Suppose the formula in A1 is =A1+1. What should be the displayed value in A1? How long should it take to display that number? This is a simple case, which clearly diverges. There is no simple way to determine from a general formula whether it will be convergent or divergent. In the interests of definiteness, Excel defaults to just disallowing formulae with this kind of indecisive output.

The article says

“The response, basically, was ‘You are not welcome here. We do not want you to come back, at all. We are not interested in engaging, and steer clear,’” said Mr. Stephens. ”I was just amazed that Hendrix was, like, so opposed to this idea of even engaging in a conversation two years later,” he added.

Whomever reached out to the press office of the college was told the following

"Asked for comment, Hendrix spokesperson told Betabeat, “While we regularly invite and promote speakers on a variety of topics that are relevant to our academic program to campus for the benefit of our students, past and present, faculty, and the community, Hendrix does not provide a venue for individuals to promote personal projects.”

I can't see anything to indicate he is unwelcome. He couldn't give the exact reason why they would not let him present his work (Which is obviously disappointing).

The article title is misleading.

This attitude drives me nuts. It's a message board. What do you want from me? We're not settling public policy, we're discussing it. How does it help anyone for me to issue prolix disclaimers about how certain I am about things? How does that even matter? If you think I'm wrong, say I'm wrong, and preferably, why you think that. If I agree, I'll say so. I'll do the same.

I have no actual "authority" on HN.
I saw some research talking about polynomial complexity for N-Queens come up in a google search. If someone has published a paper about a problem like this generally means that the time-complexity they're writing about doable but very hard.

I didn't click any of the links though, since I wanted to keep working the problem.

Not necessarily.

His rationale is highly self-serving, bordering on disingenuous:

"I was just amazed that Hendrix was, like, so opposed to this idea of even engaging in a conversation two years later,” he added."

Pulling condescending word games about what he's doing as "a conversation." "Hey man, I just want to talk." Well no, and this tack is practically straight out of the book, "The Gift of Fear."

"It got me thinking that this had nothing all to do with Hendrix and everything to do with the way the entire system is designed."

Ah, see? It's not just Hendrix, but the entire system. Nothing personal, you see.

$200 is the cost to buy the phone.

In Europe, that's a down payment on a standard financing deal, and after the phone has been paid off, your monthly bill goes down.

In America, that's the price to straight-up purchase the phone. Your monthly bill will be the same regardless of whether you bought your phone from the carrier, or brought your own.

The controversy on Hagel's nomination has very little to do with his party line. Instead his questionable views on Israel are making him a choice that is difficult to sell - both to Republicans as well as Democrats.

Not saying that Hagel is such an outliner, but it is easy to nominate a fringe candidate of the other party and then pointing fingers when his own party does not support his views. Of cause something as sneaky as that would be unimaginable in real-world politics, and I am probably just watching too much House of Cards.
This article is a well-meaning summary of a project the author doesn't understand, and that cannot live up to its hype. Consider the following:

1. There are any number of electromagnetic fields present in the atmosphere, caused by power lines, radio transmitters, lightning, and many other sources.

2. Notwithstanding the above, in a typical location, "harvesting" the sum of all the fields cannot produce any useful power.

3. There's an exception -- being located close to a commercial radio broadcasting station or beneath power lines.

4. In such locations, one might be able to harvest a small amount of power, but one doesn't want to live in such a place because of the possibility of long-term adverse effects of strong electromagnetic fields.

5. The above risk is well-established enough that many governments require warning signs near radio transmitters:

>You can split it into a million micropayments whilst you're at it; it still doesn't stop the information leak.

Yes it does. If I split one payment into three different sizes and send them hours apart while I'm sleeping, from a shared eWallet used daily by 1000 other people, you think that is going to be traceable to me in any way?

Not a chance.
Cool. Take it a step further and make it so we don't have to edit the HTML/CSS code.
Vitamin D Supplements: Is What You See What You Get?
You also might want to look into R (I would recommend using R with RStudio, a fairly powerful, but easy to setup IDE). I have a feeling that if you know SQL, than learning a programming language is well within your abilities.

