I think you might misunderstand how sonar scales in range and intensity. Think of water as being much less like perfectly-transparent air, and more like a light, but continuous fog. After a certain distance, increasing the intensity of sonar will only give you a marginal increase in range, since a certain portion of your signal will end up scattered back at your hydrophones. No matter how 'noisy' they are, there's really absolutely nothing a surface ship can do to ensure they can detect a deep and silent running submarine that really doesn't want to be detected. It's also much easier to design a submarine to mask its active sonar (reflective) signal. Typically, detecting a submarine is more about having better 'eyes' than it does having brighter 'lights'.

To add some data to the current replies to this comment, I suggest you look at the graph here: https://www.census.gov/populat... Between the growth peak in the early 60s of over 2%, we've reduced it to %1.

The problem is: current CPU designs are frequently limited by wire propagation delays. Optical circuits do have somewhat faster propagation than copper (1c vs 0.75c), but increasing the size of components necessarily increases the distance between them. 1 thz = 1 * 10^-12 light seconds, which is 0.3mm, I believe.

This entire thing really only makes sense if you take a look at it in terms of court costs. He was being prosecuted on 517 counts, which makes him, in my mind, much more than just a casual media pirate (as suggested by the summary). If the evidence was pretty much equally clear on each of the 517 movies, it probably saved a lot of court time and money to pin all of the substantial penalties on a single count and then suspend the rest of them. The downside for the court is that a huge amount of publicity it generated because of the "$650,000 for one movie" angle, whereas this might have caused less outrage if it had been a $1250 fine per movie, even if the total had been the same. If somebody else has another explanation as to why they would choose this bizarrely lopsided penalty, I'd like to hear it. Okay, scratch all of that. I read the related article, http://torrentfreak.com/largest-ever-bittorrent-tracker-movie-uploader-trial-concludes-131120/ and it says that only a single producer seeked damages. What an asshole, destroying someone's life for the sake of a 25 year old shitty horror movie.

PPD files are platform-independent which always smelled sweet to me when I was using a mac or linux. Other printers I've had to throw in the trash because the driver didn't make the jump from XP to Win7. I maintain a VMWare VM with XP just to print on a not-so-old commercial-quality thermal CD printer.

Take a look at the conductive "pins" (strips) on the inside of a USB connector (cable side). See how they're not all the same length? When you're pulling out the plug, the shorter pins (that don't carry power, only data) lose contact first, triggering the hub end to cut off the power pins before the power pins break contact. The reverse happens when you plug it in. No power from the hub until the data pins connect. Thus, no arcing. Any connector designed to be hot-swappable has this type of design.

Democracy and rights are not necessarily hand in hand. The only right a democratic society needs to have is to have fair voting for laws and/or a government. Democratic societies knowingly can and often DO vote away their own rights, all the time. Democratic does not mean free or just.

While I favour Java somewhat over .NET/C# and this 'test' supports my favourite, I just want to point out that this test is entirely useless. To fall back on the well-worn car analogies, this is like testing which car starts up faster. Who cares, if you never go anywhere? So, the Java server takes a quarter millisecond to processes an empty request compared to one millisecond. Who cares, if you're not actually processing anything in the request? The difference would be lost in the noise of any real-world test.

Security Expert Says Java Vulnerability Could Take Years To Fix, Despite Patch 320

Posted by samzenpus
from the long-road-coming dept.
An anonymous reader writes "After the Department of Homeland Security's US-CERT warned users to disable Java to stop hackers from taking control of users' machines, Oracle issued an emergency patch on Sunday. However, HD Moore, chief security officer of Rapid7, said it could take two years for Oracle to fix all the security flaws in the version of Java used to surf the web; that timeframe doesn't count any additional Java exploits discovered in the future. 'The safest thing to do at this point is just assume that Java is always going to be vulnerable,' Moore said."
