I can't speak for OP, although I basically agree with you and OP simultaneously.

However, look at it as an optimization problem. CC testing standards and format may be ideal testing tools for 49 minutes 5th period after lunch 5 days a week in a 40 person classroom, performed in perfect lock step by all 40 students, only failure mode is repeating the entire class or developing a hatred of the topic, aka standard public school experience.

However, what does "alignment" WRT KA mean when the educational experience has completely changed? Its analog, you can watch a video 50 times will you get it, jump back and forth, all that. I'd propose the "best" testing technique for that environment probably looks a lot like KA and not so much CC because you need instant feedback and simple questions. Its not quite as good as personal 1 on 1 tutoring, but its better than sitting in class, more importantly the experience is inherently different than sitting in class...

The proposal in the linked article seems to be that KA epic fails, solely in "alignment", because it doesn't test like CC, which is trivial to test and prove and analyze statistically. Factually looks like a good study. Maybe it fails the relevance test because "alignment" is fuzzy to me (maybe it has a special jargon meaning among CC teachers?) I think MAYBE OP and I are concerned that KA aligns pretty well to a decent curriculum (CC) WRT topics and order of topics and presentation standards, and I hope KA doesn't ruin the KA assessment portion to better match CC assessments solely to get a checkbox somewhere.

Maybe we can abstract out KA from the discussion. I'm tolerably good at math and have tutored people. If you define alignment with CC as slavishly following their assessment technique at all times even though I'm 1 on 1 in an ongoing human conversation, such that everything I speak must statistically match the CC assessment percentages in style, tone, and technique, that's ridiculous. If you defined alignment as I'm talking about sets of linear equations with infinite solution set the same general time, order, and way the CC talks about it, thats OK, even if I assess a tutored student the "wrong way" by asking the wrong type of questions (which may very well be the right question for that kid at that moment while also being on average the wrong way to teach all American Kids in a 40 person classroom)

Its seems reasonably non controversial that CC curriculum and assessment are local maxima on society wide averages for teaching math. It seems reasonably non controversial that KAs assessment tools seem to be a local maxima for computerized delivery of help to kids that need extra help. I (and possibly OP) don't think it reasonable to trash talk KA because the local maxima of effectiveness for society as an average whole in a classroom setting doesn't necessarily match KAs local maxima of effectiveness for "kids who need help at home". The danger is screwing up KA enough to make it useless for the kids who need it after school, just to achieve a marketing checkmark.

The depressing part is how "invisible" this extinction rate is to most people. It's happening just slowly enough to barely register in people's memories.
If you want leverage (over the long term) I would try to focus on the areas that a 'coding bootcamp' could never cover in any significant breadth. A few that come to mind are: database administration, devops, and InfoSec.

That being said: the best leverage, no matter what your chosen path, is to be
GREAT at what you do.
Why? The point of your "cluster" is clearly not performance.

Seems useful to think of this from a computer vision standpoint. With vision problems, you often first need human annotation, and unless human beings can agree to a high degree, there are going to be problems. The "number of clouds" in a picture is an ambiguous enough concept that I can't imagine everybody agreeing.

That said, if there is clearly _one_ cloud, I think most annotators would agree that there is one cloud (and not, say, infinitely many).

So going from that, you can frame it as a constraint optimization problem. You want the largest possible collection of droplets to be a cloud, without accidentally defining all the clouds in the world into a single cloud. There has to be a loss function for the cloud-ness of a set of droplets based off how dispersed the droplets are in it.

Think about the fill bucket in Microsoft Paint. A single pixel hole allows the entire image to get painted one color. We don't want our definition of cloud to leak along the single droplets that exist in the air to define the entire atmosphere as a cloud, but we definitely want to group certain things together as clouds.

Hopefully that is food for thought for someone who is better versed at the specifics of anything I just said!

Outrunning a burnout
One sophistry problem is we will "ALL" theoretically take and pass Algebra, so the teacher does not have the luxury of specialized jargon, the teacher MUST be able to present it to the entire general public. A general education teacher is expected to present effectively to the general public as the core of their job, its not a nice to have or wouldn't it be interesting if it were possible.

On the other hand, only maybe 1% of the population has to suffer thru garbage collector theory in CS classes, and of that 1%, maybe only 0.0001% ever implement a GC "in the real world" and can understand that post. There just aren't that many GC programmers and there are a lot of humans in the general public. In that case jargon is perfectly acceptable, even expected. Also the core of a programmers job is rarely making public presentations.
Yeah you can do that. I've messed around with emitting square waves but not much else. There's also a problem with that where plugging something into the link port triggered an interrupt that diverted control back to the kernel which would then try to initiate communication with another calculator over the link. Not the desired behavior. In the best case this would cause serious lag. In the worst case, a crash and hard ram reset. You had to patch the kernel in order to output sound. Fun stuff.

I'm pretty sure Ada's ranged integer is tested dynamically, not statically. It's still a cool language feature. To get a static detection of integer overflow, I think that you need to use some variation of dependent typing.

