Food storage of the past
Fermentation. Fermentation produces acids and alchohols that inhibit spoilage, thereby increasing the useful life of food. The classic example is sauerkraut (and cousins such as kim-chee) which, if made in the late fall, can keep all winter long, supplying the dinner table with tasty vegetables. It's not just about veggies - salamis and cheeses have been a big part of the European diet for a long time.
The cellar (and related spaces - stored winter ice, cool stream houses, etc.). The cool food cellar was important in the summer, when everywhere else was warm. But even in the winter, they allowed produce to keep longer in closer to ideal conditions.
Heartier crops. The fruits and vegetables we eat today are not the same strains that people ate a century ago. With the commercialization of the food supply, it made economic sense to pick foods for their shelf lives, durability, and appearance, vs. flavor and nutrition. One obvious example comes from apples:
in the 1970s, you could either get red "delicious" or golden "delicious". The "delicious" brand apples were chosen (and subsequently bred) not for their flavor, but for their color and their ability to last in cold storage until the next fall, providing "fresh" apples all year round.
When I switched to organic produce a few years ago I noticed a similar change - the food didn't look as smooth, uniform, shiny, and perfect, but it tasted so much better.
While the "delicious" strains had a long shelf life in cold storage, we also see that today's fresh produce doesn't last as long because of our farming practices. Healthy crops grown in rich soil are able to resist spoilage longer. I keep thinking of a blue-water sailing book from the 1970's, where the author suggested carrying produce on board in well-ventilated space, because it would last for months. That's unusual today.
On the shelf. I've seen a couple historical examples of keeping foods right on the shelf at room temperature, instead of refridgerating. One comes from the movie Big Night - in the last scene, Secundo picks up a bowl of eggs that were just sitting out, and makes breakfast. Another comes from the Aubrey/Maturin novels I've been reading, where a character will often pick up a peice of meat that sat out all night (or longer), put it in his pocket, go for a long hike, and eat the meat for lunch.
I'm not sure what to make of these examples, other than a suspicion that our ideas about what is required for safe food storage may be a bit overzealous.
Dump the fridge? I've been looking at listings for houses built in the 1920's and before. I find them beautiful. I also see that the fridge never fits. It sticks out in to the middle of the kitchen, or it's in the next room. I think it would be interesting to move towards fridgelessness one day. For the meantime, I'll try to take comfort in the thought that I only need 1/5th of a fridge, since I share mine with 4 others.

Decluttering the study
Today it's Reid's bedroom, but still full of stuff from those days. We thought he might like to put his clothes in there
- A big box of VHS and print porn and in storage there. Gone.
- Julie's old SLR camera. 9+ years unused. Given.
- Blank paper. In notebooks, pads, loose, etc. What is this for? Donated.
- A whiteboard w/ markers, eraser, and cleaner. Given.
- Dozens of "home improvement" magazines. Recycled.
- 7 milk crates that were holding all this and more. Only 2 are holding anything any more.
- PC speakers with subwoofer that may or may not work. Need to find a home for these.
- Family photographs. Saved.
- random CDs that were missing their cases, and cases that were missing their CDs. Matched & ripped; ready for storage.
- and much, much more!
Now the closet is almost completely empty. I'm not sure where the milk crates will go.
I also decided to get rid of about 1/2 of the books I own. That's not a huge difference, as previously all my books fit on one shelf. Now they share a shelf with other books.
Damn, it feels good.
Next up:
- the "cat room" was the victim of random accumulations ahead of the babies' birthday party. Need to clear that out.
- Still a few "junk boxes" that need to be sorted out

I want Wiki! (Part 2)
Q: My chosen profession has begun to look like "part of the problem" rather than "part of the solution." I'm beginning to feel obliged to abandon it, as a matter of conscience. Do you see it this way?A: You're wondering if we wouldn't be better off if your chosen profession didn't exist at all. A young film maker once expressed the same reservation to me (unknown to the general public, film-making is a tremendously pollutive business). I told him what I'll tell you: WHERE WOULD WE BE IF EVERYONE WITH A CONSCIENCE GOT OUT OF HIS CHOSEN PROFESSION?
We MUST HAVE film makers like him---and people like you in your profession! We must NOT cede key professions to people who care about nothing but profits.
Don't assume that DQ is telling you to keep doing exactly the same job you're doing today. You can change how you do your job, to address these concerns. You can also change jobs in the same profession.

