Interesting read on request versus response rate limiting.

2013-01-11T12:28:00Z

We've recently been the reflection point in a DNS-based reflection+amplification attack. We implemented some rate limiting to prevent it, and as part of my research on this topic I found this discussion to be fascinating. In particular, the trade-offs between request rate limiting and response rate limiting... It's about half way down in this dns-operations thread on "DNS ANY from Amazon".

SVN directories

Just a note on something I've noticed in Ubuntu Quantal... It includes Subversion version 1.7.5, which has this compelling feature: The .svn directories have been merged into a single directory at the top level of your checkout. So no longer are the subdirectories littered with .svn directories. Makes script and find commands of sub-sections of the repository easier.

Skeleton for testing Python code.

Thanks to Bill Tucker and 2011's Code Retreat that he put on, I've become quite the convert to testing. I knew I should be doing it, but I never found the time to become really comfortable with them until Code Retreat.

However, especially when I was starting, I found I really needed some examples and wanted some boilerplate I could just drop in place. At the Code Retreat I had just recently come back across an entry I made on my personal Wiki that had some examples. Since then I've expanded on them and today I included some examples of testing Bottle web applications (I still totally love Bottle by the way).

I've create a github account that has these examples and related code such as a "Makefile" which automatically runs the test. You can find it at https://github.com/linsomniac/python-unittest-skeleton. I hope you find it as useful as I have.
