Ask Slashdot: Can Valve's Steam Machines Compete Against the Xbox One and PS4?
Not the OP, but it *can* be that way sometimes.
I dropped $12 on each of 2 titles from DCS:World on a special a few weeks ago. They are normally $40, but Steam was running a big sale to promote a new DCS release.
Anyway, it's a $12 game that probably needs $2500 of hardware to run properly. The graphics are part of it, but the background AI really crushes the CPU as well.

Interactive Nukemap Now In 3D
Defense in depth. Even if we let a terrorist walk into a silo or hangar and take a nuke, he still would never be able to detonate it without the PAL.
Even when there is a wealth of information on the device (like the B-61 http://www.glennsmuseum.com/controller/controller.html ) there is very little chance someone could recover a working nuclear core. There are multiple layers of failsafes which (probably) fire a small charge inside the sealed core to destroy the pre-detonation subsystems.
So, given the option of ordering a fully capable B-61 off of ebay, or stealing an old USSR/Pakistani/Indian nuke, the terrorist would be better off with the second option.
I don't know anything about PALs or failsafes for their nukes.
Hardly Anyone Is Buying 'Smart Guns'
I think you hit on the major problem with (US) gun laws. There are something like 300M+ guns in the USA. Supposedly, those are guns in circulation. i.e. Not sitting in a warehouse or on in a gun shop display case.
It is an easy thing for anyone to obtain a gun illegally for illegal purposes. It is somewhat less easy to obtain a gun legally for legal purposes.
And it's only moderately difficult to modify a legally obtained gun to exceed the parameters that make it legal.
Larger magazines, modified lowers and uppers, mil-dot scopes, and general tweaks can turn any gun into an "assault weapon".
As to the mental stability, the US has a bad track record for dealing with mental issues. Even today, it's hard to get good mental help. You could self-identify today as a potential danger to yourself or to others and it could be 2+ years before you are stable.
And that's for someone who wants to get help. Most don't.
I disagree that we need a gun that can determine if you are mentally compromised. It's just too "sci-fi" to be viable. What we do need is a way to track guns from cradle to grave and hold the registered owners accountable for illegal use.
Jetstream Retrofit Illustrates How Close Modern Planes Are To UAVs
If the plane crashes due to pilot error, then the pilot will never be charged with a crime.
With a UAV, you can immediately test the pilot for drugs/alcohol or any other condition that altered his mental capacity.
If the plane broke, then it sucks to be on the plane. But if the pilot screwed up, then his peers will get to see him charged with manslaughter and dragged through the legal system. Ultimately leaving him a broken shell of a man. Probably in jail.
3 or 4 of those and the other pilots will either become very clever or stop screwing up.

