Comment Re:NEMA 4X is all you need? (Score 1) 202

I can add that with high pressure jets you cannot rely on rubber or thermo-plastic seals, the gaskets have to be metal to metal.

For heat dissipation the whole construction should be in metal and you will have to maximise the outside surface area like with ribs.

The first thing that comes to mind is a cilinder with a screw cap on one end and fins on the outside.

Comment Re:Distributed social networks won't work. (Score 1) 269

You're acting like a social network is a web site. It's not, it's a fabric. If you want to be able to do this type of editing, fine, put up a web page, but don't try to pretend that you posting something that makes you look like an asshole, and then me commenting on it, calling you out for being an asshole, and then you changing the original posting so that it looks like I'm the asshole for engaging in an ad hominim attack, is somehow OK.

I'm not sure how this relates to anything, or how "put up a webpage" makes any sense at all (every social media site I've heard of uses a webpage of sorts..)

You're being disingenuous, or intentionally obtuse. You putting up your own web page so people can see your rants is a far cry from some putative distributed Facebook competitor that exists only to get out from under the "heel" of what the OP dislikes as properties of Facebook he wants to make as architecturally difficult as possible to implement.

There's nothing about "social media" that says "permanence." Snapchat for example does the exact opposite of permanence and automatically deletes things for you.

No, that's a feature of snapchat in particular which is considered by most people to be a means of evading law enforcement, at worst, and the same thing as having an expiration date where the service effectively has a sliding "we're going out of business, sorry" at best. Think MySpace.

Ephemeral is a feature to only a very few.

It still falls under the label "social media" though.

That more of a consequence of the inability of the journalists to classify it, and so they pick a lexicographically "a cherry is like a tomato, because both are red and fruit" close thing, and call it that. IT also sells itself as that, because if you can sell yourself as that, you can pretty much get VC funding.

I can't just erase our shared context from my memory, if I decide Bob is a Nazi after the fact.

No, but you can go ahead and not tell all your friends that Bob's a great guy and cut him out of your life. I'm not sure how any of that has anything to do with any specific communication tool though. The internet does not work like a human brain, for better or worse.

Am I just supposed to "de-friend" everyone?

Or you could just you know, put Bob himself specifically on ignore or whatever equivalent exists. Sure he might still show up in your friends-of-friends lists but he shouldn't be able to shower your wall with hate speech (though again, you should really be questioning your associations if your "real" friends are perfectly OK with Bob's rants.)

I think I pretty much want to out Bob as a Nazi everywhere. I want to punish him for being a Nazi by ensuring he is socially ostracized to the point that he gives up being a Nazi because he's decided that his perceived costs outweigh his perceived benefit. It'd also be nice if he can't pass on his heinous meme to another unsuspecting person by being sly about slowly indoctrinating them, and it'd be nice if any woman who might get into a relationship with him and have his kids would be able to make that decision on the basis of complete information. People frequently make an emotional or financial investment in a bad venture, and then rather than cut their losses, they "throw good money after bad".

This is how gambling addiction works. It why people stay in abusive relationships.

By allowing the rewrite of history (discussed earlier), you remove the need for the social lubricants of politeness, civility, and (possibly pretend) rationality, which are required in real-world interactions.

Except this is explicitly a network of "friends." If you don't like someone, don't friend them.

You are either an old anarchist, or you are otherwise not very knowledgable about how younger people view "friends" on Facebook. Calling them "friends" is a terminology Facebook uses; these are not "friends" in terms of "web of trust". This is not like a PGP key-signing party.

Younger users accept *all* friend requests. If it turns out they don't like what the person is saying or doing, they "unfriend" them later. But the default is to accept *all* requests. This is not how older people do it, and it's not how you would expect them to treat an online relationship, but it's how it works.

That solves the troll problem in all but the worst cases (which would be the equivalent of a real-world stalker.) And even then, the worst they could do would be spam you with friend requests which you could ignore.

In fact its intrinsically not a part of the medium. Social media is about communication, not about history.

