Hey, I'm with Mapzen, let me know if you have any questions. We're importing GTFS feeds from multiple transit agencies and serving them via a single API via our Transit.land project. We then pass the data into Turn-by-Turn, our open source routing engine which serves them up as data tiles. We select routes with on-the-fly costing and draws it via LRM (Leaflet Routing Machine).
Why not simply out of curiosity ? People have a tendancy to assume tech people are men, or that people on the internet are men. I myself always picture HN users as 25-35 y.o white men with a beard and glasses. The Silicon Valley stereotype.
Sometimes it's interesting to get a picture of what the HN community is actually made of, without any other conclusion than "oh, ok."
My collision code is in Rust, actually. Pretty funny.

Capsule-plane collisions are pretty simple, simple enough that I can outline here. The first thing you want to do is find the sphere on the capsule to perform the test on, call this time t_X. Create a line from the segment (starts at t_0, ends at t_1) bounding the capsule and determine its intersection point with the plane. If there is no intersection, just set t_x to mean(t_0, t_1), or halfway on the capsule's segment. If there is an intersection, and the time is between t_0 and t_1, set t_x to that time. Otherwise clamp it between t_0 and t_1.
Now you have a sphere and a position (the time t_x on the capsule segment), and you can perform a moving sphere - plane collision.
This algorithm works because the premise - the point on a capsule closest to a plane will always get closer to the plane, unless the capsule is moving away - is sound, as far as I can tell.
If you call that science.
>"Decided to move" is not a reasonable description of the reasons for people to move into cities - they want jobs, they want to live among their peers, they want to take their place in the world. They didn't "decide to move", as if somehow they could live in their hometown all their life achieving their dreams.

That's still a very privileged view. The predominant reason people move is for work: they'll be (or continue to be) unemployed if they don't.

David King, AirBnb's new director of "diversity and belonging," says AirBnb is aware of discrimination on their platform and they want to be a leader in addressing it. He says he's talking with Luca and others in finding potential solutions.

One thing that could help is removing people's names and photos or making them less prominent. But this isn't something AirBnb will improve their platform.

"The photos are on the platform for a reason," King said. "It really does help to aid in the trust between the guest and the host . . . You want to make sure that the guest who shows up at your door is the person you've been communicating with."

The suggestion of Kristine1975 upthread works though. /usr/bin/git just runs xcrun to run git from a command-line tools or Xcode installation. Since Xcode is a regular application:

It's kind of thought provoking to apply the definitions of religion in a logical manner to movements like string theory, or LGBT movements, or even programming cultures in addition to traditional religions like Christianity. Essentially if there are beliefs and practices which are beyond questioning at the risk of violating taboos and social ostracization then you get a form de facto religion. Not that this necessarily makes these things wrong, but it does carry consequences and should be realistically scrutinized by the public. At least if I become religious I prefer to knowingly choose it or be aware of it -- e.g. I'm Christian and chose to be so including accepting certain intellectual dissonances. Personally most of those intellectual dissonances have provided more areas for me to grow in deeper understanding of the world (vis-a-vis my world views). In physics I keep an eye on similar dissonance like the current non-compatability of quantum mechanics and relativity at mixed scales. Or that new EmDrive which could prove valuable insight into physics... However, since social beliefs also follow physical laws and result in consequences (I consider it as a multivariate game theory problem where different religious beliefs and axioms will produce different optimal outcomes -- though we rarely live up to the optimal solutions). Look forward to reading Durham and see if the views offer more clarification.

Actually, I don't think that will work. I understand that the increasing wages for education over the past decade have been a chimera. In fact, those wages have been stagnant compared to economic growth in the USA, while others wages have fallen. So there is the impression of higher wages for more education only because we look at wages relative to other peoples wages.

In addition, I think the requirement for education for everybody to do well just doesn't make any sense for a society as automated as ours. We should be able to have a great life for everybody - with much fewer requirements that everybody get advanced degrees. Our focus on education is a symptom of our broken economic system.

I know the difference between rent control and rent stabilization. I wasn't saying there weren't units under regulation, I was just speaking specifically rent control. Rent stabilized units are mostly a short-term deal as the unit distribution changes within a building and their prices approach market-rate.

We did not exactly get a fair shake when it came to those trade deals like NAFTA that Clinton signed back in the 90s. It hollowed out all the decent jobs in manufacturing that were supporting families in this United States.

I am not arguing for protectionism, but just go and try to do business south of our border in the same way they do trade with us. The trade deal is not symmetric on both sides.

People who craft these trade deals do some in secret, just look at the TPP deal going on now that is very controversial. Then the deal is rammed through approval, and there is little transparency.

How about making things a little more transparent? How about letting the public take a peak and have a little more time to digest what is being written?

In the 1980s there was a hype of one and two blade designs.

I always found the one blade designs most fascinating and vividly remember a video of the three one blade rotors of the Monopteros 50. Each blade was 56 m long.
There was also GROWIAN, a two blade design with 100 m diameter on a 100 m tower.

All of these projects were abandoned and the towers demolished. The three blade design has won for the reasons you stated.

I searched hard for the Monopteros video but there isn't even a good picture which shows all three towers. By-catch:

The FDA already regulates other forms of nicotine (patches, gum, lozenges, sprays, inhalers).

