Comment Re:Why isn't public transport 'free'? (Score 1) 198

If there is a lot of traffic regardless - say in a downtown area during rush hour - buses generate significantly more pollution than cars. Unless each bus is completely full, the emissions benefit may not cover the number of vehicles on the road.

Assuming that the average car gets 25 mpg, and the average bus gets even 5 mpg, and that idling emissions are proportional to the gas mileage, wouldn't it take just five passengers on the bus to equal one automobile with a single driver?

I'm not sure where you are at, but when I took the bus to work, I don't think I was ever the sole passenger.

Comment Re:Define "Threatened" and "Unwelcome" (Score 0) 765

Basically there's a war on men being men.

How do you define "being men"? There's facial hair, greater average strength, and other miscellaneous changes, none of which I'm seeing as being warred upon.

to sell out their gender

I suppose the bigger question would be how you can sell out your gender (penises taken from unsuspecting men and sold on eBay?) But there seems to be also an assumption that one should have more loyalty to their gender than, say, people who share their eye color.

Comment Re:This is why markets are not a good model for go (Score 5, Informative) 121

The government should not be constrained by market assumptions, such as that resources are limited because of efficient allocation.

That's not a "market assumption", it's plain old reality: resources are finite, so you need priorities. If a cop pulls someone over for speeding, then sees an armed robbery in progress, or a paramedic is treating someone's sprained ankle then a bystander has a heart attack, do you want them to stick to what they were doing and reject the notion of priorities as being a "market assumption"? I'd rather they focus their efforts on the higher priority, because that gives the best outcomes.

In this case, the FTC had more pressing enforcement jobs, like telemarketing scams, the fight with cellphone companies over ripoff premium services ... they felt putting their resources there made more sense than fighting Google over the order of search results, and I'm not at all sure they were wrong about that.

By coincidence, I was discussing law enforcement priorities at work on Friday (we teach computer forensics for law enforcement, among other things); unlike the world of CSI, real law enforcement doesn't go spending days testing out an obscure theory, or digging into every possible detail of each case: they do enough work on a case to pass it to the next stage, then get on with the next case. No "market" - there just aren't an unlimited number of hours in each forensic caseworker's day.

Comment Re:Use it or lose it (Score 3, Informative) 144

So, as with many of the bodies abilities; it's just a case of use that distance vision, or lose it when your eyes adapt to shorter ranges.

Except according to the article, that isn't the mechanism. It's the intensity of light that causes the body to prevent myopia due to changes in dopamine levels.

Not only that, but in animal studies, if chicks were given a drug that inhibited dopamine's effects on the eyes, they'd develop myopia in the same conditions that the control chicks would not.

So it's not "use it or lose it". It's "you need bright light".

Comment Re:From another article... (Score 1) 341

As someone who has spent a career working on safety-critical real-time systems, I can assure you that it's not in any way "much easier than people think". Quite the opposite. Sure, driving a car down a well marked highway on a clear sunny day with little traffic and no system failures is easy. But if you obscure the lane markings in any of a number of ways, add inclement weather, throw out random obstacles, random system failures, etc. the problem gets monumentally harder.

The criteria shouldn't be "a perfect AI" but "a better AI than a human driver".

Human drivers tend to be a pretty low bar.

I'm probably the same way. Got to milk my 3 digit UID for all its worth. :)

I've never gone to a meetup. I'd be self-conscious, feel out of place, and so on. Add travel, and forget it. If there was one here in Detroit, i'd at least consider it.

I did meet one slashdotter though. He got me an interview in Toledo. Though i don't remember who it was, i remember his smile when i came through the door and feeling good about meeting someone else.

Weird, I've never seen it with an S in there, only as LOC and xK LOC. I though maybe it was something different than the LOC counts I'd seen before. Of course, I've never dealt with projects that were in the millions either, so maybe that's why I've never heard the S variations.

Let's take the simplest of all the detection problems. How many lines of code does it take to reliably and safely detect the lane markings of a road? Nobody knows, because nobody has done it yet. Yes, there are prototypes that can handle some sub sets of all cases. The best I've seen handles 90% of the cases. That takes 1 MSLOC and still counting.

Comment Re:Erm (Score 1) 9

Inertia mainly - I stopped writing JEs regularly, and lost the drive to write them. Not sure what (if anything) would kick me back into any kind of regularity on them again. Though I suppose once every 18 months isn't too aggressive of a schedule to shoot for!

Submission + - The first stars in the Universe were invisible

StartsWithABang writes: You'd think it would be enough to form some stars, and "let there be light" would be a reality. But these stars don't become visible for literally hundreds of millions of years until after they form. It's not that they don't emit light — they do — but rather that the Universe is opaque to that light for up to half a billion years after those stars form. While modern telescopes like Hubble are inherently limited by this fact, the James Webb Space Telescope, which will observe in wavelengths that these dusty particles ought to be transparent to, might be able to finally probe the true light from the very first stars.
