You can't see them because the shutter speed is high and the aperture is small, because of the high levels of light (the sunlight shining on the lunar surface and on the astronauts). If you took a photograph on Earth during the darkest night with the same camera settings as used on the Moon during the daytime, you wouldn't see any stars either (or anything much in fact) because they are far too faint to show up with those camera settings.
Actually, Microsoft has abandoned TCPA citing a lack of customer and developer demand. I submitted a story on the 7th May about this, but it was rejected.
I wouldn't trust these things with my life. Ultra-lite also means ultra-flimsy sometimes.
Planes in the sport pilot category will actually be stronger than airliners - IIRC, airliners are only certified for +2.5G loading, I believe sport planes will usually be in the 'utility' category - certified to +4.2G.
I have a fair few hours in one of these one seater crop duster type planes (a Piper Pawnee, used to tow gliders). They don't qualify for the sport pilot license, but even if they did, you really wouldn't want to go too far in one. They are slow, very noisy (bugger all cabin sound insulation), and mile-per-gallon wise are quite uneconomical because they are designed to haul a load (large engines but low top speeds). The 235hp Pawnee is hard pushed to do 100 knots - a retractible gear 4 seat light plane of that horsepower typically will cruise at 150 knots.
Newer crop duster planes are even further from the Sport Plane category, the new ones often sport turbine engines in the >400 shaft horsepower range to carry prodigious quantities of spray.
Many of the requirements (especially when you consider something like a JAR PPL) make things more dangerous, not safer. Over-regulation often has unintended consequences: think of the maintenance issues - as it's so expensive to get useful safety improvements (mainly due to the expense of filing paperwork), they usually aren't done - so the onerous regulations make it more dangerous. It is really borne out by the fact that the GA accident rate is lower in the US compared to the UK, and US general aviation isn't nearly as regulated.
Well, you won't get any further on the anti-depressant point with the US FAA - it's still a disqualifying condition (even for things that don't need a medical, like gliders).
I don't think even the UK's NPPL (requires only a DVLA Class 2 medical - i.e. a driver's medical for truck drivers, which any GP can issue) if you're taking antidepressants, but I could be wrong.
The FAA tried something like this years ago with the Recreational Pilot Certificate - however, the requirements were almost the same as the full private (still need a full class 3 medical, nearly as many hours needed to qualify), and the rec. license was 'crippled' in features compared to the full private. It was hardly surprising that almost no one bothered with it.
On the second attempt, they seem to have got it right. The class of plane the Sport Pilot license addresses are non-complex, easily maintained and things happen slowly enough that even very green pilots shouldn't have a hard time handling them. Over-regulation has been killing general aviation for years so let's hope this gives the recreational end of it a good boost.
In the business world, the need for egress filtering (i.e. what they are calling a 'reverse firewall') has been needed and met for a long time. For example, my network's firewall only allows *out* legitimate traffic, rather than the typical NAT home broadband router which by default blocks in on all, but passes out on all. My default rule is block in on all and block out on all, and only open port/IP combinations where there is a definite legitimate need to be met.
Many people fail to see the value in egress filtering by default - most small-business network administrators see the obvious need to protect their network from incoming traffic from the Internet, but don't think about the consequences of a cracker getting in and being able to defeat your ingress filtering by having their machine listen to a port, and then remotely (say, via a webserver vulnerability) have a shell connected as an *outbound* connection to their machine. Not to mention that egress filtering helps you be a good net neighbour - if someone manages to run a trojan, it's at least contained.
I believe id Software use Linux as their development platform, so in all probability the Linux version will ship on the same CD as the Windows version.
Why can't they work on reducing friction to conserve fuel in the method you describe? It's against the laws of physics I'm afraid - so it would be a complete waste of DOD dollars (and is totally undeserving of them).
If you did use your hypothetical EM field to push the air out of the way, you'd still need at least as much energy to do it as just passively pushing it out the way with the vehicle itself. It would be less efficient because of the losses in the EM field generation systems anyway. The cost of the EM field generation system (in terms of weight and money) would likely be higher than using materials that can withstand the kinetic heating.
