Australia does not have huge deposits of hydrogen they're just sitting around trying to find uses for. So the input for this technology is imaginary.

Making ammonia out of hydrogen, which is so useful that half your food comes from it, is called the Haber-Bosch process (https://en.wikipedia.org/wiki/Haber_process), and has been around for about a century.

Ammonia is a pretty crappy way to move things around too. Not as bad as hydrogen, but if you have ammonia, reacting it with some CO2 to make urea is how the professionals do it. Ammonia is still a dangerous gas or liquid. Urea is inoffensive little white pellets. You can already buy urea at American truck stops as "DEF" or diesel exhaust fluid.

Finally, unless they've miniaturized their technology to where you can pump ammonia into your car to run it on hydrogen instead of filling it directly with hydrogen, you're still limited by hydrogen's crappy storage density where it's needed most- in the car.

So let's take two flows and compare them to this technology's flows:

NG -> pipeline -> CNG -> CNG Engine (simple, if not all that widespread)

e- -> grid -> EV charger -> battery -> EV motor (same)

vs.

Aussie coal -> CO2 + H2 -> NH3 -> H2 -> H2 tank -> Fuel Cell -> EV motor

or

Aussie PV -> H2 -> NH3 -> H2 -> H2 tank -> Fuel Cell -> EV motor

I wish I could educate newspeople on how to distinguish real breakthroughs from university-sponsored snake oil like this.
Just to add my two cents (I work for Mozilla on Common Voice): without help from linguists, Common Voice would have made some very different and very bad decisions about all sorts of things like: accents, dialect segmentation, corpus curation, licensing, and many other things. Linguistics were absolutely instrumental. We tried to thank some of them at the end of our blog post:

Chalk it up to Uber and their ilk, which not only discourages people from using public transport, but also significantly adds trips, which wouldn't have happened otherwise.
A modern high res camera does allow for more mistakes though. A good photographer doesn't under- or overexpose 2 stops. I do. A good photographer doesn't so often realize that the good bit of the image is actually 1/5th of it, in the corner. I do.

So I crop 1/5 of the image and boost the exposure 2stops. If I do that with a camera just a few years old, the result is terrible.

Now obviously, if the image is bad or completely uninteresting to begin with then no technological thing is going to help. But it's nice crutches for beginners. After I cropped my image to 1/5, I learned what I should have done. In the past, that was a really expensive lesson (the photo was ruined). Now I get the lesson AND the photo.
The NYPD is fairly useless when it comes to traffic enforcement other than ticketing cyclists.

They'll ignore trucks blocking crosswalks (and endangering pedestrians). Double parking in bus and bike lanes. Tractor-trailers (which are technically illegal to drive through the city at all without a special permit for each delivery, but that's never enforced) blocking both crosswalks and the entire intersection because they didn't wait for the street ahead to have room, and making blind turns where they come within inches of mowing down pedestrians crossing with the light (whom they couldn't see because their cab and hood are too high, which is part of why they're illegal).

Heck, police cruisers are some of the worst offenders when it comes to blocking crosswalks; parking on sidewalks (thus forcing pedestrians into the street), and other such obnoxious behavior.

And when a driver crushes or kills a pedestrian or cyclist, the NYPD goes out of their way to defend instead of prosecuting the driver. Even when eyewitness accounts and video evidence show the driver at fault. Even when the driver was driving without a license or under the influence.
>How does military might factor in?

I don't think that sentence is grammatically correct.

The study does a poor job of explaining why there are so many roads in Turkey and most of the middle east, and yet such little development there. Such a stark contrast between western Europe and the Islamic world casts doubt on the idea that the roads played the dominant economic factor over the past two millennia.
> What is it with this obsession that every requires the best doctor?

Being only willing to settle for the absolute best doctor in the world is ridiculous, but it is perfectly rational to want to choose the best one out of a small group of candidates. I can't imagine approaching it any other way when my personal health is on the line.
So it can’t even be packaged cleanly and properly into rpm’s or dpkg’s?

