Thinking About Cassandra

This week on the Technometria podcast, Scott and I interview Jonathan Ellis about the Cassandra Project. Cassandra is an open source distributed database management system used by Facebook, Twitter, and other sites. Cassandra is a distributed database that is designed for extreme scalability. Cassandra is one of the so-called "NOSQL" databases. That's something of a misnomer, because its not specifically SQL that they're lacking--although they are that--but relations. Like Amazon's Dynamo and Google's Bigtable (from which it draws its founding ideas), Cassandra is designed to solve the problems that many modern Web applications have for storing data. That's not

Oracle Buy Sleepycat

Oracle announced that they are buying Sleepycat, the maker of the DbXML database I use in several projects. This is good for Sleepycat, but might mean trouble for MySQL. I blogged about it at Between the Lines.

NumSum and Other MicroApplications

I've been playing with a writable Web application called NumSum, a Web-based spreadsheet. Here's a little test spreadsheet I created. They have a "blog this" feature which creates an iFrame of the spreadsheet. Here's what it looks like: Go ahead and change some cells and it will recalculate. Your changes won't be persistent. This is unlikely to put Office out of business anytime soon, but as a demo application, it shows just how far this might go. Doesn't feel like a Web-app, does it? NumSum was built to show off the capabilities of TrimPath, a "web Model-View-Controller framework that

Google Base Portends a Structured Web

I wrote a piece at Between the Lines today about the newly launched Google Base. Google Base has been described variously as an online database, competition for CraigsList, or Google's first crack at eBay. And of course, Base is being judged in that light: Google Base can be used to store information of any sort--the company seems to like using recipes as an example. Already, there's commercial stuff like classified ads and job listings in there; the service has been described as an eBay killer or a Craigslist killer. At the moment, it's clearly very far from being either.

Learning from the Web

I've heard Adam Bosworth talk about the lessons we should have learned from the web about semi structured data, but it didn't really hit home for me until I read his arguments in this article in Queue. I read it in hardcopy 6 weeks ago or so and it's finally online so I can link to it. He lists five "unintuitive" lessons: Simple, relaxed, sloppily extensible text formats and protocols often work better than complex and efficient binary ones. It is worth making things simple enough that one can harness Moore's law in parallel. This means that a system
