Allowing more people to see a post is already possible by adding people to the circles that you shared the post with.
If it hasn't been tested in Safari, they should not state that it does not work in Safari. A better message would be "We have only tested this in Chrome and Friefox on Windows, so this application might not work for you."

It is a bit like the difference between "File X does not exist", and "Could not find a file named X". Computer programs should be polite to the limit of serfdom, or they will come over as arrogant.

Which illustrates the general point: you need teams working the test and checking their answers against what the writer thought the answers were. You also need English specialists checking the wording of the questions.
There seem to be a lot of YC/500 crossovers. I wonder if all of them were 500 first, then YC, or if anyone has done YC and then 500?

AFAIK, there are zero YC/Techstars crossovers.
That's very interesting

It seems the default mutation parameters are a bit low, if you increase it it may lead to better results

I think the main problem with this is that it's using a fixed number of polygons, and apparently is mutating their vertice positions.

If it could be changed for a range of polygons (with a range of vertices, let's say from 3-6) maybe it can converge faster (and better)

But it is nonetheless a very nice experiment. GA/GP is one of those things that really can work with "untractable" questions.
It's been a few years since my 3 stats courses, so pardon if I'm wrong, but aren't his p-values for the logistic regression kind of... important?

Intercept and log(hits) sure, but the rest have rather high p values indicating that it's likely to be present even if it has no effect (lower p-value, more robust, < 0.05 => < 5% chance of incorrectly stating it has an effect (when it does not)).

Or am I missing something basic here?
Yes when teaching GCSE here in the UK where there is an algebra component.

Growing up, I didn’t really know much about entrepreneurship and business, but as I began working in companies around the age of 16 and 17, and started my company, iContact, at 18, I discovered that there’s an entirely different world out there. In fact, there’s a world of prosperity and unlimited wealth out there for you to reach for. You can enter this world. But first, you have to be aware that it exists and you have to work hard to create value for others.

This kind of struck a chord with me. I've grown up in a relatively "unprivileged" (lower-middle class) family, and I think one of the main ideas I'm struggling to grasp as I build my business is that if I work hard to provide something people want, then I'm entitled to wealth in return.

Having lived a life where all I know is that everyone in my family has nearly always had financial difficulties, almost as if we're all undeserving of wealth for some unknown reason, it's hard for me to get into a mindset where I'm able to ask clients/customers for large amounts of money, amounts that might not even put a dent in most people's wallets.

I'm actually just realizing now that if I want to succeed, I'm going to have to break through this mental barrier.

Let's go back to step one:

Google's revenue is rising by what % a year?

Google's user base or searches are increasing by what % a year?

Is there a difference and what makes that difference?

Google's recent stock growth and revenue also match Google's highly publicizes Panda and Penguin updates. Or supposedly fighting "spam" but in reality also ruined a lot of small businesses. My educated guess is that Google is sending a lot less "free clicks" to other sites.

Cost per click can be brought down by a supply gut or a poor ROI for the advertiser.

>> In any case, the considerably more obvious and likely explanation is the one I think most people have tended to assume: google disambiguates terms automatically because it's what works in the 90% case.

In any case, the considerably more obvious and likely explanation is the one I think most people have tended to assume: Google makes sure that any algorithm changes (at least) don't hurt their Adwords business. That's their bread, butter and dessert.
I am reminded of a Native American comedian who had a routine, in which he was describing what he would do if he got caught taking a car. "I didn't steal it, officer. I discovered it." :-)

If you listen to what Douglas says, he does say it's more a "discovery" than an "invention". It was a pattern he'd seen in a few places, and he realized the need for its standardization. In his view, Rebol was a strong influence on that mindset. Hence he credits it in that view, and he feels people should take a look at what the language has to offer.

Prior to the open sourcing in December I was an outspoken critic of Rebol's proprietary nature...but since my demands were met, I now feel comfortable advocating it. (And I do so on a semi-daily basis.) Please do feel free to come chat with us and RebolBot:

I noticed that. I'm thinking it might be because TechStars doesn't have a Bay Area franchise, and YC requires founders to move here.

