at supersonic speeds (the nighthawk's max speed is only Mach 0.92, but at that speed the local airspeed over the upper surface of the wing would be transonic), things get a bit iffy. subsonic aerodynamics don't work at transonic and supersonic speeds. you get normal and oblique shockwaves, and supersonic nozzles behave like subsonic diffusers and vice versa. sharp corners produce less drag and heat than smoothly curving surfaces
rough surface increase drag, but it also energizes the airflow to make it less prone to separation at higher angles of attack
some aircraft have devices on the wings that "trip" the boundary layer of the airflow towards the trailing edge of the wing so that the flap angle can be increased further than would otherwise be possible without stalling
rough surfaces or boundary layer tripping devices (wires, vortex generator fins, etc) can permit huge lift/drag ratios, which are essential for large aircraft during landing
...and by sharing files i mean offering to others, not using myself (just in case you're stupid enough to assume my linux machine might be at risk of infection)
there are actually virus scanners on many linux computers though (such as clamav); usually mail servers that scan attachments that could be opened by windows clients
Everything I've told you is factual, trivially verifiable from multiple sources, and widely known by anything with even a passing technical understanding of the relevant systems.
It's widely known that Windows is a virus-prone piece of shit, but you can use it if you want to, and I'll continue to use Linux because I want to.
I've run Windows for 15+ years without a virus scanner
I wish you luck with that (I'm just glad I don't have to share files from you).
File permissions and virus scanning are completely unrelated pieces of functionality.
Just to highlight for you (maybe just to rub it in a little bit more - can't help myself), file permissions and virus scanning are related because one (the virus scanner) detects and in some cases removes viruses after they have already infected the system, and the other (filesystem permissions) prevents the viruses from being able to infect the system in the first place. They are both intended to combat viruses (that's the functionality relationship you're apparently a bit confused about), but one method is rather obviously better than the other. Virus scanners on Windows systems try (often in vain) to combat the threat after infection, and Linux systems never have to worry about virus infection corrupting the system (though if you try hard enough I'm sure Linux system infection is possible).
Viruses most certainly can infect system files if they are running as root
The problem with your statement here, while being technically true, is that the virus must be run as root. Unless you are a complete moron (granted there are a lot of them in the world) you wouldn't install a package off the web as root. In Windows however, a user simply clicks a button in a dialog box that they don't read and a setup program is thereby granted root/admin priveleges. Regardless of whether the dog has no teeth or its owner is a retard, Windows effectively has no effective filesystem permissions as long as the rediculous click-through previlige escalation exists. Real filesystem permissions actually prevent system files from being infected. That's the security of the Linux filesystem (along with the healthy lack of a bullshit eyecandy dialog box fetish).
File permissions and virus scanning are completely unrelated pieces of functionality.
i've already said how they are related, but you keep telling yourself that.
Windows system files actually have more protection (via both the superior permissions infrastructure plus other watchdog processes) than Linux ones do.
Nice try, but you're not going to sell Windows with that argument. Even consumers aren't that stupid anymore.
Viruses and malware are the bane of any windows sysadmin, but you're welcome to roll around in your own ignorance.
Meanwhile Linux will continue to power more and more of the world's corporate and web infrastructure, and it will do so on its merits rather than marketing and OEM deals. Shills must really hate that.
At the end of the day though, my obvious preference for linux over Windows will never change as a result of anything you can tell me (I don't believe anything you've told me so far), and my arguments here are more for my amusement from your reaction.
NTFS ACLs in Windows are considerably superior to traditional UNIX permissions.
that's why you need a virus scanner for windows, but not for linux. I think you're claim of windows permissions being superior is also frogshit, but it doesn't matter anyway (you use what you like, and I'll use what I like, and we'll agree to disagree).
Viruses can only infect things they have permissions to write to, just like in Linux.
difference is that i don't need a virus scanner for my linux boxes because the OS has set up file and directory permissions in a way that viruses can't infect the system... viruses can't infect linux system files because they don't have permssions to do so, but viruses can infect windows system files because there is no real protection for them (unless you feed Norton or McAfee shareholders).
if if (for argument sake) windows had superior filesystem permissions, they are like a guard dog with no teeth if they aren't set up to protect the system
hacking is different from malware infection. the whole point of having filesystem permissions is that it prevents access to files that enable getting root.
privilege escalation only works on non-hardened linux boxes, including setting shell for all non-human users in/etc/passwd to/bin/false (as a simple example). merely keeping your system up-to-date is another simple measure.
windows might have some kind of frogshit feature that Microsoft called "permissions" (read http://en.wikipedia.org/wiki/Filesystem_permissions#Differences_between_operating_systems), but there is no prevention of viruses infecting system files. if its easy enough for viruses to get around windows' filesystem "permissions" there isn't much point having them in the first place. real (and utilized) filesystem permissions is what makes linux less vulnerable to malware than windows.
shh.. you'll offend the entire corporate world, whose livelihoods depend on trademarks, patents, copyright, etc. (as well as violation of all of these)
what, did you think that companies actually made money out of innovation nowadays?
to my knowledge, only the Apollo Guidance Computer has ever truly achieved hardware failure tolerance. the Apollo 11 LM radar fault overloaded the computer, but was able to continue due to restart logic built into the AGC that was able to pick up critical tasks from where they were when the computer was restarted and drop non-critical tasks, and all with a very small fraction of the capabilities of current technology (although I think from memory they were able to fit 2 transistors on a single chip!). the AGC is really a marvel of (past) engineering and computer science. the reliability problem alone would be insurmountable with today's garbage. probably part of the reason why we haven't been back there since.

if we build an airplane as small as a scorpion, we can use cellophane for the wing because thinner wings are very efficient at low reynolds numbers
we can call it the "spruce moose"... now hop in smithers

the wetsuits used by olympic swimmers are apparently rough like shark skin
apart from roads etc of course

that would explain if a process suddenly ran like shit
hahaha "Internet Exploiter"... even better than "Internet Exploder"
btw... is it just me or are most of the apps on the Android market really crap? i would assume that the iphone equivalent is also full of similar crap
have the firefox peoples introduced the DOM file.lastModifiedDate yet?
I really need it for a project at work. Apparently Chrome has it but Chrome is evil. Aurora doesn't seem to have it yet (version 9.something).

Would you fly in an aircraft controlled by a Dell PC running Windows 7?
The flight attendant would tell you that you should arrive safely at your destination.
erm... not sure if you're joking or whether you really didn't get that i was referring to ipad (device) ripoffs
Now, they can threaten to stop building them in China. That's a threat.
yeah, cos that would reduce the competition for the local chinese ripoffs