So it's possible in Liquid Haskell. And of course, it's easily done in dependent-typed languages like Agda, Coq, and Idris.

Edit: I had earlier written Nim has this static range checking capability, but it looks like it also uses a runtime check.
Quite interesting.

Actually one of the first bootstraped environment I read the implementation multiple times was the Smalltalk Blue Book, which is quite interesting for meta-implementations.
Video is great! Still it's weird, I can even show somebody a setup with Synergy running, and until the moment they move their own mouse cursor over that hard boundary at the end of their monitor, it never seems to click...and weirdly people are kind of resistant to it.

I almost think the next Tron movie needs a character named Synergy that bashes down arbitrary walls between systems to really get the idea out there ;)
> especially seeing how trivial it is in x86 assembly (add the numbers, then check the overflow flag)

I'm no expert, especially not on modern x86 processors or compilers for them, but I suspect it isn't so trivial as scattering such instructions may affects branch predictor tables and indirectly degrade performance in other parts of code.

I grew up writing poetry. I have a love of words, metaphor, literature, sentence structure, composition (in music as well). But the base form is mathematically expressible, that is the foundation of every perception to me. It's the only thing that can't mutate into something else - it can be used to express that which is not itself, but mathematics is formal structure itself. The symbols and organization are typically just decoration. It either makes sense or it doesn't, in that abstract form. I don't find that kind of unity really anywhere else. I appreciate the compliment, though.
I looked into this setup but it gets pretty ridiculous if you want to do any gaming. You want 4k @ 60hz with 4:4:4 color sampling at a reasonable <40" but it soon begins to feel like you're hunting a rare animal. With only hints and whispers strewn throughout a dark abyss of forums threads and amazon reviews. The kind of places where people put AMD driver revisions in their signatures. I don't think we're quite there yet.

This warms my heart -- not just that the article doesn't take a political position, but that it was probably printed to disclaim one. That kind of defensive demonstration of journalistic integrity reminds me that there are idealistic people working inside these big-business papers.

It's small news, and maybe other people are reporting on it too, but I like that I read it at the Washinton Post first.
Ideally, Assuming that intel's chips will be as good as other's without a bribe, and tablet manufacturers already had some successful designs with x86, than all it takes is a small nudge.

It could be in the form a bit of lower prices, or some nice bundle with other technology intel will (intel and micron make flash together, or desktop chips,etc), or some unique technology that intel will develop or acquire, etc.

But first ,let's get to the point where intel is equal including in price.

Intel might want to enter the IoT market this way, but all the other chipmakers I've seen aren't going this route. They're trying to drop the power consumption and cost as fast as they can and let someone else design the fancy glasses.

Intel's record in consumer electronics to date is, well, pretty awful. So the expectations are pretty low here. And, again, nobody gets 65% margin on consumer products.
Can you provide a side by side comparison with Google's spellchecker?
I like the idea and ran a node for a year or so, but the truth is I never used it to actually search - the results were astoundingly bad 80% of the time.

The rest of the time they were just about ok and I'd find what I wanted on the 2nd/3rd page.

It was a good way to throw up some left-field results though, and for that reason it's worth keeping a node going if you can. Might get it up on the new VPS.
How does Starbucks knows how to grab my MAC Address?
To all hacker out there, how in the world can a website grab your mac address from the browser http://oi61.tinypic.com/s263ib.jpg. I've heard responses from "it is not possible" to "they use flash". But this happens every time I go to Starbucks and I am pretty sure Flash is not used.

I'm posting on HN to get the low down if anyone who has ACTUALLY first hand know how on how this is accomplished.

While I like the idea of Khan Academy, there are problems with some of the contents of the lessons. For example, the lesson on Hooke's Law definitely has issues:

> Win 8.1 also allows to set the dpi independently for each connected monitor. That's important when you connect a 4k screen to an average notebook or a tablet to a TV.

Yes, that's one of the biggest missing pieces in KDE so far. DPI changes universally, so you can't comfortably use monitors with drastically different resolutions in multiscreen setup because of that.
It doesn't have anything to do with ARM. Intel used to have an ARM license but they sold it to Marvell just as the iPhone came out.
The article above states (or assumes?) that Intel sold off XScale to Marvell when the iPhone ship sailed without them.
There's a good euphemism
I think it's important to ask two questions:

1. Is this a bad thing for humanity?

2. If it is, how can we stop it?

I'm not sure the answer to 1 is, "Yes." If an organism is useful to us, we domesticate it. The rest of nature (while sometimes pretty) doesn't affect our survival, actively harms us, or is too hardy to unintentionally destroy (cyanobacteria). Nature is an extremely complex system, but let's not pretend it was a precariously-balanced eden before we came along. Most of nature is animals suffering; starving, dying of disease, or being eaten alive by others. Nature visits unnecessary suffering upon animals on a scale that we cannot imagine. When humans do the same, it's animal cruelty. I see no reason why we should try to prevent one but not the other.

