Thank you. But I was more interested in YC's perspective. I've done enough research and am confident i can write a good application (I've written business plans and pitch decks and raised money with them too before)

However I was curious about why YC selected those single founder startups. Of course the application has to be top quality, but I'm sure there are lots of others whose applications are top quality but still don't make it.

Thanks!

Yale and Princeton student cultures could not be more different. Yale attracts a more ultra-liberal, save-the-world student body, whereas Princeton attracts a more ultra-conservative, make-the-money student body.

It doesn't suprise me that the original posted article came out of the Yale's student newspaper, instead of a Princeton one.

Amazing that this post hits HN the same day Oracle announces "Oracle NoSQL Database" ... http://www.oracle.com/technetwork/database/nosqldb/overview/...
<<Has any popular git hosting site added mercurial support?>>

Yes. In fact Github implemented the Git plugin for Mercurial that lets you use Github (or any Git repository) with Mercurial as your client rather than Git.

I guess this shows which DVCS is winning?

Nice to see some similarities to what we have done at http://utopic.me/

The news board seemed 80% from one source, BBC. Would love to see more variety. Did not really understand your rating algorithms there. Clicking on the news opened just 1 sentence of the news item. Either redirect to the full webpage or use full text scraping like Flipboard/Zite do (keeping of course copyright in mind).

Some objects you have don´t have photos and then the headline jumps to the top of the object, which is distracting.

After registering, I now have just an empty page under my first board, saying no threads found. Not sure what I should do next.

Good luck - better (big data) content discovery & personalization projects are always needed. And try to find a specific niche - it´s a very tough and coverrowded market.

I didn't see the presentation but it looked to me like the hate was really focused on the dev team structure that had DBAs owning all the sprocs. I've seen this on other teams I've worked with and it is indeed a nightmare.

For whatever it's worth, you shouldn't need sprocs for security; in fact, sprocs provide one more way for SQLI to sneak into your code (dynamic queries based on tainted input inside the procedure) --- something that comes up a lot when DBAs are forced to be a first line of defense against attacks.

There's nothing wrong with stored procedures per se, but the architecture where every database call is a stored procedure matched to a use case from a higher tier is error-prone. PL/pgSQL is not a great programming language.
I will readily admit that I am biased, A good deal of my experience has been in large high load web systems with a good deal of legacy environments. When it comes to the final end point for my data I like relational structures. Personally, I find them more adaptable to the unforeseen as far as business insight is concerned, and in the environment, that I have worked in, the unforeseen occurs daily.

For example, a marketing manager wants to aggregate data set X against Y to see the outcome. The more data I have in structures that support these unforeseen and ad-hoc requirements the more insight my organization obtain. So personally for your situation I would front cache the data in an NoSQL type structure and bulk transfer it into a relational structure at set intervals to avoid having to write logic in an application layer for each use case that comes through the door. I know that there are emerging tools in this space for the NoSQL databases, but I still find analytical and reporting easier to do in the relational world, relational models seems to lend themselves better to discovering links between data sets after the fact.

Imagine that, within a year, a modest 25% of Facebook users use their browser. That would equate to about 200M users

The reasoning is backwards. Converting 200 million users to a new browser is not a trivial task. In what way would a facebook browser allow people to better access facebook?
"Imagine that, within a year, a modest 25% of Facebook users use their browser. That would equate to about 200M users; all of which are using their search."

I'd be willing to bet that a significant percentage of Facebook's users don't know what a browser is. They fire up Internet Explorer and are blissfully unaware that there are alternatives. This has been my experience with non-techies.

Those who do know what a browser is are likely to have Chrome, Firefox or Opera installed and probably see no personal benefit in downloading yet another browser. They are also unlikely to want to have Facebook invading their privacy even more.
Whether or not you have to pay for your commute probably depends on who you work for and what your contract is. I worked full time for a Japanese company, and they did pay for my commute; granted, I was also being paid a typical Japanese salary, not an expat salary.

What's It Like To Be A Street Performer?
I saw him mentioned in a Discovery Channel documentary when I was in High School, which surprised the hell out of me.

I don't know how interesting it all is. He basically showed up in the Combat Zone one day and went from place to place telling them they were going to start paying him. The guy they were already paying got disappeared, so they complied.

