1) The sonic booms are from this thing moving at only a few hundred feet overhead. Concorde was also designed with efficiency in mind: sonic booms lower efficiency. I doubt as SLAM was, since it doesn't "burn" fuel. The airframe isn't even area ruled. I doubt it would flatten a modern steel reinforced concrete building without falling on it, but it would certainly break windows and damage some structures.

2) Yes, it was relatively clean with no reactor damage when tested on a stand for 5 minutes. I suspect a few days or weeks of flying at tree level the reactor would physically decay. Breathing uranium/beryllium dust seems unpleasant to me.

3) It was definitely designed to fly at low level at Mach 3 for at least as long as it takes to drop all its bombs. What happens after that is kind of irrelevant, but whatever it is is guaranteed to make a mess. If you stop to think about it; this is inherently a high temperature device. Whatever they were using for electronics and servos would have had to deal with this. It would be interesting to know how some of these subsystems worked for certain.
Because they've proven to work, for a lot less money than the US spends on healthcare per capita.
This is one of several reasons I have written off moving back to the US. A unexpected bonus of being an expat is I have no Obamacare requirement. I don't have to buy US insurance (since I couldn't use it anyway) and I don't face an IRS penalty.
before I realized that it seems many tech-related blogs are from Medium nowadays, what's behind this is a mystery to me.
This is probably more related to the cost. Someone who can throw away USD 1500 (or similar, I believe it was that ballpark) on Glass is not only an asshole, they're a rich asshole, and therefore fair game. Never underestimate the way money can unsettle people irrationally.

> VR is going to fulfill the promise of teleconferencing.

This is perhaps the most important aspect of VR to me. Presence with people who aren't present will be VR's killer app. Time and time again we see that messaging is the biggest use of most platforms. Messaging in VR will just be turning your head and talking to someone.

I am really interested to see whether meatspace office buildings will be able to compete with shared virtual workspaces.

Turning your head or walking across the room to ask someone a question was always the key differentiator for physical offices. VR takes that away. Maybe there is some killer feature left for offices, but I kind of think this might be the moment where the disruptive technology (telecom) overtakes the incumbent (meatspace).
I'd multiply by 6 twice then divide by 10.

But it isn't the "move the decimal point" of other metric unit conversions.
NICUs were not very common until the mid-1970s so this component of care probably wasn't covered in Mr Friedman's study. Prior to that time premature babies with congenital issues typically just died.

And medical underwriting was a thing because people that have been sick before are bad bets. There's no need to imagine some kind of conspiracy here, it was just business.

But hey lets just make up some more numbers to fit the narrative.
Is Bi-Directional Replication in Postgres Transactional?
In a perfect world, sure. I once worked for a company that bought another company's assets (mainly the code base) and at some point in the past the code base had been migrated from CVS to Subversion and the commit history was simply lost. They probably just took a clean copy of the main branch and started a new repository. "Why was this written this way?" was not a question you could unearth from the repository, sadly.

(Another company I worked for had commit log entries like "I like cheese" so perhaps this company wanted to erase history for a reason. Here in the 21st century version control systems finally get the respect they deserve, though I bet there's a sad number of shops that still don't use one).
I'm shooting you an email. I'm in your area of the country, have worked for large defense primes in data security, and need some guidance.
> I call it tangled as it's mixing two flavors in one "view", whether you like it or not: JS and HTML.

Data (JS) and presentation (HTML) are necessarily coupled. Hiding that coupling in crazy tokens and syntax in HTML is not equivalent to removing it.
IMO the standout difference between Angular and React is how you think about your application. Do you like functional programming paradigms and want to apply them in writing your components? Use React. Do you think immutability is too restrictive and love things like two-way binding? Use Angular.

That being said, I'm a bit disappointed to see no mention of Aurelia although the author has mentioned other frameworks like Emberjs. I have been writing production code with Aurelia for about a month and this has been so far my best experience with any client side javascript framework. ES6 is very capable and Aurelia did it right by staying out of your way for most of the times by letting you write your components in plain ES6. All the while providing binding capability(with beautiful syntax), a very powerful router and out of the box package management support. I feel with all the commotion in framework space, more people will appreciate the simplicity of Aurelia and that camp will get bigger as time goes by.
>It means they fall back on thinking; or, more precisely, they think of themselves as being the kind of person who falls back on thinking rather than feeling.

