Did you 'come out ahead' in the sense that you made money, or in the sense that you beat the S&P or similar indices?

I don't doubt that you, specifically, may have beat the S&P, but I think lots of people don't keep a great track record of how they've done, tend to forget their average or bad trades, and overemphasize their good trades in their minds. I'll then ask them how much their overall portfolio has grown from year 1 to year 5, and then calculate the S&P's growth in that time, and they almost always have only managed to match it (with a lot of time wasted to do so) or actually did worse.

I found some slides [1] explaining how this works.

A less poetic example of privileged information: if you're training on time-series information, you can include events from the future in the training examples, even though they won't be available while making predictions in production.

Apparently this helps the machine learning algorithm find the outlying data points when the data isn't linearly separable.

The 2 volumes of authoritative X documentation came from Digital Press. X Window System by Scheifler, Gettys and Newman. X Window System Toolkit by Asente and Swick. If you read further in the acknowledgements that you quote, you'll see them listed as primary sources. My copies take up 3.25" on the shelf.

I know we had a lot of the O'Reilly X books floating around. Nobody ever read them, but we felt weird throwing books away. You're right that they got bundled by vendors--I think HP and Sun eventually bundled stuff too. The bundling decision was probably more about trying to justify insanely high workstation prices than an indictment of the complexity of X.
They set out to create a question/answer site with a better user experience and a better community.

Their user interface choices always looked seriously weird to anyone familiar with almost any other website. It's beyond annoying to me to see a Quora link shared by friends (and actually quite rare for me to see a Quora link shared by anyone), because I never know if I will be able to read the Quora thread without logging in or not. Today, in this Hacker News thread, both the OP and the links submitted so far have been instantly visible to me, but that is not my usual experience with Quora. Rather, my usual experience, through several changes of Quora policy, has been to see nag screens asking me to sign up before I see any of Quora's content.
how is that sexism - look at the stats behind who edits wikipedia, who posts here or at quora.

prove me wrong, with science.

it is the opposite of sexism - it is an uncomfortable truth.
iPhone 6 Store Checker using Node.js + React.js
It's more than a little bit humorous to see a Quora post wondering if Android is doomed.
I thought Quora's philosophy was "blur the page and cover it with a modal signup form".
this is an intriguing criticism but assumes a corrupted reputation economy. wouldn't a perfect meritocracy be a reputation based economy?
It feels like the post is from 2008.

>where competent developers no longer need to understand binary

Experts master their dependancies. All software depends on binary representation. All expert programmers need to understand binary.

Of course, you said "competent" and yes, you can get things done without knowing binary. Although it pains me to think that it can't be understood or explained simply! Bitwise or is so foundational to many techniques, like efficient storing flags, security, and so much more.

BTW a 'bitwise or operator' loops through the digits of a binary representation of both operands, or's the binary digits, and outputs the result. That one little operator has elements of a transform, a for-each (or a map(), if you like), and a logical operator, all in one! It's powerful and cheap to compute, and programmers and others, would do well to learn what it does. One practical, everyday use: numeric arguments to chmod (e.g. chmod 712 myfile.txt)! The reason why the modes are assigned to powers of two then added is so that they can be recovered from a bitfield using...bitwise or.

I'm not dismissing the value of mentoring that easily. Just because I don't go to the Ivy League school doesn't mean it's irrelevant which university I pick. I've spend most of the past 2 months going around and talking to as many smart people I could and it had a tremendous value for me. I greatly improved my business plans, my pitching skills and pretty much everything about my project (everything but the product itself).

It isn't `mansplaining` just because a man is writing something. I also wasn't aware that writing source-backed articles for an encyclopedia is actually a secret plan by men to oppress women. If you're of the opinion that any time men write or speak on a subject that they're `mansplaining`, perhaps you should reevaluate your world view.

[Sam Altman in his last startup class went as far as to say that non-tech people have no business founding a tech business, quoting "software people should found software companies, media eople should found media company". I found that a little bit sad to hear.]

If that were the case, we wouldn't have the largest IPO in history because Jack Ma would have been unqualified to start Alibaba.
I think it fits their development process very well.
For the NLTK idea, I think you can get a long way by adapting one of the examples from the (free) book: http://www.nltk.org/book_1ed/

Raft is conceptually deep, but code wise isn't actually that hard to do. However, it gives you a beautiful introduction to consensus algorithms which appear in many distributed systems.
I would recommend this as well. but i see no reason why this person cannot be your cofounder. If you are building a software based company it would help to have a technical cofounder with a vested interest.

You don't sound like a traditional start-up, so most of the advice form startup school may not apply to you. You probably don't need someone who actually writes code day to day. I would get someone with high level expertise in building and running technical teams who can start from one developer and scale up. That person will lay out your technical infrastructure while you focus on the business side of things. This is definitely not an easy find, and is harder than finding some smart student who wants to play with latest technology x that does not fit well with your business plan.

This attitude is common amongst my peers. I don't understand it all.

