Amazon triples profit to $11.2bn, pays ZERO DOLLARS in corp tax – instead we pay it $129m

Re: Make it attractive to pay tax

No, VAT is still payable. Amazon can avoid corporation tax, it can't escape VAT.

Object-recognition AI – the dumb program's idea of a smart program: How neural nets are really just looking at textures

Persona

Re: Surprising...

Looking down the microscope at a slide you get a largely 2D view of the object and rarely use binocular microscopes. Shape recognition works.

A person looking at a cat directly gets 3D information and when it moves your brain integrates it all into a cohesive 3D cat. Once learnt you can infer the 2D outline of a cat in any position so recognize the 2D image as a 3D cat. By training recognition systems with libraries of 2D images the systems have chosen to ignore the wildly variable 2D outlines that result from the different positions of the 3D object and concentrate on the more consistent textures …... which sometimes give horribly wrong results.

Mini computer flingers go after a slice of the high street retail Pi

Re: Mini computer flingers

Intel started with 4 bit microprocessors and the package only had 16 pins. A Xeon Phi with 72 64bit cores in a package with 3647 pins .......... is a lot bigger. Way to big to still call a microprocessor.

Sure, you can keep Grandpa Windows 7 snug in the old code home – for a price

Re: Why is Windows monolithic?

40 years ago computers normally had reset buttons on the front panel. CP/M and DOS and all the "home" computers that preceded them lacked an O/S capable of pulling execution away from a looping bit of code. Even a PDP 8 had a halt switch.

Crypto exchange in court: It owes $190m to netizens after founder 'dies without telling anyone vault passwords'

Re: Tangible value of currency

That's not a good comparison. Fiat currency has value and need because of the government behind it. It levies taxes that must be paid in its currency and it pays out in that currency. The currency then becomes a representation of the underlying asset value of the country. This "generally" makes for a reasonably stable currency which can be valued then traded against fiat currencies of other nations. This is utterly different to bitcoin which is not a currency. A more appropriate analogy for bitcoin would be a limited set of baseball cards. When the fans want to buy them the price goes up, and when they want or need to sell them (perhaps to pay a tax bill) the price goes down. Even that is a far from perfect analogy as a baseball card has a picture on it with some intrinsic value.

N of M key sharing is a feature built into every Hardware Security Module you can buy. I've even used it on two different brands. Don't build it yourself: the cost of failure is too high.

Persona

Re: Lesson for us all...

Your argument would be true if the bitcoins together represented some underlying asset with a tangible value. They don't. The value of a bitcoin is simply a function of market supply and demand: when people want to buy them it pushes the price up and when they want to sell the price goes down. As there is no underlying asset that can be valued independently, there is no true notion of the price being under or overvalued so there is nothing to constrain the price rising towards infinity or dropping to zero.

Re: Why not just

I would consider allowing one of these devices into my home if it had such a button, provided that the button operated by physically removing power to the microphone pre-amp. It would also require an LED on that power line so I could see if the device was capable of listening or not.

Furious Apple revokes Facebook's enty app cert after Zuck's crew abused it to slurp private data

Re: FFS!!

I don't think they deliberately sell the data, but I'm happy to see the evidence to be proven wrong.

As I see it, it's too valuable to just sell as by holding onto it they can continually monetize it with dynamic ads that lets the advertizer select the data characteristics Facebook will use to target the add.

Even Windows 10 can't save the PC market as chip shortages, Brexit uncertainties bite

Persona

Re: Windows 10 can't save the PC market

Windows 10 should have been the solution to exactly what the article was about, namely the inevitability of the market for home PC's evaporating. Their hope was to keep their users by developing Windows phones that felt the same as their Windows desktop at work and also gave them the option to allow their phone to plug into a screen/keyboard to give the productivity when and if required.

The problem was that they came late to smartphone market and missed getting aboard the apps bandwagon. In their panic to catch it they pushed out Windows 10 to phones before it was ready and destroyed the platform they hoped to migrate their users to by making it an unattractive choice for third party phone manufacturers.

