Resources for learning software development

[This was originally posted at http://timstall.dotnetdevelopersjournal.com/resources_for_learning_software_development.htm]

I was thinking the other day how many different resources are out there to help someone learn software development. There's something to appeal to almost every style:

1. Books
2. Reference docs
3. Articles
4. Webcasts
5. Podcasts
6. Virtual labs
7. Newsgroups, discussion forums
8. Live Events
9. Professional Groups
10. Blogs
11. Training (class room setting)
12. Sample code - quickstarts
13. Sample code - real projects
14. Tutorials & Walkthroughs
15. Local class at community college
16. Bachelors or Master’s degree
17. Teaching others (forces you to learn it)
18. Write your own blog
19. Personal pet projects
20. Open source projects
21. Your coworkers. A physically present person, who can look at your machine environment, can be the best way to learn.
22. Private tutor – perhaps for introductory topics where such tutors are much more abundant.
23. Certification

Any others that you've personally found helpful?
