C'mon. PJ O'Rourke? Is that supposed to be some sly, postmodern reference to retrograde '80s culture or just a Yuppie twitch? If that guy had his way, Reagan would still be president, Alzheimer's and death be damned. PJ O'Rourke should probably be the last person on earth you consult for fashion advice, short of the Pope, whose bathing habits aren't available to us mere mortals, but who has at least one die-hard fan left...

In all seriousness, hats are great; like anything else, they'll see a comeback when the pendulum swings the other way. I smoke a pipe and shave with a straightrazor, when I don't have a beard (which is most of the time). I think I'll buy myself a good hat one of these days just to bring it back and prove old PJ wrong.
"I was dazzled by it at Groupon's Google acquisition turndown, and am dazzled by it with Zuck as well"

Clearly the move by Groupon was a mistake. Ok, you want to build a big company and have a vision, etc, etc... Great. Who cares? That kind of money doesn't come along very often — take it and move on to your NEXT great idea. You'll have another one. Millions in the bank and vacations on yachts and private islands do wonders for the imagination.

Of course, I thought Zuck was crazy for turning down $1 billion from Yahoo 5 years ago. He turned out to be right on that one.

It would be rad if conferences hyped these guidelines before talks. I bet at least a few people would get the hint.
How else am I suppose to promote my poorly conceived idea for a startup, without making a comment in the form of a question?

Conferences are supposed to be as much about gaining wisdom as imparting wisdom. Clearly the question part of a talk is the correct form for this two way transfer of wisdom.
Very nice! Thanks for the comment!
It would be more interesting to show the whole crust as a surprisingly small sphere, then.
you guys are awesome!
Its been down almost all afternoon. I first noticed it around 1pm eastern today. Anyone seen anything anywhere? You'd think they would put up a post somewhere about it.
These articles reinforce something that someone told me a long time ago about a study about interviewing.

1. In most cases, the person (or the person in charge, if it is a panel) makes a decision in the first five minutes of the interview.

2. The decision is based on how much the candidate resembles the interviewer (i.e. how similar they are to the interviewer in terms of personality and skill set).
Ask HN: Best way to keep up to speed on a new language/technology quickly?
For those that have successfully learned a new language, framework, etc. from zero to an intermediate or expert level very quickly, how did you do it? I typically learn by experience at work, but I don't have that luxury this time.
Economists pad their resumes too
It seems to me that regardless, you need to still have a CS degree and understand (and be able to implement) algorithms of increasing complexity, even if you're making a CRUD app.

But I agree, these interview posts altogether don't seem to say anything consistent.
You know those signs on the road in Australia that say, "Tired? Tired driving Kills!" --or something like that? You know that law in Queensland where you can't smoke 25 feet from a starbucks? Or the one in WA where if you get two tickets for screeching your tires, they steal your car and crush it? Or the one where you have to spend 30 minutes strapping on a helmet and pads to climb a ladder and fix a roof tile?

Yeah, you guys are really free thinkers. And your kids look great covered in cancer-causing toxic waste wearing stupid ass straw hats.

I believe question askers have OK public speaking skills. Most just lack an awareness and respect for the audience around them.
It might be useful to have spheres of some of the precious metals (silver, gold, etc.) next to the water sphere to help set the frame of reference. I'm guessing they'll be much, much smaller than the water sphere.

The actual amount of gold in the Earth is pretty poorly constrained, because most of it is expected to be at the core.

edit: I found an estimate (http://discovermagazine.com/2006/sep/innerfortknox) of 1.6e15 tons of gold in the Earth's core. The Earth's oceans, for comparison, have a mass of about 1e18 tons.

Before I would deploy this, I'd have to really understand what you're doing with your chef recipies -- I would be concerned that your use of chef might throw my system into a unknown state -- specifically, what are you doing in chef? Are you adding SSH keys in your recipe (I'm not saying you are -- I'm just saying there's a severe lack of transparency as to what's going on behind the scenes, and that could put me at risk if I were managing that type of thing).

Other than that -- cool stuff.

