We use a coding test as a part of the interview process for new developers and it works quite nicely. Note it is just one part of the process, though it can help sway a decision wh…

Until the source site changes the URL, or the URL arguments, or the page structure, or the doctype, or the CSS selectors, or the element ids, or whatever it is you key on to ferret…

The submission was meant to be humorous, sorry to disappoint. No matter how you slice it parsing HTML from a 3rd party site is a major hack, though this does however work nicely (i…

I have been working on this question for a long time and I think most people have been fooled into believing an incorrect answer. My research indicates that it's actually 41.

Insofar as Nanex is concerned remember they are attempting to sell you a product, so be aware of their motivations before swallowing any unsubstantiated assumptions. With that said…