I think you haven't been following the whole GamerGate sock puppet situation very closely. Yes, it's the equivalent of real-world stalking, and there's no mechanism to deal with trolls now. In a distributed social network, you could be scrupulously upstanding with your immediate peer nodes, and be a total asshole otherwise. Once you are inside the web of trust, you're inside, and even if someone wants to not hear from you, as a peer node, your node doesn't have to run unadulterated software; it can imply graph relationships that don't exist outside their rogue node.

This is, in fact, precisely how the TOR network had been infiltrated by various third parties: peer-of-peer implied trust relationships.

I don't think this is a workable concept, unless you can figure out a way to (1) Stop the whole GamerGate thing in its traces, without hugely invasive surveillance to root out bad actors at their houses, and figure a way to cut out the cancers permanently and/or take criminal and/or civil action to force them to not be bad actors ("Bob is a Nazi; let's put social pressure on him to change that"/"Bob is a criminal; lets put social pressure on him to not act that way by locking him in a cell"), and (2) Figure out a way to do source verification so that if ted trusts Bob, and Alice trusts Ted, that Alice can legitimately not trust Bob without having to throw away the trust relationship with Ted.

Comment Re:Who needs a damn computer anymore? (Score 4, Funny) 202

Joking aside, I wonder why the OP is putting the number crunching in the outdoor box rather then splitting the work between an embedded system for data gathering (or whatever) and off the shelf desktop for processing.

I expect all of the number crunching is being done by an on-board AI trying to figure out how the heck to get away from the high pressure water jet...

They coat the chips in some sort of coating that insulates them.

Another idea which I like even better is to immerse the whole machine in mineral oil.

It is non-conductive. Somethings might need to be insulated against the oil like harddrives but everything else can just sit in it. From what I've gathered the entire tank of mineral oil acts like a giant heat sink to such an extent that a system like that can passively cool itself WITH overclocking.

I keep meaning to build a mineral oil cooled computer and keep chickening out.

Anyway, it has the virtue of being something you could seal and then take to the literal bottom of the ocean without worrying about a rupture.

That is pretty water proof.

Comment Re:Not sure what is going on here... but... (Score 1) 572

Fine, we'll just go back to trade secrets.

That is what we had before patients. Companies simply kept information to themselves.

And a result of that was a much lower rate technological development because information was fragmented.

Look, if I come up with something... if I create something... why shouldn't I get rewarded for that? Why would you assume you have a right to take what I create and pay me nothing? Don't you see that I can't live or make that my job if I can't get paid? And if I can't get paid doing it, then that means I have to spend most of my time doing something else and only create in my spare time for FUN. You're going to get much less out of people if you do that then if you support them so they can produce stuff all the time. What is more, you're going to make sure that big companies and organizations spend basically no time creating anything. They'll make stuff but it won't be innovative because none of their own IP will be protected unless they keep it as a trade secret which means the secrets might be in a factory machine or something but never obvious in the final product.

The illogic of your position is just so fucking obvious... how can you not see how self destructive your position is here? You're cutting your dick off and saying "why is that a problem?".... well... I don't really mind if you want to live in a society like that. That is fine by me. I just don't want to live in your society then. I'll live in a society where IP is protected and you can live in one where it isn't. And we'll just see where that goes.

Comment Wolves and coyotes in Yellowstone (Score 1) 282

Nothing really new here.

Wolves, then seen as unreservedly undesirable, were eradicated from the Yellowstone region by the early 20th century. Between then and the end of the century, coyotes got larger and started hunting in packs, taking the ecological niche that wolves had filled and pursuing larger prey.

Then (1994) we reintroduced wolves to Yellowstone.

Even in the short time since, observed coyotes have gotten smaller and started acting less like apex predators and more like the sneak and scavengers that they are in other habitats where they're threatened by the apex predators.

That's a lot fewer generations than the reported adaptation of lizards in the islands.

Comment Re:20 generations (Score 1) 282

Indeed, the availability of good food and healthcare is an important factor.

In the 1950's the average Dutch man was 1m73, presently he is about 1m81, that's 3 inches more over just two generations.

The present generation of young men ~20y/o is around 1m84.
But as with all statistics you have to check the small print, in 1970 I was drafted for the military (10% of males) and the average length of conscripts was already 1m86.

Another interesting observation is the correlation between length and education, the taller people tend to be better educated.
