And wearing a tin foil hat just makes you a better reflector!

Anyway, if you look up through-wall radar detection, most of the implementations use S-band radar, and it is probably safe to assume that it's already been figured out how to use wifi stations and devices already in place emitting signals to each other, rather than always needing to bring additional equipment.

With regard to privacy though, it seems like it would be data and computationally intensive to track the movements of people in a large number of houses.

Let's say that a hypothetical application could only detect velocities away from or toward the base station, but no directional information. With each movement you make it would build a set of hypotheses about your location. Then when you make another movement, it would need to branch out, and create an entire set of hypotheses for each hypothesis in the previous set, and so on with each movement. While the program could abandon entire branches when they showed you walking through a wall, it would still grow very quickly.

Though it is possible to mine data of cell phone locations and CC television cameras after the fact, it seems like (if my understanding of how the technology would work is anything near reality) it is simply too difficult to collect a lot of information about people's movements in their homes without a specific prior reason to justify the expense.

Anyway, perhaps rather than tinfoil hats, people worried about surveillance should hang lots of mobile sculptures in their houses to create confounding noise instead.

So jSX is a language that compiles down to js? Looks like its supported in Chrome but can't confirm any others. If so, you should make a note in the docs, not sure many devs are familiar with JSX.

Design looks fairly similar to Misfit Wearables (http://misfitwearables.com/). Not quite as sleek but I don't expect the user to complain.
The "where do we want to go and when?" question isn't the hard part, though. It's finding venues and flights with the best group rates and windows. It's not so much the front-end logistics and discovery aspect that's challenging; it's the back-end logistics. Especially as the group increases in size.

I don't think any app is going to effectively take choice and discussion out of the equation. Attempting to do that, especially with a category like leisure travel, is asking people to let an algorithm plan their vacations. Most people won't go for that; they want a large degree of choice and consideration in the process. But the stuff nobody likes doing -- planning flights, searching for fares, booking rooms, etc. -- is where the pain points reside.

Not every commuter takes the subway to and from Penn Station. The surrounding area has a lot of offices, so many people take light rail there and then just walk to and from work.
I have learned both languages in the past year. Objective-C is better in most ways (and not in a few others). But that doesn't matter.

If you're serious about mobile right now, you really have to just get over whatever is holding you back and learn Objective-C. If you don't, you won't be able to write apps that can use the camera, load quickly, feel native, etc. And the big one is that you won't be on the App Store. I don't think this is going to change anytime soon, and it wouldn't be good for your users (if and when you have them) if it did (power consumption, look and feel, access to the accelerometer and camera, etc. all matter on mobile).
The fitbit aria scale had a clever way to set itself up. As far as I could tell, it had my computer join a known network, and broadcast the SSID & Password that my computer already knew off to the scale. So the scale gets put in setup mode, and listens for that temp network.

At least that's what it appeared to be doing when I set it up....
We've recently moved from Pivotal to GreenHopper (Jira) and every single engineer wants to go back to Pivotal. We've given GreenHopper a couple of months to give it a fair chance, and in every way it's clunkier and more confusing than Pivotal.

I'm not quite as ready to jump into HN attack mode.I immediately wanted to buy and/or help this company somehow. I've literally stayed up worrying about my dog because of lack of intel. But you're right, the intel is not quite there (yet).

I have 2 chocolate labs, and immediately was thinking how amazing this is as one is getting older - however, I'd like to think I am an 'attentive' pet owner (if not over-attentive by my wife's standards).

Your point about what the device can/can't discern is important. That is where I hope to see this go. Unfortunately for pet owners, your dog often doesn't communicate with you very well regarding their health. Sure, weight is relatively easy to discern, as are superficial wounds. But infections, arthritis, skin/coat health - all could be studied to give an owner insight if it is time to visit the vet. Ala preventative medicine.

