gwt compile speed

Hi,

Wondered if there is a solution for gwt permutation compile time, some way to speed it up, because 12 permutation compilation takes time, So there is one,
by adding the following option inside the compiler arguments:
"-localWorkers 2"

The "2" is the number of cores you got on the compiling computer and can be changed.

insert ampersand in oracle table

Hi,

This solution will work everywhere, no matter if you are using TOAD,sql plus, pl sql developer.

let's say we want to insert this "hello&world" inside a table that includes key's and values.
And our key, let's say is "title"

For example :

insert into table_name (keys,values) values ('title','hello'||chr(38)||'world');

That's the whole story.

Generate random passwords

Hi,

Here is a simple way with no effort to create random passwords like with the characters you want.

You will need this member:
 private static final String charset = "aAbBcCdD$#eEf!=m2MnN3oOp4P8VwWx9XyY0zZ";

And this method:
public String getPasswordString(int length) {
        Random randomSeed = new Random(System.currentTimeMillis());
        StringBuilder result= new StringBuilder();
        for (int i = 0; i < length; i++) {
            int pos = randomSeed .nextInt(charset.length());
            result.append(charset.charAt(pos));
        }
        return result.toString();
    }

Of course there is another way by using the  UUID object:
UUID.randomUUID().toString();

Or maybe using an external third party library.

Uncaught exception: java.lang.OutOfMemoryError: PermGen space

Hi,

Cause:
Memory leak or imperfect memory management of one of your modules.

Solutions:
1) Restart what you have done all over, if it was a server for example. This may happen when one of your    modules failed to be removed from memory.


2) Increasing your heap memory buy running with -Xmx512M


I recommend this books which relates to this issue:
