What most people think it looks like when you change router's admin password, apparently

Seajay#

The random looking keys are random. From the article:

Andy Patel, security expert at F-secure, agreed that newer routers tend to come with a randomised Wi-Fi Protected Access passwords.

Which makes the whole premise of the article (that people are doing something wrong by not changing the password) false. In fact if they did change it they would almost certainly make it worse.

Re: Some points about passengers and P2P

I don't think every kilo of water that you drink on your trip to mars is going to be a brand new bottle of Fiji water. It's going to be urine recyc. So maybe 3.5kg of emergency water per person (total not per day) and perhaps a 20kg machine with a 100l holding tank, plus a standby plus some spares and tools. That brings the water down from 63 tonnes to ~1/2 tonne.

Re: Optimistic

True, AVs are unlikely to be able to get that degree of reading the intentions of pedestrians for an extremely long time. But how big a deal is that? If you're moving through at 30mph, an average human probably isn't going to spot that amount of detail either.

For a human driver to have the the time to see evolving dynamics between pedestrians and the spare capacity to be watching them in the first place you've got to be doing what 10mph? Less? At that speed the stopping distance of an AV is just a few feet. So while the human driver might be better in the sense that they can spot it earlier and brake sooner, they're probably not better in the sense of actually preventing any accidents.

Seajay#

Re: Optimistic

This could be one of the greatest relative strengths of AVs. Once they're out there you don't necessarily have to wait for a crash or disengagement to learn. Here's an interesting blog post from Tesla on this subject. It describes how they use fleetwide learning to whitelist particular radar returns in particular areas to avoid false positives.

https://www.tesla.com/en_GB/blog/upgrading-autopilot-seeing-world-radar

As well as recognising specific items, presumably it could be used more generally and even in cases where there was no collision and no false positive causing unnecessary emergency braking. I.e. my car sees something which it assumes is a far away truck, as we get closer, it realises that it is a nearby van. It can send to Tesla, "image A was incorrectly classified as a truck", if Tesla get lots of those they can tweak the image classifier. Similarly on the control side it can say, I wanted to change course from A to B so I applied control input X. I actually ended up on course C and therefore applied correction Y to end up on course B. As far as the passenger is concerned nothing bad happened but my AV knows that its internal model of the car's dynamics must be wrong. They can send that to Tesla who can either say "Get your suspension / tracking / tyre pressures checked" or if they see it from lots of cars then they can change the control model.

Re: I can't see full AV either

Firstly, does it assume maps are entirely reliable? I don't think that's true at all, they read road signs and markings (not perfectly at present but they're getting there)

https://www.citylab.com/transportation/2017/02/how-to-teach-a-car-a-traffic-sign/516030/

The second problem doesn't seem like a driverless cars problem to me. If a human decides they want to deliberately cause an accident by driving on to my side of the road immediately before we are about to pass in opposite directions there's not a damn thing I can do about it and there's nothing a driverless car can do about it either. I don't see how AVs make that worse

Third problem is related to the first. That's only a problem if you assume that AVs navigate solely by GPS and maps, but that's not true, they navigate by GPS, maps, cameras and (maybe) lidar.

The fourth problem is a fairly minor UI issue, how do I indicate where I want the car to go if there is no map of the area. Well either the car takes me to the nearest mapped road then puts me in to a semi-manual mode for the last 10m where I direct the car with a joystick and it continues to handle all the collision avoidance and actual control of the car, or I indicate on a satellite map where I want it to go, or something similar. Even if the answer is that no, you can't park anywhere that's not on the map, that's still not fatal for AVs, there just needs to be some way for you to get your own drive added to the map and you'll have to accept that you're otherwise going to have to park in car parks or on the road side.

I can see some arguments for the fact that getting the last 20% of the way to AVs is going to need much much more work than the first 80% but I can't see anything which is a complete show stopper.

Elon Musk offered no salary, $55bn bonus to run Tesla for a decade

Seajay#

Re: I get this sinking feeling....

Surely that's precisely the point of this plan. Unlike every other CEO he can't make money off some short term movement in the share price or by standing still and collecting a salary.

For Musk to agree to this plan he has to believe that the company is going to be fantastically successful over a long period because if it's not he doesn't get paid. If he thought it were all smoke and mirrors then he'd go for a high salary and make sure that there was a great severance package written in to the contract.

This is a clear and expensive (therefore trustworthy) signal that he believes it's going to change the world.

Whether it actually does change the world is another question, but he clearly believes it.

WikiLeave? Assange tipped for Ecuadorian eviction

Seajay#

Re: Time for a chat ...

Why would the UK judiciary agree to that? Even if they were able to deviate from the law for this one person, why would they want to?

Either Ecuador host him for ever or he eventually walks out, pays for his crime of jumping bail, then gets extradited to whoever wants him. Either of those options are fine for the UK. Why would we feel the need to make some sort of shady deal?

One of those options is a PITA for Ecuador so I can see why they want to make a deal, but they aren't holding any cards.

