• What does `const` do when combined with `readonly`?

  - by Byron Sommardahl

  The difference between const and readonly is well covered. A const can't be changed and a read only can only be changed in a constructor. But, what happens when you combine the two: public readonly const string how_does_this_behave = "I don't know"; The compiler allows it. But I'm not sure how it behaves from this point on. Thoughts?

• Buildout: when to use buildout:eggs and when to install via zc.recipe.egg ?

  There seem to be more than one way to install eggs into a buildout. Way 1: [buildout] ... eggs = eggname othereggname ... Way 2: [buildout] ... parts = eggs [eggs] recipe = zc.recipe.egg eggs = eggname = othereggname Both ways work. ( variation on way 2 would be to install each requirement as a separate part. ) What is the difference between these 2 methods?

• Symbolizing plugins in Instruments' stack traces

  - by Huperniketes

  Instruments is able to properly symbolize my app's main bundle (as well as frameworks and libraries) in the stack trace of the extended detail view. However, symbols aren't resolved for plugins loaded during execution. Setting the build directory where the dSym files for the main and plugin bundles are located (as well as the app itself) in the "File Re-Symbolicate Document" menu item made no discernible difference in the stack trace. What must I do for Instruments to load symbols for the plugins?

• Word 2007 - Pasted Text Not Spellchecked??

  - by Albert

  My Word 2007 spell-check seems to work fine, except that when I paste in text from somewhere else, it won't detect any misspellings in that pasted text...no matter what I try. If it makes any difference, when I paste in text, the formatting is preserved (size color etc). Any ideas on what to try?

• Incorrect Coordinates From getLocationOnScreen/getLocationInWindow

  - by nimph

  A call to getLocationOnScreen() or getLocationInWindow() both give me a top/Y coordinate that is about ~30px (status/notifications bar's height) too far down. The left/X coordinate is dead on. As I hinted above, I believe the difference is because of the status/notification bar... I could be wrong. I think I can solve this if I can determine the size of the notification bar but, I'm having trouble doing just that. Any help would be greatly appreciated.

• Use case of Glass Pane vs. Layered Pane

  I've always been a little fuzzy on the difference between the glass pane and a layered pane. Is the glass pane essentially just "the very top layer of the root pane," or does it behave differently? When would you use a layered pane instead of the glass pane?

• Setup a https client in Java

  - by Albinoswordfish

  I'm very new to HTTPS/SSL so excuse my lack of knowledge. Right now I'm trying to setup a simple Java client in which it connects to a web server through HTTPS. I've seen some example code online but can't seem to really make sense of it. Also I was wondering if there is a difference between setting it up on a Windows machine compared to another type of OS. If anybody knows a good tutorial on this or can head me towards the right direction it would be appreciated.

• Cost of exception handlers in Python

  - by Thilo

  In another question, the accepted answer suggested replacing a (very cheap) if statement in Python code with a try/except block to improve performance. Coding style issues aside, and assuming that the exception is never triggered, how much difference does it make (performance-wise) to have an exception handler, versus not having one, versus having a compare-to-zero if-statement?
