    Things I Learned From Having Users Things I Learned From Having Users Presentation Transcript

    • Things I Learned From Having Users
    • Dave Cross [email_address]
    • It's 10 Years Since I Got A CPAN Account
    • April 29 2000
    • Array::Compare 0.01
    • It's a pretty pointless module
    • Comparing arrays using a ridiculous algorithm
    • My second module on CPAN was Symbol::Approx::Sub
    • There may be a theme developing here
    • I now have 24 distributions on CPAN
    • Array::Compare AudioFile::Info AudioFile::Info::MP3::ID3Lib Audiofile::Info::MP3::Info AudioFile::Info::MP3::Tag AudioFile::Info::Ogg::Vorbis::Header AudioFile::Info::Ogg::Vorbis::Header::PurePerl Calendar::Simple Guardian::OpenPlatform::API Net::Backpack Number::Fraction Parse::RPM::Spec Perlanet Symbol::Approx::Sub Template::Plugin::AudioFile::Info Template::Plugin::RPM2 Template::Plugin::XML::Feed Tie::Hash::Cannabinol Tie::Hash::FixedKeys Tie::Hash::Regex WWW::Shorten WWW::Shorten::Qurl WWW::Shorten::Qwer WWW::Shorten::SnipURL
    • Most of them have tiny numbers of users
    • Having few users is good
    • Users are a problem
    • Users report bugs
    • Users suggest enhancements
    • Users expect you to listen to them
    • Writing unpopular modules is good
    • You can release what you want
    • You can release when you want
    • You can completely change the interface
    • (Users don't like that)
    • On the other hand
    • Users make suggestions that you would never have thought of
    • Users use your code in new and interesting ways
    • Users test your code for you
    • Users report problems
    • Users supply failing tests
    • Users write patches
    • Users are good!
    • Embrace your users
    • But!
    • Popularity brings problems
    • Too many active users
    • Too many bug reports
    • (Why are you releasing buggy code?)
    • Too many bug reports
    • Too many bug reports
    • Too many enhancement requests
    • Use the tools
    • CPAN has a great infrastructure
    • Distribution is handled for you
    • Testing is handled for you
    • Cross-platform testing is handled for you
    • Bug tracking is handled for you
    • Every CPAN module gets its own RT queue
    • rt.cpan.org
    • Add that to your documentation
    • To report bugs in Perlanet, please use the CPAN request tracker. You can either use the web page at http://rt.cpan.org/Public/Bug/Report.html?Queue=Perlanet or send an email to bug-Perlanet@rt.cpan.org.
    • All bugs get automatically stored in RT
    • It won't work
    • AUTHOR Dave Cross, <dave@mag-sol.com>
    • To report bugs in Perlanet, please use the CPAN request tracker. You can either use the web page at http://rt.cpan.org/Public/Bug/Report.html?Queue=Perlanet or send an email to bug-Perlanet@rt.cpan.org.
    • TLDR
    • AUTHOR Dave Cross, <dave@mag-sol.com>
    • Install the Redirect add-on for Thunderbird
    • Install the Redirect add-on for Thunderbird * Dave's Top Tip
    • Or use the bounce key in Mutt
    • Send your own bugs to RT
    • Use RT to remember everything you need to do to your modules
    • Use RT to remember everything you want to do to your modules
    • Some examples
    • Example 1: Moose
    • Moose is good
    • I started to Moosify my modules
    • Remember Array::Compare?
    • The module that no-one used
    • I got a bug report
    • Bug #49270 for Array-Compare: Remove the use of Moose
    • Padre project was unhappy
    • Moose was slowing their performance
    • I thought about it
    • I blogged about it
    • Other people blogged about it
    • In the end I did nothing
    • Source code is on Github
    • Feel free to fork it
    • Moral:
    • The user is not always right
    • Example 2: Net::Backpack
    • Backpack from 37 Signals
    • Personal information manager
    • With an API
    • Net::Backpack
    • It's a big API
    • I got bored
    • Release early Release often
    • Released a partial implementation
    • Someone found it useful
    • Sent a patch completing the implementation
    • Yay neshura!
    • Example 3: Perlanet
    • Perlanet is a web feed aggregator
    • Wrote it because I didn't want to hack Python
    • And Plagger was too complex for me to understand
    • So Perlanet is really simple
    • Too simple
    • Users have weird use cases
    • Users have weird use cases
    • Users have unexpected use cases
    • Alex Kapranoff (kappa)
    • perlplanet.ru
    • Cyrillic
    • Кириллица
    • Lots of Unicode bugs
    • kappa didn't complain
    • kappa forked Github repo
    • kappa fixed the bugs
    • kappa sent a pull request
    • kappa++
    • Planet Iron Man
    • Originally used Plagger
    • Wanted to switch to Perlanet
    • YAML configuration
    • Simple
    • Doesn't scale
    • North West England Perl Mongers
    • Hackfest
    • Many improvements
    • More subclassable
    • Github pull request
    • Everybody wins
    • In summary
    • Writing software just for yourself is fun
    • Writing software for users is better
    • Seeing your software being used is great
    • Getting feedback about your software is great
    • Users supply bugs
    • Users supply patches
    • Users supply new ideas
    • Users supply insight
    • Users appreciate your work
    • But best of all
    • Some users show their appreciation...
    • By buying you beer
    •
