Renewable energy 'simply WON'T WORK': Top Google engineers

Re: reducing energy consumption

If you can do simple arithmetic you can see that nuclear is the only safe, green power source. Sadly, greenies can't.

Encouragingly, there's a growing minority who can, such as Patrick Moore (the environmentalist, not the late astronomer)

Ofcom snatches 700MHz off digital telly, hands it to mobile data providers

Wilseus

Re: Twisted and skewed

What's more, most ariel filters that have currently been fitted and are being sold right now, reject anything over 800mhz. So essentially we will all need new filters too!

Most *aerials*, even many wideband types, reject everything much above 800 MHz, never mind any filters you may have fitted.

Re: I want it

as a Linux user I held off from taking part. Getting E:D to run under Linux was probably going to be a bit of a job, so I was going to wait until it was released and then see if it was possible to get Wine to get it to run.

Same here.

Want a more fuel efficient car? Then redesign it – here's how

Wilseus

I used to own a Citroen BX and many body panels on that were plastic, including the bonnet. I think the whole car weighed only about 800 Kg. Mine was a 60 bhp diesel, was very good on MPG and was quite nippy. I never drove one of the 160 bhp 16v ones but they must have gone like stink!

Mobile coverage on trains really is pants

Wilseus

It's pants now, but didn't used to be

I've been commuting on the train between Northampton and Watford for several years now. I own a non-4G Moto G, and while my T-Mobile/EE 3G signal was patchy in places such as Tring*, up until the last few months it was usable for most of the journey. However now it's almost completely useless and as a consequence I've given up browsing and I now read a newspaper instead. Even at a major station such as Milton Keynes, I get nothing. I presume that this deterioration in 3G reception coincided with their 4G rollout.

I've tried to phone up EE to complain on more than one occasion but surprise surprise, I've never been able to get through to speak to someone.

*Oddly enough, Tring station, the one place that there was never any signal at all, is now one of the few places on my journey where I can, briefly as the train passes by, actually download a web page.

maybe Webb or the one that follows us will be able to produce images like that.

Sadly not, it's much too far away for that, and even then there would very likely be dust clouds in the way. We can't even see into the centre of our own galaxy at visual wavelengths because of those.

Is that a 64-bit ARM Warrior in your pocket? No, it's MIPS64

Wilseus

Re: RISC, not IRONIC

"And ARM's predicated instructions (dropped in the 64bit, rather unavoidably, too much state to carry around)"

Yes, I deliberately didn't mention those because I'm not sure they actually help with code density.

I haven't investigated CoreMark, no. I'll have a look.

Re: RISC, not IRONIC

Coming from a background in ARM, MIPS and i386, I think that while the code size is not much of an issue in some ways, it's very much an issue when you take instruction cache into account. If the MIPS code size is twice the size of i386 then compared to the Intel chip, the instruction cache size is effectively halved.

I realise this is veering wildly off topic, but I'd be interested to see how 32-bit ARM compares to MIPS in this respect, given its implicit shift instructions and multiple load and stores.

Dolby Atmos is coming home and it sounds amazing

Re: I've seen a couple of films with Atmos

"My Onkyo must be ooo 4 years old now, it wouldn't break me to replace it. But here's a thing.. the speakers I use are well over (and I mean WELL over) 20 years old."

Same here, except mine's a Yamaha. I'm not usually into these new gimmicks, 3D for example doesn't interest me at all, but I'm going to be watching Dolby Atmos with interest. It'll not be expensive, you'll be seeing it in entry level amps eventually.

Re: Mine is great

The Nexus 5 also has 90 degree polarization, so the screen also can't be used in landscape with sunglasses on :-/

You could get round that by taking advantage of quantum weirdness and placing a polarising filter, rotated by 45 degrees, in front of the screen :)

We need to talk about SPEAKERS: Sorry, 'audiophiles', only IT will break the sound barrier

Wilseus

"HiFi is purposefully designed to have a flat response so that it plays back exactly the source material"

Some HiFi is. But some manufacturers, notably Linn, consider the pace, rhythm and timing of music more important than a completely flat frequency response. Consequently, many of their speakers aren't exactly the last word in HiFi but what they do have is the "boogie factor" and surely that's what's most important. Their Keilidh model was a good example of this.

Shine on you crazy diamond: Distant dwarf may hide space jewel

Wilseus

Re: I'd love to know...

I was thinking this too, I guess they must be comparing the white dwarf's surface temperature to the temperature of the Sun's core, but that's kind of reasonable: a white dwarf IS essentially the core of a Sun-like star, after it's turned into a red giant and gradually lost its atmosphere, so the very youngest and therefore hottest white dwarfs would presumably have a temperature in the order of megaKelvins.