Too many times an unusual throw up, limp, sleepless night can cause a vet trip and be nothing, but even slight trends could tell you a lot about the dogs health.
This always bothers me when I'm interviewing. I've gotten the "better suited candidate" as well as the "lack of experience" and "not right at this time" excuses. How does that help me in any way as a job seeker? I am, in some way, "not right" for the position. How? Too shy, or too forward? Too young or too old? Experienced in the wrong technologies, or not experienced enough in the right ones? Or both?

This just leads to depressing frustration. I want to improve and be the right candidate, but I don't know how and no one will help me figure out how.

Luckily, I have a job now. But God forbid when I have to start the interviewing process again.
Balanced has always inhabited a nebulous void of blatant-copying-with-one-novel-new-feature territory for me.

It's clear they just copied (with permission? consent?) the public interface of Stripe. They tried to copy the documentation format (layout, style, presentation) too, but it came off kinda poorly (margins, people. margins). They have public test cards/accounts, but they fail to test correctly because they get "used" and can't have multiple actions performed against them. Then, there's the whole ID thing. Why the fuzzy heck would you use ugly, long, probably-going-to-run-off-my-screen URIs as IDs instead of short IDs? They advise you to never construct your own API endpoint URIs from shorter IDs, except that's exactly what they do all throughout their documentation.

But, Balanced lets you pay out next day and Stripe holds your funds for 7 days before allowing payment. So, Balanced wins on time-to-pay speed (and they have same-day transfers to Wells Fargo). Though, with Stripe I assume you could eventually have enough of a float in your account to pay out next-day under your own prior funds.

From my complete outsider point of view it feels like Balanced is full of slightly subpar copy ninjas. (obviously just on their API, documentation, and front-end presentation. Their backend could be amazing or it could be meter high jenga code.)

We're discussing two issues. First, there's the issue of granting minors basic legal protection from unwonted sexual material and sexual advances. Second, there's the issue of coddling them and not properly educating them about sex.

The first issue is not necessarily synonymous with the second. Sex ed in this country is certainly inadequate. For example, many school districts continue to teach abstinence-only ed, despite dozens of studies showing that it doesn't work. The solution is to focus on improving children's access to sex education while granting them basic legal protection against sex offenders.

Children don't have to choose between being coddled or protected from abuse.

Matt, do you have any insight into whether or not there's even any internal discussion within Google about revisiting the XMPP issue regarding Hangouts, and/or publish a spec for their new protocol?

Of course I totally understand if you either don't know, or aren't allowed to comment. Just curious if it's something that's even a point of discussion or if everybody considers the issue closed, done, over, fini...
It is agreeable. I am waiting for them to first merge Google Voice to Hangouts. XMPP also needs to up its game and support these extra functionalities.
Looks like the HN backend needs another stealth founders-only feature: highlight known troublemakers to remind people to probably not interact with them unless you know you can win a pet argument.
Ah yes, I see your point now. A couple of centuries after the first Henry V, there’s another Henry V, born in England.

Of course, there are plenty of kings and child brides to choose from. How about Richard II of England, who married Isabella of Valois when she was 6 years old?

I think a better plea would be for Google to release Hangouts as a protocol.

I really hope they do this. And, truth be told, I'll be a little bit (but not totally) surprised if they don't. Google have, despite some recent criticism, been fairly good about supporting open standards and protocols in the past.
I think you should pick based on your primary use case, i.e. whether you are a merchant (stripe) or a marketplace (balanced).

IMO in a couple of years the offerings from these two companies will be so close that this distinction won't matter, but for now they are converging in from different directions so you should choose appropriately.

(I feel this is a lot like Box vs. Dropbox. One started from the team/enterprise side, and the other from the personal/consumer side, but now Box offers free 5GB for personal use, Dropbox offers dropbox for teams etc. A couple of years back, it mattered which one you picked depending on your use case, but these days not so much.)
"Tell a Christian that Jesus' mother, Mary, was probably 13 years old when she became pregnant, and they freak out as well."

