  1. Re:No surprise on Energy Prices Skyrocket in South Australia (yahoo.com) · · Score: 1

    Generally no, the consumer never sees this price. The price-per-MW is going to be for transmission system exchanges ("power highway"), instead of distribution system customers ("local streets"). Odds are that the customers will see their bills go up in a month or two, as the power company exercises clauses in their utility contracts to 'cover their costs'.

    In practice, it heavily depends on the customer's billing schedule. Here in Portland, OR, I have a fixed residential rate. Some companies, such as Pacific Gas & Electric (CA), Southern California Edison, and Hawaiian Electric, use (optional?) time-of-use (TOU) pricing, where the residential prices are higher during 'peak hours', when everyone is getting ready for work, or returning home and turning on their televisions. These TOU programs often have "if it didn't save you money, we'll bill you the fixed per-kWh rate" options. Real-time pricing for residential customers has been tested a few times, but hasn't been rolled out, for both technical and programmatic reasons.

  2. No surprise on Energy Prices Skyrocket in South Australia (yahoo.com) · · Score: 1

    This is actually perfectly normal behavior from real-time priced power markets. There's a certain point where the consumers are going to become non-responsive (you'll pay $1000/MWh if it's 90 degF in your house as the sun is setting) and that non-responsive load exceed the available generation. There needs to be enough dispatch-able generation (like the gas generator in the article) to cover all of the non-responsive load, or you get "market failures" like this, where the effective spot price climbs to infinity.

  3. Yes, it's okay on Ask Slashdot: Is It Ever OK To Quit Without Giving Notice? · · Score: 1

    There are cases where it's okay to up and leave, yes. Management may want two weeks to wrap up loose ends, but it's just a matter of 'being polite' or 'being professional'. Yes, your references will suffer.

    On the other hand, it's remarkably rare for employers to offer the same two weeks when they want you to be out the door, ranging from "there are free cookies in the lobby" to "this isn't working and you're done on Friday". So it's really a matter of turnabout being fair play.

  4. Insanity on To Encourage Biking, Lose the Helmets · · Score: 1

    Ultimately it should be a personal choice, but there's an element of wisdom in wearing a helmet.

    I've been in two bike accidents (and am not yet 30), both times seemingly random faceplants at low speed. The first one was with a helmet, and I looked pretty banged up for it. The second was without a helmet, and required stitches.

    Helmets are that ounce of prevention, and while bicycle accidents are statistically less fatal than car accidents, safety measures are still a very good idea.

    Except in Texas. ERCOT can set some pretty funky rules by not having to worry about interstate commerce.

  6. Load contracts on Microsoft Pollutes To Avoid Fines · · Score: 2

    The fact that it's M$, as mentioned above, is a fluke. Large power consumers will enter into contracts that say 'we will use Xm to XM power annually with S loadshape, will not consume more than L peak power at once, and will throttle our power use up or down if asked to N times a year fo D days.'

    Deals like this help optimize generation and keeps the grid balanced. Unlike in SimCity, you can't just plop down a stack of generators and wait for load to catch up with it, the generators have to output at a fixed 50/60hz (+/- a little). Like a truck engine, the fuel required to keep a particular speed is dependent on the load at any one time. Forecasting this load then becomes an issue that a *lot* of utilities put time, money, and effort into, so that they can ramp up or down as needed, keep to their own contracts of power quality and quantity, and efficiently use the generators they have. It's not like they're happy about selling less power when the loan payments on the multimillion US$ generator comes up each month.

    The power customer with simply taking the more contractually prudent course of action ~ spending $70k, rather than spending $210k. The fine is as much to cover the fuel burned on generators that were left spinning for the customer as to thwack them upside the head about contracts.

    There hasn't been any mention of the tactical response times offered by a carrier. Sure, a country can launch ICBMs and strategic long-range bombers for long-range offense, but having a floating city twenty minutes out from the operational theater changes the game a fair bit.

    In the rarely employed non-combat roles, there's again the benefit of having however many tens of thousands of tons of ship and resources at your disposal on-site.

    In general, the *USA* laws say that you can legally photograph anything visible from public property that does not require "specialized equipment", and anything on public property. You cannot legally take photographs of places where people have a reasonable expectation of privacy, including in restrooms, within private dwellings, and underneath clothing. Exceptions exist, but the law is far less restrictive than social norms are about photography.

    The UK laws imply that you have the right to apply lubricant, if you brought it, before they violate your rights.

    IANAL, but I have fun with a DSLR, and educate myself on what I legally can or can't do with it.

    In the parking lot, the most the guard has the rights to do is to ask you to leave, and to escort you off the property. The police can escort you off the property, should a representative ask you to leave. Confiscation of cameras in the US is theft.

    The problem is that you have to be defined as a "data access provider" to have the protections of a data access provider. Netting that definition requires you to play by whatever the written rules are, both in the law books and within your contract with your ISP. It's not so much a question of if I think I should be held responsible if someone else is speeding in my car, it's an issue of how the laws are written and how my insurance policy is written. Lawyers have this funny stance that "it's not real until it's in writing" ... similarly, you'll be held responsible for what you've presumably read and signed your name to in agreement.

    Yeah, sure, socially responsible thing to do. I'm not putting down $60/month and minding a wireless router just so that the neighbors can get free wireless Internet access on my dime, TYVM. Last time I checked, there were also a few clauses that basically say that you may not pretend to be an ISP, resell bandwidth, or sublet bandwidth, should you be a Verizon/Charter/Clearwire/whoever Internet subscriber. That reads to me that if you do try to use a 'all the protections of an ISP' claim, your ISP will say 'no, WE'RE the ISP' and cut you off. Nice try EFF, but it's not going to fly.

  25. Re:what's really going on? on Why Science Is a Lousy Career Choice · · Score: 1

    Awful lot of meat in your post. Can't say much during a lunch-break post, but I'll observe that there are a few billion dollars in the USG's ARRA grants, aimed at increasing T+D energy efficiency and improving renewable energy integration. There's a remarkable degree of value in 'making something'. I've made 'fantasy stock' decisions based on whether or not a given company had a tangible product, and I wish I had a bit of money to throw at those decisions at times. Such decisions directly chase the idea of strategic value in certain industries, mainly in energy and material security. See last quarter's rare earth metal 'panic', and speculate on what airlines are doing in the oil markets to cover their fuel supplies. See the massive US export of 'high technology', especially arms sales (tanks, jets, radar, and other military-sized toys ~ I love the DOD's research budgets). Heck, see farm subsidies. The curious problem with capitalism is that it relies on there being disparity between the value of someone's work and the price they're willing to be paid for it. Eventually all the money winds up in the hands of the few who are paying for the work of many others', with only an increased disparity from the top to the bottom. If the 'top' isn't spending that money, preferably in a fashion that does not net returns, Bad Things happen to capitalism.
