Exactly.

There is not going to be a "one-size-fits-all" solution to this problem. A multi-faceted solution including both technical and non-technical elements would likely work best.

The easiest part of the solution to implement would of course be the text in the vicinity of the comment box. This text would establish certain core tenets that we can all vote on with Paul.

The technical aspect of the solution could monitor how often certain users are being down voted. The down-vote history of an account could then be used to "weigh it down" somewhat, so that it takes more up-votes in the future to bring their comment to a higher position on the page.
I think this is a very difficult problem to solve. I would love to team up with the right person, who has real, credible business skills.

However, I think this is just as difficult, if not more so, as a talented business guy looking for a programmer to partner up with.

There is definitely cross-over between the two; having a programmer co-founder that you can't take long to sales meetings is an opportunity lost. And if you can't discuss difficult problems with your business founder, you're also missing out. I fondly remember, several years ago, sitting down with my boss and explaining to him the problem I was working on at the time, and how, if I explained it without any technical mumbo-jumbo, he'd come up with solutions I hadn't thought of. That was really productive, and deeply satisfying for both of us.

I suppose where I'm going with this is that I think looking for co-founder should take more from the dating world than from the hiring world. Have a few meetings up front, test the waters with a few small projects before leaping in to bed together. Because let's face it: co-founding is another form of marriage.
Yeah Facebook was the last tech stock that was able to sucker in the "muppets". That's why Morgan Stanley & co jacked the price up as much as possible before running away like bandits
Angry Birds has an HTML5 version [1]. Also, the article said that no good browser games exist, not no good HTML5 browser games. There are some notable exceptions to that claim, one that springs to mind is Quake Live.

I agree, and with my apologies for the impending slashes, you can also go a little broader with the statement: There is design as visuals/aesthetics and there is design as problem solving/arrangement of a system. Integration of these two spheres is the key to great design.

In the field of web/app/interaction development, just as you say this largely comes down to the two disciplines you identified: Visual Design and User Experience.

In other fields, such as architecture or industrial design, the problem solving/systemic arrangement side includes additional concerns such as structural integrity, physical usefulness, manufacturability, maintainability, etc.

(And further, architecture places weight on the expression of values, which isn't as much of a concern in screen/interaction or industrial design.)

I think that with a bit of innate talent, both sides of this duality can be mastered and personal improvements made. It really comes down to practice, which in the end tends to be proportional to enjoyment and passion.

Lastly, it's the latter half of this duality that is somewhat similar to coding, or more accurately "pseudo-coding". It's not necessarily an effortless transition however: I can design logical systems and arrangements ADED, but attempting to translate that aptitude into coding skills is slow and painful.

Instead of focusing on multiple "real time" grocery lists, focus on figuring out what recipes someone often makes, what ingredients they have at home and do the hard work for them. That could be a winner.

I don't envision anyone doing their "meal planning" at the grocery store because they have to resolve the ingredient list with what they have at home.

But seriously, ditch the real time sharing stuff. I don't know why so many todo lists focus on that.

As I mentioned below, I've run a social network called Scribophile for about 5 years now. What I've learned is that you simply can't engineer away a social problem. People will always find a way to be jerks; the only way to mitigate them is either through:

1) Social pressure: the community must evolve in such a way that its members as a whole frown upon negativity. Hard, because it takes time and can go wrong. Or,

2) Moderation: a group of members you trust is tasked with actively deleting useless comments and threads and banning useless contributors. A zero-tolerance policy for stupidity. Is that elitist? Maybe. But an elite community is hard to grow when idiots are tolerated.

There is literally no way to engineer away jerks. A social problem requires a social solution.
A great post, especially since it seeks to get at the truth of something that has implications for future missions, at the risk of the OP's reputation.

This part is one of the more disturbing parts though, and a good reminder of why technical persons of all fields, whether rocket scientists or programmers, should not adopt a "Well, we worked hard and we're smart so I'm sure everything's fixed"

> What you probably don’t know is that a side note in a final briefing before Discovery’s flight pointed out that the large chunk of foam that brought down Columbia could not have been liberated from an internal installation defect. Hmm. After 26 months of work, nobody knew how to address that little statement. Of course we had fixed everything. What else could there be? What else could we do? We were exhausted with study, test, redesign. We decided to fly.

How is it that this mentality exists at NASA? Isn't it a matter of logic that if the foam was shown not to have been an installation defect, that the engineers have to keep looking for the actual cause? The OP just brushes over this but surely there was some kind of debate, like: "Well, the particular test claiming that the foam was NOT an installation defect was poorly conducted, and all our other measurements say that the installation is the likely cause, so moving on..."

I really hope there isn't some kind of "Oh fuck it, just ship it" mentality at NASA.
Maybe you could give some examples of those tools? I'm not asking to be snarky - I'm genuinely curious.

If the people submitting links have different biases, then the overall news site might not have any particular bias overall, even if individual stories do.
Apart from the content itself, I would suggest to place the guideline link more prominently. Maybe even at the top, directly before the "New" link.