But, since you are opposed to the FDA in general, then I think our discussion of the FDA regulating this nicotine product is not productive - our disagreement is not on any particular aspect of this particular drug, but in the existence of the FDA, and regulations in general. You object to all FDA regulations, not just nicotine. That is a much larger discussion, which I don't particularly want to engage in right now.

Paul Graham deeply misunderstands the argument against inequality, and he's also dead wrong that starting startups is what makes most people reach. Most wealth is institutional and/or based on rent-seeking. Starting startups is not rent-seeking.

> I guess I'm a baby boomer. I was born in the 70's.

You're Gen-X, not a Baby Boomer. Lots of generational discussions these days focus on Millenials vs. Boomers and ignore Gen-X entirely, but insofar as the contrasts drawn have validity, Gen-X is in many ways a lot more like the Millenials than the Boomers.

> I was a kid during Vietnam war, and Korean War.

Unless this a technical reference to the fact that the Korean War never formally ended, this contradicts the preceding: the armistice which ended the active phase of the Korean War was signed in 1953. If you were born in the 1970s, you weren't a kid during the Korean War, as that term is usually used.

> At least don't include my generation with my father's. My father was a real baby boomer, but he was born in 1938.

Baby Boomer refers to the post WWII baby boom, those born 1946-1964.

GetCloak.com | Hourly Contract | Remote (we're in Seattle)

Cloak is a VPN network, and a set of apps (currently for iOS and OS X) designed to connect to this service.

We are looking for a senior Android contractor to help us get our native Android app off the ground.

Right now there are just two of us developing the service. We differentiate Cloak by (1) providing a beautiful minimal UI and features like auto-secure that allow the VPN to fade into the background, (2) actually caring about the secure construction of our apps, our APIs, and our VPN network, and (3) going the extra mile, and then another, for our customers.

Our ideal candidate has:

1. Deep experience architecting complex new Android applications, and an innate understanding of the pieces that need to be put together to provide an experience that matches our current iOS and OS X apps.

2. A keen sense of how they might build and interact with OpenVPN under the app's hood, how they can implement auto-secure reliably, how they can gracefully handle captive portal networks, etc.

3. A curiosity about VPN networking, and an attention to detail to ensure that every security-critical decision the app needs to make -- from credential storage to networking configuration -- is made well.

4. Experience with modern Android development tools and practices: for example, our ideal candidate is probably running Studio beta 2.1 right now, is perhaps wary of using Fragments, already planned to start this app with appcompat, has played with or even used dagger2, retrofit and rxjava, butterknife, etc.

5. Ideally, a love of graceful UI designs, and a willingness to make pixel-detail changes or tweak animation curves when it just doesn't feel right.

This is a meaty project and we think it will be a fun challenge for the right candidate. We expect it will take real time to put together (our guesstimate is 4 full-time months, +/-1.5) We also expect we'll be working with you along the way to guide development and fill in blanks should it become necessary.

Interested? Please get in touch with me! dave[at]getcloak[dot]com

It's really tempting to slack off on the PhD when you get a big contract, but if you're serious about the PhD do not put it second. If you're in classes still, you should be good for a while, but once you get into research it will really depend on your advisor. e.g. I worked on research all-out 3 days a week and then had 2-3 full days each week to freelance while still maintaining a social life.

Also, depending on your stipend, be selective with clients. If they seem like jerks don't take on the added stress. It's one benefit of moonlighting when you don't NEED the money to pay the bills.

Technology has advanced well past the printing press, so Airbnb can actually do much better than that.

Technology problems and social problems go hand-in-hand. For an easy example, consider moderation. Online communities are improved (the /r/science subreddit), or torn apart (Twitter users) based on the strength or weaknesses of the available moderation tools.

So what, technologically, could Airbnb do to improve its user experience for marginalized?

It could use inclusiveness as a search signal. This style of tactic (forcing improvements through algorithmic penalties) works extremely well when Google uses it for search rankings. For instance, if users self-reported their race, and listing X systematically fails to rent to people of certain backgrounds, penalize it in the rankings. Make it well-known that this is a factor, but don't tell people when they are violating it.

Something less-likely to work is a report/moderate cycle, to manually review these types of cases. The problem here is that it's almost impossible to review intent; maybe I really DID think my vacation was going to be cancelled, but then a project at work got cancelled so it came back.
I suppose that depends on the definition of "cultural impact." L0pht talked to the US senate (and Mudge went on to join DARPA), CCC members consulted the german government, etc. Anonymous was on the front page of a whole lot of newspapers though.

--- edit ---

Doom is a good example: It both made it into popular culture (sold lots of copies, the Doom movie, etc.), but also hat cultural impact in the sense that it pushed 3D graphics. L0pht, the CCC, etc. had cultural impact in the same sense but never really made it into popular culture. Anonymous on the other hand did make it into popular culture but had no cultural impact (that I can think of right now).

Well, it really does if you don't take "richer" to mean "has more US dollars" (or whatever currency) and instead take it to mean "has a better quality of life."

Hmm. Nice work doing the math out. My statement was evidently erroneous. Which component makes the battery so expensive, then? Do you know? I am not really familiar with its make-up past the lithium.

One thing to consider, though, is that lithium coming from Chile is going to have a significant mark-up owing to transportation and tariff costs. Do your numbers take that into account, or were you looking at the raw material value?
I wonder if the same effect comes up for white names coded as working class, as well? I seem to recall that for employment stuff, names that coded for "poor redneck white" did pretty much as badly as "poor urban black" in (at least some) studies.
