Could Thorium be the answer to clean nuclear power?

New age nuclear | COSMOS magazine

This is a really long article, so you may want to skip to the end if you want to get right to the point.   What’s so cool about Thorium is how it breaks down as opposed to Uranium.  It’s waste products also remain dangerously radioactive for only 5% of the time of Uranium byproducts. (500 years vs. 10,000)  As if that wasn’t enough, there is also the possibility that Thorium-based reactor technology could be used to “incinerate” the waste products of traditional nuclear reactors, cleaning up much of their mess.  Oh yea, and the design is incapable of a meltdown. (at least the ADS type…)

*THE* classic Unix horror story

*THE* classic Unix horror story | WSU Linux Users Group

If you’ve never used Unix or Linux, you may want to pass on this one. For the rest of you, this is a reminder of why the line “Think before you type” is presented to first time users of the sudo command. At some point along the way, just about everyone on a *nix system has a minor encounter with rm’s nefarious -rf flags. Thankfully mine was nowhere near this severe.

I happened upon a similar article on reddit after the one above that details how to recover files on a Linux EXT3 partition.  Like the developer mentioned in the article, this is something up until now I believed to be nearly impossible.

So, the moral of the story:  NEVER, EVER use “rm -rf,” unless you have absolutely no alternative.  (and in that case, think long and hard before hitting enter)  “Think before you type;” those are words to live by.
