There's a bit more information about why "Dirac electrons" (electrons behaving relativistically instead of classically) are important for quantum computing here:
Yes, people use ionization trails to reflect their radio transmissions, but in TFA they discount this as the source of the emissions:
Meteor trails are known to reflect radio waves and indeed this has been one way of spotting them in the past.
But Obenberger and co reject this idea for a number of reasons. First, human radio transmissions are usually polarised and so any reflections ought to be polarised as well. The team found no evidence of this.
At the same time, human radio transmissions have easily identifiable spectra but the team found no evidence of this either in the data from the Long Wavelength Array.
"It is therefore our conclusion that ïreball trails radiate at low frequencies," they say.
The NASA's Solar Dynamics Observatory (SDO) will be providing near real-time images/movies at http://cometison.gsfc.nasa.gov/ on Nov 28 between 12:45 pm and 1:00 pm ET (1745 - 1900 UT)
Can hydrogen masers amplify any frequency? I admit I know next to nothing about them, but I was under the impression they could only amplify at the resonant frequency of hydrogen (e.g. see http://tf.nist.gov/general/enc-h.htm)?
I would agree that torrents are usually faster. But in this case, I doubt it. Did you actually try downloading from any of those links? I just did, and it stayed steady at 2.7MB/s for the 2 minutes during which I ran it (I cancelled it because I already have a copy). Chrome estimated 17 minutes (total) to finish (for a ~3.1 GB file).
Not many torrents are going to be that fast, I think. You also don't have to worry about malware in the image, or BS copyright violation notices.
Let's say that's true (i.e. font cache is corrupted on crash).
1) Sounds like a bug to me. File a bug report? (after gathering evidence, of course)
2) Possible workaround: Make a known-good copy of the font cache (on Windows it's %APPDATA%\vlc, I believe). Restore it after a VLC crash (before launching VLC again)
OK, that's fair, I wasn't clear. Obviously the guards should be able to operate the functions required for their job.
I was trying to say that you can't assume malicious software doesn't exist on your network; i.e. you cannot leave out basic security controls just because the thing is on a ostensibly private network. No software should be able to open a door by, say, sending a simple ASCII string on the right port (I've seen that kind of stupid crap in other software). Why not specify that you need two-factor authentication to open a door? That would at least prevent attacks any kindergartner could perform.
The security should be [...] an air gap enforced by a physical barrier [...] [but this is] regularly broken by people disregarding policy and carrying in USB memory sticks.
You admit the fatal flaw, but still think physical security is enough? Even when it appears that all it takes to defeat your "security" is one retarded, or corrupt, security guard?
You might as well cover your ears and scream "LA LA LA I CAN'T HEAR YOU". Obviously these PLCs need to be connected to a network of some kind to be useful. But even when that network is physically secure, those PLCs and their associated IT systems need to be secure against known attacks.
I just downloaded nmap and vlc. Both files were identical to what I got from the source.
Actually,it looks like cnet redirected me to the nmap.org download link (http://nmap.org/dist/nmap-5.51-setup.exe) using a 'META HTTP-EQUIV="Refresh"...'. VLC was still from cnet.com.
I'm not logged in; I wonder if I have a cookie that prevents the wrapper -- or if download.com changed something.
Also, I'm using NoScript and cnet/download.com is not allowed. Perhaps this turns off the wrapper too.
Not only can you retrieve the password for any user on the system but you can also reset their password without having to know what it was.
According to the FTFA, you can only reset passwords for the currently logged in user. It doesn't say anything about resetting other user's passwords:
It appears Directory Services in Lion no longer requires authentication when requesting a password change for the current user [emphasis mine]
Still not good, but not nearly as bad as you suggest. Now, all that said, I don't have a Lion system on which to test resetting another using password using dscl. I can only hope it doesn't work.

That link you posted is how to make a blank disk image. It does *not* tell you how to make a bootable image from which you can (re)/install the OS.
When your hard drive fails, how are you going to install Lion on that brand-new replacement hard drive? It would be nice to have an external drive or optical media from which to boot, wouldn't it?
I've tried two separate apps -- "WebMessenger Message Alerts" and "AlertMatrix Pro". Tech support for both companies told me the same thing -- if you encrypt the phone, their apps cannot read the emails.
Blackberries can be securely encrypted, but it caused me a unforeseen problem.
I use my blackberry to filter incoming emails and alert me based on the message contents (or subject, sender, time of day, etc.) You can't do that with the default email program -- you have to get a third-party app.
Unfortunately, if you encrypt the phone, the third-party app can't read the incoming emails anymore. It seems to be a platform limitation. (If someone can prove me wrong, please do so!) I *want* to encrypt my blackberry, but it would then become basically useless to me.
I have a password on it, of course, but that's not nearly as good as using device encryption.

Yes, you're right, I didn't read the table carefully!
I don't know what you're looking at, but it's the wrong patch. The patch in question is MS14-068, and it affects every system listed in summary.

Why torrent an ISO when you can download official ISOs from Microsoft?

I just tried to buy a VPS and for every offering I get the error "We are currently out of stock on this item...". Too many clients?

45 comments, perhaps 3 of which that aren't jokes or AC trolls. /. used to be a place where science could be discussed intelligently...
I guess I'll spend my time at reddit r/askscience instead!

A decent story from NPR (WARNING: contains Ira Flatow) on what U.S. providers are calling "4G" even though they don't meet the ITU definition: http://www.npr.org/2011/01/14/132934022/what-does-4g-really-mean-anyway
If those provide very basic filter options work for you, great!
I need more features in my filters (multiple criteria, different alert sytles based on message content, etc.).
I've tried two separate apps -- "WebMessenger Message Alerts" and "AlertMatrix Pro". Tech support for both companies told me the same thing -- if you encrypt the phone, their apps cannot read the emails.
