Interview questions are artificial and not like real work
From 3 comments

Interviews test exam skills rather than real ability

Pricing level for the paid questions
From 1 comment
Love to get some thoughts from people on the pricing. Today the first 3 questions are free, and it's $5 for access to the other 11. How would people feel about $10? $20? What if…

Whether a Bloom filter beats a trie for visited links
From 1 comment
For the indexing the web question (what data structure should an under-resourced web-crawler use to keep track of visited links?) wouldn't a Bloom filter work better than a trie?

Good execution on a simple premise. Another terrific resource that I've pointed a lot of friends to is Project Euler -- a little heavy on the math but a lot of interesting…
