I don't think it is "inverse square from the projector to the screen and inverse square back". I think the inverse-square law for light is radiation from a point source, i.e. it describes the drop-off in illumination as the light spreads out, rather than attenuation per se. When you're focusing, you're causing the beam to converge on a particular spot (the screen) which is a different thing.
Thankfully, as I have a reading age greater that 7, I can spot a trojan. Keeping my system updated or running updated AV won't make a difference to that.
So it seems youre also the sort of idiot that claims macs dont get viruses because they dont get the same viruses as windows pcs.
I'm that sort of idiot. I've run three Mac systems (2 laptops and a desktop for a while) over the past 5 years with no resident antivirus protection, and I've had 0 viruses. I've been in cybercafes on at least 4 different continents, hundreds of different WiFi networks, plugged hard drives and memory sticks in from all sorts of people, and never had a problem. I've never recommended antivirus software to any of the many people I've suggested buy a Mac, and none of them have ever come back to me with a messed up machine to sort out - the closest anyone has come was a hard drive failure after about 3 years of use. So, yes, I think "Macs don't get viruses" is a factually correct statement for all practical purposes, at least for the time being.
I'll bite... it's slower than Windows 7 for launching applications, running things like Windows Update and Control Panel - I only know this because my limited use of Win8 has been to help people set up their machines. The 'hover the mouse in the screen corner' thing is totally confusing and unintuitive. Ditto the start screen thing. It actually seems like a step backward to something analogous to the Dos/Win3.1 days - back then most PC users thought of the Win3.1 interface as 'the computer' but sometimes you had to drop down to DOS to fix something, and certain programs (games mostly) were DOS only. Win8 feels like that - there's two competing UIs with completely different metaphors duelling it out on one screen that flips backwards and forwards. It's a bizarre attempt to take the approach that Apple has been using - gradually bringing the touch-based iOS and the desktop-based metaphors together - but Microsoft have just done it in one leap, and the result is terrible. It would be OK if the start screen thing actually brought some major advantage, but it's just a confusing mess that makes it difficult to launch the required application.
"Also since the phone features an active display..." - as opposed to all the phones with inactive displays? Nice slashvertisement, with almost no technical details.
I'm not sure USB has the robustness to work for some professional applications. Look at the mess that USB-RS232 adaptors are - many engineers keep old laptops around just for their proper serial ports. PCIe over Thunderbolt seems to work perfectly. Only time will tell I guess.
Thunderbolt has made internal upgrades unnecessary (or at worst work-roundable). In the sector Apple is targeting, high-end video including broadcast, mobile and studio audio recording, etc., there's a lot of kit that couldn't possibly be connected via USB or even FireWire. Thunderbolt effectively separates the high-end third party hardware from the host machine, which means that in the future artists and producers can walk into a studio with their own machine and software workflow and plug in via Thunderbolt to record and mix. This has the potential to be a major step forward.
Yep, and the creative pros will love it. I've done a bit of work in design and photography offices, and practically all of the Mac Pro towers I've seen have empty drive bays except for the stock boot drive and DVD RW. And the desk and floor is littered with FireWire and USB external drives, audio interfaces, etc.. People want to be able to plug in a new drive without rebooting their machine, and want to be able to take work home on their laptop.
Also the build quality and robustness tends to be a lot better than competitors. I think this has changed in the past 18 months or so as some manufacturers have copied the Apple design style - and added some of their own enhancements - but there are still plenty of creaky plasticky blobs on the market. The price premium compared to high-end Sony, Dell, Asus etc. really isn't that big (and sometimes Apple comes in cheaper) but if you compare tech specs alone than Apple will look pricey.
I consider not releasing several updates to the same computer line in a year to be an advantage. Known hardware platform, not a moving target. Serious issues with the hardware or firmware usually get fixed. Third party software or peripherals that have an issue on a particular model usually get fixed by the developer. Other manufacturers may be happy to leave issues unsolved when it's a problem on one of thirty models on the market that will be replaced in 2 months time. Peripheral developers probably cannot get hold of the particular Dell or Asus model that doesn't work on their device, so it just gets left.
I'm not mocking science, I'm stating fact. Something vague about iron levels that "could possibly make a difference" is no help at all for someone who has no blood blood pressure. If you want to look something up, look up Starling's Law (of the heart) - that's science. The treatment of shock is restoring blood volume/pressure, which vitamin C will not help with.
