Remixing Youtube

An interesting approach to chains of copyright but these are really interesting. None of the participants were involved in making these songs. At the same time all of them were. A guess is that remixes like these will become more and more popular. Where can I buy these songs? Who will get paid? More information at http://thru-you.com/ Read more…

Solving Project Euler Problems With Ioke

For those of you that have been following Ola Bini’s work on Ioke, the dynamic language for the JVM, I am happy to report that the current release 0.1.1 is usable enough to solve Project Euler problems with. I wanted to learn more about Ioke and the best way to learn a new language is to use it on your own. So, here is some example Ioke code for some of the simpler Project Euler problems. Read more…

Integrating Yahoo Search in a Django site in 5 easy steps

I have been experimenting with various search options for the eutveckling.se site for a while. Google Custom Search is nice and very fast, but the number of ads appearing in the search result page makes it difficult for users to separate result items from ads. (Update: I am sticking with Google Custom Search until I figure out how to get Yahoo search to present proper excerpts). Read more…

Twitter synchronicity

Everyone is celebrating this friday in a different way, apparently:

Tweets from different people about how they spend their friday. Schyffel is celebrating buy nothing day, Johan lind is ordering books and Isac is hung over.

What Sun Should Do

Tim Bray has an interesting post titled What Sun Should Do where he lists some suggestions. I have been thinking about Sun for a while and how my own image of the company has changed over the years. A long time ago I was working for Cambridge Technology Partners (later acquired by Novell). We did a lot of interesting projects, some of which were deployed on Sun hardware. At that time (around ’97-’98) my image of Sun was that it was a huge company selling huge hardware at huge prices. Read more…

Improving Django performance with better caching

The Django cache middleware is great, but has one drawback. If you are caching views (which can give a nice performance boost) Django will only use the path segment of the URL to create a cache key. If you are an avid reader of RFC 3986 you may remember that a URI consists of multiple components; path and query being of special interest here. The problem is documented in ticket 4992 (Update: it is not in Django). Read more…

November 3: Twitter friend icon impersonation week begins

For a long time I have been amazed how much expression you can get into the twitter icon. It is only 48 by 48 pixels but many of my contacts manage to squeeze a lot of style in there. So, starting on monday november 3 I will change my twitter icon once every day trying to impersonate people who follow me on twitter. At the end of the week I’ll publish all icons side by side for your viewing pleasure. Anyone else up for the challenge?

(note: if everyone in my feed does this there might be a slim possibility to see all my followers looking like me. Apart from me, who will look like someone else. Ah, the excitement!).

Serialization formats don’t matter

I mean, if working with RDF has taught me one thing, it’s that converting between two different forms of serialization is trivial—it’s the underlying model that matters.

Exactly! And still, many who are in the integration business think that XML schemas is the only product required to exchange data between multiple parties. The serialization format(s) should be based on the use cases of the information. And even in a small organization use cases tend to pop up all the time demanding new formats. Most SOA-people see a problem with multiple serialization formats but I am thinking that it is almost insignificant these days if you have a well defined model.

Hello OpenGL World in Ocaml

I swear, if I read one more programming tutorial that starts with a recursive factorial function instead of a simple “Hello world” I’ll pray for perpetual nigerian spam on their inboxes. So, I was delighted to try out some Ocaml stuff today that didn’t involve factorials. Read more…

The broken state of EU legal information on the web

In my pet project eurlex.nu I find a lot of weird stuff when scraping documents from the official website eur-lex.europa.eu. The most recent specimen – Final adoption of amending budget No 4 of the European Union for the financial year 2008 – has the publish date 80/80/2200. That’s almost two hundred years into the future with an invalid day/month combo on top. This leads me to believe that the system is in such a broken state that even simple date validation isn’t implemented.

Someone delivered a really poor software project for our tax money. I would love to redo the european legal information website with proper standards (e.g. validating HTML, RDF and proper semantics).

Oh well…

ODF approved as Swedish Standard

Without making a press release or public announcement the Swedish Standards Institute has formally approved ODF 1.0 as a national standard. Only the “SS” prefix in SS-ISO/IEC 26300:2008 give away the status of the document.