California Bill Would Mandate Open Access To Publicly Funded Research
If the research develops into a marketable product, patents would protect them from other companies.
If the research doesn't pan out, then nothing is lost.
As for fund sharing, if Cali funds 20% of research that goes on to become the next Cisco, Google, etc, then Cali should get 20% of the company stock. Or get a 20% cut of quarterly revenue.
Newegg Defeats Alcatel-Lucent in Third Patent Win This Year
Maybe demand the filing party put a value of the patent into an escrow account. If the value of the patent goes up, just put in more money. After the patent expires, the company gets the money back.
If they file a suit, they can't value the patent at more than is in the escrow account; i.e. MS uses a $10 unlicensed patent to do $100M in business means the company can sue MS for $10.
If they lose, the escrow account goes to the winner.
A Computer-based Smart Rifle With Incredible Accuracy, Now On Sale
I'm not a NRA-type. But I do like to shoot.
Not everyone here loves guns. And those who do love guns have hundreds of reasons why they do.
I keep a shotgun for shooting skeet. I don't care to hunt or eat birds, so it's just a sport for me.
I have a bolt-action rifle for hunting deer. I'm from the Southern USA, and deer season has been in my family since they got off the boat 400+ years ago. I grew up with it and it's something I love to do.
I also have a semi-automatic rifle. One could make an argument for it being an assault rifle, but just because it looks like a military rifle doesn't really mean anything. All semi-automatic rifles work the same. Again, this is a sport rifle for short and medium range shooting. A local gun club hosts a CQB tournament a few times a year and it's fun to run through their "village" and clear targets.
I also have a small, semi-auto pistol. It holds 7/8 rounds of .380. I use it, again, for sport. But I also keep it on me most of the time.
To most of the gun crowd, the 2nd covers any "gun" that fires any "bullet". We have people out here with everything from Civil War cannons to Vietnam-era artillery. Most people in that group agree that a tank would also be acceptable and I have heard that some people do, in fact, have functioning WW2/Vietnam tanks.
The crowd here gets divided when we start talking about bombs and missiles. I fly RC airplanes also, and I do a lot with tri-copters and quad-copters. Most of these control systems aren't much different to 80's style guided missile control systems. But folks around here just think it's going too far to actually implement such a system.
So, we stick with, mostly, a "bullet" fired from a "gun".
Yes, that includes rocket launchers, recoil-less rifles, and RPGs. There are several individuals in the area who are licensed to own fully-automatic weapons and RPGs and the like.
Really, in the US, it's all about what you can afford to license. If there was a "room-killer" on the market, then someone here would probably have a license to own one. I think it's a bit much for anything practical, but I still think it would be cool as hell to shoot one at the range.
A final point. The Second Amendment is a touchy subject. First off, there are (at least) 2 versions that differ in punctuation and capitalization. Second, people argue if it means a Military, a Militia, or just every-day people like me. No one really knows what "arms" are; could be a muzzle-loading smoothbore or could be a tactical nuke in the garage. Third, there is a lot of debate between "well regulated" and "shall not be infringed".
Anyway, it's all a dumb argument anyway. Most guns can't be obtained legally. The ones that can mostly need a State license. Even with the license and legally-obtained gun, you can't carry it in most places.
And that's the way all of the amendments are going. Somewhere, "Congress shall make no law...abridging...the right of the people to peaceably assemble" got turned into "free speech zones".
"The right of the people to be secure against unreasonable searches" turned into "stop-and-pat" and your iPhone doesn't count as "papers" or "effects".
Everything today is "interstate commerce" so the DEA can raid a local pot grower in Colorado.
The Second Amendment should have been a negotiating position to stop that from happening. Not so much of a "I'll shoot you if you try to do this" but more of a "let's see you enforce it" concept. That's probably what it was written for. But it's too late now and people have Idol and Game of Thrones to watch. It ended, not with a bang, but with a flurry of text messages to vote for the next Top Model...
Georgia Tech and Udacity Partner for Online M.S. in Computer Science
That may apply in most cases. However, a degree is now acting as a barrier for entry to jobs people are fully qualified for.
I have seen government contractors hired with a BS in Art History and a CCNA over candidates with HS diploma and a CCNP. It's happening more and more to those of us who just want to ride routers all day. We know the job and lack of a degree should be seen as a good thing. We aren't looking to replace our bosses. We don't want to become managers or team leads or any of that crap. We just want to sit in darkness and work on network stability and optimization.
I'm sure you can find the same thing in CS. People who know how to code, but lack a degree for whatever reason. You'll pass over a candidate who's been programming since age 8 and select a candidate who first heard of programming in his Intro to Computers class.
Ask Slashdot: Do You Trust When a Vendor Tells You To Buy New Parts?
I sometimes look at things like power and water and wonder what could be done with a ground-up redesign.
As for networking, the guy was talking about a 6500 series switch. Anyone buying a 6500 would probably get 2 or 3 and use something like HSRP or the like:
That way, uptime of a single node (probably in the high 90% range) isn't so important. As long as you have one other node operational, then the network isn't aware that anything has gone wrong.
If a water pipe could detect a pressure drop and trigger a set of valves, then you might be able to continue service while only affecting spurs coming off the damaged section.

