Doesn't look like a misquote to me. And while, yes, unit economics are a thing, there can be a huge gap between being unit profitable and profitable as an organization. A bunch of delivery companies flew into the ground during the first crash under the same circumstances (including a few grocery delivery companies).

If you're running a company with 500 employees an a big office in San Francisco (where employees average ~$100k a year, fully loaded), and each of your deliveries nets 1% of a $50 order, on average ($0.50; not a ridiculously low net margin for the grocery industry, even in logistically optimal scenarios -- which delivery is not), you've gotta be doing (500 * $100,000) / .5 = 100 million sales a year just to break even. AKA, $5 billion a year revenue run rate.

So then you say: "OK, we'll just cut some of those expensive SF people, and we'll bring the curves closer together!" And that could happen. Or you could discover that getting those margins was only possible with X million sales a year, and getting those requires at least 500 employees to run operations without dropping the ball. And then your investors stop throwing money at you, because the business economics look scary, and the funding climate has changed. And then you die.

Again, this is not a made-up story.

When huge investors get involved in land-grab businesses before they're profitable, they're all betting that their horse will be the next Amazon. But there's only one Amazon. And even Amazon isn't that profitable. And Amazon started by competing in a high-margin industry.

The blog post is a great overview as well as useful context, thanks for sharing it.

TL:DR summary: Scientific results are highly contingent on subjective decisions at the analysis stage. Different (well-founded) data analysis techniques on a fairly simple and well-defined problem can give radically different results.

It's very interesting research -- a great real-life example supporting the models Scott Page et. al. use for the value of cognitive diversity. The thrust of the blog post is about where crowdsourcing analysis can be helpful (as well as reasonable caveats about where it might not apply), which is certainly an interesting question. Obvioulsy, there are a lot of other implications to this as well.
I don't think limiting searches categorically has ever been a problem to this extent before (big statement, but maybe?). Because there's never been a broadly-used impediment to the types of searches the government typically conducts that simultaneously requires a sacrice on the part of individuals if it is not available.

Or to turn it around, what has the government historically desired to legally do after obtaining a warrant that it has been unable to do?

We never made locks or strong doors illegal. The closest would probably be mandating log retention at telecom providers for a certain period of time.
Another potential explanation is that kids with high empathy spend more time socializing, which is partly why they have higher empathy. And kids with lower empathy spend less time socializing, and more time on subjects they can do themselves, like math.

Note that the effect of socializing -> higher empathy -> better at socializing -> enjoys socializing is a feedback loop.

I suspect that would depend upon whether they "cared" for the welfare of the individual they could read or if they "used" that info against them.

I personally don't think there is a clear line between those two things. I have known many people with natural social skills who routinely used them to influence social settings to their personal benefit, often without being particularly noticed by most of the people involved. I think it is more complicated than a simple binary choice.
I should also mention that my graduate program (top-tier in its field) unofficially required all students to publish in a top-tier journal to be allowed to graduate with a PhD. It was unofficial, but enforced by all the professor/advisors. If you didn't publish in a high enough journal, you'd end up in 7-8th year with a long thesis and have to leave with a master's degree.

> Am I being silly, or could a hard drive full of random data be confused with a hard drive full of encrypted data by some member of the security services in the future? Would zeros not be a better bet?

I was under the impression zeroing, well, didn't fully zero—specialized tools can recover the former bits. If you write a truly random stream to the drive, it's much harder to recover the former bit versus the new, random one. To my understanding it's the same reason why XORing one-time-pads are utterly effective as a form of encryption (and you can throw away the pad).

if this hypothesis is true then does that cast a shadow of doubt on their method which involved using a questionnaire given to the parents of the children to rate their empathy and systematizing ability. if social bias can hurt children's math ability then surely it can also contaminate the survey results.

Considering that much of what's on people's Facebook pages is against the law to even ask about (in some jurisdictions) it's probably a wise choice. Stick to what's provided by the candidate. I provide a link to my LinkedIn page on my résumé, but nothing on it touches on areas I know would cause problems. Most of my coding is in private projects so I generally don't bother with listing my GitHub.

For example, I know that where I am it's against the law to ask if someone is married during the hiring process and that's pretty clear on many Facebook pages.

Exactly. Bird statistics don't mean anything in this case because jackasses are flying the drones in "interesting" areas rather than random areas.

