Comment Re:Hard to feel bad for them (Score 2) 687

Anyone in sales learns early on that they should dress well. They need to look attractive. The concept of a Booth Babe is to look attractive and successful. But the question we should all ask is "To Whom?"

A typical Slashdot nerd wants answers, not pretty looks. Most are indifferent to Booth Babes. In other words, when selling to a technical crowd, Booth Babes don't help much. If anything, they can intimidate an asexual nerd from visiting (I have worked with people like this). Most nerds would be more impressed with large kinetic displays.

I disagree with the notion that Engineers and IT have a culture that encourages Booth Babes. The Booth Babes are selling to Managers, not Engineers. The question we all should ask is why Management of technical fields like this are falling for this kind of stuff.

In fairness to those who practice the law: I've seen first hand what happens to those who stop practicing the technical arts. Those skills atrophy pretty quickly. My own brother has a Master's degree in Mechanical Engineering and really was a true "Rocket Scientist" in the 1980s and early 1990s. He's now a patent attorney. Much of what he knew as an engineer is long forgotten.

Likewise, I have little doubt that those who stop practicing the law quickly lose track of all the handy exceptions, loopholes, and interpretive subtleties of the law.

There is no shame in admitting that one does not understand the subtleties of surveying, and determining flood plains. What is shameful is when someone with only a meager background goes off and tries to write legislation with little input from those who would be bound by such legislation.

Let the Engineers explain the proposal, and let the lawyers enshrine it in to law. We all have to read and understand this stuff, or the law will be of no use to society. Without comprehensible and reasonable legislation, we would then have a very jaundiced view of the very fabric that is supposed to keep our society fair and productive.

An Engineer is obligated to build a reliable, workable design. If the state tells the profession that the Earth is flat, they'll still design around a spherical Earth. They'll find some other sophistry to justify it.

At the end of the day, who is going to sue an engineer for suggesting a slightly more resilient design? I see estimates of 100 year floodplains that I know from visiting the site are utter nonsense. Careful review of flood-plane location is always a good idea during the initial site survey. It is almost never a good idea to simply take someone's word for it.

This bill seeks to do for the state what should be done through Engineering guidelines.

A sea-level rise estimate would have to take in to consideration all sorts of issues, not the least of which is potential for Tsunamis, Storm surges, and the like.

Sadly the FCC has not been doing much oversight or even decent regulation for a good many decades. I've been following it off and on since the late 1970s. They were a mess back then, and they're still a mess. This is what happens when technical people leave judges, lawyers, and politicians to fend for themselves.

I don't think we're disagreeing much, but I am going to point out that even in a very practical sense, bandwidth costs money. You focused upon the physical fiber infrastructure, whereas I focused on the concept.

In a practical sense it costs money to get the hardware to support that connection to the home. It costs money to modulate it on a cable to the end user. It costs money to trunk and coordinate the flow so that we do not need to overbuild infrastructure. The Terrabit link you cited may be very low in power, but the gear to process that link at each end is not.

After all, you don't have a pair of wires that go all the way back to the generation plant. You have wires that go to a pole transformer that goes to a substation on a transmission ring through very large transformers, breakers, relays, and so forth. THEN you get to one of several generation plants.

Data networks are no different.

Do we need to regulate these monopolies? Of course! Do we need to set minimum performance standards? Of course! Do we need to set privacy laws? Yes, of course!

This all costs money. My question to you: The infrastructure is expensive. Who pays for it?

I work for a large industrial user of electricity. We have medium voltage substations and we buy our electricity by bidding for blocks of energy in advance and by buying it off of the spot market from the PJM grid. We do get good prices. Why? because we own some of the infrastructure and we attach at the inner tiers of the grid. If you could afford to put a large substation in your back-yard and to run feeders to the transmission grid at a million dollars per mile, you too could get these rates.

Likewise, if you build a data center in your basement, and you manage your bandwidth, you will be paying a lower rate than someone with a home firewall/switch who just wants an ISP to handle his e-mail, DNS, and web site for him.

