Indeed, there must be other effects, perhaps more important than the 'golden football' zone, that explain these loss-leader deals.

Almost any business should be willing to lose a little on product if that loss displaces more in other promotion/customer-acquisition costs. A business would be more willing to do so if they're sure the cost is reaching new customers. Perhaps that's an important part of the Groupon secret sauce -- the purchase of the 'coupon' with credit cards that provide a relatively strong identity signal. That could be used -- eventually, at least -- to target future promotions to unique new customers.

Does anyone know what sort of data the business gets from Groupon? Have any businesses offered repeat Groupons that aren't available to people who bought the first one?
I don't see why this is hacker stuff, but thanks for sharing.
The review is good and DDG is great but the site itself really puts me off and makes me unable to take the information as credible.

It's unlikely to be faster. I can pay with cash or credit card in much less time than my iPhone takes to get a GPS fix & 3G connection indoors.

Also, credit cards are very reliable. I've had mine fail (mag stripe wear, etc.) maybe 3 times in 20 years, but even then it's still usable the old-fashioned way. My iPhone fails (low battery, weak signal) at least weekly. Being occasionally unable to pay is a Really Bad Experience that users won't forgive.

Slower and less reliable. I predict it won't take off.
I wish them well but funny things happen to community based sites when the motivation is purely financial. Once you make it all about the money, then it's only about the money. As such other niceties tend to fall by the wayside as you end up with, well, Johns and providers. I can't see it getting a good reputation, but that's not necessarily an impediment to making a profit.
The ability to communicate well, especially in writing, is important unless all you ever do as a programmer is work alone, never interacting with others or contributing to them. You'll use writing skills to communicate your ideas to your peers and management, and to document your code coherently.

An English degree will do more to teach you about communication than a Comp. Sci. degree. Unless you go on to graduate-level work, in which case you'll probably learn the art of writing completely incomprehensible literary criticism. (e.g. How To Deconstruct Almost Anything: http://www.info.ucl.ac.be/~pvr/decon.html )
This alone is reason enough for me not to use it. I'd much rather have a pre-paid system to replace cash (< $500.-). For larger purchases I'd still use my card.

Heh, nope. I thought asking for money would only complicate their adoption of my idea for cleaning up the DRM integration process. I'm just trying to save the world from some terrible software here, remember (and trying not to create a bigger mess in the process).
If you look at the Django core developers almost none are CS degrees, on the other hand Journalism, English, and Philosophy are all represented. I'm a CS student, however I don't care about my CS courses really, if you're passionate about programming (and some CS concepts) it's not terribly difficult to go far on your own, OTOH in life you rarely get the opportunity to study things like ethics, bioethics, or War in Afghanistan in an environment that seeks to further debate, discussion, and analysis.
Also problems with entering in the amount you are paying them instead of that being automated. What if you mispress and over/under pay by a cent, a dollar, 10$...?

The trick for any service like this is mass adoption. The service needs to be available in enough places so you don't need to carry your credit card. That seems unlikely.
It's arrogant how he confuses anti-intellectualism with anti-academicisim. It's dishonest to ignore somewhat sharper criticisms (is it really a worthwhile intellectual pursuit deserving of public funds to write up even more analyses of Walt Whitman?) and brand your opponents as anti-intellectual.

He also characterizes this article (http://chronicle.com/blogPost/Do-All-Faculty-Members-Real/25...), "Do All Faculty Members Really Need Private Offices", as "anti-faculty", though my reading of the article doesn't lend itself well to this interpretation. (Let's take as given the obvious joke here.) Even on the surface level of treating private offices as symbols of prestige and status, it's rather disingenuous to claim one's profession is under attack by the mere suggestion of abandoning their private offices when many if not most white collar workers don't have private offices in the first place.
It looks like it's "operator billing" and Bango seems to charge a $500/mo fee for it. Thanks for the tip though, I'll keep searching.
Unlimited private repos for free? That is mighty impressive, and stacks up very well against github (especially since I prefer hg over git).
Steps to Bootstrapping Success
I agree that design shouldn't be the focus if you are at the early, bootstrapping stage. You should instead focus on user traction and shaping your product based on user feedback. You can always work on the design part later on.

That said, for a consumer facing product, user experience and design does become important after a point - but it need not be your priority at the very early stage.
I'd say getting an occasion to use hg is just icing on the cake.

It's not just db queries though.. it's also things like 3rd party API calls (S3 for example).

Basically anything where you're blocked waiting for a response you could be busy doing something else.

Synchronous APIs are kind of wasteful in a lot of cases. Node.js does a good job of this by using async APIs.