I have always hated the design of the Porsche. As a kid I was so surprised to learn that this was the famous "Porsche" I had heard so much about. I am not a car guy, and thus perhaps my opinion doesn't matter, but I can at least understand the visual appeal of a Lamborghini or a BMW. Or perhaps put a better way, I can at least see what they're going for. With a Porsche, I'm just kind of reminded of a smart car. Its so tiny and stumpy that it looks ridiculous and straight out of the 80s to me. I actually start considering the fact that it only has two seats (as opposed to most sports cars which I usually forget when just looking at it). It neither looks fast nor classy, I just don't get it. Also, to me it doesn't look timeless, it just looks old. When I see a new one I imagine a scene from an 80s wallstreet movie or something.

> after all, who would be mad enough to put an

The rear-end is where all racing cars have their engine. Sports cars are modeled after racing cars.
The rear weight bias allows for increased rear traction and therefore better acceleration.

Off course a rear-engine is difficult to drive, so there are
sports car with a front-engine, but it's far from optimal from a performance stand point.

The conflict between performance and appeal to the masses: that is in my opinion what Paul's essay is about.
Maybe, but I think it's more than 500 Startups is just a whole lot stronger, particularly in the past 2 years.

Part of that may be that being in SF, at least for part of a company's life, is a huge boost. 500 Startups is really good, maybe better than YC, at recruiting internationally, particularly outside the normal tech network (Latin America, etc.). But they still use the Bay Area advantage.

TechStars NYC might be a viable thing on its own, but it's hard for me to believe that the other cities are really viable for all stages of a company trying to be the next Dropbox or Facebook.

(I do think you can have a substantial non-bay-area presence, but I think you do need some bay area presence, particularly for investors)

Fair point. I do suspect that this is in part due to a difference in user demographics.

People using BioPerl just use it to get something done and don't care to join the larger community. In Perl we call it the DarkPAN.

Meanwhile anyone wishing to use Python will at least have needed to make an effort to learn the language, since there is nothing else quite like it; and as such probably more likely to invest further effort.

But, i do admit that this is conjecture.

"PySlice" with karma 25 is probably your trolling account. If not, ASK about stuff you have no clue about. It is better than looking like a little troll kid, having "fun" lowering the quality of HN by stupid language war comments.

>>where all arguments come in a flattened array

That is optional, through the power of CPAN (and kbenson's methods, of course). Examples of alternatives:

http://search.cpan.org/~flora/MooseX-Declare-0.35/lib/MooseX...

http://search.cpan.org/~ether/MooseX-Method-Signatures-0.44/...

(Depending on if you use Moose or not.)

One of the cool parts of Perl is that the language is extensible, that is why it e.g. has a better OO than Python, Ruby, etc. (Or simple typing of parameter arguments, see the modules above. Or why MooseX::Declare has ... ah, look yourself, troll.)
A few companies like 9gag and Vayable did YC and 500 the accelerator, but others are just YC companies with 500 as an investor. E.g., you see 500/Techstars crossovers in the list.

There are zero YC/Techstars crossovers because both are accelerators only unlike 500. Both YC and Techstars companies view themselves as having gone to the best accelerator program and it's expensive from an equity standpoint to do multiple accelerators, so it makes sense that there is zero overlap there.
I can only speak for myself here, but I find a lot of what you described as "grunt work" to be fun. Yes, it's true that when you work with real world data, you don't only work on the mathematical modeling, and you spend a lot of time just setting yourself up to be able to do what is typically called the "fun" part. For me, personally, I find all of the work involved to be fun-- even setting up a data pipeline and figuring out how to distribute a computation. Automating away grunt work and setup process is fun, too.

Part of what makes data science fun is the machine learning itself. And an equally interesting part of it is is that it involves so many other parts of computer science that a typical corporate job would call "too hard" and isolate you from.