China Hacking Underground Shows Rising Prowess

Did anyone here take a look at the source? Anything we should be worried about?
It's worth noting that Baidu having a global presence allows the Chinese government to use it to attack their cyber enemies, so China has a vested interest in growing Baidu. Last time, China used the Great Firewall to weaponize Baidu's analytics worldwide for the largest DDoS in history against github in 2015 because github hosted two projects that allowed Chinese citizens to get around the Great Firewall and read the New York Times uncensored.
I think that’s a false question. The point is that it’s actually not easy, not even in Nim (in fact, especially not in Nim).

Writing safe and effective Python is easy. So then where do you go from there for the ~10% of the codebase where a user could conceivably ever care at all about performance enhancements? Wholesale switching to a different language is quite a drastic (premature) decision in such case, whereas Cython gives you the same (actually even better) facilities for type safety and detailed performance optimization, and offers it crucially on a case by case basis.

I see a lot of cheering for Nim on this front. It makes me happy that some people enjoy Nim and like to use it. Cool! But it makes me sad to see the significantly wrong-headed discussions about it as a practical alternative to Python + Cython. It’s the opposite: choosing Nim is a wildly impractical way to get what Python + Cython does better.
For something like a desalination plant, I wonder if that would be a good candidate for pumping water up a hill/tower/something, and then using the stored energy the other 21 hours per day.
That seems like some twisted logic.

"I was just dumping data in logs, I don't have to care about privacy concerns. Oh, and now I have all this data on my server, since it's already here I surely deserve to process it without caring about privacy concerns!"

It should be noted that Facebook is pushing very hard for more meaningful interactions in the form of Groups. These groups are taking an increasingly large amount of the newsfeed. Facebook's stated goal with these groups is to create meaningful communities. I think, at least to some extent, they are succeeding with this goal.

Anecdotally, I know several people who say groups are the only thing keeping them on the network.

Interestingly, the groups also dovetail well into the continued growth of their ad platform; they tend to be interest based, so they help with ad targeting.
Some companies have already dropped future support of the mac version of their software based on Apple making it official that OpenGL is truly dead.

https://apple.slashdot.org/story/18/07/29/1939212/autodesk-d...

"According to a note posted on Autodesk's support website, while older Alias versions can run on High Sierra or earlier, "no versions of VRED will run on that operating system due to the OpenGL deprecation."

While openGL is not going to stop working on Mojave, it has served as a good excuse for autodesk to stop bothering with the work of developing mac versions and refusing to provide any support or patching of any future issue that might arise on current releases being run on mojave.

Apple is working very hard at killing the mac both because of what they've done to the hardware and what they're doing to their OS for any user that's not some grandma that does nothing outside browsing facebook on a $1500 macbook..

Alternate hypothesis: locations 2000-year-old cities predicts modern day prosperity.

And also locations of 2000-year-old cities predicts locations of 2000-year old roads -- uncontroversial I think.

The proposed mechanisms are (1) cities are stable on millenial timescales, continuing to develop and attract wealth
(2) geography is stable on millenial timescales, so the places where wealth-attracting cities tend to be located are the same then as now.

Contra (2), there has been a shift in importance of different transportation networks and energy sources. The roads discussed in the article are transportation network, but waterways historically have been even more important. And more recently rail networks as well. The shift from water to coal to grid-distributed electricity has loosened the connection of energy to geography.
The same authors did publish code for another recent paper [1]. So it doesn't look like they are adverse to publishing their code in general.

I'm not sure how you can say this when Meetup has been around for years. It does exactly what you describe.
Totally, but it's increasingly hard to find the older ones, and they wear out eventually.
Academically I knew what I wanted to do when I finished high school. I wanted to be a software engineer, and I became one.

It sound super fucking corny, but when I left home at 18, I didn't really know who I was as a person. University really helped me find that.

It's not just the independence, but the fact that at university you have a lot of free time, and you have a lot of opportunities to meet and interact with people from different backgrounds, who have different interests to you. I don't want to spend my days hanging out with a bunch of software engineers. I'm actually proud of the fact that in my circle of friends, I don't know anyone who's a software engineer. I actually hate talking about software or computers outside of work, I spend 40+ hours a week doing that shit, I want to do anything that doesn't involve software engineering for the other 128 hours of the week.
Bingo. I've been discussiing this on G+. In paarticular, adding topographic maps helps show transport logic pointedly ignored by the paper.

