It recently occurred to me that a certain website that I check regularly could be given an unofficial RSS feed by writing a script to pull in data from its SOAP interface and spit it out as a feed. Not many websites have SOAP interfaces, but this one does, and while I’m not sure they created it to allow third-party RSS feeds in particular, I’m sure they don’t mind if I just use it for my own secret consumption. That means I won’t be disclosing which site it is that my script is accessing, although the general principle about how to write a script like this should be more useful anyway. Of course I used PHP for the script, because that’s what webhosts support, so if you want a version written in a nice language like Groovy I’m afraid you’ll have to port this script to that language.

Yet again I have found myself on the wrong side of Debian’s strict packaging policy. There is a piece of software that I want to install which isn’t packaged for Debian, but which fortunately is packaged for the sister distro, Ubuntu. This alternative source of packages is only useful, though, if Ubuntu uses sufficiently similar package names and version numbers, otherwise the Debian package management tools will treat the package as invalid due to dependency problems. The last time I had to deal with this sort of problem was with an earlier version of the same package, plasma-widget-adjustableclock, but this time the dependency problem is slightly different and I’ve tried fixing the problem in a different way too. Below I detail what the problem is, and my not-entirely-successful efforts at solving it.

The opportunity to speak with Americans about their federal system is one I rarely turn down, as it helps me understand Europe’s federal system. While talking to a particular American, I found that, despite the stereotypes, they did not believe that the EU was a federal country, and although this meant they agreed with the vast majority of Europeans on the matter, I decided to dismiss their view as uninformed and presented them with a video of the EU president celebrating the EU national day by reading a speech and watching the EU flag being lifted by members of the EU army, followed by a military band performance of the EU national anthem. I feel, though, that to really convince an American (and possibly a European too) that the EU is a country, I must provide a list of the state flowers of each of the EU states, which was, as I explained in an earlier blog post, one of the only things the EU was missing.

I’ve recently made a few changes to my blog and thought that, in the self-referential tradition of bloggers, I should mention some of the decisions I made and how they affect my blog. The most external change, and the one mentioned in the title of this post, is that I do now have a domain to host this blog on. By “external” I don’t just mean it is potentially visible in your address bar when you visit any page of the blog, I also mean that it involved interaction with various third parties. It is a change I had been meaning to make for a while now, and one I should have made long ago, but hopefully it should last a long time.

By a strange coincidence, I’ve recently bumped into another PHP gotcha, well, actually three of them depending on how you’re counting, but I’m sure that these must be the last three unexpected things about PHP and I won’t soon have to write another blog post detailing something else unintuitive that PHP does. The reason these could be seen as one gotcha is that they all involve PHP’s support for floating point numbers, so one workaround would just be to not use that datatype at all in your programs. As I will show though, it is harder than you might think to avoid them, so perhaps the best advice is to avoid using numbers at all. To be on the safe side though, maybe you should just use a different programming language.

Email is an open standard, or several standards, as well as being many other things, such as a means of communication. Something that people might consider from time to time is “Why there is so much unsolicited bulk email?”, although for some people the answer is obvious. Others might not ever ask themselves that question, even if they use email, because they believe the spam problem has been beaten, but it hasn’t, and it is costing email providers and society a lot of money. I have been thinking about this issue myself recently, and on and off for a while, and I have some thoughts about it. While I have neither come up with a means for ending all spam, nor decided that the current email system should be abandoned, I do have a collection of thoughts which help me frame the issue and might help other people in some way.

I haven’t written many blog posts about open standards recently, and that’s possibly because all the old standards are too boring and the new ones are too immature, but I think that OpenID has now matured enough and is seeing enough adoption that it is reasonable to comment on it. It is also receiving a lot of criticism, and, while I don’t like to get caught up in knee-jerk arguments, I do feel that there are some legitimate concerns that people have about this promising standard, which I might be able to address with a coherent defence of it in this blog post. Fortunately the defence I’ve come up with should answer many of the objections to OpenID at the same time, as it puts forward a very different way of looking at the technology, one which may not be obvious to people when they first learn about it. I will first state my idea clearly for the record, then deal with any criticism I can imagine being levelled against it.

People can get in trouble for confusing a continent with a country, but actually neither term is particularly well defined. The continental borders of Europe, for instance, are often debated, and even the idea of Europe being a continent is contested by some. It has come to my attention, though, that I myself have made a mistake regarding the status of Europe, or at least the EU, a concept close to my heart (even if the implementation of the concept can at times fall short). It was six months ago in this very blog that I listed “Ambassadors” as one of the characteristics “that makes the EU different from a country”, but I have since learnt that this is not strictly true. Somehow, the EU has managed to convince its member states that it needed diplomatic relations with at least two (other?) countries. To confuse things slightly, there are also ambassadorial level relations with the similarly structured African Union (although not yet with the Union of South American Nations) as well as with the higher level UN. This has all led me to start thinking about what makes a country, and, perhaps dangerously, whether the Lisbon Treaty turns the EU into one (assuming it isn’t already).