At least based on what I've seen, data scientists are respected and this means they get dibs on the most interesting projects. However, the interesting projects themselves involve a lot of detailed work (that's the nature of technology) and if you're that interested, you're going to want to do it yourself, at least until you really understand the problem (at which point, you'll automate the dull stuff).
"[thumb_down] Spotify doesn't guarantee data security"
I do not really agree on that being a "thumb down" - rather the opposite.

Sure, in Java you don't have to deal with GADTs. But you do have to deal with the fact that people think functions are dark magic and expect you to extend an abstract class instead.

The amount of type wizardry that Haskell permits is far larger than Java and C++ teaches us that in practice you have to expect all possible combinations language features that are allowed. A random Java library will have a far more understandable API than a random Haskell package, since there are not so many permutations of language features possible.

If everybody stuck to just Haskell 98, things would be far simpler.

Besides, have you ever tried to use the equivalent of Parsec or QuickCheck in Java?

As a matter of fact, I just committed QuickCheck-like unit tests five minutes ago [1] :):

https://github.com/danieldk/dictomaton/commit/7aaa89aae68524...

I write such tests in Java quite often. Of course, you don't have the nice combinators of QuickCheck :). I am not saying that Haskell isn't more powerful it is. But it comes at a cost: many packages come with an up-front learning cost, Haskell is hard to optimize compared to Java or C, etc. The Java APIs are predictable, run-time performance is predictable (in the sense that it easy to profile and optimize) and the ecosystem is boring and predictable. These are some of reasons that Java is popular (besides having a steward with deep pockets).

([1] Ps. yes, I know there is a very obvious optimization optimization possible that commit, it's a development branch.)

Perl has no central design? Seriously?

The very purpose it has survived three decades is because it solves a great variety of problems, in a very centralized design philosophy which no other tool has addressed till today.

That moment has come for me and I really need to get into the salesman mindset.
Not easy.
Thank you!
> That's a workaround of sorts, not a solution.

Now that I reread it and some of the responses, I think he's just arguing over the use of the word "solution", not saying he doesn't like the workaround which is what I originally thought. It depends on how you read it.
So true. The Beetle is the C of cars: it may not have the amenities that something that is rolling out of the factory today has, but its simple design means you can understand what's going on under the hood, and keep it running with a very reduced toolset.
>>David Morin appears to want to build a company for the long term, and so selling to Facebook (his old workplace) to kill the project seems unlikely.

What you want and dream, most of the time is different from the reality. Remember that he has investors and employees. Even if investors don't have enough voting shares they can put pressure (at least in the media) and the star employees will bolt to Google and Facebook unless they see $$ signs of a major buyout.

I predict that he will be looking for a face saving exit soon
Is it a good thing that Spotify doesn't guarantee that they won't leak your data? So you're saying that it would be a good thing for them to make it easy for people to steal your payment information?

You can't be sure that they actually delete your data but you /can/ delete your account.
It would work better if you did a local optimization after every crossover and ditched random mutation. I think they call it a memetic algorithm (http://en.wikipedia.org/wiki/Memetic_algorithm).

So take your every triangle vertex (x,y) and differentiate against the fitness (using finite difference), then gradient accent on that parameterization. That will let the triangles fit the edges effectively (I am thinking Mondrian here primarily)
I believe the parent comment is referring specifically to the part about sniffing one stream of information using only the observed it has on another stream (as opposed to the part where the radio is connected to a sound card and digitized).

FWIW, I've been running Debian "testing" on my machine since 2001-ish and I've never done anything special near releases. Except maybe rejoice at all the old packages finally getting upgraded. :-)

For the record, debian also packages up pip and you can install an up-to-date django using that. You essentially get the best of both worlds here.
Google with their search engine and Gmail and GDocs and all the other services they are offering, do provide a valuable service to users.

