Not that I am a fan of rewriting stuff, but there are some applications that I use to showcase technologies and from time to time I set up to rewrite them. As there is already a specification, its a matter of an exercise for new technologies. No over-specification and a very delimited time box.
Lately, two of these apps are a pastie clone and an url shortener. First I wrote them in ruby, them in python, python with twisted and now using Erlang and Mochiweb.
Both of them use Redis as a global increment and cache server, along with MongoDB for storing documents and stats. I find this to be a good match due to Redis atomic operations and pub/sub capabilities.

Last saturday I presented an updated version of what sent me the noSQL way at nosqlbr – the first noSQL conference in Brazil. Basically I talked about stuff I did and I saw when I gave consulting to legacy systems. Life is not pretty but there are ways out.
The event was great and I sent a recap to myNoSQL . I got really surprised that so many people got interested on noSQL and alternative/emergent technologies.

I’ve wanted to prototype an URL shortener some time ago to have a measure on how long it would take to do using a NoSQL DB to store stats and do analytics. The main reason would do it using cyclone and MongoDB, and later build over it to create a tracker, web analytics tool and maybe a NGINX module.

Seems like DSLs for web development are getting more solid in the python camp (alto I’m yet to see something like sinatra out of the box or something that spare me from too much CSS’ing).
Today I read about Bottle and Redis, and to keep things fresh, cooked up a PasteBin clone using Bottle and MongoDB. I may do it using Redis too, just to showcase the differences. It’s really easy to come up with prototypes using Bottle.

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.
The first example is a basic comet server which prints a string to each connected user
The other example sends the result of twitter searchs to all connected users:
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).

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