For writing native GUIs for Erlang, [wxErlang][1] seems to be the most mature library today (also on [SourceForge][2]).

How do you justify Refactoring work to your penny-pinching boss? |

You've just written a pile of code to deliver some important feature under pressure. You've cut a few corners, you've mashed some code into some over-bloated classes with names like SerialIndirectionShutoffManager..
You tell your boss you're going to need a week to clean this stuff up.

Can I generate a Flex web and Air desktop app from the same source code? |
|apache-flex|desktop|air|adobe|flexbuilder| |
I'm new to Air. I've got an existing Flex 2 application which I'm considering bringing into Flexbuilder 3. My question is can I use the same base application (and source code) to make the Air version, or would I have to maintain to separate code trees: one for the Air version and one for the Flex/SWF version? |
Get contents just shows you the file's contents, while get revision replaces your version of the file.
To see the commands run by subclipse in the console view you should check the "Show SVN console automatically when command is run" option in tools/preferences/team/svn/console. |

String is not a primitive type, yet you normally want to use it with value semantics, ie like a value.
A value is something you can trust won't change behind your back.
If you write : String str = someExpr();
You don't want it to change unless YOU do something with str.

You need some decent symbols for the CLR. Set `_NT_SYMBOL_PATH` (in WinDBG, use File/Symbol File Path) so that it includes:

xtofl has the right answer for finding an array size. No macro or template should be necessary for finding the size of a struct, since sizeof() should do nicely.

UI design alternatives with Groovy/JRuby/Jython or other JVM languages ? |

For a developer in the Java eco-system, there is a handful of choices when it comes to UI design. The best known are:

You can get the by joining on the [row number](http://www.databasejournal.com/features/mssql/article.php/3572301). This is possible because since it's an identity, it will just increment as you add items, which will be in the order that you are selecting them. |

Thanks for the tip, you're right - ParseTree seems to be the only code out there with any manipulation of the AST going on, except that it's actually written in RubyInline so its a strange mixture between Ruby and C code. Very interesting reading though.

Well you could add a:

Yes memory usage can get real high and you might run into problems with your JVM, as the default setting is a bit to low.

You have (at least) 2 issues - the complexity of the environment (the server) and the complexity of the GUI.

It is impossible to elevate just one function or any other part of a single process, because the elevation level is a per-process attribute.
