In my case I may not have a cap on electricity, but my rate jumps quite a bit if I go over baseline. I've hit over 300% of baseline where I was paying $0.39/kwh. So I am effectively capped at the pocketbook. Oh, and during heat waves they will kill power with rolling blackouts or by remotely shutting down AC units. There are also many places that do cap water usage as well where fines can be levied as well due to water shortages caused by drought and overpopulation.
Nova on PBS had an episode describing how the amount of sunlight hitting the earth has decreased roughly 3-5% or so due to all of the pollution put into the air from countries like China and India with poor emission controls. They said that all of this pollution is actually cutting the effect of global warming in half.
I am in the same boat. There's too many things that still don't work very well in KDE 4.2 that I use all the time in 3.5. I use some KDE 4 apps, but won't switch over until a number of issues are addressed. One of my big beefs is that the task bar won't span monitors in Xinerama mode and the key bindings don't support a number of the keys that work with 3.5.x.
Your comments are utter nonsense, speaking as someone who has implemented equipment with IPv6 support in a device with a relatively low-end CPU.
The CPU overhead is not significantly different than IPv4, even on low-end processors. In fact, I measured slightly higher performance with one computer, a 333MHz Pentium II running Linux 2.4.21 and saw virtually no difference on the embedded device using a 400MHz Freescale 8270.
As far as routers go, most high-end routers have decent CPUs, but more than that, they have dedicated hardware for doing the packet forwarding.
Things like the IP header checksum consume negligible CPU overhead. Gigabit routers usually use hardware designed with IPv6 support built-in. Most high-end routers use dedicated ASICs or network processors which have no problem handling IPv6.
BTW, IPv6 does not use ARP but neighbor discovery via multicast.
The additional overhead of 20 extra bytes per packet is also negligible in all but the slowest connections.
Now home routers typically don't have IPv6 support, but it's not too difficult to add (at least the ones using Linux internally).
IPv6 is already being deployed by some ISPs. For example, Comcast is migrating the control side of managing cable modems over to IPv6 due to the increased address space.
As for meta data, it's a very low percentage of the traffic and there's really no difference between IPv4 and IPv6.
In many areas of the country clean coal won't work since the geology isn't right for storing the captured CO2. Additionally, there currently are not even any working demonstration plants, only talk of plants that could be converted. The sheer amount of CO2 produced from coal is also a huge problem. It would require massive pipelines to dispose of the CO2 from areas that don't have the geology for storing it, and then there's the danger of a fissure opening up somewhere and the CO2 escaping, which would be deadly.
As I see it, the only long term methods of reducing CO2 are renewable and nuclear.
The only reason clean coal is happening is because the government is throwing money at it and all those coal producing states and the votes they represent. There has not been a single demonstration that clean coal actually works.
The graphics were also vastly superior to CGA, i.e. no snow, flickering and it could do 16 colors at 320x200 and 4 at 640x200 (CGA could do 4 at 320x200 and b/w at 640x200). The graphics controller could also be programmed to use the memory for double buffering and scrolling since it used the lower 128k of system memory.
The major draw-back was the chitlet keyboard which was later replaced by a much better keyboard. There were 3rd party adapters to use regular PC keyboards as well.
Also, it did not support DMA for floppy access which resulted in being unable to type while disk access was taking place.
I have found Linked-In to be an excellent tool as a professional. It allows me to keep track of former colleagues and is proving to be invaluable now since I was recently laid off due to downsizing. Linked-in is geared towards professional contacts. It is not a regular social networking site. Most of my former colleagues are on it and it's great to see where everyone is working. It has features like specifying your current job status and leaving recommendations for people.
And they aren't very effective either from all the research I've been reading. They work for a short while until the rodents become accustomed to the noise and they become useless. I even found a government web site where the FTC went after a bunch of the manufacturers years ago for deceptive advertising.
In my research I came across some that use strobe lights and reading about them I can see that those would be much more effective, at least in places where humans don't have to go.
My cats do this with mice. They find them outside and bring them in alive to show me rather than killing them. In this case, they make the problem worse by bringing in mice where there otherwise wouldn't be any.
I've had success with an electronic rat zapper in my attic. You want to use peanut butter and not cheese, though. I don't like the sticky traps. For one they tend to leave a big mess, and two I've watched rats escape from them. The problem with live traps is that once a rat has been caught by one it likely won't be caught a second time.
I'm getting tired of always having to go up there and check it, though, so I'm investigating getting something like this. I just wish they were not so expensive. The cheaper ones I've seen have a limited bulb life though.
The ultrasonic repellant devices don't work very well since the rats acclimate after several days and ignore them.
The performance issue should be fixed now in the latest driver version. It was a known bug and nVidia fixed it. I have no problems with the 180.25 driver.
I have had issues with the VxWorks GCC 2.95.3 on several occasions when the compiler generated incorrect code resulting in crashes and lockups. The C code was correct, but the resulting MIPS assembly was incorrect. Each time, making slight changes to the C code would fix it, i.e. replace a for loop with a while loop. I say good riddance to VxWorks. The memory management in VxWorks 5.4 was atrocious and had to replace malloc with DLMalloc plus add a method of tracking memory usage on running systems (marking each memory block with the task and caller PC) so we could find and fix memory leaks on systems out in the field. The networking was also pretty bad in it.
