Hang in there, Los Alamos

As I write this my family is under mandatory evacuation orders in Los Alamos, NM. The good news: the last major fire, which burned the homes of 600 families, left a low-fuel swath around much of the town. The bad news: this fire is fucking crazy.

So, hang in there, guys, and be safe. I’ll write more later, when I’m not supposed to be working.

A Rambling Blog

A couple of years ago I became fed up with my Web hosting provider. MMHosting had been great, but then came the outages, and the complete lack of response from their support people. (At the start of my stay with them, I had been mightily impressed with their customer care. That ended.) Then there was the time Muddled Ramblings was mentioned on a very popular blog and my hits soared. They turned me off.

I moved to a new, very inexpensive host called iPage. It was great, until the outages, which could last a day or more. When I asked what the problem had been and what they had done, they were vague. “No, really,” I persisted, “I understand the jargon. Tell me what happened and what you did to make sure it won’t happen again.” I never got an answer.

“You get what you pay for,” I reasoned, and iPage was wedging me onto an already overcrowded server and there just wasn’t enough computer there to handle all that traffic. Giddy with a new income stream, I decided to upgrade. The way to avoid getting wedged onto an overcrowded machine is to cough up the bucks and reserve a portion of a machine that is yours and yours alone. It doesn’t matter what any of your neighbors on the box do, they can’t take your resources away from you.

The downside to this approach is that you can’t borrow resources from your neighbors, either. For reasons I still don’t understand, my virtual server went nuts every once in a while, cranking away and eventually running out of ram and descending into a hellish limbo of non-Web-serving confusion. I’ve gone over all my stuff and I can’t find anything that would cause that, but there must be something. (It might be coming from outside; perhaps China still hates this blog, and throws a half-assed attack at it periodically. They do that shit. I expect it’s something more local, however.)

So the money I was throwing at the problem wasn’t helping. It was time to weigh my options again. The step up from renting a dedicated slice of a server is to use the whole damn machine. Naturally, this costs a lot more, since there’s one customer per machine.

Except when it doesn’t. Enter my new best hosting pals, MacMiniColo.net. For the price I was paying Green Geeks, I get more than six times the server, and it’s MacOS, which means all my experience setting up servers with MacPorts pays off. (I’m a big fan of MacPorts. It’s not always quite as easy as they make it sound, but usually it is. Tonight I needed to add SSH2 support in PHP, and all I had to do was type sudo port install php5-ssh2 and that was that. I’m not even sure what SSH2 is (as opposed to SSH) but it simplified the WordPress AutoUpdate process.)

There were a couple of hiccups getting everything running (I set up jerryseeger.com as a WordPress install first to pave the way), but once everyone agreed where the MySQL socket was it was Holiday On Ice the rest of the way. The last step, getting AutoUpdate to work in WordPress, was something I’d not managed on the CentOS virtual server at GreenGeeks. Now it’s cake.

So, I’m pretty happy. I’ll be watching for the midnight-runaway problem, and if the extra horsepower doesn’t solve it (if it even happens at all), at least now I know that there is nothing on this box I don’t control.

The Question I Really Wanted to Ask Tonight

“So, are you guys prostitutes?”

Road Trip by the Numbers

My sweetie and I just made a quick road trip from here in San Jose down to Tucson, Arizona, and back. The light of my life happens to be the light of other people’s lives as well, and one of her closest friends has been having a tough time of it lately. It was time to go lend a bit of moral support, and to introduce me to part of my sweeties (non-genetic) extended family.

Time was limited, however, and cash not as plentiful as we would like, factors that combined to make this a long drive with little rest. Here are a couple of interesting stats:

Waking hours spent driving: 50% (about 33/65)
Increase in car's mileage: 5.5%

That second number may not seem that significant, until you realize the car is ten years old:

Miles per day, first ten years: 33700/3650 = 9.2
        (includes a road trip from San Jose to Los Angeles)
Miles per day, last four days: 1880/4 = 470

The last stat of note:

Beers consumed: 0

Yeah. Next time, we’re flying.

Taking Pictures of the Wall

I’ve said before that nobody was more surprised than I when I outgrew my camera. Well, that’s nothing that a regular paycheck can’t solve, and now I not only have a better camera (only four years out of date!), I have other gear as well. The most significant addition to the toybox has been fancy strobes and an assortment of accessories. No more shooting with 60-watt desk lamps with long, long exposures (unless I want to).

Now I have plenty of light, but last shoot I was frustrated, needing to move an umbrella back for better coverage, while at the same time needing to move it forward to make the edges of the shadows softer. Harlean’s fictitious feet were often in shadow. There’s a toy called a softbox that most photographers use in situations like this, but I don’t have any of those (yet), and in my little living room/studio there really isn’t room for them. So, I need to get the most out of my umbrellas.