We have always lived in dark times; it's not specifically now. Humans are hard-wired to be nasty and violent and it takes a lot of learning to override that hard-wiring. It's not even surprising what's going on now - it's inevitable and it will never end.
A rather dorky friend of mine once said in his Slashdot JE, "World peace will only be achieved when every human is dead". Sadly, he's right.
The drawback of course is earlier versions of PHP were insecure by default (register globals on, no strict mode, no built-in taint checking). It was easy to write PHP code with serious security flaws (and I nearly had my server rooted thanks to one - the script kiddie exploited a bug in a user's PHP script, and used that exploit to run the local root ptrace_kmod exploit that existed in Linux 2.4.19 kernels). It was just fortunate I had patched that particular local root exploit - as far as I'm concerned local root exploits are potential remote root holes given an otherwise fairly harmless exploit in other code.
I prefer to call PHP "Pretty Hopeless Privacy" as a consequence. I still use it - it's a useful tool to rapidly write a site which doesn't burn too much CPU time - but I've had to write my own taint checking code and fastidiously make sure I use it.
I would disagree with you. Whilst we would have never got where we have now without the wheel, the cantilever arch, suspension bridges, nuclear reactors and aircraft, the computer is unique.
Our PCs are general purpose machines which can be other machines merely by describing what these machines are (the description of course being the program and data). A wheel is always a wheel. OK, sure it can be laid flat on its side and used to hold dirt and grow plants. A plane is always a plane. A computer however can one moment be a virtual World War II battlefield and another moment a businessman's spreadsheet, and the next moment a television, and another moment a radio. It can even do some of these things all at the same time. That's pretty damned versatile as a small box under your desk.
'The computer has made us all stupider for using them' is a statement without merit if you ask me.
It still seems to be wrong. It says my web server is in San Fransisco, CA. when doing a whois lookup on the IP address gives the correct location for the netblock (Houston, TX).
At the Oshkosh (a large GA event in Wisconsin) in 2000, I met the co-pilot of the Bock's Car, Fred Olivi (the Bock's Car was the Nagasaki bomber, named after one of the guys in the group whose name happened to be Bock). He was signing the book he had written. Most of the book is about his formative years, and the lead-up to the bombing and the training they went through. The appendices are fascinating - apparently the crew could feel the EMP through their tooth fillings as a tingle when the weapon detonated.
I've never killed a mobo, but I've had one killed by a faulty power supply. One day, my computer just turns itself off. So I switch it on. It doesn't stay on for long - no, instead, there's a BzzzzzzTTT...>KAPOW!KAPOW! sound), the video card error light was on solid, and an IC on both hard drives had melted.
I note how he says 'switch to KDE'. Since RedHat 8's 'Bluecurve', I've always preferred KDE - the 'Bluecurve' theme seemed to work really well with it (and at the time, KDE had some vital features that Gnome didn't - for example, it gave you feedback when an application was launching: I tried my Dad with the default RH 8.0 Gnome install and he'd double-click large apps a dozen times and get many instances because Gnome didn't have the little application loading feedback that KDE has).
I don't know whether Gnome still lacks this UI feedback, but if it does I'm not surprised that little touches like that made the article writer use KDE instead. And of course, Konqueror is an excellent browser.
It's utterly *trivial* to filter. Just reject email with Windows executables. Most companies are doing that now; my mailserver does it - it's not even hard. I have never got a legitimate email with a Windows executable attached to it.
We used to do something vaguely similar at my university. We had relatively few high-end Sun workstations (at the time, SparcStation 10s). There was 1 SS10 for four users in some of the labs - three of the 'heads' were inexpensive Linux-based X terminals. This was around 1993/1994 or so (whenever the SS10 was reasonably new). The xterms were built by a local company.
An x terminal isn't a bad way to re-use an ageing machine - an old 486 with a Tseng Labs ET4000 would be fine for a guest terminal, hooked up to the 'real' machine.

What's wrong with pronouncing router 'rooter'? After all, you don't say 'Get your kicks on rawt sixty-six' - it's pronounced 'root'.

Why not use port 587 (submission) - this is the 'official' port to do this kind of service on.

When's the last time you got a Windows executable by email that wasn't a worm/virus?
Just have your mail server reject all email with executable attachments. It fixes the problem without having to worry about antivirus scanner updates.
