Depending on how you want to look at it there are 2 or 3 types of networks on the grid depending on perspective.

On way is by looking at the transmission grid and distribution grid. On the transmission grid where you see high voltage lines and generators and power flows both directions withing this network. You are correct in this respect. The problem arises on the distribution network side where instead of high voltage lines and generators you have customers and low voltage stuff. Here things are basically designed to flow one way, which is to the consumers.

The other way of looking at it is with 3 networks being high, medium, and low voltage. With this view things get a little more interesting as there can be bidirectional power flow within each level but it becomes problematic when it is between levels.

With either view of the power grid it really isn't too big of a problem* if you or a few nearby people are providing excess power that your neighbors are using as you are all on the same substation that is fed with medium or high voltage lines and provides you with your nice low voltage power. The problem is that if too many of you are feeding power back into the grid it may outstrip demand and now instead of that substation taking power from the medium voltage network it now is trying to push power up into the medium voltage network. This is not what the current grid was designed for and the equipment at the substation while it can do it doesn't do it well. The same thing can happen between the medium voltage and high voltage networks although it is rarer but has happened. This also ignores the grid management aspect of things which is all in software and is basically a traveling salesman problem solved as best as it can be continuously.

These are not unsolvable problems but instead are engineering ones that people are working on. Companies are already designing better switch gear, beakers, transformers, etc to handle bidirectional traffic. The modeling, management , and market applications are being developed to handle many more points as well as having them be bidirectional. Granted these now require substantially more computing power but technology has progressed where getting that computational heft isn't an issue.

*The one issue you have with large scale intermittent distributed power (rooftop PV) is what I like to call the rouge cumulus cloud. It is a nice sunny day and he decides to blow in over your neighborhood, and then out. All of a sudden your local substation goes from pumping power out to sucking it down, then back to pumping it out. It doesn't even have to be this severe, just going from low draw, to high draw, back to low draw presents similar although not as severe problems.This is murder on equipment and a real bitch to deal with from a grid management perspective. To prevent this some local grid level storage at the substation would help to level the load making it much easier to deal with. So again not an impossible problem but an engineering one.

What about sodium and sulfur? those would seem to work for grid level storage and are actually being made and used currently even if not widely yet. Also that was a fairly silly assumption such as needing a battery to run the entire US for 7 days, but having a battery that could power 1/7th the US for a couple of days would probably be much more reasonable to avoid stuff like the Northeast blackout of 2003.

I agree with (*almost) everything you posted but would add that you and GP are missing the most useful (imho) reason to watch other people learn.

I have a couple of MMOs I play but there was areas where I would just get stomped, no matter what I did in these areas I just couldn't turn it around. Then I found some videos by guys that were actually good in the areas I was weak in so I watched them to see what they were doing right that I was doing wrong...and it worked, now areas I used to absolutely dread I actually find challenging and fun and I never would have figured out where I was going wrong without watching others try different strategies that actually work.

*-But as far as Pre-Orders? I thought Aliens: Colonial Marines and Watch Dogs would have killed that practice, after all now we can't even trust what we see with our own eyes as it might all be mocked up bullshit. If somebody wants to spend their cash sight (literally) unseen? I'm all for people making their own choices but until we see actual real penalties for mockups and "vertical slices" I know I'm not trusting any game dev or publisher, I want to see the game actually running on real users' PC and hear from them whether it "is what it says on the tin" as the Brits say or if its the next A:CM or F3AR big pile o' shit.

Besides everyone is ignoring the obvious in that we already have this in the form of DLC...and look at how well THAT particular clusterfuck has gone over, with games like Evolve announcing the fucking DLC before we even saw a single screenshot!

We have ALREADY seen the plague that is DLC, so bad that "horse armor" has become a we REALLY want the DLC now made by a bunch of amateurs with ZERO oversight or control (because we have all seen how bad Valve has gotten with their "hands off" policy on Greenlight and early access, to the point that reviewers like Jim Sterling can make a living just making videos of all the shitty content crapflooding those channels) which the publisher just slaps another promo for and takes their cut?

