Look inside ELON MUSK'S CAR! Tesla S wundervehicle has voom

Re: Superchargers Free!

This may have gone over your head, I was using scientific notation in order to get across the magnitude of the issue at hand. If li-ion electric cars are the solution to our reliance on oil, then what is required in order to have a society pretty much like ours where transportation is a personal freedom.

You can clearly see from the numbers that producing enough li-ion batteries cheaply enough or in sufficient quantities to power the worlds vehicles. It is not like li-ion is a new, barely investigated or exploited technology that can be easily made cheaper to produce, it is already at scale, and producing the kind of cells that go in to a Tesla.

So, we have a technology, cool as it is, that is not going to "save the planet", it is not going to reduce vehicle emissions, since only a tiny proportion of upper middle class people and their delivery drivers will be driving one. Fine. The problem comes when these users insist that the rest of us pay for their toy with infrastructure investment in to the grid so that they can use it as they like.

This comes after the same people force us to pay for thousands of miles of new grid to get cables offshore and to the top of hills, which could have paid for every coal fired power station in the UK to be replaced with nuclear.

Re: Superchargers Free!

For everyone in the UK to change to an electric car within one year, we would need to build more lithium ion batteries than have ever been made since they were invented.

Math:

Registered vehicles in the UK: 3.5x10^7 vehicles

Li-ion cells in each Tesla S: 7x10^3 cells

Worldwide Li-ion production: 6.6*10^8 cells

Years of current worldwide Li-ion production to equip UK with enough cells for cars: 371

Li-ion powered cars: for the rich only. Being smug about "saving the environment" whilst you use 10000 times the resources of the next guy to get to work - priceless.

UK govt 'tearing up road laws' for Google's self-driving cars: THE TRUTH

Re: @'s water music

Modern airlines can and do practically fly themselves, including take off and landing.

And they do this by operating in largely uncongested space using scheduled flight plans and whole teams of meatjobs in centres around the world to ensure they don't crash when they do get in crowded spaces.

It is possible to write software that is as near to perfect as possible. It just takes a lot of effort and great care.

In flight's case, by putting constraints on the variables in a way that is not possible with current road traffic, and using mechanical turks in the form of air traffic controllers. If there is a human in the box, it's not automation folks.

Re: I'm against it at this time. here's why...

should the cause of the incident be attributed to the decisions made by the autonomous driving software rather than, say a human driver's bad decisions.

Interesting. Currently, it is almost always a human driver's bad decisions that cause an accident, however we do not assign blame like that - you can make all the wrong choices, cause a serious accident and not have any blame assigned to you - quite rare though, Id have thought.

Say there was a death. The CPS have to determine if they can get a prosecution for manslaughter, for dangerous driving or for driving without due care and attention (not full list, some names probably wrong). Sometimes, it is just bad luck.

Now, this is hard enough to do even when it is a human driving and can tell you what they did. How do you determine if a computer program was driving dangerously? If the radar detector is dirty and your autocar runs in to the back of someone, are you liable, as you didn't clean the sensor, or is the software liable, because it didn't detect the sensor was faulty? If it's you, are you "without due care and attention", or is the software "driving dangerously".

GAME ON: Top 10 tellies for a World Cup kicking

Re: Sir

The good TV has the good image processing chip in it that costs £100 more than the other. Well, it costs you £100 more. However, because it costs you £100 more, they don't put it in the basic TVs, they only put it in the fancy ones.

Therefore, if you want the best picture, you're going to need to need to buy one with a bunch of stupid features that you won't use, and probably don't even work that well.

Don't expect anything to ever get fixed on your TV. If it doesn't do it when you buy it, it probably won't ever - so demo if there is a specific feature you want.

When you do go buy a TV though, don't worry. Pick one that is cheap enough for you to not cry and has a good enough picture, and then get it home. Looking at racks and racks of TV screens trying to say "this one is better" and then "no wait, this one" is a disaster, pretty much they will all look fine when you get home.

Finally, don't buy any of the TVs listed here. El Reg is only listing new models of TVs, save yourself a fortune and go to Richer Sounds and get the model that the new model replaced - roughly the same features, roughly the same spec, around half the price. Even the cheap one El Reg listed, you can get a better cheaper one if you don't buy the very latest cheap model!