But you will still be paying for the bandwidth. Someone needs to make the connection in to the rest of the Internet. Someone eventually has to attach to the inner Tiers of Internet routing. That infrastructure isn't free either. The hardware and the trunks and the energy that hardware uses isn't free.

So there will be graduated pricing and volume pricing for how you use bandwidth. Eventually, I predict time-of-day pricing for bandwidth use.

It's not that outrageous. Look at bandwidth use on the Internet. It is not constant. It has a rhythm and flow just like most energy firms have diurnal curves of consumption.

What the FCC seeks to do is to set up a framework that acknowledges this reality. I don't like it, but I also realize that it is very necessary.

It happens all the time with utilities. People fail to notice that their toilet flapper valve is leaking until they get their next quarterly bill. And it will be a very large bill.

The same happens when someone fails to realize that the compressor for their heat pump is running nearly all the time and isn't keeping up with demand.

Most utilities have forgiveness policies for people who simply can not know any better. An example would be a deaf person who has a toilet flapper valve problem. He or she would never hear the water running.

Likewise, a busy single parent with kids and several computers could also have this happen. Computer hygiene is not always easy.

Uh, no. The differences aren't so huge after all.

The cost of GENERATING electricity is actually pretty small. The cost of getting it to your home is significant. Furthermore, fundamental laws of physics would tell you that the cost of higher data rates is more power. Literally. So at some fundamental level, this is not a bad idea.

However we need to recognize some facts: the delivery company of this content is a monopoly. The infrastructure to deliver FiOS was paid for and is maintained exclusively by Verizon. So, as a monopoly, they should not be allowed to "shape" traffic, they should not be allowed to block traffic, or even to inspect it without a court order. But it is not unrealistic for them to meter how much traffic is headed to your home and to bill you accordingly.

This will cause two things to happen: First, people will become somewhat aware of how much bandwidth they're using and what they're getting for that bandwidth. You want to play games at high bandwidth? Have at it. But expect to pay for it at the end of the month, just as someone who keeps their thermostat real cool in the summer and very warm in the winter will pay for it.

Comment 12 Volts? (Score 2) 237

Why 12 volts? Telephone companies figured out decades ago that 48 volt positive ground systems were more desirable. They reduced the need for heavier copper wire, and they are not likely to be lethal shock hazards (though burns are certainly possible).

Furthermore, every motherboard has multiple switching supplies built in. We have 12 volts, 5 volts, 3.3 volts, 1.8 volts, and probably some adjustable voltages too. Some even have separate regulators for individual parts of the board. We will never be rid of the power supplies. We have simply moved them closer to the processors, memory, I/O, and GPU. Why not design the boards to use -48 volt battery systems as primary inputs so that we can reduce corrosion, use existing infrastructure designs, and keep I^2R losses down?

Comment Water Utility View (Score 1) 267

If all we do is watch documentaries and read Wikipedia, this won't be much of a debate.

Nearly all raw water we get from wells and from surface flows (rivers, streams, etc) is dirty. We use energy to clean it up enough to be fit for human consumption.

That energy has to come from somewhere. The question with Fracking is whether the additional contamination it puts in to the water supply is too expensive to remove. It may be so expensive that the value of the gas we'd extract makes the process uneconomical. One thing we do need to consider is some way of linking these two activities so that whatever additional costs are incurred for water clean-up are paid for by the drilling operations.

To know that, we need better information. We need before and after comparison data. That data is just now emerging. I am hopeful that after all is accounted for, the costs will be favorable for Fracking.

First, it is a 24 GHz system. Anything much above 11 GHz is going to have rain-fade problems. We have had years of experience with 24 GHz systems. Even though these links are less than 2 km and have very significant fade margins, we still lose them during any significant rainfall. The reliability of a 13 km link will be frustratingly poor. Been there, done that.

Second, as the AC points out, the cost is not the unit itself. The cost is in the installation and grounding. The structure you put this thing on will be struck by lightning. The only question is one of probability.

Third, though the costs are high, remember, nobody can interrupt a microwave signal while digging on the side of the road. Microwave networks may not be cheap, but after taking all expenses in to account, you may find that it can be a very good fit if you have lots of land to traverse, no roads or rights of way to get you there, and want to stay out of a common carrier.
