The upper age limit is 2t-14 (as you note earlier in your comment) rather than the 2t+14 you mention later.

Integrating, you get -20(e^(-0.05(2x-14)) - e^(-0.05(x/2+7)))

The derivative (eliminating the constant) is: (e^0.7)(-0.1)(e^(-0.1x))+(e^-0.35)(0.025)(e^(-0.025x))

Wolfram gives about 32.5 as the root.
You can plot the integral (try www.coolmath.com/graphit) and mouse over to confirm.
A similar thing, but with better integration with C++. Includes exceptions and a full numerical tower:

I think the term always implied people who don't agree with your viewpoint. People in the rarely call their own military "terrorists" even though they are more than willing to cause both terror and massive death.

PS: I would much rather the term not simply mutate into yet another name for evil / bad people, but good luck fighting that fight.
This was posted before I was ready to get it out there, so that's why there is lots of detail and more data missing.

The decision to go back to 'non-clean' was basically to buy us some time to think this through given our newfound insight. Charles and Jan have some ideas that may chart a path out of this mess and I trust them enough to have my interests at heart in it too. The next couple of months will be quite interesting.

That is a possibility, but we would not have gotten to the longer run, now we at least have a chance.

I'm not sure that arbitrary firings for political reasons is relevant, either to the original article or the issue at large.

Are you joking? Cocoa / GNUStep applications have been around for years and Apple has in no way attempted to punish anybody for making them.

GNUstep has already been tracking Apple's Cocoa for years without Apple complaining.

It's definitely true that labor relations gets simpler when you can conscript your employees and place them under an entirely different code of law than US citizens. Maybe we should try that with developers, too. They're getting awfully expensive.
Why You Should Start A Company in...Salt Lake City
There are so many problems with this article, I don't even know where to start:

- never say never

> he is doing exactly what you are doing by hiring him (being lazy).

Or maybe you are not a programmer or can't afford to set up an office etc.

> The people writing your code don’t care about you

And how is this specific to outsourcing? if you set up an office, hire a group of programmers, it doesn't guaranty that those programmers will care about you.

> this will ultimately lead to sloppy, prefabricated, and overall apathetic development

Not if you hire the right people.

> Most outsourced coders are used to standard applications

Correction: "Most coders are used to standard applications"

> 4. Opportunity costs – If you are asking for specific and complex modules then the programmer will most likely bail on your project because he/she is looking to turn some quick money; not make you rich.

This is downright ridiculous freelancers love long projects, it gives economic stability.

> You have forever tainted your startup

This paragraph again is not specific to outsourcing.

Basically this article would be fine if it would say "don't hire idiots to do your code", the points mentioned have nothing to do with outsourcing.

Interesting is a pretty shallow rationale for what's being done. They have an agenda and I'm not going to pretend Wikileaks is some kind of openness nerd savior.

If you are supplying the developer with algorithms that are specific (critical/unique) to your business, then for the avoidance of doubt you should make explicit in the contract that you own the IP for any work the developer does for you.

It's unlikely that anyone would use a developer that they didn't know personally, without a formal contract, for this type of work though.

On the other hand, if you're asking for a vanilla e-commerce site then it's less relevant, the code the developer uses may come from open source libraries, or it may be his that he his re-using, but it probably matters little to you as it's the content on the site not the code behind it that you really care about.

You will always own the copyright on the website, including the design artefacts, unless you are explicitly licensing them.

Ideally you would also somehow get the developer to verify that all the code they are using has a valid licence, as ultimately you're probably liable for infringement. Again, I guess this is trickier to do in a web based developer market, but probably not going to be an issue for a vanilla job like an e-commerce site or marketplace.
If you ever watched a Reagan speech you'd probably agree that "terrorist" has been a pretty meaningless word for some time. The man literally called on group "terrorists" and the other "freedom fighters" even though they were both doing the same things (well, he was paying one group so I suppose that might adjust his perspective).

"I'm both a Lisp and a C++ fan..."

