A Study In Data Just before midnight on Thanksgiving, there was a murder by gunshot about four blocks from my home. Luckily I was in bed by then, but all of the commotion over the incident got me thinking: is murder disproportionately more common on Thanksgiving? What about Christmas, Valentine’s Day, or Saint Patrick’s Day? Of course, with the right data set these are the kinds of questions one can answer!

You've probably heard the whole "don't make engines, make games" shtick. As I progress I am learning another important lesson: tools are the most important aspect of any project, game or engine. Whether you're rolling a custom engine or shopping around for middleware, tools should be absolutely top priority. Seriously. The question should not be "how many shiny graphics techniques can I incorporate?". It should be "how easy is it to cre..

Nov. 25, 2011 15:32 NZDT B2 Science, Amundsen-Scott South Pole Station The "South Pile" in windstorm For those of you who don’t know, December and January are the centennial anniversaries of Amundsen and Scott’s arrival at the South Pole, respectively. I think a lot of people are writing online about the event, and at any rate, I’m going to miss the celebration here, so I won’t go too much into the preparation and planning that’s ....

Mia moglie è docente nel liceo artistico della nostra città. L’anno scorso era coinvolta in un progetto che vedeva studenti e professori impegnati nella progettazione di un monumento da installare nella sede dell’Autorità Portuale. Il soggetto scelto dal team erano le onde del mare e ben presto si pose il problema di rappresentarle realisticamente. Un insegnate di Matematica suggerì di ricorrere alla teoria dei frattali. Idea brillante ch..

Those of you who follow me on Twitter would have seen my PC building ramblings last night. Being fed up with playing Deus Ex: Human Revolution on my Mac Mini on lowest settings at 20fps I decided that the time has come to follow through with what I’ve been meaning to do for a while: build a gaming PC.

So Linkzie has had a nice series of updates to the underlying software that runs it. It's now pretty much bleeding edge latest and greatest. Ubuntu 11.10 rbenv Ruby 1.9.3-p0 Rails 3.1.3 Unicorn 4.1.1 jQuery 1.7 It was an interesting process. I just went through a pretty challenging upgrade from Ruby 1.8.7 to 1.9.3 at work and it was pretty destabilizing and chaotic. So for this one I went slow and steady, changing one thing at a ti....

Un anno e mezzo dopo si ritrova con una solida esperienza, $19.000 in banca e un lavoro in proprio. Fa bene ogni tanto leggere queste storielle a lieto fine:

Please use affirmative phrases when naming your boolean variables and flags - I find that it makes code much more readable. This is particularly true when naming the configuration settings used to turn features on or off. If the setting is named in the negative then I have to use a double negative to enable it, and everyone learnt in high school that double negatives are a Bad Thing. For example, if I have a feature that sends emails an..

This is a natural follow-up to our first gallery entry on the impossibility of tiling certain chessboards with dominoes. Problem: Suppose we remove two squares from a chessboard which have opposite color. Is it possible to tile the remaining squares with 2-by-1 dominoes? Solution: Notice that if we remove two squares of opposite color, then there is only one way to place dominoes on the remaining squares according to this scheme (one cannot..

OmniAuth is a great little Rack library that standardizes multi-provider authentication for web applications. As OmniAuth says, “it was created to be powerful, flexible, and do as little as possible.” I use it constantly on hacks that mash up multiple API providers. You can now add SoundCloud to the growing list of strategies OmniAuth 1.0 supports.

I remember debating about this with Ellen months ago at her house. I haven’t yet decided what my stance is on gamification, although I’ve definitely been leaning toward the positive. If there’s something that can make things we don’t particularly enjoy doing fun (or even make things that we already enjoy doing even more fun), that’s awesome. This is already happening with apps like EpicWin and Zombies Run (which is in development afte..
