This is neat. Typealyzer claims to examine a blog (or presumably any webpage) in order to identify the Myers-Briggs type of the author. It correctly identifies me as an INTP, but doesn’t seem to get etselec.

robert johnson
Dear Amazon.com:
After buying the collected works of Robert Johnson, blues guitarist from the 1930s, the man who was reputed to have sold his soul to the devil to become the greatest blues guitarist ever, I really don’t think I want albums by Robert Johnson the 70s power pop musician. I know they have the same name, but trust me, they aren’t the same person.

at home in the (technical) universe
Some recent (somewhat) technical notes:
- A while back, I swapped the dead harddrive from my ipod with a compact flash card. Unfortunately, at the time, the biggest (affordable) compact flash was 16 GB, so I lost about half the capacity from my ipod. Not a huge problem, but it became more of one as I added more music. Yesterday, a shiny new 32 GB compact flash arrived and now I’m back to the nominal amount of space on my ipod, except that it’s all solid state and cool. From the technical standpoint, this was something of a PITA, since I didn’t have a windows or mac machine around to reinstall the firmware. My ultimate solution: 1) back up /dev/sdb (boot record and partition table) and /dev/sdb1 (firmware) from the ipod using dd; 2) put the CF in my laptop and format it (a camera would work just as well), this just normalizes the card; 3) put the CF in the ipod (or in the laptop); 4) write the patition table using dd; 5) edit the partition table using fdisk, set the size of sdb2 to be 32 rather than 16 GB; 6) write out the firmware to sdb1; 7) format sdb2 using mkfs.vfat. Voila – a 32 GB ipod CF
- If you haven’t seen it already, check out projecteuler.net. They’ve got a bunch of mathematically oriented programming problems online of varying difficulty. Good solutions should all run in 1 minute or less and generally take 100 lines of code or so. It’s a good way to get familiar with a new programming language and to exercise your brain. So far, I’ve done the first 70 or so problems – they don’t take too long, maybe a half hour each on average.
- Finally, I got the clutch in my car replaced yesterday. The mechanic said that it was in pretty bad shape and that the (plastic?) bearing the clutch uses had worn completely away. This probably explains why I’ve had no acceleration for the past year (or more?). I had forgotten what it was like to drive a decent car 🙂

Thinking about camera equipment
I started taking photography more seriously about ten years ago. I put down my cheap point and shoot film camera and bought an SLR body, a few lenses and some slide film. The great thing about shooting film (slide or print) is that you aren’t constrained by the quality of your camera. My first SLR was a used Olympus OM-1n, circa 1975. The OM-1n was fully manual – no auto-focus, no auto-exposure. If you didn’t want to use the exposure meter then you didn’t even need a battery. It was a beautiful piece of equipment, but it was also about as basic as you could get outside of a pinhole camera. It was a dark box that held and advanced film with a mount to hold a lens open for a set period of time. That’s it.
At the time I bought the camera, the basic advice was to buy a camera body with the minimum features that you needed and use the savings to buy better lenses. It was the glass in front of the camera and the type of film in it that had the greatest affect on picture quality. Two photographers using the same lens, one having a fully manual and one having a fully automated camera could each take similar quality images. That’s not to say that auto-exposure doesn’t make it easier to get the right aperture settings or that auto-focus isn’t useful when your subject is moving. Both of those things are true. But at the end of the day, they just improved the odds of getting a good shot. Your only real constraints were glass and film.
These days, I’m using a Nikon D80 digital camera body. It’s also nice. Definitely a lot more electronics – auto focus, auto exposure, various program modes etc. You can still set it in a manual meter mode, but it’ll never be a manual camera. If you take out the batteries, it’s just an inert hunk of silicon and rubber.
I was reminded of all of this when talking to Hunter a few days ago. He’s interested in getting a new camera body. I almost choked when I saw how much the body alone costs. My first thought was the old advice I heard when I bought my first SLR: buy a cheap body and good glass, your photography will be better for it. Then I realized that’s no longer always true.
One of the things that digital cameras have done is to turn the camera body into the equivalent of the camera body and the film. It is as if I had bought my Olympus OM-1n and had to always use Fuji Provia 400. Wait – what if I want a better film, say Velvia 50? Too bad – you should buy a better camera. Well, digital cameras are just like that. Different camera bodies have different sensors of varying quality. It’s not just a matter of megapixels, but also ISO equivalents and noise reduction. We’ve just entered a world where the quality of your pictures is constrained by both the lenses you have and the camera body you own. What’s worse is that the camera body itself will become obsolete. Unlike my OM-1n, there will never be a market for 25 year old camera bodies. Lenses, yes. Camera bodies, no.
This isn’t all terrible I suppose. The commoditization of the camera body is making better photographic equipment more affordable. Right now, affordable digital camera gear can produce better pictures than can be had on print film. High end cameras are better than slide film and in a few years, affordable cameras will also be better than slide film. I just find it a shame that digital photography has locked us into a world where the amount of money you have will determine the quality of your pictures.

New guitar
Over the past few months, I’ve been thinking about getting a new guitar. I’ve been heading up to High Strung in Durham and have played with maybe a dozen different models, but the one I kept coming back to was a Blueridge BR-243. It’s got a beautiful sound and it’s very comfortable for me to play. The body size is “000” as opposed to the more common dreadnought size (like my first guitar) which means it’s easier to get my arms around and the shorter neck makes it easier to reach all of the chords. The back and sides of the guitar are mahogany
Well, I’ve got a birthday coming up and Christmas is around the corner, so last Friday I went ahead and bought the BR-243 as a combo present. Unfortunately, High Strung didn’t have the case which fits the guitar in stock, so they gave me a loaner while mine is being ordered. I believe the case fits a dreadnought sized guitar, so that might give you some sense of the size. I should also post a picture of my old guitar with the new one.
Anyway, I’ve been playing with the guitar for a few days now and I love it even more now than I did in the store. I also finally went online to see what other people thought (I didn’t want to overly influence myself 🙂 ) and it got great reviews, particularly for the quality at its price point. At this point, I think the only problem is that I’m not much in the mood to work – I would rather go home and practice the guitar 😀