I find that to be very interesting. I spent far too many years working with C++, trying to master all of its nooks and crannies. It was my frustration with the limits of the language that drove me to finally learn Lisp. The fact that for loops always ended up appearing clearer than using STL was extremely frustrating. I'm not 100% sure that the introduction of lambdas in the newer versions of the C++ standard will not fix the problem (or at least help some), but I sincerely doubt that they will be enough. I truly wanted to use STL and the the standard containers, but it always ended up feeling like I was working extra hard to try and "get it right". In the end it was faster just to grumble, write another for loop with an explicit iterator, and move on.

And yes, I'm aware of Boost and the like. I have all the template metaprogramming books you are likely to name. It all still feels terribly unnatural and forced compared to, say, composing a chain of function calls against a list of data in Lisp or Scheme.

That's reaching, private communications can be protected quite effectively by encryption, and having your private communications released to the public means that at least one person who should not have had access to that data get their hands on it.

So only in the case that all those conditions are met and the person we're talking about is embarrassed to the point where they'd rather shut up than speak out (in which case I'd call them a coward) does that come true.
I'm sorry! This is a bug I just can't seem to fix (and it's not consistent either) or find out why it's happening.
I'm pretty sure it's impossible for a human. On the other hand we can do amazing feats of balance that no robot can do, like walking quickly on two legs across an uneven surface. It's all a matter of specialisation.
I've been to a private school where the teachers were unionized. They were with a different union association than the public school teachers. This was in Canada, not in the US but I don't see why it would be different.

Exactly! However there are idots everywhere, and having relatively little connection with the developer breeds more "idiot" behavior than does having a in-house dev.

This should probably be updated to point to the w3 proposal document, but I'm interested. For a while now I've wanted to have this functionality, but short of using flash (or sticking yet another backend server between processes) this has been impossible.

The education problem is compounded by a lack of competition between schools themselves. Children are assigned to one public school, based on residence. In order to switch schools, you have to switch residence. This, along with unions, have entrenched a mediocre education system.

Ask HN: Ideas for Building Critical Mass for Taxi Sharing App
Hi HN - I'm working on a side project (also writing a paper on it for class) to help users share taxi rides to save money/time. It lets users enter their trip information ahead of time and matches users with others who have similar trips (they can also chat and see each other on the map to help find each other). It is a mobile app (iOS now, more later) with app engine on the backend.

Of course, the utility of such an app is highly dependent on the number of users using it (a common problem in web businesses).

I have a shortlist of ideas to help build this critical mass but would love some feedback/ideas from HN users.

1) Look for high travel density areas (high number of taxi departures) and market specifically there. Some examples would be getting airports, hotels, campuses, etc to help market the app (value for them is it reduces congestion is a useful service for their customers).

2) Partner with environmental groups or student clubs to get small armies to market directly to users (goto airport taxi stand lines helping to match users and asking them to get the app)

3) Since this app is about saving users money, one way to encourage usage is to simulate this benefit until there is a critical mass of users. The idea here would be that if you tell us about your trip at least 24 hours in advance and we can't find you a match then we will credit your account with $X. Once you reach $Y, we send you a coupon for a free taxi ride. THis obviously has the potential to be very expensive and a target for abuse so both would have to be mitigated.

4) Viral distribution - push a users trips to their social network to match them with friends with similar trips. While an obvious feature, it doesn't seem likely to work as this probably already happens informally and you need a large number of users to actually find a match.

5) One potential way to monetize this app is to charge a lead gen fee to cab/limo companies. However, we could pass value onto end consumers as a discount on their ride. The idea would be that if you use the app to find a match and book a cab with us, you get a discounted fair (because we sell the lead to a cab company in exchange for you getting a lower fare).

I realize these aren't necessarily scalable marketing ideas, but they do have the benefit of being localized to specific geo areas. This is important as you'd rather have your users in concentrated clusters to improve matching.

I'm not as concerned with monetizing the app (I built it because I want to use it), but ideas here are welcome.

