Perl 說明文件
要查 Perl 內建的 function, 就到 Perldoc 去看.
Perl Functions 就可以看到了.
平常命令列下 可以下 perldoc -f localtime,
或 perldoc -q keyword 查看所需要的 function.
其它進階的 module, CPAN 這些一樣都在 Perldoc 尋寶吧 🙂

寫 Blog 有助於工作十個理由

寫 Blog 有助於工作的十個理由
轉載自 Ten Reasons Why Blogging is Good For Your Career

  1. You have to get noticed to get promoted.
  2. You have to get noticed to get hired.
  3. It really impresses people when you say “Oh, I’ve written about that, just google for XXX and I’m on the top page” or “Oh, just google my name.”
  4. No matter how great you are, your career depends on communicating. The way to get better at anything, including communication, is by practicing. Blogging is good practice.
  5. Bloggers are better-informed than non-bloggers. Knowing more is a career advantage.
  6. Knowing more also means you’re more likely to hear about interesting jobs coming open.
  7. Networking is good for your career. Blogging is a good way to meet people.
  8. If you’re an engineer, blogging puts you in intimate contact with a worse-is-better 80/20 success story. Understanding this mode of technology adoption can only help you.
  9. If you’re in marketing, you’ll need to understand how its rules are changing as a result of the current whirlwind, which nobody does, but bloggers are at least somewhat less baffled.
  10. It’s a lot harder to fire someone who has a public voice, because it will be noticed.