Not any longer. AT&T revised its soft caps in March. For grandfathered unlimited users on a 3G or HSPA+ device, the soft cap kicks in at 3GB; LTE users see the soft cap at 5GB.[0] Provided a subscriber is using the LTE version of the unlimited plan[1], he or she makes out better than the current $30 offering, which is 3GB regardless of device.

0 - http://www.engadget.com/2012/03/01/atandt-announces-throttli...

1 - The same soft cap applies even if a subscriber is in a non-LTE area or using a non-LTE device, but has at some point activated an LTE device. The differentiation is the plan. Activating an LTE device with grandfathered unlimited will put the LTE version of unlimited on the account, even if the subscriber lives in an area where LTE is not yet offered.
I think it's fair to say that if you're stretching yourself, or working on challenging problems, a reasonable amount of time is spent researching. If you don't know how to do something, you research it. Whether you find it in a textbook or on Stack Overflow, it's essentially the same thing.

Unless you think "good" coders reinvent algorithms they don't know from first principles?
This site is a good idea, but right now it's not very good for a REST beginner, as the label "tutorial" would imply. The quick tips are for people who already know REST design. The status codes are for reference only. The HTTP methods are half-tutorial, half-reference, and don't give you any idea of what to do next.

The "eCollege Best Practices guide" under Resources looks good - that's what I want to see from a tutorial. But why is it only in PDF form? You have a website already, and I don't see any tricky layouts in the PDF - why not just put the text in HTML pages? That would lower the barrier of entry to starting reading, make the book easier to read on small screens by allowing you to adjust the page size and font size, make linking to the book easier, and probably have other benefits.
The question of the origin of water on Earth is yet un-resolved, with a contender to the out gassing theory being deposition by asteroids [1]. Even by that theory I believe it was volatiles (hydrogen, oxygen) that were "outgassed" and then allowed to form into H20 in the atmosphere.

That being said, the possibility of large masses of water subducting under the crust and sitting in the lower mantle has been deemed plausible [2](but not probable).

How to Treat the Online Reviews of Earphones
To someone who needs to buy the earphones, how to treat the online reviews is always a puzzle. There are so many evaluations on the internet, so how to distinguish which one is more believable when they are opposite.
The issue is "discovery" of new music. Labels use experts, and the Internet hasn't yet created a way to crowdsource the process. When it does, labels will become unnecessary.

Fandalism could use competitions to select raw new music, Kickstarter could fund quality production, and Pandora could inject and A/B test the candidate songs?

Manufactured stars were natural with broadcast radio. Labels and DJs could A/B test few songs, so they choose artists and songs carefully by a formula. Feedback came as phoned-in requests and sales of singles, heavily biased by the labels' initial choices. iTunes and Bittorrent haven't done much directly to improve A/B testing bandwidth.

If the problem can be solved for music, the experts who choose the movies and shows that get made could be the next to be replaced.
Thanks, I should have realized the FAQ was probably revised over the years.

While I agree that advice is priceless, don't most startups join YC so they can connect with VC's by the end of the program?
FizzBuzz is great. I can stop 50% of interviews after asking it. Amazing timesaver.

It's also extremely depressing.
I wear a black fedora just about everywhere, mostly because I think it looks cool. I later came to discover a couple other benefits, including:

- It's easier for people to recognize you if you have a hat that you always wear. (Conversely, if you want said people to not recognize you, you can take the hat off.)

- It's also easier for people to find you in a crowd if they know you're wearing a hat.

- If you Scotchgard it, it's reasonably waterproof and can keep rain out of your face.

- Occasionally random people tell you, "Nice hat."

For a guy who's only been to one conference, this a fantastic list. Interesting interplay that I noticed:

a) Ask questions that you believe would be relevant to at least a third of the people in the room. and b)
If you wouldn't ask the question without a room full of people present, then don't ask.

are not mutually exclusive, but do tend to whittle your potential questions down to a small set of very good ones.
Just as important, I'd add that about the time that hats stopped being fashionable, the suit, as the regular wear of men in most occupations most of the time, started to end.

I still find it odd to see old pictures from a century ago with everybody wearing jackets, vest and ties everywhere, even in some labor jobs (at least vests)!