To support this proposal: When I first arrived here (from your homepage), I didn't notice anything about guidelines until I stumbled upon a comment which mentioned them. Then I eventually found them on the bottom of the page (which can be quite long), where I seldom look at.

The way the blogpost details the process of using the spreadsheet is nice - giving one simple example and then scaling the number of stocks clarifies when this sort of thing would be useful.

However, it would have been nice to have a bit of explanation/background on how the PCA algorithm actually works.
i think you have the numbers wrong. at least in the supplement of our paper we say a petabyte would weigh ~1.5 milligram. It would be far too expensive to do that though; about 6-8 orders of magnitude increase in scale is necessary from current technologies. that said, we've seen that kind of drop over the last decade or so; here's to keeping it going.

I know lots of non-technical people. And I still think that if they wanted to learn, they could. I'm thinking of one friend in particular who avoided technical subjects as much as possible, studying history in college and public policy in grad school. And I submit that the kind of reasoning he has to do in public policy, and to navigate the bureaucracy of the State Department, is similar to the reasoning that a programmer does.
Didn't realize it was that close, but also I didn't go to ivy league :)

Can someone provide an example of an online community that has an appropriately positive attitude?

Hacker News is the most civil, useful and intelligent conversation on the internet, period. HN is easily two standard deviations less cruel or petty than any other discussion site you could name. The rest of the internet makes us look like Miss Manners.

I'm sorry that people weren't supportive of your personal projects, sw007. But do you have any idea how much worse things would have been on reddit? TechCrunch comments? God forbid, 4chan?

HN is an amazing resource and I'm glad to have it. The top comment is always 1) the other side of the argument being presented in the story or 2) information from someone on the inside (ie, "I work at fb and here is what is really going on"). If there's any online discussion site that's significantly more positive than Hacker News, I'd love to hear about it.
It's simply great. Any estimates when will the Python module come out?
> They can’t decrypt messages but they are able to track where everything comes from and where it is going. They can’t tell what you’re saying, but they have all they need.

He's talking about SSL here, right? For the record, this is completely incorrect. If "they" have access to a trusted CA (and circumstantial evidence says they do), they can MITM and snoop on whatever they want.

SSL encryption is not secure against state-sponsored attackers and sophisticated criminal enterprises.
Those figures are a bit misleading because they include a lot of the early development phase of a vehicle in the operational history. Is it fair to include, say, the safety record of the Model-T when considering the safety of a 2012 model Ford Focus?
Is it really an advantage? I know Tweetbot is the cool kid among the Twitter clients nowadays but others have been around a lot longer and I would assume have many more users (even if those users aren't still using the client).
Nice to see PCA in an HN article, it's a very powerful tool.

For those struggling to get the example in this article, I find PCA easier to understand given visual examples, and in less dimensions (try http://en.wikipedia.org/wiki/File:GaussianScatterPCA.png)

Note how this dataset is two dimensional in nature, and PCA yields two vectors. The first gives the direction of the greatest variation, and the next gives the variation orthogonally to the first.

An awesome use of PCA is for facial detection, a method called 'Eigenfaces' http://en.wikipedia.org/wiki/Eigenface

we printed the dna microarray using agilent's ink jet process (agilent is a spin off of hp; imagine an inkjet with actg instead of cmyk). each spot on the array has many hundreds of thousands of molecules. after we cleave the dna off the array, we take a portion of that, amplify and the sequence it. the portion we took off we estimate ~100 molecules for every oligo we made (55,000). we the sequence to get >55 million reads (so 1000x coverage); but these are just averages, and the distribution varies. you can check out the supplement of the paper if you are interested.

Zed is a master of subtle provocation (and not-so-subtle, if you are familiar with his other projects). I suspect that he doesn't actually think that it's easier to become a real designer than it is to be a programmer. But there's a certain amount of truth to the idea that one could pick up Photoshop, or a wireframing tool, or a bit of HTML and CSS, and start turning their ideas into designs much faster than one could learn enough programming to build a full application prototype. Working that insinuation into the title attracts readers.

There's nothing wrong with that sentence. I don't do those corrections, as in, I don't do that thing where you pedantically correct every little tiny "error" I can find. Got it smart guy?
Agreed, Twitter requiring you to get in touch with them should your app grow past 100k users seems like they're just setting a public limit for the point at which they want to vet that your application is behaving correctly.

From my experience with the Twitter API team, they've always been open and responsive, particularly with regards to a "Hey, I would like to do X with your API, is that alright?"-type questions.

I think Twitter have taken a lot of unfair flack from this announcement, when it seems like a really positive step forwards.

How do you avoid prosecution? Being in possession of child pornography is a crime. If you personally identified these torrents, then you are essentially confessing.

There is an interesting story in "Three Felonies a Day" where an employer discovers child pornography on an employee's computer. They contact their attorney, and the lawyer deletes the offending contact to protect the company. He then alerts authorities to the employee. The attorney is eventual prosecuted for evidence tampering. It's an absurd Catch 22.
Ah there you go, I sit corrected. It was free as of June 2002, so presumably for the last 10 years we could have been using it instead of Linux.