Yes, and that tendency is mutable too.

> the box you slot yourself into circumscribes the habits you'll form, and then things that become habitual feel more "natural."

You mean they feel more comfortable, and sometimes that will be conflated with feeling "natural". Habits of the mind are just that: ruts and tracks that have deepened over time with repeated actions. They can be changed, like anything else in the phenomenal universe.

> Everyone on HN is pretty familiar with the introvert/extrovert distinction, and also how carefully it has to be explained lest it be confused with "outgoing" vs. "shy." The real distinction, as the 'common wisdom' goes, is about how you "recharge."

That might be the common wisdom, but that was not how Jung or even MBTI defines introversion and extroversion.

> I personally think it's clearer to phrase it in terms of the contrapositive: introversion/extroversion is about what you reject when you're out of willpower. Whatever comes more naturally to you—whatever's more habitual—will "cost" less to keep on with.

I've been talking with my meditation buddies about this on and off for the past year. Some of them are (or were) software engineers and some of them are not. Over the past year, I've been finding that idea of introversion and extroversion is BS, but I have not looked into it deeply enough to find any good insight.

It smells like BS to me because it seems like a truism that hasn't been thoroughly examined.

> And do note that most of the MBTI factors do occur separately in other personality-trait assessments, that were not created by mystics. :)

They appear in other personality-trait assessments because Jung and the mother-daughter team of Meyers and Briggs were credible enough scientists/speakers that people forgot where it came from. I didn't say Jung was a mystic. I said Jung had mystical experiences. He had been trained as a scientist, then out of the blue, he started having experiences for ten years. He went with it and started observing it, making theories about it, much like a cultural anthropologist would when they immerse themselves into a different culture. Where did you think Jung got his ideas of archetypes and collective unconscious from? He observed them directly and called them such. It's really funny to me how "mysticism" has become such a dirty word and used for name calling :-D
Amazon's product search is amazingly bad and the user reviews are getting faker over time. To me it's amazingly hard to shop on there. Feels like the engineering team is focused on their many other businesses and ignoring their retail stores.
I'm 30 years old and haven't been to a doctor in about 10 years outside of simple things that I paid out of my own pocket. Nothing that a year of healthcare would cover, and considerably lower than it'd cost.

I'd have paid in tens of thousands of dollars over the course of that time, and for what? What ifs?
Of your examples, I believe only dereferencing 0 is undefined behavior. The rest are, I believe, implementation defined. It is implementation defined behavior which allows C to be used across heterogenous systems. I talk about the difference elsewhere in this thread: https://news.ycombinator.com/item?id=10839389

> Having to write HTML using either JSX or the ReactDOM syntax was a complete nightmare.

Can you expand on this? I find writing JSX to be a breeze. JSX is basically HTML with a few small tweaks (e.g., for => htmlFor, class => className). If you use a linter, it will catch those mistakes for you while you're learning.
> Apparently some/much of this has to do with our state choosing to opt out of dealing with increased medicaid funding, so... yay... I guess they get to show obama how bad ACA is by... digging in their heels while we all just pay insanely increasing pricing?

Well, the increased Medicaid funding is temporary, but comes with permanently higher Medicaid spending. So a state might reasonably not want to accept that offer.
right, it's "care", and otherwise the sentiment is correct
1) When working with a new client I'll spelunk through the contact to understand the person better. What's their background? What technologies have they worked with before? Do we have anything in common I can use? How long have they been in this field?

After that, I'll circle out to their management and coworkers. What does their org look like? Is my contact the decision maker or just a junior person who will shoot everything back and forth to their boss? How many bosses are there?

A little homework goes a long way, and LinkedIn is a very easy way to start.

2) I load my own profile with buzzwords and technologies that I know the competition is using. Recruiters happily latch on to that and send me job listings, 90% of the time I can decipher who is actually hiring. Recruiters lazily cut/paste stuff and Google is your friend. Now I know a little more about the state of my industry and who is struggling to get stuff out the door (gee, why do they need 4 manufacturing engineers all of a sudden?)

Sometimes you see the same company trying to fill the same headcount for a year or more. Multiple recruiters, same job listing. You make a mental note that they are either a disaster to work for, their pay/benefits suck, or there is a culture problem. Next time you network, you can dig deeper and learn more (hey, what's the story over at FooCorp? Why can't they find an Android dev?)
Honestly I wouldn't hire a web designer that can't code a little Javascript. It's been a while since knowing only HTML as a web designer has been acceptable.

