In Opera Software we use Perl extensively. From internal systems to high traffic web sites and browser-integration services like Opera Link and Opera Unite. Most of them are mission-critical systems, up and running 24x7.

2. Geek company We make a browser, but not only Engineering-driven Most of Opera employees still work in Eng Very smart people I am an exception Opera Software

3. Opera browser C++, huge number of platforms Opera Mini client - server J2ME, C++, Pike maybe you have it on your phone Opera Turbo C++, Pike, speed up page loading Opera products

4. C++ Kingdom Perl Republic Python Dictatorship Pike Islands

11. ok, great, but...

12. Very few people, but very noisy Usually young people Experienced developers don't care Tendency to generalize about Perl and Perl folks... Perl “bashing”...

14. Python getting more and more popular “ They just know Perl, that's why they stick to it” “ Perl is not suited for large applications” “ Perl is a write-only language” (ever heard this?) “ Perl sucks” “ No interesting jobs” Perception

15. We know what the reality is: Perl runs everywhere (and I mean everywhere) Large or small-scale applications … Python code can be horrible too... Python projects can fail too... Reality

16. Understand better how Perl is really perceived and possibly why Expected 10 answers and some boos Got lots of answers (and some boos ) Survey: Perl in Opera Software

17. Survey: Perl in Opera Software Most common reason for “Perl is awful” Syntax is too complicated Most common reason for “Perl is great” Syntax is flexible Make it an expressive language

18. Survey: Perl in Opera Software Most people that complain about syntax have none or very little experience in Perl

19. Survey: Perl in Opera Software 70% CPAN is an extremely valuable resource

20. Survey: Perl in Opera Software 1% Strawberry Perl users

21. Varies greatly “ Legacy” systems We're trying to build a “Quality Culture” Prepare to be shocked... :) Quality of Perl work in Opera

23. We are the Perl Community! Aim for the highest quality Set documentation and coding guidelines in your team Respect them! No quick & dirty please We can make a difference...

24. More CPAN Munin realtime statistics Storage subsystem Opera-core foundation classes More “modern” Perl Migrate majority of systems to 5.10.x More Catalyst? More Moose? Future of Perl at Opera

26. Strive for high quality Write about Perl. Go, Ironman! Get your company (more) on CPAN Hire unexperienced young developers. Train them. Perl is never the problem. Call to action!
