I suggest that this is done to children (especially noisy ones) on airplanes, so study radiation doses from cosmic rays.

But can it measure the harm done by fear of radiation?

Looks like there are some parts (MPEG decoding) that will never be open. But there's a plan to make a open source firmware that is sufficient to boot.

Libreoffice supports Appleworks documents. Maybe she could migrate.

If you open blender on a fresh install you see a 3d view of a cube, and nothing that looks much like a time line. I tried dragging a video file into various bits of the interface and nothing happened. A bit of hunting finds me a 'video sequence editor', that sounds right, but when I drop a clip on it says "Error: file '/foo/bar.mp4' could not be loaded". Useful. Ok, so lets assume that it actually meant 'I don't have a codec for MP4', so i'll try a webm. now I have a block with the name of my file on the time line. But there is no viewer in site. If I press play then a green bar moves across the time line, but I see nothing.

Now I know that if I sat down and read the docs I could make a whole film using blender. But it is not the user friendly video editor that pitiiv is aiming to be.

I consider fracking to be just as bad as all other fossil fuel extraction, which is pretty bad.

Ubuntu still as the 0.15.x series. You should have a look at the recent improvements in 0.92. There is a PPA https://launchpad.net/~gstream...

I think pitivi is aiming to be usable for a different set of users than blender. Pitivi lets you just drag video clips into time line without worrying about resolutions, frame rates or codecs. Achieving the same process in blender requires quite a bit more work.

Vim and emacs are great tools, but it does not mean that we don't need gedit and kate.

While Cinelerra is very capable, it also seems to be an unmaintainable code dump. The community project can just about get it in a state that it builds, but I am not aware that they have added any features to it. IIRC the community devs though it would be better to start again from scatch, with a project called something like Luminara, but I can't find much about that now.

On the other hand Pitivi is build on a solid base of libraries that are used widely in other peices of software. Even if pitivi were not to succede then it would have created the tools for other people to build an editor. It also provides a base of libraries for experimental editors like Nova cut.

They could probably solve this by giving people free pizza

(On a serious note, why does it take a PR scandal to make a fatal explosion at an gas well newsworthy?)

> Nucelar power has problems and if we were to use it as much as we use fossil fuels, it would cause the same problem.

Nuclear's problems are vastly exaggerated. There are industrial accidents and oil and gas explosions every week that have more fatalities than the Fukushima disaster. Passive safety features in modern designs make them safer still, and that's before fancy designs like subcritical reactors. There are methods of destroying nuclear waste (transmutation) or using it as fuel. People worry about long half lives of isotopes, but that ignores that pollutants like lead or mercury effectively have infinite half lives.

Nuclear certainly scares people, but that does not mean that it is dangerous (relative to any other method of power generation, or any other industrial process).

try calculating how massive those battery banks need to be and how much they will cost.

Nuclear output is not varied for practical reasons, not fundamental limitation.

All current grids with nuclear also have fossil fuels. When demand drops you turn the fossil fuels down, because that saves fuel and fuel dominates the cost of fossil fuel power generation. If you turn the nuclear plant down you don't save any money, costs in nuclear power are dominated by construction, other costs are pretty much independent over whether you are generating power or not.

If you had a grid with only nuclear, then you would either add the capability to load follow into your nuclear plants or you would solve energy storage.