To answer your question though: they're probably about the same level of difficulty, and I don't think it's a great argument for vanilla/React/Angular because a person who doesn't understand code trying to modify stuff that is controlled by code is going to break something regardless of what JS framework you're using.

I prefer JSX because it's not pulling wool over your eyes - you're building a JS app, not an HTML app - so let's stop pretending. The ESX syntax is just a nice way of forming a hierarchy of class instances. The beauty of React is that you could come up with your own syntax for doing that and use it just the same, because React is just Javascript.
The missing process-- the engine Jacobs finds for all economic life-- is import replacement.

What does it mean for the US, when we can't keep up with our demand to import qualified employees?

EDIT: "A city region is used to change, is constantly innovating; a supply region is not. It treats its resources as God's gift, a presumably eternal windfall; it prepares only half-heartedly for the end of the boom, and when it comes it's caught short."

Substitute "city region" and "supply region" for something and "worker" and maybe we have something that relates to another article about how workers rent their resources for pay. (Which I can't find right now.) In other words, is being a conventional worker like being a "supply region?"

Perhaps people are the opposite of cities? When people start to prosper, they seem to be outsourcing tasks.
Actually, that LinkedIn facial recognition app sounds awesome. I have trouble putting names to faces at large events like tech conferences, and it would be great to have a subtle 'This is Bob, the CTO of WhateverCorp, you have a meeting with him next week about the Random project' show up when I scan a room. Isn't facial recognition and then looking up the relevant background details the go-to application for most 'futuristic' imaginings of wearable tech?
SmartOS is a good choice. They provide KVM and joyent opensource their SmartDataCenter https://github.com/joyent/sdc

so you can provision VM with API.

They are developing for LXC which will give you better performance in the future.
My qualm with Medium isn't the idea of a hosted service, or the bloat, or even the annoying preciousness you allude to, but the degree of reader surveillance baked into the site. It pings back your exact scroll position in the document very frequently, and the behavior is neither advertised or (last time I checked) something you can disable.

I'm kind of surprised you're a Medium advisor given that you are not the biggest fan of surveillance culture yourself.

I have seen that as well, and believe it to be genuine/OK. I take it to mean that the warehouse nearest you has it in stock and if you add to your cart and order it, you'll get it by that promised deadline.

If a few hours pass and in the meantime that warehouse sells out, you might be past the cutoff for the next warehouse that has it in stock.

(Not an Amazon employee, just an extremely frequent customer...)

Except for the USPS last-mile shipments, I've rarely (< 5%) had Amazon miss a guaranteed delivery date. On USPS last-mile shipments, they only seem to make about 2 in 3 on-time, which means I get a free month of Prime everytime they miss. I'm almost to the point of trying to figure out the pattern that gets last mile USPS to pickup free months instead of doing the "no rush" which only nets me $1 or $2 towards e-books and video rentals.

Are you sure? I think you're misremembering.
Idea averaging is a wonderful thing, and you should probably do it way more than you already do, and it should probably be your default mode when looking to choose between ideas.

A lot of this is spelled out in the literature about why ensemble methods tend to be superior to individual methods in statistical inference, which has a lot of ties to why averages of non-expert opinions tend to be as accurate or even more accurate than small pools of expert opinions.

In the limit, when you reallocate credibility to a set of ideas in a manner that is fully derived from your prior beliefs and the evidence you have, it becomes exactly Bayesian reasoning. A posterior distribution is exactly an "idea average" where each idea (each potential outcome) gets as much (and no more) credibility as it deserves, according to the prior and the probability model at hand.

Here's somewhat of a popular account of it:

< https://www.washingtonpost.com/business/is-it-better-to-trus... >

There is also the recent stuff under the marketing buzzword "Wisdom of Crowds" e.g. < http://onlinelibrary.wiley.com/doi/10.1111/j.1551-6709.2011.... > or the Wikipedia article on it too (and many sources that point out potential problems and corner cases that are also important).

