Measuring RF and presenting it in a way a normal person can understand is difficult. I've had first hand experience trying to explain to customers that a 0dB signal is not a problem -- in fact it's ideal in our system, or that there's such thing as too much signal, or that signal quality alone isn't a very good indication of reliability/speed without taking into account other important factors such as SNR or real bit error rates, or that a ~4dB signal range swing due to thermal conditions alone is completely normal. In the wireless world you have to represent all this in a little 20 or 30 pixel wide meter.

A better method than the traditional 5 bar icon meter would be a status icon that could show signal strength, signal quality, and also take into account other experience factors like latency and speed. To you could have 5 orange bars showing strong signal while also acknowledging there was some other factor causing less reliability such as SNR problems or channel congestion. You could have 3 green bars showing good RF and network conditions. More accurate but we'd have to ween people off the old system. Ideally you could the choice in your settings for a basic or advanced meter icon.
Some of the more interesting data is when beginner and advanced use of a feature is similar, but intermediate use is way different. Scroll vertical up is 16.7 and 14.4 for beginners and advanced users, but 54.9 for intermediate users. So beginners don't scroll up and advanced users use the page-up key? Reload is similar, beginners don't reload as much as intermediate users and advanced users use F5.

Harder to explain is why location bar clicking goes down once users become intermediate, and then goes back up when they become advanced users.
You just need to develop some sort of "liquid battery" and pump it in some sort of receptacle, or tank, in the car.
Um, I like my Bookmarklets, ok? I'd be lost without the delicious bookmarklet.
I thought the right face was more attractive - it looks "warmer" (nicer, friendlier) than the left one. I must be doing something wrong, like preferring women with whom I would like to be friends. ;-)
Yeah, but more like a thrower than a distance runner.
thanks for sharing that, it helped to find this name origin:

"Revlon was founded in the midst of the Great Depression, 1932, by Charles Revson and his brother Joseph, along with a chemist, Charles Lachman, who contributed the "L" in the REVLON name."

signal strength is measured in logarithmic units, not linear.
Yeah, you definitely have a point there. While many problems have a high degree of inherent complexity, there are plenty of others that don't need to and that have features bolted on left and right to appeal to every possible market. And it's definitely true that big companies hate making these sorts of decisions, because it's expensive and time-consuming and difficult to undo.

One reason a lot of enterprise software gets bloated is that, in order for the market to be viable, it's hard to just target a single niche, so you end up with a superset of features so that you can sell the same market to customers with different requirements.

Even in the best case, though, system specialization can be a knife-edge that cuts both ways. Many of our customers, for example, are in a trouble precisely because they have way, way too many one-off systems. They have this system over here that does just workers comp claims, and another system for handling personal auto claims, and another system for tracking notes, and an entirely different system for first notice of less entry versus for actually handling claims, and then most of their commercial business is in yet another system, except for some specialty lines that are elsehwere. Then they have five different policy administration systems, and a couple of billing systems, and each of those talks to a different document production system . . . it's a total nightmare.

So sometimes the choice is between having 3 complex systems or 25 purpose-built systems and a total integration and user training nightmare, and both options suck.

Basically, as soon as you have a bunch of data that you need to do a ton of different things with, you're left with two bad choices: you can create one really complex application that tries to do everything, or you can create a bunch of smaller applications and end up with a bunch of complicated integrations. Fundamentally, as soon as you have complex data that you have to do a bunch of stuff with, you're going to be in trouble no matter what you do.
1.9.1 isn't supported: http://edgeguides.rubyonrails.org/3_0_release_notes.html#rai...

That said, I am using 1.9.1 in production (non-Rails project) and have had almost no issues so far, apart from a few libraries that had to be updated, but that was mostly minor issues (e.g. #methods returns strings in 1.8 and symbols in 1.9).
Historically, battery tech progress has been depressingly slow. Slow enough to be the primary limiting factor for a lot of technologies. The vast majority of progress has been in reducing power consumption rather than increasing power storage.
Use require_relative if you want to require files relative to __FILE__, that way you don't have to worry about $LOAD_PATH and keep your sanity :)

"We do something similar. We call it “clouding.” Right now, for example, we’ve sent out the following messages about iPhone 4 and the antenna issues:

1. All mobile phones have this problem.

2. Our mobile phone does not have this problem.

You see how this works? These two statements cannot both be true.

