Wikis in Plain English

We recently announced the availability of new wiki software for the Thayer School community. This web based software allows Thayer groups to collaborate and share information in new ways.

It can take some time to wrap your head around how wikis work, so some folks put together a short entertaining video that explains the basics. Take a look, and if you’d like us to set up a wiki for you, please go here for more information.

Backup Program Chosen: AMANDA

After performance and feature testing AMANDA and Bacula, we’ve decided to go with AMANDA. The speed that AMANDA was able to backup data over the network was nearly twice that of Bacula (80 MB/s compared to 40 MB/s), and AMANDA was slightly faster pushing data to tape (77 MB/s compared to 63 MB/s). The speed advantages that AMANDA showed within our topology were significant enough to warrant it as our backup program of choice. That being said, within other topologies and with different needs, I [snip...]

The Dog Ate My Computer

It’s a good thing that fancy warranty covers accidental damage.

But in the meantime your final presentation is scheduled in three days, you haven’t even finished the bibliography, and the depot says it’ll be at least a week to replace the chewed up power supply.

Yes, the rumors are true. Thayer Computing Services loans laptops.

We’ve got a pool of mostly Dell and a few Mac laptops [snip...]

AMANDA and Bacula: which backup program to choose?

An important part of any enterprise level storage system is the backup system. For our new inexpensive storage system, we want to find a piece of backup software that is both inexpensive (preferably free) as well as functional. My search for such a program has led to two main candidates: AMANDA and Bacula. I’ll start with AMANDA as that is where my testing began.

AMANDA approaches backups by using native programs such as postfix, tar, dump, xfsdump, etc within a client/server relationship. The [snip...]

How to Find Out if the Internet is Broken

Well, ok. Chances are the whole internet isn’t really going to break, unless another fire breaks out underneath a Boston subway station.

But, much as we try to avoid it, sometimes a small piece of our own corner of the internet here at Dartmouth goes down. And, naturally, when that happens you call us, wondering why you haven’t received any email in the past half hour. Or how come you aren’t able to open your hosted database.

But did you ever wonder how we know? [snip...]
