This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I would argue that "web development" is a specialization of "software development". If you're writing code (PHP, or Perl, or Java), you have a chance of doing "software development." One of "web development's" key differentiators is that it is often done in the context of a web server or application server, and you're dealing with "the web", so wrangling with HTTP becomes important. Good luck!