Seajay#

But he hasn't been confined to the Ecuadorian Embassy. He has been there voluntarily. You can take in to account time served in pre-trial custody but you can't (and wouldn't want to) take in to account time on the run (which is what he currently is). If you did that, it would encourage people to jump bail which is precisely the opposite of the point of the laws around bail.

Maintaining respect for the law around bail is far more important than the fate of this one guy.

That’s exactly the problem. Ordinarily this would be "No crime committed. HR investigate and sack if necessary" but there is no HR equivalent, MPs are self policing.

Re: I'm sceptical

but according to the data we're behind the French, with their 9.7% unemployment, over 1 in 54 of under 25s unemployed, and their shorter average working hours than the UK

We're behind the French because of those things, not despite them. Productivity is output per employee hour. Make a bunch of people unemployed and it will generally be the less productive ones who are sacked first. Mostly employ over 25s who are already trained and experienced and your productivity improves. Go home early and you might get less work done in total but the amount of work you've done per hour will probably be higher.

So I don't see any reason not to trust the productivity data. Though there is a very good reason not to see it as the only thing you need to worry about.

Re: Next step

If they do that (and make it clear that's what they're doing) then it's absolutely fine.

If they're providing me with something of so much value that I want to leave it open all the time, it's perfectly reasonable that I should provide them with a bit of mining time. The current situation is a problem because a domain squatter whose site I don't actually want to see at all might be able to trick me in to mining for him.

The better model I think (and it's one which is heavily promoted by CoinHive) is mining as a catcha replacement.

Level 5 driverless cars by 2021 can be done, say Brit industry folk

Seajay#

Re: Determinism

A factor of 2 by definition means half as many accidents if they replace all cars so that's got to be good from a utilitarian point of view. However, there's quite a lot of variation between human drivers so if driverless cars are only twice as good as the average, that means that some people are being put in more danger than they were in before. That's going to be a tough sell.

As a strange extra statistical wrinkle, consider that middle-aged people are the safest and also the most likely to buy their car brand new, unlike the dangerous teenagers. So it could well be the case that if new driverless cars are twice as safe as average, they could increase accidents when they are first introduced as only people who are three times a safe as average buy them.

Re: Determinism

Re: Economics is the problem

You're right. But it's not the case that insecure systems are causing loads of death but it isn't visible. It's just not causing much death. Therefore the right response is don't worry about it. Or more precisely, worry about it but don't spend as much money as you do keeping aircraft safe.

Re: Economics is the problem

Rather than say

Re: Space X...

I'm not sure that's a great analogy.

If typical software contained bugs which were so serious that they caused the server hardware to be destroyed after each request (roughly the non-reusable rocket equivalent) then yes, there would be huge economic gains to be had from working on reliability, but that's not the situation.

That doesn't mean that we shouldn't look to improve reliability, just that unfortunately we have to accept that there is a trade off, it won't pay for itself.

Military test centre for frikkin' laser cannon opens in Hampshire

Seajay#

Usage

For about 100 years naval gunfire has been able to fire further than the visible horizon. Replacing the main armament with something which can't possibly fire that far because it has to be line of sight and even in the best of conditions would be skimming the surface of the sea and therefore getting lots of deflection from the moisture gradient, spray, etc, makes no sense. Also, delivering enough energy at long range to do more than temporarily blind another ship is probably impossible. So that's probably not the use.

Anti-air / anti-missile probably makes a lot more sense. They are closer or higher so the range and distortion is less of an issue. The amount of energy you need to deliver to a missile or aircraft to destroy it is much much less. They can't be made reflective or they lose their stealth. Extremely rapid tracking and extremely low time-of-flight is important, which plays to the strength of lasers. All in all most likely this is a CIWS replacement / augmentation. It could also do a great job of blinding enemy pilots at extremely long ranges. That's illegal but so long as you can make the argument that you were trying to burn him rather than blind him, it's all fine, history is written by the winners.

Worrying about swarms of RIBs with explosives in is the terribly modern thing for the Navy at the moment, I suppose a laser would pop them in a highly satisfactory fashion too.

Seajay#

That occurred to me too. Maybe it's fine because the enemy deciding to cover his crucial assets in the most high visibility materials possible would be a win for us even if we never fire the laser.

Re: Cost

I'm not sure it's irrelevant, but yes it's not the whole story.

I suspect that part of the higher cost of ebooks now is that they are under tighter control. You can't resell second hand ones, you can't take them out of the library both of those things limit the price of paper books but not ebooks. Plus it's just plain old market forces; ebooks are more convenient, people will pay higher prices for them, if people will pay more, copyright owners will charge more.

Re: Cost

That's because you pay VAT on ebooks but not on printed ones.

This is the same as raising the minimum wage artificially until robot burger flippers and ordering kiosks become very cheap in comparison to low skill labor.

This is the exact opposite of that surely? You just said a few lines higher up that this will let companies pay low-skilled employees less. If this policy means that their total income in unchanged but they are more likely to be employed because less of that money has to come from their employer, that's.. well it's not great because they're still flipping burgers but it's fine, it's better than the alternative.