The areas may simply be more amenable to prosperity: good land, water, resources.

Roads were little used for transport. Goods moved by water. Rivers. Sea. Canals, mostly after 1500. Costs were 1/20th or less of overland drayage.

Transport routes are established between points of interest, and those develop according to potential. Several of the major roads follow coastlines or rivers. Others bridge river valleys, generally through other valleys and over passes.

The Roman empire itself grew into areas offering food, lumber, or other trade.

The paper's conclusion of causality is grossly premature and overstated.

IIRC, it's roughly 14 billion years or so. Earth has been around for I think 4 billion. Humans for around 10,000-ish. That number may be off, but it's well under 100,000. We, as a species, have gone from crudely drawn shapes on caves to starting to explore beyond the bounds of our planet.

The claim is that our journey into the stars is inevitable. That we will begin to colonize other planets. And that this colonization is exponential. To illustrate let's say tomorrow we know how to do it. The only issue is the time it takes. Let's pretend we can do it in 10 years. From nothing to fully functional, autonomous human colony in 10 years. Technologically equivalent. Which means that colony is also capable of sending out colonies. So now instead of one planet sending out colonies, you have two. Then four, then eight, and so on. Basically, every 10 years, you would double the number of planets inhabited by a species. In just 100 years, there would be 1024 planets supporting human life. In 1000 years? 100 cycles of colonization? 1.2e+30. Huge. There are "only" 40 billion planets that seem habitable in our galaxy. We'd have run out of planets to colonize at the 36th cycle. And even if it takes 100 years to colonize a planet to the point where they're just as capable, you're just really shifting the decimal one point. That's 3600 years to a fully inhabited galaxy. Cosmically, a blip in time.

So, the Fermi paradox says that given that colonization of other worlds is inevitable for an intelligent species, if life and human-style intelligence aren't unique, why haven't we seen evidence of other civilizations yet?

You answered your own question. Renewables cost more. Perhaps not if you factor in externalities, but those aren't factored in.
how do you regulate the membrane? does it degrade?
> Then simply use the older icons :-)

Simple for you doesn't mean simple for other people.

Without writing down the steps on exactly how-to use the older icons, it doesn't equate to simple in my opinion.

IOW, you probably had done yourself a favor to not use the word "simply".
To me it seems just as farcical to levy a $100 fine on someone who only has $100. What exactly does that accomplish?
No, it doesn’t. The police around here generally ignore traffic violations unless they are specifically conducting a “sting”.

I recently was told that this is actually a matter of policy, because someone discovered that cops were using traffic violations as an excuse to disproportionally target minorities, like the old “broken windows”
policing days.

Honestly, it even makes a bit of sense... traffic is so dense now and violations so frequent that even the minimal effort of enforcement would shut down entire arteries. How do you pull over a bad driver when there’s no space to pull them over?

There’s no way out of this mess except for fixing the subway and congestion pricing.
The anonymous factor does allow people to voice their own thoughts without fear. It also allows people to lie without having their physical reputation damaged. They create new fake accounts if old ones become known to spread information. People take so much information that they read as gospel. Selective reporting and the use of loose "anonymous" sources by media outlets (who have become so partisan and biased in one direction or the other) have gone on to perpetuate this problem even further.

This thing looks ridiculous.

AR glasses won't be a thing until they stop trying to put a tiny TV screen in front of your face. It needs to fill your visual field.

They also won't be a mass adopted thing until they don't make you look like an 80s cartoon character.

The question remains whether VR will still have it's time before AR becomes reasonable.

Until that is answered, VC money will continue to be sacrificed in a giant fire on the alter of getting there first.

What nonsense. You must have hung around insufferable people.
That's such a backwards-looking patent in the era of SDC.

People should be filing patents about how to make people more comfortable in what is essentially a moving room, not trying to optimize the driving experience.
Ah. My crankiness towards MS may no longer be justified.

I’m too deeply entrenched in Swift though and disgusted by the sight of semicolons in a language anymore :P (maybe I’ll dip into VB.NET and see how it’s doing.)
This was actually a pretty well grounded article compared to what I was expecting.