Persona

Re: Windows 10 can't save the PC market

Nope. The smartphone broke the PC market. Most of the things that a home user did on their PC, they now do on their phone. The few instances when they need the PC they struggle and do it on their phone slowly and inefficiently because it's not worth the expense of buying a PC to fill those needs alone. Business users need the productivity of the big screen, keyboard and mouse so they are still largely buying PC's though for some job functions the phone is sufficient.

Whats(goes)App must come down... World in shock as Zuck decides to intertwine Facebook, Instagram, WhatsApp

Persona

Re: Damn

Quite possible as the US has a low penetration of WhatsApp. For the 18-29 age group its 30% and for the 30-59 folks it's 25% both of which are dwarfed by Facebook messenger.

It's the network effect. You use what your friends use, and they use what their friends use. For the US this means a big dominance of Facebook messenger and for the UK it's WhatsApp. It is however possible that you are in an isolated social bubble so don't come across people using the regionally dominant messenger even though they probably do ...... just not with you.

I solved this problem 20 years ago, by buying a single roll of Izal hard toilet paper. It's truly horrible stuff that I remember using as a boy on my Grandparent outside loo.. When supplies get low I see this roll sitting at the back of the cupboard and the thought of having to use it is so bad it sticks in the mind for days ensuring that I remember to buy some nice modern comfortable paper. Consequently I have never needed to use any of the 336 sheets from the 75mm diameter roll....... yes it's that thin.

Encryption? This time it'll be usable, Thunderbird promises

Persona

Re: @AC - How To Do Encryption IN THE REAL WORLD

PKI was invented to distribute symetric encryption keys over an insecure channel. The problem with PKI's is that everyone needs to use the same one (though bridging is possible). Both national governments and financial instututions wisely see no net benefit to prioviding large scale PKI's, so they are fragmented. You also need to trust the PKI to correctly distribute the public key. It gets really messy when you start factoring in key expiry and revocation and people forgetting their private key. These complications have limited it to small scale deployment, and this hasn't improved in the last 20 years.

A few reasons why cops haven't immediately shot down London Gatwick airport drone menace

Re: Send in other, bigger, better armed drones?

No. Keep it simple. Send up a unarmed drone with longer flight capacity to follow it home. Follow this up with a visit from plod to collect the forensic evidence (i.e. a drone with lots of fingerprints and DNA inside and out) and/or nab the perpetrator.

Re: Beer in the Sodastream?

Blue Nun is interesting stuff. Just don't drink it. The prototype for Le Piat D'Or red wine was made with Blue Nun and red food colouring as this would "appeal" to the regular British consumer in 1974 who wasn't quite ready for real red wine. They then went to a French wine producer and asked them to make red wine that looked and tasted that way. It was very popular in its day thanks mainly to an attractive bottle and a huge TV advertising campaign.

He's not cracked RSA-1024 encryption, he's a very naughty Belarusian ransomware middleman

Broker

He is simply a broker. There are good reasons to use a broker who has been around awhile and understands the business rather than dealing directly with the end party whom you have no reason to trust. A broker always gets commission for his services either by charging a fee or pressing the supplier for the discount he knows he can get, and often both! As for cracking RSA-1024, the only practical way of doing this is to "obtain" a copy of the private key.

Shocker: UK smart meter rollout is crap, late and £500m over budget

Persona

Re: OK, but why ....

@veti

"Load control? Unless the rollout is even dumber than I've heard, that's not done by cutting off power at the meter. It's done by selectively cutting off individual major loads, usually an immersion heater."

How could it possibly do that? The smart meter in on the wires coming from the company fuses and going into the consumer unit. It's all or nothing. You would need a smart consumer unit to selectively cut power to individual circuits.

All a smart meter can do (in the future) is allow power to be bought with an expensive high reliability tariff or a cheaper low reliability tarif that gets turned off when power demand exceeds supply.
