More evidence that neutrinos are NOT faster than light

Chemist

Re: still quite impressive

On the other hand it's only dense rock because most matter interacts well with it as does light - neutrinos don't which is why the ICARUS experiment used 600 tonnes of liquid argon in an attempt to detect a tiny percentage of the beam and why the many billions per cm^2 that arrive from the sun every second don't pose a significant biological risk. ( although anyone that is worried about that needs to wear a VERY thick tinfoil hat)

Charge of the Metro brigade: Did Microsoft execs plan to take a hit?

Re: Not a chance @vic

If this had been a support forum I would have suggested using a LiveCD to check out the hardware/boot as a first step.

I am sick of unverifiable posters saying things about Gnu/Linux that I know to be not so. The list is almost endless - HD video doesn't work, 3G dongles don't work, hardware-assisted H264 video playback doesn't work. - They all do - not on just one machine but all the machines I try them on.

On another point the consumer as we know buys a Windows machine preconfigured - no option -hopefully all the snags are sorted. If they add any hardware the same problems crop up - many people will have no difficulty, some will. Linux is no different. All the people (mostly seniors) that I've installed Linux for have no difficulty using it

Re: Not a chance @vic

"These days, it's frequently easier in Linux than it is in Windows"

Agree entirely Vic, if you can't get a good Linux distro to install then you are doing something wrong.

Everything I've installed on in the last 5 years (~ 10 installs of OpenSuse) has worked without any problems and that includes all graphics cards, printers, scanner, 3G dongle, USB/serial converters, cameras, firewire devices.

(I did buy a new Canon 55OD where raw mode wasn't supported on the resident version of OpenSuse but the upgraded packages were available and just had to be installed.)

Re: This sounds silly...

I've also got a UBS account. Even if somehow you get hold of a replacement card you'd still need the personal agreement number and 6 digit PIN as well as the card reader.

I'd guess they wouldn't send you a card without the agreement number.

I think it's the best method I've seen although I'm fairly happy with the hideous 20 digit passwords I use for my other accounts.

I don't want to labour the point but on Earth the difference in gravity head to feet is very small but standing in a modest sized centrifuge it would be quite large. Lying down wouldn't stress the bones and muscles.

Re: half gravity = f half the effect?

"were you to build a centrifuge for the 'nauts"

To be physiological and counter the other BAD effects like bone loss and muscle wasting I'd guess that they would need to be able to stand and move around in it. Problem then is unless the diameter is large compared to body length the differential effect* between head and feet will cause problems.

My original post which didn't mention MS (other than in the auto-generated title) was :

{

"If you're change adverse, then perhaps IT isn't the right industry for you."

I want improvement not just change !

}

The comment was a general one - too often mere change is seen as a good thing when real improvement is what most people want.

I'd like all OSs to improve because I don't want any sort of monoculture - I make the choice to use Linux - I certainly wouldn't want to constrain other users.

Death to Office or to Windows - choose wisely, Microsoft

Chemist
Silver badge

Re: Re: Re: Re: "Windows is dead."

I think the problem is the assumption that Linux isn't used much or that users "must still have Windows to be able to survive". You may not know many scientist but of course I do and even in my last company ~200 computational chemists had Unix or Linux workstations without Windows. To get the corporate crap we also had Windows machines.

I also know Linux is heavily used by scientific academics. Good luck with the course !

Re: What are PCs used for?

"Do you really do protein modeling on the train"

Well I used to drive to work - but let's suppose I did have a train journey.

With a laptop and internet connection I could do all the preliminary work, search databases, match protein sequences and set-up initial conditions. I could transfer the data to a compute server or a Linux farm and start the the simulation.

The main reason for a desktop workstation would then be be to analyse the output ( in 3D using liquid xtal shutter specs). This being a few years ago that would rule out a laptop - maybe even now.

@ChrisBedford

Welcome to The Register !

Although I've had an interest in computing that goes back a long way ( I was taught physics by a guy who had worked on the Manchester 'baby' as a post grad) I can only say that the credit in using Linux for everything goes to the countless people who have worked on the kernel, written the GNU tools and assembled the distros.

