Unity3d code clip : auto height lable and mouse touchable scrolling

var wasScrolling : boolean = false;
var scrollPosition : Vector2;

a temporary solution for PEAR Install with PHP5.3

I met a Bug of PHP(still doesn't fixed yet) about halt_compiler function which caused installing PEAR fail.

php go-pear.phar

This command doesn't work in PHP5.3

To fix(for the time being) it, use this command:

php -ddetect_unicode=0 go-pear.phar

Project "kana50" has created

I've been learning iPhone developing recently.
Finally I created a iPhone App and submitted it to to App store(still waiting to review).

And I decide make this iPhone App project Opensource:

How to fix PROCEDURE can't return a result set in the given context

CLIENT_MULTI_RESULTS enables the client program to process multiple results. This option must be enabled if you execute CALL statements for stored procedures that produce result sets. Otherwise, such procedures result in an error Error 1312 (0A000): PROCEDURE proc_name can't return a result set in the given context.

Using Beyond compare3 as Git diff tool under Cygwin

在Cygwin下使用Beyond compare3(BC3)作用Git的diff工具
分两步走~


step 1.
create new .sh file as Git's diff warpper.

#!/bin/sh
/cygdrive/c/Program\ Files\ \(x86\)/Beyond\ Compare\ 3/BCompare.exe "d:/programs/cygwin$2" "$5"

** please notice here, you need specially make a full path of $2, since BC3 will not find your tmp file under Cygwin path. **
** 注意这里的两个路径，第二个是本地文件，因为是相对路径，BC3可以找到，但第一个是绝对路径指向/tmp/xxx，所以我们要特别指定在windows下的真实路径，而不是cygwin的路径，所以我加上了d:/programs/cygwin。

step 2.
Add this line to .bashrc and run it to configure your Git gloabl variable.

git config --global diff.external /home/z33/git-diff-wrapper.sh

Now you can try git diff whatever your file.
