Re : point

Should have been "Global warming isn't driven DIRECTLY by man-made energy generation." Of course any generation that involves carbon dioxide production may well drive global warming

Re : point

Why is more generation bad ?

Global warming isn't driven by man-made energy generation. All the man-made generation is SWAMPED by solar radiation - it's about 70000 times the electricity generation on the planet. Total solar radiation striking the earth is about 5E24J /year which dwarfs man-made generation. The total output of the sun is 10 orders of magnitude greater than the radiation arriving on earth and that's a little star in a quiet backwater. So I don't think humans are contributing to the eventual heat death of the universe in a meaningful way.

LHC boffins crank beams to 3.5 TeV redline

Keith Oldham

Re : that was meant as a compliment

At ~4 moles/kg the energy from 77kg TNT will be ~350 MJ which fits with the kinetic energy for the carrier and the LHC beam energy at 7TeV

Re : 7 TeV not going to budge a navy carrier

Indeed one proton with an energy of 7TeV would not move much

362 MJ is the BEAM energy ( according to CERN) at 7TeV which fits with the energy of the ship

But the beam has 2088 bunches of protons, each bunch consisting of 1.15E11 protons - each PROTON has 7TeV

Re : Bollox

Never heard such rubbish - and that's saying something on The Register.

Firefox works fine even with Flash

VLC and other videoviewers - fine

mp3 - fine

Stability - rock solid (my fileserver - 3 months and that's only because of a kernel update)

Re : Makes me feel old too!

When we got our first Apple II in the lab I wrote a little program that showed the usual prompt ( ] I think), anyone that then typed in anything got the message "B*gger Off !" which remained for ~5 seconds, the program was then deleted and the normal prompt returned.

Re : Really?

So ?

For the vast majority the slightly-reduced functionality will be more than offset by the zero cost. Given that OpenOffice will read more formats than Office, write PDFs it suits many people who don't need to be forced to use Office by corporate dictat.

I've built a fileserver for (much) less than the cost of Office.

If you want to use it then pay up just don't ruin it for others who can try OpenOffice without laying out any cash and may never need to.

I speak as someone who used Excel every day for years in a corporate scientific environment, often dealing with data set sizes that Excel couldn't handle.

Re : err

OpenOffice WILL fulfill many peoples requirements - if you think it unsuitable for you then pay up. Excel may suit most people especially if they never try OpenOffice.

Re : Soooo

I think a hash derived from a 256 bit salt and a 'random' 20 digit password with upper/lowercase, numbers and symbols might take quite a time to crack.

Re : Soooo

SSD tools crack passwords 100 times faster

Keith Oldham
Silver badge
Linux

Re : Presumably

I'm not by any stretch any kind of expert about this and I guess you should do some research but for what it's worth ..

Most Unix-like OS now use a randomly-generated 'salt' string (each time password is created/changed ) and use it as part of the hashing function, storing the salt, along with the hash as the users 'credentials'. This essentially forces the cracker to generate another rainbow table set for every permutation generated by the salt - so for a 256-bit salt - that means 2^256 rainbow tables of 80GB or whatever need to be pre-computed OR a specific table needs to be generated for every individual password

Not sure about Windows - I don't have anything to do with it anymore. But I don't think salting was used pre-Vista

Hope this helps

Re : Huh?

Oddly enough I have read the article and the related links and Leo is correct. This is about a Windows trojan variant - nothing to do with Mac OSX or Linux or Unix or BSDs. Nothing to do with pirating anything other than the (protected) trojan.

Leo did say "(maybe not for ever, but for now)"

Re : Open Office

Can you justify this statement ?

Just because something resembles another & performs similar functions isn't grounds for patents. ( At least not in sensible parts of the world). Indeed many complaints about OpenOffice is that it doesn't behave/look exactly like Office.

I and every other pharma. chemist have patented drugs that treat diseases in EXACTLY the same way as other companies compounds - perfectly legit. The market decides which to use depending on other factors such as efficacy, price, dose, side-effects etc.

Have you compared the source-codes ? -thought not

Lots of complaints about spam killing e-mail in the comments above. I think it depends on your ISP (Plusnet in our case ) These days our ISP's system does a great job removing essentially all spam.

For the record we've used Thunderbird for years + web-based access when traveling - and yes we've had our own domain name for years.

Re : could not, in all conscience suggest a Linux build for a stable desktop, given my experience..

Must be a VERY limited experience.

I've used SuSE & OpenSUSE for ~10 years without any problem with the (usually KDE) desktop.

Does everything I want either better than Windows, as well as Windows or at least adequately.

That would include :-

File& print serving to Windows & Linux boxes

Firefox

e-mail

Google Earth

Web-page generation

C & C++ compiling + almost any programming language you could require.

OpenOffice

Video editing

RAW digital photo processing

Panoramic photo processing

TV viewing /recording

SSH access to home server

Remote access to my wife's school

Microcontroller programming (PIC) via WINE

If you need games or really feel that you must have Windows fair enough. But the ignorant or malicious comments of others that Linux NEEDS a CLI for installation or routine use or even that you NEED to compile programs to use it needs refuting at every opportunity.

Just get a LiveCD and try it !

Some might be impressed by your stupid ( and offensive ) reasons but they seem unlikely to have affected the choice of GNU/Linux for the bulk of supercomputer systems, the bulk of internet servers, all those the embedded systems and the more intelligent desktop user.

I'm just a little puzzled that you seem so threatened by an OS that you both despise and yet clearly don't understand.

The Higgs Boson is not the boson of gravity - the Higgs field ( and so by quantum mechanics has an equ. particle) is supposed to give particles mass

Re : What the fuck?

It does explain in the linked article that 11000 are added, 5500 removed and 2200 altered and that core kernel code is only ~5%. Most of the new code is for drivers/processors.

It goes quite a long way to explain how each new release works on more and more hardware to the point where installing a modern distribution is now trivial on desktops, at least

Re : One more reason FTL travel is not currently possible possible.

"Even though there is a point at which acceleration causes the human body to cease working, that point occurs when you are travelling a lot faster than 20 mph."

This so much fun but what has speed/velocity to do with acceleration. ?

Acceleration between 0 and 5 mph would kill you if it were sufficiently rapid. Don't take my word for it just drop a fine wine glass onto concrete from ~20 cm

Re : MS Office >> openoffice

Bol??cks !

I've used huge, complex Excel spreadsheets in a scientific environment - many so large, that Excel couldn't cope and I had to shift to JMP. Of course OO isn't as fast or quite as capable BUT for most users it's good enough given that it's FREE and runs on Linux as well. If you really need it ( or think you do) spend the money - but don't patronize - OO will run really complex sheets within its limits which are considerable. You will not build a cogent argument by exaggerating !

Is it a laptop thing ?

It would be interesting to know, Although installation of a modern Linux distribution is easy on most desktops it can be somewhat more difficult on laptops unless a little research is done first - esp. choosing laptops with wireless chipsets that work "out of the box".

Or is it that the developers are constrained by corporate Office/Exchange etc. ?
