They're gonna build a Great Wall of Japan sooner or later, for some reason or another. Keep out The Fog or The Blight or whatever, the one that brings monsters or disease or it kidnaps people or something.

I feel like giant walls have been leaking into culture more. Pacific Rim, sure, but consider Shingeki no Kyojin or Darker than Black or Maze Runner, and those are just the recent ones. Giant walls are the new "human (female) locked away in a sealed box/chest, discovered later".

+ - Scientists Create Permanently Slick Surface so Ketchup Won't Stay in Bottle

Submitted by (3830033) writes "Much of what we buy never makes it out of the container and is instead thrown away — up to a quarter of skin lotion, 16 percent of laundry detergent and 15 percent of condiments like mustard and ketchup. Now Kenneth Chang reports at the NYT that scientists have just solved one of life's little problems — how to get that last little bit of ketchup (or glue) out of a bottle. Using a coating that makes the inside of the bottle permanently wet and slippery, glue quickly slides to the nozzle or back down to the bottom. The technology could have major environmental payoffs by reducing waste. Superhydrophobic surfaces work similar to air hockey tables. Tiny peaks and valleys on the surface create a thin layer of air between the liquid and the coating. The air decreases friction, so the liquid almost levitates above the surface, just like the hockey puck floats above the table. LiquiGlide’s approach is similar, but it uses a liquid lubricant, not a gas. ”What could be a solution that provides sort of universal slipperiness?” says Dr. Varanasi. “The idea we had was, Why not think about trapping a liquid in these features?” Dr. Varanasi and Mr. Smith worked out a theory to predict interactions among the surface, the lubricant and air. Essentially, the lubricant binds more strongly to the textured surface than to the liquid, and that allows the liquid to slide on a layer of lubricant instead of being pinned against the surface, and the textured surface keeps the lubricant from slipping out. “We’re not defying physics, but effectively, we are,” says Smith."

Echoing on the drink. Water is more than a physical filler; being hydrated helps you feel sated, you're closer to "taken care of", while being thirsty causes increased appeal towards food. It's probably safe to ignore those 8cups people, but water is worth remembering as a mindhack. Exploit it before/during meals as you see fit.

This is actually the angle I predict. Not just an alleged techguy, but deliberately assembling conditions such that "I don't have access to the key even if I wanted to.", kind of like breaking up a key into parts and splitting them among your lieutenants or minions or whatever.

We've been able to build workaround canaries and deadman switches with little tech, at this stage we can probably set conditions such that "I can't procure the key even under duress, an unknown third party/system has to re-equip me and will observe me first."

Not yet. In my dictionary, protolife (read, pre-life) is self-replicating assemblies, including prions but also tin pest and even fire. Any construct that has that seemingly self-preserving reproduction, which inadvertently causes population and sustained presence, the scoreboard of something well-evolved and adapted.

However, only protolife with variance can evolve. I'm not sure it's exhaustively impossible to see tin pest change: Consider some kind of unusual variant or alloy that is less susceptible to being eroded by water, and more importantly, populates as much and as often and either it reaches nearby environments or it is a "mutation" of some noticeable frequency. Some, most, or all tin pest would be of this variety. And yet ultimately, like GP said, this lacks real mutation, the chain of possibilities isn't there. It only coincides with sustained presence.

GP's prion is some kind of brown goo scenario, but it seems like it leans on an abundance of inert proteins, or protobiosphere. I still lean towards this endpoint because of increased variant options over tin by sheer chemistry, because "more stable" variants will probably be (inadvertently) leveraging properties that are more True Scotsman "life", like incidental locomotion. Or maybe they clump. Or, hell, I don't know, because disclaimer: I'm speculating out my ass and don't know shit about the subject.

Ha ha oh wow. Since when did this ever start showing up in statements? Last I checked we still have people (from plebs to politicians) saying crap like "We should show everyone's name on the internets!"

And even multi-million corporates saying crap like "Let's base policy around the user's location because we can tell where they are." Then some tech says something about "proxies and VPNs" and the decision makers say something about "Fix it. We'll sue. We'll lobby it into illegal. Do something."

You don't have to know tech, just know that things like "the (federal) LEOs can look the guy up" and "they can be controlled through their ISP" are not hard rules. That there are few hard limits to internet use at all. You can do whatever you want case-to-case but it's different when you try to declare encompassing laws. You don't have to know tech, just look at restrictive countries. You can control most people most of the time (techwise) but don't assume that's a reflection of your power, it reflects people using tech the easy (insecure) way.

Hopefully we'll dodge more bullets in the future. I'm glad we didn't set the wrong precedent on "an IP address is useful evidence but can not be equated to an individual".