Having to have an FAA license that shows you understand airspace and its laws is not an undue restriction.
This confusion is why explicitly using logical quantifiers is preferable: `exists x. x` is (isomorphic to) the top type (if there is one), and `forall x. x` is (isomorphic to) the bottom type (if there is one).

Submitted title was "Empathy and social skills found to be negative predictors of mathematical ability". We've changed that to a quote from the abstract. I'm not sure the two are different enough to justify calling the first one linkbait, but it's better to stick to language from the article.
I agree, a better process than voting would be "evaluate the advantages and disadvantages of each practice and determine which results in the highest quality, most maintainable code."

But since when have we been any good at identifying future needs or identifying maintainable code? Just be consistent, try to at least leave SOME documentation for the next guy, and don't be actively malicious.
@jacobolus is correct IMO, according to these data, empathy can't be described as predictor of math ability.

See http://www.nature.com/articles/srep23011/figures/1

An outlier group of mathy kids turn out to have poor (but not the poorest) empathy skills. The rest of the cohort isn't skewed, at all.

You say that not everybody can downvote, butyou forget to mention that nearly everyone can upvote.

A downvoted post needs someone to downvote it, and then for nobody else to upvote it.

People shouldn't downvote for disagreement, but they do. It's probably more important to upvote grey posts than complain about downvoting.
Here is a paper about it:

http://www.vidarholen.net/~vidar/overwriting_hard_drive_data...

"The purpose of this paper was a categorical settlement to the controversy surrounding the misconceptions involving the belief that data can be recovered following a wipe procedure. This study has demonstrated that correctly wiped data cannot reasonably be retrieved even if it is of a small size or found only over small parts of the hard drive. Not even with the use of a MFM or other known methods. The belief that a tool can be developed to retrieve gigabytes or terabytes of information from a wiped drive is in error."
Is it just me, or is the return missing in the `function` (or am _I_ missing something :)?
Not important of course, just pointing it out...

Video chat systems/protocols look to be somewhat stagnate/immature. I just wanted to do 720p 30FPS screen sharing across the internet (Europe to America), and this can be done with $10,000 dedicated hardware encoders and a ridiculously expensive mile for mile dedicated layer 2 network route.

-OR-

Alternatively, we could purchase a ~$200 elgato HDMI capture box, and create a free youtube account to stream 60FPS 1080p across the planet.

Currently there is no in between for high FPS video streaming systems on the internet.

There's also https://jitsi.org/ and https://obsproject.com/ , but they don't seem to allow P2P connections with buffering options. The trade off for low/unreliable bandwidth is allowing larger buffers which would impose greater latency.

I agree it's frustrating - and I've been on both sides of that fence - but still... it always puzzles me when someone seems to get worked up over the fact they didn't seem to get the callback they expected even though they had been told they were probably good enough. Why do people simply forget about the possibility that someone even better showed up right after them and got the spot instead, and rightfully so?
It doesn't (necessarily) mean you were bad, or that they lied to you, or anything of the sort. It might just mean they had other candidates who fared even better.

Also, in these cases, I'd recommend you simply call back yourself. Think of it as the opposite of the judicial system (for the US and most of Europe, at least): the burden of proof is on the prosecution. In this case, it's on the job-seeker. You're the one who has to show you want the job and that you're the best fit. The company's role is to find a good fit (and to do so by using their resources in a reasonable way).

That being said, I wouldn't advise on doing "homework" assignments that are exceedingly long.

For the record, when I am on the recruiting side of the fence, I always do a phone screening first, with live coding in a shared editor. Only then might remote homework or on site coding come up, and I always tried to make sure the effort is minimal. It's hard to find something that fits all people and minds though. Try to design a recruiting scheme, and let me know how it works out and if it doesn't piss anyone off. :)

The courtesy thing is another issue entirely, of course, and obviously a lot less defendable...
No one is entitled to the job they like. If people won't pay for your goods and services, you need to find another job.
> As lmm said, you don't need to keep track of the score, just play the move you think gives the most points.

In a way, I think this is where AlphaGo draws its greatest advantage. Being a computer, it always knows exactly how well it is doing, since it can constantly be counting the board with perfect accuracy.

