I believe it was made clear that their last raise will be the final round they will take so whatever they do will need to make the business sustainable in the long run. My guess is by participating in YC, they can:

- Find up-and-coming businesses that are tangentially related to Quora's mission that they can groom and perhaps invest in.

- Incubate within the YC ecosystem some spin-off businesses that may not fit well under the Quora brand and what they're doing.

The existence of an operator< or the existence of a template specialization. Not as nice, and incapable of runtime polymorphism, but that's typically how it's done. Concepts would have been more explicit about it but they're also compile-time only.

Interfaces or pure virtual classes are not the same because they're closed.
Oracle v Google could drive a new era of open-source APIs
I got an email from a Quora product manager a little while ago asking how I used Quora and what I liked about it. Seems like changes are coming.
I'd be willing to make the bet that the valuation of Quora today ($900mm?) is lower than the peak valuation of at least one YC company founded S12 to S15 by 2020, adjusted for inflation.
Yes I think that was mentioned in the copy. It's also not really "random." It's one of the last 20 tweets globally. You probably won't ever see a tweet older than a few minutes.
Right, but the problem for Google is that Judge Alsop ruled as a matter of Law that API is not copyrightable. So that mooted the defense for Google's actions under fair use. This seems like a major ruling. Now Google is going to have to go back to trial with a fair use defense as the outcome of that portion of the original trial did not provide enough factual basis for the appellate court to rule.
I'd be down to help you in making that.

I wonder if YC is not taking any stake (or a very small stake) in Quora. They do not really need it, perhaps it's just beneficial for both parties.

Quora gains a large number of connections, possible companies to fund/buyout, a network of founders to answer questions, complimentary services, and some prestige.

YC gains a larger network, another large(ish) player in the tech industry, and potentially some money from an investment.

OR

Perhaps YC put something like $8mm into Quora for a slice of the pie, but I'm guessing the first one.
If they had an email box to get the tracks emailed to me, I would have signed up right then and there. As it is, I probably will forget about this.
Or, google? It seems the content-farming biz was killed primarily by Google's algo changes over the years.

> Isn't this just the same as Dynamic Programming?

The two concepts are very related. I would say that corecursion is more low-level and more general. It's also true that DP is not really a computing term. DP is an optimization technique which, when performed using a computer, is often coded using corecursion.

See the comment by chriswarbo[1] for both an excellent explanation and some examples that I don't think we would call DP.

Exposure to neonicotinoids impairs honeybee winterization before colony collapse
Hey cpeterso the first cab was somewhere between 3500 and 4K to build but we did all the labor. If you calculate that into the equation, it's more like 20K. Our current cabinets are more expensive, they retail at 12K, so it's not the kind of thing you will buy for your room. They are built in Wisconsin, are of higher quality and also feature better TVs. We'll ship wherever. They include a coin door and are really made for public spaces like arcades, bars, student unions etc. We're figuring out how much money can be made on them and it's looking very good that you can recoup the money in less than a year if it's in a well trafficked area. Our goal is to get them closer to 10K or less. Believe it or not the computer is only about 400 of those dollars, the bulk of the money is the cabinet, joysticks and TVs. We are looking at ways to make them cheaper but we'd have to build quite a few of them to get economies of scale working for us.

As far as game play tweaks, it's not really any one big thing, it's more about little tiny changes that we keep doing in response to tournament performance. We did change the way the soldiers look and made variants on the workers so they are easier to distinguish from each other. The big changes have been in making it Arcade ready, adding an attract screen, music, code for taking money, UI elements to let people know that the game is about competing with the other cabinet, instructions etc.
Or better yet, is there a webapp that lets us ask questions and post answers for others?

Never mind a bot farm, this is incredibly useful to anyone who has just one 3d printer.

Normally I have to sit with my laptop plugged into my printer by USB for the full duration of a print, which can be hours long. This lets you print from wherever you want in the house, and cuts out the crappy slicing and print hosting software you currently have to use.

If you can really print in 3 clicks like they say they can, I'll be sold.
I rarely initialize my use of Quora by visiting the website - I have found immense value in the digest emails they send. They are a mix of things they know I'm explicitly interested in, and generally "interesting" things (presumably defined by popularity). Probably 90% of the time after receive a digest email, I open at least 2 or 3 of the links within.

I have tried visiting the site directly and am rarely able to find content as stimulating as the links they send in the digest emails.