The biggest difference that I have seen regarding the Excel vs programming issue is the level of transparency that is provided in each. In excel, you get immediate validation of your functions and operations because you can see the results at each step. However, the formulas/functions themselves are 'hidden' and as the number of operations gets larger, it gets increasingly difficult to track and control the process. This makes debugging a nightmare. With programming, the results of your operations are much less transparent, but as you get familiar with the language you learn tricks to quickly summarize your data in ways that provide meaningful feedback for what you are trying to accomplish. More importantly, your script contains a concise record of all of the data manipulations and operations that you are performing, making debugging a much simpler task (compared to a monstrous spreadsheet).

An additional benefit to programming is that, after a certain level of familiarity with the language, your productivity increases dramatically. People using excel tend to be much more deliberate and cautious when creating the spreadsheet because debugging is such a pain, which means they tend to operate at a much slower pace. With programming, you can quickly pound out a script (often without even testing the various pieces of it) because you know you can easily debug the thing afterwards. From my experience, the difference in working styles results in almost an order of magnitude difference in productivity (what would take me an hour or two to create with a programming language could take a day or two to whip up in excel) and even with the extra deliberation/time, errors are still just as prevalent in excel. (And this doesn't even take into account the fact that it is much, much easier to reuse code than it is to reuse a spreadsheet).

As typical for science reporting, there's no link to the paper and the issue of it not being peer-reviewed is buried in a quote halfway through.
The CPI has a number of (serious) problems and I would never suggest that congress attempted to change the calculation for anything other than cynical reasons, but the proposed change would coincidentally be the better measure.

The current method which is often used to adjust nominal expenditures into current dollars is calculated using a Laspeyres index which, year-over-year, does not account for the fact that when prices change people shift their patterns of consumption.

A Paasche index is somewhat the reverse of this in that it assumes that what you purchased last year was the same as what you purchased this year.

The Fisher index is the geometric mean of the two and if you've had a chance to study some of the methods and difficulties of constructing price indexes, it does offer a plausible compromise between the two, allowing for substition but giving some weight to both indices.

However that it accomodates changes in consumption or "substitution" lets lobbies like the AARP exclaim that it hides the case that retirees have to switch from beef tenderloin to cat food when prices rise.

But in actuality it's both a pretty minor change and the better measure of price changes (if the underlying data can be trusted).

Thanks!

Let me start by saying that I'm not asking for or expecting perfect hardware or software. This does not exist. I'm looking for improvements. Sane? Let's start with "sane-er". I linked to the i210 because it offers exactly what I'm asking for: improvement (as you'd expect in 4+ years of development).

The link for the i210 was an overview for general consumption. The 862 page datasheet is here:

http://www.intel.com/content/dam/www/public/us/en/documents/...

The description of the various memory and configuration spaces starts around page 53. When compared to what's available in the 82574L this is clearly a substantial improvement.

However, as I say in my update, we still don't /really/ know why this issue manifested the way it did. Without knowing the true underlying cause anything I offer is speculation, as are your suppositions. With that it is unknown as to whether or not the improvements in the i210 would have eliminated or even ameliorated this issue.

As far as catching this exception in driver software? Possible, but doubtful. Working with Intel last fall they seemed to dismiss this possibility. Current drivers report a loss of communication with the PHY and the adapter seems to essentially disappear from the PCI bus until a full power cycle.

Neither Intel nor my board vendor reported these findings to me until this story broke last week. I reported this issue to them last fall: both of them claimed to have never seen this issue before (or since).

Meanwhile, as I’ve said before, other people have consistently reproduced this issue with different board manufacturers. We are pursuing a second source but I'm not going to be any more confident with the second source if it has 82574L controllers. I can't be certain it's going to be any different.

