The Project Euler Sprint Hack Nights

Project Euler Sprint Hack Nights are beginner friendly events where you can work on your own projects or engage in a friendly competition called the Project Euler Sprint.

The Project Euler Sprint is a friendly competition involving solving Project Euler ([http://projecteuler.net][projecteuler]) problems for points. Project Euler is a series of increasingly difficult computational math problems that must be solved with code (generally speaking - we've had some impressive solutions in pen and paper as well as on an Excel spreadsheet).

Each problem is harder than the last, so each problem is worth its problem number in points. Problem #1 is easy, so it's worth 1 point, while problem #50 is much harder, but worth 50 points. You can form teams of 4 people and solutions can be in any language as long as it's coded there. More detailed rules below.

Lancet. 2004 Sep 11-17;364(9438):963-9. MMR vaccination and pervasive developmental disorders: a case-control study. PMID 15364187
294 cases and 4469 controls were included. 1010 cases (78.1%) had MMR vaccination recorded before diagnosis, compared with 3671 controls (82.1%) before the age at which their matched case was diagnosed. After adjustment for age at joining the database, the odds ratio for association between MMR and pervasive developmental disorder was 0.86 (95% CI 0.68-1.09). Our findings suggest that MMR vaccination is not associated with an increased risk of pervasive developmental disorders.
Odds ratio below 1 suggests decreased, not increased, risk of autism with vaccine. CI crosses 1 so the effect of vaccine preventing autism is non-significant.
