I was the emcee in GeekcampSG 2019. I asked a total of 66 trivia questions in the effort and excuse to give out leftover plushies from the previous Geekcamp 2018+.

These questions spanned topics from Singapore, Science, Fiction, Computing, Retro-tech and miscellaneous general knowledge. Topics I feel would appeal to a stereotypical geek audience and someone like myself. Try to see how many you can answer.

Trust me, the collating of these questions and researching their answers took over a period of several years to prepare for such a day. It was fun to finally see the fruits of my labour. Coming up with questions that can’t be too easy that everyone knows the answer or too hard that no one knows is difficult. Fortunately for me, at least 3/4 of the questions could be answered correctly by at least one person.

When you watch Western law shows, you will notice that they have jury where a panel of ordinary people will decide the verdict instead of the judge. Singapore used to have a jury system up to 1969. Why was this abolished?

Singapore’s currency has constant parity to which other currency?

Brunei. Currency Interchangeability Agreement in 1967. Singapore, Malaysia and Brunei were the original parties in the agreement. Malaysia pulled out in 1973. This was partly due the to the events of 1971 where the US dollar was decoupled and no longer backed by gold. Google Nixon Shock and Bretton Woods for more info.

This economic indicator NODX is commonly used by Singapore economists but not so much in other countries. What is it and why is this the case?
