Through the magic of technology, Julian now has a song available for sale on iTunes.  Pretty cool to see.  You can search for it in the iTunes store or go here to see the Julian Hornik iTunes page.  Fun.

  The streets were pretty quiet, which was nice. They're always quiet here
  at that time: you have to be wearing a black jacket to be out on the
  streets between seven and nine in the evening, and not many people in the
  area have black jackets. It's just one of those things. I currently live
  in Colour Neighbourhood, which is for people who are heavily into colour.
  All the streets and buildings are set for instant colourmatch: as you
  walk down the road they change hue to offset whatever you're wearing.
  When the streets are busy it's kind of intense, and anyone prone to
  epileptic seizures isn't allowed to live in the Neighbourhood, however
  much they're into colour.

OOPSLA 2009 happened a few weeks ago. OOPSLA stands for Object-Oriented Programming, Systems, Languages & Applications and I've always been quite interested in the conference. The proceedings of the conference aren't put online, but I've managed to find two interesting papers:

A Market-Based Approach to Software Evolution (PDF) tries to imagine an open market which is targetted around fixing bugs and improving software. It's quite interesting as it's quite similar to a proposal from Nicholas on spending other people's money. The authors point out many potential flaws.

The Commenting Practice of Open Source (PDF) analyses projects on Ohloh and tries to spot commenting trends. "We find that comment density is independent of team and project size", but they find that it varies from language to language. "Java has the highest mean of comment lines per source lines at.. one comment line for three source code lines" and "Perl has the lowest mean with.. one comment line for nine source code lines". They list as future work to find out why this might be the case.

A few weeks ago I was up in the hills about Geneva reminiscing with my sister about all the things we used to enjoy when we were smaller. When I was younger I used to really enjoy programming computer games, first on my 48K Spectrum and then later on in STOS BASIC and then 68000 assembly language on my Atari ST.

I haven't programmed a game in a very long time. However, I'm an avid gamer, playing games while travelling on my DS and at home on my Xbox 360. I almost enjoy reading Edge magazine more than I like playing games.

At YAPC::Europe in Lisbon, Domm pointed out that the Perl SDL project (which wraps the Simple DirectMedia Layer) was languishing and that we should all programs games in Perl.

A few months later I got around to playing with SDL and made a simple breakout clone which I styled after Batty on the Spectrum, but with gravity. It was fairly easy to program, but there was a lot to grasp. The Perl libraries are a mix between a Perl interface to SDL and a Perlish interface to SDL, with limited documentation, tests and examples.

Of course this is where I join the #sdl IRC channel on irc.perl.org and start discussing with the other hackers (kthakore, garu, nothingmuch). We decide on a major redesign to split the project into two sections: the main code will just wrap SDL and then there will be another layer which makes it easier to use. I've started writing a bunch of XS on the redesign branch of the repository while trying to keep Bouncy (my game) still working. There is a bunch of work still to do but we've made a good start. This is what Bouncy looks like at the moment:

Craig was the founder of VLG (where they always had a bowl of jelly beans at the front desk).

Two people are talking. A man in his fifties and a woman in her mid thirties. Both are understated in appearance, but obviously expensively dressed. Both of their smartphones are turned screen-down on the table. It's unclear to us who is the most important. And it's unclear which one is saying the following]

Governments and corporates know me as 'Switchboard', which is how I like to keep it.

I have an aptitude.

Well, a few aptitudes.

But, mainly - I'm very good at people.

Especially those who can't really be described as people anymore. I know what they're good for, what they want and - how to get hold of them.

I've never saved the world, but I've probably had lunch with someone who has.

I'm who you call if you have, y'know -  a *really* big problem.

I love Dr. Horrible.  I hope they make more Dr. Horrible soon.

I'm trying to update various URLs in the Perl source code. Regarding the Perl/iX for HP e3000 MPE README.

It's very out of date now and most of the URLs are broken. I've contacted Mark Bixby, but he no longer has any involvement with the MPE/iX OS or that particular Perl port.

Does anyone run Perl on this platform? Does anyone build Perl on this platform? If so, please contact me and we'll try and update the details. Cheers!

Moving between countries with various different exchange rates is a bit like the popular concept of "speed blindness". Here's one definition: "The eyes quickly get used to the speed driven and shortly after it seems like we're not moving quite as fast as we initially did, even though we're travelling at the very same speed." (This is not, by the way, the same as the technical definition of speed blindness, which has more to do with angle of vision than perception of distance traveled over time.)

When I moved to South Africa, I found I was suddenly very, very stingy. 100 Rand felt like a lot of money, even though it was really only USD 13. Gradually my mental scale adjusted until 100 Rand was 'cheap', 300 rand was "moderately expensive", and 700 Rand was "on the spendy side". But then, I had to catch myself when I visited the US, because I started thinking of USD 1000 as "a little spendy" instead of "pretty expensive".

Moving to the UK is a similar adjustment. I keep having this subconscious reaction of "everything is so cheap!", even though I'm conciously aware that between exchange rates and currency exchange fees on my US credit cards (it takes time to set up local accounts) each pound I spend is about 2 dollars.

Currency Blindness: The mind develops a sense of "value" and proportion around the numeric representations of a particular currency, which are off balance when moving to a currency with a higher or lower exchange rate.

What we really need, instead of relative currencies, is some universal unit of "value" as the basic comparison for all currencies. Gold is really too large a scale for average users. Potatos might be a better choice (readily available in large parts of the world). We could start talking about the "potato standard" and "potato-based currencies". It would at least be more entertaining. :)

I just finished reading Karl Schroeder's "Lady of Mazes" (great book, read it if you get the chance). It inspires a very familiar feeling.

In the early '90s I was living in Africa, so I missed the first years of the internet as a popular communication medium (I did use BBS's for elementary school research papers, but that was different). But, I was a computer geek, so I was subscribed to computer magazines and read about it that way, and exchanged letters (yes, written by hand with ink on paper!) with friends back in the US who were exploring the new technology. I had a sense of what it was, almost like a blind person from a blind society hearing about vision for the first time, and it was so real to me I could almost taste it. I didn't feel so much like I wanted something, more like I'd lost something and wanted it back. When I did get my first dial-up account a few years later, it felt as natural as breathing, and instantly became a seamless part of my existance.

That's the feeling I get reading "Lady of Mazes". If I could step into that world, where it's not just technologies or communities that we build together, but our entire perception of reality, I would do it in a heartbeat. I would stay in a Japanese pod-hotel, and tune my perceptions to a luxury suite. I'd paint Mt. Kilimanjaro outside my bedroom window, and a Pacific ocean beach on my back porch. I'd spin off a subprocess of myself for tiresome social exchanges. I'd appreciate the beauty of illusion as a work of art. Not as an escapist substitute for reality, but as a lens on reality bringing certain features into sharper focus, with the freedom to change that focus at will. And, apologies to Second Life enthusiasts, but that just isn't it. That's about as close to what I'm talking about as a BBS was to the internet.
