I have recently had reason to convert an Access MDB file to CSV for use in a mysql database. I don't like the idea of an Access database on a production server and Microsoft has been agreeing since 1999. As it turns out it is actually very easy, there is GPL software available for the job at http://mdbtools.sourceforge.net/. If you are using Ubuntu or Debian you can use apt-get install the mdbtools package - Nathan Freitas

So any themer or anybody that has created a morph please share your creations for the benefit of others. - Nathan Freitas

Bitcoin is a peer-to-peer network based anonymous digital currency. Peer-to-peer (P2P) means that there is no central authority to issue new money or keep track of transactions. Instead, these tasks are managed collectively by the nodes of the network. Anonymity means that the real world identity of the parties of a transaction can be kept hidden from the public or even from the parties themselves. - Nathan Freitas

If you are interested in Spring 3 on the GAE, there is a newer post about just this topic (and some REST!). The previous post describes the main steps, this post just extends two classes and adds a “sync function”, which allows for syncronizing with data im a Google Spreadsheet. - Nathan Freitas

The Apache Cassandra Project develops a highly scalable second-generation distributed database, bringing together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model. Cassandra was open sourced by Facebook in 2008, where it was designed by one of the authors of Dynamo. In a lot of ways you can think of Cassandra as Dynamo 2.0. Cassandra is in production use at Rackspace, Digg, and a number of other companies, but is still under heavy development. - Nathan Freitas

Just a few days ago, Google announced the release of the Chrome OS source code. Within less than 24 hours, the web was littered with disk images for running the new OS on virtual machines such as VMWare and VirtualBox. I even managed to put together my own Google Chrome OS download in the form of a complete VirtualBox appliance. I’m pleased to announce that I’ve taken it a step further, and now you can easily try it on your own computer from a USB thumb driv - Nathan Freitas
