It’s Brexploitation! Microsoft punishes UK for Brexit with cloud price-gouging

Steve Todd

Re: Price gouging?

Actually the pound was trading in the mid 1.50's range at the beginning of the year. It fell with the announcement of the Brexit poll. We're down over 20% on the year, and a lot of companies who hedged their exchange rates are going to have to start putting up prices next year as the hedges expire.

Do they still not understand

That market dominance is the important factor here. You can do what you want (within limits) providing you don't hold a dominant position in the market. The moment you do additional rules apply. Since Google have a 75% market share in Europe those rules apply to them.

Brexflation: Lenovo, HPE and Walkers crisps all set for double-digit hike

Steve Todd
Silver badge

Re: Cause and effect?

Unfortunately most international trade is priced in USD. Oil for example, even if it never goes anywhere near the US, is priced in USD per barrel. Most electronics manufacturing happens in China, who wants to be paid in USD. Result: computers and other IT equipment goes up in price.

Walkers may have a hard time justifying their price increase (energy costs will rise, as will the cost of imported potatoes, but that adds up to a cost price that has changed by small fraction of the exchange rate delta), but HPE and Lenovo have a fair point.

Dynamic IP addresses are your personal property, CJEU rules

Steve Todd

Property?

Erm, no. Personally Identifiable Information, yes. The combination of dynamic IP and time is personally identifiable.

The EUCJ is saying that the German government can't require the ISP to store that data as doing so contravenes the EU convention. They do seem to have little idea how easy it is for a computer to combine together the IP and time to link to the subscriber, but that's another point entirely.

Pocket C.H.I.P. makers go Pro with cloud-linked ARM-flexing module for IoT gizmo builders

It has some stiff competition

The ESP32 for example is a twin core, 32 bit SoC with built in WiFi and Bluetooth, but can be purchased as a module for about $6. There's quite a bit of effort to make it programmable from the Arduino IDE (not my ideal choice I'll admit).

Intel is shipping an ARM-based FPGA. Repeat, Intel is shipping an ARM-based FPGA

Steve Todd

Altera have been using ARM for a while

The Cyclone V SE has been shipping with them for a couple of years now. Intel meanwhile have specialist Xeon parts with FPGA fabric on them.

I'd guess that the design work for this was underway pre the Intel buy-out so there's nothing particularly noteworthy about it having an ARM in there. I understand there are specialist Xeon models out there with FPGA fabric also. No real change yet.

EU turns screws on Android – report

Steve Todd
Silver badge

Re: does size matter?

Yes. Once a company reaches 50% or more of a market they are subjected to different rules to prevent them abusing their dominance. As Android constitutes around 80% of the mobile OS market, and the reason for that dominance is down to the size of the Play store, then restricting access to that store unless you follow a set of rules that Google lay down, including insisting on bundling Google apps, constitutes abuse of power.

Roughly 150 tons of fuel are joined to the stack by the second launch. It's that which will be consumed to boost to the specified 6.5km/s transfer velocity and slow down at the far end. It's the size of the fuel budget that gets them the speed, and nothing to date has had a budget anywhere close.

You can do it in a lot less time than that, providing you start out with enough thrust. Elon thinks that the right balance between cargo capacity and safely transiting the distance is 80 days. Add more passengers and it takes longer, less and you can do it quicker.

Video service Binge On 'broke the internet' but 99pc of users love it

Steve Todd

Mr O still doesn't understand net neutrality

The objection is to ISPs giving preferential treatment to services that pay them for the privilege. The reason being this discourages new companies and services as they are unable to compete on a level playing field with the established players.

It doesn't matter that, in the short term, consumers like the product. In the long term it's against their interests.

Re: The software is still there

Talk to nVidia or AMD. Their GPUs are a mix of dedicated hardware and stream processors. No one said hardware could do everything, but there's a lot of performance to be had by offloading the right bits of a task to it.

Re: Nothing wrong with the chips.

@boltar - so you're coding exclusively in assembler and hitting the hardware directly are you? It's the compiler, hardware abstraction layers and library code that slows a modern program down compared to days of yor. All of those are good things in terms of productivity.

Even ripping those out you still have the basic problem that a CPU is designed to execute a stream of instructions, one at a time. There are assorted techniques used to make this as fast as possible, but it's still effectively a sequential process. Hardware is good at tasks that can be either pipelined or run in parallel (or both). If the workload is suitable then hardware can implement it thousands of times faster than the best written code.

