Just upgraded my laptop from F14 - F15 with preupgrade. It all went very well.
Congrats everyone!
I've been playing around with gnome-3 for about an hour and I'm getting the hang of it. It's definitely different and is certainly cool. I miss is my cute little applets especially power, network and system load. Are they gone from gnome-3?
Also I'd like to change the pure white text on black theme of the bar thingy at the top of the screen.
A politician swims in the superficial memes of popular sentiment. He maybe an ideologue but a successful one is also a pragmatist: he shapes truth into what is most convenient for the occasion and in doing so may actually benefit from self-delusion, even intentional and conscious.
You are exactly right. The most effective leaders appear entirely sure of the outcome of their own decisions. A large amount of self-delusion is very helpful in this regard.
This thing cost 25 million to make and apparently stores 192000 KWHr of energy. That is $130/KWHr. On average my home uses 17 KWHr/day so I can store my average needs for only $2210.00.
Thats a small additional cost on the 6 KW of Peak Power worth of PV's I need to provide the 17 KWHr for my house.
You miss the point of the Fermi Paradox entirely. Given that humans have only been in existence on earth for 200K Years, why is it that no aliens have colonised Earth *before* we got here? It would take only one expansionist alien culture to exist in the billions of years the galaxy has existed before us and the Earth and the entire galaxy would have been well and truely colonized already.
I mean some relatively straight-forward extrapolations of humans shows *us* colonizing the galaxy in a few million years.
Basically the Fermi paradox says, they are *no* other intelligent civilizations in the galaxy otherwise we would have had dramatic evidence on Earth.
Still I see no particular harm in continuing to look. If something were found it would be a monumental breakthrough.
Clicking "open" on the doc automatically loads the doc into abiword, which you can annotate as you like. Clicking "save" in abiword sends it back to http://abocollab.net./
You can easily share and collaborate in real-time. You can tag your docs, share then amongst groups of people etc.
I guess it's not quite what you're after but it's collaboration features might make it work better than you expect.
I read that blog post. Very, very funny. Telstra in Australia provide exactly the same useless crap for 3 times as much money as SPRINT did back in 2006. Some things never change.
What is relevant here are words! There is a huge market for "romantic" novels pitched at women with very detailed sex scenes. I agree with GP it's just as likely that an embarrassing email may emerge from women:-)
There are very few Open Source developers for OSX. Unfortunately we, AbiWord, have exactly the same issue. We *almost* had version 2.8 ready for OSX but we lost our lead OSX developer and there is no one to replace him. Rather than delay 2.8, we simply went ahead with 2.8 for Linux and Windows.
We hear you. This can easily be arranged. The service can be deployed on a smallish server that could easily handle several hundred simultaneous collaborative documents (enough for a high school for example) or scale up to handle what we expect from the whole web. Most of the processing grunt needed is actually in the clients. This a huge advantage compared to Google apps which rely on the server for their CPU cycles.
Eventually, I'd like to see the collab move toward Telepathy so that I can just use my contact list and connect that way.
Yes. We're quite a way along the path to getting a fully fledged telepathy backend working. Like all these things in Free Software, we could do with more resources. We finally got the web interface all sorted out though, so now it's released.
You are right in that the website has lots of additional and useful features. Like having the full history of the document and extremely easy web publication of the document in pdf, html, odt rtf, docx etc.
In answer to your questions: 1. Because it allows collaborative editing for documents hosted on a website. Press "save" in abiword of a document loaded from the site and it is saved back to the site. Just like google docs and zoho.
2. Because some people do need to work together to create documents. Ever had a document emailed to you that requested changes? Now you just connect straight on the service.
3. Your assumption is incorrect. Sharepoint does not allow the deep, instant collaboration between arbitrarily sized collection of people provided by abiword+abiword. Certainly not at the price offered by abicollab.net ether ($0.00).
One of the most touted features of OLPC is the "Write" word processor which allows children to work on documents together. Now everyone with a Windows or Linux computer can do that in a fully fledged word processor.
Sorry, I didn't mean the net effect of climate change, I meant the net amount of ice in Greenland and Antarctica. From the data provided it's not obvious that Greenland and Antarctica are losing ice. For example there are very large blue/green regions (gaining ice) that by eye could be bigger than the red regions (losing ice).
The other question is regards climate model predictions. One of the catastrophic outcomes of climate change are large sea level rises due to ice melt in the polar regions. Presumably there are models that predict how this could occur with global warming. So the question is, do these data agree with these models?
I'm no climate change skeptic, but from just looking at the images it's not clear that the reduction in some places is not balanced by the increase in others. What is the net effect? Can these data be compared to model predictions?
The problem with Solar thermal is that it is the energy source in inherently diffuse and to get high efficiencies you need high temperatures.
It will be very hard to make up the factor 5 difference in cost for solar thermal vs coal. They have a better bet at developing a cheaper form of nuclear power where the energy density is 1 million times higher than coal.
Of course cheaper nuclear has a different set of problems but at least you start out on the right side of the energy density equation.
I'm a Physicist but essentially I have to demure to the Climate Modelling experts too.
At first glance it appears that the extra CO2 in the atmosphere will make very little difference to the global temperature.
Why? Well the best models predict an effective increase of 1-2 watts per/m^2 of energy directed back to Eath from the addition CO2.
On the other hand the amount of power radiated into space from the Earth is to first approximation, given by the Steffan-Boltzmann equation.
Power = sigma*T^4
Where T is the Earth's temperature in Kelvin ~ 283 C.
The T^4 means you get a lot of extra radiated power for a very little increase in temperature. Roughly a 0.3 degree increase in temperature for a doubling of the CO2 levels.
To get the 3 - 7 degree increases predicted, you need a really big positive feedback effect from additional water vapour. But additional water vapour also provides clouds which either increase the amount of power reflected back into space or increase the greenhouse effect, depending on where they form.
It's a really complicated problem.
So one can only hope that the authorities have got it right.
So your counter argument that an observed weather phenomenon on the opposite side of the planet casts into doubt the mountain of data that the north pole is losing its sea ice (to the detriment of Polar Bears) is scientific?
Talk about appealing to false causality. Was Katrina caused by GW? Who knows. One point of data trend does not make. Is the Arctic Melting caused by the fact that it's getting warmer, along with the rest of the planet on average? That's a pretty hard thing to disprove with millions of points of data all pointing to the same thing "The earth is warming."
The trouble that CS students find themselves is that there is a very, very large differential between the best and the average of their profession.
If you personally want to find out where you're at, join an Open Source project and see where you find yourself.
If you don't want to join an Open Source project because it's not fun for you anyway, then you're in the "average" category and adjust your career expectations accordingly.
Slashdot Mirror
A quick scan of the arXiv shows a fair bit of research on this topic. I'm by no means an expert but a lot looks like serious work.
http://arxiv.org/find/all/1/all:+AND+will+AND+quantum+free/0/1/0/all/0/1
This one looks particularly interesting.

There appears to be a lot more to this than "QM is mysterious" "Consciousness is mysterious" therefore QM is related to consciousness.

The existence of this project makes my want to buy an android phone.
No lockin for me!
Hey, if Apple want a walled garden you don't want to play, don't. They're not the only game in town.

Does this thing scale down?

Actually Lithium-air batteries have a theoretical energy density of ~40 MJ/Kg which is about the same as Gasoline.

Of course these are a long way from commercial deployment.

It is still an interesting idea. A purpose built trailer with a 12 KW engine + fuel tank => unlimited travel.

My heart rate regularly gets up over 120 beats/min after I made it to "medium" level. Thats better than a brisk walk for exercise!