Yet we’ve said both of them. And now you don’t know what to believe."
Can you describe how you envision this working? Why would you choose to use a client that correctly implemented the drm features? How could a free/open source client even accomplish the drm?
One of the reasons the government fails is because it never wants to change a policy once set, and doing that when failure become obvious to all often takes decades.

Um, does your cash lower your tax burden? You should look at your marginal tax rate. I'm personally pushing 40% marginally, which means that any "perks" that the company can offer me which don't show up on my final W-2 are worth almost twice as much as if I'd had to pay for them out of pocket. Once you reach a certain salary level, you're wasting money not negotiating down your salary for things you value more.
A bachelors degree in CompSci, based solely on the requirements drastically reduces the number of candidates who can actually produce results, but chose not to apply because they feel their lack of qualifications will immediately disqualify them (or some will just lie). On the flip side, it might give them some outstanding candidates who have actually gone the distance and can think proactively. That's not to say people without BA's can't do the same. It's a dual-edged sword for a position like this.

Preface: I am a virtual recruiter.

Employers have found success at shrinking their candidate pool when adding even the slightest text in their copy when it comes to ability requirements. Some of my early jobs required skills and qualifications I never achieved or experienced; but I landed the job because my resume was slammed pack with solutions, and details of problem solving (as opposed to creating a resume that told the hiring manager nothing more than what my daily tasks were)

Dropbox may have plans to groom this web engineer into a larger role within the organization, and that often works well within organizations; providing the avenues for upward mobility. However they'd do themselves, and their potential job candidates a favor by indicating this up front instead of effectively discouraging great prospects the opportunity to apply simply because of a degree requirement that will lead to a career trajectory that far overshoots roles and responsibilities listed.

A four year degree in computer science for someone to be a web developer and an end-user support technician is asking for overqualified candidates who will very likely get more attractive offers later on down the road. But that's not to say Dropbox wont make their stay worthwhile, overqualified or under.

Shameless: I'd love to reach out to the DB team and talk about this.
At any rate it violates Facebook's terms (http://www.facebook.com/terms.php, 4.5): "You will not use Facebook if you are under 13."
at the risk of HN turning into online gossip forums ... could we stop with the "you don't need no damn degree to do them codin' jobs" comments? if you truly feel that way, then on your own company's hiring webpage, you don't have to put that as a requirement. but obviously the dropbox folks decided that it was a reasonable requirement, for one reason or another. we can debate the merits of that decision all day and night, but to ad hominem one of its co-founders doesn't seem constructive

Edit: thanks for taking down the comment i was referring to
n = 2048
2048 times:
n = n*2^n
Now we use the fact that we only need the last 10 digits.
n = 2048
2048 times:
n = (n*2^n) % 10^10

CHEAT! x^y mod N is not necessarily the same as x^(y mod N) mod N.

In this case it happens to be true, but you really should explain why.
A slightly different version:

function countdown (num) {
for (var i = 0; i <= num; i += 1) {
setTimeout(function (i) {
return function(){ alert(num - i); }
}(i), i * 1000);
}
}

countdown(5);
I think the parents were alluding to the unconscious deduction many many people have been shown to make- that more attractive people are smarter.
Remember when facebook introduced the option to show limited profiles to certain people? I liked the concept but it was clumsy to use and it was clear to the other party what I was doing.

In fact, the reason I switched to facebook originally was it looked like a myspace for just my school friends.

Getting this right would be a big selling point for me.
It's odd to see my verbal tics rendered faithfully to text - the number of times I say "sort of" and "kind of" in this is quite scary.

What about relative application numbers? These things are partially self-selected. The first thing that occurred to me when I read the main observations in the article* was, "What if the proportion of girls in the programs is higher because more girls (or parents of girls) want to participate in the programs?" Wanting to participate (and especially having parents who want one to participate) would not necessarily be correlated with intelligence anyway.

*- That 1) gifted and talented programs in New York are tending to have more female students, and 2) this cannot be explained by suggesting that there are more gifted and talented girls.

It's really not very close. The "outliers" are things like "execute" where men dominate more than 2:1. The only places where women have more of are clerical and sales positions.