Re: So....

Oh now I sense some angst. Please ask Kirk McKusick, he knows the story about why this is not being disclosed to FreeBSD. Sometimes I feel a bit sorry for them (and for him), but then the next minute I don't feel sorry because there's damn good reasons they won't be told about what I found.

Google reaches into own silicon brain to slash electricity bill

Re: All good stuff

Especially as in a DC, power is your biggest cost. If your devices use less power, then they generate less heat. If they generate less heat, you can pack more of them in per rack. If you can pack more in per rack, you can have more devices in the DC period, and the cost of hosting is reduced.

I'm sure google have well specified DCs, but we often can't fill our rack because our DC provider can't* sell us more power, because they are near their cooling limit. If we used less power, we could have more per-rack, and we would need less racks/have more servers.

* Of course they can give us more current, but it is exponentially expensive, to the point where filling a rack (using say 22A) is almost as expensive as taking another whole 13A rack.

Re: CI != Code Review?

Except when the client or management say that it HAS to be patched up and out the door for the trade show or that there's no more money left and we have to go with what we've got (plus a little unpaid overtime).

Yes, every two weeks we re-evaluate everything we are doing to determine whether it is still worth doing more work to that for the business (not us). We tell the business how long it takes to deliver quality, so if we haven't got enough time to deliver quality, either we've been slow or we're bad at estimating.

Given we are only estimating tasks that take less than 2 weeks, you really can't be that far out. And if the feature you're working on was scored for "2 days work" (thats not how we score things), and it takes 10 and is still not done, then you either didn't get enough details from the project owner (hence his fault - the job of the project owner is to give well specified tasks to the team), or the task is overly complex and should be re-evaluated anyway.

Before you move to a scheme like this, you have to have buy-in from all the key stakeholders , so that when that trade show rolls around, you can easily say "No. This was not agreed on. If you want us to work on things, you have to present it through the project owner who will prioritize your requests alongside everyone elses.".

I've happily said this to C-level execs, they agreed this working model. This shifts the discussion about whether you do something away from your team; it's then a business decision, and they can horse-trade all they like in order to change what you do *next* sprint - no-one can change what you do *this* sprint.

Re: CI != Code Review?

CI != "automatically push to live"

CI is having processes in place such that you can be confident that you can always push to live without breaking things.

We do things on a 2 week sprint cycle, which means every task, change request or feature we do must be fully complete, tested and deployable by the end of those nine days (or it gets re-scored for the next sprint).

Once the sprint is complete, on the tenth day we demo the completed tasks to the commercial team, the maintenance team and then release to live.

During the sprint, the maintenance team will make as many maintenance releases they need, all also underpinned by CI - or they might kick things back to us if we broke them in the previous release.

1) Feds have taken control of the botnet's C&C servers

2) The botnet is currently idle, as no instructions are being sent from C&C servers

3) It will only take approximately two weeks for the botnet owner to setup new C&C servers and 're-capture' the botnet.

4) Now the feds just have control of former C&C servers.

When Russia or China do something like this, it is the State determining what content is available. This is individuals being given the ability to correct incorrect information held about them in a database by a company, and is in fact a right we in the real free world have had for a long time.

Re: Confused

You're not a little confused, you're a lot confused.

Peter Sutcliffe cannot have his past forgotten because it is still relevant. He can apply to Google to have his past forgotten, Google can say "Fuck off and get a court order", and the court will simply say "Fuck off".

The recent court judgement says that when the court does order Google to remove invalid or out of date data from their database, Google must do so. Google's argument seems to be "bwaah! don't wanna!"

To clarify, the information is in Google's database, which is the link between the keywords searched for, and the resources found for those keywords. This judgement is that where a court has ruled that the resources contain invalid or our of date data that contravenes someone's right to privacy, then Google must not link certain keywords to certain resources.

The purpose of the court is to judge the relative merits of the individual's right to privacy and Google's rights, and Google do not have to do anything until a court has ordered them to. Google is upset because they don't want to do anything with courts at all.

Their solution is to they hire a raft of PR guys to spin this story as much as possible to confuse people in to thinking that this means people like Peter Sutcliffe can be erased from the internet. This form and the 12,000 "requests" that it has received are solely designed to give Google's PR people a story that they can spin to newspapers and confuse people further.

