Objective-c runtime fun -- A UIButton that takes a block as an action. The cool thing it does is it adds this action as an instance method at runtime.
#import <objc/runtime.h>
typedef void (^buttonAction)(UIButton *sender);
@implementation UIButton (BlockAction)
+ (UIButton *) buttonWithType:(UIButtonType)type andAction:(buttonAction)action forControlEvents:(UIControlEvents)controlEvents; {
UIButton * button = [UIButton buttonWithType:type];
// suppress undeclared selector warning or else '@selector(action:)' will complain.

Send iMessage from the commandline
#!/bin/sh
if [ "$#" -eq 1 ]; then stdinmsg=$(cat); fi
exec <"$0" || exit; read v; read v; read v; exec /usr/bin/osascript - "$@" "$stdinmsg"; exit
-- another way of waiting until an app is running
on waitUntilRunning(appname, delaytime)
repeat until my appIsRunning(appname)
tell application "Messages" to close window 1
delay delaytime
end repeat
