For those that haven't come across it before the object-capability model deals with this sort of problem.

Edit: That of restricting each process to only be allowed to do certain things.
Oh and MathML would be nice.
That fills the same space as to what I was thinking about, cool! I'll have to try setting a course up.
I thought of some form of karma might be needed to avoid people joining a class and spamming the forum. But that is probably a issue for later.
More communication methods would be good. IRC server with a web client, and per class chat rooms that saved the chat logs.
The major suggestion I have at this stage is to separate the module from the class. So that different groups can follow the same module. Too many people following the same class would generate too much traffic.
I'd also though it would be nice to signal that you were willing to run a course if enough other people wanted to join a subject.
I also think that some way to create tests would be useful. Of course it wouldn't be under exam conditions, but it would be a nice way of seeing how you were doing.
You are basically setting up a community of some sort, which has the basic problems of.
1. Too quiet 2. Too Noisy 3. Attracts spammers/trolls
Be prepared to deal with these as you go forward.
I put my idea up (about the group learning community), because I'd like it to be made. Even if I'm not the one to make it. It scratches one of my itches.
> That isn't true; that ends up with the wall from the middle move in a different spot.
Oops yes you are right. They would only be of the same value if the map was symmetrical on the diagonal line going between the first position and the last one.
I wonder it they should be similar (at least in situations where you don't touch walls).
Did you do any sort of memoization of the minmax evaluation?
For example the expected value of moving up and left should be the same as the the expected value of moving left then up?
That would cut down the search space some. Of course it adds memory overheads.
You could also memoize the voronoi heuristic if that takes a long time to compute.
I hope to get a sheevaplug* at some point to be a small multi-purpose home server. If we can get setup of that (or something similar) to be as painless as setting up a facebook account and friending, we might be on to something.
I also want to use it for things like storing scanned images and possibly home automation/monitoring.
In short there might be a market niche for a low-power headless server to solve this kind of situation
What I'd like is a device that can fold (but has a seamless screen when unfolded) so it fits more easily in small places. Also you can type and have part of the screen angled up at you (this would still be an ergonomic nightmare for as a 6'4" guy wanting to improve his posture, but less of one than a purely flat item).
I'd also like one I can set up as a small tv screen (in-built stand) and remote mouse/trackpad so I can surf you-tube without having to hold it up.
Why are we talking about the Apple IIe? I'm sure a lot more people that learned to code and about the guts of the machine in the 80's did so on Speccies (£180 in 1984), C64s ($595 in 82) or Amigas ($699 in 1987) than on Apples/IBMs.
I was bought a Spectrum as a child (and saved up christmas money for an Amiga). My parents weren't at all technical. I learnt a bit of BASIC but not much (I didn't have the patience to program much), but I did get a decent understanding of what went on inside. So I was happy to build my own computers.
I'm pretty much the same hate stuff kinda mindset. So I'm curious did you get the DX or the original. DX seems more useful for pdfs/studying but less pocketable.
As the IPhone SDKs currently run on Mac OSX, if they kill OSX how are people going to develop for whatever the IPad develops into?
It raises an interesting question though. Is Apple slightly killing off their supply of future developers? If people don't grow up with programmable machines will the IPad generation be so into programming or as knowledgeable about computers actually work in general. I know a fair chunk of my knowledge has come from diagnosing and fixing faults in computers.
What about weight? For a paperback sized kindle it is about half the weight of a ipad... (300g for the kindle and 680g for the ipad)
It is fairly easy to find such mappings. Call the carried data the key. XOR the key data with any other image to get the encrypted file. Simply XOR the encrypted file with the key file to get the desired image.
Finding small mappings is another matter.
This is interesting. It might be worth noting somewhere how many bits is an Int on your test rigs.
I got 94 using C in 12min (didn't check for overflows of large numbers, silly haskell making me used to Integers).
Weird, I always though of xfactor single-buyers as young people (future pop wannabees) hoping to catch a bit of the star factor of the people they had been voting for.
Looking for more data I came across this
http://www.bpi.co.uk/members-area/article/bpi-statistical-ha...
It suggests that in 2008 95% of singles were downloaded. So I doubt the weather had much to do with it. Still no demographics on who actually buys cds normally though.
What are you estimating as the demographics for each?
As a 30 something alternative music type the RATM campaign was big on my facebook page. At least back in 2007 the xfactor was big with the 16-34 age group. So about the same age group, I'd have thought.

Poorer, I'm not sure. The Xfactor crowd does seem less geeky/bookish than the ratm crowd, from the people I have met.
What this all means I'm not quite sure. Perhaps we will see the start of micro payment campaigns. 40p to support some cause is not much. You just have to make it have wide enough appeal.