It's true that users are somewhat the product, the real customers being the advertisers in partnership with Google. However, at least right now, nothing forces you to use their products and leaving Google, even if you aren't a paying customer, is still like voting with your wallet, especially since one user can convince others to leave too.

I personally don't mind giving Google my data. Even though I'm fully aware of the implications, I consider it a fair trade, because really, the data that Google has on me is really not that valuable.

I do have sensitive pieces of data that I need to store online. And because I am aware of Google's practices, that's one reason for why I'm not using GDrive or Picassa. I'm also a user of the browser's incognito mode when searching for porn, a mode that is fair to remind was popularized by Google Chrome.

If I have a beef against Google, is for their awful customer support, even in cases where you are the paying customer. However, that's an unrelated issue and I personally was aware that Google tracked my searches to use for interest-based ads serving ever since they launched Adsense in 2003.

To me the backlash against such practices, are 10 years too late.
That is bizarre, I have no idea why that would've happened.
As stated (e.g. http://lists.debian.org/debian-devel/2008/12/msg01027.html, or the page itself), this seems to be an academical project. It's nice to see people experiment, but I can not see the practical value of this.
As someone who worked for another German webhosting company (not mentioned in the article but more than a million customers), I can tell you that it's extremely hard to roll out new versions of typical software (PHP, Perl, MySQL) when you both want to keep your users on the latest (or a reasonably recent) version while not breaking your users' websites. And because there will always be customers unwilling or unable to switch to later versions, you end up running Perl 5.6, PHP3&4, Frontpage Server Extensions (yes, people still use that stuff) and MySQL 4.

That said, Uberspace is still small enough to take care of their users individually when it comes to support. They can keep their architecture simple (well, so does 1&1, but rumor has it that they have 100 people working in their data center only to replace broken parts in their shared webhosting system), and text-only configuration files and not fully automating everything is still feasible and doesn't hurt yet.

Scaling webhosting while keeping up good customer service is hard. That's why your experience with small hosters will often be better.

Idea: The super simple real-time dashboard.
We all know Geckoboard, Leftronics, Ducksboard, etc. All these dashboards are quite complex. They are designed to contain multiple widgets on one screen. I am thinking about creating simpler dashboard, containing only 1-3 the most important widgets on dashboard screen. It would be much easier and faster to set up such simple dashboard. You wouldn't need to add many widgets to fill all the dashboard screen like in the previous mentioned solutions. You would choose only 1-3 the most important metrics (eg: visits, revenue, sales, etc.). What do you think about this idea? Would you be willing to pay a small annual fee ($10) for such a service?

You still have to know a lot to use those abstractions...like category theory (monads and arrows). You have to at least be able to read the paper even if you aren't capable of writing it.

There is also a kind of compulsion to design elegant abstractions when using Haskell, to think about and understand problems really well before you write a solution. This is not just about the kind of people who are attracted to using Haskell, but the language itself promotes this compulsion. Sure, you can drop into Haskell's imperative subset, but it is frowned on and discouraged.

Java as a language gives you very little, and there is not much pressure to obsess over the design of abstractions. This is both good and bad: good in that you feel less guilt about writing dirty code fairly quickly and with less understanding (to be acquired more gradually via trial and error), and bad in that this code will probably incur more technical debt. Sometimes worse is better [1], ironically (or maybe not) a concept that comes from Gabriel, who is a cornerstone of the common lisp community.

The research shows that if mothers obtain the funds they will spend the vast majority on family welfare ~80% whereas the men spend less than 40%.
The difference seems to be attributable to the man having a greater sense of individualism in how they apply the funds and also they incorrectly overestimate their ability spend the funds in profit seeking ways eg gamble the funds or use the funds towards seeking new funds.
My point being that to guarantee that would obviously be irresponsible - since there is no such thing as 100% data security. It's way better, in my opinion: "you probably shouldn't put anything too sensitive here - we have been hacked and will get hacked again". Obviously they will try their best to secure their systems either way, this because the biggest cost is the "user reaction" (users leaving the service or alike) when getting hacked.