I'm with the author, I absolutely think this kind of thing will be the next step in computing. It just seems so obvious. Get rid of screeens and wear a headset that lets you put application windows anywhere in your view.

I'm glad they questioned a lot of Magic Leap's claims and didn't just parrot back the taglines and act like it's magic.

That being said, I don't think Magic Leap is going to be the product that "wins". It seems from this article that it's going to run its own "OS", with it's own special apps, and most likely limited integration with other stuff.

I don't want a new "device", a new os, a new "platform", I want a screen that I strap to my face. One that I can eventually connect to my Linux machine, or my windows desktop, or my MacBook. Maybe in wrong, but I feel like Magic Leap is going to die if it demands that kind of integration, regardless of how technically impressive it is.

Hololens on the other hand is something I'm giving a good amount of consideration to, because they seem to be focusing on "a screen you strap to your face".
Augmented reality standalone computers are cool, but these guys are at the same price point as the Hololens, and have three components instead of one, with less battery and a narrower field of view. Maybe they can differentiate themselves on a better development environment?

Agreed, the "let's put stories in your personal message view interface" was absolutely terrible in my opinion. I use to watch stories all the time but now I hardly ever do because it is so annoying to find them.

"Magic Leap One starting at $2,295. Magic Leap One is available to creators in cities across the contiguous US. And the list is growing daily. To help you take your first step into spatial computing, we’re going to hand deliver the device to your doorstep and personally get you set up."

The free tier is 1M requests. If they're very lightweight, it should easily handle the spike without extra cost. I've been on HN front-page a few times and the traffic is never that high.

I literally had this discussion at work today about vendor lock in. with AWS Lambda.

At my old job, we were terrible at wanting to use new shiny things (me included). We had terrible vendor lock-in with AWS, although it did make my resume look nice as I could fill it with fancy AWS products.

My supervisor was discussing AWS Lambda with me at lunchtime, and I said that it's not worth it, because any cost savings from using Lambda over a server are outweighed by the cost if we ever wanted or needed to switch vendors.

AWS lambda would make sense for large companies, where server time is more expensive than developer time. But for most companies, developer time is more expensive than server time, using shiny new AWS specific tools is just going to hurt later on.
I think the problem is that Baidu doesn't recognize 銅鑼灣 as a location. Maybe they just didn't bother to get good map data for Hong Kong.

Trying https://www.baidu.com/s?wd=%E5%8C%97%E4%BA%AC%E4%B8%9C%E7%9B... instead, I do get a result with a map, although it's not the first and the first result is a different place.
Just download it and compare to 6.0 it seems the startup time are heaps better.
Lambda + API Gateway excel at spiky, unpredictable workloads. We have APIs that are spiky enough that EC2 autoscaling cannot spin up instances as quickly as the traffic spike comes in, which means with EC2 services we need to run with a lot of headroom to absorb these spikes. This includes running at night where usage is minimal, but still under threat of sudden spikes. That gets expensive. Our Lambda costs are a fraction for us because of this.

BTW, you can use other self-hosted API gateways like Kong with Lambda if you want to cost optimize.
Growth or opportunities for growth must be present to convince buyers and investors to exchange more-liquid assets like cash for less-liquid assets like ownership. I part with $100 that I can spend anywhere for a share of stock that I hope will grow in value. Without opportunity for growth I have no incentive to part with my $100.

In the Facebook example, if Zuckerberg didn't want to grow Facebook, but wanted to still capitalize on it, he could have found a buyer and sold. The buyer would have been interested in growing it, and committed resources to doing so. Growing or Selling were the only two real options that would deliver Zuckerberg any gain. Once he decided not to sell, his only option was to deliver investors growth, so they would be willing to place their money in Facebook.

Another example would be an iOS app. There are plenty of apps in the app store where the developer built it, put it out there, charged $0.99 and that was it. If the app meets a need, this can work for a while, but eventually either demand will change or competitors will arise and the developer would either need to update/grow their app to maintain their revenue stream.

Growth is a fundamental piece of the financial system and eventually everyone decides to either grow, sell, or undercapitalize their asset.