Why? Why should the organizers care about the audience members' desire to "be heard"? Having something to say and saying something worth listening to are not synonymous. The organizers' chief concern is putting on a good event. That requires having interesting talks with interesting questions. It does not require giving every Tom, Dick, and Harry a soapbox with which to draw attention to themselves.
It's not just the roof distance .. when driving, it's significantly less comfortable to wear a hat with a (rear or full) brim against a headrest.
Both the State primary schools I went to in the '90s had strict 'No hat, no play' rules. We had to wear a hat to go outside, and I assume other State schools still have the same rules.

The rule didn't exist in high school though, so nearly everybody stopped using them.
Well, yes. The fact that if you walk around with only a t-shirt covering the upper half of your body then people say nothing whereas if you walk around with only a pair of underpants covering the lower half of your body then people say "ugh, good god, put some fucking pants on, dude!"

This is not a random arbitrary social choice, either; if you're showing your underpants then you're not far away from showing other stuff we really don't wanna see. That's why the social convention is that you need two layers downstairs and one layer upstairs to be considered dressed.

If your next question is "yes, but why do people object to seeing strangers' genitals?" then I could point you at some ev-psych just-so stories, but the answer is "we just do, okay?"
I find Googles' invasion of privacy a big turn off. I have long since stopped using Facebook for exactly this reason. I am not quite at the point with Google where I say I don't trust them, unlike Facebook. I regularly check out DuckDuckGo but its search results are not quite there yet for me, in comparison to Google. At this stage the gap is narrowing, both as a result of my increasing concerns over the invasion of privacy from Google and the increasing quality of DuckDuckGo.

It is only a matter of time before I say goodbye to Google forever....
Powershell never really took off except for admins doing stuff with exchange and what not. I'm an iOS developer sitting amongst 20 odd .NET devs and I'm the only one I ever see using a shell.
I think part of being a good speaker is knowing how to handle the - for lack of a better word - hecklers; the people who ask questions meant to show their expertise, or show they know something. A good speaker should be able to keep these people from disrupting what might otherwise be a Q&A session.
meta post

It would be better if people would evaluate ideas in articles rather than use the author's name as a leverage point to launch personal attacks. Several posts here attack the author as being incompetent in various ways and not having had serious experience. Yet a brief review of his resume shows he works at Travelocity, worked at Apple in the past, and personally invented a innovative spreadsheet using a different information organization paradigm that ended up influencing iNumbers. So he's not really the dumbass that some people are trying to make him out to be. It's obvious he's a talented, serious and experienced engineer. There is nothing wrong with disagreeing with his article, but snarky and contemptuous remarks about his supposed incompetency detract severely from points made, making them seem like the critic is an immature schoolyard bully.
> What is the client supposed to do about it?

Um...send a proper request? This seems like a perfectly fine code to me. Suppose you have an HTTP request that takes two parameters and the client only sends one of them. Which of the other existing 4xx codes would be appropriate for that situation? "400 Bad Request" is probably what you'd use currently, but as defined it indicates a syntactic error with the request rather than a semantic one.
Someone should mention Norvig's spelling corrector.

Analogy works best when it's short and pithy. The amount of text devoted to the 'analogy' should definitely not be allowed to grow several times longer than the exposition it's supposed to illustrate. By then things have gone long past the point where useful rhetorical glossing morphs into incontinent self-absorbed dithering.
P. J. O'Rourke is an old curmudgeon, and old curmudgeons give the best advice.
Ask a question, don't make a comment

This depends on the nature of the talk. I've attended many talks which have included "and there's also this possibility we haven't explored in detail" where speakers have been very overjoyed to have someone stand up and say "we looked at that possibility, and found that it didn't work."
I also found that to be true; but Google results are very much superior in my opinion for time being.

But I am not sure what privacy concerns people have, that being said I am not too worried about that sort of thing.
Thanks! I started noticing and thinking about question asking a lot more during academic talks while I was in college. It's fair to say I hate bad questions :)
Presumably you mean that the comparison would be smearing socialists.

