• Hidden features of Perl

    There's an interesting little thread at Stack Overflow on Hidden features of Perl. Go on over and add your favorites.

  • Developer optimization redux

    Users are crucial to open source projects. Without them we have no reason to release publicly, and without refreshing the ranks of developers with users who join the fold, our projects die. Users are our customers, and we can't afford to treat them poorly. When a user wants to go the extra mile to help us as developers, turning him or her away is a grave misstep.

    Here's an example. Andrea discovers a problem in PHP's database handling, where calling a certain function incorrectly causes a segfault. The bug isn't a work-stopper for her, and the fix is simple: Call the function correctly. Still, it's a segfault, and she figures the PHP folks will want to know about it. It also doesn't help her confidence in the tool that calling a function incorrectly segfaults. Being a good open source citizen, she decides to report the bug.

    She's already spent the time figuring out the problem, and she reduces the code to a single, repeatable example, that shows exactly how to make the code segfault. "This should help them track it down," she thinks. She's spent an hour on this detour in the middle of a project for work, but knows that open source relies on bug reports to get things fixed.

    She dutifully checks bugs.php.net, and finds nothing that matches, so she goes to submit the bug. Unfortunately, the PHP site will only accept bugs against 5.2.6, instead of 5.2.5 that she is running. This leaves her with three choices:

    • Upgrade to 5.2.6 on a test machine, and test out her problem. She knows not to upgrade a production box so cavalierly.
    • Find someone using a similar install to see if that person will test it for her.
    • Submit the bug against 5.2.6, effectively lying but not spending any more of her time.
    • Throw up her hands and say "Screw it, I've got work to do."

    That's what happened to me, "Andrea", the other day. I wrote about it in a frothier Perlbuzz article the other day. I wish that my frustrations with PHP hadn't overshadowed my point about community building, so I'm trying again here.

    What about the users?

    My frustration in PHP's approach, and they're certainly not the only community to do this, is that the emphasis is in optimizing the time of the PHP developer who has to deal with bugs. "Who wants to deal with bugs that have already been fixed?" goes the logic. I imagine someone setting up the PHP bug database saying "We need to put something up to make sure that we don't get annoyed by bugs that have already been fixed." I can understand that motivation. As someone who answers questions in #perl about WWW::Mechanize all day, I can certainly empathize with not wanting to deal with pointless comments.

    And yet...

    Nowhere do I see any discussion of how the user sees the interaction. I doubt anyone considered the reaction of the user who is told "Sorry, you're not able to submit your bug report that you worked to get together to send to us." Instead, debate about the original article is from the point of view of the beleaguered developer, having to deal with those darn users, contributing their bug fixes.

    Yes, I understand that plenty of people submit bugs that aren't bugs, or that have already been fixed. Perl's bug reporting system is wide open, and I've closed my share of tickets in RT that weren't really bugs. But I'm OK with that.

    How long does it take to close tickets that aren't right? Compare that cost to the cost of losing a valid bug report. Or worse, alienating a potential friend of your project.

    In everything we do when working on projects, we need to remember there are real users, real people at the other end that are the core of what we do.

  • Writing a crawler with WWW::Mechanize

    Stefan Petrea has written up a summary of his building of an MP3 website crawler using WWW::Mechanize and an RDBMS. It's a good write-up, and good overview of the issues of crawling beyond the obvious "open a page, get the links, follow the links.".

  • Index of online articles from The Perl Journal

    brian d foy has put together an index of articles published in The Perl Journal from 2003 to 2006, all available on the web.

    A lot of the articles are out of date, of course (nobody needs my 2004 OSCON roundup, do they?), but others like Simon Cozens' Ten Things You (Probably) Didn't Know About Perl still stand up today.

    Check out the list, and please post back here about the most useful article you found.

  • Announcing “The Working Geek”

    I started a new blog a while ago called The Working Geek, devoted to work issues of interest to techies of all stripes who work for a living. Topics have included how to speak Manager, personal networking and closing the deal at a job interview.

    I'm going to be posting much more as I approach completion of my book Land the Tech Job You Love: Why Skill and Luck Are Not Enough to be published by Pragmatic Bookshelf. Bits of the book will probably make their way into blog posts, and I'll be posting more about work and tech articles that I see.

    I hope to see you there. For convenience and so you don't have to leave the comfort of your newsreader, here's the feed.