So far, they have had to remove one link to one article, containing out-dated financial information, when you search for one guys name, so that the guy can stop having it included in his credit score. That is it.

Poor google, how will they cope.

Re: Re. trojan$

He's only provided anecdotal evidence, but you are being a massive dick for not understanding that not only is he 100% absolutely right, but that that it is a well known fact that as you place higher voltages through an IC or use it at higher temperatures, the shorter a working life that IC will have.

However, a GPU will be sold to work at a certain spec for a certain period of time. It might be rated for 3 years warranty. Using it at 100% utilisation for 3 years should not mean it would stop working after 3 years, but it might mean that it stops working after 4 years instead of after 9 years with modest usage.

BRITS: Wanna know how late your train is? Now you can slurp straight from the source for free

Tom 38
Silver badge

Re: Good Thing (TM)

Trains aren't that shit to be honest. I spent 5 years commuting by train, for 4 hours a day. Occasionally something really unexpected happens, and you get stranded for 2-5 hours in the middle of nowhere - that happened to me just once.

Infrequently, the first branch service would not show up, because the train didn't end up in the right place the night before or overrunning engineering works. Branch services definitely aren't as reliable as main line services, but if your main line train is delayed, they'll often delay the departure of the branch line to compensate.

The only thing bad about the trains are the cost and the overcrowding. The former is only necessary due to the latter. Everyone tries to get on trains that arrive between 8 and 9 am, with later trains basically deserted.

I suspect that it is all rigged so that commuters all travel at the expensive time - there is no significant benefit to taking a later train if you travel most days, the season ticket is the same price. This then constrains the off-peak price, because if they lowered it too much, commuters would travel later and buy individual day tickets (which would, incidentally, solve those overcrowding issues on the trains and tube and lead to a more even flow of passengers throughout the day, but hey, less money, so lets nix that one).

Here's my list of desired features from the train companies:

1) Flexible season tickets - I want to buy a season ticket of 30, 60 or 90 non-consecutive days, especially as I am expected to work from home two days out of every five.

2) Flexible walk up pricing on non-peak trains - if the train is empty, it shouldn't cost you more than £1 to ride it.

3) When I give you £6000 for a years season ticket, and in return you give me a machine processable token to get through entry gates, then the token should be durable and resilient. A paper card with a magnetic strip that lasts 2 months tops (1 month if its also a tube travelcard) is not sufficient.

3a) Stop making me carry my photocard, embed it in the ticket

Re: Danger!

I get it perfectly well - the law says that when you accidentally give access to information to someone not authorized, you're not publishing the data, and when the unauthorized person access that data it is unauthorized access to a computer.

The law is a fucking ass. Putting something online is publishing, allowing someone access to data is authorizing them to access it. The law says that these things are not publishing nor authorization, and so the law is - obviously - wrong.

It does not matter that you did it accidentally - don't have bad processes.

It does not matter that the "someone" is an unidentified anonymous internet user - that is who you authorized to access it.

Businesses and courts don't like this because it made their lives difficult, so instead they made the law difficult. Much better to redefine what "published" and "authorized" mean in newspeak than to properly secure your data.

Anyway, the whole point of this was not about the vagaries of URL manipulation - TFA suggests you can infer information from your competitors, and indeed you very often can.

Just be wary when you realise you can extract a great deal of information from them and think about the legal implications before you fire up a script to capture all that lovely information - it might be illegal to retrieve the information they have "published" and "authorized" you to access, for the reasons listed above.

Re: Stop gap

This isn't virtualisation, it's emulation. The linked PDF does explain:

While virtual machines (VMs) are useful for desktop and

server computers to run apps intended for one platform on

a different platform [36, 44], using them for smartphones

and tablets is problematic for at least two reasons.

[…]

To address these problems, we created Cider, an OS com-

patibility architecture

This is how FreeBSD's linux emulation works, the linux binary is linked to it's linux libraries, and a special rtld that maps any linux syscall (which would be handled by the linux kernel) to an equivalent BSD syscall.

For cider they have to do a bunch more work to make API stubs for iOS user-space libraries, but the premise is identical.