"What makes the robot wicked fast is the fact that it's got four independent drive motors, each one of which has a power to weight ratio that's absolutely bananas. Only 6 millimeters in size each, the motors output 1.5 watts of power at 40,000 RPM, driving the individual whegs through 16:1 planetary gearheads. They're not cheap (hundreds of dollars each), but they make for one crazy little robot. And of course, independently driven whegs make the robot smaller, lighter, simpler to steer, and generally more efficient overall"

What are my current alternatives if I want to build something similar and I'm only willing to spend say $50 per drive motor?
Is this research on Roundup as damning as it looks?
I started reading this paper [1] on the effects of glyphosphate and quickly realized that I'm way out of my depth here. The claim they make is very bold, basically that glyphosphate inhibits a critical enzyme (Cytochrome p450), ultimately leading to many of our modern diseases through a process that damages gut microbes.

While I'm not a fan of glyphosphate or the model of agriculture it supports (for other reasons not relevant here), I don't know anywhere near enough about biochemistry to know whether there's any merit to this paper's conclusions. Are there others in this community who can shed some light on this?

Wow - I wonder if it would be possible to practically use this to commute to / from work every day.

And, don't forget the rather nasty consequences of Amazon's ability to operate on no margins: it kills all their competitors who have to actually profit to stay alive. When Amazon moves into your market, your company is probably in big trouble. Really, thats good in the very short term (lower prices for consumers), but bad in the long term (because once amazon controls everything, theres no reason to keep their margins so low).
> I meant any logical model of what an API does,

Gotcha. You're right that I got this wrong, but I think my objection still stands; a peer-to-peer interaction model is still not RESTful.

> Its obviously a problem for every request to navigate from the API root if you have tight latency constraints,

Even in truly RESTful systems, 'every request' wouldn't navigate from the root; the first interaction starts there, but it's not like you keep going back to the root every single time you want to do anything.

> In fact, reducing latency by encouraging cacheability is an explicitly-cited motivation for REST.

Absolutely. I was thinking of the 'layered system' constraint. From http://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arch... :

> The primary disadvantage of layered systems is that they add overhead and latency to the processing of data, reducing user-perceived performance.

You are right that caching helps balance this out, but not everything can be cached; for example, a first-person shooter game would be hard to cache.

> A is a client consuming an API and B is a server providing an API.

Even if it's 'oh they're just two different APIs working together', it's not a singular API, which is what we're talking about here.

Why not? Having clients with a range of functionality is how the entire open-standards world works. Somehow, the world wide web continues to work just fine even though it's possible for people to use any browser they want.

If a user has a third-party client, and it doesn't support some fancy feature that the first-party client supports, that doesn't seem to be a big problem. I don't think a significant number of people would care if using video conferences required the official client.

Speaking from the perspective of the nation-state power structure, "This is a bad thing ... how?"

EDIT: To clarify, I'm not advocating this. I'm saying that the UN pointing out that surveillance correlates negatively with freedom of speech is not something most nation states give two shits about — specifically including many of those that talk a very good game about freedom of speech — and many of them probably think it's a good thing.

" I know people who ask "how can I run more?" and I ask "well, do you enjoy running?" and usually they say they don't. I don't tell them they need to buy different shoes or gadgets to try to coerce them into doing it, I suggest they look at other kinds of activities that will fulfill them and try to incorporate that into their life. "

Interesting! But isn't our natural tendency to be lazy, why would anyone prefer to stress themselves rather than sit infront of TV? Shouldn't we just continue running, irrespective of whether we enjoy it or not in the beginning, until we start enjoying it?
You're more than welcome to use XHR however you see fit. We don't dictate that choice. For many that will mean `$.ajax` - React plays nicely with jQuery (so long as you don't modify the DOM out from under us). For others that might mean a thin library that does that the same thing.

