Best RxJava links: map, flatMap, concatMap, and more

As often happens, I have about 50 browser tabs open, and in an effort to close some of those down, these are some of the best links I found while working with RxJava a week or two ago:

Letting Google know about broken links I've fixed

Last night I spent some time going through my Google Webmaster's account, and found a listing of a large number of links I had broken on this website, largely because I removed the old, stale "directory" I had on this site.

This is a terrific book for Swing/GUI developers , and it's full of links to great Swing resources on the internet.

The link popularity of OpenSSO, WebSeal, and web tools

I've been working on a single sign-on project lately, evaluating both OpenSSO and IBM's trio of TIM, TAM, and WebSeal, and I noticed that Google has only 32,000 links to real WebSeal resources. By contrast, even as a young open source project, OpenSSO already has over 100,000 links.

Out of curiosity, I decided to google a variety of web languages and tools, and here are my search results:
