Comment Re:where is your brain? (Score 1) 39

Are you actually asserting that demand is level 24 hours a day?

It can come very close.

In California, for example, a very large part of the demand is pumping water through aquaducts. By placing reservoirs along the way and doing most of the pumping during times of low electrical demand, California electrical utilities used to be able to keep the power demand nearly constant - and can still keep it much more level than in many other places.

Also: Coal plants can provide baseload, while wind and solar together do a great job of shaving peaks: Higher wind corresponds to higher HVAC load as well as higher generation. Solar not only tracks the air conditioning requirements but also comes close to tracking the daily load peaking - and solar plus wind tracks it even better, since the lake effect makes an afternoon-through-evening hump in wind generation.

at a power output proportional to the CUBE of the windspeed.

is this relevant somehow?

Yes, very. The steeply up-bending curve means that wind generators that are able to make use of high winds - which only happen for a tiny fraction of the time - have a peak power rating far above the average power they are able to produce in normal winds. So the peak power vastly overstates their average contribution.

The power can be stored,

The issue is not that the power can be stored.

The issue is that power capacity comparisons overstate the total amount of energy you get out of the renewable generation equipment over the long haul because coal generation can run near capacity all the time and renewables (excluding water power) only a small part of the time.

I'm quite supportive of renewable energy. (I'm a major participant on one of the renewable energy tech discussion boards, too.) But while it's very GOOD that renewable power has passed coal in power capacity, even with near-ideal load-levelling storage, it will take about another factor of three before it surpasses coal in providing usable energy to the loads.

... they overtake coal for amount generated per unit time.

Renewables may have higher total peak, but coal plants have level output and can run 24/7, while sun is only about a third of the day and wind varies with the weather - at a power output proportional to the CUBE of the windspeed.

1. Very few of the emails are DKIM signed. Check for yourself.
2. Even where DKIM is signed, it relies on the following assumtions.
A: The attacker has not compromised the Google private key
B: The attacker has not compromised DKIM or any of the technologies it relies on
C: The attacker had not compromised the sending account at the time of sending.

The requirement of assumption C is applicable regardless of who the attacker is. Assumptions A and B fail when considering a highly motivated state actor. It should go without saying that everyone here knows that major powers actively work on things like A & B, and C is their bread and butter.

Do I think that a power like, say, Russia, has compromised DKIM itself, or any of the technologies it relies on? Probably not, but I certainly wouldn't put it past them. Do I think that said entity has compromised the Google private key? Probably not, but again, I certainly wouldn't put it past them. I absolutely would not put C past them - but it depends on the importance attached to the topic at hand.

To reiterate: the majority of the leak will be real. But there is an active, demonstrable history this cycle, of the attackers salting the leaks with fakes, using the real content to try to legitimize the fakes, so try not to be naive about all this.

Right. So let's take a look at how this "excerpt the gotcha" plays into that.

Slashdot writes about Zuckerberg:

a later exchange between Sandberg and Podesta showed that Mark Zuckerberg was looking to get in on the action a bit, and perhaps curry favor with Podesta and the Clinton camp in shaping public policy.

Except that the email from Shelly about Zuckerberg very clearly begins:

Mark is meeting with people to learn more about next steps for his philanthropy and social action and it’s hard to imagine someone better placed or more experienced than you to help him. He’s begun to think about whether/how he might want to shape advocacy efforts to support his philanthropic priorities and is particularly interested in meeting people who could help him understand how to move the needle on the specific public policy issues he cares most about

Likewise on the other email from Cheryl. They mention the "She came over and was magical with my kids" re. Clinton. They don't bother mentioning the reason for Hillary's visit, which can be seen in what she's replying to:

To: Sheryl Sandberg
Subject: At a loss for words

Can't imagine your pain, but know that you are surrounded by people who love you. Mary and I are praying for you, the kids and, in our Catholic way also for Dave.

... and the part before the excerpt:

Thank you – means a lot to me that you reached out.

And I like that you are praying for Dave. I have to believe in heaven now.

This wasn't some buddy-buddy campaign visit, this was a "person I know's husband just died" visit. Likewise, the implication that they're supposed to give here is that they know her because of Facebook. No bothering to mention that the reason that they actually know her is because she was Larry Summers' Chief of Staff during the Clinton administration.

Almost anything can be made to look sinister when you take it completely out of context. Which is the whole purpose of these emails.

