Yes I've heard his position before.

It is probably correct but very difficult to solve for, it can take centuries, which is not what most people want to hear. Cultural shifts are faster than biological evolution but are not always as fast as many people suppose.

Personally I believe in the use of eugenics for both blacks and whites in order to create an improved type of human. We know high IQ has, among others, the side affect of sharply declining propensity for violent crime. We know people with good health are able to think longer term than the sickly.

This goes way beyond the usual discussions but I think it is on the table whether people like it or not. I realize that the majority of people think this issue was laid to rest mid-twentieth century, but it is obvious those questions were always going to come back and it is only a matter of time. We've already been doing moderated forms of eugenics for decades except we've given it a hundred other names.
On #1, although TensorFlow has well-supported APIs only for Python and C++ as of now (see https://www.tensorflow.org/versions/r0.9/api_docs/index.html ), support for other languages is on the way (search Google for specific examples); moreover, TensorFlow can be readily deployed as a service (see https://tensorflow.github.io/serving/ ) in mixed-language environments.

On #2, I agree: most people will use higher-level AI services developed and provided by third parties.

How about we revisit this in, say, three years, and see who turns out to be right?
If I had this sort of question, I'd probably ask on ServerFault.

Good luck.

At some point there's only so much you're able to do.

Once had someone ask me how to send their bank account information to someone. I asked why, and they proceed to show me an email from a scammer. I told them it was a scam, and their response was that I was trying to keep them from making money.

First thought was okay, I'll prove it's a scammer; scammer and the person had already exchanged a number of emails, which I exploited to get more information from the scammer.

Using bit of social engineering and data leaked from the scammer, I was able to discover the scammer's exact location.

When I confronted the scammer, they demanded to know how I knew where they were, then stopped responding.

The person that originally asked me how to send bank account info - having watched everything I had done with an explanation added - blamed me for chasing away a valid opportunity.

Week later, scammer contacted them again, and they sent cash requested by the scammer via mail.

Should the bank have asked them what they intented to do with cash withdrawal? Should the bank make sure they're not lying? Is the bank responsible?

If yes, I disagree.

(Scammer was on a street in Lagos, Nigeria.)

that's not the common understanding of Terrorism. That's just war.

I'm sympathetic to anti-Iraq war views.

Less sympathetic to those actually against the war. Most seemed like they didn't want any response to terrorism at all, which is unacceptable.

There's an ideology out there that wants to come to my country and kill me and my family. I'm perfectly fine killing those people first - or at least making sure they can't come here and commit the ultimate hate crime.

Has something changed? I don't see the string "All the food you need" in the article (or anything like it... possibly I missed it).

Anyway, in Japan the amount of rice that one person historically has eaten for one year is 1 koku (which is about 150 kg). The yield for rice is about 0.41 kg per square meter. So you need well over 300 square meters to grow enough rice for one person for one year. That doesn't include other vegetables or fish (or whatever).

In Walden, Thoreau describes self sustenance and living off the land. I believe he talked about farming a quarter of an acre, which is about 1000 square meters. Many people doubt he was able to rely completely on that quarter acre.

You can get some extra efficiency if you build vertical grow systems, but even your 12 m^2 is a pipe dream. Their 3.5 m^2 system will provide snacks at best. So I think you are right to be skeptical.

Of all the lisps, Racket appeals to me the most. It lacks the many warts that common lisp has, and has a very clean feel to it. I had tremendous fun solving problems on Project Euler and Rosetta Code using Racket. I highly recommend it for anyone even remotely interested in learing a lisp.
In the US, you pay businesses by sharing your account number(s) with them. They initiate pulls from their infrastructure, which your bank responds to without consulting you. (You may call them after the fact if you disagree).

Your account number is a "secret" shared among potentially hundreds of merchants and all it takes is one of them to leak it.

Online banking webapps are mostly a read-only view of your transaction history. Sometimes they are capable of pushing money out, but for a new payee this generally requires phone verification, and in all cases it sends a lot of emails and takes a few days.

But even just by virtue of having a password (which you have not shared with every store you've ever visited) it's already much harder to attack online banking than it is to make fraudulent credit card or ACH transactions.
My portion sizes are small and I eat ~8 times during the day. That being said, I’m still on a mild form of calorie restriction, I think. If I don’t eat for over 3 hours and then start some physical activity, I sometimes start to feel weak and sick. I don’t think I could function if I tried to fast for a whole day.
The article says the material has better biocompatibility than currently used alloys, so biocompatibility wouldn't be a motivation to do that.

Still have to think about other measures of strength and the processes required to make parts out of it.

More: The paper mentions bonding the material to the surface of ceramic materials to save weight.

I think to a good degree experience in the subject matter also comes into play with this. If your bread and butter expertise lies in a certain area and you were asked to write a small self-contained application in that area from scratch, you probably end up with something much closer to the goal than the white triangle on a black screen.

