# NOTE: jhead can be used too
# see http://www.sentex.net/~mwandel/jhead/
jhead -exifmap myimage.jpg | grep Ori

# 2/ Remove EXIF orientation
#    i.e. rotate the image accordingly and reset the orientation
#    flag to 1 (default, i.e. origin = TopLeft)

I think you have to open the objects and open your methods. I think that
this idea of hiding in layers of abstraction everything about the
details has, in fact, pretty much run its course now. I think the idea
that we can make these sorts of black box devices that we only know
about the shell of and have no knowledge of the internal workings of is
in fact a deep mistake. Because it turns out that in order to be able to
reason about how the system is actually working, we have to have
knowledge about what is inside the black box.

Decoding Base64-URL without padding

1) Add padding

Divide the length of the input string by 4, take the remainder. If it is 2, add two = characters at the end. If it is 3, add one = character at the end.

You now have Base64-URL with padding.

2) Translate to Base64

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.
