HATEOAS in 3 lines

Stefan Tilkov brilliantly sums up the out-of-band information problem in REST's HATEOAS constraint on the REST-discuss group:

Given the representation contains

<link rel="some-concept" ref="/some-uri">

you don't hardcode the string "/some-uri" into your client, but rather the string "some-concept".

Python script to set genre in iTunes with Last.fm tags

Now that I have started to seriously use iTunes I figured it might be nice to have the genre tag set in a meaningful way. Since I have a reasonably large collection of mp3s doing that manually was out of question - I wrote me a Python script to do that. There seems to be a large demand for such a functionality (at least I found a lot of questions on how to automatically set the genre tag) so maybe someone else finds the script useful. It is pasted below. General Strategy The basic idea is to use Last.fm's tags for genre tagging. In iTunes the genre tag is IMO best used when it only contains one single genre, i.e. something like "Electronica", not something like "Electronica / Dance".

Germany’s most anticipated Web 2.0 sites - one year later

I just came across a post about Germany's most anticipated Web2.0 sites that dates back to last August. Since this is almost exactly one year ago I decided to spend half an hour of my life and conduct a completely unscientific survey to see how many of these startups are still around. For this reason I simply looked at the web sites to see if they are still here and checked if there are recent posts in the company blog to check if the site is a zombie (if there is no blog I checked the press releases). The result is: 51% are still around, 36% are gone (or not started one year later). The rest seems shaky (last blog post 6 months ago) or unknown (state cannot be determined by looking at the blog). If you consider that these startups were above the rest ("highly anticipated") and that checking if there are even online one year later is a very low barrier I was surprised by the low survival ratio. But one can regard this as positive: "quick failure" is a good stra
