Submission + - Volkswagen Boss blames Software Engineers for scandal (

hattig writes: Today VW's Michael Horn is testifying to Congress. A choice quote — "It's the decision of a couple of software engineers, not the board members," says VW US chief Michael Horn to Congress.

In addition, 530,000 cars in the US will need to be recalled for significant engine modifications, rather than a software fix. Only 80,000 Passats are eligible for the software fix. There is no word on the effects these modifications will have on the cars' performance, fuel consumption, etc.

As suspected from early results yesterday, the takeaway from Morrison and Evans' videos today seems to be that while intense cases like synthetic Geekbench tests designed to push devices to their limits can reveal significant differences in battery life between devices using the two chips, real-world impacts are much smaller and are likely to be unnoticeable to many users.

Then GIF is pretty much the worst encoding mechanism to use. Yeah, I know it's "art" or "pretentious wankery", but it's a poor showcase of technology.

Here's the Amstrad CPC 464 BASIC version (I should RENUM it). This has far far far denser information encoding. Yeah, I know the font is different. Maybe the font is the entire point of this piece of art.

Fact is that chip and pin has fraud at around 0.7p per £100, and other methods have about 7.5p per £100. It's far far safer.

Just because someone doesn't understand how it works and rants online doesn't make it a valid resource to link to.

If you write your pin on your card, you are a stupid idiot and deserve to lose your money.

Referring to something like this?

Which is odd, because for Cardholder Not Present, you need to know the card's house number and postcode, as well as the CVV, for the transaction to be approved. That was put in place in the UK about 12 years ago. I know many online retailers only require the CVV once when registering the card (Amazon, Paypal, etc), but you would then also need to access the attackee's amazon account, change the delivery address ...

And for cloned cards, you need to know the pin.

Something isn't right with the story.

You can still be mugged for the card.

But the mugger will have to force the pin out of you. And hope you don't cancel the card before they get to use it.

Or forge a signature, as this system appears to be implemented in this case - I presume the signature is encoded on the card chip and only visible to the cashier? Dunno how that's meant to work if the user can forge the signature from a physical signature on the card.

A retailer can tell you they're charging $10 but actually bill $1000.

How hard is it to verify the amount on the screen when tapping in your pin? Or is the American system done by the cashier entirely, because it's too hard for typical Americans to cope with?

The cashier should have checked the signature on the paper, against the signature on the card. It's to prevent card theft purchases.

Something the contactless payment system completely bypasses, unless you are unlucky enough to get asked for a pin on your contactless purchase. However as there is a limit (£30 UK) you might get a free lunch, some beers and a couple of movies before the card is cancelled, but not much more.

At least chip and pin is something you have (the card) and something you know (the pin), which is fairly reasonable. Since introduction, card fraud has dropped massively in countries using it. I don't know what contactless has done for these figures however.

So he is a raving racist lunatic?

First warning sign - can't discriminate between immigrants and refugees.

Second warning sign - totally incorrect about immigrant benefits to societies, because immigrants provide a net benefit to their host economies.

Obviously the license change is not enforceable, as it's totally racist, but I do hope that all researchers stop using this software.

I would also hope that this guy is done for hate speech in the near future, after reading the article. He's a bona-fide nutjob that would appear to be on the verge of a terrorist act against those his discriminates against.

You'll have traded in the car for a newer Tesla by then.

And the sap that buys the second hand Tesla from Tesla will likely get the same guarantee.

The supercharger network is a classic sunk cost once installed (and Tesla are installing their own solar farms too IIRC to reduce or negate their electric bills) that has low ongoing costs, so free electricity isn't a massive burden for Tesla to have.

If flying is too expensive, I guess a Tesla is going to be too expensive too...

But yeah, if you are one of the few people that do this, then maybe a Tesla isn't the right car right now.

This is also another reason why I think that Tesla really should concentrate on the UK and Europe more, as it's very rare that people do such long journeys (apart from the EU-wide festival goers that drive from England to Slovenia for obscure heavy metal festivals).
