Johan Oskarsson has organized a meetup for folks interested in distributed structured data storage and is calling it NOSQL. The event, being held June 11th in San Fransisco, will have subject matter experts presenting on Hypertable, HBase, Voldemort, Dynomite, and Cassandra.
There were 100 slots available slots to attend and they all went in a matter of hours, so if this is the first you've heard of it, it's probably too late. Fortunately I got mine and thanks to the support of my employer I'll be there. I'm looking forward to it.
Getting the Epson Perfection 3940 scanner setup on Linux requires jumping through just enough hoops that even if you have managed it before, it's easy to forget when it comes time to do it again.
I put this here in the hopes that it will make things easier for someone, (and it's entirely likely that someone will be me one day :).

My latest project at work is Cassandra, a distributed, eventually consistent, column oriented data store. It's somewhere between Dynamo (Cassandra's original author worked on Dynamo), and Google's BigTable. It was developed as an internal application at Facebook, later open sourced, and is now an Apache incubator project.
The external interface to Cassandra is thrift-based. Thrift is a framework for creating network services, services that communicate using a compact binary data format. It's similar to Google's Protocol Buffers, but with more of a focus on RPC, and greater language coverage, (much greater actually). The bottom line, any application that uses Cassandra for structured data storage is going to need Thrift. So, I filed an ITP (Intent To Package) and have started work on packaging it for Debian.
Thrift is an interesting project to package as it has an architecture specific application (C++), 6 architecture specific and 5 architecture independent libraries, and covers 12 different languages. That's right, 12.
I'm still somewhat undecided on a game plan; the options I've considered so far are:
I've already taken a stab at #1 and it didn't seem promising. #2 is an option I still consider on the table but I'm a little concerned that it could lead to a mess. #3 and #4 really boil down to the same thing, collaborating with others to package as much as possible while maintaining the standards everyone expects from Debian. I guess I'm currently leaning toward some variation of #3 or #4, probably through the use of collab-maint or a dedicated Alioth project.
For the time being, my efforts can be tracked in Git here, so drop me a line if you're interested in joining the fun!

A co-worker of mine uses one of the stranger keyboards I've seen, a Kinesis Advantage.
He picked it up his after a bout with tendinitis and was sold on it. He was kind enough to let me borrow his spare for about a week so I could try it out. It's been an interesting week. :)
The Advantage differs from conventional keyboards in a number of ways, the ones I think most relevant are:
Ckey is directly below
D, not below and to the right. Moving your fingers from their keys on the home row to the corresponding keys above and below is a much more natural movement.
Altkeys are positioned within reach of your left thumb, your right works
Down, in addition to another
Controlkey, and a
Windowskey (which I remap to
Alt). This really makes sense if you think about, why waste two perfectly good fingers on the same key, when you could put them to use and eliminate all of that reaching.
I'm not going to lie though, it does take some getting used to. The biggest problem I had was
Backspace, which are the right-most thumb key, and left-most thumb key respectively. Prior to all of this I heavily favored my left thumb for striking the space bar, and muscle memory is a bitch when it causes you to
Backspace when you meant
Other points of frustration were the tilde/back-tick key (located bottom-left instead of top-left), and the left and right bracket/brace keys (located bottom-right). These keys are used a lot in a shell or when coding, which probably made the pain even more pronounced for someone like me.
I managed to force myself to use nothing else for several days, at which point I felt I was doing quite well. I still had the occasional problem here and there, but it seemed like I was well on my way to normalcy. Then I tried using the built-in keyboard on my laptop. Wow. Epic fail. It took a few more days and plenty of patience before I was able to move back and forth (and truth be told it's still a little awkward).
So was it worth it? Yeah, I think so. I've had RSI troubles of my own and a week of typing on this keyboard has felt pretty good. I've ordered one of my own to use at work, and I'll probably grab a second one for home.