Also, 15 million K for the Sun's core is not exactly speculation, we have very good reasons to know it's roughly that value: amongst other things, the nature of the neutrinos that we detect coming from the Sun's core tell us a lot about its temperature. (In fact, a while back, scientists were confused because the neutrinos seemed to tell us that the core was cooler at around 10 million K, and yet we knew for other reasons it should be higher, but this mystery was solved when we discovered that neutrinos can "oscillate" by changing their "flavour" as they travel to Earth.)

Four-pronged ARM-based Mac rumor channels Rasputin

Wilseus

Re: Misc Musings

> A friend worked at Apple back in the day, and his group produced a IIGS followon that was ARM based. Ran all existing (6502-based) IIGS code. Snappier GUI than the then-current Macs, cheaper, oops! So it was "gassed".

That doesn't surprise me one bit. Their early familiarity with ARM also makes it even more interesting that after the Power Mac was released, their marketing department "forgot" that it wasn't the first RISC home computer.

> If you-all think that "just re-compile" is so easy

I certainly didn't think that! In fact I am working on this sort of thing right now, porting a large amount of x86/ARM targeted C code to another CPU. Setting up a cross-compile environment is far from easy, even if the tools you are using actually support your target CPU properly (In my experience, "experimental" invariably means "unusable.") and it never "just works" even when you eventually get the damn thing building!

Re: ARM vs. x86

Just to add to what I said earlier - and apologies for taking this a little off-topic - but this link will help illustrate just how much of a cluster**** x86 really is. Be warned, it's not pretty!

In contrast, you can summarise the entire instruction format of a typical RISC processor in just one page.

ARM vs. x86

This is one of the most interesting topics I have seen for quite some time. I remember Acorn's glory days when the ARM beat the pants off the Intel chips of the day, which is what the original chip was designed to do.

Common sense would dictate that any chip supporting any sort of RISC instruction set, containing the same number of trannies (put to good use) as a modern x86 chip would thoroughly and convincingly trash the x86, because it has to dedicate so much silicon to sorting out the hideous mess that is the x86 instruction set which anyone who has ever dabbled with assembly code will know.

But is this true? Why did so many promising RISC designs that had such high performance (SPARC, Alpha, MIPS, Power) fall by the wayside? Was it simply market forces, or is the efficiency of RISC systems just not that important, as Intel keeps saying?

Before anyone says it, sticking 32 or 64 ARM cores on one chip might work for servers but won't work for general desktop use, see Amdahl's Law

Why are there still no RISC systems that thoroughly outperform x86 on a core for core basis?

I'd love to see ARM (or MIPS) based laptops and desktops out there beating the socks off Intel's highly-polished turds, but there must be some reason that this has not already happened. I just don't really understand what that reason is.

Audio fans, prepare yourself for the Second Coming ... of Blu-ray

Wilseus

Re: Cuing the obligatory audiophile discussion regarding sample rates...

"Modern music (well, for about the last 15-20 years) sounds absolutely dreadful - not because of sample rates or MP3 compression, but because of the utterly abysmal mastering."

Dave K, your entire post is *exactly* what I have been saying for years now. This is one of the main reasons that practically all of the music I listen to these days is 70s and 80s progressive rock. They're generally not remasters either; I scour eBay and Amazon for second-hand original CD pressings.

It's rather telling that the titles in the picture accompanying this article are mostly titles from that era.

Re: Green electrons

Haha yes, and this is further complicated by the fact that electrons do not travel down the wires instantaneously or even at the speed of light. The electron drift velocity is actually quite small in comparison, I remember calculating it in A level physics and it was in the order of a few cm per second from what I remember, so you'd need to factor the considerable time delay from power station to your house as well!

Neil Young touts MP3 player that's no Piece of Crap

Wilseus

I'm not sure they're barking up the right tree here

Lossless audio is all very well, and it's well worth having these days given how cheap storage has become. However the limiting factor in most setups these days isn't the bit depth, sample rate or amount of lossy compression. It's the appalling mastering of many modern albums of the last 20 years. I've found myself responding to that by mostly buying albums that were made in the 1970s and 1980s. Sadly, many of these originally good recordings have been "remastered" and in the process been ruined by dynamic compression and hard limiting which simply robs music of its soul.

There did appear to be a campaign group (http://turnmeup.org/) highlighting this but it doesn't seem to have had much activity over the last few years and besides I had to blacklist their emails ever since they appeared to have turned over my email address to spammers.

The bottom line is, for all MP3's faults I'd rather listen to a decent recording, properly mastered, as a 128Kbps MP3 than a 24/96 FLAC if the latter recording is a distorted wall of mush with absolutely no dynamics.

Neil Young and co. should use their influence to target this first, IMO.