Over time the territory came to include Chinatown (which abuts the Combat Zone), and he eventually got hooked up with the non-Irish mob in Providence (where I guess he was one of their better earners). He also apparently stole a lot of boats (very easy to steal, very hard to track), which when I found out helped explain to me why my grandmother was Admiral of the Quincy Yacht Club without ever owning a boat.

The FBI issued an arrest warrant for him the day I was born, so he fled (apparently to California). They seized all my mom's assets (in an effort to get her to cooperate), and tailed her and I everywhere for most of my childhood.

He ended up getting arrested back in Boston in the early 90's (A few years ago I worked at the same company as the prosecutor who tried his case, which we both discovered one night drinking at a company off-site...awkward conversation).

From what I know, he's now living in Southern California (he had a security consulting company...which I suppose it somewhat serendipitous considering that both my brother and I ended up working in information security).

I'm not one of those people who believes that people are "good" or "evil", but if forced to decide one way or the other, my dad falls pretty squarely into the "bad" camp. The thought of him participating in an IAMA on Reddit is about the funniest thing I can think of.

The hg-git abstraction is not very solid. You end up having to "think git" rather than "think hg" and my beef with git isn't in the syntax, it's in git.

If I'm going to use hg-git, I might as well use git itself. I don't want to use git; I want to use hg.
I like hanging out in Japan and I can confirm this.

Last year I spent 2 months right outside Tokyo (on the Keio-Inokashira line) and this year I'm here for 4 mo right smack dab in the middle of it.

Since I'm only here on a tourist entry visa, I can't get "real" services so I'm paying 140,000 yen/mo in rent (for an admittedly pretty decent place, and no "key money" and they charge it right to my credit card) and $250/mo for an unlimited data SIM card rental (can't even get prepaid without a proper visa…), but aside from those inflated costs, everything here is the same or cheaper than in Sweden. Especially eating out. E.g. back home you can't get any prepared meal aside from sloppy tax-evasion kebab for less than 90 SEK (US$13) but here you can get away with it for at least half of that.

Public transport is about the same price as at home, but it's really easy to underestimate how big Tokyo or even the whole country is. Thinking "oh I'll go to yokohama for that party" it's really easy to forget that at home that'd be the equivalent of taking the train to the next country over.

I absolutely love it though, anyone even remotely considering coming here should definitely do it, even if just for a short while. It's an amazing place.

Edit: oh yeah, I got an ear infection while here and had to go to an ear doctor without any insurance. For the first visit (which included a signup fee, a hearing test and a prescription), I paid $150, and the 2 followups each cost closer to $40 each. This sounds about right for what I'd pay at home if I wasn't european and got free healthcare (my reference for the cost of European care comes from my parents, they moved to Australia and lost european coverage so when my mom fractured her jaw when she was here for a visit she had to pay out of pocket).

If you want a canonical example of an algorithm that's imperative and harder to do in a functional setting, cite union-find (See "A Persistent Union-Find Data Structure"). Searching is optimal in a functional setting, too. Just not the classic quicksort.

Credit card penetration is really low so your other options are bank transfers and CVS (paying at a convenience store). COD is actually quite popular but I can't imagine any SaaS could implement that effectively.

I don't have any experience with direct bank transfer systems in Japan. I believe that a lot of Japanese Banks now offer NetBanking as a payment option for CVS payments but I'm not sure how widespread the use is. I'm also not sure what is culturally common in Japan for billing recurring online services.

Perhaps someone on HN who lives in Japan could comment.

Not sure who you're using as a gateway but I do have memories of being on the line with technical support and a Japanese translator.

Ah, I see; it was just the first commercially available relational database - at least according to wiki, it beat the commercial version of System R (System/38) "by a few weeks" http://en.wikipedia.org/wiki/SQL#History I read somewhere that it was previously thought of as nice theoretically but not fast enough to be practical.

I'm actually very interested in what made the relational model so commercially successful, if you happen to know more about it (it's hard to judge now, because so many other features have been added and market standardization etc). The mathematicians say it was because it's based on a mathematical model - but that doesn't sound like it would be very convincing to pragmatic benefit-oriented business buyers.

EDIT that pdf looks pretty good - I'll have a proper read of it when I get the chance - thanks

Developers are religious. Whether it is vi vs emacs, or IDEA vs Eclipse or Mac vs Linux. In September we had a huge debate internally (hundreds of comments long) on functional vs non-functional programming.

