This critique completely misses the boat. The author explains why HealthKit will likely never share data from an EHR via some sort of HIE. She's right, and that's not the point. Doctors (usually) do not trust health data collected by a patient, patients however are interested in collecting data for themselves. Look at this through the eyes of someone with a chronic disease like T1D or cancer. The more studious among us collect reams of data for our own comfort and understanding, occasionally it is useful to a doctor.

When my daughter had cancer, the doctors didn't come to me for the results of her last CBC, they looked in their own computer. No doctor would have trusted my interpretation or recollection a CBC anyway. My wife and I did track those numbers very closely, and we did so that we could make day to day quality of life choices for our daughter. These choices usually did not involve a doctor.

Oddly enough there was a kind of data that originated from us that the doctors did rely upon. When you're dealing with a disease that has a 30% (or less) survival rate it's unsettling how often you hear a doctor say "we've never seen that happen before", especially when you are hearing it from the top doc in the country for that disease. During our multi-month hospital stays my wife and I traded off in shifts collecting information at 15 minute intervals of everything that went on with our daughter in the hospital room. Often times the situation was very dynamic and the nurse was obviously not standing at the bed side 24/7, and the doctors usually did rounds only once a day. Additionally the nurse's acute care flow sheet only tracks a handful of very specific data points. What we discovered was that while the doctors took oral anecdotes with a grain of salt, when they saw I had written notes they got into the habit of simply asking for my notes and then wrote down what they needed and then our discussion of her state began from there.

I apologize for the messy stream of consciousness here. While I'm not a health care professional I've invested a considerable amount of time learning the inside of hospitals, and I've also built a handful of software products for the healthcare industry including a proprietary HIE. If I learned anything from those experiences it's that there is data the doctors want, and there is data the patients want, and they don't always overlap and they don't always trust each other. If there's going to be a revolution in patients taking ownership for their health information, care plan, etc... it's going to start with the patients collecting the data for themselves through various devices and manual means and it will not be the results of scans, labs (or imagine this... HIV test results) being streamed to the patient's phone from the hospitals EHR.
Here in the Yukon we get a solid month where it's -40C/F and a few months of -25C to -35C. It snows a lot, then the snow turns to hard-pack ice.

I ride every day. You can too.
> When I was young my dad used to bike me to daycare/school all the time.

How did all your siblings fit? Or did your Dad make multiple trips?

> live within a 15-20 mile radius of work

You really think people want to bike 20 miles? That's going to cost you about 2,000 calories (round trip). That's completely unrealistic for most people. They would have to double their food, plus end up exhausted every day at work.

And that's for perfectly flat terrain!

(The weirdest part is the extra food costs more than the equivalent gasoline, and produces more CO2.)
Great job! :)
We fixed it.
Maybe it's the sounds generated by the app, but I like to think that my furious clicking causes some of the lightning bolts.
I'd like to hear that argument too. Also, there are a lot of people who prefer cycling over even decent public transit. Doesn't apply in SF, but does in NY/Brooklyn.

People are leaving the dense NE cities and going to the less dense south and west ones.

To pick the largest city in the US, the population density of Manhattan went from 21 in 1910 to 12 today. And Lower East Side went from 70 to 16.[1]

Also look at construction statistics, new home construction outpaces population growth, people are moving into less dense areas and need new housing.

They build a bit less than 1 million homes every year, and most of those are single family homes.[2] Population growth is about 2.8 million each year, but that's people not families.

Letting folks download some source code won't help; that's not where the value is.

Did you read the article? It's less about open source code than it is open source intelligence.
hey, thanks :)
This is absolutely not common. What country are you in?
I don't have to rebuild every major piece of transport infrastructure to support electric cars.

Social issues refer to body odor my bike riding colleagues carry around with them all day because our workplace doesn't have a shower.
The first hurdle is that Erlang works on modules by default. Those are expected to be compiled from a file. Now Elixir fixed that problem. For Erlang, it is probably doable via a compile-reload cycle hack. I guess it just hasn't been a priority. Maybe it should be...
Ah yes, how sad that it is harder than ever to abuse communication networks to sow distrust and anger. Thanks to better filters and a movement toward identifying users, most of us are less bothered by bad actors than we've ever been.

What surprises me most is the author's lack of contrition. I forgive people for past mistakes, but she still fondly remembers how she made others' lives hell. Fortunately, the Internet also remembers. People who google "Kate Levin" will probably find this article. If they're like me, they'll be a little less likely to associate with her.
Really? Do you actually think that Jaynes is being unreasonable when he assigns ESP a prior that is lower than "has some sort of trick" or some other thing that generally turns out to be the explanatory factor for a magician?