And really the real question, if you're interested in workforce data is money. There's a huge gap between men and women:
http://usgovinfo.about.com/od/censusandstatistics/a/paygapgr...

Now of course the standard reply is "they work different jobs". And that's true. Jobs men work tend to pay more. Why is that? Who knows. And if you look at the historic pay of fields like psychology, once dominated by men, it used to pay very well. As women began to play a large role in the field, pay dropped. Did men leave because pay drop or did pay drop because men left? No one knows.

But I still believe my fundamental point. If you're a man and you're not doing as well as you like and it's because you think women have done you in, I just personally have a low opinion of you. Not that you'd care about my opinion, but that's just my take. And I'll raise my kids, to the best of my ability, to not believe that they can't get a fair shot in life because women run the show.

From what I've seen extended life batteries for phones tend to be 100-200mAh larger than stock batteries. So I think that would work out to a ~10% improvement for most phones. It really depends on the capacity of the OEM battery. I remember seeing a 2000mAh+ battery for the EVO which would be nearly a 25% improvement over the stock battery.
An Umbrella is what you need
I think it's better to learn how to make a realistic empirical estimation of whether you're "above or below average" whatever that means in context, and recognize when it doesn't matter at all-- like with driving skill-- than it is to just assume you're below average. You can assume you're a bad driver or assume you're a good driver and it won't likely make any difference at all in your life.
Speed dial is less useful when it doesn't consider context.
De-skilling has nothing to do with that, it has to do with changing jobs so that they require less skill. Assembly line factories are an example, they were an efficiency improvement over individual craftsmen that not coincidentally required much less skilled labor. See http://en.wikipedia.org/wiki/Deskilling and http://www.google.com/search?q=deskilling+programming and http://www.amazon.com/s?index=blended&link_code=qs&f...

Even then, in knowledge work you're obviously going to care about skill.

(Sure wish I'd believed a book on this subject (the deskilling of programming) that I read in the '80s; knowing what a recipe for technical failure it is I didn't. Unfortunately all too many suits believe it.)
I think it was meant to be tongue-in-cheek.
having a general controversial topic would get lot of discussion

I can make some similar absurd claims

"consulting does not work" , they don't tell you what you did not know, right?

"medicines do not work" we know about placebo effect

all this is absurd, insult to our intelligence
They call this a challenge? Closures and a nested unordered list CSS menu. Wow!

> the mental energy of learning PHP is not worth it either

You probably already know PHP. It's so much like many other languages and it doesn't require much knowledge to get started. Many of the "gotchas" about PHP are more academic than practical and if you are ignorant about these things then you are more likely to do it right. Some of the horrible stuff, like huge body of non-namespaced functions, is pretty easy to search though and then use without a lot of knowledge overhead.

I actually write very large business web applications in PHP. Crazy? Maybe. There is a bit of a sunk cost here, when the app was started most other solutions were pretty immature. However even with potentially "better" options now, PHP isn't going to burn down the house.

"Women with smaller feet have prettier faces, at least according to the men who took part in this study. So do women with longer thigh bones and narrower hips, as well as women who are taller overall."

Seems odd because short women usually don't have large feet (at least from my experience).

My wife is only 4'11" but has small feet.
Well, num is the stable variable, it's i that's the issue.

Grokking what's going on here is one of the more important parts of using closures without introducing unexpected bugs.
It's funny how things have changed since when I was a kid in the 1960s. Back then, attractive people were generally thought NOT to be smart because they were more social than unattractive (average-looking) people. I hold this belief to this day and in my personal life it has been rarely wrong.
It's actually an awesome idea. But to test it's viability why not use some live video tool or even a youtube playlist for a start. Later on if it works you could go around and get some funding to start a tv channel (I don't know about the amount of money needed to start one. I assume it's huge).

But since Google TV is coming, you could target it and keep it as just a youtube channel.

Less ad time please. Some people hate tv just coz of irrelevant ads. But you could be the first one to solve this problem again. You could ask for the viewers profile or monitor his twitter or social network statuses and relay related ads but to keep up the quality keep the relativity coefficient high. Like consider only data that's an hour old :)

So if you feel this is a nice idea. Go ahead and start it and I'll be among your first batch of viewers if you get quality stuff.

