Re: Not sure of the math

"At 0.3c, plug it into the kinetic energy equation"

You are quite correct with the calculation but it's worth noting the relativistic energy is slightly higher even at 0.3c - at higher velocity it will be much higher.

e.g at 0.8c it's ~2.8e18 J

Re: LEAVE EU would actually STAY in the EEA

"I think maybe there are several reasons that Switzerland gets a special seat at the European table"

I think if you read the BBC article you'd find they don't think they have. Our conditions might be even worse - who knows. But if you look at the list of conditions I don't think many of people here would prefer them to our current status.

"Add to that the 'convenience' of their secretive banking system."

No so secretive these days. I have to give my Swiss bank permission to share data with HMRC and that's on a current account.

Re: how do you measure a change of 1/10,000 of a proton diameter with a laser?

The moon is having a measurable effect by gravity on our planet but any gravitation waves produced by the moon are miniscule.

" but even so 140 hp is one heck of a motor."

I'd imagine it's about high-ish average-ish even in the UK . But more to the point where are they going to get 500 kW of battery power that will get them a reasonable range as well. It's about 5/6 Tesla batteries at ~500kg each for about 1 hrs duration flight ( I know doubtless cruise will be much lower consumption )

Re: Why put it all below water?

"I might be wrong, but if the servers are in the sea there is no need to pump any water anywhere so they save even more energy."

Question is how much would you save compared with the extra costs of engineering for such an environment, maintenance and upgrading.

I'd have thought installing in the base structure of a wind turbine would be a better bet.

Five technologies you shouldn't bother looking out for in 2016

Chemist

Re: Five technologies you shouldn't bother looking out for in 2016

" Thank you for proving my point that no one really needs it to be Linux."

Apart from a few specialist programs that might well be true - it's just that some of us find it a far superior environment. After all I have to go to the 'trouble' of building my own desktops aand servers and hunting out laptops that are OS free and then installing LInux and it's all still worth it for me.

Most people don't need Windows in that to quote LucreLout below "but then, 99% ish of home users aren't doing serious programming; They aren't even building Android fart apps, they're just browsing the web."

(Not my figures and I don't happen to agree either.)

I repeat - why would you want everyone to use Windows ?? What's it to you ?"

Re: Five technologies you shouldn't bother looking out for in 2016

"You can't understand the very simple fact - is that Linux Desktop is a collection of incompatible libraries, wildly and poorly designed applications that do not follow any UI concepts and do not work with each other"

As I've used Linux since 1996 I don't need anyone to give me a lesson. I use it all the time for everything both professional and personally - I don't find the problems you seem to think exist - all the applications I use cut & paste fine together - partly because I use the same desktop environment and partly because I make sure I use the best applications for my purposes. I had to seriously try to think of an example that didn't work - and all I could think of was an old vector editor I used until a few years ago when I started using Inkscape.

Do you really imagine having worked all my life in a high-powered scientific environment I'd be wasting my time fiddling with something not fit for purpose. I'm perfectly happy using Linux, so are many other people so basically mind your own.

I repeat - why would you want everyone to use Windows ?? What's it to you ?"

Re: Five technologies you shouldn't bother looking out for in 2016

"Thanks, you just proved my point that noone in the real world needs Linux on desktop."

Your view of the real world obviously is at odds with mine.

Apart from the scientific angle I use Linux for everything I do. RAW photo development/editing, video editing, PIC programming (MPLAB works perfectly in WINE) and now there is a Linux version anyway, and all the usual stuff - except I don't use cr*p like Facebook (sob !) but e-mail, browsing, Google Earth, LibreOffice, VirtualBox and lots of other stuff.

In fact I can't understand your problem - why would you want everyone to use Windows ?? What's it to you ?

Re: Five technologies you shouldn't bother looking out for in 2016

"Anyone non-IT professional who uses Linux desktop does not really need any desktop at all"

What an extraordinary claim. Almost all the people I know personally who use Linux desktops are NOT IT professionals but are scientists & academics. The reasons are complex but the simplest is that a lot of scientific software was written for UNIX and has been ported to Linux. The subsequent ports have been improved, extended and adapted to newer hardware. The other major reason is the availability of compilers/interpreters for a range of languages as a lot of scientific software is written/adapted by scientists for peer consumption.

If you doubt the existence of commercial software of a highly complex nature for Linux can I suggest :

As part of the plot he offers the public votes on all issues, the Post Office quadruples in size and all voters have to toil over large numbers of ballots.

" prior to X.org the truth is that it was not even remotely usable."

Strange then that I and my colleagues (200+) were running all sorts of commercial and in-house scientific software on dual Xenon workstations with 3D graphics hardware using RedHat Linux around that time.

Re: Remind us again...

"Quite. Isn't it about 1.5% or something? Which is somewhat larger than 80's coder thought."

And may I remind everyone almost all those 1.5% have chosen to install Linux. Given that ~80% people don't know/care and that most machines (99% ??) are purchased with Windows installed and many have no option anyway because their company insists on Windows anyway 1.5% is a really large percentage.

"they had no drivers for my Nvidia 970 leaving me with software rendering "

Sorry don't have too much time to go into this at the moment this but there are Linux Nvidia drivers available for the 970 - http://www.nvidia.com/download/driverResults.aspx/77844/en-us

What is likely to be the problem is that (I'm not a Mint user) the driver needs to be added after install via probably an additional repository ( certainly that's what I've done with OpenSUSE but I've not needed to install on a system with a Nvidia card for quite a time). I note you've also had problems with NVidia on W10

In general, I'd also suggest trying a few live-CDs just to see which you prefer.

Re: Flipping your mind

"If the black hole boils itself away over billions of years at some point there should be a point where the gravity pull of a black hole collapses such that light can escape and therefore you should be able to "see" what's left inside?"

My understanding is that as the black hole shrinks the rate and energy of photon production increases until finally it disappears in a burst of gamma radiation, at which point you can 'see' inside but nothing is there by then.

Interesting - Douglas Adams must have been more prescient than I imagined as he introduced them in ~1978 long before Google was incorporated. (Note NOT before Microsoft was though )

This quote from ~~1984 :

(You know how I hate those smug Sirius Cybernetics salesmen: slick-suited creeps of the cosmos, flogging computer operating systems that crash more often than air cars built on the Friday shift. They have persuaded the Universe that if it doesn’t continually upgrade itself at enormous expense, it has no right to call itself froody.

Re: Who owns my computer?

"I tried Linux around 2010 along with the (then) utterly busted 'Open Office.' It was a disaster!"

I'm glad you are now sorted but I can't have everyone assuming that you are typical.

I was using Linux for serious research involving expensive software and state of the art 3D hardware in ~2002 without sig. issues and indeed personally I've been using it at home since the mid-90s - since the late 90s it's been straightforward to install on every bit of hardware I've tried and has given very little trouble apart from temporary problems with e.g some wifi adaptors. This is mostly with SUSE and OpenSUSE. Not used Windows since ~ 2006 at home.
