Comment Re: Routing (Score 1) 99

If I surmise those projects correctly, there was a fairly important degree of central control and some kind of authority to make decisions, and the mesh networks were of limited scope. A mesh network of the size that the article presumes would be massively more complicated and would have to be able to react dynamically to outages.

The current Internet has a combination of a limited number of players for backbone and a fairly slow routing protocol that is fairly limited who gets to participate. A routing protocol that could handle something like this hypothetical mesh network would need to function a lot more like an interior routing protocol, but those only work because a single organization controls an autonomous system. To my knowledge there is no organization-to-organization routing protocol that can react with near instant speed to the changes in the network that will inevitably occur as nodes connect and disconnect from the mesh.

Routing was the first problem that came to my mind too. An unreliable network requires a fast routing protocol, but fast routing protocols are very traffic-intensive for large networks. A large wireless mesh network would spend an inordinate amount of it's bandwidth just keeping converged.

That's before dealing with security/trust issues. It's already proving a problem on slow routing protocols as the recent Russian incident shows where relatively few people have to be trusted, it would be much worse with every small player possibly being able to make adverse changes.

Comment Re: Cryptocurrencies make it plausible (Score 2) 99

Just so we understand each other...

Are you proposing that various entities pay small amounts for their little connections to larger entities with larger connections, which in-turn pay to connect to even larger entities to interconnect them all?

Isn't that what we have now? Last time I looked at traceroute results, I connected via inexpensive residential link to inexpensive residential ISP, who connected to regional ISP, who connected to backbone provider, who connected to another regional ISP, who connected to a business ISP, who connected to hosting/colocation/cloud service.

Comment Tomography (Score 1) 40

They basically took a CT scan (computed tomography) using radio waves instead of x-rays.

Tomography has been around for over 80 years. It's why there's no lens when you have a traditional x-ray taken. You just fire the RF rays in a uniform direction (in this case the single WiFi course acts as a point source with all rays radiating radially), and capture them using a flat photographic plate (or in this case, by moving the WiFi receiver around on a plane). What they're doing isn't even as sophisticated as a CT scan because without moving the RF source as well, they can't capture 3D information.

Suck it up.

No. Sucking it up is acquiescence and condoning the behavior. Work to influence others to behave better, and to show you're not like them, because unless enough people do, it will continue to affect you and yours, fair or not.
A black person who doesn't speak up against black people who behave in unacceptable ways is no better than a cop who doesn't speak up against police brutality or a white person who doesn't speak up against racism. You may not be required to, but if you don't, things will not change, and you won't garner a lot of sympathy. If you help sustain status quo, even by "sucking it up", you're part of the problem, not the solution.

Interestingly, on the other hand in porn and swinger societies, black men seem to be quite popular. There's probably a mix of the exotic and forbidden at work, as well as the fact that it's generally a safe environment with other people present.

I think it's mainly a (perceived or real) correlation between ancestry and penis size. The BBC genre has little to do with the British Broadcorping Castration.

Comment Re:Fuck California. (Score 1) 220

In this ruling, discrimination means discrimination based on a protected factors (race, religion, gender, sexual orientation etc). Landlords are free to discriminate however they want, so long as it isn't relating to those factors.

How about refusing rental to "men wearing multiple chains", "men wearing baggy pants", "women with painted fingernails exceeding 1 cm", "women wearing deaf pants", or anyone saying "dese" or uses double negations?

Didn't take long for the "internet racist" to show their ugly faces. I almost feel sorry for them.

You mean racists like folks who advocate putting quotas on how many Asians are accepted to universities and high-paying jobs because they tend to do better than whites? Affirmative action against whites I can kinda understand. The operating premise being that in the past whites obtained their power, influence, and money partially by repressing minorities. And that the aftereffects of those past transgressions still slightly influence people's positions in society, so a counter-influence is needed to level the playing field. But Asians historically were one of those repressed minorities. Applying affirmative action against them just exposes you as a racist - someone who wants other people's position in society to be determined not solely by their ability, but partially by their race according to your unsubstantiated prejudices (in this case, that all races should be equal in everything, even if they're really not).

Despite what I just wrote, I actually agree with what California is doing with Airbnb. If you browse through their listings, the vast majority of properties are listed by landlords doing short-term rentals as a business. Not homeowners renting out their home while they're on vacation. If it's the home you live in with your personal items holding great sentimental value, you can rent it out to whomever you want. If you're only comfortable with people of the same race as you being in your home, then so be it. But if it's a second (or third, or tenth) house you rent out as a business, and your only attachment to the furnishings is their cash replacement value, then anti-discrimination statues should apply.

Comment No, the reason is laws. (Score 3, Insightful) 119

There is a reason that American teenagers aren't working in orchards... if growers paid enough to get teens to take the jobs, nobody would be able to afford fruit.

No. The reason is that the laws (child labor, working conditions) make it impossible for them to use teenagers any more.

Meanwhile the illegals can't complain about working conditions - and will work for less than minimum wage in (those occupations where it applies.)

US citizens needn't apply because they can't compete. (Even if they were willing to work for sub-legal prices and/or in sub-legal conditions, the employer can't risk that they might turn around and demand the missing money or compensation for the conditions.) The illegals, meanwhile, can afford to work that cheaply because social programs can pay for much of the support of them and their families - turning programs intended to help the poor into subsidies for their employers.

Meanwhile, the government's non-enforcement of the laws against the illegals working means that, in highly competitive markets (such as construction contracting), employers are left with a Hobson's choice: Use illegal labor and be competitive, or try to use legal labor and go out of business.

I'm in a "weird" part of the country without much in the way of migrant workers and Americans do all "the jobs Americans won't do".

A friend of mine has a teenage son who's worked at a nearby orchard for a couple years, after school and summers. I know, he can't exist according to labor economists who don't get that bottom-wage jobs are for kids with no experience. He's off to college next year, and I doubt a robot will be taking his job.
