  1. Glad I could help. Most languages are fairly similar if you code cleanly. It's not that hard to learn another once you get the first language down. Some people get lazy with their code and obfuscate it quite a bit, and I could have written the same thing in a perl one liner program, but I specifically made it easy for you to read. Most developers work on a team, and it makes sense to write code in a way that others can understand by a simple glance at it. As long as you code cleanly, you should be able to move through languages with ease. Good luck with your programming.
  2. Sorry I thought the challenge was the number of items entered by the user, not the closest fibonacci number. That's an easy fix, it's a while loop instead of a for loop. #!/usr/bin/perl print "\nHow many numbers of the sequence would you like? "; chomp($n = <STDIN>); &fibonacci($n); sub fibonacci { $a = 0; $b = 1; $n = shift; while ($a <= $n){ printf "%d\n", $a; $sum = $a + $b; $a = $b; $b = $sum; } } You could use the previous code and do-while with two iterations in the do section. However, if you really want to play around and have fun with it, a recursive function could be fun with this. You could play with code similar to this.... sub fibonacci { $num = shift; $calc = 0; if ($num <= 1) $calc = $num; else $calc = fibonacci($num - 1) + fibonacci($num); return $calc; } Sorry about the shorthand, I didn't want to do your homework for you, but still help you. That's why I didn't give it to you in C. Shift just takes the first item off an array. If the array isn't listed, Perl assumes it is @_ and since that is what is passed to the subroutine, that's the passed variable.
  3. This should really go in the programming thread, but since it is a newbie question I'll help. PART 1. You are making it much more difficult than it needs to be. Here is the program in Perl. #!/usr/bin/perl print "\nHow many numbers of the sequence would you like? "; chomp($n = <STDIN>); &fibonacci($n); sub fibonacci { $a = 0; $b = 1; $n = shift; for ($i=0;$i<$n;$i++){ printf "%d\n", $a; $sum = $a + $b; $a = $b; $b = $sum; } } PART 2. To just have it run automatically with only the first two entries, you just hard code it. For example. &fibonacci(2);
  4. I came across this. Some cool decryption that will get your name out there. http://news.yahoo.com/s/yblog_thelookout/20110329/ts_yblog_thelookout/fbi-asks-public-for-help-breaking-encrypted-notes-tied-to-1999-murder
  5. I like this place. I don't want to see it go under. Yup Where do I sign up? DONE!!! ep0653 :: Intro to Black Box Testing Hosted by Heisenbug on 2011-02-02 I have a cool stirplate hack on there. Done. Yup Haven't done that yet, but will. Haven't done that yet, but will.
  6. This statement seems like a combination of arrogance and ignorance. It is something that a recent Computer Science graduate would say. The more we learn, the more that opens up, and the more we know we have so much more to learn. In fact, I don't know a single senior level computer scientist that believes they know everything about computers. It is only the ones that haven't delved deep enough into the machine that feel they know it all.
  7. I wouldn't get into the habit of using software just because it was installed on your computer. I would use the best available software available. Installation isn't that difficult. That said, Ubuntu going forward is not going to use OpenOffice due to the Oracle issues. It will be using LibreOffice in the next release (Ubuntu 11.04 on April 28, 2011), so if that is your operating system and you want to future proof your software I would still go with LibreOffice.
