The pricing is the easiest part. As an affiliate you get access to an API that lets you query it. Of course it is heavily rate limited and sometimes fails outright. Accessing certain parts of the API comes with strings attached too. All of the non-amazon prices I refresh by hand every few months.
While technically true, this is the first time I'm actually thinking "maybe I'll start using Sheets". I hate Google and giving my data away, but lately I often feel that I'm missing pleasure of easy use by avoiding all these hateful botnets. So, eh, maybe I just die before it gets actually massively harmful, and then fuck it.

We need open source implementations for stuff like that.

Great work!!! This could be amazing...if you can stimulate a reasonable number of neurons without an implant, it's a game-changer!!
You've completely missed my point. No doubt it's favorable to Walmart - they've had a team of people running the numbers and they get to set the rules.

The question is whether or not it's actually favorable to employees and whether or not Walmart will inform them of the costs they'll be responsible for. "Here's $10 to deliver this" sounds great until you realize it's $5 in gas, your insurance is going up $50 a month, and your car will wear out a year faster.
That's pretty patronizing. I wouldn't assume people are stupid just because they work for Walmart.

Maybe it could have been worded differently, but I interpreted it as being that the workers would have a hard time computing the totality of their costs, not that they are of particularly low intelligence. I suspect most people in the US don't know how to work out the financials on this deal.
You're using C in a cool way, but:

1) By using libclang to parse your own annotations you're kind of using your own fork of C language, not the standard one. You can't really bring your annotation parsing engine to some company to work on an existing C project,

2) C++ also uses plain old data structures, using 'class' does not magically introduce any overhead in structures, unless you start using virtual functions, but nothing forces you to do it,

3) I think that by stripping name mangling you actually increase binary incompatibility, because without mangling you can't know what ABI was the function compiled against. Which compiler was it? What are the arguments? Is it MS ABI or UNIX ABI? Nobody knows for sure even if it seems to work correctly for some set of arguments. Disabling mangling sure is convinient at the beginning, but brings problems and incompatibilities at later stage.

4) Given that Windows or macOS kernel drivers are written in C++ (more or less), low level access is possible in C++ as well.
Ah right, I see what you mean now. Yes, I could have worded that clearer. It should have been 'simply to continue to be a going concern', not as if companies that have IPO'd are no longer a going concern.

Apologies!
Eric Schmidt said "All of them would be better off if they used TensorFlow" - talking of the three largest Chinese AI companies.

That statement may be a bit if a reach. I used TensorFlow on a customer project last year and have several TensorFlow examples in the Cognitive Computing book I wrote last year, but, TF is one of many fine tools for deep learning.

This is unfortunate. The world needs electronic cash, for all the same reasons it needs physical cash. If it weren't for financial bearer instruments, millions would have died all across the globe over the last decade.

To understand why, you have to understand System D. System D is the global informal economy, and it is $14 trillion in size.

It provides a lifeline for hundreds of millions of people around the world who cannot operate in the formal economy due to a myriad of structural deficiencies in their economy. The only type of money that works in System D is cash. With electronic cash, the opportunities System D affords expand. Suddenly people in the informal economy can rent servers, and sell digital music online. They are not just confined to their local economy. The benefits of economic development through expansion of System D, in reducing mortality rates, crime and civil strife, far outweigh the cost of criminal activity that is enabled by electronic cash at the margins.

On the last conference held by the Chaos Computer Club in Germany, there was a talk about a covert side channel[0] using - if I understood and remembered that correctly - cache timings.

The researchers that gave the talk claimed that they could establish a very slow but practically undetectable communication channel between two VMs running on the same host.[1]

Since the introduction to Muen explicitly mentions defense against covert channels, could somebody explain to me if this system would be able to prevent such communication? And if so, is it possible to explain the mechanism to somebody like me who knows basically nothing about these things?

[0] https://media.ccc.de/v/33c3-8044-what_could_possibly_go_wron...

[1] Again, if I understood that talk more or less correctly (probably less), undetectable refers both to the OS running in the VM and to the hypervisor.
In that case I agree.

I ought to have said, "labor income tax is the wrong way to tax the extremely wealthy."
I think it's ok to vouch that. I also think that vouching too many too stupid post will make the mods remove your vouch ability, but a single bad vouch is probably not enough.

