Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

Need for speed

When it comes to driving, I'm a rather slow driver. I can parallel park with my eyes-closed, merge in traffic easily, but I really don't enjoy driving fast (Mind you, I take public transport these days). But when it comes to squeezing performance out of a system, I guess I'm much more attracted to the idea of things running fast. The redis attraction is therefore quite obvious. In-memory database. It doesn't get much faster than that.

Bumps on the road

It was rather surprising to come across speed issues with redis, and fairly early-on with our project. At kenHub, we are building an anatomy learning platform. The platform must adapt to each and every student, and present them with the best question for their level. To do this, we must store statistics for each and every anatomy term for each user. Redis was a natural candidate for this. Quick access to read/write individual records allows us to u