Also, I have a prototype built. If there is interest I can record a screencast demo if anyone wants to see it...

If readability is your goal, the code should be focused on the task you're trying to teach. Code to put the result in a database is ancillary and could be cut, for a positive impact on readability.

I wonder if that was related to "\n", or if the synthesizer intentionally mapped nonprinting characters to sounds (that would seem to make the command set more complicated than necessary, but bytes were precious then so what do I know.)
Depends on what country you (or your money) live in.

In the US has some low fee index funds. In Germany I used an ETF of max-blue.

Just find a low fee diversified index fund, and then get back to your normal work. (Unless you enjoy playing the stock market, than there's nothing wrong with active investment. Just as some people enjoy playing the lottery (only the expected value of active investment isn't as dismal as playing the lottery).) Benjamin Graham's "Security Analysis" is a good primer, if you really want to get into stock or bond trading, or are just interested on an intellectual level. It's a hard book.

Make sure you use a tax efficient way to invest. If you can invest with pre-tax money, do so.
I'm confused. Really confused.

This is why you design the thing, before internal operation. He's working in the wrong mental design language, thinking in terms of how the thing works, rather than how the user interacts.

Is this why so many enterprise apps are f'ed up?
This seems very US-centric. In Sweden there is a union for military officers for example.

And there are plenty of civilian employees working for the armed forces that can join unions as much as they like and presumably cause quite a bit of chaos if they go on strike.

Is the argument that teacher unions should be illegal because they somehow stifle education? That seems insane, isn't it a fundamental right to join whatever organisation you wish, not just the ones the government likes?

And there are lots and lots of countries with teachers unions that outrank the US in various quality of education rankings (e.g. Finland), so it doesn't seem like teachers unions are a big barrier to higher quality education.

But you do have the right to select any school you like here, which is considered some sort of extreme right wing thing in the states as far as I can tell. Although free choice of schools has it's own share of problems...
Feel free to email me! My email is at the bottom of the site or in my profile here :)
If the US did ban teachers and other vital public employees from unionization, there would in fairness need to be corresponding changes on the employer side. Among these could be a law to prohibit firing of these employees except under conditions A, B and C.
He'd have to break it first. From what I get all this stuff was in plaintext, not even the most basic precautions were taken to limit access.

The simplest way is to just make the thing out of metal. Over 90% of metals (especially so if they're easy to extract) gets recycled. Metal recycling is economical and has been happening before the concept of "recycling" was invented.

> After all, despite the massive volume of documents released, there has been surprisingly little material for scandal.

I feel really sad reading this. The impression I've gotten from the media (mostly newspapers, little TV coverage) about this leak is that any and all "issues", "scandals", whatever you want to call them are downplayed, dismissed or worse, not even mentioned. I have the uneasy feeling that had this come to light when Bush was president, the outrage would be massive; now, however, few seem to care and I don't see any willingness to make people care either.

As a sidenote to, quoting: "When your personal medical or financial records can be disclosed at any time, will you still enjoy the notion of “free speech”?" :
The Greek government, with consent from EU, is planning to make any and all citizens' financial records public. The legal basis for this enterprise exists since 1992, and it's only awaiting approval from the DPA (Hellenic Data Protection Authority). I assure you that barring the initial exclamation-filled newspaper headlines, nobody's said a word about this.

So, Mr. Vegter, the people are far too misinformed and manipulated by biased executives to care about their privacy anymore, let alone "free speech". Congratulations.

Currently + is implemented as a special form. You could translate + to operator.add, treat it like a function, and obtain better generality. Also, lambda is not implemented. (The only functions are global ones using 'set'). Lambda is, in some sense, the essence of a Lisp; it seems like a reach to call this a Lisp compiler without lambda.
Yes and no. If you know that stuff you say confidentially could be leaked at any time, you would be pressuring yourself to keep your lips sealed - at least, if you're ethical and care about privacy.

Charter schools have ended this to some degree - in places that have them you can enroll your kids (often for free) in a school of your choice.