BTW for those that say "poo poo, its for the devs poo poo" I would point out that the actual ones that made the mod get a lousy 25%, with Valve and the publisher splitting the other what fucking universe is not even getting a lousy third of the money being made for what you worked so hard on considered a good deal? Nope, sorry, this fucks the gamers by giving every incentive with ZERO risk for the devs to just crapflood like greenlight, this fucks the good mod devs TWICE by making them compete with a crapflood AND by only giving them a pittance of the money, and if that wasn't enough it fucks the community because anything worth actually looking at would quickly be ignored as the gamers saw an assload of "horse armor" level bullshit and would learn not to even look at mods, just as many like myself now don't give greenlight games a second glance.

The only ones this would have been good for long run is the publishers, who would get money for basically nothing, and of course Valve who would make money on the initial sales AND make money when people stopped using mods and bought more games instead of continuing to get value from games they already owned with mods...but I'm glad to see that throwing a shitfit actually worked for once, I figured they pull a MSFT with Windows Mist&ke and just flip users the bird until the whole thing was a mess and then try to fix the damage once everything went downhill...think if we have another shitfit we can get Steam to clean up Greenlight and Early Access?

Connectivity is huge, but it's only one of the ingredients in making this decision.

If you want the app to work for them outside of the corporate WiFi, you have to host it on the public internet, where all attackers are equally welcome without regard to skillz or skripts. Are you sure that server is secure? What about tomorrow? Are you patching it? Are your users securing their devices properly? Uh oh, it's the new version of Heartbleed, go back three spaces.

You also have to consider performance. Is this something that your users will use constantly for their jobs, or occasionally for some rare piece of info? If it's going to add one second to every screen, and you're asking people to tap their way through 600 screens a day, the inefficiency is going to cost you 10 minutes worth of payroll per user per day. Maybe you make that up in hardware costs if you force your users to bring their own smartphone to work. Maybe the sluggishness just makes your users miserable throughout the day. Or maybe it simply costs you a lot of money.

On the other side, if it's used perhaps once or twice a day by 2000 people, poor performance and connectivity issues won't be nearly as important as savings on developer costs and time to market, Or if you have only a half dozen heavy users, perhaps you're willing to eat the payroll cost of an hour per day instead of spending them on development.

It's a question best answered by the money.

I'm much more cynical, and I don't think Pepsi is giving in to anyone. I think they're trying to exploit people's fears that "OMG chemicals bad". It's more like they're advertising "We're the only brand that dares to print arsenic-free on our products."

I think the real problem with Diet Pepsi and Pepsi Max is that they taste more or less like regular Pepsi. Their advertising slogan may as well be "Pepsi - for when you can't afford actual Coca-Cola."

How many vulnerabilities is there in Ubuntu 6? Debian Sid? Windows XP is FIFTEEN YEARS OLD and was designed to run on a Pentium II 400MHz with 128MB of RAM. If they are too damned cheap to upgrade or replace a PC that is a decade plus old why should that be MSFT's problem? Apple doesn't support the G3s and G4s either but you don't see anybody trying to claim that as any "proof" of anything.

As for your other point its nothing but moving the goalposts and therefor meaningless, because we both know if the numbers were reversed the FOSSies wouldn't be arguing about what "level" the vulnerability is, which just FYI means exactly jack and shit as we have seen with tricks like the "WTF" virus you can use a low level vulnerability (in that case unprivileged user ID spoofing allowing the attacker to send a message) to then effect a higher level attack (user thinks message is legit, clicks on link provided which takes user to a page filled with zero day attacks) so the idea of "levels" really doesn't mean shit anymore.

