Joel and Ruby performance

Joel of Joel on Software fame has bashed Ruby performance on his blog. The outcry caused by this flamebait has been large as expected. Yet, out of the gut (without any benchmarks to back up my feelings) I thought he was probably right that Ruby is small.

However, I found an interesting comment on the Smallthought blog: the author points out that Ruby's performance is slowed down by a naive implementation of the interpreter and points to a Smalltalk interpreter just OSSed by Sun. Now, if we combine this and Sun hiring the JRuny guys there is cause for hope to get a better Ruby interpreter in a short while.

NoSQL talk at Developer Summit

Three days ago I had to chance to talk about NoSQL at the Internet Briefing's Developer Summit. On top of general ideas and concepts like the CAP theorem I chose to talk about Apache Jackrabbit, CouchDB and Cassandra. My slides are embedded below.
It was a really good event with interesting speakers and a knowledgeable audience. I was especially pleased that when I talked about CouchDB's HTTP API someone from the audience mentioned that Apache Sling does something very similar for Jackrabbit.
Special kudos to Christian Stocker of Liip for daring to do a live demo of the "real-time web" - he took a picture from his phone and had it pop up on Jabber and Twitter in about 5 secs.
Vlad Trifa has posted a good summary of the whole event (part 1, part 2) - he also gave a great presentation about the application of the REST architectural style to the "Web of Things".

NoSQL: A long-time relation(ship) comes to an end

(cross-posting from here)

OK, I admit it, declaring that "the RDBMS is dead" is a meme that has been going around the software industry for a while. Remember object-oriented data bases that were supposed to replace the relational ones? Well, guess who is still here. However, despite the RDBMS's amazing survival skills I would like to propose a related prediction:

I believe that the year 2009 will go down in history as the year when the "relational model default" ended. The term "relational model default" was coined by me to describe a peculiar thing that goes on in application development: start talking to your average application developer about some arbitrary business requirement and chances are that simultaneously he mentally constructs a relational model to fit those requirements.
That relational approach to modeling your problem may or may not be suitable. The real problem is that all too often this default does not get challenged. As a consequence,…
