• Do you have any tips for commenting code?

  - by Rob Wells

  G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code.co My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say".

• Is there a limit for the total variables size on the stack?

  - by Jay

  While coding should we consider some limit on the total size of variables created on the stack? If yes, on what basis should we decide it? Is it dependent on OS, Memory Availability etc? Are there any compiler options which can check this? Any pointers in the direction will also be helpful.

I saw some people put all modules in one view stack ,and so the application interface is only load once, but when the application get larger, the whole compiled swf would be very big. If we put swfs in different pages, we pass request parameters through HTTP request, we lost the benefits from flex RPC services, slow loading, and we can't see any superior comparing to php,asp,jsp... what's the best practice to organize front end architecture?

• If it is possible to auto-format code before and after a source control commit, checkout, diff, etc.

  - by dennisjtaylor

  If it is possible to auto-format code before and after a source control commit, checkout, diff, etc. does a company really need a standard code style? It feels like standard coding style debates that have been raging since programming began like "put the bracket on the following line" or "properly indent your (" are no longer essential. I realize in languages where white space matters the diff will have to consider it but for languages where the style is a personal preference is there really a need to worry about it anymore?

• Why do you like Python?

  - by Arnav

  I have to make a presentation at work to convince everyone why they should try coding in Python. So, I thought of taking a poll here... What is it about Python (features, etc) over other languages that you love? The reason I usually give is that in Python you forget about the complexities and frills of programming languages and can just focus on producing code that works... What do you think?