He's saying that ESP is an unlikely explanation. He's saying that it is Probably Something Else. The experimental data cannot distinguish them. That's why it's not compelling. It has very little to do with rationalization. It's a terrible test.
Disclosure here - I'm a racer, own some 10 odd bikes for various disciplines, but realize my 4 mile commute to the loop every day does nothing to further that. It's essentially the "garbage miles" your typical racer talks about. As a result, I typically ride at a pace into work that is focused on not sweating as much as possible, but there are 4 months out of the year that it's so cold out that I've got to put on enough clothes that unless I get it JUST right (almost impossible in chicago) I have to err on the side of being too hot, and 2-3 other months where no matter if I'm wearing my fancy near-mesh high tech Assos jersey or not, barely going at a pace to beat walking, I'm going to be soaking wet from the heat.

As far as "Separated" I guess it becomes important to define separated. If there were physical curbs between, I could see it - but where I have seen that those tend to become even more pedestrian travelled, but even the flexible post at interval type ones, I've seen most of those destroyed in the first year they'd been put in by plows, UPS drivers, you name it. It's a bit of a tall ask to put in full on curbs, as much as I think it could work. Most of our major downtown streets aren't much wider than SF's smaller streets, with parking on both sides.
The right turn lane is removed. Now, instead of having straight traffic moving through while right turn traffic shifts to the right out of the way, that traffic will have to slow behind the right turning cars. The added set-back of the cross walk helps, since one car can wait for e.g pedestrian traffic completely out of the flow of through traffic, but there is little doubt the traffic will flow more slowly.

As somebody elsewhere said, if you get more people riding, you are removing their cars from the road, but there is a real chicken and egg problem, as drivers will be very upset if they see their commute lengthen.
How would this lazy-vector-mapping compare to the optimizations used in std::valarray? Or are those optimizations just the ones you mention here?
In the first link he mentions that if we read one thing in our lives it should be "philosophy and the social problem." (It is on my todo list, I haven't actually read it.)

Sometimes the sweating just can't be avoided. The last few blocks of my ride ascend ~150 ft. It's steep and on any morning that's above 55 I'm breaking a sweat. And riding slower only drags out the effort for longer.
Not surprisingly, being London, the weather was lousy.

650 sq ft is a pretty large place by Korean standards. I expect by Tokyo or Singapore as well.
Since we're throwing around anecdata, I once had a summer commute from Back Bay -> Lexington. It was 1:45 by T/bus, 45 minutes by car, and an hour by bike. I was in school at the time so I was hesitant to bring my car to the city, but it would have been the obvious choice if biking hadn't been so damned convenient.
Japan might be a partial counter-example to that.... There's traditionally been almost no dedicated bike routes or even lanes in Japan, although this has (very slowly) been improving a little in recent years and there's fairly extensive bike parking infrastructure in many places. Despite this, bike usage is very high in many parts of Japan, with numbers dwarfing anyplace in the U.S. (~20% mode share in some places).

However, the situations aren't entirely comparable, as typical bike usage in Japan is fairly local (to local shops or between home and the station), with public transport being used for longer trips (thus the emphasis on bike parking around stations and other major destinations). Japanese urban layout, which clusters housing and commerce around the nodes of an extremely large and dense public transport network, tends to encourage such usage.

Americans, as I understand it are more likely to view bicycling as an alternative to public transport rather than as an adjunct to it, and thus want faster speeds and more extensive bike routes.
I very much like the way he lays out the groundwork. It answers fairly directly a lot of criticisms I've seen leveled at probability.
Steele left the CIA quite some time ago, after his advocacy for open source intelligence gathering failed to gain any traction. He's specifically criticizing their methodology: "I'm a spy who's telling you that spying doesn't work."
Yeah sure. Australia struck me as very "american" in feeling. Lots of the new Chinese development is specially car friendly. Same with new Russian development. I was surprised with how unfriendly Ireland was to anything but a car.
Been living in San Francisco for a few weeks now and it still takes me a minute to figure out which direction I need to take in the Metro. Why they chose such unintuitive names such as Inbound and Outbound baffles me.
Seriously. I'd be very interested in offering him a job.
People aren't using Go because of Google, but Go gained a lot of attention, and therefore a lot of people looked at Go, because of Google. Google also did a good job with developer outreach, which, IMO, is what keeps Erlang from moving to the next level,
Ouch, why on earth...

