Hat Tip at Frederick Cheung
I admire the public work of Frederick Cheung.
He for example has been giving first-rate help at the rubyonrails-talk mailing list for a long time. Giving support in mailing lists, IRC, or Usenet is not something all people are able to do at that level. Of course you need to be correct and give quality answers, but also you need to have true respect for any question, of any level, and you need to have an intuitive way to guess the level of the OP from a few clues in his wording to tailor your response appropriately. That comes from a genuine willingness to help, to contribute, and from other skills not everyone in public forums have. Excellent job there.
Frederick has been also an important contributor to the Rails core. His work there ranges from small patches, to the entire non-trivial rewrite of eager-loading that saw the light in Rails 2.1.
In addition, he has started a series of articles in his blog that cover fundamental Rails stuff in-depth. For example, everyone knows params in Rails, but I think any developer, no matter he's an apprentice or an expert, should read this recent article.
Keep up the good work Fred!
