  • Practical way to implement prevention of IP Spoofing

    - by user1369975
    I am an undergraduate Computer Science student and was hoping to gain some knowledge of ways to help prevent IP spoofing but all the resources I have tried out elaborate this concept in a theoretical way. I want to try out my hands at one of the techniques like: http://en.wikipedia.org/wiki/Port_knocking http://en.wikipedia.org/wiki/SYN_cookies How do I simulate this whole situation in my own system were I myself am the attacker and I myself have to defend it? And once I have gained an understanding of it, then how do I start translating that into programming terms?

    - by ErnstvdS
    I have one Dropbox (I suppose) shared between my business account / PC and my wife's account / PC running Windows XP and a laptop with Windows 7. I created a folder and shared this one with both (or three) accounts. I created an underlying folder (no need to share, says the help) but it is not visible on the other PCs, so I've shared it to both accounts. Is this sharing necessary for every simple new folder?

  • Blurred image recovery?

    - by m0s
    I have pictures of handwritten text and some of them are blurred, because the camera was shaky. If someone could point out any techniques that I can use to bring it to readable quality would be great. It is really a closeup, and I'm pretty sure it is doable. If you can recommend a specialized software or you know some techniques in photo-shop or any other software that would help please comment.
