You are correct in pointing out this error of the parent comment (by SiVal). Each ball is indeed the sum of "n-1" bernoulli RVs, and the CLT does apply to these sums.

As btilly points out elsewhere, to actually obtain the correct limit, you have to normalize the sum correctly. Because of the way the scaling is done in this graphic, as you increase the number of levels, it's in effect normalizing the sum by dividing by "n". To get the right limit, you need to divide by sqrt(n).

In this sense, the CLT is a high-resolution version of the SLLN ("law of averages"). If you normalize the sums by 1/n, the resulting average converges to a number, the mean.

But if instead you subtract this mean, and normalize by 1/sqrt(n) rather than 1/n, the result converges in distribution, and looks like a normal random variable.

By less aggressive normalization, you get information about the fluctuations rather than just pounding it down to a number, as the SLLN does.

I used to TA a probability class for undergrads, and I found the demo to be perfectly reasonable.
Certainly they're serializing the entire user, and I'm guessing they just figured, "let the client sort it out." In other words, a lack of backend chops that would establish proximity and age (per examples in the blog post) based on the request and the user requesting the data.
We might, but if ending it simply routed the market from corn syrup to cane sugar, what difference does that make for consumers? It seems like the most you'd be able to say is that it might make junk food cheaper.
"Polygyny". I just learned something. And so did my spell checker by the way. "Polygamy" may have become gender neutral in technical circles, but I doubt the general population have caught up yet (though by the look of the relevant Wikipedia pages, they will soon).

Also, "polyamory" doesn't have the notion of marriage in it. Maybe that could be a useful distinction.
The article is admittedly bad and rather annoyingly he doesn't seem to show the actual results for the page he was talking about.

Personally, I dislike the feature and wish I could turn it off for my search results, it adds negative value for me and I keep meaning to set up a script to disable it but my quick experiments in the dev console screwed with the page layout.

Ah. So a remote access may be coming directly from the cache of a different CPU? That's something I didn't consider, and definitely adds another wrinkle.

I sense that the article is saying things in confusing ways, perhaps because that's the way computer architects speak (it always struck me as counterintuitive and confusing to measure a cache by its miss rate rather than its hit rate) or maybe it's this article.

There are only about 7 times more pixels in the modern system in your example.

Yet in the same time, x86 processors have gone from 25 MHz to 3,000 MHz, if not higher. That's a difference of 120+ times.

That's not even considering that basically all PCs (including laptops) and many mobile devices, now have CPUs with at least 2 cores, although 4 or 8 cores is pretty typical, too. Back then, uniprocessor PCs were really the only practical option.

The amount of memory available today is significantly larger, too. At the end of the 1980s, it was impressive to have 2 MB of RAM in a desktop PC. These days, we're generally looking at 4,000 MB of RAM, if not more. That's 2,000+ times more RAM today! When it comes to mobile devices, we're still looking at hundreds of times more RAM. The speed of memory today is also much faster than it was back in the 1980s.

And, of course, we've seen absolutely massive strides in video card technology in that same period of time.

Given those kinds of increases in the power and amount of resources that are available now, JavaScript and the other web technologies have absolutely no excuse for performing as poorly as they do.

I don't even buy the argument that JavaScript is much more portable than C was back then. SimCity was ported to many, many platforms. I remember playing it on PCs running DOS, on an Amiga, and even on an SNES at one point.
No, the budget was 400k. In what bizzaro world does 750% more funding delay project completion by five months? Just because you have extra money doesn't mean you should expand your budget to max out all your resources; try that excuse with any VC and tell me how it goes. Fortunately for Double Fine they're not actually responsible for how they spend their money.

An interesting point in the article:
"Coke suppressed demand for cane sugar formula because it would cost more to produce and consumers would not pay the extra cost."
The customers would benefit by spending less money on their unhealthy junk food. And on their healthy, reasonably-sugared food as well.
If we're going to pick nits, it would illustrate the "Weak" LLN, not the Strong LLN. The Strong LLN still holds here, but you'd need to plot the sample paths to illustrate it.

