>>Maybe I'm not part of the target audience for this article, but it seems to lack quite a bit of information.
I think for anyone with minimal assembly experience or a desire to learn this is pretty straight forward.
>>For example, you explain what op-codes are, but then only cover one of them.
He gives you a link to the list of all of the op codes... Did you read it?
>>I think at least a basic overview of common op-codes and how they work together would have been great
Maybe this is going to be in a follow up article. But after explaining the concept, giving you toy example and giving you the opcode list, with the provided hexdump you should be able to start doing this yourself. Try it! Its fun.
>>Also, the "hacking" you demonstrate is simply replacing a string, which is certainly not Java-specific and rarely useful
Intro to concept examples are often toy examples....