I recently upgraded a piece of equipment running a Freescale 8270 that does something similar from 2.4 to 2.6.17 and the networking performance improvement was very significant. If you need better performance and lower latency, 2.6 is definitely the way to go.
The old 2.4 kernel had been significantly hacked up as it was to improve performance which resulted in higher latency. The networking interrupts killed the performance unmodified.
We now plan to upgrade two other CPUs from 2.4 to 2.6 after seeing these results.
A lot of hacks were made to the 2.4 kernel that were no longer required for the 2.6 kernel, though I did have to port a couple kernel modules and I modified the 8270 network driver to handle NAPI.
Most white LEDs are pretty poor at rendering color, usually much worse than CFLs. The high efficiency white LEDs usually have a poor color rendering index since they're usually dichromatic, consisting of only two colors of light, yellow and blue. Also, the LED colors often shift with temperature as well.
Wikipedia has a good description of how they work.
I think white LEDs will become a lot more useful for lighting in the future, but they're not quite here yet.
I can think of a number of places on the big island of Hawaii where solar and wind farms could be built and nobody would really care. At least when I visited there years ago there were vast uninhabited areas with only lava fields outside of Kona. I'm also sure there's some good places to build up around the saddle and on Mauna Kea.
I know there's already some windmills near Southpoint on the big island.
Not all of Hawaii is a tropical paradise. There are large areas on the big island that get little rain and are uninhabited that would work quite well.
The Kindle can also read DOC, PDF, RTF and other formats as well with the conversion service, which I believe is free unless you upload it to your Kindle via wireless. It also handles MOBI and text files. You can add your own documents and annotate any books on there, plus if it's lost or stolen you do not lose your content since it is backed up.
I use whatever works. For me, the nVidia closed source driver works better than any open source driver.
I struggled for months with ATI and cursed it every few minutes when it would screw up the text in my editor (closed source driver). By the time the open source driver came out I had already dumped the computer for one with an nVidia card because the drivers just work, out of the box. Intel wouldn't recognize the monitor, ATI would constantly screw up, if I could even configure it for the monitor, but the nVidia one just worked. They provide better features than any other driver I've seen, both open and closed source, and their performance has always been better.
Similarly with photo software. I use the Linux version of Bibble Pro because I have yet to find an open source equivalent that is anywhere close. Gimp doesn't come close in its RAW handling or ease of use for workflow processing.
I've tried to use ATI but I had way too many problems and terrible performance. Similarly with the open source Intel drivers which did not work at all.
Open Source has many benefits, but when it doesn't do what I need, I'll pay for something that does.
I write software, both open and closed source and am currently hacking on the Linux kernel. I think both have their place and neither side is perfect.
This is one of the killer features, plus C-x 5 2. Both of these allow me to view multiple sections of the same file, basically multiple views. This is what caused me to adopt Emacs almost 20 years ago because my previous programming editor did this. I'm constantly editing several sections of the same file. Another common use for this is if I need to look up a tag, I'll just split the window then M-. to show the tag in the other window without having to leave the file I'm working on.
It's actually not difficult. Turn on reverse path forwarding and packets with source addresses that don't match their subnets will be dropped. Furthermore, they can match a source IP with the MAC address assigned via DHCP. Any halfway decent router should support RPF at least, and most should support access control lists.
With DSL and dial-up, RPF is even easier since there is usually only one IP address per connection. With cable modems it can be a bit more complex, but they can also filter in the modems themselves and I'm sure the head end can also do filtering.
Usually circuit boards will be fine if they are rinsed quickly with distilled water and dried. For drying I like to take an air compressor and blow all the water out then have it air dry with warm air blowing against it. The air compressor helps get the water out from under surface mount parts. Rinsing in pure alcohol might also help. Rubbing alcohol that you buy at the store typically contains between 10 and 40% distilled water.
However, if the boards stay wet for a long period of time then you will have problems with corrosion and it's no longer really recoverable.
You will want to completely disassemble everything. You also will probably want to clean the inside of the cabinet and any displays to get rid of water marks.
A projector might be ruined if water got into the optics since many components do not like water.
Speakers also don't like water very well. Many speakers have a port to help with bass and are often filled with some form of batting. Many are also made of particle board or similar materials which also do not do well when wet.
DVD/CD players are also probably toast since the optics are a bit delicate and do not take kindly to water.
I sometimes have to travel with a couple large plastic cases to O'Hare. To make sure it doesn't come apart I tape the lid on with lots of duct tape. It has never been opened, I think in part because it's a real pain in the ass to cut or remove all the duct tape.
It's pretty bad with Linux too. I managed to get Korganizer to work, though read only. I know someone at Apple who's working on supporting Exchange, but many of the protocols are undocumented and proprietary and thus must be reverse engineered.

I second this. If you can see the hole stuff it tightly with steel wool. I had a constant problem until I used steel wool to plug the entry point.

At work I have nothing but trouble trying to reliably use our Exchange server with Linux for calendar support.