Both the format and version are in the same header if that helps. So there are a couple values in there you might have to change, similar to the couple values you would have to change in the url to modify version/format. So in that regard I think the difficulty or complexity of one or the other is pretty similar. Hope that helps explain a bit, but let me know if I missed the point of your question.
It's a fairly similar logic though, isn't it? They have other teams coming off other projects, so rather than leave them idle until Broken Age is finished or going to a publisher for a project, they decided to Kickstart another independent project.
Sure, but the CLT holds in very great generality -- to variables that are not independent, and to stochastic processes. Any demonstration is bound to be a special case.
I live in a state where Coke with sugar is widely available. The taste between that and HFCS is like night and day. Too bad the rest of the states do not have that choice.
Think about it like this, lets say we let people make Steel wherever they want and everyone starts making it in China, causing the local production to grind to a halt due to being unable to compete.

Now a year later, China decides it doesn't want to export to us anymore and bans exports of Steel to the US, now we are screwed for at least 6 months, since we don't have the ability to create the product anymore.

The difference with sugar is we do have an alternative available (corn syrup) so the loss wouldn't be as big.
The station is not meant for day to day "fillups." It is for long interstate trips... the kind where 30 minutes out walking or having lunch is quite welcome.
Higher percentage-wise yes, but not by its affect your paycheck. My property tax is half of what I paid in MA, and it's for a house double the size and half the price - in a suburb of Austin, with a shorter commute to downtown that I had to Boston.

I was just looking into inotify to reload nginx and various other services on conf changes. I guess I'll go with Watchman so I don't have to write a series of shell scripts.

I considered guard (https://github.com/guard/guard) and Nodemon (https://github.com/remy/nodemon), but Watchman has less dependencies (doesn't require Ruby/Node).

There's also Supervisor (Python) (http://supervisord.org/), but I think that is more process management. I'm not sure if it can do file-watching as simply as Watchman.
The amount of solar panels you'd need to charge a Tesla at supercharger rates would be ridiculous.

They may have solar panels, but that is just something cute that might make a small dent in the installation's grid power consumption.

However, you are on to something [1], though it's more for cars that are parked for long periods during the day. The point of a supercharging station is contrary to donating your vehicle's power to the grid.

It "tastes" like synthetic crap. Before I was put on dietary restrictions I made my own ginger ale, because the stuff that was sweetened with HFCS tasted acidic and far, far too sweet.

There are people who seek out and drink Mexican coke since it contains sugar (see also pepsi throwback). There were also jobs lost as the candy industry moved from the US to Canada and Mexico.
Not sure if this is related, but you often have to declare local variables volatile when using setjmp/longjmp because they do not preserve registers. It's one case where unoptimized C code will run fine, then -O will push variables into registers and break it.

If a foreign country is willing to force their citizens to subsidize our purchases of their sugar, steel, etc., I see little reason to object.
A multi-day power outage has happened to me 1 time in my 40+ years. My various internal combustion cars have failed maybe 5 or 6 times. That's a small sample size, but I suspect that overall the grid is more reliable than vehicles (electric or gas) themselves.
> The subsidies are such that a cattle farmer can actually make a profit buy growing corn, selling it (with subsidies), then buying corn back to feed their own livestock.

I fail to see how this is enlightening, of course growing corn creates a profit. If you are excluding the base profit of the corn, why wouldn't a subsidized market create additional profit?

Agreed that the most important point is that liquid carbohydrates and plain sugars are generally bad, and that that's 90% of what people should take away from discussion like this.

But it appears that there's still some particularly negative effects of HFCS relative to more typical sugars, too:

That's not intuitive, that's just familiarity. Intuitive means someone who has never seen it before can pick it up and go without too much training.
Or, the customers would suffer by purchasing more unhealthy junk food, which is what economics suggests will happen when you reduce the cost of something, especially when its demand is spurred by physical dependence.

That rat study came up 900 days ago in the last HFCS debate I saw here, and indicates mostly that rats seem to modulate their eating better with sucrose than with HFCS; it's also controversial.