Installing a modern distro ( I use OpenSuse ) is simple - FAR easier than Windows - but of course not many users do that do they ?.

If 90% of Windows users are incapable of using Linux I'd say they were also incapable of using Windows - I don't see the difference in easy of use. OpenSuse installs with no fuss, a good selection of user programs and no user involvement other than ticking boxes, accepting defaults and choosing language.

I simply can't believe that people who otherwise wouldn't dream of having their choice restricted to one car, one supermarket, one smartphone or whatever will blindly accept 1 OS.

Back in the eighties all sorts and manner of people got involved with a wide, wide range of micros, wrote software, built hardware, became professionals and yet now 90% of Windows users can't cope with anything else - rubbish - and IF that's true then it's the monopoly of MS that has brought it about.

Re: Linux was, is and remains a toy.

"Those who don't need or want much out of a computer will use it"

That's why I say nonsense - protein modeling requires large compute power and long run times. I'd run a twin xeon workstation flat out over the weekend and then put another run on for the next 3 days whilst still being able to analyse ( 3D graphics, liquid crystal shutter specs.) the previous run. The kit was running at ~100% cpu day after day. That's demanding - the software wasn't even written for Windows - not stable enough - no point running for two days if it crashes after 12 hours running.

At home I regularly run 2-3 hour sessions rendering video edits for 1080/50p HD video

Re: Re: "Windows is dead."

"I don't know a single person with a computer who does not also have a copy of Windows"

Allow me to introduce myself - I've been completely Windows free for 5 years - Linux only here, 4 desktops and server machines self-built, 1 laptop recycled to me after a Windows update failed disastrously , 1 net book always Linux .

I'm a retired scientist and even when I worked it was mostly on a twin Xeon Linux workstation using programs that were mostly VERY expensive and only available on Unix/Linux.

I don't need Windows - I can do everything I need on Linux. Apart from the scientific stuff that includes, browsing, e-mail, using Google Earth, processing RAW photo files, editing & viewing 1080/50p video, laying out pcbs, writing software and lots more. Libre Office is fine for my needs. A 3G dongle also works fine when traveling.

Intel joins The Document Foundation, pushes LibreOffice

Re: "people still pay $400 for productivity software."

Whether you really need or just think you need MS Office it can only be a good thing that there is choice. Choice in OS, software is good. NOBODY would put up with just one car manufacturer, supermarket, etc.

I used MS Office for years at work but find that LibreOffice is just fine for personal use. It may be a little slower or be missing some features at the moment but as I run 6 PCs I certainly find that zero cost is a big incentive. In any case I'm all Linux so Office isn't an option even if I felt the need.

I do know that LibreOffice copes far better with reading old or odd formats of data and that I will not have massive upgrade costs and upheaval when the next version comes out - unlike MS Office.

Crap PINs give wallet thieves 1-in-11 jackpot shot

Re: Re: Simple solution...

ISO9564

"The standard specifies that PINs shall be from four to twelve digits long, noting that longer PINs are more secure but harder to use. It also notes that not all systems support entry of PINs longer than six digits."

Certainly my Swiss UBS card is 6 digits ( and I think could be longer ).

I thought UK ATMs let you enter digits and then press <enter> rather than accepting a fixed number of presses.

And as I've mentioned before ..

.. the fact that people are willing to install a Linux on hardware that almost always they have to buy with Windows pre-installed and where most people don't care or know about Linux is a major triumph even if the desktop usage is ~1%.

I build all my own (except 1 laptop) so it's a no-brainer for me

There's an awful lot of people writing and compiling software for a desktop that you appear to think doesn't exist. Forget the enthusiast authors, major bits of software like Google Earth, Firefox, VLC, GIMP, Hugin, Thunderbird, LibreOffice, Opera are all available.

People tell me all the time that 'x' can't be done on Linux -they are almost always wrong. Only the other day someone said 3G dongles didn't work - they do., and someone else said that 1080/50p video couldn't be edited - It can.

Certainly package management has

..been rather rough in the past. I'm using 11.4 without any glitches on 6 machines. I see the latest version (12.1) has changed the management again so we'll have to see how it pans out.

It's still WAY better than total lack of management in Windows.
