Well, the Airport Extreme I use logs all of its various activities, including connection attempts (successful or otherwise) as well as access to the disk that is hooked up to it and I view it on the device itself or export the logs for more thorough review. I'm sure it's far from the only consumer grade AP to do this.
Now, I don't think it can go beyond simply letting me know that someone is trying to get in (beyond MAC filtering which is like trying to block a burglar by putting up a sign that says "do not rob this house if you are wearing red shoes") and having a strong WPA/WPA2 password, but if I was seeing large numbers of failed attempts on my AP I'd at least start doing some investigating.
Let me guess, you have an MBA, and your children have to justify why they should receive love and support from you.
The benefits of the space programme are numerous, and the funding is a drop in the bucket financially compared to most things the US sinks money that don't have to "justify" themselves nearly as much.
The shuttle itself is a big bus that was expensive to run, but we didn't start out making cars that released no pollution, had high reliability and could be effectively mass produced, did we?
Just off the top of my head, there are composites used in the motorsport and regular auto industries that came directly from NASA research. So I'll submit "modern cars that use composites" as a "tangible thing" that can directly linked back to the shuttle.
It was in the rest of the world. I remember visiting the US thinking "cool, I can stock up on cheap MD discs since everything is cheaper than in the UK" and was amazed to find that the media was expensive since no one seemed to be interested in the format. It was a superb replacement for tape at a time when no one had even heard of "mp3s".
None of the "pro" MD decks Sony released (which are still used in radio - they are common in the industry) had the stupid SCMS copy protection that was mandated on the consumer hardware, but even with that limitation (unable to make copies more than one generation down using optical/coax digital connections) it was awesome.
Lots of people moaned (as does TFS above) that "I just replaced everything with CDs and now there's this?!" but it was never designed to replace CDs - it was designed to replace analogue tapes - a task it excelled at.
I still use my MD deck from time to time. Enough that it's plumbed into my audio setup (via optical connections - I don't have to worry about "evil proprietary" ATRAC).
Well, it happened now, and 20 years ago... and then 400 years back in time before anything even resembling water (frozen or otherwise) falling from the sky.
There are areas of Antarctica where it hasn't rained for 40,000 years. It is one of the driest places on earth because very cold air can't hold much humidity at all.
Sure, they have a code of conduct that they require of their suppliers, and it includes higher wages for those who work on Apple products in factories where vendors' products are made (eg, Foxconn, making Apple, MS, Sony, HTC, Nintendo etc).
The suicide rate per Foxconn employee is lower than the national average - should they take credit for that, or share some of the credit with MS, Sony, Nintendo etc who all have products made in the same building (but pay the workers less than the contract rate Apple gives).
Yes, but like you said - restricted to specific colleges, so all of your local university friends could sign up at the same time and participate together at the same time.
Yes, but when it was all.edu addresses... crucially that was all your local university friends at once, when it hit a new campus.
Right now I have a spread of people who are all "doing the new thing" in G+, with the other half unable to participate - the likelihood is that the ones in G+ will drift back towards FB, where everyone is all on the same system, especially if there are showstopper bugs or it takes too long for invites to get going again (a friend has an update and is unable to sign up).
The salient point being "social networking site" that they've been hyping, and advertising... only to not let you in.
If that was a discovered bug, then why not mention that - the message I got was "we're full at the moment!".
The entire point of launching it is surely to get users and generate interest, if they truly do want to "topple" facebook. How many people are going to keep checking back after getting turned away during the big launch phase where it's all fresh?
Yes, my friend got one of those invites from someone already "in", but Google told her that it was full when she tried to claim the invite and set up an account.
I thought I'd have a look, and went to the page where it asked me to log in with my google account. I did so, only to *then* be told that you can't join up!
I understand they're in beta (hey, what google product isn't in perpetual beta?!), but the point of a social network is to attract and maintain users. Right now, all the buzz going around quickly dissipates from people when they reach the doors of the country club, only to be turned away.
A friend of mine received an invite for it, but she cannot make an account since "they are full up right now".
Google lacking server power and/or bandwidth? Say it ain't so! I suspect they want to play on the "exclusivity" thing to make people want to join up - it worked for gmail (but I suspect a lot of that success was because it was a genuinely better free email service than Hotmail and Yahoo), but did not work so well for Orkut (remember that?).
You can keep it in a dewar - we can make some extremely effective ones. The ones used on Apollo back in the 60s could keep hydrogen and oxygen liquid for moths with minimal boil off because they were so well insulated. The problem is that they're large, heavy and potentially fragile, especially for keeping the real chilly ones cold (oxygen, hydrogen, nitrogen, helium).
