I did modify my numbers in the later post - the initial post was off the top of my head. I went back and checked the data and I was wrong first time around. It really doesn't change my point though.
You are correct - CO2 does generally lag warming in historical terms (But you are missing the point - we already know how much the greenhouse effect warms the planet (about 33 degrees). The contribution of CO2 to that warming is fairly established (between 8 and 9 degrees)... for the record the greenhouse effect is a good thing, too much is bad. We also have a good idea of how much extra heat energy should be trapped by the increase in CO2 and this lines up with the collected data.
So the fact that CO2 lags behind climate change tells us that CO2 is not what *usually* causes climate change. It does show that as the climate changes trapped CO2 (and more CH4) is released into the atmosphere. This would indicate a positive feedback system comes into play at a certain point. We know at some point other factors kick in and temperatures dive again however I don't know if most of us especially those in the lower areas of the world really want to reach particularly if it is the end result of our own greed. It's the positive feedback system that scientists are generally worried about.
I gather that you are asserting that the increase in CO2 could be from natural causes the two things you mentioned would be things that happen as a result of warming - part of the feedback system that happens as a result of temperature change and although they contribute to the situation they would not be the route cause. Now you could claim that the initial cause to be global cosmic radiation or some such - but then you would have to explain why there has been no overall trend in global cosmic radiation in the 60 years we have been measuring it. You might also want to explain why we see a marked increase in CO2 in the atmosphere coinciding with the beginning of the industrial revolution.
The earth hasn't cooled over the last decade it has stayed fairly level in temperature. The oceans however have risen in temperature. The distribution however is not even however a disproportionate amount of warming is happening in the artic area. I hear assertions like this being made all the time but when you look closely at the debate from both sides it just doesn't hold water. where exactly did these mathematicians show the "hockey graph" to be bogus?
Yes and no.... Quite frankly if you want to deny carbon dioxide is what we should focus on then you should perhaps take it to the scientific community and come up with a model for climate that doesn't take human CO2 emissions into account and can explain temperature patterns since ~1975.
Since about 1970 the amount of atmospheric carbon dioxide in the atmosphere was about 300ppm its now up around 370-380 ppm. In that time there hasn't been a significant increase in natural production of CO2 and an overall increase of CO2 by about 33%. That is a no minuscule amount. While your assertion that the natural world produces a lot more carbon dioxide than humans do is correct you are not taking into account that the natural world in general also sinks that carbon dioxide. The amount that humans produce doesn't need to be that big it just has to be big enough to unbalance the system.
I don't think they are at any great risk in the high end content creation market into the medium term... But I guess the real question is what happens in the general consumer market.
Depends on your circumstances.... nVidia's still has much better overall stability and drivers (this matters if you are developing content). nVidia has much better OpenGL support - nVidia supports pretty much everything available to their DirectX drivers through OpenGL - with AMD this is not the case. If you happen to be on Linux or you are doing cross platform then Nvidia is still the better choice.
The latest AMD cards do perform very nicely though in terms of hardware. Also it depends on what your definition of High End is... I am not aware of what AMD has on the market to compete with the QUATRO or higher end GPUs.
MS currently has the NSW school system eating out of its hands I remember talking to a highschool teacher a few years back who was sharing his concerns that MS had basically brokered a deal with them where they could not teach competing products. I have not seen the actual agreement so I don't have anything solid to back it up with.
Reading between the lines when talking with the IT head of TAFE in my region of NSW basically told the same story. (We were trying to reach an arangement for Tafe to use some facilities we had for outreach courses).
The problem in this case is that Flash is something of a Dog on Linux.... also In many cases video drivers are not as well optimised either.
Over the years I have found that Windows feels snappier on an unloaded system whereas Linux generally tends to feel better on a machine under heavy load.
Actually you can Run KDE on top of jack - since Xine (and therefore phonon) now has a jack backend.

KDE 4.3 Released
·
· Score: 2, Informative
KWin seems to run fine with compositing switched on and opengl games.... I know that because I work on a game engine all day (it's my day job) and I am running KDE 4.3 desktop. Furthermore compositing can be switched on and off with using SHIFT + ALT + F12 (compositing does cause a modest loss in FPS). Furthermore compositing is automatically disabled in any fullscreen app.
Also note that I am running a reasonably recent and highend nVidia card on this machine.
It mostly has -- For better or for worse Kubuntu already has that version. It still isn't as stable as I would like... for more info on why it took such a long time you can look at http://www.k3b.org
This seemed to be time based... if it hasn't done filtering the list you may need to press enter a second time. Though really I only have two words of advice....
It seems to work fine as a launcher here - it seems to need a fraction of a second to filter the list before it can launch stuff though... If you really want to operate that way though - using ALT + F2 to activate krunner is a much more sensible way of doing things...
The Realtime kernel tends to be less stable than the stock kernel. I have had some pieces of hardware where the realtime kernel refuses to boot at all.
The realtime kernels in 8.10 and 9.04 really weren't worth the effort. 9.04 has a really good stock kernel for audio work. 9.10 (to be released in October) already has a really good realtime kernel (I am using it as we speak) which is handy because the stock kernel is terrible.
There are options for 16+ channels Audio hardware. MOTU is not on the list as explained in the below post.

