Linq Aggregate Empty Sequence

By Josh Perry | Published: April 20, 2010
Linq is great for its compact expressions, and for its — usually efficient — lazy-evaluation. These two virtues seem to be spit upon by the Aggregate function. Say you want to aggregate a list of ints. var s = new int[] {1, 2, 3}; int sum = ints.Aggregate((a,b) => a + b); This works great [...]

By Josh Perry | Published: April 20, 2010
So, today(2010-04-13) it was announced that Opera Mini for the iPhone had been accepted by Apple and in deed it was revealed in the Appstore within a few hours.