I made an app which uses the idea of spaced repetition to help you memorize flags. I was really amazed when I learned about this system a while back, and made this app to help my niece learn some interesting stuff. My app is really rudimentary and buggy, but I believe we are soon going to be seeing plenty of apps which incorporate these kind of ideas and really help us hack our learning process.

That sounds pretty reasonable, actually. Sure, you can make the case that if 40% of the apps are down, then that's a whole-service downtime, and should be counted as such. But what if it's 4%? Or 1%, or 20 apps? Should a downtime that took down 20 apps be counted at the same level as one that took down 80% of all of their apps?

Seems like the best compromise is exactly what they did. The numbers are about as relevant to people looking to serve their applications as they could be without breaking things down by availability zone or stack or some other metric.

I'd make damned sure that a format in the preferred form of the work for making modifications to it be specified.

PDFs can be modified, but you really don't want to do that. Far better to get source in LaTeX, DocBook, RTF, Markdown, or some similar format.

Better: insist that the tool not only be capable of outputting the chosen format, but that it do so by default, as a matter of course, and without any error, warning, or other dissuasive dialog (e.g., "some formatting changes may be lost") in the process.

While it's not the only company to do so, Microsoft's gaming of file formats for lock-in advantage is legendary (and yet another reason I avoid the company's products where at all possible).
A matter of requirements and principles. I'm currently discussing that change in my family, because I don't need

Motivation for Simple Factory and Factory Method Pattern
That's rarely a productive question to ask.

It's just a slight variation on the totally unhelpful "Why don't you fix the bug yourself?" response that's sometimes given to people reporting a problem with an open source project.

They're useless questions because the answer is pretty much irrelevant.

Maybe he doesn't know how. Maybe he isn't qualified. Maybe he doesn't have the time. Maybe he doesn't have the money to fund somebody else doing it. Maybe he just doesn't want to.

It doesn't matter why he might not do it himself. But that in no way means he shouldn't publicly express such interest in such functionality, in case there is somebody else who is willing or interested in adding it.
And the rest of us will forget 10 minutes from now.

I really don't understand why people give quora a free pass on this when expertsexchange was nuked by the rest of the online community for inventing these tactics.
What a humbly ambitious move by Quora.

They sure aren't happy enough with where they are or heading to; still they know they need help to change ways.
Well, doesn't it seem like the circuit court has answered this question in the affirmative?
> They didn't highlight the key property of a project for when tdd works and when it doesn't: when you know the requirements with clarity (compilers, stacks, etc) it is possible to use tdd since the tests will map back to well understood requirements. But when you don't (like building a website with fussy browsers, or writing a log file parser with format anomalies), you don't have the foresight needed to write the test before the code.

Actually, I think TDD is particularly useful in the last case (writing a log file parser with format anomalies) since you end up with a lot of edge cases where, before you can code to handle each of them, you have to determine exactly what the code should do for each case, often without a clear logical superstructure that explains it all. So you of necessity are incrementally developing a set of test cases before you code to handle each of them -- so if you codify them as automated test cases before you code each, you not only get testing that you handled the new case right, you also get regression that you didn't break the previous ones with the change.

True. But the hashes Nix uses in folder names make it a bit more complicated than it has to be. But I like both GoboLinux and NixOS and really hope one of them or a similar approach takes off some day.
I think this is just Quora wanting the YC branding to make them more hip. I'm thinking an underhand deal went through to get them in. Quora has the wealth and influence to make that happen. The OP is just preemptive damage control.

Bring on the downvotes.
It's most certainly in dispute. I'm disputing it right now.

Is it clear that The Open Group or IEEE actually have a clear right to claim copyright of the POSIX api given this ruling? Were they assigned or licensed that copyright by AT&T or any of its successors? It seems likely enough that in the 80s this was not seen as necessary, and the old guard of UNIX implementers were still being quite belligerent towards each other at the time, afaik.
The Smalltalk developer experience may in some ways be one of the better parts of Smalltalk, but at the same time it's also one of the worst.

Getting tied into a particular environment often made it awkward, if not practically impossible, to integrate with other editors, code manipulation tools, version control systems, and so forth.

This might have been okay in academia, but it was far less acceptable in industry.

Ask HN: How do you save comments?
Would people be interested in the ability to 'save' comments? Ie, rather than just upvote them.

