mongod won't start.

If you've tried sudo service mongod start and it says it started but didn't, or maybe gives you a cryptic error.. consider removing the lock file at /edx/var/mongo/mongodb/mongod.lock and try again.

No locks available.

So, when running some tests, I got the error "No locks available". This post suggests NFS. The actual fix appears to be to restart rpcbind sudo service rpcbind restart which hung my vagrant VM. When it restarted, I got the error below, but things seemed to work as I wanted and I'm slowly backing away.

Code Review

A guide for reviewing code and having your code reviewed.

Peer code reviews are the single biggest thing you can do to improve your code - Jeff Atwood

Purpose

Code review is an important part of a team's development process. It helps to:

disseminate knowledge about the codebase/technology/techniques across teams
increase awareness of the features being developed

So I was writing an article on screen scraping and one of the things that came up is "How do you mitigate against screen scraping?" I think this is actually in interesting question, which brought up the idea of a side project that maybe someone else has time for.

The idea is that to prevent screen scraping, the page being scraped must be mutated as to break a scraper. To do that, you could do things like alter selectors of css resources and html (for instance, changing all ids of "signupButton" to "sarah-goldfarb") or change the structure of the page. Maybe it also mutates the structure of the DOM.

A small node proxy that does this around streams would be particularly cool.

Things you're likely to learn:

More about CSS selector precedence. Which selectors can you easily mutate? Which are harder? Are there examples of selectors which you can't mutate?
What can XPath do? XPath is a mechanism for querying tree structures (notably XML). If you were g