Re: I Call BS

You're not getting it. Software will not be going away. What will be happening is that progressively more work will be offloaded to hardware, at least some of which can be soft-configured (which is the whole point of FPGAs). "Patch Tuesday" will contain updated soft configurations as well as traditional code. There's also the matter of the driver stack that connects the software to the hardware.

Is Tesla telling us the truth over autopilot spat?

Steve Todd
Silver badge

Re: Tesla does have a weird reputation...

The problem with the Topgear review was that it didn't represent what happened during filming. I've no problem with them saying it caught fire/ran out of charge etc if that's what actually happened on the day, but to misrepresent events isn't on.

I can understand, in part at least, why they don't like electric cars (the G-Wiz is wretched for example) but Tesla are pushing them to the point they compete fairly well with Petrol (usable range, good acceleration and handling, not a track car), and that should have been more accurately portraid.

Re: I'm not sure how he thinks this will work on an iPhone 6

I'm not sure where you get some of this from but :

1) the secure enclave is a physical not a virtual processor. It has 4MB of its own flash memory directly on the SoC die and runs its own OS.

2) the details are quite well documented, as are the APIs used to access it. See for example https://www.apple.com/business/docs/iOS_Security_Guide.pdf

Re: I'm not sure how he thinks this will work on an iPhone 6

But the key to the data on the flash is maintained in the secure section of the A7 and higher. Once the secure section decides that the maximum number of attempts are reached (it is a separate CPU with limited connection to the main system) it destroys the key and the data is rendered useless. It doesn't matter how many copies of the data you have, the copies still need the AES key in order to read them.

I'm not sure how he thinks this will work on an iPhone 6

With the iPhone 5 and earlier the AES key and try count are stored on the flash chip. Reloading that chip with a copy will reset the count of tries. On the iPhone 5S and higher (anything with an A7 or newer) the key information and count are stored on a secure area of the CPU chip. Taking an image of the flash memory will have no effect on retry counts or prevent the key from being erased.

US Congress blew the whistle on tax-dodging Apple, claims Europe

Steve Todd

Double taxation

That's the reason that companies don't want to repatriate foreign earnings to the US is that they will first have to pay corporate tax on the profits (35% at the moment as I understand it), then any money paid as dividends is also taxed at another 15%. If Congress were to fix that then there would be more pressure from investors to bring money home.

Tesla driver dies after Model S hits tree

Steve Todd

He must have come off the road at a hell of a clip

The Tesla S has one of the best ratings for crash impact out there. If the car went off the road, into a tree, sprayed batteries about liberally and caught fire then the driver wasn't likely to have faired any better in a conventional car.

Looking a little deeper

It seems that the car it's self didn't catch fire. What did were the battery modules that had been flung free by the impact.

The second, and unverified fact is that it was a 2013 model without Autopilot fitted.

Star Trek's Enterprise turns 50 and still no sign of a warp drive. Sigh

Steve Todd
Silver badge

Reactionless drive?

Even were it possible, a craft powered by such a device still couldn't travel faster than light. If the author understands e=mc^2 they should realise that only by converting a body completely to energy can it reach the speed of light. As the craft approaches the speed of light time dialation effects become apparent. The acceleration experienced by the occupants remains constant, but to an external observer it reduces. As they approach light speed their time slows to zero as does their acceleration.

The whole hyperspace/wormhole thing in SciFi is a plot device to get around this problem.

Re: Lost my interest and lunch at C++

OOP isn't about making things faster, it's about isolating functional blocks from each other. C++ will let you write bad code, but done properly it can produce robust, testable code that isn't much slower than raw C. If you think otherwise you're doing it wrong (and yes, I've seen an awful lot of programmers who claim to understand OOP who don't)

Re: Specs

You're confusing servers with workstations. Workstations spend most of their lives waiting for users to tell them what to do. Servers can get thousands of requests per second, in which case the time it takes to transfer the requested data from disk to memory is important.

In case you hadn't figured, this is a server class product (read expensive).

Re: Getting Distracted

The other point is that, as volumes ramp up, the cost per kWh of the battery packs falls. In 10-12 years a replacement pack will be far cheaper than it is today.

Your petrol car also contains consumable parts (oil, spark plugs, filters, belts etc) which are going to add up to rather more in maintainance over that period.

The car was physically able to stop inside of the required distance. The driver failed to spot the issue partially because of distractions, but mainly because the pedestrian seems to have gone out of their way to make themselves hard to spot.
