  • Circular increment: Which is "better"?

    - by Helper Method
    When you have a circular buffer represented as an array, and you need the index to wraparound (i.e., when you reach the highest possible index and increment it), is it "better" to: return (i++ == buffer.length) ? 0: i; Or return i++ % buffer.length; Has using the modulo operator any drawbacks? Is it less readable than the first solution?

  • Is there a way to close a Unix socket for only reading or writing?

    - by Sii
    Is there a way to only close "one end" of a TCP socket to cleanly indicate one side of a connection is done writing to the connection? (Just like you do with a pipe in every Unix pipe tutorial ever.) Or should I use some in-band solution like a sentinel value or some such? I only found shutdown() in the libc documentation and that doesn't seem like it does what I want.

  • How do I provide basic configuration for a Scala application?

    - by Dave
    I am working on a small GUI application written in Scala. There are a few settings that the user will set in the GUI and I want them to persist between program executions. Basically I want a scala.collections.mutable.Map that automatically persists to a file when modified. This seems like it must be a common problem, but I have been unable to find a lightweight solution. How is this problem typically solved?

  • Custom Visual Studio 2008 Designer

    - by Mick
    How do I create a custom Visual Studio 2008 UI designer for a C# file? For example, when you double click on a DataSet in the Solution Explorer, a UI screen appears that allows you to edit the DataSet, even though it is defined in XML/code (which you can right click and "View Code"). Usually this code is separated from user code in some way, either by region ("Windows Forms Designer Generated Code"), by codegen (".g.cs" for WPF XAML files), or some other means like partial classes.