Unlike stories which get saved to a list by defaul when you upvote, it's not readily accessible to find comments that you upvoted.<p> Not every upvote would warrant a save, but a list of select comments as a unique feature migh be interesting. Items for future reference / excellent candidates for this feature might be eg: (a) Technical refrence posts; (b) test-piece writing samples; and (c) myriad how-to's (say, interviewing advice).

<p>Alternatively, what are people's best solutions for saving comments on HN? Simple bookmarks or are there better solutions?<p>The ability to peruse a "saved comments" section on HN seems like it would be easier to read/sort (because it has both title/context link as well as the text).<p>

Feel free to comment if this is also more trouble than its worth.
Sounds like a partnership not an investment.

> I haven't used backbone at all, and only know what I've read about it

I find it mind-blowing: do you only use tools made inside Facebook? Do you develop these frameworks or just use them? If you don't know Backbone which frameworks did you learn of this kind? I'm curious.
I don't think the deliberate making of Android incompatible with Java had much bearing in this case. Oracle might not have liked it, but it wasn't part of their claims, I don't think. It was discussed as part of the context for Google's choices.
Speed definitely still matters for everyday apps on mobile devices, because their processors are so much slower than actively-cooled desktops and laptops, and because touchscreens demand a more responsive UI. JIT runtimes have gotten faster, but statically compiling to machine code (especially when link-time optimization is used) cannot be beat for things like application launch performance. And the machine code that Objective-C compiles down to is definitely more native than bytecode for a JIT VM.
Very cool! I welcome Quora!
Just to add to the list: Scala takes a lot of nods from ML and F# is a nice variant if you're on .NET.

> Why is that a problem?

Totally not a problem, except you very quickly fall down the slippery slope of mystical nonsense :D

If we cannot define the boundary of consciousness (the smallest conscious system) eg, we take a conscious human and take one neuron away at a time, at what point is he not conscious? I’m not talking about not being able to communicate with us to tell us he is not conscious. I’m asking at what point are then just a lump of triggering neurons and nothing more than a machine. Is it a hard boundary or sliding scale of levels of consciousness that goes all the way down to a small system of neurons, single neuron, atom or even further?

If we can assume consciousness can take forms (given the appropriate computational configuration), such as existing at different scales such as a system of birds or a star sized metal machine made of cogs computing the same system as brain does but “experiencing consciousness” at 1 human second taking billions of years (Or a super computer experiencing a lifetime in a microsecond). Or still be conscious while not being “human conscious”, eg animals, accidentally (brain damage) or planned (augmentation) reconfigured brain, or just some totally different novel system such as a galaxy.

Just those two examples of thinking about consciousness very quickly get you down the rabbit hole of stuff that sounds like mystical nonsense. Eg Could the universe be conscious in some form at some size and time scale?

btw.. I'm not saying those assumptions are correct but I would hope they are reasonable to think about.

EDIT: (the smallest unconscious system) -> (the smallest conscious system)

That article is .. devoid of new information. It claims that we don't eat swans (maybe? probably? I certainly never did.) but fails to provide even a hint of an answer. Unless I miss a hidden link for a page 2 or 3 that is a very long "So we don't eat a big bird, think about it", which is .. thought provoking if you're feeling nice, lacking content if you're not.

Jumping between vastly different regions doesn't help either ("Swans are the property of the crown in the UK, but a pest in Michigan." What??).
Is see in this comment and its answers, "most optimal", "more optimal".

An algorithm is optimal, not more, not most, just optimal.

For the case going here, you will have difficulty to prove any optimality, since the process involves humans. Efficient would be a better term than optimality.
You really have to visit the site, the emails only contain snippets of conversation.

EE moved stuff to the very bottom to get around it. but I agree, quora should get nuked from SERPs for this behavior. Despite having an account, it's a pain in the ass to login to see something with results blurred out.

Concepts will certainly be nice once they arrive in the standard, but it is already possible today with some trickery. Example checking whether an std::vector<T>'s type is comparable with `operator<`: http://coliru.stacked-crooked.com/a/2ea46e0afd894d3d

The error you get if you try to sort a vector with an unordered type is relatively easy to read:

main.cpp: In instantiation of 'void merge_sort(std::vector<_RealType>&) [with T = type]':
main.cpp:45:17: required from here
main.cpp:30:5: error: static assertion failed: Element type is not sortable
