Well, if it's a thick layer, that might be difficult. A thin layer on your visor might obscure visibility a bit. Naturally, the solution is to live underground, run pipes over to the hot side for power, and use UV lamps for growing your food in your underground oasis until the planet spirals into it's sun.
Minor details. I mean, if you can't handle breathing a little metal vapor (or building a respirator to filter it), what kind of space explorer are you?
My understanding is that a bunch of them "defected" to AMD shortly after Intel acquired the DEC/Alpha technology, but I don't have any confirmation of that.
In case you haven't noticed, companies have been trying to make a tablet computer for 10+ years. The iPad finally showed people it could be done and now everyone is scrambling to come out with something competitive. Wait at least 6 months to see what comes out, because right now, there is very little selection and the chances of anyone getting it right on their first attempt is pretty small.
And the keyless start cars are the ones the article is about. It's completely passive, and that's the fundamental problem that makes this attack possible.
Apparently you didn't read, or failed to comprehend the article. They are not intercepting or decrypting the communication in any way. This is a relay attack in which they use a type of RF repeater/extender to allow the car and the key fob to communicate at much greater distances than intended. In doing so, the car's "thinks" the key fob is in range and unlocks the doors and starts the car. They're simply extending the range of the "proximity", the car and key fob are doing exactly what they're intended to do, passively communicate, unlock the doors, and start the engine.
Your comments about time are particularly useful to explore. My comments below are for those who claim that our science is sufficient to claim that they don't exist.
Despite the many comments asserting we know a lot about the forces of the universe, there are several aspects of spacetime that we're clear that we know very little about. The force of gravity is one, and the nature of time is another. Sure, we know about relativity and how an object can experience time dilation, and in theory, the equations allow for time to flow backwards, but we have no idea how that would ever be possible given everything else we know about the universe. We don't even have any strong theories for why gravity works, only how it applies. We don't have any explanations for quantum entanglement, but we can reliably demonstrate it (now, even though we couldn't 30-40 years ago).
So, given that we really know almost nothing about time other than how we measure it and how it can be slowed via time dilation, how can anyone assert that we know enough about the forces of the universe to determine that all our previous tests have virtually ruled out any evidence of "ghosts". Are we looking for the right type of energy? Do we even know what type of energy to look for? Are we looking in the right time? How could we detect a communication "across time" (from the "past" or "future")? What would the signature look like? What sort of energy would you look for? What type of instruments would you use to detect it?
Despite all the progress we've made in understanding physics and the forces of the universe, there are still several major things that we observe all the time that is well beyond our best science to explain or prove, so it's absurd to claim that our science could/would have already detected a ghost if they exist. The most we can say is that at present, our current science hasn't been able to detect clear evidence of one, therefore, from a scientific view, it unlikely that ghosts exist.
You're correct that a system that limits the response time window can limit the range to which a signal could be relayed. However, such a system needs to have a key fob that responds very quickly and with a very repeatable delay so that the total response time (fob response time + signal propagation time) can be tightly regulated.
A much simpler, and more reliable solution is to eliminate the passive nature, at least the passive start feature and/or require that a physical key be inserted and turned before the car can be driven. If it required some non-passive action from the user, such as pushing a button on the fob or inserting a key, this attack would fail (or at least be significantly more difficult)
Any security system that relies upon passive proximity using RF will be hackable using this technique unless they can get the timing down to restrict the range to under 10m, preferably under 5m.
It's not a replay attack, it's providing a transmission conduit that extends the range of communication between the car and the key fob. The car and key are in fact communicating, and there is no interception or decoding of the signal needed. It's an attack on the "proximity" based feature of these system.
My first language was BASIC, my second assembler. Since then, I've learned at least 6 more languages, but I still prefer a modern compiled BASIC for most projects. On the rare occasion that BASIC can't deliver sufficient performance, I'll link in some assembly or C routines. I've been quite successful doing that professionally for almost 26 years. That doesn't mean I always write in BASIC, I use the language that best fits the needs, the majority of the time, that has been BASIC.
Mind you, I hate old interpretive BASIC languages that require line numbers, don't have DO/LOOP, WHILE/WEND, Sub/Proc/Function calls, variable scope controls, and other necessities. I'm talking about modern compiled BASIC languages with most of the modern structures we all know and love. It's not a perfect language, but it allows me do code, debug, and modify far faster than any other language, and for most purposes, performance is close to any modern language.
An even better example of efficiency is a roller coaster. Typically one or two queues all the way to the loading platform, where people are then directed to very short queues for each row of seats. Substitute checkout lanes for the row of seats, and you have a very efficient system.
He's correct that in theory a single queue is most efficient overall, however, that doesn't scale well beyond about 8 registers. Fry's Electronics is a great example. The time it takes to walk from the queue to the specific register that is open is wasted time. So, when there are many registers, multiple queues that feed each bank of registers are more efficient. To make that optimal, or nearly optimal, you can start with one line, and split it as many times as needed to have people ready and waiting near each of multiple clusters of registers. There should be at least 4 registers per cluster to minimize the impact of a delay, and no more registers than can be accessed quickly from each queue outlet, which is typically no more than 8 registers. This is similar to the system used at ski lifts. There are multiple lines, including a "singles" line that gets as many people as practical on each chair.
BTW, Best Buy uses a single line setup, at least during busy shopping periods, so it's not just Fry's, banks, and DMV.
Given that using current knowledge and theories, there is no way to get information out of a black hole, we expect to remain ignorant about what actually happens inside the event horizon. Hawking radiation provides some hope that it may be possible to obtain some information from inside the event horizon, but right now, even that seems unlikely.
Those applications are exactly why I wrote this email signature a few years ago:
If it were up to me, computer keyboards would not have a caps lock key. Everything would be lower case unless you deliberately hit the shift key. Not only would this decrease the amount of SHOUTING in emails, but it would force all of those programmers who only allow upper case input to go back and fix their lousy programs.
The main drawback to this is it might inspire *nix programmers to write more programs that only accept lower case or are case dependent. Therefore, we might have to create keyboards that randomly switch between upper and lower case unless you're holding down a modifier key. This would continue until programmers have been so thoroughly trained not to write unnecessarily case dependent programs that the very thought is considered evidence of insanity.
Of course, the second paragraph is just me being sarcastic. Realistically, there is no need for a caps lock key. A caps lock function can be implemented using either a double tap of the shift key, with the next usage of shift removing caps lock. In this fashion, it would work similar (but not the same) as the shift/shift-lock on older typewriters. Once it's locked, pressing shift again releases it. Alternatively, you could use a modifier key with the shift key for a caps lock function. ctrl-shift, alt/option-shift, or fn/func-shift.
For a couple years, I've had the caps lock key on my Mac keyboards reassigned as a control key. So, yes, I'm in favor of this.
Journalists do research and WRITE stories. Wikileaks just publishes documents that are leaked to them. They are a publisher, not journalists, and they don't appear to be particularly selective about what they publish, which is turning them into just a junk vendor.

I like it. If I had mod points, you would already be at a 5 - funny.
Of course, if it's tidelocked, there is probably a ring slightly on the dark side of the equator that isn't hellishly hot or cold.
...and at great expense
Thanks, I forgot that part
Of course, we are talking about government here, so naturally it will be at great expense.
...to stop the leaks after the first leaks, have just been sacked. The leaks will now be stopped in a new, and completely different fashion.

I mean, for all practical purposes, it's an infinitely small number, so why shouldn't it be an infinite loop?

Today, it makes about as much sense as North Korea hosting a conference on human rights. And, yes, I live in the Unfree States of America
