I'm amazed when I watch my students ...

You're in an ideal position to have perspective on this, since you have a history of contact with students.

What trends are you seeing in their approach to debugging?

    Well, for one, I deliberately don't waste time teaching the Perl debugger in the llama course (or in the llama book). Frankly, if you need to invoke a debugger on a 10-line program, you should not be a programmer.

    So, I see two kinds in the llama class. People who work like me, and people who don't. Most of the people who work like me (little snippets, until it works) get the job done quickly. Most of the people who don't seem to get into cut-n-paste frenzy, and then unable to continue with the later exercises where we talk more about concepts and show fewer working programs.

    I'm rethinking the strategy for the PROM course (packages references objects modules), simply because the "x" output from the Perl debugger is durn useful at just seeing what you autovivified. I have a "long" version of the course where I teach the debugger toward the end, but I've ended up demo-ing it in the middle instead far too often.

    Personally, my use of the debugger is limited to "perl -debug", to try out one line snippets interactively. I remember that neither Larry nor I had enough experience with the Perl debugger (even though he wrote it!) for the first Camel, and that's why there's very little on the debugger in there. Neither of us use it!

    I just realized that this statement taken out of context could send me up the river for a while.

    This morning, I found that amusing. {grin}

[choroba]: Corion a bug report?
[choroba]: I have no idea :-( I used to post to, but they don't seem to feature "private" pictures in the free version now
[Discipulus]: dazz i'm not an experts but i think it would be possible
[Corion]: dazz: I think Image::Magick can "read" from an in-memory filehandle
[Corion]: choroba: No, some general admin discussion of how to handle (company) user accounts
[Discipulus]: might be it is necessary to pass the pic data like MIME::Base64:: encode( data..
[Discipulus]: if you have a jpeg data: or as wise Corion said IM ca n read directly your handle