But let's say nature is worth preserving, at least until we understand it better. How can we preserve it? I know of no civilization that has voluntarily reduced its resource consumption. It seems the only solution is to invent our way out of the problem. That means advances in agriculture, biotech, and energy.
Interesting that this article, originally investigated and published over a year ago, mentions phenmetrazine - derivatives have just started to appear on the grey market....

--edit-- I'm amazed at the quote from Caldicott at the end. WEDINOS is widely used by the NPS community to check the identity of their substances. It allows the project to map out drug emergence and for the users it provides a little safety check. For the founder to have been someone who considers drug use a disease and prohibition like an antibiotic seems to go against the open, harm-reductive effects of the service itself.
Itanium was not "an adoption" of PA-RISC. It was a completely novel design co-developed with HP after HP researchers argued that VLIW was the next step forward.

It did, however, manage to kill several of Intel's potential high end competitors with nothing more than hype.
Haha, 7Figures2Commas got pwned.
Sufficiently smart compilers never showed up where it mattered most for Intel:

Turning branchy C/C++ system and apps code into explicitly parallel instructions.

And arguably, they can't.

Sufficiently smart compilers for GPUs aren't sufficiently smart. They work by imposing sufficiently dumb limits on programmers instead.
This was enjoyable.

I wonder if software exists that is aware of the overtones of each particular note of a given instrument. Theoretically, this would be a more precise way to pull out a chord from a recording without having to manually compensate for them later. Standard Fourier analysis is based on sine waves which aren't the best model for complex tones like that of a piano or a 12-string guitar.

Mathematically, the best approach I'm aware of in the long run would be to study the harmonic spectrum of the exact instrument as closely as possible, and then perform inner products against the spectrum of the mystery sound being analyzed. There's no guarantee that the note-vectors would be orthogonal (probably not), so the problem becomes more interesting in that you might want to perform a sparsity maximization on the resulting output - that is, look for the least number of notes capable of matching the recording within epsilon error in sample (or spectrum) space. Sparsity maximization is NP-complete, so a good way to approximate this is to actually perform L1-minimization using linear programming. Another approach might be to look for a balance between the absolute error term and the sparsity term.

The comments seem disportionately negative towards Snowden. I have rarely encountered anyone in real life that knew much about Snowden let alone had a strong conviction about him one way or the other.

Maybe there's so many negative comments because people who are against something or someone are more likely to post. But it also seems like a good candidate article for certain interests to subtley influence public opinion.

Is there a way to get 60Hz on a mac you think?
Lets say you have a bunch of textures and want to create a pattern for each of them.
Most people would do it like this:

for(var i=0; i < texcture.length; i++) {
texcture[i].onload = function(i) {
pattern[i] = ctx.createPattern(texcture[i], 'repeat');
}
}

Witch will summon the evil closure:

for(var i=0; i < texcture.length; i++) {
texcture[i].onload = (function(index) {
return function() {
pattern[index] = ctx.createPattern(texcture[index], 'repeat');
};
}
})(i);

But if you used my silver bullet: Avoid anonymous functions - the root of evil ...

for(var i=0; i < texcture.length; i++) {
createPattern(i);
}

function createPattern(i) {
texcture[i].onload = function() {
pattern[i] = ctx.createPattern(texcture[i], 'repeat');
}
}

However, over the past few years it has become evident that changes in the metabolic function of muscle itself plays a more direct role in the genesis of insulin resistance than previously appreciated.

This makes logical sense. Given that people with CF do not process fats correctly, tend to be severely underweight yet are highly prone to developing CF Related Diabetes, fat just about can't be the right explanation as to cause.

On the other hand:

The central thesis of the glucose–fatty acid cycle is that elevated plasma FFA concentrations limit glucose uptake in muscle by inhibiting the oxidation of glucose (33). Thus, according to this theory, the genesis of insulin resistance lay entirely with the increased availability of FFAs, and the muscle responded normally to that signal to limit glucose uptake and oxidation.

Can anyone tell me: If you are chronically insufficiently oxygenated for some reason (like lack of lung function), would that contribute to this process? I mean, it sounds to me like insufficient oxygenation of the system would play a role here.

Any takers?

Hi,

I am mainly interested in solutions aimed at web-development.

Throwing in another two cents here.

I'd say I lean toward introversion, though I've tried to spend a lot of time learning to engage in social situations, and do fairly well. I've been a full time trainer, and participated in various levels of managing teams to good success (if I do say so myself).

I like the people on my team, and I like going to lunch with them, but I hate Team Lunches. I think it has to do with how contrived the social situation feels, and how much I feel like someone is trying to push me into their vision of a sociable team.

One of my pet peeves is finding out someone wants to push Company Culture and that means getting everyone together to do cheers and chants.

There's nothing inherently wrong with cheers and chants and team lunches or whatever you want to do, but you love your job and who you work with and not want to be forced into a contrived social situation where you're supposed to bond. I bond just fine with my coworkers after we decide which thai place to go to on a given day.
