• Any Javascript optimization benchmarks?

  - by int3

  I watched Nicholas Zakas' talk, Speed up your Javascript, with some interest. I liked how he benchmarked the various performance improvements created by various optimization techniques, e.g. reducing calls to deeply nested objects, changing loops to count down instead of up, etc. I would like to run these benchmarks myself though, to see exactly how our current browsers are faring. I guess it wouldn't be too difficult to cook up some timed loops, but I'd like to know if there are any existing implementations out there.

• Would I want to throw an exception or an error in this PHP script?

  - by Tower

  Hi, I have a PHP script that runs database queries. Now, if a query fails, should I trigger an error or throw an exception? I noticed that if I do the latter, the script execution will stop after facing the exception. My code is as follows: if (!$this->connection[0]->query($this->query)) throw new Exception($this->connection[0]->error); What are the pros and cons of using exceptions for this kind of cases (failed queries)?

I'm looking for the similarity in the way things are done such as directory structures, conventions, etc, not a pros vs cons in speed, extra features, etc.