However, I would guess that had it been freely available when it was released in the early 90's then it actually would have more of a presence vis-a-vis Linux today.

An algorithm for tracking viruses (and Twitter rumors) to their source
I've posted several projects to HN, including both of my guides to programming and photography...and I have been extremely disappointed...with the LACK of harsh comments, and the more-than-deserved number of upvotes. And I mean that only half facetiously, because the critical ability of HN posters, on average, is quite high, so I half-expect people to be nitpicking and ripping on me...and that's fine, since I generally don't take it personally.

Obviously my case isn't apples-to-apples, since the OP may have pitched products that were attempting to be successful in a financial sense, whereas I just like showing personal projects. But my experience has been very supportive. This is not to say that OP is wrong, but just to say that whatever corrective measurements are being decided on, that you shouldn't go too far in fixing what may only be partially or rarely broken

The battery pack costs more than that, alas. The price may come down as the scale of recycling (and hence, the amount recyclers can pay for used batteries) goes up. The price per Wh for Li-ion has also been falling at a fairly steady rate. And of course, gas prices may go up.

We should also consider the depreciation of components in a conventional car that the electric drivetrain replaces. They should depreciate faster because they are less efficient and must deal with the additional heat they dissipate. They require an intake and exhaust system, complicated transmission, pumps, valves, lubricants...

I've tried to find other stats but I couldn't easily find more recent numbers. 2% is the lowest fatality rate I found. There are some statements at http://en.wikipedia.org/wiki/List_of_spaceflight-related_acc... but they're not changing the picture by much:

>> About five percent of the people that have been launched have died doing so. [..] About two percent of the manned launch/reentry attempts have killed their crew, with Soyuz and the Shuttle having almost the same death percentage rates.

I'm in the same boat as "mootothemax" - I would also love to team up with the right co-founder. Though, I'd want us both to do the tech and business work.

I'm not actively looking because I'm going to attempt to do the business work after I finish building my MVP.
Probably because they don't have a reliable way of differentiating one strand of the double-helix from the other, so matching bases are considered to be a single unit so that it doesn't matter how you've got the pair rotated.

I imagine this could be solved by ensuring that every helix starts out with something like a byte order mark that would distinguish the two strands reliably.

Storage density could be further increased by a constant factor if more kinds of bases were used, or if they could use single-strand DNA/RNA instead (which would probably require some chemical means of ensuring that a free strand doesn't accidentally bind to something else).
The feds conduct ongoing child porn investigations, not just passive enforcement. Once someone with CP is found, the feds often try to seize the provider in order to collect information on other offenders, which in turn leads to further arrests/prosecutions. And the cycle continues. I used to think Child Porn was rare. I was wrong.

We got completely different takeaways from this article. My takeaway tldr is: "don't stop buying our app just because the future is bleak". This statement struck me in particular:

> We’ll be working with Twitter over the next 6 months to make sure we comply with these new requirements as much as possible.

As much as possible? You have to comply 100%, I'm pretty sure Twitter won't be happy with you just making an effort. The new display requirements and the requirements not to include extended functionality nearly eliminate clients' ability to compete on anything other than just looks. Tweetbot features like Mute are going to have to go away.

I'm not doubting their commitment at all, by the way. I just read this article as a glass half-full perspective.
PCA goes far deeper than meets the eye. For instance, it's a well-known phenomenon that too much dimensionality can actually drive predictor performance to random, but PCA can mitigate that. It's a basically the bread and butter of practical unsupervised learning.
The author is basically using a linear algebra tool for creating orthogonal basis vectors of a matrix of stock prices. (The PCA is like eigenvector decomposition, but it works on rectangular matrices too. In fact, unlike many operations, it's very fast on unbalanced rectangular matrices!) Since these vectors are, by definition, uncorrelated, they can be very useful in building CAPM-balanced stock portfolios.

Using the PCA is great in this situation, but people often run into traps when using these sorts of spectral-decomposition methods on real world data.

The most obvious is that they try to interpret what the vectors "represent". Sometimes this is reasonable -- if you did a similar experiment on the stock price of energy companies, the strongest vector probably really would be closely correlated with the price of oil. But aside from unusual situations like that, interpreting the "meaning" of spectral vectors is a fool's errand.

well he's right, and his analogy is perfect. i once again in fact yesterday, had someone wanting me to build his business for free. after agreeing that i get a share of the revenue for cutting my rate in half and giving them my services, which are actually the result of 18 years of experience.

the point is, op is wrong in his belief that people will ever understand the value of what they ask for if they want it for free. lesson hard learned. i'm actually thinking about putting together an opensource contract that everybody should fork and edit to give a working framework to people that keep getting cheated over their expertise.

but, i completely agree with the article itself.
Whether you personally like an argument or not has no standing on its validity and strength.
There's plenty that can be done that never involves having to look at an image yourself.

For instance, if I gave you a specific file name/size/hash (but not showing you the actual image), could you find out who possesses it, is distributing it, and anything about their location or identity that would aid law enforcement in catching the bandit?