Furthermore, do you honestly think you couldn't do the exact same thing by picking through the Trump campaign's internal messaging? Do you have any clue how many people of note a major campaign interacts with, how many people work for them, etc? We know given Trumps record on server security that hacking him would have been a breeze, but miraculously nobody bothered. Why do you think that is?

Lastly: take everything you read with a grain of salt. I know everyone's reaction to statements that emails could have been altered (and scattered amongst real ones) is going to be "You just don't want to discuss them!" No, the reason you should take things with a grain of salt is that the other anti-Clinton hacks this year have done exactly that. Leaks posted by the hackers in different places involved cases where they had involved changing the same file to say different things (such as a donation list where they added a donation from Soros to a Russian democracy activist, but had different values for the donation in different versions of their release), cases where files were dated to after the hack occurred, and cases where file metadata showed the changes they'd been making. Salting real data with fake is something that they've been doing this year, so it'd be naive to think that they're just going to stop doing it now. Come on, even the most die-hard Clinton hater is going to be hard pressed to actually believe that the Clinton Foundation has a directory sitting around literally called "Pay for Play".

Yes, the majority will be real. But don't be naive when viewing them and assume that you can just take everything at face value.

Because we hate Wall Street, let's instead put a billionaire real estate scammer whose entire adult life has been spent trying to kiss up to investors and banks to get loans for his businesses, and who refuses to reveal what banks he's in debt to in power.

Because we oppose the Libyan conflict, let's put in power someone who wants to bomb the children of terrorists, insists that waterboarding isn't harsh enough, wants more nations to have nuclear weapons, wants to build a new generation of nuclear weapons, and spent his first security briefing repeatedly asking why we're bothering to have nuclear weapons if we're not going to use them.

Because we oppose free trade, let's put in power someone who spent his entire career - up until he decided to rebrand himself as a populist for this election - championing free trade, built his empire on dumped steel and undocumented workers, and - until it was shut down as a scam - championed the benefits of outsourcing on his Trump University page.

I'm not even sure where you're getting that Clinton has been big "drill baby drill" champion, but Trump has literally called for "drill baby drill" in speeches, including lifting all federal restrictions on offshore drilling and elimination of the EPA.

So if you want to cut off your nose to spite your face, go right ahead, but please understand why many people will not be joining at you.

And if your argument is "I'm not supporting either of them" - if you don't vote for one, you're supporting the other. Not to the degree of voting directly for the other, but you're still supporting them. Because that's the way the US electoral system works.

Submission + - Google Chrome To Make Certificate Transparency Mandatory In 2017 (

An anonymous reader writes: Google Chrome will make certificate transparency obligatory for domains issued from October 2017. The announcement, by Google software engineer Ryan Sleevi, makes clear that the Chrome team will extend all necessary help to certificating authorities to prepare them for compliance in the next twelve months. 'Although the date is a year away, we encourage any participants that wish to have their use cases addressed to bring them forward as soon as possible during the next three months. This will ensure that the IETF, the CA/Browser Forum, and the broader community at large have ample time to discuss the challenges that may be faced, and find appropriate solutions for them.' The Certificate Transparency open framework, which has been criticized over privacy aspects, uses logs to which information can only be appended (not removed or altered) to provide an authentic chain of trust which is capable of detecting compromised certificates in hours rather than the days, weeks or months involved in traditional propagation.

Submission + - London's Streets To Get Free 1Gbps Wi-Fi, Mobile Charging And Phone Calls 1

Mickeycaskill writes: BT is to replace hundreds of phone boxes across London and replace them with ‘Links’ – modern kiosks that offer free, ad-supported phone calls, 1Gbps Wi-Fi, mobile charging and sensors that can support smart city applications.

The first kiosks will start to appear on the capital’s streets in early 2017, offering the fastest free public Wi-Fi service available. Each Link can support hundreds of users and also offers free mobile and landline calls to UK numbers.

An inbuilt Android tablet offers free local information and directions, and two 55-inch HD displays will serve adverts, public service announcements and community news. Each Link will be equipped with sensors that could monitor air and noise pollution, temperature, traffic and other urban metrics, allowing organisations and local councils to build smart city applications based on the Internet of Things (IoT).

Although its likely that not all payphones will be replaced with kiosks, BT has promised not a single iconic red phone box will be taken off the streets for what it calls the latest 'evolution' of the payphone.