In general though, I think I have to disagree with the article's premise. Unless two distinct ideas truly are mutually exclusive (most things aren't), then it's better to have a diversified portfolio over the space of all the ideas than to put all your eggs in one basket, and averaging ideas is sort of a humble heuristic that seems to work in a lot of areas.
Living in a consensual massively-multiplayer VR space, on the other hand, the rules of the space can be changed to suit its citizens: morality can be fully enforced

Are there any massively-multiplayer online spaces which are completely without griefers, trolls, or immorality of any sort? Which ones? (And try not to arrive at a non-empty set by redefining all complaints conveniently as "whining.")
When I am in such environments what I always to is to add some little cleanup to features that I am adding. In a code review, it is always easy to justify that I am also removing these 5 lines that surround the code and are not needed anymore. It takes time, but it helps.
This is the epitome of an industry where people with good ideas could benefit from being paired with insider advisors.
I'm genuinely curious about this, particularly the "easy to see a doctor" part, because I know that quite a few Canadians travel to Thailand for non-emergency medical care mostly due to long wait times. That's according to a few statistics published by some of the private hospitals in Thailand. I've seen few outbound studies published by Canadian researchers, although here's one from last year [1]. From what I understand, out-of-pocket costs aren't that much difference between Thailand and Canada.

I made some pretty unreasonable but convenient assumptions with the basic compound interest formula in back-of-the-envelope math to arrive at ~2.25% annual interest rate.

http://www.wolframalpha.com/input/?i=compound+interest&a=*C....

Assumptions:

- I know the amount was not dispersed all at once at the start

- I have no idea what compounding frequency seems appropriate

- Does not account for inflation

- Time frame: 12/29/2008–10/17/2014 per the linked pdf [1]

Aside: $17.2B 2008 dollars adjusted for inflation becomes $18.89B 2014 dollars.

No surprise there. This year I did almost all of my shopping on Amazon and it worked out excellently, especially considering that I was having Christmas in another location and just got everything delivered straight there.

Our family also discovered something great this year: Wishlists. By creating and sharing Wishlists we were all able to get a much better picture of the specific items and areas of gifts that each family member was interested in. It results in much more lucid shopping than blind guesses and/or plain text communication.
Ah, I missed that bit.

I guess the difference is in the cost of healthcare then. Also we don't have health insurance via employers.

Writing this from a mid-2009 13" MacBook Pro (2.26 Ghz processor). I've also upgraded RAM/HD over the years, as well as replacing the battery. It's mostly for internet with some occasional programming and sound editing. It runs the latest Mac OS.

Amazon feels like more of a crapshoot all the time. Just bought a pricey Thunderbolt dock. Didn't see anything I plugged into it, despite being new. Went to MicroCenter, paid $50 more for same one, worked great. (even tried new cable on Amazon unit, just in case that was the problem)

My point isn't a story about a particular product, but to say that I'm not as surprised as I once was. During the holidays I had two boxes of food etc delivered (one Prime Pantry, one regular purchase) that were busted open or otherwise required my cleanup.

Amazon is truly becoming the online Walmart: cheap, compelling, but you expect the worst.

Citizen Frondo, you don't understand. If the market says you must not be insured it is right because the market is always right. Why, on this board you had people tell with a straight face that one should not bother to eradicate schistosomiasis and malaria in the African continent because if the continent was meant to be productive people would be spending money in the project right now.
I don't agree with your statement about the New Zealand healthcare system. For instance, in regards to dialysis:

For patients using a haemodialysis machine at home, the health service provides the dialysis machine and all the medical supplies patients need, so the treatment itself is free. The same applies to patients on peritoneal dialysis.

Patients do have to pay for things like some medications and home haemodialysis patients usually also pay for the extra power and water needed to run the machine and to keep them warm during dialysis. Some District Health Boards contribute some money to the cost of power and water.

For comparison, my state's ACA plan is the same as Medicaid (several choices of insurance providers and I believe no cost for prescriptions).

The more surprising part was our Republican Governor was the one that advocated for it and pushed it through the party line (with a lot of grumbling). His argument was it would save the state quite a bit of money and so far I believe it has.

I'm not talking about cars as status symbols, but as factors of identity. Teenagers want cars because it is a rite of passage. Half my coworkers want trucks because they are 'outdoors' people. And some do use it as a monetary status symbol. Some people are just car people who have strong opinions about the car they drive because it is part of their self-expression. This is a pretty big thing in American culture.
