Microsoft's Windows 10 Workstation adds killer feature: No Candy Crush

Re: A thought.

It means 4 physical processors rather than 4 cores.

IIRC the normal editions of Windows 10 are limited to Dual Sockets (2 physical processors) aren't they?

Windows on ARM: It's nearly here (again)

And only the user parts of the code will be emulated.

Any Kernel calls will call the native ARM code in the OS.

So I guess it depends what your app is doing as to how fast it will run....

Re: @tim99 - Unions

Jubilee and Northern lines have also been automated, driver has to open/close the doors and then press two buttons and hold them to tell the train to start.

Trains can run ~50m apart at 67mph...they are talking to each other and the control center all the time. The pair of red wires running down the line that cross every 25m are the signalling system lines.

The system is really cool, although if it goes down the drivers can only drive them at <15mph i think...

Central line might be computer driven in the central london section only (I dont think the whole line is automated)....basically all the night tube lines are driven by computer...iirc.

Brazilian whacks Intel over 'exploding' Atom smartphone chips

Mobile CPU would likely throttle far sooner....just because a desktop CPU throttles at 100C doesn't mean the mobile version would reach that.

Also 100C on the die probably wont translate to 100C on the chip package...

Looking at the processor datasheet they are rated for operation in -20c - 85c

PCIe speed to double by 2019 to 128GB/s

Re: R/F Design

Yeah, there is.

I was working for a company on 400Gbps Ethernet solutions last year. The 50Gbps transcievers used on the link (8 are used bonded together) are running PAM-4 modulation. :)

I am wondering how long it will be before PCI-E will require optical fiber. It was thrown about as an idea for PCIe-4 but maybe thats where they will be going for PCI-e 5

Skylake issues

I had a similar issue on an intel skylake system (NUC) which would sleep but wouldn't wake up. I ended up updating the BIOS, removing all the intel drivers and re-installing the latest ones, one by one (Just installing the new ones over the top didnt work).

I would be tempted to put the blame for this one rubbish on intel drivers...

FTDI boss hits out at 'Chinese criminal gang' pumping knock-off chips

Re: Not much sympathy

Lets spin this situation on its head a little.

Lets say a chinese vendor starts selling x86 processors and branding them as "intel processors" with the logo and everything...is that okay?

That is what is happening here, these aren't just people using FTDI's drivers and USB VID, many of the chips feature an FTDI logo. They are counterfeit....

The fact is that if you are a company selling USB chips you aren't meant to use other peoples VID, they actually cost money...

I have designed electronics for years and have used FTDI chips, they are awesome little devices and some can do JTAG, SPI and I2C as well as just being UARTS.

All the risky of being a shareholder...

People don't seem to realise that backing something on kickstarter is more like being a shareholder in a risky venture, except:

- If the company succeeds you get a copy of the product, you don't get to reap the benefits of shares which increase in value.

- If the company fails then you get nothing, while this can be true as a shareholder I believe if a company folds then after debts are paid the shareholders are entitled to something, this does not apply to kickstarter AFAIK.

I think kickstarter have changed their rules recently, you can't simply post blue sky ideas with no proof of concept any more.

Not sure about this

"The usual means of doing this is to confine a superhot plasma of appropriate light nuclei under massive heat and pressure inside a doughnut-shaped vessel using magnetic fields to suspend the plasma and prevent it destroying the structure. Sadly, so far these doughnut "tokamaks" have always required more power to run than they can generate."

I sat through a seminar while I was doing my postgraduate degree at uni, we had a guy from JET coming down and talking to us for 3 hours. The question of the hot plasma destroying the reactor came up.

The fact of the matter is that the thermal mass of the plasma is low despite it being very hot. The actual problem is that if the plasma touches the walls of the reaction vessel it will cool down and the reaction will stop. A single proton hot proton touching a lump of metal will not heat the metal up very much, the proton will just cool down.

Also the reason for building a bigger reactor is that it is easier to contain the plasma in a larger space.

I second point is they tend not to use tritium right now because they want to go inside the reactor vessel to inspect it after the experiments. High energy neutrons can be captured by the walls of the reaction vessel and create radioactive isotopes making it dangerous to then go inside and inspect it. They tend to only use deutrium which doesnt release as much energy.

I do remember they said that the amount of lithium in a laptop battery would power the UK for a year or something ridiculous like that. It was impressive....the commercial timelime they layed out in this seminar was 2030 - 2050 for power being generated by these reactions powering the national grid. We are still a long way off!

Incorrect Statement

"There are flaws: it doesn't remember your ISO choice after the power's cut. And there's no way to reverse your choice other than powering down and re-selecting."

I have owned one of these for 6-8 months. This statement is incorrect. With an image selected and loaded press the jog dial inwards, this unmounts the image and allows you to reselect by tweaking the dial up and down.

Secondly you can organise the images in folders within the _ISO directory, makes it easier to find things.