Meet Drone Shield, an Ambitious Idea For a $70 Drone Detection System
Really, Slashdot? Really?
Those "Â" thingies should have been the symbol for degrees.
Meet Drone Shield, an Ambitious Idea For a $70 Drone Detection System
It wouldn't be that bad.
Have a 360Â servo with a 80Â-90Â servo mounted on it. Directional mic on top of all that.
Arduino/Pi rotates the first servo 1Â then sweeps the second servo. Or vice versa.
Feed that into an algorithm looking for prop noise. Most drone motors will be IC or electric. An IC will be running between 9K~18K RPM. Electric would be running from 7K on the low end to 30K on the high end. Realistically, an electric for drone use would be on the low end of that spectrum; the higher-RPM motors are usually for fast airplane.
Take the RPM and figure a 2-bladed or possibly a 3-bladed prop. Filter bandpass for 15K~55K. Run that through a doppler-shift algorithm and filter out anything moving slower than 20MPH or faster than 200MPH.
Using that, you should get pretty close.
Once you have the location, feed that to another mount with a spotter-scope and webcam. If the image-detection stuff sees something other than sky or clouds, have it snap a few images and SMS/email them to you.
I'm not entirely sure you will get good enough images to identify the specific UAV using servos programmed for Â. The servos usually range from 900-2100ms of pulse width with 1500 being "centered" on the servo. So, you can get it down to 3-steps per Â on a 360Â servo and 13-steps on a 90Â servo if you use straight PWM and good digital servos.
Using Technology To Make Guns Safer
Very few Soldiers, Sailors, Airmen, and Marines will handle a weapon on a daily basis. In a home-station environment, you will have the base security people (maybe 200 people at any one time) actually carrying a loaded weapon. You may have another 100 or so training with dummy/unloaded/blank-modified weapons each week.
The thing that no one ever wants to talk about is that the US Military is just a sample of lower-income Americans. We have thieves, rapists, alcoholics (oh god at the alcoholics), drug addicts, murderers, etc. We keep things locked up because we know we are crazy. Or at least we suspect the next guy is...
Oh, WRT psych evals, there are some, but not nearly enough. Recruiters and basic trainers want to meet quotas. It's in their best interest to pass as many through as possible. Once a (possibly crazy) troop arrives at their post, they are usually kept in-line or hidden by their front-line supervisors. It sometimes seems like the quickest way to get rid of a bad seed is just to wait for their enlistment to end...

A Twisted Clean-Tech Tale: How A123 Wound Up In Bankruptcy
A123 had other problems as well. The batteries they produced were worse than other Lithium batteries in almost every way. Heavier, lower energy density, fewer cycles, etc... Their only advantages was that they could be charged quickly and they kinda resembled (but weren't interchangable) batteries people were used to seeing at the supermarket.
As LiPo batteries evolved, they were able to charge more quickly and their energy density has gone through the roof.

Hosting Provider Automatically Fixes Vulnerabilities In Customers' Websites
>>the developer releases a general security update that applies to everyone, you'd be fine with your host disabling essentially your entire site until you fixed it?
It all depends on the TOS from the host. Maybe the host declares that they disable clients that are contributing to (or may contribute to) network abuse. Unpatched machines will get compromised and become launchpads for attacks on others.
>>And if you're on vacation for a week or two when it happens? What then?
Would you rather come back from vacation to a disabled but uncompromised site, or to a enabled but compromised site? For the first case, you'd need to apply the updates and then restart the server. For the second case, you'd need to scrub the machine, re-install all your software and customizations, then restore your databases and content directories from backup.
>>I rather like the fact that the stuff I run can essentially sustain itself in my absence.
The point is, it can't. You can't secure a box and walk away for days/weeks/months. You need to be actively maintaining your servers.
