• Doing a float division without installing additional gems?

  - by Geo

  Let's say I have these two floats: a = 50.0 b = 1048576.0 c = a/b By printing c, I get this: 4.76837158203125e-005 Doing the division with calc.exe gives me the result 0.0000476837158203125 . Is there any way of achieving the same thing with Ruby without installing any additional gem?

• Excel VBA File not Found

  - by Brett

  During development of some Excel vba code about every other iteration where I go in and add some code then save the file, the next time I open the thing (it is automatically set to run the code on open) I get a spurious "File not Found" error. To fix it I copy all the code- modules and classes plus the startup code, to a fresh blank excel file save it and it runs fine. This happens in both Excel 2003 and 2007. What is happening here?

• std::set<T>::erase(key). What if key isn't there?

  - by Armen Tsirunyan

  if I erase an element from an std::set and pass the key, not the iterator, and the key isn't in the set right now, will an exception be thrown? The thing is every second sentence in the MSDN documentation says: "this does blah blah, but it doesn't conform to the standard". So I need to know the standard behaviour. I just couldn't find it in the standard. Redirecting to the relevant clause will do as well. Thanks.

• why copy and paste codes is dangerous

  - by Yigang Wu

  sometimes, my boss will complain us why we need so long time to implement a feature, actually, the feature has been implemented in other AP before, you just need to copy and paste codes from there. The cost should be low. It's really a hard question, because copy and paste codes is not a easy thing from my point. Do you have any good reason to explain your boss who doesn't know technology?

• How do I change the size of the menus in Visual Studio 2008?

  - by barriovolvo

  Hi all. This is the weirdest thing: For some reason, when I'm running VS 2008 in XP, and I use the 'Advanced Appearance settings' control panel to change the Size of menu items in all applications, Visual Studio 2008 is unaffected by the change. (That's Control Panel - Display - Appearance tab - Advanced - select 'Menu' from the item drop-down, and change the Font size) Anyone else noticed this? Is anyone aware of a fix? Thanks in advance!

• how to make sub-muens line up below their parents in horizontal navbars?

  - by Joel

  Hi folks. I'm just putting together a simple nav bar using something similar to this tutorial: http://www.cssnewbie.com/horizontal-dropdown-menus/ The thing is, that I'd like to have the children lists first item to line up directly below the parent. Right now, they just go wherever I float them. Is there a way to do this without absolute positioning? I'd like to achieve something similar to what these guys have in their top nav bar: http://michaelfranti.com/

• Does "opening a file" mean loading it completely into memory?

  - by mystify

  There's an AudioFileOpenURL function which opens an file. With AudioFileReadPackets that file is accessed to read packets. But one thing that stucks in my brain is: Does AudioFileOpenURL actually load the whole monster into memory? Or is that a lightweight operation? So is it possible to read data from a file, only a specific portion, without having the whole terabytes of stuff in memory?

• Evil merges in git - where do they come from?

  - by Benjol

  I've read this question and the answers, but what isn't clear to me is WHO creates the "changes that do not appear in any parent". Is it the git merge algorithm screwing up? Or is it because the user has to manually adjust the conflicts to get the thing to build, introducing new code which wasn't in either parent?