The thread started with refactoring, and then moved on to IDEs - what I was trying to say was that if you expect to require an IDE to help you with tasks like that, you might not enjoy using Go very much, because usually IDEs tailored for an ecosystem with built in autocomplete, docs, refactoring etc are useful for languages where refactoring means changing header files, the inheritance hierarchy is complex, the std lib or API is really large, etc. (like Java, ObjC, C# perhaps). None of that applies to Go so I don't really see what an IDE would add above a text editor (I use TextMate for example), combined with a browser open at the excellent package docs here - http://golang.org/pkg/.
> DRM is some heavy burden that they basically bribe you to accept. I'm sure it's gone wrong for some people at some point

These two sentences reinforce what the OP is saying, you aren't arguing facts, you are arguing impact. OP is saying we are underestimating the impact DRM should have on our decision, to which you responded "it doesn't bother me". That fact isn't important to this discussion.

I also use Steam, enjoy it, think they are a great company, and won't be stopping anytime soon. However it is certainly true that unlike GOG their platform is based around DRM.

The "free" market, at least as we understand it, depends on a fiction: interactions between people happen in terms of transactions in private property according to enforced contracts. Neoclassical economics doesn't really consider what an efficient economy looks like when "killing someone and taking their stuff" is a valid action within the system.

We can get away with this inside a country, because governments monopolize the use of force, and so you can talk about "free" markets in terms of interactions between people in terms of market transactions, without factoring into the equation the possibility of use of force.

But as between countries, that fiction fails. Countries are in the state of nature. In that state, force is as valid an interaction as trade. Any discussion of the interactions between countries, therefore, must consider how force affects any trade dynamic between the countries.

So why do we keep a domestic steel and arms industry, even though it might be more efficient in terms of global GDP to let some other country manufacture those things? Because it's a huge disadvantage in terms of waging war to have your arms manufacturing done by some other country. We would have a hard time bombing China if our bomber aircraft were manufactured there...
I zoom all the time. Saves me from having to put on my glasses.
Uh. From a naive perspective, I'm quite willing to object to other people being forced to do something.
Sucrose is exactly half-and-half fructose and glucose; it is composed of one of each, bound together. This is important because it means that it can't be immediately absorbed into the bloodstream. It has to be broken apart first, and the enzyme that does so is in the intestine. This means that its absorption rates and effect on the glycemic index are different from HFCS. Diabetics care about this.

While I can't really argue against you, partially because you're tptacek and partially because you're not wrong here, it's quite irritating to see somebody have a good conclusion and faulty premises.

Also, stop with the scare quotes.
Why do they not use SSL? Every mobile app should use SSL to communicate with their API. Apple should look into making this a developer guideline (i.e. reject apps that break it).
>> Table sugar is ~50% fructose, HFCS 55%.

Actually, table sugar is sucrose, a different compound to fructose. Fructose absorption is actually faster in 1:1 fructose:glucose mixes.

So there are differences in the metabolism of fructose in the two situations, even if minor, and as a general point of chemistry it's not really correct to say that table sugar is half sucrose any more than it's correct to say alcohol is half methane.

But in general yes, HFCS as a substance is not the problem. HFCS as a subsidized foodstuff that gets wedged into too many things, that's the issue.

> The difference is, it wouldn't be okay if all our domestic steel production went overseas.

Why, exactly, wouldn't that be okay? We'd only lose "all" domestic production if foreign production were quite a lot cheaper, in which case the benefit from switching is huge and ongoing. If you're worried about wartime security, here are three ways to mitigate that concern:

(1) Stockpile. Order enough (cheaper, now that it's imported) steel in advance that we'd be able to meet likely short-term needs.

(2) Diversify. Keep an eye on the foreign supply and make sure that we're at least perserving the option to buy from more than one country so if one trading partner gets angry we can just switch to buying from another.

(3) Be polite. Stop invading and/or bossing around every other country on the planet, so our trading partners aren't likely to have good reason to want to embargo trade with us.

The fact that more international trade would mean we might have to actually care what other countries think is a pretty huge argument in favor of it.
To be able to grow, sell, buy, use and still come out ahead, you must be able to sell the corn for more than you can buy it for, which is nonsensical.
The article says nothing about corn subsidies which affect both HFCS and ethanol.
