Comment The laws of physics greatly restrict bandwidth (Score 2) 62

A very large mesh network *used* to be possible. Not so much anymore.

> There is nothing in the rules of mathematics or laws of physics that prevents such a system.

In fact there the laws of physics DO put some serious limitations on it, especially a true mesh network. In a nutshell, the frequencies that carry over distance and through walls have limited bandwidth, which must be shared by *everyone* who wants to use any kind of wireless communication. Frequencies above 10 Ghz have a lot of bandwidth, but don't go through drywall. Also of course high frequency waves have high energy - think microwave oven.

Mesh networks are horribly inefficient in how they use the limited bandwidth available in desirable frequency bands. You can do much, much better if you have local transmitters around 1 Ghz communicating with local towers which form a backbone connected via high power dishes, or better yet fiber optics. There is a lot more usable bandwidth to go around using the backbone topology rather than wasting most of the bandwidth by using a mesh. That brings up the issue of who owns and controls the backbones.

Given the physics of it all, back in 1990 you could have built a mesh network to replace the wired connections of the day - 48Kbps max bandwidth, with each person using it an hour or two per day, on average. On a new network built today, you'd want 100,000 to 10,000,000 Kbps, with each person using it ten hours per day. So roughly 40,000 times as much total bandwidth. Not going to happen. Not with the physics we know in this century.

There *is* a way we can 40,000 times as much bandwidth as we had in the the 1990s, though. We actually have such a system working in much of Texas. It involves setting the greedy corporate ISPs up in a situation where to make money, they have to compete with other greedy corporate ISPs. Customers choose the best one, so an ISP can't make money if they suck. It's not a perfect system, but it beats the hell out of what I hear people on the coasts complaining about - a single monopoly ISP protected by a government franchise, an ISP that sucks but they don't care because nobody is allowed to offer competing service.

Imagine people with your colour eyes statistically committed more crimes.

ok I am now imagining that the hazel eye gene is significantly correlated with crime statistics.

You try your best to be a good person, to better yourself, to get on in life... But doors keep slamming in your face.

Smart people slamming those doors. I havent forgotten about the statistical significance yet, have you? Lets see.

You apply for jobs you are well qualified for, but don't even get an interview. Eventually you find somewhere but they want to pay you less than your graduate friends. And you can't take it anyway, because no one will rent to you.

If nobody will rent to me, then that statistical significance must be really significant. Hazel eyed people are apparently the scourge of the earth in the world you have me imagining.

Would you accept that as fair...


or would you want the law changed to stop it?


Did you realize that a false dichotomy doesnt make your point?
Did you realize that you clearly forgot about the statical significance aspect of the whole thing?

Rational people act on statistical significance. Rational people can also make an argument without resorting to a logical fallacy.

What would you do at that moment?

Life isn't always fair. Deal with it.

Beyond the narrative here, this is government thugs interfering with things for their own personal benefit. You know whats better than Hotel lobbyists giving you free shit so that you go after AirBnB? Better than that is forcing AirBnB into the lobbyist game at the same time.

You should be talking about the oppressive zoning laws throughout much of California, but you are talking about fairness while painting a clever picture that attempts to provoke empathy, and you punctuate that story-time by invoking a logical fallacy, and that fallacy itself is strongly suggesting that you think that people should be forced by government to do the opposite of what a rational person would do, which is to pay close attention to statistically significant data and act in accordance with it.

Comment Re:Racists or nazis? (Score 1) 212

The nazis used to have book burnings, and the situation at Berkeley sounds a lot like what the nazis used to do in the beginning.

The NAZI's raised an entire generation in preparation.

They infiltrated the schools first. Hitler formed Jungsturm and Stabswache in the early 1920's. The former blossoming into the "Hitler Youth", the later into their "S.S."

Fascism comes from the left because it starts in the schools.

If you browse through their listings, the vast majority of properties are listed by landlords doing short-term rentals as a business.

Lets accept this as a fact.

So what? Why even mention it?

What you are doing now it getting involved in those landlords personal business. If you wouldnt fuck with a single mom waitress that is renting out a room for a little extra money, then you also shouldn't fuck with people that do it as their primary income.

Because legislators said so.

You just state that like it's an obvious fact, but compared to "the sky is blue" it does not immediately follow.

I dont know how obvious it is, but I've known it my whole life. I knew it when I was 6 years old, so its the kind of thing even a 6 year old learns.

Please explain to us why (a) you dont know what I knew at 6 years old, (b) you are demanding that this knowledge be "obvious" before you will accept it.

Comment Re:Illegal labor (Score 4, Interesting) 119

Here's what happened up here in Canada. In the late 1980's you could pick fruit/veggies/tobacco/etc and earn enough money to put you through a year of university, if you got on a good farm you could earn enough to put you through 2-3 years. This was still the norm in the early 90's, by say '94ish there was a great push of factory farms. And suddenly there were people saying "oh we can't afford to pay these people those wages." And suddenly they loosened the wage rate, and more followed suit. It went from hourly to bushel, and then you started hearing the "but people won't work for what we're paying!" So they relaxed the hiring regs, and allowed the importing of 3rd world labor to do those jobs. And the wages still fell.

If you want to fix the problem, the laws have to be changed. Most governments have no interest in changing the laws on this, and now it's the norm. Now people are seeing this with the abuse of H1B's in the US, and here in Canada with TFW's. The difference between the two is a TFW can be used in any job. The current area we're seeing a flood of people in is with business cleaning run by fly-by-night shops that hire people who are illegally in Canada. But businesses from the CIBC(big bank up here) replacing workers with TFW's, to skilled trades in the oil patch have been hit.

Comment Using it wrong (there are many options) (Score 1) 35

Unlike most protocols, rsync has a built-in checksum, actually many, many checksums, so it's much more reliable than just about any other protocol. It checksums every few kilobytes.

We backup many terabytes every day and we periodically verify the backups with Sha-2 hashes. I've never found corruption due to rsync. On the other hand, rsync *is* very flexible and there are many options. It's certainly possible to use a set of options that doesn't give you what you want.

Also, if you're backing up live systems, especially databases, using any method, you have to take care that the data doesn't change while your backing it up. That applies to any method of backup. For mysql, see man mysqldump, then back up the dumped files.

Comment SSH is the *right* way to do rsync. Rsync protocol (Score 1) 35

Using ssh transport instead of the native rsync protocol, which is unencrypted, is the *right* way to do remote rsync with sensitive data. Much like tunneling http over tls is the right way to do http for sensitive data.

You can also do the rsync network protocol bare, using a rsync:// url. That's the wrong way for sensitive data, and the way this developer chose to do it.

Comment Re:Childbirth? (Score 1) 280

Studies have repeatedly shown that children who spend all day in childcare while both parents are working have greater behavioral issues and more learning issues than children where one parent stays home. It does not appear to matter which parent stays home, although I suspect that the sample size where the father stays home is too small to be conclusive.
