Amiga nostalgia ftw

This Slashdot discussion made me go back to see and nostalgize my pinnacle of Amiga programming - PPT, an Image Processing Program. Taught me everything that I know about multithreaded programming - and I did it without protected memory or any resource tracking :-). Those were the days... Unlike many others, I tried to stick within the RKMs and refused to hit the hardware directly (though an occasional assembly routine here and there never hurt anyone).

One thing I'm fairly proud of still in that code are the RGB -> HAM/HAM8 conversion routines. HAM was this curious Hold-and-Modify mode in which you got to change only one of the RGB components, all the other ones were picked from the left neighbour pixel. Since that meant that in HAM you could only have 16 base colors (4 bit plans) and in HAM8 64, choosing the right palette was really hard. Many people just stuck to a preset palette, and tried to match it, but my routine built a histogram of the image and tried to choose the best possible palette. I still occasionally receive comments about how great the images look - though it's now been a couple of years since the last one - but for a program which hasn't seen active development since ~1995 that's pretty good.

Anyhoo, enough nostalgia. The code is GPL and available in this SVN repo if you want to see how badly I used to program. Lots of C code there... The HAM conversion routines are here and here.

Who really is iPad's competition?

IPads and other web tablets (which will surely arrive, now that the tech is at a level where they have become feasible and everybody loves to copy Apple anyway) will have an interesting competitive situation. On the surface, it does not appear that they have competition. Some people are pitching them against subnotebooks; some are saying that they are iPhone competition (which I think BTW is insane). Some people say that they will kill the personal computer as we know it.

Well, I've been thinking (which became my favourite phrase after @MikaelJungner said that every time he utters it in the Finnish Broadcasting Corporation's management team meetings, everybody starts screaming). Perhaps the real competition is the television.

I have a few arguments. First, the situation is analoguous to the early days of the mobile phone: everybody had a fixed landline, which was shared. It was in one place, and everybody had to take turns. Much like the current television set: it's in one place, we usually have one room which enshrines it in some way, and you only watch one channel at a time. Yes, now, if you find this a problem, quite a few households especially in the Western countries own more than one television these days, which makes them personal televisions. But they're still largely immobile and tied to one place.

The second argument is that media industry loves the iPad. Here they have an opportunity to keep going what they already have, outside of regulation, and have total control of who watches and what. No more worrying about the analog hole, because Apple doesn't care about interop. They will control, together with Apple, the entire production chain from source to screen. No need to change business models or worry about privacy.

Now, if pad computers become personal television sets, that means that the advertisers will get extremely accurate data on who saw what and who bought what. The knowledge that is accumulated in the Apple App Store and iTunes Music Store about consumer behaviour is simply the best data available anywhere on the planet, except perhaps for the data collected by Google. And people give this willingly and even pay for the privilege.

The fourth argument is the fact that internet distribution is way superior to broadcast. Get what you want, when you want.

The fifth argument is that people are getting very much used to now living in a virtual world. Smartphones and computers have given people the opportunity of changing few but intensive connections to a large number of less intensive connections - and people have chosen those en masse. Just look at how there is always someone who fiddles with their Apple/Blackberry/Nokia/Samsung wherever you are. So losing one of the bastions of togetherness in the living room doesn't sound that bad anymore. (Though this is a fairly controversial argument - I think that it might actually be good that living rooms become living rooms again as opposed to consumption rooms.)

The sixth argument is that TV set makers know this already. The new high-end TV sets have integration to Youtube and social media services - but I think it's not going to work. TV sets aren't personal to the degree that social media would work on them.

The iPad form factor is excellent (though the bloody thing is still way too heavy, but that'll be corrected in a year or two) for snuggling in bed and watching telly. It doesn't heat up the same way a laptop does; it doesn't keep noise like a laptop does; and it doesn't bring in the cognitive complexity as a laptop does.

So I'm going to hazard a guess here: pads will be the personal media centres for home, killing off television sets the same way mobile phones killed landlines. They won't kill television as such, because moving to the iPad is the path of least resistance for the media companies, but it will punish them because now there will be a new distributor in the chain who will grab a bite out of every sale.

Inner Circle

After many years of claims that it exists, the ├╝bersecret Finnish Bloggers Inner Circle was finally formed now that nobody really cares. I'm trying to let the world know before the "Swords of Jesus" come and take me away. Run, before it's too la
