Speed Cameras In Chicago Earn $50M Less Than Expected

Captain Hook Re:Financial gains over safety (397 comments)

Either they totally overestimated the speeding issue, or they underestimated the dissuasive effect of those cameras (which means they work actually pretty well... assuming they are correctly placed).

In both cases, a data set of vehicle speed at the site in the year before and after the cameras were introduced would be very useful.

Case 1: No change in traffic speed
Case 2: Dramatic reduction in traffic speed

Assuming they had that data set.

Case 1: would be kept as quiet as possible because it means the camera were either not needed for safety or not put in for safety.

Case 2: would be shouted from the rooftops (from both the local authority and the company running the scheme) because it would have shown a positive safety effect which is how these scheme are always sold as being a benefit to the community.

Mysterious Feature Appears and Disappears In a Sea On Titan

Captain Hook Re:subsurface terrain & tides (65 comments)

I know it's unlikely, but if the shore was made up largely of vertical walls rather than slopes, then a tide wouldn't change the shore line much but could reveal sub surface shelves.

Gas Cooled Reactors Shut Down In UK

Captain Hook Re:Oh look it's mdsolar again (120 comments)

The system and safety protocols are working precisely as they were designed.

Actually, the faults were found by chance, there wasn't a specific check for this which could be scheduled and signed off, it was just an engineer noticed something odd while doing other inspections.

So while you are right in that this is not a huge safety issue and we weren't minutes from disaster, I wouldn't agree that the system and safety protocols are particularly brilliant either.

Ask Slashdot: What To Do About the Sorry State of FOSS Documentation?

Captain Hook Re:Software Documentation is bad everywhere (430 comments)

The stories would be of the form:

As a user, I want to change my password...

But they generally won't say that the means to do that should be a link from the user account page or what the steps of the process would be. Now for something simple like a a password change, there are generally well defined industry best practices that both the developer and the end user are probably aware of and so both have a common conception of what should happen. That isn't true for functions specific to the application or domain.

There is a big gap between User Story and implementation specific documentation.

Dropbox Head Responds To Snowden Claims About Privacy

Captain Hook Re:I think people are missing the point (176 comments)

Use the web interface to download the file, then decrypt with a local copy of the encryption tool/key.

What they mean is they can't render a document on the web interface.

Brazil Nut Effect Explains Mystery of the Boulder-Strewn Surfaces of Asteroids

Captain Hook Re:That's how I clean my cat's litter box. (58 comments)

I would have intuitively said the other way around.

Since the gravity is so small I would have expected the motion of the smallest particles to be close to random, perhaps close to Brownian motion if you looked at the system over a long enough period of time.

I guess, even though there isn't much to pull the material together, once a small particle is in a crack or void it is very unlikely to ever escape and so the crack does eventually fill in, it seems to me that the process should exist but be much slower than when compared to the effect in a strong gravity field.

As you said, "Intuitively, which we all know is probably wrong"

Brazil Nut Effect Explains Mystery of the Boulder-Strewn Surfaces of Asteroids

Captain Hook Re:That's how I clean my cat's litter box. (58 comments)

But does the process work when the gravity field is tiny? That is what needed to be found out before saying that that is definitely the process at work.

Solar-Powered Electrochemical Cell Used To Produce Formic Acid From CO2

Captain Hook Re:Amazing technology (133 comments)

The coal we use was created before bacteria evolved the ability to decompose trees, so it's not quite as simple as you seem to think...

How Often Do Economists Commit Misconduct?

Captain Hook Re: Political/Moral (305 comments)

I'm not sure you understood the GP's point. In fact you seem to have interpreted it completely backwards.

Allowing the companies making the loans to go bust, rather than trying to protect them by not allowing Student Loans to be cleared by bankruptcy is the attenuation that you are looking for. It's sends a clear message to other companies loaning money that there are risks and that they should be filtering potential customers.

How Often Do Economists Commit Misconduct?

Captain Hook Re:Political/Moral (305 comments)

If economists had known in advance of one of the great depressions that it was going to happen, and releasing the results would of only sped-up the collapse, should they release the information?

The earlier the bubble is burst, the small the correction needs to be and the quicker the recovery afterwards can be. Knowing a burst will happen, it is ethical to make the information public as quickly as possible.

The tricky bit comes when you are 55% sure of a crash, but knowing that making those fears known publicly will definitely cause a crash. How sure do you need to be before it is worth causing a small crash to offset the chance of a bigger crash later on? 60%, 70%, 80%?

Massachusetts SWAT Teams Claim They're Private Corporations, Immune To Oversight

Captain Hook Re:Libertarian nirvana (534 comments)

I would have thought that lack of crime was the goal of any law enforcement, not number of arrests. Although number of arrests is certainly an easier number to work out.

Auditors Release Verified Repositories of TrueCrypt

Captain Hook Re:7.1a for x64 linux (146 comments)

Authorities can only do that if they don't mind revealing the investigation against someone. There are still alot of reasons why authorities would want to be able to read something encrypted without it being obvious that they are doing so.

Tech Worker Groups Boycott IBM, Infosys, Manpower

Captain Hook Re:Same Manpower as in Canada? (234 comments)

except that the idea of foreign workers being prefered over domestic, regardless of the reason, is a widely held believe.

Evidence that that is not the case would be just as worthy of publication

NRC Human Spaceflight Report Says NASA Strategy Can't Get Humans To Mars

Captain Hook Re:If only ... (206 comments)

The number of brainfucks in Washington could be turned to our advantage.

We only need to introduce a single letter typo into a funding bill and for the brainfucks to not notice.

Captain Hook Re:Same Manpower as in Canada? (234 comments)

If there's a big bias against Americans in the results, publicize the heck out of it.

Regardless of the outcome, publicize the heck out of it. You don't get to hide the results just because they don't confirm your pre-existing bias.

Whistleblowers Enter the Post-Snowden Era

Captain Hook Re:Some thing are not worth aiding (129 comments)

Do you stand to gain, directly or indirectly, any benefit either personally, professionally, or politically, by whatever is being whistle blown on?

That is an extremely wide difinition.

Anyone whistle blowing is doing it because they want something changed, whether that is an improved working environment or a social/political change. That means they are indirectly benefitting and therefore by your definition no whistleblower is a whistleblower.

Driverless Cars Could Cripple Law Enforcement Budgets

Captain Hook Re:Cops need doughnut money, too! (626 comments)

There will still be plenty of tickets to write for a long time, as until we are at 100% adoption, people will still break trafic laws

I'd imagine there is a network effect which would dramatically reduce traffic violations even with a realtively small proportion of fully automous vehicles on the road.

You can't speed if the car in front is doing 3 mph below the speed limit, you can't run the red light if the car in front is already slowing down for the amber. As the proportion of automous vehicles increases, people will get used a more conservative driving style and their driving style will change to compensate.

I don't know the proportion of traffic which would have to be automous to have an affect, but it will be far less than 100%

Curiosity Rover May Have Brought Dozens of Microbes To Mars

???

Because it has a lot of implications about how life gets started on a planet which is an important line of investigation for science, isn't that obvious?
