Speed Cameras In Chicago Earn $50M Less Than Expected

beelsebob Re:Easy to solve - calibrate them to overestimate (366 comments)

So what you're saying then is that it's fine to break the law, and put other people's lives at risk by speeding through a junction as the lights change, as long as your car is powerful?

Speed Cameras In Chicago Earn $50M Less Than Expected

beelsebob Re:This is good (366 comments)

No, just predicting income does not imply that you don't think the ideal income is 0. I can also predict that in an average job I'll have to go in and actually do work 40 hours a week, even though I think the ideal is 0.

Speed Cameras In Chicago Earn $50M Less Than Expected

beelsebob Re:This is good (366 comments)

The point of the cameras was revenue, not traffic safety.

Says the article...

No one else has claimed that. They merely predicted that driving was bad enough that it would happen to bring a certain revenue. It turns out that driving is better than they thought, and now they're happy.

Speed Cameras In Chicago Earn $50M Less Than Expected

beelsebob Re:Easy to solve - calibrate them to overestimate (366 comments)

No, you apparently don't. In every state I'm aware of yellow means "stop if you can". It's effectively red, but lenient enough that if you're close to it and can't stop when it appears, then you're still fine.

It's amazing how many people who claim to have a sub 0.4s reaction time suddenly have a 4 second reaction time when faced with a yellow light.

In UK, Internet Trolls Could Face Two Years In Jail

beelsebob Re:So what qualifies? (483 comments)

They're not - the judiciary and the government are entirely separate entities in the UK. Hence why the judiciary can preside over cases against the government.

JavaScript and the Netflix User Interface

beelsebob Re:Why the hell... (192 comments)

The JVM has opcodes for allocating objects and calling methods on them

And there are many languages out there that don't work in terms of objects and calling methods on them ;).

JavaScript and the Netflix User Interface

beelsebob Re:Why the hell... (192 comments)

The JVM is very language specific. For example it has op codes for allocating java objects. A truly cross language virtual machine doesn't have anything anywhere near that high level or specific to a particular language.

Second, javascript can be the compile target of LLVM bytecode. You can compile your favourite C program to js

But in doing so will lose all of the ability of the compiler to see what you actually wanted to do, and to optimise your code.

asm.js can be set as target for emscripten. The browsers supporting asm.js simply JIT it to bytecode, and those which don't still can run asm.js, but way slower.

Alternatively, we could skip the added complexity of javascript, and just provide the byte code directly to the browser.

JavaScript and the Netflix User Interface

beelsebob Why the hell... (192 comments)

Why the hell are we still stuck using Javascript for the web? Why have we not got some virtual machine (not a language specific one like the JVM), that we can compile any language we like to? Half the world is trying to hack around javascript's shortcomings. If even half that effort was directed at making PNaCl viable on all browsers, we would be so much further forward.

Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

beelsebob Re:No mention on capacity though (395 comments)

Sure it would –it just wouldn't last 20 years. With charging in a few minutes, I think he's perfectly capable of charging it while he's working. So that's 2 charges a day, or one every 12 hours. That means it'll last 13.7 years. To be honest, that's a pretty reasonable length of time for a car.

Flight Attendants Want Stricter Gadget Rules Reinstated

beelsebob Re:That's not the reason you're being ignored. (405 comments)

That's true in low speed impacts, especially ones where your head is otherwise protected. It's not at all true in accidents where a lot of energy is involved. When you're talking about 50g deceleration, the most important thing is to make sure that the head doesn't accelerate rapidly away from the spinal column. That's why Formula 1 drivers wear a HANS (Head And Neck Support) device - to stop the head pulling forward off the spine in a crash. The brace position does a similar thing.

Flight Attendants Want Stricter Gadget Rules Reinstated

beelsebob Re:That's not the reason you're being ignored. (405 comments)

Sadly, the typical crash involves the plane ripping itself apart and burning the passengers alive. Only a few rare accidents have the plane smash into a building.

Actually, no, surprisingly. Not only is your likelihood of being in a plane crash lower than that when driving, but... Even if you assume you're doing to be in a plane (or car) crash, your chance of surviving are actually higher in a plane. 75% of people involved in a plane crash survive. Meanwhile, only 50% of people involved in a car crash survive.

