Yeah, hopefully they attach random bits to the PIN (padding out to the 64-bit block size) and encrypt that. That would thwart the simple dictionary attack.
Section 102 of HR418 (the bill in question) has two positively frightening clauses:
"Notwithstanding any other provision of law, the Secretary of Homeland Security shall have the authority to waive, and shall waive, all laws such Secretary, in such Secretary's sole discretion, determines necessary to ensure expeditious construction of the barriers and roads under this section."
"Notwithstanding any other provision of law (statutory or nonstatutory), no court shall have jurisdiction to hear any cause or claim arising from any action undertaken, or any decision made, by the Secretary of Homeland Security pursuant to paragraph (1); or to order compensatory, declaratory, injunctive, equitable, or any other relief for damage alleged to arise from any such action or decision."
So in a couple paragraphs, they've given the Department of Homeland Security (executive branch) the power to ignore laws (legislative branch) and not be held accountable in court (judicial branch) for it. Now, I may have been asleep in government class, but that sounds like you're disregarding the system of checks and balances which underpin our government.
Sure, they say it within the context of border security, but on the subject of rule of law and constitutional separation of powers, I can't see how anyone who has taken an oath to uphold the Constitution could vote for a bill including this provision in good conscience.
The wingspan of the 747-400 is 64.4 m, and the wingspan of the A380 is 79.8 m, not to mention that the max takeoff weight of the A380 is 50% more than a 747. Airports are definitely going to need to do some checking to make sure those extra 15m and 400,000 lbs aren't going to clip or crush something in the taxiway.
That said, LAX was quoted in one news source (can't find article now) as already planning to make the necessary upgrades for an A380 to land.
I can agree with that. Back when I was running PPC Linux on my iBook, I wasn't able to get as much battery life as in OS X.
Still, the charging time is really bizarre. I think from total discharge, my batteries take 1.5 to 2 hours to recharge (with the computer running!) and last about 3-4 hours even if I disable CPU clock throttling. Maybe the external power supply can't supply enough current. (Granted, this is all Mac hardware I'm comparing to.)
For $500, I can believe that this thing is both slow and lacking in storage. Some things I can't figure out since they only show one angle:
Sound device? Speakers? Headphone jack?
Ethernet?
56k Modem?
PCMCIA?
I would hope #1, #2, and #3, but the description doesn't give you any clues.
On the flip side, it is painfully honest about the batteries. It takes 3.5 hours (5 if the laptop is on) to charge for 1.5 hours of use?!?! What kind of batteries are these? NiCad? There is something seriously wrong here.
If you are a eligible for the academic discount, they offer a version of 12" iBook with a plain-old CD-ROM drive and no Airport Extreme for $900.
The normal 12" model with Combo drive and built in Airport Extreme is $950 with the student discount. So if you plan to add WiFi to the CD-ROM only model, you've negative the cost savings.
Some people work outside. I know an archaeologist who would kill for one of these gizmos to do data-logging in the field.
Bonus points if it can be powered on alcoholic beverages. Alcohol seems to be cheaper and easier to come by in strange places than batteries, electricity, or fuel.
There is probably one ethernet link between boards, so you need more bandwidth on it to allow multiple nodes on the same board to communicate off-board simultaneously. Since there are 12 nodes per board, 10 Gbps is almost enough to handle theoretical worst case.
Dunno why not 10 Gbps everywhere. If you maxed out the 400 MHz Hypertransport bus on the Efficeon, you could push out 1.5 GB/sec, which is just over 10 Gbps. I wonder how much that costs...
I think he is referring to the Halting Problem. The Halting Problem is basically: "Can you make a program that takes in another program as input and decides if the program ever halts?"
Turing showed that no such program exists that can solve the halting problem for all possible input programs.
However, it's a big stretch to go from that to debugging software. Even if you show that the halting problem is equivalent to debugging a program (assuming you can define that formally), you still can get around the proof by designing a program that only debugs some programs. There might be a very large class of programs for which the halting problem can be solved, and that could be enough for practical use.
Anyway, I'm just saying that one needs to be very careful applying things like Godel's Incompleteness Theorem or Turing's proof that the Halting Problem is not solvable. Those theorems are extremely formal and don't necessarily apply to practical situations where partial solutions are good enough.
(Another example is the Traveling Salesman Problem. No one knows a polynomial time algorithm that finds the optimal solution, and it is quite possible no such algorithm exists. However, there are polynomial time algorithms that will get you within a factor of 2 of the optimal solution, and I think there are others that get even closer than that.)
It doesn't save you money when you are the target of 800 lawsuits. That kind of drain on the funds of Maricopa County would more than outweigh any savings you could possibly achieve with his policies.
Sheriff Joe is an excellent politician, because he knows what gets him elected. It's "looking tough," not "saving money."
Pink underwear and Tent City gets you plenty of news coverage in AZ and worldwide, but Maricopa County paying out yet another prisoner mistreatment settlement ends up buried in the paper, if reported at all.

Not to mention that his never-ending stream of publicity stunts cause tons of lawsuits, many of which the county has to settle with cash. Regardless of the morality of his prisoner treatment practices, he's costing the taxpayers in AZ a lot of money and ignoring problems (like understaffing of prisons) which have a real impact on things.
Get yourself a Shuttle XPC with one of these and you can put your Athlon in your backpack.:) I use my XPC with my iBook as the X display for those times when I need more number-crunching power than just my laptop can provide.
They were only showing a picoBTX board. Go read the Anandtech BTX article to see the different BTX sizes proposed. The picoBTX form factor looks about like the small form factor motherboards in Shuttle XPCs. The standard BTX board has the same number of slots as you are used to in normal systems.
I'm pretty sure wake-on-lan is possible, but running your iBook with the lid closed is not very good for it. Using pbbuttonsd on Gentoo PPC, I once set the laptop not to sleep with the lid closed. Left for a couple hours while it did some stuff, and when I came back it was really hot! The iBook seems to be designed for heat exchange through the keyboard.
That said, it would probably be okay if you kept the load low. You can check out Screen Spanning Doctor, which, in addition to enabling dual-head support on some iBooks, will allow you to run the iBook with the lid shut in OS X. Be warned! The dual-head hack only works for some iBooks, and can damage others, so check the compatibility list.
To be honest, I don't know where you get these generalizations. By the time I read down to your post, I was thinking, "Man, why does everyone on Slashdot hate Starbucks?" And I've never, ever seen anyone bash Barnes and Noble on Slashdot.
So you're left with Microsoft, which I can't argue with.:)
The precession of Mercury's orbit is explained by the general theory of relativity, not the special theory. The special theory explains the results of the Michelson-Morley experiment.
Random manual verification. Sure, it's only a statistical assurance, but one could do a cost-benefit analysis to determine how much assurance you want.
(Think of it as setting error bars on the poll results. Do you want to be able to believe the results to 5%? 1%?)

I think he's referring to Erdos' use of amphetamines to improve his work. Search for it in the Wikipedia article.

It is C. The request was to add an item to a singly linked list in the language of your choice.
Which is slightly contradictory, since releasing under the GPL would not prevent commercial use.

Forget "eBooks." Just make me a tablet that can run Safari and Preview, and I'm set.
