The fact that this seems demonstrably impossible on its face, and yet he is raising money, always makes me curious.

During the 'Star Wars' period in the US when the military was going to buy up thousands and thousands of launches to low earth orbit there were probably 1/2 dozen companies pursuing a single stage to orbit (SSTO) type solution. Gary Hudson, the CEO of Rotary Rocket (one of the SSTO companies at the time), gave a great example that showed that because the atmosphere was thick at ground level and thin at altitude you wanted a velocity that proportional to altitude. As he explained it, everything you do to a rocket to reinforce it adds weight, and every pound you add is another 90lbs of fuel (or what ever your mass fraction is). In that way your rocket could be as delicate as a feather if you went very slowly down near the ground and hypersonic near the edge of the atmosphere.

But systems that attempt to impart enough kinetic energy at altitude zero to allow the rocket to coast to orbit require a rocket that is structurally extremely rigid because it withstands both the force of acceleration and the atmospheric drag at its worst. That is astonishingly hard to pull off.

I a serious challenge, first you have to actually start at higher than orbital velocity because you're going to exchange a lot of energy with the air around the air frame. Volcanoes are currently the champions at throwing things up into the air, Mt St. Helens through ash over 100,000 feet up. But if you start your orbit going straight up you won't be able to miss hitting the planet post apogee. The more angled you make your initial shot, the more air you have to go through before you are in space, the more energy you're going to dump in the atmosphere, and the faster you'll have to start.

And all of that makes me really wonder about an engineering solution that fits within all those constraints. What ever it is, it will be super amazing.

Yes, voting is a thing in Russia. No, you won't find yourself in Siberian Gulag (what is it?). Just because most of Russia citizens chose Putin doesn't mean that there's something wrong with voting. He's considered by most people as best president of Russia since Stalin, so it shouldn't be a surprise that Russian people like him (and, of course, enemy governments trying to paint him black, because he's not bowing before them anymore).

IT crowd, of course, won't agree. Well, too bad, because minority does not dictate to majority in democracy. Before US elections it was hard to find anyone who would be pro-Trump, everyone was liberal. It gave the impression that Clinton should have 99% of votes. Well, it didn't work that way, it turned out that there are a lot of citizens who voted for Trump, even if they didn't post a lot on hacker news. It's the same with Putin. Older people vote for him. Government and state workers vote for him. Businessmen vote and support him. Of course few loud liberals will shout everywhere about unfair elections, but it doesn't mean that they are really unfair. Putin's support is enormous in Russia, like it or not. You may call it brainwash or whatever, it won't help. There's no other leader who worth a vote.

Sorry, I hate political posts, but such naiveté makes me cry. No, there are no Gulags in Russia, if you really think this way, your brain was washed by western propaganda even more than average Russian's brain.

I agree that for C it’s mostly the ecosystem i.e. external tools & libraries. There’re just a few features in the language and runtime, such as debug heap and the preprocessor.

But C++ has a lot to offer besides tooling. Modern-style C++ (template containers, smart pointers) solve the majority of safety issues solved by safe Rust. But C++ doesn’t hide these raw pointers behind safe abstractions, and that higher level safer stuff is optional.

For specific features helping with raw memory manipulation see e.g. routines from <algorithm> header, http://en.cppreference.com/w/cpp/algorithm They are part of C++ standard library, and yet they support dangerous C arrays, because raw C pointers double as C++ iterators.

Russia has been infiltrating American dissident groups for decades. Just as every country infiltrates dissident groups in its adversaries. Way back in the day, it used to be mainly left-wing and anti-war groups. But in recent decades, they've increasingly targeted libertarians, Tea Party, militias, white-power/racists, and whatever.

I upgraded my personal laptop to NixOS 18.03 (currently still nixos-unstable; the release branch hasn't been cut) a week ago and I've had no problems

You can switch which version of Nix you're using whenever you want, and you can install multiple versions of Nix side-by-side if you want to, just like with any other package. To install Nix 2.0 on an older release of Nixpkgs/NixOS, just use the package `nixUnstable`. You can install it with `nix-env` if you want to try it out right now.

The only real differences between a typical upgrade and upgrading between releases are:

1. You'll need more storage space for the course of the upgrade, because most of your dependencies have been updated.

2. You might have to change your config up a little, because a few packages have been removed, renamed, or are out of date.

You still get all the nice rollback features that you're used to, and if Nix 1.x is part of your old system profile and 2.0 part of your new one, when you roll back, Nix will roll back, too.

To more directly answer your question: NixOS 18.03 will indeed include Nix 2.0.
When you say JS hell I'm assuming you mean because Rails wants to be your JS bundler? Why not just have rails output a div with an ID? And then use a separate bundler such as webpack to generate a JS bundle?

At the end of the day Vue-cli or create-react-app ultimately just generates static assets. Adding your statically built SPA into a Rails app should be no harder than adding jQuery. Rails should not need to know about webpack & vice versa. The key is to build components not a full fledged SPA. Pick either Rails or Vue router. If the former, Vue is just a component/view library, don't treat it like a framework.

