Ask HN: Any other crossfit lovers? We need a better app
The current offering of apps for crossfit is sparse and fragmented, and there's no functionality for really tracking progress or integrating with the crossfit site. Part of the problem is that crossfit doesn't offer any sort of API.. but there's potential for linking back to and pulling data from their servers. A geomapping feature for finding other crossfitters in the area would be exceptionally useful as well - it sucks doing the WOD by yourself! (foursquare + crossfit FTW) I'm happy to work on the UI/wireframes/potential design/use case stories, if someone with programming ideas would be interested in teaming up. (note: crossfit.com is not a web app, a mistake in my estimation)
Honestly, I don't know. But I know a lot ignored it because it said "FREE iPad".
Read the book. It's quite interesting to see how they're presenting themselves to potential employees. Maybe some ideas for any startup who is recruiting?
and maybe a segment on stories that didn't make it to the front page but we think the HN audience would LOVE - I'm sure there are plenty of these.
Or, they're people who are really busy, aren't looking for a job right now but are open to new offers. Maybe people like myself who work in related disciplines and are considering a career change. The iPad is just a way of gaining publicity, and it seems to have worked pretty nicely.

> But individual, selfish agents do not always act in the public interest.

That assumes that "the public interest" is well defined and knowable.

It may be in a very small number of cases but, in general, when someone invokes "the public interest", they're trying to get you to go along with what they want, the "public" be damned.

And no, it's not the frauds who do the most damage, it's the do-gooders, the true believers, by a large margin. The frauds can be bought off.

Ask HN: Which idea to use to illustrate building a startup on EC2? 
I am writing an extended online guide on how to build a startup company from scratch using tools from Amazon and Google, covering EC2, S3, Adwords, and the like.

Any ideas on which startup idea I should use? The idea does not have to be original, in fact it is better for design comparison if there is more than one company pursuing this idea. Also, it should involve some online data storage (so that I can show how S3 is used) and online processing (for EC2).

There's the classic online photo/video sharing app. Anything else?

My bosses just significantly upgraded our hardware, mainly because they couldn't afford raises at that time. We knew that's why they were doing it, but it was still nice to get new machines with big monitors.

That's what I think the article is getting at. Hardware is a cheap way to make your employees a little bit happier, and the employees at least know that you're trying.

I thought this was a great bit on how backwards the publishing industry still is:

Tim O’Reilly, the founder and C.E.O. of O’Reilly Media, which publishes about two hundred e-books per year, thinks that the old publishers’ model is fundamentally flawed. “They think their customer is the bookstore,” he says. “Publishers never built the infrastructure to respond to customers.” Without bookstores, it would take years for publishers to learn how to sell books directly to consumers. They do no market research, have little data on their customers, and have no experience in direct retailing. With the possible exception of Harlequin Romance and Penguin paperbacks, readers have no particular association with any given publisher; in books, the author is the brand name. To attract consumers, publishers would have to build a single, collaborative Web site to sell e-books, an idea that Jason Epstein, the former editorial director of Random House, pushed for years without success. But, even setting aside the difficulties of learning how to run a retail business, such a site would face problems of protocol worthy of the U.N. Security Council—if Amazon didn’t accuse publishers of price-fixing first.
There's always iPad.

Techies almost always consider themselves quite smart. However, a big fraction of them are egregiously ignorant of important technical matters. Security has always been a problem area as far as this goes.

This would be a good topic for interviews!
It depends on whether you want your users to compete against each other or not.

Take in example reddit trying to avoid becoming digg and hacker news trying to avoid becoming reddit, what is everyone trying to avoid? Competition for points and essentially leaderboards.

However for something like games leaderboards are essential as they can provide an incentive to keep playing.
Very stable and fast implementation. Just finished porting a Scala project and the F# code runs around 50% faster on CLR 4.0 compared to Scala on JRockit JVM.
Sorry, I meant to say function pointers. But hey, I'm far from a big supporter of C++. I know its deficiencies very well unfortunately.
This would be a very interesting statistic to gather. I could see it going both ways. Requiring a CC up front might eliminate a lot of "dead weight" who will never pay, but might also eliminate some people who would.

It's a bit of misconception that tax increases that much - as national insurance drops off.

E.g http://www.thesalarycalculator.co.uk/salary.php

(figures in GBP)

30k -> 22.6k (25% total employee tax burden)

45k -> 32.8K (27% total employee tax burden)

90k -> 59.4K (34% total employee tax burden)

135k -> 86.0K (36% total employee tax burden)
Why would people copy a private key around?

