Running a Perl Quiz Nightby eyepopslikeamosquito (Chancellor)
|on Apr 25, 2007 at 13:02 UTC||Need Help??|
Last month Sydney.pm ran its first ever Perl quiz night. It was a lot of fun so I thought I'd share the experience here.
In addition to offering some tips on running your own Perl Monger quiz night, I present below the sets of questions used, along with the answers from each team, to allow you to have a go at the quiz yourself and see if you can beat any of the teams.
We'll be running more quiz nights in the future, so your feedback, especially suggestions on how to run a quiz night and your ideas for quiz questions, are most welcome.
A common problem we've had at our Perl Monger meetings is "breaking the ice", getting people talking and mixing, especially with shy new members. So I was hopeful that a quiz night would help here and I'm delighted to report that it did. We had a couple of newbies along and putting them in teams with some oldbies had everyone mixing, talking and having a lot of fun together discussing the questions. Tip No. 1: When choosing teams, try to split up friends/workmates and make teams of people with varying levels of Perl experience.
Of course, the pizza and beer helped a great deal, generously donated by adamk in response to Chris Williams, aka bingos, winning the The Sydney.pm Less-Than-A-Metre-Of-Beer Challenge, where adamk clarified an important prize condition: "I will force Sydney.pm to toast your name for every beer they open, all night". I can confirm that adamk did indeed enforce this condition and that every single beer opened on the night was accompanied by a loud and raucous "Cheers, Chris Williams!", even a hip-hip-hooray at one point ... which also helped to break the ice. Tip No. 2: Provide free food and refreshments (preferably beer).
I prepared seven sets of ten questions and kept a running score of each team on the whiteboard, with a small prize awarded to the winner of each round and a bigger prize for the overall winner. This took about two hours (about right for us) and proved exciting, with two teams tied for the lead going into the final round. Tip No. 3: Award a small prize after each round. Make sure everyone gets a prize.
After each round, I got each team to swap their answers with another team for marking. Then I wrote the round's answers on the whiteboard. This worked well, sparing me the bother of marking each team's questions -- and generating some teasing and banter between teams when easy questions were answered incorrectly. Tip No. 4: Get other teams to do the marking. Keep a running leaderboard.
I chose a mix of about half Perl and half non-Perl questions. This turned out to be a good balance: plenty of Perl for the hard-core mongers, with non-Perl questions to make it attractive to non-Perl attendees (family, friends, etc.). Tip No. 5: Have a mix of about half Perl questions, half non-Perl questions.
In addition to the seven sets of ten questions, I prepared a short list of "table questions", harder questions that the team could mull over during the night, especially during the breaks between rounds. This set of questions stayed on the table all night. Tip No. 6: Provide a set of "table questions".
Now to the questions. Though I enjoyed writing most of these myself based on my own personal bias/knowledge/experience, I got some great ideas from grantm's Wellington.pm quiz night and adapted some of the questions from there. Though we started with a round of ten Sydney.pm-specific questions, some of them relentlessly teased certain Sydney.pm members (who shall remain nameless), and are of little interest to a general audience, so I won't present them here. Below are the other six rounds of the contest, along with the answers from each of the teams -- and the "table questions". If you want to have a go yourself, simply answer each set while resisting the temptation to peek ahead at the answers. Enjoy!

10. Who wrote the following?
The competent programmer is fully aware of the strictly limited size of his own skull; therefore he approaches the programming task in full humility, and among other things he avoids clever tricks like the plague. In the case of a well-known conversational programming language I have been told from various sides that as soon as a programming community is equipped with a terminal for it, a specific phenomenon occurs that even has a well-established name: it is called "the one-liners." It takes one of two different forms: one programmer places a one-line program on the desk of another and either he proudly tells what it does and adds the question, "Can you code this in less symbols?"---as if this were of any conceptual relevance!---or he just says, "Guess what it does!". From this observation we must conclude that this language as a tool is an open invitation for clever tricks; and while exactly this may be the explanation for some of its appeal, viz., to those who like to show how clever they are, I am sorry, but I must regard this as one of the most damning things that can be said about a programming language.

Acknowledgements: I'd like to thank stennie of Sydney.pm for helping to organize the quiz night and being so patient with me, grantm of Wellington.pm for giving us the idea of running a quiz night and for generously sharing his experience and questions and adamk for the free beer. Oh, and Cheers Chris Williams! :-)
Update 26 Apr: Fixed a couple of typos in the answers and where I misspelt Williams as Winters.