I would bet that it would be trivially easy to design a tank that could keep liquid hydrogen cold with minimal energy consumption and low boil off HOWEVER, there is no way I would want one in my car - it would just have too many question marks for safety. (Plus the practical concerns of liquifying hydrogen in the first place just to use it as a fuel, which is very energy intensive to do).
There's a huge dewar on wheels in the lab I work in that is as about the size of Wendy House with helium in it - the temperature inside it is 4K. Just because there's nowhere in the solar system that's naturally that cold doesn't mean it's not "relatively common" by human standards - I walk past that thing multiple times daily and barely give it a second thought.
Yes, gasoline is a flammable liquid with a high-ish vapour pressure at room temperature and pressure...
Hydrogen is a gas at room temperature and pressure, and an extremely low density one at that (in fact, you'll struggle to find a less dense gas - it's the lightest element, but exists as a molecule, still helium is more dense, the next closest).
What the GP was mentioning was the assertion that pumping liquid hydrogen at a filling station would be "safe and easy" (in comparison to gasoline). Liquid hydrogen is a cryogen - that boils at -252C (-450F), so not only is it a) very energy intensive to liquify (either by pressurising and chilling, or just chilling), it will furiously boil when pumped up out of the dewars you keep it in.
The only real way to "safely" store it (without having to consider cryogenic issues like venting, ice build up on the outside of valves and pipework, extensive lagging and bulky dewars etc, is to store it as a compressed gas.
The problem with that takes us back to density: it has a very low energy density, so you need very high pressures to store lots of it (ie, enough to give you similar range to gasoline).
You certainly won't be pumping it as a cryogenic liquid out of a fuel pump into your car in the same way you currently pump gasoline, and to think that liquid gasoline and liquid hydrogen are broadly similar in safety (in terms of the precautions and risks involved in storage, usage and handling) as you suggest with your flippant and uninformed statement that starts with a sarcastic "wow" is just laughable.
The major research right now is "how do we increase the energy density?" - we had effective hydrogen fuel cells back in the 60s - we sent them to the moon on Apollo, but they had to be fuelled with LOx and LH2, which was hazardous, but handy since they were using millions of gallons of the stuff anyway to power the rocket engines themselves, bleeding off a little to run the fuel cells was just a bonus. We simply can't do that in a consumer vehicle, so we need a way to carry enough hydrogen to make fuel cells really worth it, hence research into new polymers that can "absorb" it like a sponge, or new materials that enable us to make higher pressure storage tanks etc.
It will install onto a blank drive - you only need 10.6.8 (or higher) to be able to download it from the App Store. You can then save that onto a USB stick or burn to DVD.
You don;t need to put Snow Leopard back on, and then upgrade over it immediately, it will simply install onto a fresh drive if you want to, eg in the case of a drive failure or upgrade, or installing onto a second volume or into a VM.
I am being funded *right now* by an oil company for work into more sustainable chemistry for energy reduction, resource preservation and higher quality product - all part of "green" or "sustainable" chemistry.
Just because they have an agenda doesn't mean they aren't complex beasts. You wouldn't believe the amount of money that oil companies sink into universities.... that doesn't go towards "prove global warming wrong". Perhaps they are looking for other profitable areas of business?
If you think the computer models are "basically guesses" then you are grossly misunderstanding the way they work, or are wilfully ignorant. The reason we tend to agree (scientists that is) in the computer models is because we test them as best as we can.
The ocean temperature model, for example. We programmed it, gave it historical data, did small scale tests etc, and then asked it to model the next decade. Then we went an measured that decade (and did not tell the computer about these future measurements so it could refine or "cheat"), and what do you know - ten years later the model pretty closely correlates with the observed data.
You can do this with earlier data too, by cutting off the computer's access to data you know is real (because you measured it) and asking it to "predict" the past from a particular point and seeing if it matches or closely models what actually happened.
That's how models work. You test them with data that you have and refine them so that they're more than simply "fancy guesses".
Now, they are not perfect, and something as large and complex as the climate is difficult to predict over increasingly long timescales, but it's not like we're simply shooting in the dark while blindfolded. We know a great deal about it, and have more than just computer modelling to tell us what is going on.
Obviously not, since it's trivial to enable for non-Apple devices, and Apple gets to "keep the weight down" on iOS. Have you seen the size of the printer drivers folder in OS X?
Leave that to the desktop machine, and put something streamlined in iOS. Basing it on CUPS (like their whole print system) just makes it easy to interoperate. "Gratuitously proprietary" would have been to make it use some totally secret, non-standard, very-difficult-to-reverse-engineer protocol, instead of say... zeroconf and CUPS.
It is in fact the total reverse of what you just said. You can now share a non-Airprint compatible printer using a non-Apple machine serving (ie, Ubuntu in this case) so that your iPhone/iPod/iPad can't tell the difference.
It's hardly surprising, given that Apple uses (and maintains) CUPS and is very fond of zeroconf.