P.S: You could also just select good tech interviews/videos/screencasts for a start :)
I think you misunderstood my point. I don't think they're getting an imbalanced education. And if they do think that, it's not because they are. But it's because they're whiners or losers.

A lot of people get imbalanced education. Blacks do. Overweight kids probably. Ugly kids probably even do. Men don't, at least not that I've ever seen. I think it's literally 10x more likely that you get discriminated against because you listen to Lady Gaga than because you're male.
22 year old gay male here--I chose right, left, right, right. For the women, I thought the right faces looked happier and more engaging. I was pretty confident in my answers except for #2, the first male in the series. I think the transparent hair across the forehead was skewing my reaction.

If heterosexual males and females preferred the left images far more often, it's strange that I would have chosen the right for both. I wonder if these results are typical for my subgroup, and if so, why?

Gotta love having hardwired sexual preferences for a non-reproductive orientation! It's like asking whether you prefer carburetors or fuel injection on your bumper car. :)
> Do you actually know any nurses

I do. My best friend is an ER nurse.

Cushy in terms of compensation and benefits. Not in terms of work being easy. Please read the post that I was replying to.
> diamond vapor-phase deposition

I've seen this repeated at a lot of places, but I'm quite sure this should be "diamond-like carbon" and not actual diamond deposition.

Even then, I could not see any source for this, besides one blog comment somewhere saying the screen coating "may even be" DLC. All articles on the topic made no mention of the composition. Where does this information come from?

Not that it matters a whole lot, but I find it annoying when people repeat technical information carelessly. Even to a layman (and I know nothing about chemical deposition), doesn't "diamond vapor-phase deposition" sound fishy?

Let's say I told you that one of these two women had acromegaly. Which would you pick? The one on the right, most likely. She would also have large feet due to her acromegaly. I suspect that growth hormone (not acromegaly per se) is the link that explains their findings.
None of the things you say that are well established are actually so. Even things like intelligence are still widely debated (the actual definition, much less distribution of it). And societal progress has everything to do with moving the center mass -- not with outliers. But I don't claim that this to be well established.
> How do you incentivize the good ones to work for you?

Easy. Instead of giving the programmers managers, put the programmers in charge of their own projects and give them administrative assistants to handle all of the non-programming and non-decision-making parts of the job.
Launch...but don't blow your wad on marketing until you think you're ready. If you're not confident in it, I'm not sure how you're going to sell it. A small launch within your network could get you the feedback you're looking for.

Don't beat yourself up about Blippy, gdgt, and Swipely. What did they do right? What did they do wrong? What can you learn from them (and on their dollar)? And -- are they REALLY your competitors?

Two last comments. If your design is on the level of your blog design, you'll be fine. It's really clean with clear and concise messaging. Also, have you considered the widening "products you love" into "things you love?" I'm being selfish, but I'd love to be able to follow new "products" from "things I love," like bands. Forget that last thought :)
This is an effect of the lighting. The picture on the right has much better lighting; it's almost textbook portrait. The compositing messed up the lighting in the one on the left, which makes the features look muted in comparison.

My guess would be that the pictures that made up the right-hand composite were more consistent. Either the faces were more consistently in the same place, or they consistently had similar lighting.
Anyone can enlighten me why I keep seeing Zed Shaw being mentioned on HN compare to other star programmers? He appears to be the superstar among all star programmers. But I checked his wiki, and I thought not many are using mongrels nowadays.
Yup, that's the apple design philosophy right there.

The example in the article is that one gives tests which measure a combination of intelligence and the ability to sit still for long periods.

Since young girls have a greater ability to sit still than young boys, they score higher.
Are either of those people core members of the party or are they just random people posting on a forum? And while I certainly agree that 9/11 conspiracy nutters and nutters, they seem to quite evenly distributed across the political spectrum. All parties have their crazies, and judging a political party as whole by their most "out there" members is never good way to foster intelligent debate.
yeah, that's a whole other big debate within academia :)

but if you can make your technical reports and white papers public on your website, that could really help out people working in related areas.

Edit: i agree that if you're running a company, it's probably not worth your time and effort to try to play the academic peer-reviewed publishing game; the benefits to you aren't really that great (besides a bit of PR and connections with academics) ... if you want to share technical info publicly, putting it on your website and then letting Google + Google Scholar index your PDFs is far more effective :)
