IceTV judgement's impact on other data?
In case you hadn't heard, IceTV lost their case in the Federal Court. IceTV provide(d) an electronic programme guide (EPG) service commonly used by people with personal video recorders (PVR) that work like Tivo. In other words, you can say to your recorder "record The Simpsons whenever it is on" and the PVR, knowing the programme guide, can just schedule those recordings. Any time you want to watch some Simpsons, there'll be loads sitting there for you.
Fortunately for PVR users, there's alternative, though I suppose it's legally-dubious in that it uses screen scraping and the like to replicate the EPG. It works brilliantly though.
To my non-lawyerly eyes, this judgement seems rather far-ranging. It seems that basically any collection of data can now be covered by copyright, no matter how you recreate it. The court viewed the act of scheduling programmes on a television channel as a creative act. Having worked extensively with schedulers in a past life, I'd tend to agree, it is something these people agonise over. But I think the impact is going to be quite widespread.
For example, let's say I wanted to set up a web site that allows people to compare phone plans. I use publicly-available information about the various suppliers' pricing to build a database that is looked up to recommend a specific plan from a specific provider. This would now seem to be a breach of copyright. I work with people who design phone plans, and I can tell you it's a very creative process -- though perhaps not for the right reasons.
So this judgement seems to have impacts far beyond the commercial channels' obsession with preventing people form skipping their shitty, all-to-regular ads. It could, in fact, prevent efficient markets as in my example (though telcos go to great lengths there anyway). Is this a desirable outcome?

Well there's $5,000 saved
We've just saved $5,000 by deciding not to buy ducted heating for our house. Why were we thinking ducted heating? Well it's funny how the mind works, you end up on a path a long way from where you started. I'll step through it.
The house stays pretty cool in Summer, but it's pretty cold in Winter, so we were thinking heating. I've lived in far too many shitty rentals with draughts, no insulation and the only heating option being expensive, inefficient electric. London spoilt us for never being cold when at home.
So I started looking at gas heaters, the unflued portable kind, which come in around or under $1,000. Choice has a review of them and points out that they release CO and NOx, as well as water vapour, and the emissions can be bad for asthmatics (like Holly).
So I stepped up my thinking to a flued gas heater, to go in the fireplace in the lounge room. I didn't want one of these gas fire things that have the look of a real fire but don't actually do much int he way of heat. I want real heat, so I was looking at the nice fan-forced heaters. These start around $3,000 and go all the way up.
Now my parents have a brilliant ducted gas heating system in their house. It's lovely in every room in Winter. Prices for a small house like ours are apparently from $5,000, which was less than double what we were prepared to pay for the flued heating. You see how your mind steps up a notch without realising?
Anyway yesterday the quote came in for the ducted heating. $6270 including GST for a five-star efficient ducted system. We've ended up a long way from the grand or so I was originally thinking of. It forced something of a reality check.
If we spend a grand on a heater (actually should be a bit less) we can spend the rest on double glazing and upgrading our roof insulation. This has major additional benefits of Summer insulation and keeping out aircraft noise. To be completely serious, you only really need heating in a Sydney house for a month or two of the year. Nice to have for perhaps another month. Spending all that money for something used for a quarter of the year isn't sensible.
It's been an interesting journey, and has taught me that when you're looking at things you need to remember where you started. Go back to it and compare with the gold-plated option you're now contemplating.

Okay, now I miss London
Dave Cross just posted a link to the Programme for Opentech 2008 in July in London. While I've long missed all the awesome bands I've been missing in London, this is one of those events I really would love to go to.
There's really cool stuff like the stuff the mySociety guys going on over there. Hackers hacking government to make democracy work better.
I really enjoyed some of the random conferences I went to in London.
London Perl Workshop had really inspirational talks on people doing seriously awesome stuff in Perl.
Sadly defunct NTK put on a really impressive day called XCOM2002 showcasing people doing weird and cool shit with computers.
I'd love to start something like this here in Sydney. London, at the time, had NTK, which gave enormous amounts of publicity to really interesting geek stuff going on, which helped in getting the word out. Not sure there's the critical mass here, but there are certainly loads of people doing really interesting things.
Not sure how to get stuff going. I've certainly never made it to a Dorkbot here, so I'm as bad as everyone else.
Perhaps we need an NTK for Sydney? Who's up for starting one? I'd only be interested if there's some helpers. For geeks who didn't live in London between 1997 and 2006 (i.e., most of you) NTK (Need To Know) was a sarcastic weekly, purposely low-tech newsletter about what was happening in and around London. By and for geeks, particularly the charismatic Dave Green and Danny O'Brien. Wikipedia article.

