English for Electronics and Telecommunication (Tiếng Anh chuyên ngành ĐTVT)

Sorry to post this mundane question here, but I need help!

I have to do a 1 hour Software Best Practices Training for some
programmers in my company. Audience are Freshers to couple of years
experience guys.

Can you guys please suggest some relevant topics I can cover?

I could think of the following:

1) Importance of following coding standards, indentation
2) Proper naming of files, variables, functions, classes, tables.,
columns, views and all other artifacts
3) Layer your application - each layer must address a specific
concern
4) Abstract common stuff into reusable utility classes

Any help will be greatly appreciated