Generate the public/private pair on the client machine and the public key is the one you put on other machines to SSH into them.

Let's make a "type the code listings" book for kids.
We went down to the pub this lunchtime and there were a bunch of them there (they were doing a £5-towards-your-lunch-if-you-chat-to-us thing, too). We had a bit of a chat, but none of our company are really .NET/SQL types and their demographic also seems to be way young. That said, I know a few people at RedGate and they're all very happy, and people who use their tools seem to like them too.

Sure, it's a bit of a stunt but, as the guy we spoke to said, it's cheaper to hand out free iPads to a bunch of people (who pass your screener) than it is to pay a recruitment company, and it builds goodwill (amongst the kinds of people who are swayed by a free iPad, anyway).
Like with the whole "sniffing tor exit nodes" thing [1], you do wonder if it's actually the original owners who fails to protect their data, or if it's someone else [2].

I agree - not entirely sure how this climbed up so high on the front page. There are far better resources available, including the jQuery documentation itself, or http://net.tutsplus.com/tutorials/javascript-ajax/jquery-1-4...
Not that you'd want to do so, but if you're inclined to use a pastebin for such things, I have https://privatepaste.com which does not expose pastes to indexing unless specifically requested in the vhost configuration.
They're hoping that the free publicity attracting _good_ developers who otherwise wouldn't have heard about Redgate, will outweigh having to sift through some extra chaff.
I wonder if Apple had an employee "lose" the phone on purpose. This is a great way to stir up some press and give people a preview without being official about it.

I like the new design.
There's a simple reason why machines don't get upgraded every 18 months; employees do not become more measurably more productive. Management caught on to this literally a decade ago - 5 year cycles are fine.
I think it's because stats is usually not personal. When you actually know someone whom, say, homeopathy helped - now that's a good reason to believe.
if you want to set up seamless logins of an account to anywhere from anywhere, you need to copy around both because any node could either be on the client or server side of the challenge and response.
From my last round of job-hunting around Cambridge (about two years ago) I'd say that was pretty typical for the posts they're looking to fill. As with all things, you have to look at the whole package, and Redgate's is pretty good. I guess it's one of those cases where you trade off being amazingly-paid but working 80 hours a week in a job you hate against being less well-paid (but still frankly not badly paid in the grand scheme of things) but enjoying where you work more. It's not often you find somewhere that'll pay you £60k and still let you go home at 5:30pm.

I'm surprised no one here has mentioned what I see as pretty obvious.

There are not a lot of apparent Startup opportunities in the kernel space.
Yeah, unreleased iPhones get "lost in bars" all the time. ;-)
Because you're still in the process of setting up an actually secure SSH in the first place?

If you're serious about security, scp is not secure (open to man-in-the-middle attacks) until you've transferred keys via some other channel or use a PKI that you actually pay attention to.
So, you're saying that people paste their key online so they don't have to carry it around on a USB stick? Wow.
Seems like that's a serious edge case. Most times (IMHO) you'd be going one direction.

And if you do require both directions, you should generate separate keys on each host and just exchange the public ones.
Tips for Successful Self-Learning
What a misery some people are. I think that cheap air travel is wonderful - it brings all sorts of freedoms and new experiences to so many. For the author of this post - the "silver lining" is that people who have taken advantage of this modern convenience have been inconvenienced and shown the error of their ways in some manner. How silly.

I find that fact that it is far cheaper to fly than it is to travel by car/ferry or train is very telling. It gives some strong clues as to the true cost in world resources of the different modes of transport. If flying is dramatically cheaper then how can it be inefficient in comparison to alternate transport systems? The idea that the train is better in some way is not supported by the market price - there is clearly a massive hidden (well obscured) energy/resource cost associated with rail travel.
Flickr was good before, but they didn't make anything more valuable after. I've been using flickr since 05 and I didn't perceived anything valuable in the product after the yahoo deal.
Markets can act irrationally even if the players are acting rationally. This is because of players acting in their own self-interest. For example, if an investment bank takes an enormous risky position that backfires, it may appear irrational. Then consider the massive severance package and/or political support that protects the executive or firm! Now that risky position isn't so risky after all.

I think my point is that "rational" acting is not a clear-cut term that describes a market and its players. Let's take a look at another player, Joe Homebuyer who has access to easy loan money and can buy well out of his price range. Given that home prices had risen consistently for so long (perhaps longer than Joe Homebuyer has been living), at what point does the overvalued price of the house become irrational? Maybe it's when the mortgage-to-rent ratio is too far off, maybe it is some other trigger, but Joe Homebuyer thinks he has protection anyway because he cannot conceive of the possibility that prices will drop. All of his experience shows only gains for this purchase. So, is buying that overpriced house rational or irrational? Seems rational to Joe, but irrational to people with more information about the market.
In that case, use an ssh-agent and agent forwarding. Then you only need your private key on the box you're actually sitting at.

