Re: A New Lesson For My CGI Course

[dragonchild]

• Copyright symbols, AFAIK, should be superscripted. (When you speak of AD&D, for instance)
• Why should you remove fatalsToBrowser in production? I didn't immediately make the connection when I first heard it and I'd been programming webapps for over a year by then ...
• Instead of &roll, I'd say roll(). That's how I see functions described in texts about other languages.
• I usually see a hash-of-hashes is referred to as a HoH, not hoh.

Thanks for the feedback. I'll get some of that fixed.

As for "fatalsToBrowser", that's part of the reason why there's a (limited) search box in the upper right corner. Enter 'fatalsToBrowser', select "users.easystreet.com" and click enter. The very first link it displays is for my third lesson. In that lessson I cover security and I discuss that very issue. My course really is a course just like you would have in school: lessons are progressive and build on one another. I suppose that should be more clear.

Update: Those are fixed, with the exception of how to refer back to my previous information regarding fatalsToBrowser. I'll have to give that some thought.

The search box, topright, and the LeftSideBar links to previous lessons seem to me to be adequate, but -- FWIW -- perhaps in-line links to specific previous discussion might have occasional merit?

Hard to know, of course, what criteria to use for backrefs of that sort. Too many = clutter and additional filesize + writing time for you.

Observations from one who owes much of his understanding of CGI to your course. ++!

"Why should you remove fatalsToBrowser in production? I didn't immediately make the connection when I first heard it and I'd been programming webapps for over a year by then ..." What I've always heard is "because an error message may give an 'evil hacker type' too much information". Someone else can probably elaborate as to how valid that is, I don't do much CGI/web stuff. (A rails app every now and then, that's it).

That is the exact reason, but it's a reason that isn't immediately obvious to many people. That's why I'm suggesting Brother Ovid make it explicitly clear as to the benefit.