In general any time you do something for CS it's either trivial or if you had some qualification to back you up you could get paid; you're not paying for the privilege of designing their website you're paying for the support, guidance and ultimately assessment of your skills.

There is a problem of larger scope which is that education at a school level has been poor or non-existent as side effect of this is many people self-teach and then start university with skills way beyond their peers, web design is a good example of this because it's a relatively open platform that's easy and fun to get into, the result is that most universities must start from no assumed knowledge in the field.

It's only because you were able to teach yourself webdesign that you feel that the task is beneath you. If you really want to address this problem you need education to be better across the field so that university level can address significant tasks rather than filling in the basics for the first 2-3 years. This is starting to be addressed in the UK by the likes of the Raspberry Pi foundation and at a government level by mandated CS education in primary school but without incentives for teachers to take up the subject I don't know how effective it will be.
Wow, looks promising. As this also could be scary, perhaps you can describe on your site what happens when one clicks the button.
Some of the comments here are really interesting. A lot of general Quora negativity?

I think the weekly (semi personalised?) Quora 'digest' is one of the only bacn emails I'll open pretty much without fail, almost always ending up on the site. Some of the questions/answers are fascinating.
the majority of comments on this thread are off with there suspicions of foul play on the "hackers" part.

the details from the article mostly add up. there is information missing that could confirm this (review of skill-set showing competency in side channel attacks, perhaps a followup on the DAPRA grant) but the general attack described could be possible. also intelligence agencies looking for snitches should be read as an agent fishing for a spy. A special type of spy with technical skills. It might be that after hitting the first "go higher him and bring him into our RED_or_Black team" later the agency got cold feet or countered and as a result they could only offer him the more arms-length freelance type of position where you work on blackbox projects while remaining independent but also have the alternate task to feed information about the community. This. Happens. This is the modus.

The only thing I do not get is when they were still looking to higher and put him close rather than the arms-length position, why the "would have to move to Seattle" requirement? And this sparks my attention because pre-snowden I knew several security analysts in Redmond that doubled as consultants for Gov. I wonder if Gov eventually just setup shop there?
For a few seconds I thought this was an actual site.
In Major League Baseball (http://mlb.com), the season lasts 162 games, from late March/early April to the very end of September. Game 163 is played, only if necessary, as a tiebreaker game (https://en.wikipedia.org/wiki/List_of_Major_League_Baseball_...) that usually determines which team is heading to the postseason and which team is “going home.”

Why 162? In 1961, the American League expanded from 8 teams to 10 teams, so instead of playing 154 games against 7 different opponents (22 each), a team now played each other 18 times. (This also works well because 18 is a factor of 3, and baseball often plays its games in a series of 3, held at the same ballpark.) The next year the National League followed suit.

If there are any Game 163’s this season they’ll happen Monday.
Most "funny" comments are just not funny. Comments that don't add anything to the conversation should[1] be downvoted. Funny comments that are funny tend to get upvotes. Humour is harder than spouting movie quotes or similar meme-based stuff.

[1] downvoting on HN is currently perplexing. Easiest way to get downvotes is to make a post with a clear but simple factual error - something easily fixed with a comment and an edit. In another thread someone was told to "go and die" and that comment is still live after an hour or so.

This article kept getting better and better. I thought this was particularly interesting because it leads to a world where the AI software is available to all, but what's of value is the rules or metaphors you've developed for your robots. That would give garage hobbyists a chance of coming up with their own special formulas and possibly be the ones to figure out something novel or world-altering in AI.
The New York Times has also been publishing a number of these interactive types of articles.

* It's broken on other platforms, because those platforms are unable to provide sufficient primitives. LibreSSL directly inspired the introduction of a long-needed getrandom(2) syscall in Linux, and the LibreSSL-portable release still works on a decent number of platforms that will definitely be growing. Did you forget this is an early project? If anything, LibreSSL will ensure that other platforms get off their asses and actually do something about security, as OpenBSD has been trying to yell about for so long.

* In case you missed the memo, LibreSSL wasn't stable back then (nor is it still, AFAIK). Of course things will break, it was still development releases and pre-alpha testing. You can't fix a mess without inevitably breaking someone's workflow.

* They're making an API that will improve on the cruft of the old one, and actually be reasonably sane. Being agnostic of implementation internals will mean easier language bindings. They also explicitly stated it's meant to be independent of LibreSSL and can be adapted to other stacks.

* Stop bikeshedding about version control. It gets old. OpenBSD has had probably the most proactive security auditing and code review practices out of any other project in nearly two decades: http://www.openbsd.org/security.html. Code review isn't some magic process, it's a practice that can be done using a variety of methods. No doubt independent audits will emerge as soon as LibreSSL nears sufficient finalization.

The LibreSSL website is only a brochure. It's made to be "unprofessional" on purpose. The developers have a technical, no-bullshit and take-no-prisoners attitude.

