Slavery

Lars Walker makes an interesting point about slavery that I’d not previously considered:

The first thing to understand is that slavery is not an anomaly in human history. Our own society’s abolition of slavery is the anomaly. There have been very few cultures in the world – and those few very primitive – that did not practice slavery. Up until modern times the sophistication and greatness of a culture were almost always proportionate to its slave-holding.

This is because, up until the Industrial Revolution, slaves were the only labor-saving devices that existed.

He stretches the point slightly; water wheels and wind mills predate the industrial revolution by a good bit, I believe, and I suspect you’d have to define serfdom as a moderate form of slavery for his argument to hold. Nevertheless, there’s a lot of truth to what he says.

Read the whole thing, except possibly for the opening paragraphs on snow and roof rakes.

One of Descanso Garden’s two claims to fame is its Camellia Forest. Camellias aren’t native to California, but live oaks are; and camellias grow well in the shade, in acid soil. Many years ago, a man named Manchester Boddy realized that live oaks are really good at producing both, and that an oak forest is the perfect place for growing camellias.

The camellias are blooming right now, and in my in rounds I frequently see little mounds of camellia blooms in odd places. At first I was a loss to account for them; the ground under the camellia plants are frequently carpeted with fallen blooms, but not in little mounds; and anyway the mounds are never under the camellia plants.

Judging that garden gnomes are unlikely culprits, I have since concluded that these shabby little mounds are the work of other photographers. That remains conjecture, however, as I’ve never caught one at it.

The Other Shoe

I finally got my first piece of comment spam on this new blog yesterday. Or, rather, the first that got through the built-in spam filter. I hope that this isn’t a preview of coming attractions…..

Ship of Destiny, by Robin Hobb

This is the final book in Hobb’s Liveship Traders trilogy, and although it took me a long time to get through it I enjoyed it very much, and stayed up late on Saturday night to finish it. This is fairly typical for Hobb’s books: they are very long, and slow to get started; and the problems the characters face are painful enough and develop slowly enough that I usually prefer to read them in small doses. But constant acceleration can build quite a bit of momentum, and I usually end up reading the last couple of hundred pages in one or two big gulps. The effect is more pronounced when the book is the last in a trilogy, as this one is.

It would be difficult to say much about the plot without spoiling the earlier books, so I won’t; but I will say that the ending is quite satisfactory. It resolved the major conflicts (of which there were many), tied off the loose ends, and left me wanting more. Not too shabby, all things considered.

Mardi Gras

Yesterday was Mardi Gras, or Shrove Tuesday as we Anglicans call it, and consequently we feasted in proper Anglican fashion–but going out for pancakes. In years gone by that might have meant going to a church pancake supper, but that tradition has faded, at least at St. Luke’s; so we went to IHOP instead. And given that I’d not had either pancakes or hashbrowns in over a year, it was a feast indeed. Today, of course, I’m back on the wagon.

On the way to IHOP, I explained to our kids what Mardi Gras is all about, that it’s a time to feast before the penitential season of Lent. I explained that different people celebrated in different ways, and that in some places folks let their celebrations get out of hand and “behave very badly indeed.”

“What,” said my son James, “You mean like, they don’t say ‘please’?”

Panasonic L1 DSLR

Now, I’m very happy with my Lumix FZ5. I’m taking some great pictures with it, and having buckets of fun. Still, sometimes I wonder if I’d like to take the plunge into the world of DSLRs: Digital Single Lens Reflex cameras. The “digital” in “DSLR” is obvious enough; the “SLR” part implies that the camera takes interchangeable lenses and has a “through-the-lens” viewfinder. In short, DSLRs are the digital equivalent of the serious 35mm cameras of yore.

My FZ5 has a number of advantages over any DSLR. Because it has a smaller senser, it’s got a much deeper depth-of-field at larger apertures; that makes it easier to take pictures with an extended depth of field without using a tripod. Its built-in 12x zoom Leica lens gives me the ability to shoot both telephoto and (somewhat) wide angle without changing lenses. It’s both light and compact, so it’s reasonable to carry it around me all over the place. In short, it’s a great camera for taking snapshots of the kids on family excursions, and with its manual features and outstanding lens it’s also a great camera for serious shooting.

Moving to a DSLR would buy me a number of headaches. You can swap the lenses on a DSLR; but on the other hand, you pretty much need to swap lenses to get the range of focal lengths my FZ5 has built-in. Plus, when you swap lenses, dust has a chance to sneak in and collect on the (electrostatically charged) sensor. In Understanding Digital Photography, Bryan Peterson explains that the first thing he does when he loads any new image into Photoshop is examine the whole thing at 100% and remove any dust specks. Ugh! And of course the ability to swap lenses brings with it the need to buy lenses to swap. A typical lens might cost almost as much as my FZ5 does.

When you use a DSLR, you can look through the lens, and see precisely the image the sensor will see, which is very cool. But unlike my FZ5, you have to use the viewfinder; the very design of your standard TTL viewfinder means that the current image can’t be displayed on the camera’s LCD. I’ve taken lots of neat pictures that I simply could not have taken if I’d had to look through the viewfinder to do it. During my recent jaunt to Old Town Pasadena, for example, I took a lot of pictures with the camera held down near the ground. To do the same with a DSLR, I’d have had to lie down on my stomach–and given the state of the some the alleys we were shooting in, I’m simply not that dedicated to my art.

On the other hand, DSLRs buy you a lot too. The sensor is larger, which means you need to use much smaller apertures to get equivalent depth-of-field…but that just means that you’ve got much greater control over your depth of field. I like that. Because you can swap lenses, it’s much easier to take extremely wide-angle and macro shots. It’s more work…but you can do more, including things my FZ5 will never do.

So happens, Panasonic has just announced its first DSLR: the Lumix L1. The full details aren’t available yet, but I think perhaps I’m in love. Please note: this is a DSLR with a through-the-lens viewfinder and a continuously updated LCD. You get the best of both worlds. Plus, it has a special cleaning system that gets dust off of the sensor each time the camera is turned on.

This is very new technology; frankly, I suspect I’d be wise to wait a year or so and see how it shapes up. In any event, the L1 is still in development, and the full specifications aren’t yet available. But if it proves to be a DSLR with the usability of my FZ5, I’m going to be extremely tempted.

Miles and Miles

Jaq has just revealed that he’s only read the first two of Lois McMaster Bujold’s “Miles Vorkosigan” series. Now, I realize that one can’t have read everything. As they say in Silverlock, if he hasn’t read Bujold, it’s because he’s read other stuff.

But Jaq–yes, I’m talking to you!–you need to understand that when a new Bujold book comes out, it’s a major event at our house. Everything stops for three days or a week while I read the book aloud to Jane. That includes the Vorkosigan books, which are simply outstanding. Now, you’ve evidently read Shards of Honor and Barrayar, which these days are usually published in a single volume, Cordelia’s Honor; next, you must find a copy of Young Miles, which similarly combines two (or maybe three? I don’t have a copy) of the chronologically earliest books involving Cordelia and Aral’s son Miles. Trust me on this, Jaq, The Warrior’s Apprentice (the first selection in Young Miles) is everything you’ve been looking for.

In fact, it’s beginning to sound like a darn fine way to spend the afternoon.