It's a tradeoff. But the extra complexity can be worth it if it means your pages load 2x faster.
And of course, sunlight has a wide range of wavelengths and it's almost impossible to convert >1000 nM light to electricity, so you can't get close to 100%.

The problem with current cells isn't efficiency but cost. 5% efficient cells that were cheap (including mounting & protection) would be a breakthrough.
Fair enough, maybe the investors told them not to generate cash flow. In which case, the investors are twits and deserve to lose their investment. My point is, whoever made that decision has been hitting the silicon valley kool-aid way too hard.

(Do you really think I'm saying they are responsible to my opinions? You seem like a smarter guy than that.)

I do have strong opinions about the right way to borrow money from other people:

When someone like Xmarks.com flops, it makes startups look bad to the 2 million users who are going to think twice about storing their data on someone's servers. It makes startups look bad to people who would like to make a return on their investment.

You can disrupt and revolt and rethink and metaprogram all you'd like, especially if you're sitting on VC funding. You can call cashflow an "existing business structure", but at some point, eventually, I think you need to charge something for something.
Make sure you're prepared to lose your camera and get roughed up a bit if you decide to do this (which is admirable). In my experience, cops have no patience for people who assert their rights as citizens.

Many police cars nowadays are fitted with front-facing video cameras. One sage piece of advice from a friend of mine is to:

* be extremely polite and cordial; "How may I help you officer?"
* respond requests to be searched with, "Sir, I don't consent to
any searches"
* When you step out of a vehicle, assume the position: legs
apart, hands behind your head.
* Politely ask, "Am I free to go officer, or am I under arrest?"
(repeatedly if necessary)

The point of this is to ensure that nothing you do can be possibly interpreted as an act of aggression by the officer, while asserting your rights. The police camera will show you in a pose of total submission, and any aggression on the part of the police officer will be unjustifiable.

The cop will be annoyed, but he won't touch you, and if he does, you will be vindicated. Your camera footage, OTOH, isn't guaranteed to survive a run-in with the cops (this happened to a friend of mine), and any natural reaction you might have to your camera getting snatched from your hands can be used as an excuse to whip out the tazer.

Remember HNers, the job of contemporary police is to arrest you, not to "serve and protect".

It'd be nice to see a more systematic review comparing the search engines head to head on the same set of queries or tasks. So far the reviews here seem pretty unscientific.

Also, does anyone know if BOSS is now serving Bing rather than Yahoo results after the switchover? It would seem kind of bizarre for Yahoo to continue serving its own results just for this one property (unless they're serving stale results). In any case, gaming at aimed Yahoo or Bing is going to be an issue for anything built on top of them (although DDG of course is free to do its own extra filtering).
Translation: Dear California FTB, my move had absolutely nothing to do with tax avoidance on a cash windfall and I really am a Washington resident. I had NO idea we were being acquired when I made the move 4 months ago... I'm as surprised as you are. Seriously. For reals.

This is actually more legitimate than it sounds. My family's business (www.seliger.com) does grant writing, and my parents really wanted to move to L.A. from Seattle. But they moved to Tucson (where I'm in grad school) instead, because of the cost of housing and the tax situation. Their thinking informed this comment: http://news.ycombinator.com/item?id=1711350 . WA State is contemplating an income tax, which to me sounds like suicide and idiocy because Seattle's biggest advantage over CA is not having an income tax.

In any event, none of my family will step foot in CA for business because of the franchise tax board. But a lot of our clients are there, so every other year or so we'll get a nastygram from them, which requires that we reply and say, "We have no physical presence there, so fuck off."
then how can California do anything?

There are probably rules about how long you need to be there to establish residency. And the franchise tax board is notoriously nasty. I remember reading an article about how they go after athletes who play games in CA (read: all of them). So if you're a basketball player and you play the Lakers, if you earn $200,000 that night, CA wants $20,000, even if that's the only thing you've done in the state.
Idiomatic, no (agreed). Very readable, yes (I think the style was intentional). For tutorials, I generally implement everything myself as part of the learning process and avoid source copy-pasting. So I wasn't irked but YMMV depending on learning style.
Anyone have a nice summary? I don't have time to watch the video now.
Incredibly obvious. In humid areas, air conditioners condense a large amount of moisture out of the air, which absorbs a huge amount of cooling capacity. Water has one of the highest heats of fusion (energy given off or absorbed during change from gas to liquid or vice versa). This is the exact mirror of why swamp coolers work in dry, low humidity areas.

I hadn't considered the effect on my reputation at all.

