Comment Re:As a parent, which requires no testing or licen (Score 1) 700

2. Homeschooling academics can be more rigorous. As an engineer, I consider math to be the foundation of all my success, and common core has turned math into a laughingstock. Enter homeschooling, where I can pick the "Singapore Math" curriculum. Singapore typically scores number 2 every year on the international math achievement exams, their math program is entirely in (British) English, and I can have their exact program for my kids instead of common core.

Losing mod points to respond to this, but as a math teacher I can say based on substantial study and practice that you are drinking the wrong cool aid about common core. To see why you have to understand what common core is and isn't. Common core is just the set of standards, and it's important to read a bit of them to realize what that means and doesn't. Everything else that isn't written in the common core standards, but yet people still incorrectly call "common core" is just an attempt at implementation of the common core. If you see a given incomprehensible homework assignment, that's the implementation, not the common core. The standards don't give implementation details, the teacher, textbook, and/or district provide those.

Before I go further though, I will agree with your first statement. Homeschooling can be more rigorous, but as I am considering homeschooling my children, the thing I would do would be to implement the common core to it's fullest extent and attempt to exceed it.

I'll cut to the chase and give you the summary: the common core standards are more rigorous and are a substantial improvement on every state standard before them that I am aware of. They embody the important parts of the best of education research and the math standards for example are substantially based on the previous work of the Principles for School Mathematics developed by NCTM. So if a given implementation is bad, it means either the teacher or textbook are not as good as they could be, not that common core is bad.

Look at the Standards for Mathematical practice: http://www.corestandards.org/M...

and the following specific standard: CCSS.MATH.CONTENT.HSA.REI.A.1

Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.

A classroom attempting to implement the standards for mathematical practice to fully meet the standard above will be leaps and bounds above a traditional classroom in terms of rigor, cognitive demand, ability to reach diverse students, etc.

Also having studied the TIMMS study in depth I can say that the reason Singapore does well on the exams isn't necessarily related to their curriculum, but likely has more to do with parental support for education.

I've come to agree on this. In cases of infrastructure free market forces don't work well enough to work for the good of the consumer. Telephone, internet, highways, etc. The costs of entry are so high there's not a real market and corruption etc as you've explained well take over. In that case I agree government is better than a natural monopoly, but I don't think government ownership is the only option. An in between option is possible where a independent government sanctioned organization owns the infrastructure but has a bit more flexibility and incentives to operate efficiently. Now it may not work, think the post office where poor government oversight hamstrings their ability to make decisions, but even there it's probably better than outright government ownership. The post office does actually do their job fairly efficiently and at low cost. But in that case you're basically asking for smart regulation, and that's tough to do. Not all regulation is bad, bad regulation is bad but smart regulation is hard to do. There's a chance though it can be better than outright government ownership and retain the benefits while still adding flexibility. The structure can be anywhere on a continuum from full government ownership to full independence or somewhere in between. The more freedom the more chance for more efficiency but the more chance for failure.

Yeah you sound like you know what you're talking about, except you don't. I know the studies you read make it sound easy, except it didn't turn out to be so easy. If it were that easy people would be investing billions into it to earn the profits that the oil companies are currently earning on petroleum. The studies you read, I read too, and they are smaller scale, talking about hoping to scale up. Optimistic pilot studies are practically legend and this seems to be a case. When trying to scale up, difficulties seem to have arisen. When you look into the companies that are trying to scale it up, it isn't working out as well. The contaminants are happening, the yields are lower, the costs are higher, etc.

Yeah you've repeated the rah rah promising sounding stuff from the decades old NREL reports. It sounds really great, I've read those too. But read them carefully--they're very initial studies that never scaled up. They are full of statements to the tune of "when scaled up to commercial volumes". Excepts it's been decades and no one has been able to do it. I've followed a number of the experiments of people trying and it doesn't seem to be as easy as the NREL papers made it sound. The open raceway ponds get contaminated with lower oil strains and don't produce the oil at the rate the papers hypothesized and the closed systems are expensive and difficult to operate. I'm not saying it's not possible, but the magical oil from algae to produce 100% of our transportation fuel isn't going to be nearly as easy as it seemed. Possible? Maybe yes, but probably not economical anytime soon. Think of it this way, if it worked, oil companies would be pouring billions into making it work rather than spending those billions drilling underwater or paying despotic dictators. They don't care where their oil comes from and if biodiesel from algae worked they'd be all over it to sell that to you cheaper than the other oil companies. They are researching it and possibly when crude oil is 4, 10, 20 or more times more expensive than it is now then algal biodiesel will be cost competitive. It wasn't when oil was over $100 a barrel, but it's possible something will be figured out that hasn't been in the last few decades to make it feasible by the time it gets back there. Or maybe it won't.

Unfortunately, the US does not have free market capitalism on broadband communications. In most areas it is either monopoly or duopoly

That's what a free market will usually naturally gravitate to. Competition is bad for all competitors, so cartels or monopolies are strong attractors in the system. If you want competition and choice you need market regulation to make it happen.

Comment Re:I prefer a tablet for some things to a smart ph (Score 2) 307

I kind of want the opposite. I've got a big, capable laptop at home, and several computers at work. When I go out, though, I'm not going to do any real programming or make a presentation or things like that when I'm at a cafe with my wife, or sitting on the train home from work. I'll surf the web, read a paper or play games. A tablet lets me do that just fine.

A small, light laptop has too many compromises; little memory, slow CPU (that gets throttled after more than a few seconds at 100%), small screen and keyboard. And it's still much heavier than the Tablet Z I carry. The tablet is light and thin enough that I really don't notice it in my bag at all.

We're all hunting for the impossible: a matchbox-size computer with the power of a workstation and a 40" screen. Instead we have to compromise. And we all end up with different compromises. I've even thought of cancelling my smartphone and go back to a small, light feature-phone. It's cheaper, more durable and the battery lasts for a week. Use only the tablet for apps.

Exactly this. A well encoded DVD is plenty good enough for anything other than very large screens and for people with insanely large screens they won't be buying 4k because it will cost more than their homes.

Nope. I have a 46" 1080p HDTV and sit around 10 feet from it. I have compared DVD and Blu-ray versions of some of the same movies that I bought on both mediums. The difference is night and day. If I watch on my 1080p computer monitor, 23" and I sit about 2 feet away, it is even more noticeable.

DVDs annoy the piss out of me because they are so blurry. Blu-rays might not be the high-resolution king anymore, but they are certainly not blurry.

It teaches good habits (but with the demise of Turbo Pascal I am unable to suggest a worthy compiler).

May I suggest the Free Pascal Compiler with Lazarus as IDE. There's even a Lazarus add-on to automatically configure it for pupils/beginners.

Disclaimer: I am and have been one of the FPC developers for the past 17.5 years (also starting originally with Turbo Pascal, and then moving on to FPC once it became clear Borland wouldn't come out with a 32 bit DOS version).

Submission + - Windows 10: Can Microsoft get it right this time?

An anonymous reader writes: Later this week Microsoft will provide more details of Windows 10, most likely focusing on how the new operating system will look and feel on smartphones and tablets. According to Mary Jo Foley, Microsoft is likely to unveil a version of Windows 10 that's expected to work on Windows Phones and smaller Windows tablets running ARM and perhaps Intel processors. Microsoft will be hoping that by making it easier for developers to build for tablets and smartphones it can take some of its dominance of the desktop world and port that to the mobile world. That may help a bit, but will not in itself create the breakthrough that Microsoft wants: when it comes to mobile, Microsoft's Windows Phone is still a distant third in a two-horse race.