+ - Microsoft's K-12 CS and H-1B Visa Agenda: From Think Tank to Law of the Land

Submitted by theodp
theodp writes: Led by Steve Ballmer, Bill Gates and Mark Zuckerberg, with corporate contributions from the likes of Microsoft and Google, a $30M campaign to promote K-12 computer science education was a smash success, winning over the President and lawmakers, who are poised to make CS a 'core academic subject' in a rewritten No Child Left Behind Act, which could result in hundreds of millions of dollars in new spending that the tech giants suggested could be funded using fees from additional H-1B visas they're coincidentally lobbying for to bring in foreign programming talent. Since the NY Times' Eric Lipton just won a 2015 Pulitzer Prize for investigative reporting that shed light on how foreign powers buy influence at think tanks, it probably bears mentioning that Microsoft's 'two-pronged' K-12 CS and H-1B visa agenda — which is on the verge of becoming the law of the land — was hatched at an influential Microsoft-backed think tank mentioned in Lipton's reporting, the Brookings Institution. On September 27, 2012, the Center for Technology Innovation at Brookings "hosted a forum on STEM education and immigration reforms and how these policy innovations can recharge American competitiveness and economic opportunity for current and future generations of workers." Keynote remarks were delivered by Brad Smith, executive VP and general counsel of Microsoft, who took the occasion to introduce Microsoft's National Talent Strategy. "So, Brad," asked the Brookings Institution's Darrell West, "you're the only [one] who mentioned this topic of making the problem bigger. So, we galvanize action by really producing a crisis ['like climate change', as Microsoft partner later put it], I take it?" Smith replied, "Yeah, I think we have the opportunity to do two things...the immigration and education issues are, to some degree, opposite sides of the same coin. The coin itself is about the need to have people with the right skills to do the work that the country needs to get done...And, you know, it will require additional people from outside the United States in the short term [20+ years, according to the WSJ] but let's use that to help address the broader and to some degree deeper and longer lasting problem that we face with respect to our educational system. It also gives us the opportunity to connect with people who may not have seen this connection or to connect with people who care more about one issue or the other, but bring them together" (video @ 49:24). Fittingly, in attendance two years later at the White House as President Obama tackled the national CS crisis as he 'learned to code' from a nonprofit headed by Smith's next-door-neighbor at the Brookings-trumpeted and nationally-covered Hour of Code event was Fred Humphries, a top Microsoft lobbyist and Brookings partner. According to visitor records, Humphries returned to the White House the next day with Smith and Microsoft CEO Satya Nadella to quietly meet with officials. While in D.C., Nadella also lobbied for high-skilled immigration. And that, kids, is How a Bill [Gates Agenda] Becomes a Law!

There are many variations of this. One I *think* works (but I don't have the skill to check) is that the universe is "sort of" like a simulation, where only macroscopic items have a defined state, but the macroscopic items have defined contents and a defined energy spectrum, and when you arrange to "look closely" at one of those items, it alters the state of the rest of the item in a computationally conservative way, such that you can't detect the difference until you start getting really close to the limits of the simulation, at which point you get results that are statisticly chosen to confirm the conditions of the macroscopic item. So if you split off a bound pair of subatomic particles, they are so pair has defined characteristics, but there is no definition of the components until you look.

Think of it as a way of simplifying the model so that it can run faster on the host computer. The actual "host computer" may not really exist, but if it did, this would be the most efficient way to program it.

What he is talking about is DIVX (all caps), named to make people think of the OTHER DivX , which was an attempt at "DRM in a box" that went over about as well as a loud ripping fart in an elevator.

I predict other than the *philes (the same folks that bought Beta, Laserdisc, and anything else that claimed to be "better" than the rest) 4K is gonna flop as bad as 3D TV, the reasons why are numerous, 1.- DVD is "good enough" for the majority, which is why after all these years BD is still not a blip compared to the massive DVD install base, 2.- The bandwidth in the USA to stream 4K without getting capped? EXTREMELY rare, most folks would be lucky to be able to watch 2 vids before they get capped, 3.- The not insignificant investment from users that really like what 1080p looks like now, and 4.- The fact it won't work with anything they already have, thus causing the "I gotta buy the Beatles albums again" syndrome which in a "jobless recovery" isn't gonna fly.

Considering the majority of PCs still don't come with BD? I'm really not worried about 4K DRM, it'll be another WMA, only bitch is the wasted die space used by your GPU and/or board for this shit you'll never use. Damn, now I'm gonna have to grab that R9 270x before they have time to add that shit.
