digging yourself into a hole providing free support until they eventually toss that codebase.
Bug fixes aren't new features. If bug fixes are a huge burden then it's because the code's crap. They deserve to have to fix it no matter what the cost.
The car analogy would be like buying a car then having to pay extra to fix any manufacturing defects. Would you be happy with that? Manufacturers earn more for making shoddy cars than for making good ones...?
A state-owned 'idiot' list. That's an seriously useful database to have. If I was an employer I'd gladly pay for a copy of that. We could also cut back on their social services payments - if they've got enough free time to sit all day on the Internet then they don't deserve benefit handouts.
The $64,000 question is: Will you want to develop on such a limited machine.
Only time will tell how many people will find it unbearable but I'm betting it won't be long before most people who own a PC will be connecting it up as a slave and doing all the editing/compiling on the main machine.
(Which is fine... just let's not pretend it's something it isn't)
I kinda agree with what you say... but many shields are also available as breakout boards so you can just throw a couple of wires across from your perfboard arduino. You can even remove the headers from the shield and use that. (I'm sure you're aware of all this...maybe even done it)
What I really came here to say is that the 2012 Arduinos have full USB built in and are even cheaper than the old ones were. You can even get them without headers, saving a couple more bucks (and maybe some de-soldering if want to connect wires directly to them).
Yes, obviously, but everybody here seems to think the Pi is suitable for use as a cheapo Linux machine in classrooms or whatever. I'm pretty sure it won't work well for that because as soon as you open two or three windows it'll grind to a halt. I can't imagine trying to compile C++ with a browser and a text editor open (disclaimer: I haven't got a Pi to try it on so I can't say for sure how quickly it starts thrashing...)
The problem is that it's not happening on just polygon edges (where it would only be an annoyance). I'm using alpha-to-coverage for transparency so you get large areas of the screen where the framebuffer has only a subset of the samples covered depending on alpha (mainly trees). I can't test for zero/non zero because 'non-zero' can still be behind a tree (half the samples visible). I need to test for 'less than the number of multisamples in the framebuffer'.
Question: Are occlusion queries supposed to return number of samples or number of pixels in Direct3D?
Occlusion queries are supposed to return number of pixels in both Direct3D and OpenGL.
Cite? Most graphics cards definitely disagree with you, they return number of samples.
My program's been in regular use on many different graphics cards for a couple of years now. The problem only appeared last week in a when somebody upgraded their machine with a 'pro' graphics card.
I think they only bought Instagram because the IPO was looming. It could have wiped more than a billion off the IPO so in that sense the money was unimportant to them.
I think the only thing that could unseat Facebook to any great extent is a site that allowed adult content. People posting pictures of their genitals and doing that 'cyber' thing.
If a bureaucratic school board has to organize that then it'll cost way more than that.
And the static-sensitive issue is a major problem nobody seems to be mentioning. No kid can be given something and told not to touch it wrong. Kids simply don't work that way.
I guess you could tape them to the back of the monitor out of sight.
OLPC targeted Africa/India/Brazil, etc. Pi is targeting Bristol/Sussex/North Hertfordshire... no shortages of electricity, or even old cast-off computer junk like keyboards and monitors.
...except most of those monitors will have VGA connectors. Oooops!
How full-featured is that Arduino? Last I checked a decent unit was more like $17 which is a lot closer to $25.
The Arduino PCB is really just a breakout board for the ATMega chip with a serial interface on it. You can develop on one of those then solder an ATMega chip to a piece of perfboard for the final project. It doesn't need any external components (maybe a voltage regulator if you're using an unregulated power supply). The ATMega chips go for about $3 each - you can buy ten of them for the price of a Pi.
Slashdot Mirror
ie. It's a job for bimbos and their comments aren't proving otherwise.
Yep. Everybody I know who owns a Kinect is using it as a 3D scanner (or something similar).
Nobody plays games with them.

These comments should be funny...
Supposing they solve the remaining problems (eg. Sun going down), how will this be better than an airship (Zeppelin/Blimp)?
If it made it 500 miles I assume the problem was that the sun went down rather than any mechanical reason why it couldn't fly indefinitely.
Big advantage: They're easy/cheap to replace. Glass screens aren't.
I already have a plastic screen protector on top of my glass, so do a lot of other people. I don't see any problems with it.
Let's hope it isn't too wrinkly when it goes down again.
(It would cause distortions/refractions)
I'm not using XNA ... I use C++ and IDirect3DDevice9::CreateQuery(D3DQUERYTYPE_OCCLUSION,...)

Is there a way to choose?

How many of those 90% would jump on board if they head easy Internet access?

Maybe Facebook isn't for you but 99% of the human race seems to like it. That's what counts, not what a bunch of old-timers think of it.
Facebook is safe.
Moving all those photos, messages and contacts to a different site simply isn't going to happen.
Don't forget that Facebook can copy whatever the other site is offering before it can even gather momentum.
Here in Europe we already have a car called the "Mii"

I would like to build a custom-soldered board with LED's. I know that I may do something wrong, and overload the GPIO pins on the Pi.
I'd rather fry a Pi than an Arduino.
Get an Arduino with a socket. Replacement chips are about $3 each...