Seajay#

Great idea but..

That's usually people's response. I disagree. The only time it's a great idea is if your problem is "The world is way too rich. How can we possibly share out this bounty?" and that's not our problem. If all we had to do was feed ourselves we'd be in that position, producing as much food as anyone could want cheaply is pretty much solved. But we also have to provide healthcare. Trying to prevent mortals from dying can always absorb as much money as you can throw at it without ever being solved.

If we're not too rich then the fundamental problem with UBI is that it spends a mindblowing amount of money while actually making the most needy worse off. If you try to solve the 'making the needy worse off' problem by running a parallel means-tested system then you still have most of the problems of UBI but now you get none of the simplification benefits.

It's a very appealing idea, I get that. But it just doesn't work, even in theory and that's before you start to get in to fraud, etc.

Re: Colonist motivation

Well, economics is really about the movement of money (resources, economists might like to say, I suppose, but really it's just money they're talking about).

It absolutely isn't about the movement of money and it very very much is about the movement of resources, enormously expensive resources which need to be moved at a vast cost of even more resources. It's no good moving a derivatives contract for an atmospheric regulator to Mars, you need the actual machine there, or you can't breathe. Someone on earth needs to have made that machine and someone needs to have provided them with the raw materials to do so. Who is that person paying the manufacturer? paying for the rocket fuel? paying for the raw materials? and why are they paying out so much when they're getting nothing from Mars?

Cloud lesson

I don't think the lesson here is never buy anything which relies on a service run by someone else to be useful, because actually in this instance it's absolutely fine. If you have an in warranty link, it gets upgraded to a harmony hub for free. Great. If it's out of warranty you've been given notice and you get a discount. Not great but fine.

Contrast that with pebble, where your watch just stops working.

So the lesson is, if you're going to rely on someone else's service continuing to run, make sure they're a big company with a reputation to protect.

Re: Interesting

so long as it dnla's then the netflix/youtube/etc can stay on my phone.

Well there's the real killer. Does netflix on your phone allow you to play on a remote renderer? I don't know about netflix specifically but I know for sure that NowTV doesn't (though it does allow chromecast), even free to air stuff like Channel 4's catch-up service doesn't allow that. How is that going to work when you're glamping so presumably using mobile data? In that case your phone and the projector can't possibly be on the same network.

Possibly you can have a wired connection your phone with an MHL or a Lightning Digital AV Adapter (£50!) but now you're carrying a bunch of cables as well so you're losing a bit of the magic.

Ideally it shouldn't matter but in reality, that integration stuff is going to be make or break for this sort of device.

Re: Attention Test Required

It's a good idea but the thing is you can get away with that if you're writing code for a company to be used by employees. They know they're there to work so if you add (what seems like) a condescending we-don't-believe-you-can-pay-attention-unless-watched test then they put up with it because they want to get paid. If you're selling a product to people it's a very different relationship. If you lock them out of a feature of their car, which they have paid for because they failed your test, they are going to go nuts.

Like I say, it's a good idea but it's just not going to fly. If that means that we go straight to level 4 and it takes a few extra years, then that's what has to happen.

However, the big benefit here is not owning a cool car but reducing climate change both immediately from the reduction in emissions by the rich person who now doesn't own a range rover and in the longer term as the EV R&D makes its way in to cheaper cars and ultimately all cars.

That benefit goes mostly to the poor.

Re: Global Nuclear Strike

This is batshit insane but it's batshit insane in quite an illuminating way.

We've got very used to fighting forces armed with the strategic equivalent of a sharpened mango (though that mango has been brutally effective in tactical engagements). So we've got used to overwhelming air dominance and we've poured a load of money in to vehicles which have excellent IED resistance but zero being-shot-at-by-a-T-14 resistance. The idea of delivering nuclear weapons by A380 comes from the same mindset but it is ridiculous.

We're probably never going to use our nukes but if we did it would only be against a peer adversary which means they will have a functioning air force who will be jolly keen to avoid nuclear bombs being dropped on the motherland. Such a force wouldn't have too much trouble intercepting as many A380s as we are able to send. If they don't have a functioning air force but we do then we wouldn't nuke them because we're going to be able to win a conventional war quite easily.

Re: Other options

But that intrusive data gathering is also what makes search work and voice recognition, translation, spam filtering, etc so they would have to do that anyway if you wanted it to be just as good and that means your $5 doesn't buy you any privacy all it would buy you is the removal of the ads and for me that wouldn't be worthwhile.

There's another problem. Of those 1.5 billion users, many of them are way too poor to make $60/year for Google. The ones who make it worthwhile are the rich ones but if Google offered an opt-out option, that would be disproportionately taken by its richer customers. Then they would find themselves in the situation where almost all of their ad revenue disappears but only a small proportion of their customers are paying them. It could only generate them the same revenue if all 1.5 billion paid and that isn't going to happen.
