"I expect somebody knows how to get Libre Office to print an address on an envelope and not across it."
Certainly I've never had any problems printing envelopes from Libre Office (although my Samsung laser, excellent in other ways, does tend to put a crease in the envelope)

"you don't have to buy it"
Are you suggesting that in a year or two you'll be able to buy a PC without it ?. I build my own and only use Linux but for most people ...
(Unless it all goes pear-shaped)
Re: The Year of Linux on the Desktop? Not yet.
Apart from any other considerations Linux on the desktop is only going to happen in appreciable numbers amongst non-technical or enthusiasts WHEN pre-loaded machines are readily available AND that's NOT going to happen due to pressure from Microsoft via discounts.
That said I use nothing else for all my computing ( 1 laptop, 1 netbook, 3 workstations and 1 server) and can do everything I want from editing 1080p/50 video, RAW photo manipulation, programming in a variety of languages, scientific modeling, pcb design and drafting and the usual browsing, writing and spreadsheets.
Re: Dr Magneto will see you now.
A similar kind of approach has been used with antibodies to tumours with attached 'lethal' payloads. It's more specific and can 'auto-locate' all the tumour cells - but it's very expensive to generate the pure antibody and attach the payload. This approach looks a lot cheaper ( I wish) and even if not as specific might be a lot better than conventional treatment with cytotoxic agents.
Re: A journey to Alpha Centauri
"What kinetic energy?"
The kinetic energy of the mass at 0.1C + the relativistic extra kinetic energy due to the increase of the mass at 0.1C.
It's an absolutely enormous amount of energy - it's about 1E18 J to get a tonne to 0.1C
Re: Fermi, Tesla, and Maxwell would all want one
"Physicists (and not just physicists) always want more compute power than currently available."
Strongly agree !
Re: I remember a review ..
Could be - it was a LONG time ago - a different world
I remember a review ..
in Practical Electronics or Wireless World where they jokes that there were a range of peripherals coming along like parallel ports, serial ports, memory expansion and space shuttles - I think MOS had some connection with Rockwell who were the main contractor for the shuttle.
Re: More information:
"In terms of energy per kilogram, hydrogen is almost an order of magnitude"
Not as far as I know.
Hydrogen ~ 140 MJ/kg
Diesel ~ 45 MJ/kg
Re: Backward step
Ethanol indeed but technically that's not a hydrocarbon. Hydrocarbons only have carbon and hydrogen but indeed that's semantics to a general audience
Re: Backward step
"to productionise hydrogen in safer ways and wean us off our carbo"
Producing it safely is not the problem - getting the energy to produce it is.
Whatever way you make it needs energy - 2H2+O2 -> water +~~600kJ/mol So you need at least that and indeed a lot more to produce hydrogen gas. So >1MJ to produce about 70 litres of hydrogen gas.
Distribution and storage are also problems
Re: Backward step
"Beer ... because it contains a hydrocarbon"
Well it might have a trace but I think you mean carbohydrate
Re: More information please
Roughly 3 times as much energy by mass for hydrogen compared to kerosene. But liquid density roughly an order of magnitude less. So I'd assume the tank needs to be 3 times the size for the same energy content AND capable of holding cryogenic fuel.
and I thought my Avon inflatable sportsboat was tough.
his engineers have found batteries that could power a flight for 100km (62 miles).
Does anyone believe that ?
For a helicopter !
I think you'll find that..
it was hit by a meteoroid in just the part of its structure where the impact detection equipment was located ( or something similar)
Re: Another Big Patch Day, and a Week of Start Up Repair Routines
I think you'll find that the EeePC runs OpenSuse very well and Firefox and Thunderbird will give all the functionality you currently need.
I've installed Linux on laptops
~6 averaging about 3-4 versions each machine over the years and wifi has been the only problem and that only on some and that seems to have gone away in the last few years.
Mostly OpenSuse and Kubuntu
Re: Unix workstations
Lots of areas of science and technology use Unix/Linux and can't move anyway ( even if they wanted to ) as the software they use has never been ported to Windows. I went on secondment in ~2004 to a department that used SGIs and had done for years and they had started moving to Linux in ~2000 as the cost saving/performance SGI > PC was considerable - the saving in moving to Linux was less relevant as much of the specialist software used was VERY expensive.

