"I can't use the software provided with my Canon DSLR without Windows"

I only use Linux and have 2 Canon DSLRs - I don't find it necessary to use the Canon software.

I can process the raw files to 48bit tifs, adjust exposures etc and drive the camera remotely all from Linux.

Re: "Comfortable with the terminal"

@Michael Habel

NVIDIA drivers install perfectly in my experience (OpenSUSE) and that's on about 10-15 occasions in recent years.

I've never seen "You appear to be running an X server please exit X before installing"

I just install from the NVIDIA repository and logout and back in. NO CLI

Re: Mint is great but ...

"Security seems to be such an afterthought in Linux with add-ons like SEL and having to run specific file systems to get proper ACLs, instead of having security built in from the ground up like in Windows."

Well you stick with Windows if you are so confident - I know what OS is feel most confident with.

I did qualify it by saying it enhanced the experience, I also used the words "most modern "

You might well have had a problem with one install of one distro where you needed the command line but most people don't have with most modern distros

Re: "Comfortable with the terminal"

"Until you want to use something that isn't in the official package manager,"

I do often without using the command-line - the point is that an install and use of the (GUI) installed packages doesn't need the command-line. I'm not against the CLI - indeed I use it all the time as I write a lot of programs as well as building/running scripts but there are far too many people out there who spread the FUD " Linux installations need CLI or programs compiling or whatever else. "

They don't !

Re: Test 'em first in VMs if you can.

"Nothing worse than downloading an ISO, burning it to disc or USB and then watching it crap out half-way through a real hardware install"

Don't do it then. Use a LiveCD that will not affect your existing setup. Check if the hardware works that way then install.

There are several liveCDs at : http://software.opensuse.org/122/en

For the last griefing time - You do NOT need to use a command line to install or use most modern Linux distros.

BUT if you do it can greatly enhance the experience.

Whilst it might be useful to try a few distros I find that long-term sticking with one distro/desktop means a much easier life. Of course I occasionally still try new or 'improved' distros but generally in a VM.

For me OpenSUSE/KDE has proved super stable, easy to install on all sorts of hardware including by USB pendrive and has a wide range of programs including many not actually in the distribution.

"Although I think a lot of their experiments are far fetched this is actually an area which the Mythbusters covered quite excellently (in my humble opinion that is)."

I think JassMan has already pointed out above that a number of solar furnaces/power stations using mirror arrays are already established. So Mythbusters or legend means nothing.

Re: Somebody takes it...

" Somebody takes it...

and hopefully makes some kind of liquid fuel from it"

As mentioned previously.

Carbon burning to CO2 gives off ~400 kJ/mol or ~ 34MJ/kg - there's no other oxidation state to go to - any other chemical change NEEDS energy so it's hardly likely to be a useful power source. Maybe you'd take a hit, use energy to make a new liquid fuel, but it's now just an energy carrier like batteries or hydrogen.

And then it still ends up back in the atmosphere !

"and converting the C into something solid like"

and converting the C into something solid like CARBON

In any case the problem is, even in theory, it needs energy, lots and lots of it, indeed somewhat more energy than was obtained by burning the carbon in the first place.

Re: Ironically...

I think you are confusing a specific chemical with the azobenzene class. As far as I can see a particular azobenzene is bonded to this large-surface area material.

The analogy would be sodium cyanide is very toxic but the cyanide group (a nitrile actually) can be part of an organic molecule without any sig. toxic effects. In fact the breast-cancer treatment Arimidex contains 2 nitriles.

Re: how come no one ever mentions the $ to charge these cars

As 85kWh has been used as an example just calculate using whatever your local electricity cost is - here it would be ~£10 excluding any losses. I could travel ~ 90 miles in my diesel for that - mind that weighs 1.7 tonnes and carries 5+2

On the other hand if electric vehicles did take a good portion of the market they'd be taxed in some way

Re: Electric vehicles are a joke until storage density and infrastructure get MUCH denser.

" Gas is easy to transport or make on site (for H)"

This hydrogen, if you make it on site presumably by electrolysis the efficiency is poor. Electrolysis generates a lot of waste heat. If the electricity is generated by coal/gas/oil the overall efficiency is likely to be < 20%.

How are you going to store it in the vehicle ? Either compression or cryogenics requires a large amount of energy and each has it's own problems anyway. The overall efficiency is now ~~ 5%

Re: Gimp has CMYK.

"Gimp has CMYK now"

It certainly has had the ability to generate a range of color separations ( including CMPK) for a while, whether this is sufficient for the OP I don't know as my knowledge in this area is limited.

For info the menu option is Colours - Components - Decompose - Choose 1 of~12 options (GIMP 2.6.11).

I don't actually use GIMP a lot as my main interest is processing RAW digital photo files and there are much better programs in Linux to process in 48-bit etc

Re: this is not by choice

Searching on-line for usage figures for LO & OO gives widely varying and likely highly inaccurate figures. This to be expected of course. However the more telling statistics are how many articles try to downplay the usage.

One can ask to what purpose. If the usage is minimal it scarcely warrants mention surely. Have all these people nothing better to do than be critical of something they seem to think has very limited distribution ?

"This project got in jeopardy around 2003"

AFAIK the project only started in 2003 and it wasn't until 2006 that implementation started. By 2013 there were ~13000 workstations running a specific Linux variant based on Ubuntu but with a KDE desktop.

I also find it rather telling that MS claims that the move to Linux cost more than staying with MS but has declined to publish the study they did on this.

Re: Einhorn's Ulterior Motif

"He is bound to find a bunch of share holders which believe his version of reality and vote his way."

That's the way companies work. If other shareholders are stupid enough to not check what he's saying then they deserve all they get. Generally large shareholders are NOT stupid and can employ people to check.

I wasn't thinking specifically of this case when I discussed returning shareholder value but in general it's true with the caveat that the shareholders would have to vote for the dissolution/merger/takeover of the company.

I've no idea of the motives of Einhorn, I'm just taking exception to the idea that shareholders have to accept what THEIR board of directors says. It isn't so. Remember the directors work for the shareholders. If I own part of a company and the directors either make a mess or merely collect a cash pile that they might be using to grow the business it's MY investment that is affected ( and of course the workers)

Re: Einhorn's Ulterior Motif

""When you buy stock in a company, you must agree with the way the company is managed""

When you own stock you own a share of the company. If you have enough stock or supporters then you are fully entitled to change the way the company is managed. That's why shareholders can vote.

Indeed if a company can't see any future in what it does it's the duty of the directors to return as much value to the shareholders as they can. One of the reasons for taking a company private is to avoid shareholder involvement, although like Dell you might end-up in regretting that.
