Could anybody suggest some name ideas for a program (UNIX command-line/cron job, not GUI) for progressively backing up/archiving files in a directory tree to archive volumes and sending them to some remote location (i.e., Amazon Glacier, or else a server reachable by ssh)?

In this game, you roll a number of six-sided dice to get a
total. The total is either the highest single die result, or the sum of any multiples rolled, whichever is higher.
For example: If I roll three dice and get a 3, 4, and 6, my total is 6. But if I roll a 4, 4, and 6, my total is 8, the sum of the two 4s.
What I want to find out is the mean, median, mode, and standard deviation of the possible totals given N dice. How might I create a simple script to compute this?

I'm looking for a forum where I can ask questions about networking, security, coding, operating systems, web design, etc. There are
many of these out there, but I'd like to find a
single community which covers all these topics more or less equally (so it isn't a Linux forum with a small section on BSD, or a coding forum with a small section on networking). I'd like it to be the sort of forum where users stay around for several years as they learn and contribute at different levels, with high literacy and education-to-spam levels. Could I have your recommendations please?

ls command: the output scrolls off the screen a lot of the time, so I find myself doing
ls | less. There's probably an easier way to get
ls to pause and wait at the end of every screenful of output. Could you tell me what it is? Sorry if this is a dumb question.

I'm a Windows systems administrator and power user and an enthusiastic user of Unix/Linux-based operating systems. I have hand edited make files and recompiled linux kernels manually. I know how to do administrative scripting and am a Microsoft products (SharePoint, if it matters) support professional/systems engineer in my job. I am certainly not the geekiest person I know but I'm in the top 5 percent.
I am switching to a Mac Mini (Lion Server, specs maxed toward storage) after decades of using Windows laptops/desktops and some Linux machines. I'm prepared for the lack of physical mobility, but I don't feel prepared for not being a power user. What methods/resources would you suggest I could use to get up to speed with being a Mac Mini and OSX Lion power user?

I am trying to clone a Sun V440 server that is using the built-in raid (not disksuite). When I move the seed drive from the original server to the new server, the raidctl program complains that the drive is already part of another raid set (which it is), but I'd like to use it anyways as a seed for the new server. Any tips?

I'm curious as to what are the current "best practices" when it comes to centralized administration of a network of Unix (primarily Linux, but not necessarily so) machines? Essentially, what is the equivalent of Active Directory for a network with one or more Unix hosts? The immediate answer I come up with would be something like
OpenLDAP plus PAM but what I'm looking for is the suite of tools (GUI and CLI apps) for managing the directory, deploying software, centralizing sign-on and security, managing printers, etc.
In a perfect world, I would like to centralize administration of Windows, Unix, and OS X machines via a single directory service, though I imagine such a solution would be expensive and/or cumbersome if it even existed. Or is this something
Samba 4 will do?

I have a podcast that downloads as multiple segments over multiple days. Its format arrives as YYYYMMDD_showcode_segment.mp3; so, for example, one download might result in files as 20090323_goofa_01.mp3 through 20090323_goofa_21.mp3, and also
within the same download 20090324_goofa_01.mp3 through 20090324_goofa_21.mp3. What I'm looking for is a Unix script (shell, perl, what have you) that would look at a directory and look at what dates are represented there, and let me join all of the segments together by day. I can use mpgtx -j to do the actual joining; I'm looking for the code that would let the script determine what dates are in the directory and then get each day's segments united into a single MP3 for that day's show.