Re: What monopoly MS + entertainment industry = less on your computer...
"TIRED OF FEATURES DISAPPEARING FROM THE MS OS with every new version. REPLACE STEVE BALLMER NOW!"
I never realised he had been a feature of the OS and (even if I used WINDOWS) I wouldn't want him back !
"and that they break as soon as a X or Kernel upgrade comes out"
NEVER had that happen
I'd suggest you use a Live-CD ( or USB if you can boot from one) of a modern distro like OpenSuse 11.4 or 12.1 ) and see before you install if the wireless problem is still there. If it is then your wireless system might be rather a rare one. Most wireless chipsets are now supported, some of them officially by the manufacturers.
"the company does not provide them"
The company DO provide them but only as binaries. Hence the project to emulate them
Re: Hell's freezing over!
I don't have an optical drive on my Linux netbook but I do load images of DVDs from my network to watch when travelling.
"Most people don't want to have to get on a forum in order for their PC to play a DVD."
Most people don't have to !
Re : mplayer
mplayer certainly seems to use less CPU on any of my Linux boxes regardless of whether the video is accelerated or not.
Doesn't fit with your experience of hot or not but it's what I've noticed
I know you are joking but some people may not know that the VDPAU drivers for X give excellent GPU acceleration on modern-ish Nvidia cards
Something very wrong then.
I use DVDs on all my various Linux boxes without any problems also I can play HD720p on an old Celeron laptop and edit/play mp4 1080/50p videos on an old 2 core AMD using Nvidia/ VDPAU using ~5% CPU.
Sorry I can't really attempt to diagnose what's wrong but definitely something is.
"It's not the miscopying, it's the duplication"
That is very common in the genome
"Cos no one want or needs a 3rd eco system"
No ? But we've been assured by those nice Redmond people that Windows Phone will mean genuine, honest-to-goodness competition - which is GOOD for the market - only a FOOL would want a complex technological market to be a monopoly.
I'll just get back to my desktop now ......
"what do you do with all the salt?"
It's brine that's higher in salt than the source. Just dump it in the sea - most of the pure water generated is going to end up there fairly quickly so the sea isn't going to get any saltier

Having butchered a Dragon to give it a PIA ( peripheral interface adaptor ) so that I could run my home-made EPROM programmer I then needed a 6800 assembler for a 6802 based burglar alarm I was building so I wrote one in BASIC - it took about 2 HOURS to assemble ~ 200 lines of 6800 assembler.
Never used BASIC again !
Re: Shop demo models
I remember getting an Apple II for the lab and programming a little BASIC that put up a normal Apple prompt ( ] I think ) any keypress then produced a "SOD OFF" for a few seconds before the program then deleted itself and returned to the normal prompt.
Yes indeed, bought it, built it - it didn't work, debugged it with a xtal earpiece , found a 7400 not working and bob's your uncle.
MOST noticeable for a garbage-collection bug in the MS BASIC.
Having spent the last few years doing just this sort of thing I must explain that it's REALLY hard. Not to get software to filter out the 'best binding' ligands but to find that reality rather foolishly doesn't agree with the output.
Re: You want hardcore?

"I prefer the idea that most of the dinosaurs left before the extinction event."
You may prefer it but it is now known that it was the DOLPHINS that left (playfully) before the extinction event
Re: Migrate before ...
"can you shove in a disc and let it do the set-up work for you? No."
That's what I've done for years with Suse & OpenSuse. since ~2000 - must run to a good few dozen installs by now as I currently have 6 machines
"Linux viruses in the wild"
I didn't actually say that - the known viruses are more curiosities, they never spread far as the architecture is rather unfriendly. Most of the antiviruses look for Windows viruses to stop them being passed on.
"dodgy stuff" account, you're still infected."
"dodgy account " is still infected true but it's all just still extra layers of defence. Other accounts will not be so 'safe' account is still less vulnerable. Of course if a further vuln. allow escalation then that is a different matter.
"dodgy account" by the way is deleted/recreated at weekly intervals
Too complex a topic to describe in detail here but LONG complex passwords, multiple accounts, firewalls, NAT routers, Firefox/Noscript/ABP and a lot of other techniques alongside using Linux have kept me safe over the years.
Keeping an eye on the logs is useful. I esp. look for SSH attempts which is my only open port ( protected by unusual port number, one unusual account name and a long, difficult password)
It's well known that Unix/Linux systems can get viruses - the difference has been that they've never become a widespread problem.
In any case if you want to be more sure in a Unix type OS use different accounts for different things.
I have an account I ONLY use for really important stuff like banking and another for for visiting sites that MIGHT be dubious. It's so easy to switch why not. Unless you can't be ars*d in which case you deserve all you get.

OPERA is an experiment at Gran Sasso and really all CERN did was provide the neutrinos
Sounds more like ...
there has been a lot of strain in the OPERA collaboration - it's a big experiment (1300 tonnes) and a large, varied team. Measuring neutrino velocity wasn't the major reason for OPERA in any case - it was intended to look at neutrino oscillations from one type to another.