I'm just as suspicious of Scandinavian comparisons as the next American, but this is not a valid objection. We are specifically comparing the privileges and services that each society provides to its citizens, for the citizens' well-being and that of the society as a whole. To say, "we don't have that luxury" (of what? a "metropolitan" environment? our urban kids do worse than our rural kids!) is to admit in damning fashion that our privileges and services aren't as good as those the Finnish receive. I could understand this sort of whining from Bangladesh or the Congo, but coming from the USA it's pathetic.
A compromised employee machine will always cause problems. (Just look at Google, the New York Times, etc.) We're obviously careful about what goes in email, and I think the open-by-default policy largely makes the security properties of email clearer. (I.e., don't put sensitive material here.)
Hey, I don't have anything to do with the Play Store or the Nexus 4, but I just wanted to say that I'm sorry that you had such a bad experience. My hope is that Google learns from feedback like your experience so that we don't make these kinds of mistakes in the future. But I'm sorry that trying to get the Nexus 4 was so frustrating. :(

"basic compliance is absolutely necessary"

Basic compliance is necessary for what? Here you are, claiming that the goal of school is not to produce compliant people, yet you claim that compliance is "absolutely necessary" in a school. You are claiming that time-wasting assignments with no educational value are a necessary thing for students to work through, because at some point you might be able to teach. How about just skipping the things that you admit are pointless, and just teaching?

"the average student"

If you are willing to acknowledge that some students are different from others, that some students have different needs than others, why not grade talented students differently? If you have a student who has clearly mastered the material of the course, to the point where your assignments and lectures are just wasting their time, why not give them an A and then teach them more interesting / advanced material? Why demand that students who are not in need of your instruction be just as obedient as those who would be lost without you?

We have those, they are called compilers.

"Bugs" are just differences between expected and actual behavior. There is no definitive "right" or "wrong". There is only a matter of correct interpretation.

What you are essentially asking for is for me to eliminate the need for not only your program, but the user using it. That's far from technically impossible; whole industries are built on that idea.

Civil Disobedience 2
Here's my problem.

It works, fairly well. But I spent about 15 minutes doing one panel, trying to figure out the minor nuances. I kept thinking to myself "I could do a whole comic in about 5 minutes in photoshop" as I adjusted the person's location, arm, speech, etc (and that was just modifying the characters that were already in the scene). In the end it was just not worth it in my mind.

Also, imagine creating something like Randalls "Click and Drag" comic (xkcd.com/1110/) -- how would you create all these custom objects in the editor without changing it into something similar to an HTML5 web-photoshop, at which point you might as well do that?
> This is not a problem with using classes or overriding methods, its a problem either with either failure to document behavior on the part of the library author or failure to read documentation on the part of the library consumer.

Missing or poor documentation is a sad reality of programming in the real world. And is the normal state when working on a active project with other developers. This would be mitigated if programmers were very careful about declaring methods to be final if it's not perfectly safe to override them, but most are not that careful, or even fully aware of the issues. And in many programming languages there is no way to declare a method to be final.

> Neither of those is any less a danger in the case here the design of the library involves parameterizing functionality by passing functions around as parameters.

When programming in a functional style, functionality that is not intended to be modified by the client will not provide a parameter for doing so, so this significant source of confusion is eliminated.
Wolfram prefers "Wolfram." Telling.
Yeah, these are very good questions. It's easy to pick an arbitrary metric that seems like it would measure the right thing, but doesn't.

I usually try to stick to the specific phrasing - what is the test that measures your definition of success, such that if the test passes, success is definitely going up, and if the test fails, success is definitely going down?

Even before that step, part of the problem is that we have to have a definition of success before we can determine how to measure it. Ask people what the goal of the education system is, and you'll get many different responses.
Wow - in addition to being useful, this is awesome as a learning tool!
That is very sweet.

In Brazil for every 1000 you pay someone in direct wage, about extra 450 are paid to government (total burden of 1450 to pay 1000 of wage)

Of the 1000 that the "someone" received, about 100 go for your retirement savings, 275 in federal taxes, and about more 100 in other random taxes and fees.

(so yes, this mean that if you theoretically pay 1000 as salary, the person ends with 525, and you pay extra 450 to the government, that ends in total with 925! yay excessive regulation and taxing!!!!)

This seems like a great tool I have been waiting for a while. As I understand, it is rather an IMAP client, but will you store my emails on your servers as well? Or do you only connect to the GMail email storage?

Another question comes to mind: how about mobile? I read more than half of my emails on my phone or tablet. Is lightermail able to handle this as well?
