Javascript on Bruno Pedro

Speaking at the first BarcelonaJS meetup

Tue, 22 Jan 2013 17:53:10 +0000

I’ll be speaking at the first BarcelonaJS meetup on January 30th in MOB, [Barcelona](http://maps.google.com/maps?ll=41.3833333333,2.18333333333&spn=0.1,0.1&q=41.3833333333,2.18333333333 (Barcelona)&t=h “Barcelona”).

I’ll be presenting node-fs and talking about my experience trying to fix the common problem of recursive directory creation, failing to get it accepted into the core of node.js, and planned features for node-fs.

Other speakers include Pablo Casado, who will be talking about how to start with node.js, and also Jordi Romero, discussing a hybrid solution that leverages node.js and Rails.

JavaScript filesystem database

Tue, 21 Dec 2010 18:33:00 +0000

I couldn’t resist and, after many conversations with Mário Valente, I challenged myself to build a complete JavaScript filesystem based database from scratch. In short, something like CouchDB but written in JavaScript and using a filesystem approach for document storage.

Some characteristics of this new database system:

fully written in JavaScript: nodeJS is my choice for its architecture and portability;
every document must contain only JSON data;
every document can be manipulated on the filesystem: the idea is to allow someone to edit a document using vim, for instance, without breaking anything. It also lets you easily backup, move or replicate your data without creating a heavy load on the database;
the underlying filesystem can be changed: changing the underlying filesystem offers numerous possibilities, like easy distribution (using OpenAFS, XTREEMFS or others), replication (using finefs or others), and even attaching different backends (using FUSE, for example);
the system must be available through an HTTP REST interface: this makes it very easy to immediately integrate the system into any existing applications. Bonus points if the API is compatible with CouchDB;
queries must be performed using a MapReduce approach: this should make it very easy to perform queries on a large dataset.

So, right now I’m half way through it. I managed to write the backend and I’m on my way to the HTTP REST interface. I’ll create a github repo after I have something functional that can be easily built and tested.

DecentralizedAddresses Chrome extension

Mon, 08 Mar 2010 14:24:36 +0000

After much discussion around the @replies subject I started thinking about a system that could automatically resolve social network addresses no matter where they appear. I then decided to try the approach of writing a Chrome extension that could do the job.

The DecentralizedAddresses extension is in development and is available on github for anyone to contribute. As my JavaScript skills are not very good, any help would be highly appreciated.
