Not for the tourist, but for NASA. Look at it this way, the space station costs 40 billion dollars (when you consider the space shuttle expenitures to put the thing up and service it), holds ~3 people, and has a lifetime of perhaps 10 years. That means that each person-day cost us, the taxpayers, 4 million or so.
Yet the Russians aren't giving the money from the tourists to Nasa, they are just paying for part of their own costs.
Set top boxes often have to provide anticircumvention as a legal requirement for the media they are using. For ANY GPLv3 device "No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.". That right there is a dealbreaker.
And what electronic devices support NO updates? Even my "car", as a sealed box, has some degree of upgradability on the electronics. If the choice is NEVER be able to update or provide open access, you can not build many viable businesses as a "sealed box".
The GPLv3 is deliberately anti-business. Why should people be shocked when business attorneys figure that out?
This article is FUD, but it is actually well founded FUD.
EG, the GPLv3 is specifically designed to limit the "set top box" model, as the provider can no longer treat it as a sealed appliance if GPLv3 code is involved (the anti-TiVo clause).
The GPLv3's patent liscence clause is deliberately broad:
A contributor's essential patent claims are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, control includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
Likewise, the recent lawsuits have made it clear that the FSF crowd has grown more willing to carry the GPL into court, and as another poster mentioned, there is the ExtJS's use of the GPL: Since the Javascript gets into the final product (the page), you can argue that by using ExtJS, your web site page, as rendered, is now GLPv3, the same problem Bison used to have before they changed it from being pure GPL, not to mention the attempt to "atheroize" the GPL because of the "googleization" problem.
Encryption doesn't help. You can participate as clients of a swarm to get the identity of the members of the swarm, which is the information the ISPs need to block the swarm.
As I contemplated when AT&T started saying they want to fight piracy on the wire, the most effective way is for the ISP to cooperate with the MPAA, where the MPAA gives a graph of "These people are exchaning a large copyrighted file, block it".
If ISPs move in that direction, this defense won't help, and thats probably the bigger threat for blocking P2P piracy, as there are always countries of convienece to set up piratebay like operations.
ISP conflict will remain, it will just become more subtle and more neutral.
You see, 50% is not good enough from the ISPs viewpoint: That still requires just as many bits crossing the ISP's boundry as if the content provider used UNCACHED HTTP.
In practice, many (most?) ISPs use transparent HTTP caches, so having 50% of the data stay internal is still no good, as on popular files (eg, a big youtube video), 99% of the traffic stays internal for HTTP.
Even PERFECT P2P requires at least one outbound copy for each inbound copy, so a PERFECT P2P system will require 2x the traffic crossing the border when compared with HTTP thats cached.
Since its one of the 1 GHz processors in the board, TDP is 5W.
Depending on what power-feedback is involved, the processor might actually just go "I'm overheating, throttle back" and drop down to say 500 MHz at 2.5W or so. The MPEG decoding shouldn't even take too much power, since the CN700 chipset includes hardware MPEG2 decoding.
As a bonus, the box is OPEN, which improves the cooling.
"You fell for one of the classic blunders, the most famous being 'Never get involved in a land war in Asia' but only slightly less well known is 'Don't use poorly seeded pRNGs in cryptographic protocols!' HAHAHAHAHAHHAHAHAHAHHAHAHAHAHAHA!!!!
You've got the energy cost in growing the raw sugar, transporting a LOT of raw sugar, and distillation. WHich means a LOT of energy goes into this. And you only really save on taxes (beacuse otherwise, they could just do this in a big factory and bring it too, duh, gas pumps).
Quote: "Adobe makes the official Flash plugin, but OLPC cannot ship it on the XOs because it is legally restricted and doesn't meet the OLPC's standards for open software. Instead, the XO ships with Gnash, an open source Flash plugin that can play some (but not all) Flash content. As shipped on the XO, it cannot play YouTube videos. Skilled users can rebuild it to include that functionality."
The Sugar distribution's exclusion of Flash, and only shipping a crippled version of Gnash, is all about open source politics, not technical performance limitations.
A: The x86 used is already very low power and very high integration, supporting sub-millisecond sleep states. With Amdahl's law being what it is, replacing the processor with a mystic 0 power CPU wouldn't add all that much to battery life. The TOTAL power consumption is 5W already, and the CPU's share of that power budget (when you consider CPU and not the associated control logic for memory, IO, etc) is low.
And in return, x86 compatibility is a good thing, because it opens up a huge world of binary software. For one, x86 is far better supported by just about everybody.
B: The OLPC actually uses a 15 W-Hr LiFeP (Lithium Ferro-Polymer) battery. Which is actually 4x the charge lifespan of LiIon, and has far greater environmental tolerance, and can even be composted for disposal.
The software stack may be questionable, but the hardware is brilliant.
Nothing else comes close for efficiency, cost, battery life (with working software), ruggedness, total lifetime, etc.
The thing is VERY tough (i've tossed mine several times), very low power (3 hours battery life with 100% broken power management. Good power management should get 6+ hours battery life for typical users), with a brilliant screen. Just put real software on it and its very nice.
Let alone the environmental tolerance: Normal notebook batteries die if you try charging them at 100F.
As someone who thinks the hardware is brilliant but the sugar software stack is an abomination, having the leading driver behind the abomination give up and leave because the XO is getting too close to BorgLand is a good thing for the project's viability.
An XO running XP which is modded to run at the screen resolution (unlike the ugly Classmate "scrolly-screen" hack) would be a nice platform.
Nevermind about my previous comment. Doing it as GPLv3 is genius!
By dual liscencing it as GPLv3 or a commercial liscence, commercial developers will ONLY touch the commercial liscence version. So they get paid, which is what they want.
Yet GPLv3 (instead of LGPL) is perfect. Its a "Poison pill" to commercial use of the library without buying the commercial version, yet gets the open source community behind you. Furthermore, by requiring copyright transfer for anything put back into the source tree, they get the work of the open source community to improve their closed source liscenced library.

The case fan is on the heatsink. So closing THIS case would greatly reduce the cooling, as hot air would be trapped in the case.

you forgot the *8 to convert byte to bit.
Thats a HELL of a lot of porn/pirated material.
8 GB a day is a crapload of data.
In fact, thats 800 kbps SUSTAINED USAGE, 24/7!
Anyone shifting that much data is probably violating a huge number of TOS clauses anyway.
When your character is able to get drunk and discovers that he DRIVES LIKE SHIT!
I remember the drunk mission in Vice City. Man, that was HARD!
The tax savings are SMALL.
.184 $/gallon, and another ~.20 $/gallon. So you could save only .40 $/gallon.
.8 gallons of gasoline.
EG, in CA, you'll still have to pay sales tax on the raw sugar. So your only savings are on the dedicated gas taxes:
With the federal gas tax at
While if you could do Ethanol for $1/gallon production, you could make a fortune, as thats energy-equivelent to about
So that would be "make gasoline at $1.25/gallon". With oil prices NEVER looking back, thats a LOT of profit to be made.

Thats my point. They don't want the "give back" portion, they WANT the poison pill.
If you want to encode your business logic, you need to buy the commercial liscence.

Buf if its GPL, as a library, NO WAY IN HECK.
GPL is a horrible liscence for a library if you want people to use it in a variety of places.