That seems pretty reasonable if you're talking about a car with a decent range. It may even be overkill.

Flight Attendants Want Stricter Gadget Rules Reinstated

beelsebob Re:That's not the reason you're being ignored. (405 comments)

and it takes me all of two seconds to remember where the exits are

Actually, this is the one important bit of the safety briefing. It's been shown multiple times that in an emergency situation we're surprisingly shit at figuring out where we should be going. Not only that, but one person trying to fight the flow and go to the wrong exit can fuck over many many other people. Just prompting people to look around and register in their brain "it's 3 rows behind me" is useful.

beelsebob Re:That's not the reason you're being ignored. (405 comments)

Bracing does nothing to improve your chances of survival, in some cases it makes less likely you'll survive.

Not true, as multiple actual scientific studies, and, more popularly myth busters have shown. Assuming the brace position significantly reduces the acceleration your head undergoes, and hence significantly reduces the chances of traumatic brain injury.

beelsebob Re:That's not the reason you're being ignored. (405 comments)

I'll take my chances that even if I did brace for impact it wouldn't make a significant difference in my survival or chance of injury.

Actually, the brace position does have a huge effect on your survival of a crash landing. It stops your head accelerating rapidly forward, and then backward relative to your body. That illiminates a whole huge class of possible brain injuries.

Don't argue the "ignore the flight safety briefing" point - that's a red herring.

They're not saying "it's unsafe" therefor we shouldn't have it. They're arguing "we don't like it very much, so we're going to tell you about safety so that you think we have a point".

Experts Decry Randomized Ebola Treatment Trials As Unethical, Impractical

beelsebob Re:Our PC society will be our demise! (193 comments)

Yes, damn those white people for SIMPLY WANTING TO LIVE AROUND THEIR OWN KIND.

Yes, damn them for that. Yes, damn them for being so self centred, biggotted and idiotic for believing that somehow people who were born in another country are not worthy of being around them.

Apparently, YOU believe that white people are so 'superior' to non-whites, that to prevent non-whites from living around is to deprive them of something,

I'm sorry, but what the hell? You literally just claimed that depriving them of something (in this case the ability to live around you) is not depriving them of something.

Apple Switches (Mostly) to OpenStreetMap

beelsebob beelsebob writes  |  more than 2 years ago

beelsebob (529313) writes "In the recent release of iPhoto for iOS it appears that Apple have started using OpenStreetMap's data. Unfortunately, there are still some problems. Apple are currently not applying the necessary attribution to OSM; they are using an old (from April 2010) dump of the data; and they are not using the data in the USA. Fingers crossed apple works through these issues quickly!

Apple are now one of a growing list (including geocaching, and foursquare) to Switch2OSM."

Apple drops iPhone Developer NDA

beelsebob beelsebob writes  |  about 6 years ago

beelsebob (529313) writes "Today Apple dropped the iPhone developer NDA.

We put the NDA in place because the iPhone OS includes many Apple inventions and innovations that we would like to protect, so that others don't steal our work. It has happened before. While we have filed for hundreds of patents on iPhone technology, the NDA added yet another level of protection. We put it in place as one more way to help protect the iPhone from being ripped off by others.

However, the NDA has created too much of a burden on developers, authors and others interested in helping further the iPhone's success, so we are dropping it for released software. Developers will receive a new agreement without an NDA covering released software within a week or so. Please note that unreleased software and features will remain under NDA until they are released."

Squirrelfish takes a bite out of performance

beelsebob beelsebob writes  |  more than 6 years ago

beelsebob (529313) writes "We all recently heard that Google Chrome had introduced a new Javascript engine called V8, that made all the other engines out there look like toys. Today the WebKit team announced that their Squirrelfish engine has been optimized a lot more, to produce Squirrelfish Extreme. The improvements are enough that WebKit now runs Javascript faster than Chrome. The competition between browser makers seems to be paying off for us consumers with some major improvements in performance now."

beelsebob (529313) writes "Very well known is the iBook G3 logic board failure issue, however, less well known is that iBook G4s have been failing with the same symptoms almost as regularly. The G4 variant of the laptop is not covered by Apple's logic board repair program, thus if it dies, it's dead. Or so we thought, until recently. An enterprising guy has posted a fix for the problem that works simply by sticking a tiny bit of plastic under a chip."
