Comment Re:Once again no editing (Score 2) 37

Well, being Slashdot, people will use the initialism in their comments, and others will ask what it means, so having it spelled out isn't a problem. It's much better than the summaries that use an initialism without explaining it. There have been many that did that, often with much more obscure references.

Of course, the real answer is that in most cases the summaries are cut-and-paste copies from the article.

Comment Re:Geared for passing tests... Thats todays societ (Score 1) 416

Yes, I was thinking the same thing. If you focus on the testing, the result is something (or someone) that is good at taking tests. This is particularly bad when there are aspects of what you're doing that aren't (or can't be) tested.

In the case of emissions, part of the issue is that the tests aren't realistic. It sounds like the government should require a validation test where they monitor the emissions while the car is actually being driven. The manufacturer would pay for the testing, and the government would spot-test a few cars of each model every year, in addition to the regular emissions testing.

Or leave the system as it is, but then pay bounties funded by fines for anyone that proves the emissions of a given car model don't live up to the standard in real-world situations.

Comment ReplayTV all over again (Score 1) 85

I remember when TiVo first came out. ReplayTV came out at almost the same time. ReplayTV was more expensive, but had lifetime listings included. Ultimately that proved to be a bad marketing decision, and would have probably led to the company's demise if the lawsuits hadn't effectively killed it first.

ReplayTV had already upset the networks with it's 30-second skip button, but the feature that led to major lawsuits was the automatic commercial skip.

It's a shame they didn't both survive and compete on features. I wonder what TiVo would have come up with by now with more competitive pressure?

Comment Re:No Osborne Effect! (Score 1) 398

Nonsense. Did you actually listen to the interview? It's in the context of hypermilers--setting the record for the longest possible drive on one charge--not real or rated range under normal conditions.

The current record is 550 miles. That's 885km. And that as on a 85D, not the new 90D, which would put the expected result from the same test at 937km. Getting to 1000 in two years means going from 90 to 96 KWH in the battery, all else being equal. Considering that he's already stated that he expects a 5% improvement in the batteries every year, we would expect the 95D to be released next year, and the 100D the next, so that's right on schedule.

Comment No Osborne Effect! (Score 1) 398

The range increase he has predicted is 5-10% per year. The 1000km number is for hypermilers who figure out the optimal speed and ideal conditions, then drive all day at 22mph or whatever for the bragging rights.

The real maximum range right now is around 300 miles, and in 3 years, it could easily be 350 miles. I wouldn't be surprised if there's a bump when the Gigafactory comes online, as they may be able to build more tightly-packed custom batteries to increase density or otherwise incorporate new technology.

Anyone following Tesla knows full well that they are making engineering improvements every week, so every car is somewhat obsolete by the time you get it. But the cars are also so far ahead of anything else out there that there's no comparison.

Comment Re:Autonomy is already in 2015 Vehicles (Score 1) 398

Autopilot doesn't use the network. It uses radar and a camera to track the paint on the road. If the paint is faded, the sun reflects off it wrong, it gets confused with old paint, or whatnot, then it tells you to take control. I would expect to only need to take the wheel for 1% of the driving, but you would need to be ready to do so for 100% of the driving to be safe.

I'm sure there will be people who set out on a lonely highway and go to sleep, only to wake up when the car comes to an emergency stop on the side of the road because it decided it needed a human driver.

Comment Re:illegal autonomous cars? (Score 1) 398

He was clear in the interview that he thought it would take another 1-3 years before it would be legal, depending on the jurisdiction.

I read a review of the beta Autopilot feature expected to be released next month, and it's also illegal. It lets you take your hands off the steering wheel, which is illegal in some states. (I know you can be cited for it in Massachusetts; a state trooper said he used that to ticket drivers on cell phones if they gestured when he was looking.)

Comment Just one app (Score 3, Interesting) 151

What I want is a phone with just one pre-installed app: Setup. This setup app would recommend apps for various things like: App store, email, web, texting, contacts, camera, music, ebooks, etc. It would have recommendations for each, of course, but you could decide what makes sense for you.

They could still recommend all the same junk that they pre-install today, but without annoying their customers as much, while still getting some revenue from the app pushers.

This would also mean they wouldn't get complaints about using up so much of the built-in storage for the OS.

Comment Non-removable apps (Score 4, Insightful) 151

The problem isn't the requirement to include Google's other apps. The problem is that they're non-removable. If new phones came with just as much junk pre-installed, but if it were installed as if the user had downloaded and installed the apps themselves, then it wouldn't be a big deal.

Comment Re:Everyone needs an address so you can be tracked (Score 1) 435

True. My point was comparing IPv4 with a native address vs. IPv4 through a NAT.

Taking your story backwards, if the FBI intercepted messages with ISIS and recorded the network information:

Using a real IPv4 address: They get the account name and address from the ISP, then get a search warrant to find evidence and determine who in the home is the culprit.

Using a real IPv6 address: Same as above, only now they may be able to tell which computer in the house was used, making their job easier.

Using a NAT IPv4 address: The ISP is unable to tell the FBI which account is associated with the IP address. The FBI has to use other techniques to eventually determine who the bad guy is.

Of course, in the above example, the NSA would likely have a box inside the ISP that logs everything interesting, but if instead of the FBI, it was the RIAA, MPAA, or someone like that, they would be stumped.

Comment Re:Everyone needs an address so you can be tracked (Score 1) 435

You're missing the point. If you're accessing some IPv4 resource, and someone notes that the resource is being accessed, how hard is it to determine who was accessing the resource? In the old system, it's a simple matter of logging the IP address, and then using the courts to turn that into an account name. With NAT, you have to log the IP address, the source port, and the time, and then that only works if the ISP is keeping a log of every connection through the NAT, which is rather unlikely.

In other words, going through NAT provides some modicum of privacy. It's a far cry from using TOR, but it's something.

Of course, if you're accessing an IPv6 resource, then tracking by IP should work just like it has in the past.

Real computer scientists like having a computer on their desk, else how could they read their mail?
