Comment Carnot Efficiency (Score 1, Informative) 123

Like other posters have said, converting the electricity to heat is nearly 100% efficient. And with a temp of 500C, the carnot efficiency is (773K (hot) - 293K (cold)) / 773K = 62%. This is the maximum efficiency possible. Newer supercritical coal plants operate in this same temperature regime and are 40-45% efficient.

Submission + - HackingTeam's Global Export License Revoked

An anonymous reader writes: You might remember HackingTeam from an epic data leak back in July 2015. Now, the Italian Ministry of Economical Progress has revoked HackingTeam’s licence to export their Galileo remote control software abroad, two years before it would expire, on April 30, 2018. Until the situation changes, HackingTeam will have to ask express permission for every single commercial operation that involves the sale of their Galileo system abroad.

You seem to be describing a class of problems known as "embarrassingly parallel", as in "I'm embarrassed when I can't solve this problem in parallel." There are other parallel problems that are more difficult and that require actual brainpower to solve. Perhaps you just haven't run up against one.

Comment Re:Good free command line tool (Score 3, Interesting) 440

I recently had this problem and solved it with finddupe (http://www.sentex.net/~mwandel/finddupe/). It's a free command line tool. It can create hardlinks, you can tell it which is a master directory to keep and which directories to delete, and it can create a batch file to do actually do the deletion if you don't trust it or just want to see what it will do. Highly recommend. In any case, 5 TB is going to take forever but with finddupe you can be sure your time is not wasted, unlike one of the free tools that analyzed my drive for 12 hours and then told me it would only fix ten duplicates.

I tried this vs. Clone Spy, Fast Duplicate File Finder, Easy Duplicate File Finder, and the GPL Duplicate Files Finder (crashy). (Side note: Get some creativity guys). There's no UI but I don't care. It doesn't keep any state between runs so run it a few times on subdirectories to make sure you know what it's doing first then let it rip.
