So I flew out to San Francisco last week for the Node Summit conference. I wasn't sure exactly what to expect. The first event was the NodeUp live pod cast at the Bottom of the Hill bar. I was in the Mission immediately prior to that and it was a long walk (after 5.5 hours of walking) to get there. The crowd seemed to be almost all developers and it was surprisingly international. I got to meet some folks I admire from the Internet like....

I got into a conversation at work today about whether or not Node.js might become as popular and as ubiquitous as Ruby on Rails has become, or if it's just a fad. At first I was like "It's going to become the most used framework evar!" But then I thought about it a bit more and realized that this might not be the case.

Problem: Prove or disprove: at a party of $ n$ people, there must be an even number of people who have an odd number of friends at the party. Solution: Let $ P$ be the set of all people, and for any person $ p \in P$, let $ d(p)$ be the number of friends that person has. Let $ f$ be the total number of friendships between pairs of people at the party.

Update: Snakes in a Tower is complete! Downloads with source available for Mac and PC . Friday 4:59pm This is my first Global Game Jam. Super excited. So I'm going to liveblog it.

Saturday 12:20am Opening meeting was awesome. Heard some fantastic keynotes fro..

Update: il Piccolo Libro di MongoDB, Edizione Italiana è ora disponibile online. Ho cominciato a lavorare alla traduzione autorizzata dell’ottimo The Little MongoDB Book di Karl Seguin. Ho scovato il libro di Karl mentre raccoglievo la documentazione per un nuovo progetto super-segreto (!) a cui sto lavorando. Lo ritengo un’ottima introduzione al mondo NoSQL in generale e naturalmente al fantastico MongoDB. Il titolo italiano sarà Il....

I’ve recently been amazed at the number of companies that are still using a VPN or other means to manage their apps/network. Not just large enterprisey companies, but small agile startups. I fully understand that it works, but 95% of these places are also using another key tool for access inside their company… Google Apps . I fully expect companies to use google apps, its more of the former that surprises me most. For a long time OpenID wa....

This post assumes familiarity with some basic concepts in algebraic topology, specifically what a group is and the definition of the fundamental group of a topological space. The fundamental theorem of algebra has quite a few number of proofs (enough to fill a book!). In fact, it seems a new tool in mathematics can prove its worth by being able to prove the fundamental theorem in a different way. This series of proofs of the fundamental the..

With the massive SOPA/PIPA website content blackout on January 18th (including major sites such as Wikipedia), the general public suddenly became far more educated on digital freedom issues. The music and movie industry has amassed a fortune in the last 50 years selling music and movies before the dawn of the Internet. Back then, if you wanted music, you had to buy it on some physical medium such as a cassette tape or CD. Similarly, if ..
