Teehee Teehee. No luck required.

It does however take a wee bit of skill and competence.

Actually, for exacting work, the source is a liability.

The source tends to make assorted bugs vanish.

Presumably you speak from your own experience and your own powerlessness.

If a programmer is competent, the programmer does not need the source and

the programmer does not even need to know the language. Assorted malware is

done without having the source. Very well it seems.

To EASILY change something, the source is needed.

Acutally, the entire build environment is needed.

Just having the source is easily less modifyable than having an operable

binary.
You're way out of your league here, sonny boy.
