Teen turned away from roller rink after AI wrongly identifies her as banned troublemaker

Re: exhibit ingrained racist assumptions in the design

No, it only becomes racist if different quality of the results is not taken into account.

Dark faces are harder to recognise with light-based photos or video, that's just a fact. If you try to improve recognition of black faces, you will also improve recognition of white faces, the difference stays the same.

Assume that a black kid has a higher chance of a "97% match with known black troublemaker" than a white kid having a 97% match. So far no racism. It becomes non-racist if the software requires say a 98.2% match for black kids and a 97% match for white kids, or whatever the numbers are so that all innocent kids have the same chance of being rejected. It becomes racist if you reject twice as many black kids than white kids.

Re: "If" - Context

I assume “97% match” means 3% of all Americans look as similar or more similar to the photo as she does.

If they had 50 people banned then most people would be a 97% match to one of them.

Re: That's not how they were using it wrongly

FaceID uses distance measurement, basically analysing the detailed shape of your face. Skin colour has no effect on it at all. Demonstrated using some models with an amount of face paint that would have been unrecognisable by any human, didn’t affect faceID.

At a former place, around the time of the millennium crisis, our build system broke on February 2nd, 2000. Some code checked the date and rejected this one. Investigation showed that the date checking code was completely, absolutely broken. It was written in Perl, and it was the kind of brokenness that you could only produce in perl. But - it was never given an incorrect date, and in the past it had reported all dates are fine.

Exercise to the reader: In which way was February 2nd, 2000, different from every single date in the 1000 years before?

gratou, first it's a low end machine. Second, you can get a cheap ten port hub which is plenty. Third, you can get a cheap USB-C hub which _includes_ charging. So you can charge and use two USB-C hubs. Fourth, lots of people don't use a single USB port.

It’s a low-end machine. All the M1s are low-end machines. They are bloody fast low end machines, but they are low end. Apple is still selling many mid-range and high-end Macs with Intel processors. If low-end isn’t enough for you, don’t buy it.

I’d expect a whole range of mid-range Macs in the second half of the year, they should be much more suitable for you.

Re: Good for Bitcoin

Why was that worrying? It would have f***ed up bitcoin completely, which would be good news.

gnasher729 Silver badge

Re: Mining...

No, you are not creating real money.

Bitcoin is like 50 million lottery tickets. Each ticket is supposedly worth $37,000. But there is no cash anywhere. The way to get your $37,000 is by finding some idiot who is willing to pay $37,000 for your lottery tickets.

And these tickets are very hard to forge. There's a known way to forge them which means spending about $20,000 or so on electricity in countries where the cost of electricity is subsidised to let people live better, like in Venezuela. That's why when you mine bitcoin in Venezuela using subsided electricity, you are effectively stealing from the country, and they put you in jail for it. In the UK, the same electricity costs $60,000 so it only happens when people steal electricity from their neighbours.

But in the end, all you created is not real money, but a lottery ticket where you hope someone will give you money for it.

I remember working at a place with a server where nobody knew what it did, except we all knew its fan made a lot of noise.

Two years after I started, the decision was taken to turn it off and deal with the consequences. We turned it off. The room went silent. And for the first time I realised that my Mac wasn't actually 100% quiet, it's just that I had never heard its fan over the noise from the server.

We never heard of anything failing without that server.

Re: the partial return of imperial measures

10,000 km is the distance from the equator to the North Pole, as measured back in the day. Measurements today are a bit more precise, so just as a day isn't 86,400 seconds, the distance from equator to North Pole is a bit over 10,000 km.

The distance is also 90 degrees times 60 minutes = 5,400 minutes, so the nautical mile is about 10,000 km divided by 5,400 = about 1,852 meters.

Re: Brexit bollocks

A was in need for new carpets around the time they changed from feet to meters. First, the carpet shop had gone metric. Their prices where not pound per square yard, but pound per 0.8631 square meters. Seriously.

Next, I needed a carpet, 13 foot 11 inch long. The pimply youth at the shop pulled out his calculator and typed 13.11 * 0.3048 = 3.9959 meters. Lucky enough I know that 13 foot 11 inch is just a little bit less than 14 foot which is more than 4.2 meters. Now I'm older and nastier than back then, I would him take his calculation, and write down "customer ordered 13 foot 11 inch" on the order paper. And wait for the carpet fitter to arrive with a carpet that is 20cm too short for the 13 foot 11 inch room. With proof that I ordered a carpet that fits.

Pakistan's Punjab province tells citizens to get jabbed or have their SIM card blocked

Let’s say the government achieves 100% vaccination. The result will be that 100% of infections and 100% of deaths are vaccinated people.

60% deaths in fully vaccinated people is not unlikely. Consider that those most at risk have the highest vaccination rate, and vaccination doesn’t work 100% if the time. So the unvaccinated will have more cases, but since they are mostly lower risk the high infection rate doesn’t translate into a high death rate.

Re: Makes no sense

You can easily get a list of say everyone registered to the NHS who hasn't been officially vaccinated. And you could easily give that list to BT, O2, EE etc who are all supposed to know who has bought SIM cards. And it would be easy enough to black all those SIMs.

If you instead hand over a list of everyone vaccinated, you kill all the SIM cards that were bought under false names as well.

Re: Like Liam Gallagher says...

You get to do it again once all the criminals have forgotten about it.

And an important thing is that if criminals fear that their "encrypted" data can be read by the police (there have been two completely cracked "real" applications and now this trojan), and that makes them hesitant to use encryption apps, that slows the criminals down, which is also a good thing.

On the other hand, when I hear politicians calling that end-to-end encryption should be removed: For law enforcement purposes, I really hope that they play a game where they give Facebook, Apple etc. a bit of hell but not too much, while at the same time working with them to actually get that "end to end encrypted" data.

On the other hand: Priti, I have nothing to hide, but my data is none of your f***ing business, and I don't trust you further than I could throw you and your whole family.

That's absolutely brilliant. The drive runs faster, therefore it can be completely tested faster, therefore production time and cost goes down. Pure genius.

Today I shall explain how dual monitors work using the medium of interpretive dance

Re: Laptop + Monitor = two computers?

I always thought that for dual monitor users, Apple should sell monitors that look exactly like their iMacs. Maybe with a small marker somewhere. Which would look good if you want to have two screens, which would let you pretend you have an iMac when you have a MacMini, which would let you pretend you have a Mac when you have a PC - and which would confuse the hell out of some people.

Maybe where other monitors display "no signal" it should display "this is a monitor, not an iMac".

You got this completely wrong. _Every_ copyright holder can sue over license violations, in this case both FSF and Apple could sue. Even if one of them didn’t want to, the other could.

So there is a thief. He is photographed, and he loses a forged library card with his photo and someone else’s name. What would you expect the police to do? I’d expect them to check out the person whose name is on the library card. With the library card or a copy in hand.

“It’s not a valid ID” is a ridiculous argument. If you want to catch a thief, you use anything you can. “They conveniently deleted the picture” is also nonsense. Nobody claims it was his picture. And I assume the thief had long been convicted, no reason ans possibly illegal to keep his picture after that.

Here’s the worst case that I can think of: You have a server with multiple users, all properly separated, with no internet connection, so even malware couldn’t spill any secrets.

One of the users is malicious and _has_ an internet connection. The other users run apps that are not protected from each other. If I can install malware on one user’s account, that malware can transmit any data to the malicious user, and the malicious user can send it to a server.
