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 now in Django). Continue reading
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!).
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.
Last night, Robert Nyman hosted yet another successful Geekmeet in Stockholm. I got one of the lightning talk slots and decided to skip my planned presentation and instead show some of my experiments with slit-scan photography. The presentation slides (in swedish) are available (8 Mb PDF) here. Continue reading
We went to Goult in Provence on vacation in August and had a great time. While there, we met Bertil Hansson, artist and photographer. We got talking about digital cameras and how they take excellent pictures that can be viewed immediately. I have been sort of bored with taking pictures lately, but Bertil lent me his Holga for a week and I had a really great time with it! Continue reading
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).
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.
Dear Microsoft, when updating to Office 2008 SP1 for Mac I am asked to download a 180 Mb update file. While I appreciate you continuous improvement of software through the release of service packs, I must object to the poor implementation of the automatic update handler. Continue reading
I have been trying to reduce distractions in my computing environment lately. Apparently, our brains aren’t wired properly for task switching: Continue reading
…soviet dissident Yuri Orlov is sentenced to 7 years hard labor for distributing counterrevolutionary material. Also, some distant, mostly unknown relatives of mine decided to go on the trans-siberian railway. I found the photo album while helping my mom move some stuff in her old basement. Most of the pictures were too blurry but some turned out OK. Continue reading