Giant CRX City Pro: a year on
About a year ago, I blogged about my shiny new bike, a Giant CRX City Pro. I was very excited about the hub gears on it. A Mark Jones found my post and asked me about it, so I figure I should share my response for anyone else considering buying it.
Glad you asked because I wouldn't recommend it!
The bike itself, frame, wheels, everything but the gearing is brilliant. A mate bought the (somewhat cheaper) deraileur version and is wildly happy with it. It's a really zippy geometry, really wants to go.
The big problem is the Nexus internal hub. It's a real pain in the arse. I was won over by the idea of zero maintenance gearing, but that just hasn't panned out.
To fix a puncture, you need a spanner and end up covered with grease getting the wheel off and on. It takes ages, and you'll get it wrong the first three or four times you do it, causing further problems. Chain tensioning isn't exactly easy, either.
What's more, a couple of weeks ago one of the anti-rotation washers (the yellow one in this picture as described here by the late, great Sheldon Brown) had one of the lugs break off, which meant the axle rotates. Taking it into the shop tomorrow.
So while I was after a much reduced maintenance bike, it really hasn't turned out that way. I managed to seriously screw things up the first few times I had punctures, requiring shop visits to sort it out and show me the right way. What's more, you need to carry a spanner and end up covered in grease.
Longest ride I've been on? Dunno, not that far, maybe 50kms. It's my commuter bike, so it normally only does 10km a day. If you're thinking of touring with it, be aware that the lowest gear isn't all that low, so loaded up and going up mountains wouldn't be good.
If I were buying again, I'd buy the derailleur version of the bike. For the price and the quality of the bike, it's an amazing deal. I might spend the difference in price on a hub dynamo and light set.

Sun Lizard: any good?
%20on%20House-480px.gif)
We've been getting quotes for heating in our house, as it's starting to get cold. Initially we thought we'd go for a flued, fan-forced gas heater in the fireplace in the lounge room. A friend has the unflued gas heater recommended by Choice and it's brilliant. Heats her whole house really well. We figured flued because then the exhaust gases go outside.
Turns out gas heaters of this calibre, flued or unflued, are around $3,000 or more plus installation. Not cheap! So we decided to have a look at ducted heating, which if it comes in at under double that, I reckon isn't a bad deal since it would heat the whole house.
Now I've found The Sun Lizard which was featured on New Inventors. It uses heat from the sun to force warm air in or out of the house, depending on the season, and stores the heat in the thermal mass of the house. Given we're in a double-brick house, we've got plenty of thermal mass.
This claims to heat by 4-6° which sounds like it'd probably be enough most of the time for us. In addition, it cools by up to 10° in summer which would be a nice bonus. At under $3,000 it sounds like a nice option, and with no ongoing costs it's quite attractive.
But I'm not sure 4-6° is quite enough, even in Sydney's mild winters. I vowed when we bought a house to never spend another winter shivering with all my clothes on and a crappy electric heater sucking down expensive juice. This is the experience of poorly insulated, unheated rental properties for about a month a year in Sydney.
I wonder if the money we were thinking of spending on ducted heating might be better spent on a unit like this and upgrading our insulation. Get the roof vacuumed and the old insulation replaced with modern, high-spec insulation. As an added benefit, it would reduce plane noise. We're also looking into double glazing, which has benefits for both thermal and acoustic insulation. Perhaps with greatly-enhanced insulation and this unit, we could get by with a crappy electric heater used for only a few days a year?
So does anyone out there have any experience with this unit?
