Submission + - How to Build Enterprise Wireless Network over PoE? (fs.com)

fiberopticalcom writes: In enterprise, the requirement of WiFi connection is very essential to accommodate today’s business trend – connecting mobile devices to business or corporate networks including Android, iOS and Windows based mobile phone devices. Mobile devices are getting smarter in supporting the business tools including messages, accessing business files, business class security and still more. There are many methods to build enterprise wireless network, among the PoE (Power over Ethernet) wireless network is considered to be the most popular deployment methods.

Submission + - Heat-activated penile implant might restore sexual function

randomErr writes: Brian Leis, from Southern Illinois University, hoping that a heat-activated memory metal called Nitinol (NiTi) will create a better implant for men with erectile dysfunction. Nitinol is a nickel-titanium alloy which remains flaccid at body temperature but can "remember" an expanded shape and return to that shape when heated. The heat source will be a remote-control device that can be waved over the penis, using induction to heat the NiTi a few degrees above body temperature and ratcheting open the alloy prosthesis to expand the penis in length and girth. "We're hoping that, with a better device, a better patient experience, and a simpler surgery, more urologists would perform this operation, and more patients would want to try the device," Le sa

Submission + - Satellite spots massive object hidden under the frozen wastes of Antarctica (thesun.co.uk) 5

schwit1 writes: SCIENTISTS believe a massive object which could change our understanding of history is hidden beneath the Antarctic ice.

The huge and mysterious “anomaly” is thought to be lurking beneath the frozen wastes of an area called Wilkes Land. It stretches for a distance of 151 miles across and has a maximum depth of about 848 metres. This “Wilkes Land gravity anomaly” was first uncovered in 2006, when NASA satellites spotted gravitational changes which indicated the presence of a huge object sitting in the middle of a 300 mile wide impact crater.

Comment Re:CVS or Subversion (Score 1) 325

Another vote for SVN (Subversion) here. You can spin up an SVN server on Ubuntu in about 30 minutes. Then add the web front end in another 10. A WEALTH of clients in both GUI and non-GUI for all platforms. And it is lightweight on the client side. (Only has a single version locally) The code is very mature, and you do not have to worry about patches often, and it is just easy to use.

However, it is missing some things on your "Things that would be great" list, but not many. Not at all with some of the larg ammount of tools and addons built for SVN.

If it doesn't REALLY need to be on a Linux system, you can get Apache+SVN up and running in about a minute with VisualSVN Server. Domain integration, GUI for fine grained access controls, and it's all brain-dead simple and free.

CollabNet seems to have something similar called Subversion Edge for multiple platforms, but I haven't used it and they were late to the game.

I wouldn't recommend anyone roll their own svn+apache system. It's not worth even ten minutes of your time when those tested, out-of-os-distro stacks are available free.

Comment Re:Why do they need ANY info? (Score 1) 423

Ok, why do they even need to know if the car is in MOTION at all just to play music??

All of my car stereos so far, have never had to have any connection to car info to play my songs as I barrel down the road. On custom installs, I've never hooked to any of the car data, etc.

Why would an entertainment system need to know any of that information at all?

My car stereo from 2005 increases the volume as my speed increases, and that feature probably goes way back.

Then there's maybe the option to suppress notifications while you're driving some people might like.

Who's software is responsible for displaying the backup camera view, and what draws all the overlay info on that screen? The infotainment system right?

I don't really get when people say that software isn't compatible with touch. All a mouse does is points and clicks, which you can do with your finger. I use a remote desktop app called 'Jump' on Android and it works on a regular desktop just fine.

I hope your version of hell, should you get there, is eternally manipulating a scrollbar widget by finger in a tiny display which pans around in an infinitely large display. If you move off the track half an inch, it snaps back to to the bottom where a little note says "touch compatible".

Comment Re:Windows uses a unix file hierarchy (Score 1) 54

I never realized that Windows uses a unix-like file hierarchy.

According to the article, drive C: is actually a symbolic link to \Device\HarddiskVolume4, COM3 is \Device\Serial0 and so on.

I'm surprised, frankly. My exposure to Windows is pretty much nil (and I like it that way) but I always assumed that the the C: drive and COM: stuff was a completely different way of accessing the devices and whatnot than what Unix uses. Apparently, it's actually quite similar once you get under the hood.

Learn something new every day....

The NT object manager, doesn't that have more in common with VMS than UNIX?
Linux's sysfs is similar, in ways, but neither of these are unix-like unless... um, all hierarchies of objects are unix-like?

