Comment In Dutch it's endemic now, too (Score 2) 284

Shakes cane, "when I was a boy", etc....

In Dutch, this has become the thing people do now as well. Being a Germanic sister language of German, Dutch also does/should not use the apostrophe in this sense, but people do it anyway. Then again, a language is a living thing, and in the end, it is what people speak and write. I can live with this.

Yes, and no. Yes, if you work off the model where there is a universal "now", and light just happens to travel at some high speed. In that model, the explosion happened, and we are now just waiting for the light to finally arrive. However, the problem with that model is that there is no universal "now".

So no: The speed of light is not related to light. Light travels at that speed, but there is nothing about the properties of light that somehow determines that speed; other things, such as gravitational interactions, travel at that speed as well. That speed is not just some arbitrary speed limit, but rather the speed of causality, full stop. There is nothing at point A that can even influence point B in less time. This is what determines our past light cone, or rather, our past causality cone.

And to be clear: this star's bright light-up is not in our past light cone, and so, for us, it did not yet happen.

The fact that we nowadays have these launches and first-stage landings as a matter of course, with little mention outside of technically-minded news sources, is in fact a great achievement. This is exactly what space travel should become.

You can be on the tower, or you can be on the ground, but you can't be on both. It's not the potential that kills, it's becoming a circuit path. Birds roosting on power distribution lines, which as a general rule are not insulated, don't die due to that fact.

That's not how any of this works.
  First, the tower is grounded and at the same potential as earth. The primary concern is not electric shock.
The parent poster was concerned with worker safety when exposed to radio frequency energy.
https://transition.fcc.gov/Bur...

After performing the required calculations and determining it is safe to work at x distance from the transmitter antenna, workers will typically wear a personal RF monitor to measure exposure.

As others have mentioned, you are pretty wrong here. The vast majority of AM towers are the radiators and the ground is the ground plane. Between them sits a huge isolator which is generally ceramic. If you stand on the ground and touch the tower above the isolator you will get burned or dead.

This makes colocating on an AM tower a PITA as you can't just run a conductor up the tower without a transformer. There are ways to do it, my favorite being to get power off of the tower lighting circuit to power a tower mounted enclosure and then running fiber off of the tower if I need to come off of it.

1. Required to do free peering.

With anyone? No conditions? The devil is in the details. I need some justification. Do my customers want to get to your content above a level where it makes sense for me to peer with you? Do you run a decent network that isn't oversubscribed? Lets say $content provider traffic over your network is crap, lots of jitter, loss, whatever. I can also get $content providers traffic from someone else. If my customers use a lot of $content providers service, then I'm not peering with you. My customers don't know or give a crap. They just know that their Netflix is crappy and its my fault.

2. Must provide, among other services, a basic FCC specified service at a set price with a fixed installation fee. Initially 1Mbps up/down for $10 a month with a $50 installation fee.

This would kill my company and any start up ISP. Your mile drop up to you house in the hills might cost me 5K to build. I'm not signing up for that. I can't build out anything for $10 per month. Not signing up for that.

3. Legally obliged to provide service within two weeks of any request in their designated service area, or face fines.

This would kill my company and any start up ISP. How on earth am I supposed to build fiber out to you in two weeks? How am I supposed to build out infrastructure to hit every house in an area with fixed wireless? Completely impossible.

3.1 Local governments specifically allowed by FCC to provide service to customers not any active ISP's service area. 4. Must tier service only by bandwidth and nothing else.

No real issue with the former, but the latter would preclude SLAs for business customers, DIA vs Best effort, i.e GPON vs Active fiber so I think your restriction is dumb and not well though out.

4.1. No data caps or overages. Throttling only allowed to temporarily deal with network congestion and must not lead to worse service than the basic FCC mandated plan.

Not the end of the world, but also would preclude a lot of smaller rural WISPs from ever starting. You have to have over subscription if you want residential pricing that isn't measured in thousands. Thats just how the internet works. With over subscription comes the requirement that you implement a fair queue method. That might be caps, overages, or throttling.

5. Must not filter any traffic except for security purposes, and those filters should be under the control of the customer.

I'm mostly ok with this.

6. Must allow customer to provide their own equipment, without additional charges.

This doesn't always work. I mean if you wan't to buy your own Calix 844G then I'm fine with it, it saves me $300+, but I need to control the RG side of it. You can't just expect that I'm going to put the resources into making your $whatever GPON device work. There are a ton of innovative deployment scenarios that just don't work that way. Take some of the Open Cord CPE implementations where the brains of the CPE exist in the data center. Your Idea just wouldn't work.

That being said, I feel strongly that ISPs are common carriers and should be regulated under something like Title II, abet with forbearance from a lot of the more onerous crap that doesn't really apply to us. Forbearance run by a bunch of people like you, or the current fcc, that have no idea what the internet is or how it works is a blade hanging over the neck of ISPs so it scares me. Things as they were under the open internet order worked pretty well, but there was always that blade hanging there and you never know who is going to have their hands on the lever. We do need a re-write of the communications act creating something like Title II for ISPs.

Comment Re:'10 times more efficient' and xenon gas (Score 4, Insightful) 52

It's all about delta-v, not about the occurence of said gasses on Earth.

Rockets work, whether we like it our not, according to the Tsiolkovsky rocket equation: the delta-v you can obtain it only logarithmic in your start mass / payload fraction, but linear in your exhaust velocity. That velocity is in ~3 km/s for chemical rockets, but 20-50 km/s for ion engines. That allows you to push a probe/ship from LEO into a transfer orbit using a massively lighter ship, which in turn allow you to launch that into orbit using a massively smaller launch vehicle.

Comment In Switzerland, they pretty much have to, by law (Score 5, Interesting) 545

In Switzerland (at least in my home Canton of Zurich), the children's way to school ("Schulweg") is pretty much sacred: Walking to school alone teaches the children to deal with the world around them, and it builds confidence. During the first year of Kindergarten you can bring them, but then they go alone.

When children live too far away from school, there is a bus service, but they make a point of letting the children off the bus some 1000ft from school, so that they still have their "Schulweg."

Comment Today's business class is the 70s' economy class (Score 5, Interesting) 819

Judging by images like these, today's business class is pretty much what economy class used to be in the 70s. Some argue that flying has become too cheap. I beg to disagree: flying in a humane manner has not become cheaper, it's just that you'd have to book business class nowadays.
