How about doing anything that takes a long time and you don't want to remain logged in for it to complete? For example you are running a standard program that is going to take hours or even days to process some data, so you redirect stdin to
There is already a well established mechanism for cleaning up background processes, i.e. the SIGHUP signal. And there is already a mechanism for explicitly stating that you don't want a process to die when you log out, and that is the shell's "nohup" command (which blocks the hangup signal that is sent to the process when the user exits).
And in what way does this new mechanism "enhance security"? Running something in the background after you log out doesn't give you any more privileges than if you remained logged in.
Why do the systemd folks think they need to keep reinventing the wheel? This feels like a solution in search of a problem.
Right, but the other side of the equation is not zero. Coal fired power plants, and the associated mining is responsible for the vast majority of mercury in our food chain. During normal operation, the effective radiation released from coal fired plants are ~100 times that of a nuclear plant. Combustion of fossil fuels produces air pollutants that lead to increased cancer risks and statistical increases in related deaths. Combustion of fossil fuels also are a major source of greenhouse gases.
Then note that the Fukushima accident was close to a worse case scenario, i.e. a major earthquake, followed by a tsunami. Even then, better planning could have prevented this disaster. The safety standards in place at Chernobyl were so ridiculous it's not even worth considering when it comes to accessing nuclear power risks. Lets learn from our mistakes and make improvements, rather than throwing in the towel and increasing use of fossil fuel power plants.
I applaud the view of France, who never wavered in their pursuit of nuclear energy, as opposed to Japan and Germany who overreacted to the situation. I think both countries will eventually regret the path they've taken. I'd certainly like to see the U.S. pursue nuclear energy, since it is the only practical clean energy source that addresses the issue of base load, other than hydroelectric plants, which have significant limitations in where they can be installed.
I'm all for other clean energy sources like wind and solar, but anyone who thinks we can move to them for all our energy needs is living in a fantasy world. The only way that can happen is with unrealistic breakthroughs in storage technology, not the steady increase in storage capability that we've seen over the last 100 years. Stop reading and believing all the "major breakthrough" stories posted to Slashdot regarding this. Inevitably they turn out to be false, or just another step on the same progression we've seen over the years.
Backed up the system lately?
