Ask Slashdot: How Do You Manage Your Passwords?

scheme Re:Air Gapped Box (445 comments)

Completely off topic: what would be the best way to physically disable the wifi capability of a device. Obviously you can disable in software, but I'm the paranoid sort, and would love a way of knowing that my IP web cam is not gonna be doing anything with that wifi antenna. Thinking maybe some kind of terminator or some other way of "absorbing" the signals.

Find and remove the antenna for wifi. If that's not possible, make an impromptu faraday cage around the body of the camera. It won't completely block the signals but it should reduce it significantly.

FDA Tells Google-Backed 23andMe To Halt DNA Test Service

scheme Re:Fuck these government pricks (371 comments)

I am a 23andme member and my genetic test showed that I am sensitive to warfarin. That's something I never knew before. If I ever get into a situation where that drug is used, having informed the doctor of this potential problem just might have saved my life. There is no possibility that this information could result in any harm, because if the doctor gives a lower than normal dose and it's not effective, he can simply give more.

What if the test is incorrect? You claim that there's no risk because the doctor can just titrate the dosage up, but if you have a time sensitive condition then the extra time required to adjust the dosage up could result in irreparable harm to your health. E.g. you get a stroke or thrombosis while the dosage is being adjusted.

As Hurricane Season Looms, It's Disaster-Preparedness Time

scheme WTF? (117 comments)

Hurricane season has been going on for a few months now. Why the hell would a data center or organization review their hurricane/storm related disaster checklists now instead of, oh, you know, before hurricane season? Any organization complacent and negligent enough to wait till the end of the hurricane season to review/correct their checklists probably isn't going to actually care about the checklist anyway.

Syria: a Defining Moment For Chemical Weapons?

scheme That's BS (454 comments)

When war is excused, for any reason, it is a sign that civilization is failing. It's the exact same thing as college sports.

...

When the only way to resolve matters is with bombs, then we're all going to die in a war. I don't understand why the US doesn't just impose sanctions on Syria. Seriously, wtf are they going to do, bomb the place(s) that are producing chemical weapons? I guess that's one thing they could do, but how about simply go in and try to talk it out? Or stay the hell out of the way? If the US puts itself into their war, then won't that make more people hate the US, and in turn, create more reasons for terrorists to try to fuck with the American people?

So you're saying that everyone should have stayed the hell out of the way in Rwanda when the Hutus decided that the Tutsis population didn't need to keep living. I think that the shame then was that the UN and international community waited 100 days and let over a million Tutsis people die before intervening. If you're going to call the intervention and subsequent war against the Hutu government a sign that the civilation is failing then you have no sense of decency. An analogous situation arises in the Bosnian civil war.

Economic sanctions don't always work and for some countries aren't effective. It's not going to hurt Syria if they don't buy anything from the US or can get what they need from the black market. Unless of course, you're suggesting that we blockade all commerce to Syria and slowly let the population starve.

Container Ship Breaks In Two, Sinks

scheme Re:So do those containers sink or float? (361 comments)

If they are airtight, maybe some could float? If you bump into one of those 7000 while you are out jet skiing, can you take it home as yours? Finders keepers? Or does the shipping company still own the containers?

They do float for a while, even worse, they can float a few feet before the surface which may result in the boat you're on suddenly running into a very heavy metal container in the middle of the ocean. Fun times.

Container Ship Breaks In Two, Sinks

scheme Re:Declared underweight? (361 comments)

Even if that was what happened, that has nothing to do with overloading. Verifying container weight wouldn't solve the problem.

BTW, did you even look at the pictures?

What? If you verified the container weight, you could make sure that your loading distribution is within x% of your planned distribution preventing weird moments causing undue stresses on the ship.

Next-Gen Gorilla Glass: Smartphones Could Have Antibacterial, Anti-Glare Displays

scheme Re:Phobia... (175 comments)

Wouldn't door knobs, faucet and toilet knobs, stair railings and cart handles be a much higher priority?

If you have germaphobic tendencies, think of this the next time you're in a public bathroom: what is the last thing touched before you wash your hands and the first thing touched after you wash your hands?

Brought to you by the Ruining Daily Activities Program...

Screw, that. It turns out that keyboards have more germs than toilets.

Next-Gen Gorilla Glass: Smartphones Could Have Antibacterial, Anti-Glare Displays

scheme Re:How about (175 comments)

If you want a surface that is scratch resistant, you need to get something that's really hard. If you want something that is shatterproof, you want something that is soft or can flex enough to absorb impacts. You'll need a breakthrough to find something that's both. Manufacturers went the scratch-proof way because it's more likely that your phone would be in your pocket with keys, coins, etc. than being regularly dropped.

Next-Gen Gorilla Glass: Smartphones Could Have Antibacterial, Anti-Glare Displays

scheme Re:How about (175 comments)

The use of an ever-so-slightly curved face on the Galaxy Nexus seemed to bring some anti-shatter success. I wonder why that wasn't further explored in any subsequent models.

Making and getting the curved glass surface right was apparently a pain in the ass.

Ask Slashdot: Exploiting 'Engineering And ...' On a Resume?

scheme Re:Defense Contractors (207 comments)

First of all make sure you apply to the big defense contractors. Lockheed Martin especially likes to hire ex-military. Given that you were a jet pilot, I mean that's pretty damn impressive. Emphasize how you can work with complicated systems. Flying a jet isn't easy. Were you a leader in the military? Emphasize leadership skills. I assume flying combat missions takes communication skills too. Emphasize those.

I believe all pilots are officers so he was a leader in the military.

