The other end of the telescope: Intel’s Galileo developer board

Re: Review or plug for intel?

That's good to hear–thanks for the update.

Review or plug for intel?

The article begins with the word "Review", but there is precious little evidence of this. Did the reviewer actually try to use this board or has all the information been extracted from sales literature and online articles?

The Arduino platform is about doing things. I'd like to know how this board measures up when it comes to interfacing with the real world before I part with this amount of cash. I can get a lot of Arduino Uno clones for the cost of this board.

Tech titan Bill Gates: Polio-free India one of the 'most impressive accomplishments' ever

The Gates Foundation

Declaration of interests: Some of my research is funded by the Bill and Melinda Gates Foundation-on the water side rather than the vaccination side

Top marks to the anti polio team at the foundation and the other NGOs that have made this possible. Hopefully this will help improve trust in the places where it is proving difficult to get the vaccination programmes going.

I also hope that some of the commentards above will take the trouble to find out about the work of the foundation. Once they have done that then hopefully they will find out a bit about population growth which is currently been driven by better health care which means that we have more over fifties than ever before, not by the birth rate (which on average is about two children per family)

Beauty firm Avon sticks spike heel into $125m SAP-based sales project

how does it compare to...

I have managed to avoid SAP so far. My current employer uses Agresso which provides an awful user experience and the last "upgrade " took a week during which no orders could be made. How does SAP measure up to this?

Re: No chemists here

Its not a war over pronunciation - the word is spelt differently on either side of the atlantic. IIRC the discoverer of aluminium/aluminum changed his mind on a voyage from Europe to the States. Due to the timescales that information travelled at back then, the aluminium version had stuck fast in GB by the time he got back to this side of the pond.

Sony PS4 SHATTERS UK console sales SPEED RECORD

Re: Look at the profit...

Infoscout is an internet startup that produces its figures based on crowd sourcing and other weird and wonderful metrics. It'll be interesting to see if these figures stand up to scrutiny or it turns out that ps4 owners have got better things to do than tell the twattersphere that they have just bought one.

I own neither a xbox or a ps of any kind. I wish both well in this fondleslab dominated world...

Will no-one think of the children? Re: It's the tip of the iceberg

If the budget phone manufacturers go to the wall then who is going to employ all the children who work in the sweat shops putting them together?

Cheap as chips?

Out of interest, how much do chips cost in the vicinity of Reg HQ? Round here £1.50 gets me more chips than I can eat.

£100 may be good value for a reasonably specked droid device, but cheap as chips implies to me that folk with ordinary income levels wouldn't bat an eyelid if it were lost. I for one would be a bit annoyed (to say the least) if I lost that much money.

Whilst I think of it, why has nobody picked up on the assualt [sic] in the caption?

Wolfram's new equation: Mathematica+RPi=child geniuses everywhere

Stop

A programming nightmare

Mathematica is a truly weird programming experience it is only tangentially related to more standard programming systems. Learning Mathematica will be of very limited use when it comes to learning "proper" programming.

Brit graphene maker poised to go public: Yes, wonder stuff WILL float

phy445

That's not graphene!

Graphene is one atomic layer thick. When there are multiple layers it becomes graphite - the stuff that makes pencils work. This stuff might be easier to make, but its properties are nothing like those of the real thing.

Secrets of Apple's mysterious Arizona sapphire factory: Our expert whispers all

phy445

What about the reflections?

Sapphire produces far more reflections than glass. For fancy camera lenses and watches anti reflection coatings are used. The trouble is these coatings are very soft and will soon be wiped off a fondleslab. It will be very interesting to see what Apple do about this...

Surface 2 MYSTERY: Haswell's here, so WHY the duff battery life?

Could MS be so firmly embedded with the security services that windows eats battery sending logs of all that you do back to the mothership?

Samsung touching up ROUNDED, CURVY plastic enhanced MODEL

Re: Once upon a time......

Need to interject with a bit of materials science here. Gorilla glass is not significantly different in hardness to other glasses. Where it wins over ordinary glass is in its resistance to cracking - yes I am being serious. I know there are lots of tales of how easily these screens break, but if were made from ordinary glass then they probably break in your pocket.

Glass breaks really easily because tiny cracks in it surface open up easily and this process gets easier as the cracks get larger. Gorilla glass and related materials (Apple uses something similar, but not Corning's ape themed product) is specially treated so that the surface swells and closes up any cracks in the surface - this makes it much harder for the cracks to spread. If enough damage is done so that the crack is larger than the thickness of the swollen region then the crack will spread like wildfire.

Mines the white lab coat in the corner...

Stallman's GNU at 30: The hippie OS that foresaw the rise of Apple - and is now trying to take it on

phy445
Alert

Whoops

I hit what I thought was the read comments button expecting to be treated to a plethora of sage words, not realising that there weren't any. Whilst I'm here I might as well make a comment.

I'm with Stallman most of the way. Open source software is a good thing. It helps drive innovation. However, I am happy with companies such as Apple and MS not releasing all the source code to their operating systems. I tend to look on devices (Apple in particular) as hardware and OS combined. As long as I have got the APIs then I can produce code for these systems.

I shall now retire a safe distance and whatch the fireworks begin.

Boffins demo new holo storage using graphene oxide

phy445

Read the paper

The paper does not discuss these results in terms of holographic mass storage as implied by the El Reg story. The paper discusses the use of the technology for security markers - this is really should not take too much to develop it. A microscopic security tag that requires a femto second laser source to record an image onto will be reasonably hard to forge making this attractive to manufacturers of bank notes etc.

Microsoft: Surface is DEAD. Long live the Surface 2!

Ugly dock

I'm afraid that dock in the first picture is astonishingly ugly. It looks like someone on Hackaday ripped some bits out of an old printer to repurpose as a stand.

I think they have even managed to out-ugly Dyson!

If MS want large numbers of people to part with money for slabs and the peripherals then they need to up the style factor. At the moment the Tesco slab looks better.

"Almost all of this was contained by a backup dam..."

Just been checking the statements from TEPCO. apparently about four cubic meters of the leaked water was contained by the dam. The remainder of the 300 tones of water is merrily diffusing its way through the soil.

Reading the announcements from TEPCO is eye opening. They seem to be reacting to events rather than getting on top of things. They didn't even think to monitor water levels in their storage tanks until this leak was spotted. Not measuring things makes for good plot twists in films like Jurassic Park, but the nuclear industry has no excuse. IIRC there was a leak at Sellafield/Windscale that was't found for a long time because they did't bother to monitor the levels correctly.

Nuclear power, much like communism, looks like a reasonable idea on paper, it just all falls apart when humans get into the equation.

"They always have a back-up"

So just how did this disaster come about? Something to do with the back-up failing I seem to recall.

Z88 anyone?

Surely Uncle Clive's Z88 should be on this list?
