bean used to post long and in depth posts into the SlateStarCodex Open Threads, then someone helped him set up his own site, and here we are. He organizes meetups at Naval History sites too.
I changed my email address in ~200 accounts and only had trouble updating a few: BuiltIn, CPUID, Flickr, Kakao, JCrew, Nord, and Steiger.
After I contacted Kakao support, they asked for some documents. Then they called me to verify the details. A day or two later, they updated my online profile with an editable email field, so I was finally able to update my email address.
When I contacted JCrew chat support, they performed the update immediately and emailed me a temporary password from noreply@demandware.net.
Flickr and Steiger were also happy to help. TBD on the others.
So I can't think of any accounts that don't allow an email change either. But you might have to jump through some hoops.
Look at the Dry Stone Wall Association of Great Britain, or The Stone Trust in the United States. These organizations still teach traditional methods of dry stone walling which cover a lot of these techniques.
This isn't really a proper wall though, it's a single thickness stack. I don't think it could handle any lateral force at all without toppling. If this machine could build a double skin wall with batter, wall heads, and hearting throughout the center, I'd be really impressed!
Not true. A well built fieldstone wall is massive, we estimate around .5T per linear yard when we build one to 4ft. with cope stones. Sheep will not knock it over, but cattle can. For that reason, through-stones are allowed to protrude a few inches on normal pasture wall for sheep, but you should make them flush on walls for cattle because the cows will try to use the protrusions to scratch themselves and could knock the wall over.
A well built wall doesn't appear unstable. One of the tests is whether or not you can see any daylight through the wall, and the wall should easily support the weight of several people leaning against it.
That city has a tiny fraction of the population density, commercial activity, and industrial transport of Chicago, they're really not comparable. Transporting people and goods over large distances by bicycle doesn't scale very well.
throwaway5959 mentioned travelling to their grocery store. I'm going to guess that their grocery store is not on the other side of Chicago from where they live. How big the city is that contains the grocery store doesn't seem directly relevant to that or does it ?
Without for profit, for export, weapons, smaller entities that cannot support the industrial base to produce the means for their own defense would be at the mercy of any power who could. Self defense is a right, and the means of self defense should be widely available. Ensuring the vulnerability of the weak is morally reprehensible.
I didn't say the weak should remain vulnerable. That is putting words in my mouth. How are the weak going to protect themselves with this German tank, they can't afford it.
If we cared about the weak, we would ensure they aren't harmed. The world isn't interested in that. For profit weapons systems aren't interested in the weak, they are interested in the well funded.
How much conflict has the low cost AK47 (7$ on the world market) enabled?