If you're sincerely interested in OS internals, you should expose yourself to other systems without prejudice. Otherwise, everything "tastes like chicken".

Comment Re:Why? What advantages does this have over ZFS? (Score 1) 132

You won't be hooking 4TB of storage to that 4GB server and running ZFS under load

Modern servers, even desktops have so much extra capacity it's not even worth hesitating to turn on all sorts of background services these days. Configuration management, integrity checking, backups, compression, encryption, software dedup, we don't think twice about this stuff anymore.

High capacity, high load, small working set size, minuscule physical memory, and a local filesystem... where is that combo in the real world?

A real system where ZFS is too "bloated" to use would mean I'd be afraid to install a backup agent or run Puppet on it. This all seems very contrived.

Comment Re:ansible (Score 1) 43

No. That's not how entanglement works. A better way of thinking about entanglement is imagining two fair coins that can be any distance apart and the first time you flip them, you are guaranteed that they'll either both be heads or both be tails. This isn't a perfect description, but this is close enough

Perhaps even better (per the analogy to particle-spins) is to imagine that one coin is guaranteed to be in the opposite state of the other, i.e., if one is heads, the other is tails.

Another important point is that you cannot control the outcome of the observation: you can't make your coin produce a head or tail, you can only flip it and see what happens. If your coin shows say, a head, then you know immediately that the other is a tail, no matter how far away it is -- but you can't control the outcome, so you can't use the observation to send a faster-than-light signal.

It's like mashing two TINY potatoes together and setting the remains aside. They are now entangled. When you observe one, you can infer the state of the other if neither had interacted with any potatoes in the meantime because if your potato is missing a hunk, it's probably stuck to the other one. We observe these tiny potatoes by throwing other little vegetables at them and observing the results, thus disentangling them in the process, because now you have broccoli guts all over.

It's "spooky" because you can separate the potatoes by any distance, and when you measure one, you know something about the other one even if it was eleven lightyears away. In other words, the potatoes are in a superposition of states until you measure them, and once you do, the other potato picks the opposite state, because I think Copenhagen interpretation of QM is absolute bulls*t.

It's gotten way better with 'connected-standby' on 8/10. Microsoft IMO though solved the suspend/resume problem by just making boot ridiculously fast in 8.1 and even faster in 10. The surface tablets I've had have never glitched out a single time and it does a really good job of going into hibernate, writing to disk and shutting down completely after a specified duration. Almost every time I resume a Surface it has already gone into full hibernation/shutdown. In fact I don't think after 8 you could actually shut down your computer instead of hibernate without going to a hidden shutdown option, it's just the default option.

They should stop the charade and call it Windows OS X already...

Comment Re:string.. (Score 1) 176

I wonder how many people would walk
up to a stranger, grab their camera and throw it hard to the pavement - its much the same thing really.

I disagree. Its not the same thing at all, because any scenario involving a stranger involves a stranger.

It doesn't escalate straight to throwing the camera to the pavement because I have other options to engage the stranger.

But a drone 10 feet up? What am I supposed to do? Ask it politely to leave? I can do that to the stranger. I can also gauge his 'creepiness / intrusiveness' factor much easier as well; as well as how receptive he is to the fact that I'm not happy he's there, etc.

I agree with your reasoning.

I don't see why it's any different than someone tossing any object onto my yard, remote control or not, on the ground, in the air, in a tree, on my roof, all the same. I believe I have the right to physically move it if I don't want it there. No need to damage it more than necessary to move it, but I don't need to leave it there, and it's not like we can call for a professional tow as we would for a car. Something as expensive as a drone is going right to the police department for the owner to pick up.

If the owner wants to lower the chance of his expensive flying toy getting damaged, he would be flying it low and slow enough for someone to safely pick up. Um... as with anything else found in my yard, it was like that when I found it, as a general rule.

The mosaic theory wikipedia page (on the intelligence strategy) from the summary is not even REMOTELY close to the Fourth Amendment mosaic theory from the article, that the opinion relies on: http://repository.law.umich.ed...

I've seen this first-hand. A guy locally was going around with an up-skirt camera rig in his duffle-bag. I saw what was going on and alerted security, they called the cops... They said it was a public place with "no reasonable expectation of privacy" so as much as they wanted to get him, they didn't think it would hold. (The guy was long-gone by the time the cops arrived)

How could you NOT accidentally step on and kick a knee high camera that close? I'm really surprised nobody accidentally destroyed it and had to exchange information with the guy, you know, to replace it, or something.