Anyway, write to the mods directly hn@ycombinator.com to get an official reply.
Nope, but if you started a business where your friends gathered to sell each other large enough quantities of bitcoin for cash you would be.

> Furthermore, if someone is really smart enough to beat the market consistently why on earth would they trade just on their own personal account?

Alternatively, if you have a strategy that empirically works, and a strategy for identifying such strategies, why take on investors to share the risk? You can scale up your own investment and leverage yourself with less regulatory oversight.

Why on earth do you think the top quant companies will leave alpha on the table for you to snatch up?

It's not so much that they leave alpha on the table, rather that there is so much alpha available, and the capacity constraints and reward profiles are so different for many of them, that individuals can prosper outside of a firm. They just normally don't, because they lack the same training (and because it's very competitive).

Personally, I think the government there is already guilty of criminal neglect in infrastructure in that country, if they go back to coal and petrol, people WILL start dropping like flies from all sorts of issues because of the air quality. It's horrendous now, if they go backwards... ugh. Hopefully Modi is smarter than that.
You can keep using Go. Its behaviour here is actually usually what you want.

To avoid the authors' issue, you can write some functions in C. CGo has a very high level of integration (you can mix languages in the same source file) and would be quite simple for the case of a setns/execve wrapper.
"It was a pleasant and extremely vivid recollection. The problem was that it never actually happened. What I was experiencing was an extreme form of a very common mental illusion: déjà vu."

It's possible that he dreamed this, forgot his dream, and then remembered it, causing the feeling of having been there before. He had been there before, in his dreams.
Odd. I just bought this on my wife's iPad. It opens, drops some shapes and then repeats. If you touch the screen it instantly crashes
The concept Hawkins considers really important above all else is the biology. He rejects deep learning as being a fundamentally different form of computation than the one the brain performs. There are are no parallels to be drawn between RNN and HTM's, really. Apples and oranges. HTM's goal is literally to try and emulate the neocortex.

my %ordered-hash is OrderedHash;
my @ordered-hash := %ordered-hash;

If you don't care for sigils:

my \ordered-hash = OrderedHash.new;

say ordered-hash<foo>;
for ordered-hash {…}

Note that you can only assign to sigilless variables when you declare them.

You could assign an anonymous scalar to it to allow you to assign to it later.

my \sigilless = my Int:D $ is default(0) = 5;
sigilless = 4;
My goal is to show people how start to think for themselves and hopefully create lifestyle business around trading or invest for themselves instead of using "buy and hope strategy" and how to do it without losing a single penny while learning and to show them the barrier for entry is pretty low...

If we want to draw the connection to cash, companies that trade in large amounts of cash are also subject to regulation and reporting. For example, U.S. financial institutions are required to file Currency Transaction Reports for deposit, withdrawal, exchange of currency, or other payment or transfer that involves more than $10,000.

Any organization that is facilitating those trades is subject to financial regulation, even if the trade is in cash. Indeed, if the transaction crosses the border even individuals carrying cash have to report it for sufficiently large amounts: https://www.ffiec.gov/bsa_aml_infobase/pages_manual/OLM_035....

If anything this enforcement is treating bitcoin more like cash, not less.

The thing I don't understand is why it's assumed that somehow the Paris Treaty is somehow enforced, or binding, or that it will even actually improve conditions more-so than independent initiative.

I personally think that the USA can achieve its goal without the Paris Treaty through personal responsibility of the states, and independent initiatives through counties, and cities. That type of independent resolution is necessary for long term improvement at the grassroots level.

The US, I don't think, can get to the level of European in terms with climate, unless the US, and its states stop being complacent, and reliant on the Federal government.
Right. $100 should be nothing for a business. It cost that to publish to the Apple App store.

Sternberg is arguing that what the tests measure isn't desirable (but presumably the implementation of the tests would be the same/similar to current tests?).

I suppose my suggestion is a little off topic as I'm addressing some criticisms of standardized testing with respect to cost/relevance to desired learning outcomes/inability for use in guiding a student's learning or teacher's pedagogy/taking time away from primary learning for test prep/and so on.

We currently spend a little less than ~2 billion a year on standardized testing, but the problems inherent in the form/format of these tests isn't changing. I believe we could get better results for much less if we turn our attention to creating a way for teacher to implement trustworthy assessments in their own classrooms and lessons. Why pay third parties so much money to do something that already being done (but which needs to be improved to make it trustworthy).
didn't know that!
Yes, I would also expect a projection rather than a crosssection. One reason could be: perhaps it would make the game too confusing and difficult?