With this ability, it is capable of playing the absolute "safest" moves, taking half a point here, half a point there, when it knows it is leading. Whereas a human might not even know if they're leading, forcing them to take "bigger" moves to get more points, since they can't as easily be accurate down to the 0.5 point precision.

I recently spent 4 weeks of my life interviewing for one of the bigger video games companies for their web dev team.

After those 4 weeks, I didn't get the job. Around the 3rd week I felt like my time was wasted. I want to work for this place, but if I want try again later in life, I probably won't because it took up way too much of my time with little to no value.

It sucks that I'm required to sacrifice my personal and vacation days to find potential new employment.

You are completely misinterpreting my remark. I in no way was discrediting the study based on three data points. I was interested in reading it because of three data points, but I don't really have the time for it. Fortunately, someone else read it and found a glaring flaw and that is sufficient for my personal level of interest at this time, thus I won't be wasting my limited time on this today.
> So, the passage explains what contribution margin is, but TC is talking about being "contribution margin positive".

TC has a terrible reputation for using business terms that aren't really generally considered business terms.
The hole concept of end to end encryption works far better if the ends are actually secure. We use end to end encryption to protect our communucation one the move and our endpoint are protected with secure hardware.

Weakening end point security is certantly not as bad as going after tls (for example) but its still a vital piece of our trust chain.

And the smartphone will grow in importance as an authentification factor and that makes it even more vital.
I didn't see your response for a long time.

"That's a nice shirt, I really like it!"

vs.

"Hey, that shirt looks good on you now, but I bet it would better on the floor of my bedroom!"

are two ways to say that you like somebody's shirt. One is a workplace appropriate compliment, one is obviously not.

A policy like "even complimenting your coworker's clothes can be reported as harassment" isn't some trap designed to catch you and punish you for the act of being friendly. It's a policy that's designed to defang institutionalized harassment that persists under the guise of being friendly; by couching sexual come-ons or derogatory remarks ("I always like the shirts you wear, they're by far the best part of having you work here" is a compliment for the shirt, and an insult to the person wearing it) in the form of a back-handed compliment, disgusting people can then claim that they're being punished when all they wanted to do is be nice.

If you still don't understand my point, please let me know and I'll try to explain it further (:

> Then, in the courtroom, things don't get any better. First off, the court room will not be a federal one, but a state one. Since you didn't register your work, you can not sue in federal court and, thus, will only be eligible to receive either the amount the infringement made or the amount you lost, whichever is greater. Sadly, in many, if not most, copyright matters that amount is equal to exactly zero.

That seems to imply its still the strongest evidence.

Yea, work does not need to be an RPG. That's just lazy administration. I think it happens eventually with most companies over a certain size, they can disregard the little things, or I guess they stop having the need or ability to address the finer things of human interaction.

I think it could be argued that information is best kept at a need-to-know-basis, but I think that also is a cold strategy, you know, not very endearing (who needs to work to be nice). Or it could be a trade off against pedagogy. Not everyone likes to have their hands held all the time. Then again this is just day one.

Abstraction? Is it that the size of a company is in proportion to how dry and abstract its thinking becomes?

I use GNU troff (Groff) for maintaining this.

And by the way, this is actually installed as a man page on target systems.

Most of my struggles were in the area of halfway decent HTML conversion. To that end, I started with a very hacky C program calld man2html, which actually contains a mini-troff implementation, and improved it quite a bit. I cloned that program here:

http://www.kylheku.com/cgit/man/log/

This had numerous issues, among the main ones being not handling loops and conditionals and so on for complex macros.

I still do quite a bit of post-processing on the output of this program, still, to do things like re-arrange its order, add internal hyper-links, and create a Java-scripted table of contents:

http://www.nongnu.org/txr/txr-manpage.html

(Almost the same URL as before, s/pdf/html/).

That post-processing is done by:

http://www.kylheku.com/cgit/txr/tree/genman.txr

I don't like the approaches you have to take in troff for defining multiple ways of doing the same thing, based on whether it is juxtaposed to something else or followed by whitespace. This is fundamentally broken.

For instance if you want foobar such that foo is italic, but bar is regular, you have to use .IR foo bar, rather than the .I macro. I'm sorry, but a markup language should have the scoping/delimiting wherewithal not to have to do stupid things like this.

I have a more or less fixed (non-growing) set of such redundant macros in the document and so it doesn't bother me that much any more.
