app are graphing the data and have an algorithm rating the "performance". It's supposed to be a little criticism about the current state of privacy (and it includes abilities to share your scores in Twitter and Facebook :) )