I'm not ignorant, I'm a medical doctor with years of experience. What you're describing is not treating shock. The treatment of shock is restoring blood volume/pressure, then correcting the underlying cause. Yes there are all sorts of things going on during reperfusion following a hypoxic injury, oxygen free radical damage etc. etc., but that's not shock.
That's hilarious. "Dr. Frederick Klenner wrote 27 papers from the 1940 through 1970 documenting his use of vitamin C (sodium ascorbate) to treat all manner of conditions including shock, viral infections, bacterial infections, and burns." I don't need to read the papers to know that's bollocks. Shock is an emergency medical condition where the blood pressure is insufficient to support vital functions, and without treatment leads to death. No amount of vitamin C will restore the circulating blood pressure/volume whatever the cause - unless you were to give it intravenously in large amounts of water, in which case it would be the water that would be the treatment for volume expansion. Same for burns - the loss of fluid from burns causes shock, and has the same outcome.
I'm not shocked at all. This is just an automated form of hand-optimisation. Plenty of products and algorithms end up in regular use that have been tweaked intuitively (or algorithmically) without really understanding why the tweaking improved it. Plenty of engineering research is about providing models for existing systems to understand why best in class designs work the best. If we held back empirically proven designs until the theory was completely understood we'd never progress with anything.
I think you're failing to appreciate that the video is massively sped up. What you describe as 'suddenly' does indeed look like a cut edit, but was probably a fairly slow upwards movement of the arm as it regained equilibrium after the drop fell. Watch the clock to see.
No. When you login, your session cookie should have an ID unique to that browser session. When you logout, it should cancel that ID at the server side, so even if the cookie persists it would be invalid. It seems like many websites are implementing this functionality by just deleting the session cookie when you logout. That's a problem.
I've been using computers of various kinds since the mid-80s, including Windows from 2.0 up to 8, Atari, Amiga, various Linux distros and most recently Mac OSX. I wouldn't dream of putting a Windows box into production without antivirus software. I've seen serious virus outbreaks on all of the platforms I've used, apart from Linux and OSX. I've never had active (continuous scanning / file protection) antivirus on Linux or OSX and I've never seen a virus infection. In all my years of supporting friends and family and various corporate systems, I've never had to clean off an infected OSX or Linux box. It's just never happened. So maybe I'm deluded or pretentious, but I'll install active antivirus on my Mac once I've seen a single example of a serious infection in the wild. Until then, I'll keep Clam on standby.
So, essentially, you're tickboxing the installation of antivirus software. I'd install ClamXav and tick that box, if it was me. Macs aren't necessarily totally invulnerable, but I've never had active antivirus on my Mac, and I've taken it all over the world and used all sorts of dodgy free WiFi, and never had an issue. The only thing I do is a scan of removable media using Clam if I think it's come from someone who's unlikely to have protection on their Windows box. I put my 3G dongle on my parents' XP laptop (never previously connected to the Internet) and it was infected before I'd had time to download a free antivirus (I forgot that there's a huge difference between being behind a NAT router and plugging in a broadband dongle). Admittedly that was XP, Windows 7 is a lot better, but it is orders of magnitude more likely for unprotected Windows boxes to get infected compared to OSX - and far more likely for infections to spread across corporate networks from Windows boxes.
This may not be a popular opinion, but I'm a big fan of Apple Airport gear. They generally support the latest/fastest standards quite quickly, are easy to configure, have built-in PSUs rather than wall warts, and I've generally found their range to be better than average for consumer WiFi kit. Other than that latest models (which look ridiculous) they're generally neat and look OK in the living room. I've had one Airport Express die on me after 2 years of use, and that was already second hand when I bought it and spent its life behind a pile of hot hifi gear as an Airtunes sink.
The 'text mode DOS crap' is probably a proprietary pathology lab system, and it's likely not DOS at all but a unix running over telnet. Old but super fast and efficient, and not easy to upgrade without replacing expensive lab gear that interfaces with it well. You may also be seeing EMIS, or similar, a GP health informatics system that's again super-fast and reliable. There is an upgrade path to a Windows clients and more modern backend but most areas are following a phased rollout. As for path results - GPs can phone and get the results within 24-48hr, but it's not practical to do for every patient.

Don't worry, I'm sure you can take something to get rid of the 'toxins' from your body if you do take in too many 'chemicals'.
That's hilarious.