  8. LibraOffice forked off of OpenOffice. The question you should ask is why was this product was needed and created in the first place. It's because Oracle recently acquired OpenOffice. Oracle is not continuing support of the open source projects it took over from Sun in the spirit of open source. The open source community is not too happy with them. Oracle tends to control the code tightly, and prefer their own developers develop the code. Many people in open source are shunning Oracle and will refuse to work further on OpenOffice. It will probably continue to be freeware, but won't get a lot (if any) open source support, especially since Libra Office is out there now. Right now there isn't a lot different with them because the code fork just happened, but over time, LibraOffice will be developed on and embraced by the Open Source community. OpenOffice will not. Can you tell this was written by an open source developer??? Ha, oh well. Honestly all bantering aside, without community support and involvement, features will be added that are unimportant to the end user and that cause bloat and important features that end users really need may not always be added. Libra Office will be a better product in general, both physically and ethically. EDIT: FORGOT TO REPLY TO CYB3R_THR34T http://www.thefreecountry.com/compilers/basic.shtml
  9. LibreOffice is the open source fork off of OpenOffice. I would suggest LibreOffice. Although I would suggest OpenOffice over Microsoft, even on Windows. They will open office documents, and save as them so you should be fine. The display on the "powerpoint" alternative slides are sometimes a little off, but can be fixed easily. Other than that a great alternative. I always though Microsoft Works was the biggest oxymoron in technology.
  10. Not a bad board. Anything that promotes hacking and community is a plus in my book. It looks like they both use IPBoard and the favicon is not either binrev's or leethacker's, but belongs to invisionpower, which created the forum software they both use. http://www.invisionpower.com/products/board/
  11. Ha, now that's social engineering if I ever saw it. You may be a 400lb man in his mother's basement, but I'll give you the benefit of the doubt and assume this is true. If you are really honestly interested in security I would start with the Black Hat presentations. There are a few on rootkits.

  12. After reading your comment #4 I also got really annoyed. I agree with Berzerk on this. Correct me if I am wrong, but it seems you don't know the difference between petty theft and hacking. Here is what I consider the difference: HACKING - Taking a computer, and figuring out a way to bypass the password. Disseminating the contents of the drive to find the owner's name, address, and pictures of them to identify them. Being nice and installing programs to help them find their PC if they lose it again. VNC - (to view the system) An SSH server - (to help retrieve their files) An IP beacon - (To say when the PC is online and what the IP address is) [*]Returning the laptop to the owner. [*]Occasionally checking in on the PC to make sure the system is ok, and they didn't lose it again. (What a good citizen!!!) PETTY THEFT - Not using google to find a simple kiddie script. Being an idiot and telling everyone you are committing a crime.
  13. Yes, you can wipe the drive and install a fresh copy of Windows, or Linux (free); however, you will lose all of your data. You can recover that data by booting from a Linux CD. Ubuntu Live CD or knoppix will work well for this. Once you boot up, you will be able to access the NTFS formatted hard drive and copy the files you need to a USB drive. If you bought the PC used, I wouldn't use the same OEM (Microsoft Product ID) or the same MAC Address. You don't know if the guy before you was some kiddie porn collector or something. I would suggest removing the partitions, formatting the drive, encrypting the entire drive, and installing a fresh Operating System after that. If it was always your PC, and you just forgot your 35 digit password with lowercase, uppercase, numbers and special characters. I haven't used it, but I hear Kon-Boot works well to strip the passwords.
  14. If only a few people you know are going to be using this, then create a certificate and require the browser to have it. You might want to protect yourself from SQL injections. Striping out semi-colons is important. Also less than, greater than, equals signs, etc... And if it doesn't need to be in there, INSERT, DELETE, DROP, UPDATE, etc. (No one should have a First Name, Age, Etc of DROP or UPDATE) Use dropdown menus, check-boxes, radio buttons, etc whenever possible. The option they pick better damn well be one of the choices you gave them. If it isn't then I would just log their IP and exit out of the script.
  15. I think that it's interesting when people say, "I use Mac for the hardware", or "I just use Windows because my Dell came with it." Isn't this a hacker forum? I have switched operating system many, many, many times. I find operating systems fascinating, and have delved into the depths of many. Even as far as contributing code to distributions. I use a few different ones, but I have my favorites. I don't think it matters what came on your box, if people like Mac then they can install a Hackintosh, or if they like Windows they can install that too. I don't think people should keep a closed mindset on operating systems. They should use what they like best. If they like what OS came on the hardware in the first place, then awesome...use that; however, most just use it because they can't fathom that an operating system can be changed. Hardware != Software