Anyway, good blog post.
I'm surprised a 10 minute drive translates to a potentially 1:20 minute ride. I feel like one of these numbers is exaggerated.

Regardless, if it's not right for you it is right for someone on your approximate route. So if you can't be convinced to ride in but they can that's win-win. They have an easier ride into work on a bike and you have a less congested drive in because the biker is one less driver.
Do you think the evidence in favor of violent movies causing violence is significantly stronger? Comparing to the climate science debate implies that you think there is a huge disparity in evidence. If so, it should be easy to present some.

Personally, I'd think it would be hard to directly test the proposition "existence of violent movies at all increases baseline level of violence in society". You can't do a randomized controlled trial, and there are no good natural experiments. Trying to measure both variables across a range of communities would be hopelessly polluted by confounders. Therefore, I'd spect neither side to have a very strong case, which is exactly the point of the article.
I know few people who are working for company more than 5 years and are underpaid. But when I asked them, they were more concerned about seniority not about paycheques.
"Without bikes, I'd just walk and metro."

Exactly my point. You wouldn't buy a car. People who live in Boston/Cambridge only use their car to get out of the city, not travel within it. For people outside of the city coming in, bikes are not a replacement (trains and buses are).

Now if the plan is to have fewer people coming into the city, then bike lanes are great for discouraging that, but I'm going to guess that is not what the cities want. For example, I have a new startup and since we mostly live outside of the city proper and are tired of commuting in (especially to the nightmare of Kendall Square), we're setting up shop in the suburbs where there is unfortunately no public transportation.
But in a language with mutating side effects, and iterators, I'm not sure what this buys you over:

for (auto& num = file.line_iterator(); num != file.end(); num++) {
if (atoi(num) == 42)
return true;
return false;

Note that 'line_iterator()' isn't something that (as far as I know) is defined in the C++ standard library, but there's nothing preventing it.
Interesting points for sure. At some point I just say that sweating after a commute is something we have to deal with (same as getting fat by driving a car :-)). I'd rather bike and be sweaty than fat and driving a car (yes, I know not all car commuters are fat, but in generalities...).

The separated thing is super interesting to me. Obviously we couldn't do it on all streets, like the very skinny SF ones you talk about (I live near many of them in the Lower Haight). On those, which are not major thoroughfares, mixing bikes and cars is fine. But when it comes to a 4-6 lane street like Market St (or some in Chicago), separated makes sense. The traffic will go around if the street is less amenable to them. It's the same argument as taking down a freeway through a city. SF did it both at the Embarcardero (well, that one was by natural causes aka an earthquake), but then also at Octavia. Traffic slowed, neighborhoods revitalized. Studies have been done showing that taking these down doesn't greatly increase driving times, and often the traffic driving them doesn't actually stop in the city that they pass through. Instead they pollute the air and leave. Strong argument for taking them down, IMO.

But I've digressed. I agree there are challenges and never a one-size-fits-all solution. But there are solutions that are not currently being put into place that benefit the vast majority.

Six months of near perfect bike riding temperature with moderate precipitation and unusually warm winters that far north.

In fact, the record high ever for the city isn't even within 10 degrees of the temperature I've had where I live over the past two weeks. Our all time average, not average high, is about the same as Copenhagen's record high.

Our winters are colder and wetter also.
It was grey and lousy when I was there too :-) Still a lot of cyclists including my old coworkers.

I'd dare say we could fit 4 bikes in a much smaller place too. It's not the size of the place that's at debate here though.

Just FIY, "Open Source" in spy-speak is not typically talking about software.

https://en.wikipedia.org/wiki/Open-source_intelligence

In other words the title is not about open source software revolutionizing intelligence agencies. It is about something else.
That chapter was very interesting... until I got to this:

"Scientists can reach agreement quickly because we trust our experimental colleagues to have high standards of intellectual honesty and sharp perception to detect possible sources of error. And this belief is justiﬁed because, after all, hundreds of new experiments are reported every month,
but only about once in a decade is an experiment reported that turns out later to have been wrong."

Er.. what?

Yes, but at the same time "If you can't explain yourself in a single email, consider calling, texting or meeting in person instead." - so you do exactly to your co-workers what they do to you - in an effort to make yourself more efficient?
It's not fair to speak about Elixir & Erlang as a single piece of tech any more than it is to speak about Scala & Java that way. Elixir targets BEAM, but that doesn't mean it's anywhere near as mature as Erlang.

Elixir is on v0.14 or something. Far sub-1.0. It's a really beautiful language, but it's not surprising to me it doesn't have a Rails/Django analog when they're still introducing backward incompatible changes to the core language.

