The Ambitions and Challenges of Mesh Networks and the Local Internet Movement 54

Lashdots writes: Two artists in New York are hatching a plan to teach kids about the internet by building their own. They'll be creating a small, decentralized network, similar to a mesh network, to access other computers, and they'll be developing their own simple social network to communicate with other people. It's part of a growing movement to supplement the Internet with resilient, local alternatives. "And yet, while the decentralized, ad hoc network architecture appeals philosophically to tech-savvy users fed up with monopolistic ISPs, nobody’s found a way to make mesh networks work easily and efficiently enough to replace home Internet connections. Built more for resiliency than for speed, each participating router must continuously search for the best paths to far-flung machines. For now, that makes them of limited interest to many ordinary consumers who simply want to check their email and watch movies."

I really do not understand the hate involved here. Let's assume that climate change is NOT happening. We still have the following facts:

1) Fossil fuels are a limited supply. Maybe enough for another 50 years. Maybe 100. But still limited.

2) We purchase large amounts of oil from countries that, in general, do not like us.

3) If it were not for oil, our interest in the middle east would decline greatly, which would be a good thing. If Muslims want to kill Muslims, that sounds like their problem. There is no "right" side in a conflict like that.

For all of these reasons, we should be decreasing our dependency on fossil fuels. More fuel efficiency and alternative fuels just simply make long term sense, even without considering climate change.

So, what is the problem?

Comment: Large Tesla battery quite useful (Score 1) 333

by John Bayko (#49570999) Attached to: Why Our Antiquated Power Grid Needs Battery Storage

Having a large house battery has other uses, such as for power outages. But consider this: an electric car has a huge battery capacity, but can charge from mains at only a trickle. That's okay for a commuter where you charge overnight, but if you have heavy use (say, a moving weekend) you need to charge it faster. Having a battery that has a rapid charging connection to the car (like the stand-alone chargers) fixes that problem - park for half an hour, and you're ready to go with almost a full charge.

Before everyone gets upset about data collection: This Supreme Court case is not about Spokeo's data collection. It is about who has the right to sue and under what circumstances. Even if the Supreme Court rules in favor of this individual, all it means is that the individual can continue their suit. It is not a ruling for or against Spokeo's data.

According to John Oliver most people think Edward Snowden is Julian Assange. Oliver did "man-on-the-street" style interviews in New York, asking people who Snowden was. Most people, if they knew the name at all, thought he was "the guy who sold government secrets to Wikileaks."

The report doesn't mention this at all, so I'm not sure what to make of the statistics. If you asked people "Which color is brighter: green or brown" but they had never heard of brown before, you wouldn't be able to draw many meaningful conclusions from it. The report itself doesn't even mention what questions they asked people. There's really just no information here at all.

Electric vehicles have lower maintenance cost as gas vehicles. Hybrid vehicles have the same maintenance cost as gas vehicles.

I was under the false impression that hybrids also had lower maintenance, because of things like regenerative braking. The second article points out that as an advantage, but says it is offset by other things.

You do know that some SUVs have room for more people and/or more cargo, right? I have five kids (three are adopted, before you start whining about overpopulating the planet). Try finding a car that will hold seven people. Some SUVs have third row seating. How about people who want to actually go off-road? Should they drive a Prius so that they need to be towed out of the woods? How about people who have to haul trailers.

In short, you are either short-sighted, or a troll, or both.

The summary says that Wikipedia does not have a mobile site. That isn't true. The BBC article linked from TFA actually says:

Sections of sites owned by the European Union, the BBC and Wikipedia currently fail the search giant's Mobile Friendly Test developer tool.

I just tested the Wikipedia mobile site with their tool and it says "Awesome! This page is mobile-friendly." However, if you feed it wikipedia.org instead of en.m.wikipedia.org it complains that the links are too close together, which is definitely not the case. Even the picture it shows of "How Googlebot sees the page" is quite clear.

Weekend, where are you?