In addition Saffire is very active in its support for linux with its firewire soundcard range and presonus hardware tends to work (this is what I use). The newer dice based hardware works will be officially supported after the release of ffado 1.0... as explained in the following
And all the open source vendors need to do to support MP4 and H264 out of the box is pay 5 million per year (the maximum cap - since there are no way of tracking the actual number of users). I am sure that a not for profit orginisation like Mozilla has that kind of cash lying around in their back pockets. I am pretty sure that this would be concidered an undue financial burden for Opera as well.
If it were not for this issue I mp3 and mpeg4 would be a happily agreed standard. (well except for microsoft - but its not like they are ever going to come to the party)...
What needs to happen is there needs to be a licensing provision that is usable by not for profit open source vendors. That could be a provision where an end user can pay a few dollars to be able to use the codecs with what ever software they see fit (hey it's money that they wouldn't otherwise be getting otherwise). Or it could be a smaller more affordable cap for a not for profit entity.
Your assertion that open source projects almost never support drag and drop doesn't bear out for me in practice... I use a foss Desktop pretty heavily (kde) and I regularly use drag and drop in my workflow. Here are some of the projects I regularly drag and drop between: Dolphin (file manger), Digikam (photo organizer), Gimp (Raster Graphics), Inkscape (Illustration), Scribus (dtp), Amarok (music Playback), Kate(text editor). Ok my 3D programs don't (Blender,Wings3d)... But the vast majority of the foss programs I use do support drag and drop.
Linux generally has for years.... XWindows (the graphic layer) didn't until relatively recently. (that covers things like mice, tablets & keyboards) last time I looked tablet hotplugging was less than perfect but plugging keyboards and mice work seemlessly for me.
Storage Devices and Cameras have been hotplugable for years UsbMidi Interfaces and Soundcards are hotpluggable and have been for some time. Joysticks are hotpluggable. Printers and Scanners to the best of my recollection will also hotplug.
I am curious to know what is wrong with the search function in Kate.... I use kate on a daily basis and I like the way the search tool in 4 is implemented.
well yeah Amarok is a complete rewrite... and yes music brainz functionality or equivalent has not been added in again. At the moment I am using Picard for this (the official musicbrainz app)... Amarok-2.0 or even 2.1 is not yet a fully functional replacement for 1.4...
Smart Playlists.... Actually there but the UI has been much simplified and seems to be able to do everything I remember doing with 1.4 and a few things I couldn't. I actually thing this is one area where amarok has improved.
Wikipedia plugin -- Is definitely there - it is uglier than the older version but still definitely there. You access it in a different way.
Ipod support - believe is back in but not as functional as in 1.4 (I could be wrong on this one)
Postgresql - basically the devs got sick of maintaining 3 seperate database backends and decided to standardise on one.
Your problems are probably further down the stack. KDE for better or worse uses parts of other underlying graphics stack that other desktop environments don't yet. With hardware that implements these features well KDE is very smooth. For a lot of people It is not - this is because the parts of the driver architecture that KDE uses haven't previously been real world tested. As X and the graphics drivers for your machine improve you will probably see a speed improvement.
As to your comments about beautiful by default. I agree that the defaults in KDE could be better. - but - beauty is largely a subjective thing and what I might find beautiful and you may find ugly. AS to why space being wasted - The perception of this can vary hugely depending on the size of display you are using and the pixel density. The challenge I guess is to get something that scales well.
Ummmm no..... We are pretty much all Vista at work but nobody likes it.... Probably the most loved vista feature is the fact that it will just decided that you are not allowed to modify a file or folder on a whim....
Not if you buy the components and put it together yourself... Not that everybody wants to do that but it isn't exactly a difficult task once you know what each bit is and what it does... even easier if you buy a barebones machine.

Sorry I did get my figures wrong
the figures are 280 ppm - 380pmm in the last 150 years
so about 35% for the last 150 years...
the 300ppm figure I was out on - The figure I can find is 323ppm
which is an increase of
~17% in the last 40 years.