So, forward simulating (and embedding my sentiments as a measure of my ease of sleeping):

Case {they implement it any nobody learns of the exploit}: I'm remembered as the one who stood up to help reduce friction to new apps being listed. They keep me as a positive point of contact for future design changes. I feel good about baleeting bad software design. Reputation improves, presumably.

Case {I don't tell them about it, they implement it, and somebody turns the conceptual exploit into a real tool after deployment}: The company company loses, consumers win (yarr). The company (and every company they swap stories with) decides never to deal with me, if they decide to pin it on me as intentional. I feel good about baleeting bad software design as well as demonstrating the counterproductiveness of DRM (albeit in a contrived way). Reputation declines, conditionally.

Case {I do tell them, they continue anyway in the name of reduced friction}: They take a calculated risk and own the result. Yay for improved design, but hard to forward simulate any more. Reputation unchanged-ish, regardless of whether the concept is exploited or not.

Case {I do tell them, and they decide to quit the project and keep their old solution}: They feel less receptive to future requests in the name of reduced integration friction ("ya know, it might have a flaw!"). I don't list my apps with them, and I hope that others don't either. Reputation unchanged. The concept of third-party-android-marketplace's reputation (and indirectly Android's)? Decreased relative to potential.

By this, non-exhaustive, in-the-reply-box analysis. It sounds like I should tell them, but somehow do it in a way that doesn't talk them out of it. Best option so far, but somewhat hard to enact.

Btw, I'm not a professional software consultant.
He posts these things all the time for some reason, all to the same website. People have asked before how it has anything to do with "hackers" and to my knowledge there haven't been any responses from the OP.
This was the email I got from Bitbucket:

"Because accounts with 5 or fewer users are free, we will be canceling your subscription and moving you to the free plan (you will be notified by PayPal that your Bitbucket account has been canceled)."

Not sure if that means you'll get your money back, though.
I'm guessing you will lead the development team, so anything in the mid/high range would be appropriate.

Anything that requires a lot of writing would probably do that - you would likely have been as well off taking history. Writing is a skill - the best way to improve your writing is to write, a lot, and hopefully have it criticized by competent writers.

Oh, I know about the Ruby ecosystem. Having to rely on multiple versions of the same library is a bug, not a feature. People do it because the tool lets them, not vice versa.
Ask HN: Why are web startups slow to expand abroad?
When Yelp realized that Europeans may want to rate small businesses as well as Americans, they were confronted with Qype, a fairly direct knockoff started in Germany about a year after Yelp was founded. Because their business depends so heavily on how many reviews you already have (http://goo.gl/ykXu), it'll be hard to take them on.

So Yelp missed an opportunity somewhere during year one, but hey, it happens. They were busy and you can't do everything at once.

What strikes me as stranger is the businesses that have existed for several years, but still don't look across US borders. When I wanted to have some copies of my thesis printed, bound and shipped to Amsterdam, I was surprised that Lulu wasn't set up for it (they shipped from Spain, slowly and expensively) and there was no local equivalent in sight.

All right, all right, setting up a supply chain for mailing physical widgets in lots of confusing little European countries is hard. So let's look at a business that deals in purely virtual goods: Wufoo. I can't find a Wufoo-like thing that'll speak Dutch to me. At all.

Now you may object that Wufoo takes payments, and figuring out how people in lots of confusing little European countries like to pay their bills is not easy.

Which brings me to the last category: web startups that provide some really cheap service or content and that fund themselves largely by ads, or by the expectation that some large company will buy them out and figure out a revenue model later (if ever).

What do people in The Netherlands, to come back to my small but fairly internet-savvy home country, tend to use for small-time blogging? Blogger? Wordpress? Nope. Something called web-log.nl

Now don't get me wrong. I respect the entrepreneurs that started web-log.nl . They probably did a fine job, for all I know.

But there is an obvious missed opportunity for the US firms, methinks. Or is it just too hard?
That's fine for development. It sucks for end users and sysadmins.

From being a vigilant free society to becoming a Stasi(former E.German police that had a dossier on almost all its Citizens) controlled authoritarian society where neighbors spy on each other is not that big a step. We have already lost a lot of freedom via the Patriot Act and the thought of losing more is scary. The price we pay for freedom is that terrorists could one day exploit that freedom to attack us.

There are problems with this strategy too. No matter how hard he tries to isolate his target audience, the owner can't really control how many people show up. Or, the numbers might turn out such that (conventional) advertising is too expensive.

I call BS on this. I have ran into many store owners(though they are rare) who have been having similar success as Groupon for years simply by giving a good damn offer in the paper. I have ran into even more who consistently have crappy coupons and get crappy results. I find very, very few who try a groupon-like offer in the paper and don't see results.

If OSX was native on a vaio z, that would be my laptop of choice.