I found it very enlightening to sit through the almost full 48 hours of Notch programming some Ludum Dare entries which he streamed on twitch.tv. The end product is often very hackish, but that's exactly what this article argues could be a strategy to success. In any event, you can tell that he has programmed similar exercises many, many times in his life because certain things that would take me days to get right, he just writes down more or less without thinking.

Not writing your own engine is also a recommendation that can be seen from two sides. Of course, for a lot of us, it is tempting to go and try writing a re-usable, nicely abstracted and modular piece of software. But for a 48h jam, that can often be the wrong direction, because you get side-tracked writing your nice game engine and meanwhile forget to actually write the game.

However, at the same time, referring back to the aforementioned videos by Notch, he likes writing everything from scratch and not use a pre-existing engine because it can give you full control over what you can do and how, which for a 48-hour jam might be what you want.

(Notch and these videos have been the subject of discussion on HN many times before, so there's probably no point to going down that road here again. I personally find it sad that he doesn't seem to stream any more programming vids.)
Ads have always been targeted; they're just more precise now, and fancier. Same tactics.

The new elite: how startups are replacing resumes
When I was younger I had an older guy (who was sort of an admired quasi mentor type) that would always want to take me out to dinner. He usually had an agenda and something that he wanted to know. But at some point he said that "he really liked out interactions" and I got the idea he just liked hanging out with younger people. I didn't need the free meal (he always paid however I owned a business and made money at the time) but it felt good that someone who was older and successful took an interest in hearing what I had to say.

> I got the sense that they liked talking to young folks without the baggage that comes with interacting with their own kids

For sure. Your kids don't always realize that you are acting in their own interest (but of course there is also an agenda as well typically) whereas a non-kid-of-yours thinks you are acting in their interest.
What's he saying about a carbon tax? I found it hard to parse.

Somewhat OT but look into simpsonswave (http://reddit.com/r/simpsonswave). It's a somewhat new microgenre which mixes vaporwave with clips of Simpsons. It's interesting because the visuals evoke a very VCR feel. https://en.wikipedia.org/wiki/Simpsonwave

I think that this example in particular is not the best for R^2. He's getting a really good fit for linear (especially when his first plot is centered in a narrow range), since log(x) has a nice Taylor expansions for log(x) ~ x - 1 in that region.

For fits that are almost entirely close to the mean (no slope) I would expect to be saved by the F-test, but we're not here since there's a region where a linear fit fits the data at least somewhat well.
An arm would be simpler, but might get awkward for larger plots. Some kind of self-driving vehicle with an arm might be the most scaleable.
I think it makes sense because programming is more of a power law than bell curve. The best are not just a bit better than average but 10x or more better.
But for larger scale operations, does it scale any better than the existing technology, which is also pretty much fully automated these days?

Take soybeans. Typically you want to plant around 130,000 seeds per acre. I estimate by the video that it takes about three seconds to plant a single seed. That's four days just to plant a single acre of land. The John Deere DB120 planter claims to be able to plant 75 acres per hour.

Naturally, you can add more of these machines, but with that goes up the cost and complexity. I'm not so certain the economics would favour such a device.
It says right there: "Some of the frameworks like TensorFlow and Chainer are benchmarked with CuDNN, but it is not explicitly mentioned"

So yeah, I'm also not sure what you meant by your statement.
"data" is your own perception, however. Can you give an example of a data generating process?
Game Theory Is Really Counterintuitive
> I think what John is saying is that people commonly use R^2 as measure of model fit where something like root mean squared error (RMSE) gives a better measure of model fit (by measuring the distance from the true model)

I don't mean to be rude, but that is definitely not what he is saying. There are two important things I'd like to clarify:

- It is wrong to call the alternative measure "the RMSE". The alternative that the article was proposing was a made-up measure called E^2 which measures the distance from the true model.

- The author is not suggesting that people use E^2 instead of R^2 for any case. In fact, in almost all cases it is impossible to use E^2, because calculating it requires you to know the true model, and if you know the true model it would be very unlikely that you'd be wasting your time measuring other models.

The author makes it clear that E^2 isn't really to be considered an alternative when he called it the "generally unmeasurable E^2".
Toughness is a new term for me. From [1]:

Hardness is a characteristic of a solid material expressing its resistance to permanent deformation. The Rockwell or Vickers hardness scales are most commonly used in the industrial blade industry.

Toughness on the other hand is the maximum amount of energy a material can absorb before fracturing, which is different than the amount of force that can be applied. Toughness tends to be small for brittle materials, because it is elastic and plastic deformations that allow materials to absorb large amounts of energy.

[1] http://americancuttingedge.com/hardness-vs-toughness/
It's not as bleak as that. There are a lot of people with manufacturer-abandoned phones that would probably be willing to shell out a modest sum to get less ancient firmware. As with everything, the economics are a question of quantity and effort. A billion Android devices enter the marketplace each year.