Evolution has halted
I've heard people say something like this before, but usually it turns out that they just don't understand what evolution is. They typically mean something like
In the 'wild', people who (can't see / can't walk / have regular seizures / have acute ashma / have low sperm counts / etc.) would not survive to reproduce, thus the human species would tend to select for the opposite traits. Thanks to modern medicine we allow these traits to continue to occur, and potentially proliferate in our gene pool, resulting in a weaker human population over time.
Or to put it colloquially, "our technology means that the human species is getting worse." (The problem with that statement, of course, is that evolution doesn't say anything about "better" or "worse" but merely about "more fit" and "less fit" to survive in a given niche.)
Consider that civilized humans transform available land from its wild state to a food-producing state. We do this rapidly and efficiently, thereby allowing us to produce corresponding increases in food supply. Whereas non-civilized peoples have allowed food supply to limit their numbers ("living in the hands of the gods"), we have effectively removed the limits on food availability for nearly all humans on earth. In this way, a limited food supply is not a significant factor in the gene selection of civilized people.
Consider that civilized humans will, without hestiation, obliterate obstacles to increasing food supply for humans. Cows like to graze pasture, so we'll destroy rain forests extremely rapidly ( 100 acres / minute!), destorying the "inconsequential" life in that area, so that our cows may graze. If wolves show interest in our cows, we won't just defend the cows when the wolves approach. We systematically seek out and destroy all wolves, nearly eliminating them as a species, on purpose. We make the decisions about which species thrive and which are decimated. For millions of years, the selection was made by a complex mix of natural forces; for the past 10,000 years, we have taken that decision in to our own hands. We decide who lives and who dies.
The universe if full of diversity. Each blade of grass is unique. Each plant is unique. Each mammal is unique. Each species is unique. Just as the Law of Gravity is written in every particle of matter, the Law of Life is written in every living thing. Diversity of life is at the essense of that law. Diversity of life is at the essense of the theory of natural selection. Civilized man has dramatically reduced the diversity of life on the earth, by driving some species to extinction, while we allow others to proliferate almost unchecked. The result dismantles the normal functioning of evolution by natural selection.
Natural selection is the process by which favorable traits that are heritable propagate throughout a reproductive population: individual organisms with favorable traits are more likely to survive and reproduce than those with unfavorable traits. If these traits have a genetic basis, then the genotypes associated with the favored traits will increase in frequency in the next generation. Given enough time, this passive process results in adaptations and speciation (see evolution). Natural selection explains why living creatures seem to match their environmental niches so well.
Natural selection is one of the cornerstones of modern biology. The term was introduced by Charles Darwin in his groundbreaking 1859 book The Origin of Species, [1] by analogy with artificial selection, by which a farmer selects his breeding stock.
Finding hope in criticism
Recent population trends indicate a dropoff in fertility rates in most regions in the globe; many demographers claim that increased women's autonomy and access to reproductive technology is responsible for the decrease, and that such trends actually bring fertility below the " replacement rate" in many industrialized nations. Some argue that people in industrial societies have less of an incentive to "over-reproduce," as children are a net economic drain, unlike in agrarian societies. In this view, it is possible that population levels will become self-limiting if high rates of reproduction become irrational and avoidable.
- too busy conusming products and media to breed
- too busy working to pay off the debt from the former
- exposed to polutants that interfere with fertility or libido
Is mass starvation the answer?
Today, I think I have gotten past the initial hump, and can at least articulate what I believe Quinn is saying. Most of what he said in Ishmael seemed pretty reasonable to me. The ideas are not complex, even if they are outside my normal arena of thought.
However, there was one bit that I got stuck on.
He talks about the relationship between food supply an population. That for any population of a given species, if you increase the food supply, the population will grow to match, and if you decrease the food supply the population will shrink to match. He says this is true for all species, and that includes humans. What our culture has done, via Tolitarian Agriculture, is to continually, and dramatically increase our food supply for 10,000 years.
He also makes a strong case that this behavior is a problem - that it's not sustainable. In fact, we have long since past the point of sustainabilty. To attempt to maintain current behavior will result in our extinction, and soon -- Quinn says 100 years if we keep going the way we're going.
When I read this, I thought it sounded like Quinn was saying we should reduce the food supply available to humanity, which would in turn reduce the human population. That is, people need to get busy starving to death .
Well, that's not something I can accept very easily, for a number of reasons:
Starving hurts. Really, it's a terrible way to go. I hate it when dinner is late; I can't imagine the agony of dying of hunger.
Who decides? Some will go hungry, while others eat enough. Who chooses? Judging by our past behaviors, it will be the elite that chooses, and they will choose themselves & their friends to eat. That is, the haves will have food, and the have-nots will not have food. The fact that I would almost certainly be in the 'haves' is no comfort to me. Anyway, this is something that no one has the right to choose. As Quinn says, "who lives and who dies" is a matter for the gods; the fact that we think we are wise enough to make that choice is the reason we ended up here in the first place.
The system would be abused. Duh. No matter how fair the system could be, someone will use their power to abuse it.
Still, perhaps we can convince ourselves that it's OK for mass starvation to happen, because:
a) today lots of people are already starving
b) the result would be "better for humanity"
But then I consider:
It's only temporary. If we could reduce the human population by 90% this way, the remaining 10% would have little motivation to stick with the program, and our numbers would grow again. We're doubling every 37 years, so it would take a bit over a century to restore the current population.
Then I consider what I think I know about Quinn. He is not trying to deliver a doomsday message, but instead a message of hope. It just doesn't seem to fit him to say that he's suggesting we starve 90% of the population. He must have a better idea in mind.

