Broad Street Run 2010

I did better than last year! If we run next year, I’m going to shoot for under 2 hrs…it should be doable!

Project Euler Problem 10 Solution: Clojure

Problem description, from Project Euler Find the sum of all the primes below N. Solution Brute-forced it again, but it still runs in less than 30 seconds (at least on my MacBook Pro). This one was simple using the Sieve of Eratosthenes from problem 7. The sieve, collapsed because it’s the same as from problem […]

Project Euler Problem 9 Solution: Clojure

Problem description, from Project Euler There exists exactly one Pythagorean triplet for which a + b + c = N. (N is known.) Find the product abc. Solution This was a quick once since I just brute-forced it. I think there are some optimizations possible related to the idea that a^2 + b^2 < c^2. […]

Project Euler Problem 7 Solution: Clojure

Problem Description, from Project Euler What is the n-th prime number? Problem Solution This was simple to solve using the Sieve created for the solution to problem #3. To make the program variable, we start with finding all primes less than 1000. If that is not enough to solve the problem, we double this “maximum” […]

Sql Cross Apply

I found out about a feature in SQL Server 2005 I didn’t know about (having come from a SQL Server 2000 shop). Cross Apply! It’s for when you want to feed the value of a table row into a function and join on the results. This is different than a cross join, because you cannot […]

Project Euler Problem 4 Solution: Clojure

Problem Description, from Project Euler Find the largest palindrome made from the product of two 3-digit numbers Solution I couldn’t think of many optimizations for this problem, other than avoiding duplicates when calculating the products of numbers. That’s why I just brute-forced it. The only (barely) interesting thing I did here was to write a […]
