Hi, I am building an application where i need to have an admin interface from where the admin can assign permission for different methods (create, edit etc.) in controller based on roles . It should be similar to django administration, where we can assign permission on methods based on the role. How can i do the implementaton ? Can anybody give me some pointers on how to start ? Thanks and

Are there any open source efforts ( I haven't found any) that have a tftp server with a mysql backend? I'd like an incoming pxelinux request to give the tftp server the mac address, and then it performs a query to find out which configuration file it should get. Of course it would be great if some day tftp-hpa would integrate with libmysql.. Thanks, James James S. Martin, RHCE

Suharto, If you're interested in performance with subscripting, you might want to look at pqR (pqR-project.org). It has some substantial performance improvements for subscripting over R Core versions. This is especially true for the current development version of pqR (probably leading to a new release in about a month). You can look at a somewhat-stable snapshot of recent pqR development

Hello, Sometime ago min rsa key length was increased to 1024 bit and i have a little understanding problem with this. I hope somebody with some crypto-experience can enlighten me. To make that clear, that is not about allowing lower keys in general. Personally i would tend to use even longer keys(2048bit+). However Due nature of RSA-algorithm in case of 1024bit this might result in a key
