Comment Re:Guaranteed to put stress on any car? As if. (Score 1) 54

Having driven on the autobahn it's probably the easiest place to try something like this. Everyone there already moves like robots. It's like some lawmakers figured out an "API" for how to communicate between vehicles.

I want to see it done around Chicago where it's "surprise, I'm coming into your lane".

Or Boston, where the only way to change lanes is to pretend that you're driving drunk, so that everyone will back off!

Comment Re:Actually ... (Score 4, Informative) 35

Pretty much this. I've been confused as to why this was an issue ever since it was. The navy *HATES* to go active on sonar, as it instantly gives away your position at a distance far longer than you'll get any information back. Active sonar is reserved for localizing a target that's close-in immediately before firing a torpedo, and often not even then. They also have a special high-frequency sonar specifically for under-ice operations. But for general searching in the open ocean? It's all passive. (My dad was a sonar guy almost his entire 20; starting out in GUPPYs all the way up through 688s.)

If you read the article, (I know, I know...) you would have learned that the Navy uses active sonar and explosives during training exercises to practice combat tactics.

(You probably could have also figured this out yourself since you appear to be a pro at sonar.)

So yes, you would use passive detection techniques hunting another sub, and then switch to active sonar just before firing a simulated torpedo at a simulated target. This is why they are only limiting their use near Hawaii and the US coast... because we generally don't do a lot of sub attacks in that region. However, when the Navy is training, they generally like to do it in a safe area that will not alarm other countries and where they can respond to accidents quickly... which is why they were doing it near the US coast.

Smart motivated kids like this become terrorists when you alienate them from your society for doing something they are proud of... like showing off their cool, benign project.

I love the police chief's refusal to admit any mistake as well:
'“We live in an age where you can’t take things like that to school,” he said. “Of course we’ve seen across our country horrific things happen, so we have to err on the side of caution.”'

Well heck, let's just stop going to school.


Comment Re:Never reuse passwords (Score 1) 146

This kind of stuff is the reason I never re-use passwords across services. All my passwords are randomly generated and stored by KeePass. Sure, it's a little less convenient to have to unlock the password safe in order to get into services, rather than just type in something you've already memorized. But, it's the only way to be sure that having your password compromised on one service won't compromise an account on another service. Even if the service isn't externally compromised, there's probably a lot of systems out there where employees (DB administrators, programmers) can gain access to the passwords from various methods such as logs or unaudited code.

I think this whole password fiasco has gotten super fucking complicated for a normal human being.

When you need a password manager application to tell you what to type into the computer, we might as well all just switch to a tokencard system.

Or better yet, write you passwords down on a card in you wallet. Write you login names down on your password-protected phone. Problem solved. Go ahead and try to hack that system remotely.

I'm not using an app right now. It's extremely easy for me to just go to a competing site if you don't want donations or paywalls.

There are very few sites that will publish content out of the goodness of their hearts. If they can't get paid through advertising, then it's apps or paywalls or something but not free.

Don't get me wrong; I use adblock and never see ads. So I guess I'm a hyopcrite. But if online advertising can't unltimately make money somehow we're gonna have a very different web on our hands.

Like it would really matter if 90% of the advertisement-supported web disappeared.

Where would we be?

Back to the newsgroups that we had originally... which arguably was better than the highly predatory environment that it's evolved into today.

It's better to be alive and hated by all motorists than it is to be dead.

But it's even better to be alive and liked by all motorists!

A lot of the cyclist hate is driven by cyclists and motorists driving around with a mentality they are at war with each other. If everyone just treated the other as they would prefer to be treated, things would go a lot smoother. Instead, things escalate because of mistakes on both sides:

Tailgating a cyclist in your pickup just to be a dick? Fail. Cycling uphill in the middle of a 55 MPH lane at 15 mph just to be a dick? Fail.

Not passing a cyclist with enough space to show him who's boss? Fail. Not moving over to let a motorist by who has been stuck behind you for a mile? Fail.

You get my point...? It goes both ways. When you get locked in to one mentality, you just alienate others against your cause.

We could also easily extend this to pedestrians. Sadly, there's been a general loss of respect and politeness in public amongst humans over the past 20 years.

The F-35 IS expensive _per_unit_. The A-10 does one job, and there are several other aircraft that do different jobs. So the A-10 sits on the ground while there is air-to-air taking place, waiting while another aircraft handles that. IF the F-35 does four different roles, replacing four different types of aircraft, that cuts the effective cost by 75%. It wouldn't be parked on the tarmac waiting for a time when CAS in needed with uncontested skies. It could, supposedly, when the skies while also bombing enemy airfields , then do close air support.

Let's see how it actually does in testing before we declare the result.

The thing is, the US has never fought a war where it did not need close air support. Ever.

So having a dedicated aircraft for this role seems like a really good idea. Especially when it is 1/8th the projected cost of the F-35.

Beyond that, it's an arms race. You can't hold someone responsible for being hacked, unless they've demonstrated that they didn't even try to avoid it. Reasonable preventative measures.

That's not really true.

Reasonable preventative measures include not saving unnecessary information like (1) credit cards, (2) home addresses, (3) full names for a site that only exists for a form of social networking.

Extreme preventative measures include not keeping any electronic transaction records, instead only saving printouts of data.

Both approaches would be expected for an online business that makes its profit from anonymity.

Why is dogfight a parameter in assessing 5th generation plane?
It's like saying my car sucks because I can't use a crank to start the engine like the old cars could.

A fighter's raison d'etre is dogfighting.

With the development of cruise missiles, drones, and long-standoff munitions, fighters are less relevant for air-to-ground use today when going up against an adversary with limited capability. But the US needs fighters to be able to maintain air superiority in any situation. Just because all of the US's latest mid-east engagements have not involved an air superiority struggle, doesn't mean that a future conflict will not... especially if it involves a Russian or Chinese supplied country with actual competitive weaponry.

You're also missing the main point of these weapons, which is that their implied threat is their most effective capability. If the fighter is known to be superior to all others, countries will prefer not to engage it or will waste lots of resources developing their own similarly capable fighters.

I'm not a Republican and frankly I thought they were just muckraking till now, however if this information is correct then she is likely guilty of violating 18 U.S. Code 798 - Disclosure of classified information (if not other laws and oaths as well) and should be tried and punished appropriately. Since she's one of the elite it will likely get swept under the rug instead.

It is muckraking.

The information was not deemed classified until long after the emails were sent. This happens a lot in government emails as situations evolve and when it does, recommended procedure is to clean up what you can and not discuss the issue any further on the low side. This is a dangerous game that the Republicans are playing because politicians on both sides likely have (retroactively) classified information that was once emailed as unclassified. (You wouldn't, for example, post new releases saying that her emails had classified email... like is currently happening!) What server is was stored on is irrelevant if it was emailed over an open network. It's not like government servers are specially protected in a magical way anyway... look at the recent Office of Personnel Management breech.

Frankly, if you want to be mad at the Democrats, be mad at Obama instead. He likely disclosed a spectacular amount of classified information on the Bin Laden raid, both in terms of the actual raid specifics, seal team operation protocols, and CIA surveillance capabilities. Then he used presidential discretion to justify and declassify it.

It's interesting that all of the well-publicized national security breeches seem happen just before presidential elections!