One of the more interesting pictures of the backdrop. Seriously.

The first step is figuring out just what they do. To this end my faithful sidekick set up a large blank surface and I spent the afternoon taking pictures of the way the light splashed on the wall as I moved the light in and out, and what effect shifting the light in the focus of the umbrella had. I also experimented with grids that limit the dispersion of the light and with some of my other new toys.

Important to the exercise was the ability to see the result of each shot. My camera has a pretty large LCD, but for judging lighting I just don’t trust it. I needed instant feedback on a larger screen. Happily, Canon has software to allow the camera and my computer to talk to each other in real time. Take the picture, it’s loaded onto the computer and appears on the screen. The problem: Canon is run by idiots and you can’t download and install the software. They have updaters, but you have to start with an install from the CD that came with your camera. I had a CD. It’s around somewhere. Maybe in San Diego. A while back I got them to send me a second CD which I think is in New Mexico. Yep, they’d rather mail me a CD than let me download the stupid software.

Canon’s logic, near as I can figure: “We can’t let just anybody download this software! Non-Canon users might get hold of it and… like it and… wish they could take advantage of the features that only work with a Canon camera and… buy our cameras. We can’t have that! (Wait, what?)”

Anyway, it turns out the “updater” is a full installer that’s been jiggered, and once I learned how to un-jigger an older installer and then update with the newer updater, I was good to go. On with the experiment!

I have to say that the results were not always what I would have expected based on my Physics classes. I learned quite a bit: 1) I should not have had any trouble lighting Harlean’s feet. 2) moving the light in and out of the umbrella’s focus affected brightness more than the spread of the light, and 3) there’s only so long you can take pictures of a blank surface.

"Bunny Head" shot with similar light to the blank shot above.


If you will recall, the other lemma (half of a dilemma) stated above was that I wanted to keep shadows soft. Larger light sources make softer shadows, so you can soften shadows by moving the light closer to the subject (so it appears larger). My experiments shooting against a blank surface couldn’t give me any insight on that front, so once I was more comfortable with the way the light spread, it was time to put something in front of the lights that had features that cast shadows. Enter the foam head with bunny ears.

(I’ve been trying to come up with a technical justification for the bunny ears, but in the end I just thought they’d be fun. And! Ooo! The pink lining gave me a way to judge color saturation. So there you go. The bunny ears were critical.)

Talk about a tough subject to photograph. Bright, shiny, pure-white objects are unforgiving to say the least. Get enough light to bring out texture, and you’re getting harsh reflections as well. I spent an hour or so moving the light (singular) around in a scientific fashion, comparing the results after careful variations. Then I got tired of that and just tried to take a few good pictures.

Some random samples from the head-shooting experiments. I seem to have grabbed dark ones. There are some interesting differences if you know how the light was changed each time.


After that exercise, I had to get a picture of the whole setup. Out came the old camera, set up on a cardboard box. I set the shutter to one second so I could hear it click and take a picture with the main camera (causing the flash to pop). I spent maybe half an hour on this one stupid shot, trying to get cool shadows on the floor, a nice look at the laptop screen, and a good feeling for the surrounding room. The light of my life pointed out a fun visual element in one picture that then became a requirement for the final. I’d take a few shots, go back to the big computer, experiment with cropping, decide I could do better and go back out to the studio again.

Experimenting with lighting, using a foam head and bunny ears.


A little technical geekery: those looking closely might notice that the background appears a lot darker in the photo on the laptop screen. The light is much closer to the head than to the backdrop, so the head gets more intense light. When the exposure is correct for the bright white head, the background is underexposed.

I never got the perfect shot. Perfection is a thankless bitch, remote and unattainable. We all chase her, and some get closer than others. The question is: will you learn from her rejection? Am I a better photographer for spending a day taking a couple hundred pictures (and looking carefully at each) that no one will ever see? I hope so. We’ll find out soon enough.

And that, my friends, is how you spend a Sunday!

New Album Out!

I haven’t seen the cover for the Foo Fighters’ new album, but if the song I heard today is any indication, it’s pretty easy to imagine what it looks like. Here is my humble rendition:

Obvious in Retrospect

There’s a show coming out on ABC, the title of which escapes me even though I saw an ad for it less than a minute ago. Here was the pitch to the network executives: “It’s M*A*S*H, in Iraq, only patriotic.”

That phrase, right there, with maybe a dash of crime drama, would have got you a $50 million budget (if you could tell the right person). But you didn’t think of it. Alas, neither did I.
