Personal Servers, Bluetooth, and Key Fobs

Posted by Doug Fri, 05 Dec 2003 16:12:00 GMT

The project I’m on at work is basically creating a customized PC fit for use in an Operating Room. It takes an amazing amount of effort to put pieces-parts together that the FDA thinks is OK. Our “infant mortality test” for the constructed machines uses a USB memory stick with all the tests on it. The manufacturer plugs the memory stick in, (assuming all is well) we automatically recognize the device and run the tests that are stored on it. It’s a fairly nice solution.

The point of sharing all that is I now have in my possession a 64MB USB key fob. I had been toying with buying one personally. My thought was to put things like my PGP keys, my big list of usernames and passwords, and other paranoid stuff like that. Of course, that would pretty much mean that I would need to have the key fob plugged in any time I was working at my machine. I’m too lazy for that. I’m already agrevated to plug in power, network, and external speakers on my notebook when I change desks. It’s the main reason I don’t use an external mouse, keyboard, or monitor. So, I’m having a hard time coming up with a good use for these USB key fobs. There’s just not enough space. What you can store in that space isn’t worth the effort. My boss likes to use them for sneaker-net. Most of our machines don’t have floppy drives. So tranfering data is pretty easy with the key fobs.

With all that in mind, I’m reading about More promiscuous data exchanges with strangers on my favorite news source The Register. It looks like there are several projects under way to build a device like Apple’s iPod, but with bluetooth and zeroconf/Rendezvous. What this gives you is something that can store many gigabytes of data with wireless access and very little setup required. Yum! I’ve always felt badly about all the personal data I keep on my company laptop. I’d love to pull it all off onto an iPod. Something like this would be great!

Of course what they’re talking about is using it as a pocket Napster for music sharing with people around you. That’s cool too I guess. Wired magazine has an article called Feel Free to Jack Into My iPod about a “trend” for strangers sharing iPods. I guess the novelty is listening to what other random people are listening to. We’re a fairly disconnected society for all our interconnectedness. What I mean is most of us get in our cars and drive to work by ourselves. We socialize with the people who’s desks are near us. We drive home, put the garage door down and don’t come out until morning. I think a lot of us pine for the days of “Mayberry” where people recognize each other as they walk down the street and stop to talk. I guess this is a good way to overcome that.

There’s a new article on Wired called TunA Lets Users Fish for Music that calls jacking into strangers’ iPods “so two weeks ago”. It’s basically talking about the same stuff this little note is. I guess I like the idea of jacking into someone elses iPod better just because it’s more of an intimate social thing than anonymously peeking into someone’s music list.

My New Server

Posted by Doug Thu, 04 Dec 2003 16:29:00 GMT

My partner, David Minor, and I have bought a new server to collocate. We started with an old sparcstation 20 in my basement with a road-runner connection and a UPS. We’ve tried virtual hosting, shared hosting, and dedicated hosting. We’ve come to the conclusion that being able to put your hands on your box is a good thing.

To that end, we’ve bought a 1U server by piece-parts. It’s got a Supermicro X5DPA-TGM motherboard with Intel’s ICH5-SATA Serial ATA IDE chipset, dual 120GB Serial ATA drives, a Gigabyte of RAM, and a 2.8GHz Xeon processor with space for one more. Of course, the common wisdom is that servers should be SCSI. We’ve done OK with IDE, but had some problems with the limitations of the IDE bus. We really wanted faster disk drives, but couldn’t really afford SCSI. It was going to be almost $500 more for a SCSI setup with dual 80GB drives. Serial ATA seems to be a good compromise between the high performance of SCSI and the low cost of IDE.

What we didn’t count on was how tricky it is to get Linux running on SATA. It turns out (like most things) it’s not that bad if you know what you’re doing. Linux on SATA seems to be fragile based on how you have your BIOS configured. Oh, yea. You need to be running a very recent kernel (we’re running 2.4.22-ac4; 2.4.23 didn’t seem to support our chipset). Since we were going all out (and it’s not every day you get the chance to setup a new box) we decided to use the Logical Volume Manager as well. I’ve put up pretty detailed notes on how I got DebianSataLvm all working together.

Logitech TrackMan Marble FX

Posted by Doug Fri, 14 Nov 2003 21:00:00 GMT

For those of you who don’t know, my primary “axe” is an IBM ThinkPad. I’ve quit carrying an external keyboard and mouse around with me. I’m just too lazy to manually plug in the keyboard, mouse, network, power, and monitor every time I sit down to my desk. So, I’m exclusively using the built-in LCD, keyboard, and “touchstick” pointing device.

So what’s the point of this? This week I’ve needed to use a keyboard and mouse on my secondary computer. Usually I just ssh into it from my ThinkPad. This week I actually need a mouse on the thing. I had to scrounge around to find one. The only thing I could find is this old Logitech trackball. Man do I love this thing! I didn’t realize just how much I miss it! It’s smooth, fast, and accurate. The trackball on it is huge. I don’t know for sure, but I’m guessing it has a three inch diameter. The only complaint I ever had with it was it didn’t scroll right in XFree86. There’s been some patches added that handle scrolling with only the fourth button (just like the MS-Window’s drivers do). Anyway, it makes me want to start carrying it around again… well, maybe not. But, it’s fun to use again.