Reid likes pizza

Yesterday's involved a long ferry ride. I didn't let him eat on the boat because he was experiencing some motion sickness. When we arrived we decided to eat at a pizza joint. Reid ate a large slice, and insisted he was still hungry. The second slice was even bigger, so I grabbed this snapshot.

OK, I'll write
Lee also says:
You solve problems all day. Even if it’s a relatively simple solution
(script, house repair tip, way to get better gas mileage,) write about it
anyways. Those looking to solve that same problem in the future will thank
you.
OK, here I go:
script
My PowerShell prompt:
function prompt{
Write-Host ("PS " + $(get-location) +">") -nonewline -foregroundcolor Magenta
return " "
}
house repair tip
If you decide to run new low-voltage wiring (like ethernet), go ahead and pull way, way more than you think you need. The work to pull the first wire is huge. The additional cost to pull a bundle is small. I recently pulled:
- Cat-5e (ethernet)
- Cat-5e (phone)
- Cat-5e (spare)
- RG-6 (video)
Now I think I should have pulled another RG-6, which people seem to like for satellite.
I'm wondering if I can use the spare Cat-5e to run line-level audio for whole-house music.
(Great thanks to my brother for doing the messy under-house work.)
way to get better gas mileage
Don't drive. Walk, bike, bus, or don't go in the first place. This is so much more effective than anything else I can offer.
When I do drive, I've picked up the following highly annoying habit: I go really slowly up hills. Specifically, I try to take it easy on the gas up a hill, even if that means I gradually lose speed. With an automatic transmission, I try to keep as much throttle on as I can without it downshifting. This does seem to annoy other drivers, so I try to do it when there's no one right behind me.
When I approach a red light, I get off the gas way, way early, which saves some gas. I'll even brake a little, from far away, in order to still have some momentum when the light goes green and other traffic starts to move. This doesn't make me any later, but somehow it still pisses off the other drivers, who then drive harder to get past me. So it may be a net loss.

What is the Yoga of Stretching?
One example of my learning: I realized that if I'm going to get physically fit, I need to find a way to do it without it being work. Going to the gym for an hour and doing the stairmaster just doesn't work for me. I know I won't do it. What I've done instead is integrate activity in to my life in a way that meets other needs as well. For example, I bike my son to school. I enjoy our time together, and I like the oddness of it.
One aspect of my physical health that is pretty far from where I want it to be is my flexibility. I can't remember ever having been able to touch my toes without bending my knees. Heck, I can't remember being able to reach my ankles.
I find that I don't really enjoy stretching. I've taken yoga classes, but they are more like aerobics classes with a different set of movements. The Yoga of it seems lost. Instead, I'm trying to find an activity that is interesting for some other reason, and will improve my flexibilty.
The only thing can think of so far is swimming, but I'm not sure. Does swimming make you more flexible?
Any other suggestions?
Edit: This page: http://www.thefactsaboutfitness.com/research/oldstretch.htm seems to suggest that they know something interesting, but they aren't saying what unless you pay. And I ain't paying.
Edit 2: When I imagine "flexible", I think of the opening scenes in the Firefly episode Objects in Space. River walks in to the cargo area, and bends over to consider an object on the ground. She could probably put her forhead on her shins.