Banker Offers $1M To Solve Beal Conjecture

scheme Re:What's in it for him? (216 comments)

Well, the banker is the Beal in the name of the conjecture so he's directly involved since he stumbled across this while looking at solutions to a more general version of the equation in fermat's last theorem. He's rich, has extra cash, and probably is curious to know either way about his conjecture.

iTunes: Still Slowing Down Windows PCs After All These Years

scheme Re:And...? (519 comments)

How is this news? Oh right, it's not - It says so right in the title.

Can I start submitting stories about how h.264 conversion consumes CPU cycles? I mean, it theoretically doesn't need to - I can fathom a zero-work scenario where it just happens. I can even give a play-by-play about how I open my system monitor to verify performance. Amazing stuff!

Honestly. How did this BS make it to the frontpage.

Sure, I'd love to hear how h.264 conversion doesn't theoretically need cpu cycles. How does the zero-work scenario function? The problem with itunes is that it uses a significant and noticeable amount of cpu when it shouldn't and apparently has been doing so for years with users complaining about this left and right.

Does Antimatter Fall Up?

scheme Re:Maybe our universe is a 'matter bubble' (255 comments)

Then we should see a very bright border as matter and anti-matter annihilate on the edges. As far as I know, that doesn't exist so being a bubble of matter in anti-matter doesn't seem likely.

Hijacking Airplanes With an Android Phone

scheme Re:Remote control 101 Re:I call BS (131 comments)

I am going to call BS on this one. These are indication systems. Think of smashing your speedometer and turning the needle with pliers and expecting the car to go faster.

Remote control is not a direct connect. It follows communications paths, and the information and control path apparently connects through the internet, both through the display and control path.

No one needs direct connection within the airplane -- all ya need to do is control it through the internet, at any receiver path, and any transmitting path. with additional directional antenna paths.

Can't do it from onboard, has to be from a remote site, and will involve additional receiver and transmit packages, not included on the android phone. (don't even have to be near the android used for control).

Are you in sales or marketing by any chance? Because this is the sport of keyboard heavy information free verbiage that typically comes from them.

Crazy Eric Schmidt, His Yacht Prices Are Insaaane!

scheme Re:ugly (179 comments)

That;s a lovely boat. It's a work boat, not a pagoda on a glass brick like some other luxury yachts we've dissected. It might even weather a real storm in a real ocean as opposed to sinking at the dock as soon as the tide turned.

He should donate to a real oceanography group, Scripps, Texas A&M, hell, NOAA could probably use it.

Or, if he will simply transfer the title to me, I'll pay for the moorage and start buying lottery tickets to put fuel in the thing. Maybe a kickstarter project....

Given that it was used in oceanographic research cruises in the Antarctic, I think it's probably already weathered some real storms and been through some pretty crazy seas before. The specs on the thing make it look like it'd be a nice working vessel.

IBM Designing Superman Servers For World's Largest Telescope

scheme Re:26 petabytes? (67 comments)

Is internet traffic really only 26 Petabytes a month, while that is a big number it sounds awefully low to me as the place I work does 15 Terabytes a month and they are little more than a miniscule pimple on face of the internet.

That's just wrong. Open Science Grid transfers about 1.4PB a day and I seriously doubt OSG uses a significant fraction of the bandwidth on the net.

New Imaging Sheds Light On Basic Building Blocks of Life

scheme Re:Wait a second... (49 comments)

The contaimination levels are explained in this article. I believe aids and influenza are both BSL-2. I think the levels are based on ease of infection, potential severity, and treatments. AIDS is pretty hard to get outside of fluid transmission but it's pretty severe once you get it . OTOH, influenza A is fairly easily transmitted but most people recover (~30,000 die each year from it in the US).

Walk or Run: Are We Built To Be Lazy?

scheme Re:Looking around me... (189 comments)

I'm pretty sure we're all meant to run a LOT more than we do - and we've forced ourselves to stop due to social pressure.

Hate to break it to you... but we're not. Humans run worse than just about every vaguely similar sized animal on the planet. The reason that we are the way we are is most definitely not because we can run fast.

It's up to you whether you run - I hate running personally, but love swimming, football (yes I know that involves running), rowing, tennis (see before). My knees are not cut out for long distances.

Actually, if you look at the stats, people tend to be the most efficient runners on the planet (with kangaroos coming in second). Although quadrupeds can run faster, they tire out much more quickly as well as overheat. The end result is that over longer distances (45+ km), humans are pretty competitive with animals such as horses. There's actually a hunting technique that's been used called exhaustion hunting, where people chased a deer or whatever until it collapsed from exhaustion and then ran up to it and killed it. It works because running on two legs is more efficient than running on 4 legs and because people have a few adaptations (e.g. hairless skin, etc.) that allow them to get rid of heat more easily.

Students Calculate What Hyperspace Travel Would Actually Look Like

scheme Newtonian Gravity too (234 comments)

Newton's law of gravity is broken as well. The thing is that although it's inaccurate and broken, it's a really easy approximation to how gravity works that gets you results that work well enough that people still use it for most situations. SR is similar, it doesn't work in non-inertial frames but with inertial frames, it's good enough in most situations and a lot easier to use than GR.

Crucial M500 SSD Promises 960GB For $600

scheme Re:SSD replacements? (144 comments)

No it decreases reliability by half. If any one of the drives fail, you cannot recover data off the other.

It's more than that. If p is the probability that one of the drives will fail in a given timespan, the chances of your array staying up is 1-(2*p + p^2) . The problem is that you need to consider the possibility of both drives failing so the probability of the array going down is p+p+p^2 so things are worse than just having two independent drives.