If those attackers attacked police or gov't, they may call themselves a freedom figher. But If a guy randomly kills innocent people to show their agendas, he is definitely a terrorist, which was what happened in Xinjiang and other cities in China by some terrorist groups. Unfortunately, there was some western press quoted terrorist when they were covering those attacks.

Some children are fine after getting adopted. Others have issues. For example, the adoptive parents of the recent Florida school shooter tried to get their adopted son help, but he never did well, and apparently completely fell apart after his adopted mother passed away.
Moc integrates beautifully with cmake and "all" other build tools. There is no need for the interface builder (though I hear people seem to like it, barely tried it myself).

No need to use their smart pointers either, I certainly never have. Never saw any reason to since C++11.

No issue at all mixing with C++11+.

> We apply the ToMnet to agents behaving in simple gridworld environments

> We argue that this system -- which autonomously learns how to model other agents in its world -- is an important step forward for developing multi-agent AI systems, for building intermediating technology for machine-human interaction, and for advancing the progress on interpretable AI.

I can see how this is an important step forward in gridworld, but I'm missing the point why other standard machine learning methods would not be able to learn how agents react.

Edit: Great title for sure.

Yes, because that would be a reasonable explanation for the downvotes.

Most of the time people talk about “black on black crime” they’re not trying to make a sound statistical argument, they’re using it in service of some larger racist point. So yeah, when you start talking about “what about Chicago” or the shape of people’s heads, people tend to put you in the same bucket at everyone else who seems to be really interested in certain facts...
I'm sure this will be unpopular, but:

I once had a psychopath like this turn up in my life. Like a lot of these stories, it escalated slowly, one creepy / inappropriate thing at a time. There really is a frog in hot water effect in play here. If you haven't experienced it, it might be hard to understand why someone let themselves be in that situation at all.

What I don't understand, however, is why people don't deal with it decisively once they realize what's going on. When the person harassing me tried to cross an un-crossble line, I beat them within an inch of their life and then drove them to the hospital. I stuck around to talk to the police if they showed up, but they were never called.

I stopped in the hospital the next day to make sure this person wasn't going to bother me again. While I don't revel in this -- I see it more as more instinctual than intellectual -- the person literally shit in their hospital bed when they saw me in the doorway. Putting someone in a position where they have lost control has a profound psychological effect -- it works on psychopaths as well as their victims.

Yes, there was a chance that I could have gone to jail or this person could have tried to retaliate. But I accepted those possible outcomes and did it anyway. People risk their lives / well being all of the time for things a lot less important than their lives and well being (BASE jumping anyone?). I don't regret it one iota and I'd do it again.

And this, of course, leads to selection bias.

You hear more about the ASF retiring projects because the ASF has a whole process around it that's publicized.

You don't hear too much about some one-man project that stops updating its GitHub all of a sudden. You hear about ASF projects dying becuase the ASF wants people to hear about it.
i think this is due to two human traits/biases, 1) seeing something wildly out of the norm leads to doubts about one's perceptual abilities immediately after the fact (in other words, did I just see that happen, I know I saw it, but that can't have been what just happened...) and unless you write down careful notes immediately you will doubt that it actually happened. 2) people want to be right because it makes them feel safer that the world they know is the world they live in, hence people will hold out hope that all the weirdness can be explained away (and sometimes it can).
> They walked right into a big problem because convenience or apathy about risks trumped everything.

Well, or just lack of knowledge, and lack of knowledge about lack of knowledge. I think from our positions it's easy to overlook that. Sure, it seems like people are becoming more technically literate, and they are, but I think when it comes to knowing what you can do, and knowing what you should do, the latter comes well after the forming in almost all exploratory loarning (which internet usage mostly is). We've heard the historical stories (myths), that impart this knowledge. Usually we've lived a few cases of it as well. Even then, it doesn't always take right away, or we get caught out not heeding our own advice. I can't fault a largely novice internet populace for not having had the same conditioning we have.

That doesn't mean they are off the hook though. You're right, there's a shitload of ignoring the signs in favor of convenience and general apathy, it's just not the entire story.

> If anything, history has shown we have to use things like regulations to force market participants to behave more safely on average.

I agree with regulations. I just vastly prefer them to target the specific problems and not try to get too complex with mechanics. Sometimes that requires really looking into the problem, and it can be a hard sell if the general audience for choosing/voting the implementation doesn't have enough knowledge. In this case, I think a lot of the problem all stems from using personal information as currency. Strong regulations on the collection, notification, maintenance, and ability to force removal of personal information by remote entities would make what the real cost is of the systems obvious (you know what they collect and how it's used, or in some cases you know what actual money you pay since that will become a much more viable model again). Open source cometes well in that market, because the actual costs are all apparent instead of hidden.

> We probably need a way to quickly present that when they make these choices.

