git commit -v gives you the diffs provided you don't also use -m. Personally, I find -m to be a dangerous flag for commit for exactly the reasons you described not mention its hard to really do detailed multi-line commit messages with -m.

Moving a file (within the same file system) is an atomic operation on most file systems, but writing data is not.
If you don't do this and you're overwriting a file directly and the write fails for some reason, the data from the old file will be gone and you'll only have a partially-written new file in its place.
This also helps with systems that continuously poll files and watch for changes. If you have, say, a compiler watching your file, you don't want it to start compiling a partially-written version of your file and give you some strange error just because it happened to poll before the write finished.
>Both Applied Cryptography and the Handbook of Applied Cryptography are great resources, although they're a little dated now. ... Step one is to read Cryptography Engineering. This is not optional. Read it. It is a fantastic book that details how to use cryptographic primitives.
It seems kinda superfluous to mention Applied Crypto when the real reco is to read Cryptography Engineering. I'd almost wonder if it would be better to direct people away from Applied Crypto...
Personally, I found Applied Cryptography to be so-so at best. Practical Cryptography was a breath of fresh air in comparison.
Yes. Recommending Applied Cryptography is usually a warning sign that the person doesn't know what they are talking about. In this case the rest of the advice is reasonably sound for an engineer that wants to start learning the fundamentals of modern cryptography.
If were talking about graphics card rigs, well I guess could attempt to re-sell them to gamers and the like to attempt to get some money back out of them (although, in the end probably still a loss unless you covered the purchase+power/cooling+maint costs in mining with them)
ASIC BTC mining hardware, I don't think can be re-purposed.
