• Websites that archive cross-browser css/js bugs?

  - by meder

  I'm about to develop my own browser inconsistency/bug compendium site but I'm wondering if I really need to - can we get a wiki of sites that do this already? I'm aware of a lot of them but I hope I'm not missing out on some major ones. I wanted mine to be more intuitive and social-like for most people, powered by tags and screenshots and test-case pages.

• Python: if key in dict vs. try/except

  - by LeeMobile

  I have a question about idioms and readability, and there seems to be a clash of Python philosophies for this particular case: I want to build dictionary A from dictionary B. If a specific key does not exist in B, then do nothing and continue on. Which way is better? try: A["blah"] = B["blah"] except KeyError: pass or if "blah" in B: A["blah"] = B["blah"] "Do and ask for forgiveness" vs. "simplicity and explicitness". Which is better and why?

• How to vertically center content with variable height within a div?

  - by jessegavin

  What is the best way to vertically center the content of a div when the height of the content is variable. In my particular case, the height of the container div is fixed, but it would be great if there were a solution that would work in cases where the container has a variable height as well. Also, I would love a solution with no, or very little use of CSS hacks and/or non-semantic markup.

• No IO exception reported for socket operation when the interface is removed

  - by user352536

  The wifi network is connected, the application setup a socket connection and exchange data with the remote server. But when turn off the wifi, the inteface is removed, while socket operation read/write on this socket is still like normal, no any IO exception reported. The application has to do some extra checking to avoid waiting for the data forever. Is this the normal case for Android design? Is there any plan to fix it?

• initialize a const array in a class initializer in C++

  - by Nathan Fellman

  I have the following class in C++: class a { const int b[2]; // other stuff follows // and here's the constructor a(void); } The question is, how do I initialize b in the initialization list, given that I can't initialize it inside the body of the function of the constructor, because b is const? This doesn't work: a::a(void) : b([2,3]) { // other initialization stuff } Edit: The case in point is when I can have different values for b for different instances, but the values are known to be constant for the lifetime of the instance.