I have hope this is a problem that will be mostly solved through the normal way societal best practices are passed down, from mentors (parents, teachers, trusted authorities). We just need to get to a point where the mentors actually know this stuff, which requires time and them being bitten by it and learning the hard way, or reading about those stories, or eventually learning it from their mentors. When your Mom or Dad is usually the one that cautions you at an early age to beware any free service that might be trading on your personal info, we've reached a good equilibrium (but we'll still have issues with those that don't have as much access to mentors, which is a constant societal problem).
Well said, and thank you. What you said reminds me a lot of the first few pages in the first chapter, The Function of Education, from Krishnamurti's Think On These Things - a good read.
An obvious one drops out if you take apart the term "politically correct" itself and think about it: the value that people should independently make their own judgements, potentially against pressure to conform. That's incompatible because political correctness requires conformity; either to a political authority or a zeitgeist, from which an individual is not allowed to stray far.

Former satellite telecom engineer here, have built high capacity two way C, Ku, X and Ka band earth stations. Two big problems with China:

1. Smuggle rooftop CPE into country? Manufacture domestically in grey market factories?

2. Very low cost for Chinese law enforcement, in Xinjiang, to buy and use portable spectrum analyzers to locate the Tx frequencies coming from a 30cm-50cm sized rooftop phase array antenna, aimed at the sky. To be a viable satellite broadband product it has to have a fairly strong Tx (in EIRP). No matter what band it is in from 10.5 up to 70GHz.
The rules are bent when deemed useful. Suggest a better title to the mods via the Contact link in the footer. I've seen it done in the past.
> Psychopaths are mutant parasites.

They're not literally parasites or any more/less mutated than the next person whose genes are different from their ancestors.

Hyperbole like this is really destructive and close-minded. Consider if you lived in a world of psychopaths and you were the rare empathetic one. If the greater population openly regarded you as a mutant parasite, would this alienation inspire you to behave in a pro-social way or an anti-social way?

You're being downvoted because most people that don't know Russia's post USSR history blindly follow the propaganda without questioning why many blue collar Russians would actually be pro-Putin.
This is a poor example for making that point, in the sense that it lacks a moment of realization or revelation. All this example carries is a technicality of yet-to-be-inidentified faith, but not even a hint of justification for considering the contrary. An open mind is something to test and critique but not merely punish or condemn, as this example attempts. A human should be expected to act on probability and defend against risk to the best of their ability and awareness, and it is the point’s failure to sympathize with that which makes it moot.
Many prefer it, though it may be considered redundant in a container.
Well said. West always sees or interferes into other countries without knowing any cultural, religious or political background. And on another level that is not also different from dictatorship. I live on the other side of the China (Pakistan) and too my observation Uighers are little bit or angry (not finding good word). Few years back it was not safe to roam freely in Urumqi and everyone used to hang daggers of all king around their waist. Sometime fierce fighting might erupt on small pity things and people get slaughtered more like the situation American are having with GUNS right now.

That's nothing like what happened in the article.
It's funny, if an author with a book to peddle repeats the mantra enough times..."China is innovative", it might become true.

And yet, what evidence does she raise?

"the electronics were assembled in China; almost never were they invented in China"

"paying with your smartphone has become the norm"

"bikeshare firms"

"China has the largest number of unicorns outside the US"

Nothing that would define as innovations. Let's ask ourselves. What consumer innovations has China come up with in the last 40 years that is known worldwide. Think hard. Maybe none? one? Now compare that against Japan in its 40 years rise.
Dude you seem to have a problem. Beating folks into one inch of their life looks to me a significant overreaction.

Literally. We packed up steel mills, and shipped them there. We can blame it all on Nixon and Kissinger.

Welllllll, most people are way more pacifistic than you are. I can't think of anyone I personally know who's beaten someone else up. For most people, once they've ruled out violence, they've left themselves with no good options.
That seems like a decent idea but a bit tedious for the voter. I also like the Stack Overflow model where each downvote costs 1 of your own karma points.
Convolutions are mathematically defined by application of the same kernel at each possible position. If that kernel has finite support, you also get locality. The visual cortex has locality, but without weight-sharing between functionally identical neurons, it's not convolutional.
First, deriving is just pointer arithmetic and doesn't copy anything. Second, standard flat closure representations already involve copying parts of environments, with any sharing problems addressed by assignment conversion (turning variables that are assigned to into mutable cells, a reference to which can be copied into however many environments is necessary).
The hard part is that anesthesia is not just for comfort. I am not a doctor, but having the body in a low excitement mode for complex surgery must be an advantage.

So resistance to anesthesia could mean no surgery beyond the most basic ones.
Just dispose of the straw properly.
In evolutionary nomenclature they call this frequency dependent selection. Some trait can have a selective advantage and low frequency but the selective advantage is lost as the frequency of the trait increases in the population. Also, I think you analysis is spot on. This trait is preserves at low frequencies because it has been benefited from positive selection in the past.
