τεχνοσοφια

In spite of how irksome I find "oh hai i upgrayded!" posts, I'm about to be guilty of same.

I upgraded my Optiplex GX620 from Gutsy to Hardy yesterday afternoon and it seemed to go as smoothly as it did on my HP box at home.  All looked a-okay this morning until, upon returning from a meeting, my display was all funky and jerky and laggy.  The right edges of my windows were uniformly screwy — I would have to click about an inch to the left of whatever I wanted to click on — and the right and left edges of the screen caused visual trails when I dragged windows around.  (And this has nothing to do with my usual breakfast of bacon and psychedelics.)  This wasn't the first time I've run into problems with compiz/beryl and Ubuntu and so I was hopeful that things could be easily remedied.

I was still able to get around a bit and I found a Hardy installation guide that fixed me all up (I hope).

I should probably note that the Optiplex in question has an ATI Radeon X600 series video card.

Pining for the visual trails,

P.S. Ubuntu, I still ♥ you.

Guess who is finally on Twitter?

In spite of some open questions, I've been making some progress on my Jython-based transport tool. Right now it's pretty dumb and simple: it copies files to and fro via scp.

Being a newb at both Java and Jython made finding the right libraries a bit of a challenge, and so I'm posting some code here for folks in the same boat. It's not particularly pretty due to 1) wanting to get something working very quickly, and 2) weird errors when I try to make things prettier (such as getting rid of the hard-coded bits), but I'll resolve these soon.

It's hard to believe but I've been at the new job for six months already, a full half-year come the 29th. Some days it seems like I've been here forever; others like I'm still a rank newb. I haven't written terribly much about what I've been up to (but I assure you I've been busy). Let me rectify that.

The Transfer Problem

Two of the projects I've been working on relate to a fairly general problem that we like to call "transfer," which revolves around, well, transferring files to and fro. Sounds simple. Is simple. That is, until you start thinking about preservation and accounting for a highly heterogeneous network with idiosyncratic nodes, esoteric storage software, and differential firewall rules. And that's where it gets interesting (and problematic). Continue reading…
