    Re: What if there was a NEW vb6

    Learn a newer and better designed language.

    If your upset because technology changes, you're in the wrong field.

    You can manage the filesystem from most programming languages. Just read up on file processing.

    But to answer your question, most will be written in C. Server programming is quite tedious because...

    Re: What Boards have you used?

    I've done some bare metal programming on the raspberry pi in ARM. IE: no OS.

    But that's about it.

    Re: Possible? Or am I crazy?

    You can do a part of this with a raspberry pi. You would also need a breadboard and some external stuff, but it's doable.

    ugh.. you just reminded me of my first project in Computer Arch.. making...

    I can only blame myself since I made the post without proof reading or checking the formula. The main point to the topic was that mathematical identities are useful for speeding up certain...

    Any language or library can become obsolete. Mainframe coding for example has fell by the wayside even though it was huge at one time; however, there is a lot of mainframe code still in existence and...

    Economists are experts on the topic. I'll defer to them.
  10. Re: Using a mathematical identity to speed up certain calculations.

    I don't think one could tell much about comparing times like these. Processes are frequently swapped in and out by the operating system; as a result, one can't tell by looking at the system time how...
  11. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    Why do you keep insisting that computer security is some kind of technician job?

    Is that why MIT rolls out computer security to first year grad students?

  14. Re: Using a mathematical identity to speed up certain calculations.

    And it is easily solved by the Gauss identity. And it's rather straight forwards. After all, you implemented the method in one of your posts.

  15. Re: Using a mathematical identity to speed up certain calculations.

    A power set algorithm is what is needed. There have been many different power set algorithms made over the years, and one can find one of his or her liking with a quick google search.

    A company that delegates computer security to PC technicians simply doesn't have computer security. PC Technicians do not have the qualifications of computer security professionals; instead, PC...
  17. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    Uhh.. you obviously don't know what your talking about.

    Do you even know the background you need to do security as a profession? Obviously, this is a new world for you.
  18. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    Since when is security experts aka white hats known as "blue collar"? People who sign their paychecks would beg to differ. In addition, security is not the same thing as system administration.

  19. Re: Is the IRS story about the harddrive crash plausible to you?

    America's high inequality is an economic fact. In addition, the system is not designed to make everything equal as the high inequality is a counter for such an argument.

  20. Re: Is the IRS story about the harddrive crash plausible to you?

  22. Re: Using a mathematical identity to speed up certain calculations.

    You have to take a power set of it. Use the single elements in the formula, the rest of the elements are used for intersections.

    Example: The power set of <1, 2, 3>

    <<1>, <2>, <3>, <1,2>,...
  23. Re: Using a mathematical identity to speed up certain calculations.

    The topic already explained when and where this kind of method is useful. It works when you need to sum up a set of numbers. In addition, it teaches algorithms.

  28. [Computer Security] Defensive programming for web applications.

    The first rule of programming is to never ever trust the user. In fact, one should make the worse case assumption about users. In computer security, we call this assumption defensive programming....
  29. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    Right, .net programmers don't have to worry about memory allocation issues. So memory leaks and buffer overflows aren't their concern; however, everything else in security is a concern.
  30. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    For visual basic programmers, logical problems, authentication problems, and failure to handle user input correctly will be the largest source of security problems. For example, visual basic programs...
  31. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    Computer security is a programming concern. The exploit is caused by bad programming. For example, the above exploit worked because some programmer at Microsoft didn't control a buffer. The program...

  33. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    Yes and no. The security team at target dropped the ball in a big way. They were getting fire-eye warnings that their network was compromised; however, they ignored those warnings. So they didn't...
  34. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    I think security people need to promote security practices in forums like these because a lot of people here end up working in IT or land some programming jobs. And people here really need to...
  35. Re: [Computer Security] Demonstration of the aurora hack: how hacking works.

    In the future, I'll write on detection. I'll set up the penetration stuff to generate data (it's complicated anyway), then show people what the data looks like in something like splunk.
