  • What is the best way to go about obfuscating Java code? [closed]

    - by Waltzy
    Possible Duplicate: Best Java obfuscator ? Well, I'm planning on releasing a Jar into the world but would prefer if the code was not readably available to anyone with a Java Decompiler as I want to control access to the program with usernames / auth codes etc. After some Googling I haven't found any software to do this for me, so I was wondering what steps to take from here; if anyone can point me at any software or information on methodologies of obfuscation I would be grateful. Cheers again Stack Overflow.

  • How to keep your self up to date? [closed]

    - by nimo
    Possible Duplicate: Staying Relevant As a Programmer As you all know in our line of work it is important to keep your self up to date with all of the technical progress that is being made out there. As a developer you have to be quick to grasp new programming languages and programming concepts as well as completely new technologies. I read about a guy who got fired at 50 years of age with tons of experience in some ancient technology and he now couldn't get a job anywhere because his experience wasn't in OOP or some other more modern concept. I don't what to end up in that situation. How do you keep your self up to date? How do you train your self and make sure that you keep your self at the forefront?

  • Should I Teach My Son Programming? What approaches should I take? [closed]

    - by DaveDev
    I was wondering if it's a good idea to teach object oriented programming to my son? I was never really good at math as a kid, but I think since I've started programming it's given me a greater ability to understand math by being better able to visualise relationships between abstract models. I thought it might give him a better advantage in learning & applying logical & mathematical concepts throughout his life if he was able to take advantage of the tools available to programmers. what would be the best programming fields, techniques and/or concepts? What approach should I take? what concepts should I avoid? what fields of mathematics would he find this benfits him most? He's only 2 now so it wouldn't be for another few years before I do this, (and even at that, only from a very high level point of view). I thought I'd put it to the programming community and see what you guys thought? Possible Duplicate: What are some recommended programming resources for pre-teens?

  • Are there actually lag times to remove an email address from "the system"? [closed]

    - by Alex Gosselin
    For example, you send an unsubscribe message to a legitimate company or a spam, they reply that they will remove you and it may take up to 72 hours to take effect. I find it hard to believe anything that simple could take more than 3/4 of a second to take effect system wide. Another example would be when you call the visa activation line, there is a "delay" of several minutes while they try to sell you some kind of insurance. Usually just as you get the point across that you don't want it they will tell you your card has been activated and let you go. Are these delays real?

  • Create proxy to Java app so it can work on the iPhone? [closed]

    - by Kovu
    okay guys, these are the facts: I have a java chat. I can NOT have any develop-revelant information. So this all is static. It's not my chat. So fact 2: IPad does not have Java and it will not have it in future. So now, the very hard task: bring this both together. My idea: Develope a proxy server for this. 1) The data from the IPad will send to a server. 2) the server recieve data and call the JRE and the complete chat-client 3) The server gets the "chat" himself and send it back to the Ipad Is that and possible idea or bad? Did I oversee something? Anyone have a idea where to start?

  • Why is i-- faster than i++ in loops? [closed]

    - by Afshin Mehrabani
    Possible Duplicate: JavaScript - Are loops really faster in reverse…? I don't know if this question is valid in other languages or not, but I'm asking this specifically for JavaScript. I see in some articles and questions that the fastest loop in JavaScript is something like: for(var i = array.length; i--; ) Also in Sublime Text 2, when you try to write a loop, it suggests: for (var i = Things.length - 1; i >= 0; i--) { Things[i] }; I want to know, why is i-- faster than i++ in loops?