We know that no-one wins in these religious debates.

We've found that developers are equally religious regarding their DVCS. Most frequently it is whatever DVCS you started with is the one that you're passionate about.

We've found that most companies of any size have both Git and Mercurial lurking somewhere in their development ranks. Previously if they wanted to host their code in the cloud (and who wouldn't), they would have had to choose two different hosting providers. As a developer, this was a pain as you never knew where your code was.

Now that Bitbucket supports both, you no longer have to choose. We think this is a huge win! Companies can store all their code in one place. And with the per-user pricing, it is a very fair pricing model (don't have to think about whether a fork is going to cost you or not!).

Most of the content from the site is from RSS feeds. This is why there are lot of descriptions that are short. Hopefully users will add stuff and I can wean the site off this automatically submitted content.

But, you are absolutely right. I am not showing the user that they need to do this. This is probably the hardest thing to do, for me, right now.

I think the confusion here is based on the difference between "multi-master" replication and "master-master" replication. MySQL doesn't support the former, where a machine can be a slave of more than one master, but it does support (like you eluded to) having two masters (usually one writable, one read-only) in a loop, which MySQL folks call "master-master" replication.
Yeah, I'm a happy developer that uses both bitbucket and github - I'd just wish that ui for bb gets nicer and more friendly - and it will be perfect tool for me.
The adoption rate for Facebook Browser or even toolbar will be very insignificant. Why?

Majority of Facebook users (35 - 45 yr old females and older) are not the crowd who like to install or capable of installing a new browser or even a new Firefox or Chrome toolbar without the help of GeekSquad or their nerdy nephew.

The other majority are tech users who are already on Firefox or Chrome and the last thing they want is another browser or let Facebook monitor all the websites they are visiting (although this is already happening in some levels)

Agile - 'A' For Adjective
Just because something is successful doesn't mean it's right. I get what you're saying, but it doesn't mean that successful systems are exempt from intelligent discussion about where things went wrong. A lot of poor decisions are propagated because people are building on "successful" technology.

How can I get Qt4 running with ruby 1.9.2 on Windows 7?
Any semi-serious developer is going to use up the 5 private repos really quickly. 20 repos ($22/mo) is easily achievable for anyone who likes side-projects, and after that, larger plans are only "available on request".

I wouldn't expect GitHub to compete directly with BitBucket's pricing, but doubling the amount of private repos allowed wouldn't hurt.
Does Groupon have any sort of lock in agreement with its merchants? I've always wondered how these businesses are defensible; apart from negotiated deals, the services are more or less interchangeable.

This brought up some repressed memories. As part of the same argument, people were advocating for keeping executable code (VbScript) as well as HTML strings in the database layer.

I think part of the issue with learning haskell is that it seems to invert the typical learning strategy for programming languages. Usually the best advice is read a little, then write a lot. Typically you can just look and some published code and go "ah yes that's how you do it". But I find, for better or worse, Haskell really requires you to understand before you code. Which in the end means your study to code ratio is very different than almost any other language.

Most languages, even lisps, are somewhat tolerant of 'programming by guessing' for beginners. Usually you write terrible code that works, learn more and see what you did wrong. Haskell is very unforgiving of this, if you don't understand why it works it probably won't
As noted upthread, hg-git is a very poor facade.

The problem I have with git isn't in its syntax. It's in more central decisions with which I disagree fairly strenuously (I am very strongly in favor of indelible history, for example).

What a cool and elegant way of publishing a tiny gem!

However, I will say that I personally prefer to stay away from gems like this, as they add indirection, and make projects confusing for new devs.

I would say that

bang :calculate_score => :score

is clearly worse than

def calculate_score!; update_attributes!(:score => calculate_score) end

Sure, it is longer, but any ruby / rails dev will understand it instantly, and I'll take a few more chars for less indirection.

> Polymorphism that can only be implemented using existential types plus Typable?

I'm curious where you came across this. In an external library you were using, or in the process of trying to implement some kind of dynamic typing in your own code?
Process is rules that stop people from being able to do things they shouldn't

People tend to disagree on what should or shouldn't be able to do. Should a developer be able to release code to production servers? Should a developer be able to change the database schema? Should a developer be able to access the database tables through an ORM or ad-hoc SQL or must everything go through stored procedures?

A healthier way to look at process is that it's about facilitation, not control.