Say what? scp is perfectly secure (not open to man-in-the-middle attack) without transferring any keys or using any PKI. scp (just like ssh) asks you to verify remote key fingerprint on first connect.

I need a decent news site that's not treated as a spam dump by enterprise software companies. Give me a free one of those, and maybe I'll swing round for an interview.
Unless you want to use headless logins...

An example would be a cron job that copies files to a backup server via scp or rsync over ssh. However, this should also be accompanied by host filters in the authorized_keys file to restrict access to specific hosts.

Using pastebin for this is wrong on so many levels.
They moved all of yahoo photos over to Flickr, as well as some integration between upcoming and Flickr. I'm not sure what else they did.
Blind Men and an Elephant- Nature Versus Nurture and Entrepreneurship

Isn't that a pretty broken design? Copying private keys around sounds like a really bad idea.
I can set this up if Gabe wants it. It shouldn't be too big of deal. Gabe, let me know.
This only works if you know the remote key fingerprint in the first place. If you're setting up new servers, it could potentially be compromised.

But that is being ultra-paranoid in my book.

XAuth a useful service with a poor name
That screen will most definitely be 960x480. Apple prides itself on keeping the iPhone dev simple, so the simplest thing to do is simply upscale everything 2x. Apps with old bitmap resources will still look ok and in order to take advantage of the new screen, developers will simply have to update their apps with higher-res images.

Edit: Sorry for the brainfart, I did mean 960x640 (current screen x2).
You missed a key figure though:

60K -> 41.7K (30% total employee tax burden)

There is a sudden big leap (of an extra 1%) in that particular range before it settles back down again.
So whats the attack vector here? You have unknown users private key to a unknown service. Of course you should keep your private keys private, but exploiting this takes quite a stretch.
That's a nice service, but it is still no option for transferring private keys.
In addition, an unpaid internship only attracts students who do not know their own value. The really good ones know they can find a place willing to pay at least some of what they are worth.
I'm glad this article was written. I've found out some of these things the hard way as an introverted geek. Due to my personality and general disdain of meetings, I will probably never go down the management path, so becoming a tech lead is one of the viable options I've taken at a couple places. Let me say that going out to lunch (and beer Fridays if your company allows that) with your team is one of the best things you can do. It helps the team to jell and fosters open communication which is essential IMO.

The Finest Way To Succeed
"I think many interns would be happy if you paid them only a little money."

Absolutely. As a college student, I would have been happy with a low wage; I didn't need to support myself with the internship income. But after working half the day somewhere, it would have been nice to have a few bucks for a meal, and made it feel less like slave labor.

Mostly it would have been the symbolic value, though. The statement that "you're worth hiring, and we're better off for having you here."
well, as I say in the first few lines of the article:

He didn't say it was the right way to do it. He didn't even say what he was describing was a good idea. He just offered an answer to the question, "Why would people copy a private key around?". Obviously, people are doing it for some reason, misguided as the reason may be.
OK, then. I will just say that in my experience, C++ and Java don't have a huge difference in expressibility. What C++ may gain with syntactic tricks, it loses with manual memory management.

Anyway, in the face of Haskell and Lisp, the differences between java an C++ don't look that great.

Yeah, after seeing the post I thought the title didn't make sense either. I thought it was going to be critical of Chartbeat and the title was implying it's as irrelevant to blogs as GA would be to newspapers.. :-)

(But I might be biased as I tried Chartbeat twice - forgetting about it in the gap - and didn't like it either time.)
Doesn't seem like a real counterpoint. The NYT article was a news piece, as such it was descriptive, not prescriptive.

This may vary with the field. I think it's true of say, web development, because the student could definitely work freelance and get both experience and money. But it might not be true of journalism, or law, etc.

Although it's definitely true that by offering money and/or other perks, the company would get better candidates. Think about how easily Google can choose the best engineers, based on their reputation as an awesome place to work. Now think how much lower a college student's standards are for what's awesome - they've probably never made real money. "They buy you lunch every day" would count as awesome, and doesn't cost much.

"They review your work with you every week and help you improve, then write you a good recommendation" would be even better for highly-motivated students.

If a company became known as the coolest place for students to work, they'd be able to pick the best students for their internships, and those students would be more likely to come back to work there, or recommend good people to work there, after they graduate.