For a while I hated my Motorola Defy. T-Mobile was really behind on releasing Android updates, and all the bloatware really slowed it down. Finally, CyanogenMod 7 came out with Defy support, and I was amazed by how snappy it was, and how much longer my battery lasted. My girlfriend's jealous of how awesome my phone is compared to hers, even though the hardware is identical and we're on the same plan.

Starting with the earth's crust [1]: gold is one of the absolute rarest elements there -- at 72nd out of 78 [a] at between 1-4 parts per 10^9 (mass). The volume of the crust is on the order of 10^10 km^3 [2][b], with a density around 3 g/cm^3 [2], for a mass of gold on the order of 10^11 tonnes. Being extremely dense at 19 g/cm^3 [3], this would fill a compact sphere on the order of 1 km radius.

The mass of the earth [4] is about 200 times more than the crust -- almost 10^22 tonnes -- but the elemental composition of the core is unknown and very different from the crust. It's likely to be highly enriched in gold relative to the crust, because of gravitational separation (heavy metals sink down). Extrapolation from crustal abundance would give 10^13 tonnes, whereas one geologic estimate [5] gives 10^15 tonnes in the core alone -- a sphere 30 km in radius.

[a] excluding short-lived unstable elements and noble gases

[b] roughly, ~40% of the earth's surface (~5*10^8 km^2) is continental crust ~50 km thick

-1. What's the problem with safety laws, and what do they have to do with free thinking?

It's hard to drive when you're tired.

Not everybody in Australia appreciates cigarette smoke.

Most people here don't like hooning, but "they" won't "steal" your car for it. It might, however, be confiscated.

I don't know of the law at home, but workplace health and safety is taken very seriously here. Not wearing safety gear can get you and your employer in quite a bit of trouble.

Try to be a little more constructive instead of mocking Australians.

Edit: The smoking law really is fantastic by the way, when people obey it. As a kid, I remember having to walk through 20 metres of cigarette smoke to get into a shopping centre. It was putrid. I don't mind people smoking, but the smoke buildup outside shops wasn't good.
...I was tempted to relay the story of the best bug I ever found, and realized that it literally boils down to exactly what you said-a missing comma in a vendor's library. Wow.

What made it fun was that it was a SAS program (which I knew) with extremely complex, 5-layer deep macros that called VBScript (which I did not know) all over the place. Debugging stuff in a language you don't know under a tight deadline-that's a thrill!

We use gitit [1]. It supports a number of syntax formats, including Markdown. It supports a number of revision control systems to use as the file store, such as git. I very rarely use the web interface, as I prefer to use the wiki from the command line, using vim for editing. Use of git also allows team members to easily clone the repository and use it even without access to the server.

Note that you can also edit text in Firefox textboxes with the editor of your choice using the "It's All Text!" add-on [2]. I have my browser configured to use gvim, so I can use vim to edit everything from emails and wiki content to this HN comment. :)

I have never understood the idea that only "objects" can have value.

1) I'm paying for a formal education, not the books and the audio of the lectures. Those are often available for free, but the formal seal of approval of a university (not the sheepskin + ink) has market value.

2) I pay for The New Yorker, not the pages it's printed on.

3) A startup pays its programmers for software, which is really just ideas.

4) A company pays for the design of its building, not the drafting paper and pencils.

5) A company pays a manager (at least theoretically) for leadership, not for the transferring of ink to post-it-notes and calendars.

6) Millions of people pay for iPhone apps, which are not physical goods.

7) I'm paying (through insurance) for medical advice, not the negligible fraction of square footage I occupy while sitting in my doctor's office.

Buying recordings is a voluntary transaction. If you don't find them valuable, don't participate. But you are still no more entitled to the sound of an artist's voice than your employer/customers are entitled to the value you provide.

Open Source is cool. Public broadcasting is awesome. Band Camp is amazing, and I agree the mainstream record label cartel is nasty. I hope we move away from it. But just as hating Walmart doesn't make shoplifting okay; disapproval of the music industry doesn't make piracy okay.

Yes, the witch-hunt is too much, but wherever did we get the idea that intellectual creation shouldn't be worth anything?