If you're interested in using jQuery with React, we have an example: https://github.com/facebook/react/tree/master/examples/jquer.... It doesn't use XHR but it should give you some idea of how the 2 can play nicely together.

By that standard, the guy on the bus who tells me about lasers from outer space that make his legs hurt when he talks about the government . . . he's a fair representative of "most scientists".

If you want to take random encounters with people on the street as representative of a philosophy, you have to at least go to a place where that philosophy is practiced. To talk to the 'average scientist', you'd better at least be looking for him on a university campus -- better at a conference somewhere. To talk to the 'average Christian', you had better at least be looking in a church.

It's not just a sampling issue; those groups also police their membership. What you want to take an average over is not people who declare themselves 'hackers', but people who the community of hackers agrees are 'hackers'. Best way to do that is go to where they meet.

Ask HN: How to write the first line of code in a new startup?
My friends and I, are starting to create our own startup, we have no intend on revolution the world but some of our idea seems to be interesting enough to try.

My main goal, as a developper is to provide a great start for our idea. But I'm facing an interesting question.

How do I write my first php line of code. I mean, I'v started plenty of little project but what make a startup a great startup?
What is the first thing you need to do when you'r the developper?
And the secondary question, there probably many technological challenges so does startup rely on framework (and trust other) or prefer to use a custom solution?

Oh I agree. I guess I thought you were referring to a lot of these "comprehensive social trip planning" tools that help you collaborate on a trip. I think they are useless. I agree it's the problems like "ok, how do we get from Prague to Vienna" now that me and my buddy decided we want to go that are truly the hard part.
I believe maeon3 intended to reply to jacquesm by using jacquesm's past twits, but ended up responding to you.
I guess I can't agree. In light of the delicacy of the subject matter, the question seemed designed to stifle debate.

OC made several claims about which respondent could be asking for a source. I'll assume it's the claim that the reactions of other people causes the "damage" since that claim's implications are most relevant. To which I wonder: Can respondent provide academic sources demonstrating that societal or cultural response doesn't exacerbate (or largely cause) victims' feelings of acute horror?

I have a couple of impressions about this. The average person isn't all that good at understanding where their feelings come from or separating whether they come from a specific event or the culture's evaluation of the rightness and wrongness of that event.

I also notice that academics often have a hard time getting funding for things that might have unpopular results. One only need to review the comments section of any article that mentions pedophilia to know that citizens are united on both sides of the aisle regarding how we should feel about it.

Unfortunately, most of our judgments in life still have to be made without the benefit of academic sources, simply because the number of such sources are rare and ambiguous signposts on the vast territory of decision-making we trek through. Instead we have to turn to other means of rationality.

I happened to come across an interview with one self-aware victim who was able to separate the event from society's reactions to it. This kid Jody Plauche was molested by his karate coach. Later, after the coach was in custody, his dad Gary Plauche shot him to death.

http://en.wikipedia.org/wiki/Gary_Plauche

ESPN had a good article about the case in which they interviewed Jody.

And how did the boy feel? He was angry -- at his dad.

"I didn't want him dead," says Jody Plauche, now 40.
"I just wanted him to stop."

Jody went on to be a four-sport letterman in high school,
but the most important thing he's done is teach parents
how to reduce the risk of pedophiles such as Doucet and
Sandusky molesting their kids, through his work at a
victims' services center in Norristown, Penn.

"I got a letter once from a woman, who wrote, 'I told my
daughter if somebody ever touches you inappropriately,
it's not murder. It's worse than murder. It kills a
child's soul.' So what's that little girl supposed to
say if she ever gets molested?" says Plauche. "She
doesn't want her soul to die. So she doesn't tell
anybody."

Jody's dad made the same mistake.

"My dad was absolutely too extreme," Jody said. "He used
to tell people, 'If anybody ever touches my kid, I'll kill
him.' I knew he wasn't kidding. That's why I couldn't tell
anybody. And that's exactly what he ended up doing."