Also I really have no interest in learning a language just to write yet another website in.
> Why use regex? It's much simpler to write a URL validator by hand...

I actually have a use-case. I am firming up a feature right now that detects when a user types a url into a text field and replaces it on the fly with a footnote-style reference number (much like your comment above). This is done to (1) minimize input string length, (2) draw the benefits of a consistent interface, and (3) avoid screwing around with the fragility of url shortening nonsense.

I may regret this, but here's a link to my dev environment for this feature (please be gentle), to see it in action:

https://cloudcity.tenfourgood.com/cloudcity

...just start typing in the big text box and add in some urls.

It uses a fairly ugly-looking regular expression[0].

If you take out the unicode mumbojumbo, it's not really THAT tricky of a pattern. It does fail on IP addresses and it may be a little over-aggressive on matching, but, I wanted it to catch things like "abc.com" and "//xyz.com".

Edit: Formatting and clarity. Removed the explicit regular expression because it predictably got garbled.

Do the math, how far can you get in a car doing 60 mph in 10 minutes? How far on a bike doing 10mph? Toss in a couple hills.

If there are any people riding bikes on my route I have yet to see them in 7 years.
The layout of American cities is probably not the result of market effects.

As the author of a public transit iOS/Android app, these kinds of improvements to Google Maps both excite me (from a "that's cool" perspective) and worry me (from a business perspective) at the same time.

Real-time data is an area Google haven't pushed too hard into at this time (despite developing the GTFS-RealTime standard), so that has been an easy way for me to differentiate from Google Maps.

If anybody's interested in the kinds of real-time and static data Google (and other developers) use, I collect and archive many of the feeds here:

http://transitfeeds.com

Hoping to add additional tools for browsing / searching this data when I figure out how to make it all scale nicely.
That's fair, but that also doesn't necessarily mean that people are moving out of urban areas. Also, if you haven't noticed, NYC is still VERY dense (I used to live there). You could also make the argument that the mean center of the US has moved because there are a lot more people in the US now than there were in 1910 (I dont think anyone would argue against that) and more people have moved West as cars have become more prevalent and air travel is much easier. Therefore I don't think your argument stands.

I'll also present you with this about apartment construction now driving the economic recovery, not single family homes (disclosure: I work for rentals site hotpads.com, owned by Zillow) - http://time.com/102822/housing-apartments/

Actually it is largely about that and applying the same principles to other areas of society, such as finance. The subject of the article, Robert David Steele, calls this Open Source Everything and draws attention to the strength these disparate applications derive from cooperation: The open source ecology is made up of a wide range of opens – open farm technology, open source software, open hardware, open networks, open money, open small business technology, open patents – to name just a few. The key point is that they must all develop together, otherwise the existing system will isolate them into ineffectiveness.
Not to detract from this service, but for anyone who's looking for a good push app, I can highly recommend the World Cup app from ITnext. As a heads up, the push messages for goals arrive before they actually happen on TV, due to broadcast delays, which can be an annoying spoiler.

That doesn't have to be true. The NY examples can hold true, and the center of mass for population can move west, while overall population density still climbs. For example, the east coast cities could change in no way, while midwesterners moved to more dense western and southern cities (even if they are less dense than the East coast, it's still an improvment). This would result in the population shift you identified, while still restulting in an increased overall population density.

WRT NY's density falling, it could be an outlier or the norm. Still, from what I understand overall population densities are increaing in the US. [1]

edit: Clarification and spelling.
As a programmer who develops software for public transit, there is a lot of opportunity for technology to make a difference. But, it's not the kind of market that VCs and entrepreneurs prefer.

Public transit agencies vary dramatically from city to city, but they are the ones who provide Google with data on their transit system's timetables. In fact, Google is the last in a chain of software and manual labor that creates and manages transit schedules. It's very hard to create software that captures all the nuances and variations in transit to create a one-size-fits-all solution.

The other tough part is funding - public transit improvements are often driven by grant money because the operating budget all goes to day-to-day expenses. And oftentimes the wealthier people who could make a difference in transit (e.g. SV techies) own cars or otherwise avoid public transit because it's so inconvenient, so they often don't notice the problems.
They show the detectors that picked up the strikes. I don't know if a single detector can determine distance, or if the strike location is triangulated using angles from multiple detectors.

[edit] Oh, the detectors are quite simple. They use GPS for position and time and report time-of-arrival of the elctromagnetic pulses. The server then uses that information to figure out where the strikes occurred.
