A lot of comments on this in the thread. Energy is conserved but the question is where does the energy go when you walk on a normal surface. If you have a solid immovable floor the energy you impart onto the surface through friction gets dissipated as heat (slight bending of the material, compacting of the earth...). If you could "dissipate" this energy into electricity it might not be significantly harder to walk on such a surface. Also, if these are just piezos than you are basically just bouncing on what feels like slightly softer surface and I don't see that as a big problem. The practical issues however are a different story (maintenance, efficiency, cost/benefit).
I just installed the latest update for windows 2000 on my wife's computer and it hosed the installation. I assume it included these latest patches. Has anybody had a similar experience? I am getting a "SYSTEMced corrupt or missing" error which google tells me has to do with registry problems.
Your post refers to a different researcher with a different theory. The main post talks about a different group with a theory that might seem more convincing.
I completely agree. I think they might have had some problems with "creativity" and "innovation" if the one of the best examples of their work he could come up with in that writeup is the spinning clock. You can buy gadgets similar to these in every cheap souvenir store so I don't see how someone would have the guts to display this as an example of creative achievement pushing the envelope. Or phones that require a pool to be operated...
Correction. Everything I said has to do with Cassini and you were asking about the probe. The websites though have info on both so you can still find it there.
You have a very detailed description of the spacecraft and the probe a the mission website.
1) They don't fold out. It looks like a bigger dish you sometimes see on TV vans (I would say 1 to 1.5 meters in diameter). There is a picture on the site above of Cassini with a person standing beside it so you can get a sense of the size.
2) Nuclear. You have this explained in the link above.
3) To communicate with the spacecraft NASA uses the Deep Space Network (DSN), which is basically a bunch of large radio tellescopes that are positioned around the Earth so that they cover the whole sky.
This release of SuSE is supposed to have major improvements for laptop support and wireless, although I don't know anything specifically about the drivers you need.
> NTFS drivers (read only ok)
It has them.

On 9.1 this doesn't work out of the box but I recently set up a Dell laptop for a friend to work at that resolution after a short google.
These guys were theorists. For what they came up with they didn't need an army of graduate students and engineers turning bolts on an accelerator. Fortunately there is still some room for people that just know a lot and are smart enough to do discover things by themselves (of course in the context of other people's work).
It is the people that run the computers that might not be trustworthy. This is also true for all the systems you mentioned. It is not very likely that someone would deliberately make a faulty life support system but you wouldn't need a paper trail to see that the system failed in that case...
My point was that is is highly unlikely that he was unable install Gnome because of a flaw in SuSE. As some other poster also said, YaST can resolve the dependencies for you. I have never had a dependency problem installing something that was provided by SuSE that was not resolved by YaST. Also they have made it really easy to configure what kind of graphical environment you want so I really don't understand what this guy did not to be able to install Gnome (which is basically his only problem). SuSE is a very polished, easy to use and install distro and if he can't install it properly maybe he shouldn't be writing reviews.
This guy just installed SuSE 9.1 without Gnome (his choice) and then complained about not having Gnome and Gnome applications!? I have installed SuSE 8.0 and 8.2 (both home and pro) a couple of times and never had any problems installing Gnome (I prefer KDE but install Gnome just in case). I don't think it's very likely that they would brake YaST so bad that you can't install Gnome. Yes, it complains about dependencies but it resolves them and installs everything you need. SuSE is by far the easiest OS I have had to install (well apart from a bizzare NIC problem...).
KDE 3.2 had some pretty annoying bugs. It's good that they released 3.2.1 so soon - for me it fixed all the problems I was having with 3.2.1 (kmail erratically movin around messages, kget was basically unusable since it crashed so often...) I might be imagining but I got the impression that konqueror starts up a bit faster in 3.2.1. I also just figured out today that the default server response timeout on KDE is large and was slowing down konqueror. Once I made it smaller konqueror was noticeably faster.
I don't think the speed is a distribution issue. I compared speeds of KDE 3.1 and 3.2 on the *same* SuSE 8.2 installation I run at home. I am also comparing it to the dual boot windows I have which is much faster. I don't mind the speed of KDE since it offers so much other stuff but it would be nice if it was faster.
Re:KDE 3.2 well worth the upgrade!

KDE 3.2.1 Released

· Score: 2, Informative
I use kde and really like it but the speed issue is not fixed yet. I was hoping to see this great speedup in 3.2 but to be honest for me it runs the same as 3.1. Startup on login takes the same time. There is some noticable improvement in startup times for some applications but nothing spectacular. Everything else though is great. The menus are cleaned up and there are many small usability improvements.
The hart has it's own, automonous circuitry that runs hart contractions. You need very high currents (as compared to currents in the brain) to mess up the hart.
I had already, through a lot of pain, setup my printer when I upgraded to KDE 3.2 but i just checked the printer manager in 3.2. It looks very good and easy to use. I didn't try to setup my printer again (not that brave) but the interface looked clean and well organized and you can use it to setup a CUPS printer. I guess somebody already "submitted the patch".
I also hate that in the Gimp. I've been using 2.0 for some time now and you can basically use a single window. In 2.0 you can now add different tabs to the same window instead of opening separate windows (for the brushes, for example). You can still detach the tab if you are in a masochistic mood:). I really like 2.0 I have to say. It has some glitches (at least the build I installed) with the selection tool but other than that I was happy with all the improvements.
Earth's field is extremely homogenous. You would have to move very fast to see any significant changes of the field at 60Hz. Also, the amplitude of this apparent AC field would be proportional to the difference of this already small field at the two positions which makes this effect irrelevant.
I didn't check your numbers, but even if they are correct they don't mean much. Earth's field is static. This is also the reason why you don't care about the huge fields in MRI (as long as you don't shake your head in the fringe field in which case you do get dizzy or see stars due to the eddy currents induced in your brain).
What these guys did was put the rats in time varying magnetic field and argue that this affects the transport of iron in and around the cells. The only problem I can see is that the magnetic field configurations from common appliances are nowhere near the field produced by a Helmholtz pair (which they used). I don't know what kind of field strengths you would expect from ordinary electrical devices but they might get farily high near the devices close to the 60Hz currents.
Actually I never quite understood how some of the 32 bit motherboards are advertised as being able to use 8GB. Even if the memory controller could do that how would the CPU address above 4GB?
Well, many calculations in academia are done on "desktop" computers. Some of the calculations done in the lab I work in can easily gobble up more 4GB of RAM. A couple of weeks ago we were looking into our options to address this problem at a reasonable price. Speed would also be nice when you have to cruch that many numbers, but if you don't have the RAM you can't even wait longer to get the results.

That looks like a superkaramba theme running on kde. On www.kde-look.org there's plenty of OSX like docks for superkaramba.

I really like 2.0 I have to say. It has some glitches (at least the build I installed) with the selection tool but other than that I was happy with all the improvements.
In KDE you can just add another panel which autohides and contains only the pager. This part of the "invention" is trivial.