And of course, next time we hear of OpenBSD having more difficulties, people will jump about Theo de Raadt being mean. I'm starting to understand where he comes from.
My advice. 1. Try to get your MVP out asap with a young tech graduate/internship/ from Bristol University CS department. It will give you time & opportunity to find what you are looking for. Forget meeting technical co-founders like you would date people online. You have more chance of winning in the casino that meeting your tech partner online. Best you start solo than chasing first your tech co-founder.

2. Use your network as I am sure you must be linked to some great folks/friends.

You have to think as your co-founder (tech or not) as your most important relationship before hire, customers and also definitely investors. All the best.

The answer is very much "it depends". I work in the electronic trading industry and have for ~6.5 years.

If your math skills are very good and you want to work as hard as you would as a CEO in an early stage startup, your pretty much guaranteed to make a LOT more money in finance. Ditto if your solely a quant and not a trader or a quant/trader.

That being said, if your startup makes a glorified text messaging program that Facebook buys for a cool billion $$$, you'll be sitting pretty. Statistically, you're much more likely to succeed and make a lot of money in finance. Each company is different, but many firms let traders keep 3-6% of their PnL as end of year bonuses. Extremely good compensation is the name of the game in finance, but in a startup it is like playing roulette. Your wins can be a lot bigger, but so can your losses.

If it was me, I'd go finance, but I'm a technologist at heart and absolutely love the tech I'm able to work on with the tech budget of a solid financial firm.
Quota. ?share=whatever

They should have looked to StackOverflow as a good example of how you build a proper community, and more importantly, nurture it.

Good ridance.
I agree with some of the points the author makes (although I've never contributed to quora myself) but I think he's misguided there.

In my opinion the problem with humour is not that it can be misunderstood by international readers, it's that it's very hard to find the sweet spot where the comment threads turn into a competition to find the wittiest/stupidest joke/pun on the article being discussed.

I think the issue is that most jokes don't really contribute to the discussion and unlike slashdot you can't motivate your vote (+5 funny vs. +5 insightful). There's also the problem that humour is hard to judge objectively and is likely to annoy as many users as it amuses.

That being said, if you make a very skillful, spiritual and/or topical joke on HN you might be upvoted, I've seen it happen in the past (with things like poems, lyrics and other "not-so-serious" content).

Also, of all the points the author makes, this one is the only one IMO that's really applicable to HN so I don't think it's possible to draw a parallel between Quora and HN (if that's what you were trying to do).
This seems like a good idea, I know I often forget that a lot of people viewing a resource heavy site might not have the hardware I do.
Yes, this is what I'm excited about.

You can write Go code and compile it to JavaScript. You could create bindings for Cocoa APIs in Go.
Sure! To quote Scott's own TL/DR:

Quantum mechanics is what you would inevitably come up with if you started from probability theory, and then said, let's try to generalize it so that the numbers we used to call "probabilities" can be negative numbers.

That's it. So in QM you can model events whose probabilities 'interfere' with each other by canceling each other out (eg independent events A and B have 'probabilities' -20% and +20% respectively, but you want the 'probability' of either A or B occurring to be 0%), and do all other sorts of weird stuff.

Now why would you want to do such a thing is a whole different matter. But at least this should get you started.
I wrote a comment debunking OP's arguments, but it was too long for a HN comment and my noprocast settings kicked in so I can't post it as two comments; so I copied it over to G+: https://plus.google.com/103530621949492999968/posts/1PqPdLyz...

tl;dr: Let's summarize his complaints and my counter-objections:

1. no consent: irrelevant to whether this was good science or 'lousy social science'
2. crossed boundaries between corporations and academia: likewise irrelevant; also, welcome to the modern Internet
3. small effect size: misunderstood the statistical design of study and why it was designed & expected to have small effects
4. used LIWC with high error rate for measuring emotionality of posts: if random error, biases effect to zero and so is not an argument against statistically-significant findings
5. and LIWC may have systematic error towards positivity: apparently not an issue as negative & positive conditions agreed, and the studies he cites in support of this claim are mixed or unavailable
6. also, other methods are better than LIWC: sure. But that doesn't mean the results are wrong
7. maybe LIWC has large unknown biases applied to short social media texts: possible, but it's not like you have any real evidence for that claim
8. Facebook news posts are a biased source of mood anyway: maybe, but they still changed after random manipulation
9. experience sampling is sooooooo awesome: and also brings up its own issues of biases and I don't see how this would render the Facebook study useless anyway even if we granted it (like complaints #1, 2, 6, 7)

Now, I don't want to overstate my criticisms here. The author has failed to show the Facebook study is worthless (I'd wager much more money on the Facebook results replicating than 95% of the social science research I've read) and it would be outright harmful for Facebook to aim for large effect sizes in future studies, but he does at least raise some good points about improving the followup work: Facebook certainly should be providing some of its cutting-edge deep networks for sentiment analysis for research like this after validating them if it wants to get more reliable results, and it would be worthwhile to run experience sampling approaches to see what happens there, in addition to easier website tests (in addition, not instead of).
