Fix broken links

[tfausak]

This is routine maintenance. It picks up where #107 left off. I added a script to check for broken links: fcbe834. Running the script gave 24 broken links:

Some of those might be false positives. The "001" status code means there was an HTTP exception. The "999" status code isn't my doing, so either LinkedIn is returning some weird stuff or the HTTP client is bungling something.

I fixed some of these. It doesn't really feel worth it to fix all of them. For example, everything on lwm.github.io is simply gone. I may need to start archiving content when I link to it.
