Ophcrack Says Your Password Is Insecure 249

javipas writes "An insightful article at Jeff Atwood's Coding Horror reveals the power inside Ophcrack, an Open Source program that is capable of discovering virtually any password in Windows operating systems. The article explains how passwords get stored on Windows using hash functions, and how Ophcrack can generate immense tables of words and letter combinations that are compared to the password we want to obtain. The program is available in Windows, Mac OS and Linux, but be careful: the generated tables that Ophcrack uses are really big, and you should allow up to 15 Gbytes to store these tables."

I've always been interested in astronomy in general, and I was thinking that putting my dark skies to use by picking up decent telescope and learning a bit about the skies over my head. I have been doing a decent amount of web research, but I thought that the Slashdot community would be the perfect place to get opinions on entry level equipment, websites, and books.

The overall budget for this project is going to be around $1,000, and observations will be made from the back of my home primarily. I am particularly interested in the subject of astrophotography, but I understand that may be outside the scope of the initial budget. I would welcome any and all of your comments and suggestions for getting started in this fascinating hobby.

PS — I've already signed up for my local astronomy clubs next monthly meeting."
