Node.js and COMET

Today I started to study node.js, for these last days there was a lot of interesting posts about it.

So to begin understanding it, I setup to port two COMET based examples I did back when I started using twisted to do it.

Note that this may contain javascript misconceptions, as I’m not experienced with it and my js idiom is more geared towards python than proper js.

The first example is a basic comet server which prints a string to each connected user

simple comet

The other example sends the result of twitter searchs to all connected users:

twitter and comet

Node.JS presents a different toolset to solve the current problems we have. It used the excellent libev, among V8 and other cool stuff, and JS is a very modern and flexible language (at least more than I thought about it when trying to do web stuff).

Notes about Redis

I’ve come up with some notes about Redis, RestMQ and mongodb. Uploaded them to slideshare.

NoSQL brief (gentle) intro and some SQL anti patterns

Yesterday I’ve presented this at Locaweb/Brazil as part of our NoSQL cycle. Many other people presented interesting new ideas and I’ve opted for this intro and a piece about Redis which I may publish soon.

Treasure the past

Just a quick one: I’ve found code from my old repository, more than 10 years old. Uploaded it along with VideoDog to my github repository: http://github.com/gleicon/archive . Gotta love old stuff.
