Whenever I listen to old fashioned media business types, I find phrases like “Shutting the stable door after the horse has bolted”, “How are we going to keep ’em down on the farm now they’ve seen Paree?” and “Pissing against the wind” running through my head. The basic assumptions on which media companies are built - Talent is hard to find; distribution is hard - have become self-evident bollocks. Media have changed.

Several years ago, Mark Jason Dominus gave a lightning talk entitled ‘Design Patterns’ Aren’t. I didn’t see the talk, but I did come across his writeup not long after I first discovered the Gang of Four’s Design Patterns book. In that talk, Mark put his finger on an issue that had almost subliminally bothered me: many (possibly all) the patterns in that book weren’t really patterns. At least, not in the way Christopher Alexander - the architect who invented the form - described them.

Okay, so I know GUI coding’s a pain in the bum. I know that the windows libraries aren’t the most friendly. I know it’s not fair to point and laugh. But… -> IronPython Hello World Tutorial Bwah hah ha ha. Of course, I don’t doubt that huge amounts of the boilerplate hoopage in the code shown can, and will, be abstracted away. But right now it’s just painful. IronPython’s one hell of an achievement though.

In my semi regular trawl of the searches that bring people here, I was surprised to discover that someone had arrived searching for piers cawley nottingham university. What do you know, they probably found the right person. If you’re thinking that I’m more than a little curious about who has been searching for me, you’d be right.

I’ve been busy with a new experimental branch of typo that plays well with edge rails, in part because I wanted to move to a more RESTful URL scheme for Typo. But then I took a look at some of the things going on in Rails Core and my nipples exploded with delight. For instance, there’s now a ResourceFeeder helper that pretty much magically deals with Atom and RSS feeds for Rails Resources, which would allow us to eliminate a whole pile of ugliness in the Typo source.

There was a session at EuroOSCON on ‘Music 2.0’ and very good it was too. However, during the Q&A, I found myself ranting about how the model of music as product is dead. About the only specific thing I can remember of what I said was “I make music because I must. I record it because it helps me improve. And I distribute it because I can.” If anyone reading this was at the session and can remember what I said in a little more detail, I’d love to hear from you.

This year’s EuroOSCON had no lightning talks scheduled. Then, late on Wednesday night, I noticed that a talk had been cancelled. Aha! I thought. I asked around a few people I knew who normally go for the lightning thing, got a critical mass of interested parties, went and found Nat and we were good to go. And it was good. Even if we hadn’t organized the session at less than 12 hours notice it would have been good.

In 2001, using an idea from James Duncan, who blames Damian Conway for getting him thinking on the right lines, I wrote a proof by implementation of the Extract Method refactoring for Perl. Though I say so myself, this was a Big Deal - Martin Fowler calls Extract Method the Refactoring Rubicon - once you have a tool to help you do that refactoring automatically, you can probably implement the rest of the Smalltalk Refactoring Browser and free yourself to think more about the interesting aspects of programming.

So, I heard myself telling a bunch of people at RailsConf Europe that the buzz about Ruby and Rails is the sound of “a bunch of Java programmers finally discovering how cool Perl is.” Which is normally the sort of remark I keep to myself.

Joel says Ruby is slow because it’s dynamic. Avi explains that dynamic languages don’t have to be slow and points out at cunning trick pulled by the Strongtalk VM to avoid hitting (slow) vtables on every method call. A trick which Ruby fails to pull. Joel declares victory. Hang on a minute… Maybe it would be victory if Ruby were already pulling out all the stops, including trick Avi mentioned, and was still slow.

Has anyone seen my passport? Update Found it! I shall go to EuroOSCON 2006. See you all there, or at RailsConf Europe.

I’m guessing that, if you answer ‘yes’, you’ve been for a meal at The Fat Duck at Bray, El Bulli or some place that does the Molecular Gastronomy thing with similar élan. We’ve just celebrated our tenth wedding anniversary a day early at the Fat Duck and… wow. I first got the giggles when we were given a small ‘Fat Duck’ cereal packet which contained some very lovely flakes of, we were assured, parsnip.

When naming a variable, method, parameter or class, give it a name that fits well with the language and concerns of the scope in which you are using it. Here’s some Ruby code: def test_can_load_unique_articles number_of_iterations = 8 articles = create_articles(number_of_iterations) do create_valid_article end assert_equal number_of_iterations - 1, articles.first.related_articles.size end … def create_articles(number_of_iterations) … end What do you notice about number_of_iterations in the definition of test_can_load_unique_articles? I notice that it’s wrongly named.

Well, not fishing, but… See you all in a fortnight.

Mmm… Priceline doesn’t suck does it? I’m now booked into a 4 star hotel about a mile from the conference and it’s costing me £33 + tax a night. Which is rather better than the best price I found anywhere else (including in the rather splendid sounding Chao Chow Palace on the outskirts of the red light district. I quite liked the idea of starting my day with noodles and a bowl of Congee.

I’ve been catching up with James Duncan Davidson’s blog and one entry caught my eye, coming as it did with a fabulous black and white photograph of Damian Conway <typo:lightbox img=“197468370” thumbsize=“small” displaysize=“medium” caption=“Damian Conway by James Duncan Davidson/O’Reilly Media”/> It’s a fabulous photograph. Gorgeous light, great composition, lovely. (Being an old film fart, I do miss the grain though. Digital noise just isn’t the same). It’s also a great example of why candid portraiture is so good; it would take a fair amount of skill, to get lighting like this deliberately.

As usual, substitute nails it.

“Good news! Those lovely people at Fotango, grateful for the use of the photo of their MD I took, have offered to pay for a EuroStar ticket to Brussels for EuroOSCON.” “Bad news! I still can’t afford to stay in a hotel.” So I’m going to play the shamelessly cheeky bugger card. If any of you fine readers is going to EuroOSCON and has a hotel room floor/unused half of a twin room/sofa where I can crash, then I would be delighted to hear from you.

It may not be a nice theme, but it’s my theme. Look! There are adverts again! Why not click on some of them? Ahem. Sorry about that. I shall shortly return you to more usual fare.

I just realised something about the workings of new style Typo Sidebars: it’s just an application of the Parameter Object design pattern; the render_sidebar helper method takes a Sidebar parameter object and produces a chunk of HTML. The fact that we persist the parameter object using ActiveRecord is almost beside the point - the persistence is more important to the render_sidebars method than anything else. Old style sidebars couldn’t really be called an application of any design pattern.