I think the real problem is that it is just turning out to be difficult to make a silky smooth upgrade process, the kind that is consumer-friendly enough to create a mass market. It all fundamentally starts with "hack the device" and most people can't. Maybe it's just a really hard problem because it varies from device to device and base OS version to base OS version.
I'll save you some pain and heartache - move to one of the BSDs instead. Linux is quickly losing the flexibility and openness that made it great (cf. systemd, etc)
The article is about making ref-counting thread safe in an uncooperative environment (c++ shared_ptrs). If you're willing to relax one of those conditions, there are solutions that don't require giving up shared data. See Yossi Levanoni and Erez Petrank, An on-the-fly reference counting garbage collector for Java. If you buffer all reference count updates in thread local buffers, then process increments and deferments in batches with threads paused, you can use a write barrier that has no synchronization operations. Though IIRC the Levonani-Petrank write barrier assumes stronger ordering of stores than is true on some architectures.

EDIT: http://www.cs.technion.ac.il/~erez/Papers/refcount.pdf. The algorithm requires cores to see other cores" stores in program order, which is true on x86 (and ARMv8 with the correct instructions?)

This may be a bit OT, but I feel like it's unfortunate that "watts" (i.e. power consumption) is the default unit used in lighting. It's like measuring the speed of a car in miles per gallon.

Seems like it's changing a bit after CFLs came out and they started putting luminosity outputs on the packaging, but I think people still mostly go by "incandescent watt equivalent".

I have not tried more than about 8 game engines, so my opinion is limited.
Godot is very good:

* Very customizable interface
* Lots of tutorials on YouTube and elsewhere
* Good examples provided
* Script is very similar to Python, so not too hard to pick up, and again, lots of examples.
* Easy packaging for Android, Windows, and Linux on my end
* MIT license, commercial or non-commercial
* 2D/3D and live debug and scripting on the fly

Really worth trying out, since it is easy to install and dive in.

I'll have a look at React Native, but I am not a JS programmer, and all of these 'hot' JS libs, modules, etc... seem more cluttered than plain old JS. I think if I were to branch out, I'd try Purescript instead.

I emailed him in December, asking about the possibility to cross-reference VRscript snippets like you can with HTML and JavaScript. He replied he was hoping to take it in "a URI like direction", but that there was a "significant security review that needs to go on".
Some mobile phones optimise for certain popular benchmarks for example by overclocking during testing. Thus if you rerun the test over and over you would get a different result due to thermal throttling.

In application space, as far as I know the best way to test is to compare real work loads over prolonged periods of time. Getting real test data can be hard but not impossible for example recording alpha/beta users using the app.
I believe you can do pretty much everything, but sadly people are already using it for buildings bots, so there is a chance that Niantic might change it.

> Fasting releases toxins into blood stream

Nonsense. What 'toxins'? Where are these 'toxins' from? What are there effects on the body? What scientific papers detail these 'toxins', their chemical makeup, source, etc?

'Toxin' as a word has become a high-level indicator of pseudoscience and homeopathy-style unscientific health advice. If you see someone using that word, always question or ignore their advice. It's the 2000s version of the Victorian era 'impurities' which were leached or vomited from the body to return to health.
We can create them!

Suppose I take the function y = log(x) and add random white noise. The function log() and the parameters on the random white noise process are the data generating process. We could then fit a model y = \beta X + \epsilon, and then compare the "true" (first) model to our second model. When the natural world generates our data, the idea behind all this is the same: there is a process which generates the data, and the data reveals information about that process to an approximate degree.

"Two were working full-time on the venture, [...]. The third, the brains behind the technology, was part-time. [...] The technology was critical, but the two full-time founders were doing the heavy lifting to build the startup. Five percent would have been a more appropriate allocation for the tech guy."

If the technology was critical, and this third guy was the brain behind it, he deserved more. I'm sure he could find himself other co-founders to do the "heavy lifting". This post repeats "commitment" again and again, how about "added value"? If the tech was the corner stone of this company, the tech guy could have stayed home and still deserved more.
This. Anytime you have metal in the body, you want to make sure it's not going to leach into the bloodstream and cause heavy metal toxicity, like mercury or amalgam fillings do.
This article touches lightly on research in to one type of fasting (intermittent fasting), then proceeds to detail the authors' personal experience with a very different and more extreme type of fast (a one time 7 day fast).

I fail to see how this approach provides any value, nor does it even attempt to answer the question or provide the summary posed in the title.

This is a prime example of editorial incompetence in titling an article.
This just goes to show that Niantic has no idea what they're doing and completely lucked into the popularity their app has had.

It's terribly buggy and clearly totally insecure. They can't keep up with the server load and nobody had a conversation before the game shipped about protecting against abuse from people reverse engineering their APIs. This is a joke.