But I'd still like to see the difference.

I can't help but find this extremely unethical. Of course you could point to lab rats in pharmaceutical research and other cases of where animals are used but from a gut feeling, seeing a microchip connected to a living animal in order to control it seems so wrong. I just cannot put my finger on why this is different to me.
> liberals and academics have tended to pretend values or virtue don't really exist

No, we liberals (academic or not) jusr disagree with conservatives (who tend to share values, again, whether academic or not) on some details of what good values are (and, equivalently, what constitutes virtue.)

Disagreeing with your values is not the same as pretending values don't exist.

> However, they absolutely refuse to acknowledge that these behaviors are virtues

I know of no liberals who would disagree with the idea that community involvement and not committing crime (provided just definitions of crime) are virtues.

Marriage is a different story, but then even many strands of socially conservative Christianity (such as traditional Catholic doctrine) don't view marriage as a general virtue, but rather as a virtue specifically for those with a vocation for it, a vocation which is no more inherently virtuous than that for either religious life, priesthood, or committed (lay) single life. It's true that liberals often see additional lifestyle choices as no less virtuous than these.

With a large batch of new incoming students every year this problem would never go away.

I asked a friend who does DBS research about this. She said that she hasn't seen any case where it made someone high, but that their implant does sometimes cause "acute mirthfulness". I was very disappointed that the best they'd found was uncontrolled laughter.
I just looked, and every post made more recently than this one (as of now) has exactly 1 point, so its not that crazy to see this on the front page.
You might be surprised. I was on the committee which adjudicated major entrance scholarships for six years, and I can count on my fingers the number of times someone said "can we get some verification of this?" We've never thought that fraud was a common problem, and when you're competing to recruit the top students you really don't want to go back to them and accuse them of dishonesty..

And (although we're revising the system and hopefully changing this part) the relative weighting of "significant achievements" of an easily fact-checked nature vs. "doing lots of stuff" has skewed heavily towards the latter; you could have a resume full of "volunteered at X" and "leader of student club Y" which would be worth as much as the difference between a 90% high school average and a 95% high school average, while containing nothing which would show up online or elicit commentary from a referee beyond "this student is heavily involved".

(We're putting together a new system starting next year which is aimed to be more about identifying students who are in some way exceptional as opposed to merely being generally all-round good people. A large part of the motivation for this is to avoid easily "gamed" metrics; nobody spends 15 years playing violin or becomes a national chess master simply because it will look good on their resume. So with luck we'll end up having less of a fact-checking problem in the future; but we're still going to have a significant amount of trust built into the system.)
I'm guessing there's a missing/incorrect OS/functionality check somewhere cause she's on iOS 8.2. Upgrading now and will report back. Also grabbed the crash-logs and will email them through.
I kept my Facebook account but deleted all my friends and most of my personal content (and locked down the privacy settings to prevent people from finding me). This lets me access content on Facebook without using it as a social network. I did this years ago and I have no regrets.
And perhaps what the neocortex needs to incorporate from intelligent machines: backpropagation?

I mean, so far we have no biological evidence of backpropagation, and it seems pretty useful.
Agreed this is an important question. I think the second question is "is the worst solution significantly worse than what we have now?". I don't know the area well enough to take a stance here, but it seems the parent is claiming there is little to lose and lots to gain. So do you agree with that, particularly the little to lose part?
India, "still a coal Goliath" is a better description. They burn a massive amount of coal compared to most countries.

They've just scaled slightly back on a massive coal consumption plan they implemented in the last few years. Nice, but hardly worth any recognition in the shadow of the damage they have already done.
What a clumsy, terrible, crappy workaround. Congrats.

This really makes me miss the Stripe CTFs. I'm guessing Google's are aimed more at top security people working together as a team, not to teach ordinary programmers how a buffer overflow acts. I usually got about 80% of the way to a T-shirt in Stripe's.

Hmm, my city gives away bike lights pretty frequently - they aren't as sophisticated (sadly) but it doesn't seem especially wasteful either way (at least I'd assume that a fair percentage of the riders using them would have bought some kind of light otherwise; and as long as they continue to work, I wouldn't expect them to end up in a landfill). The synchronization is especially fun.
waterjet, probably, and I don't think it would be too pricey since you can stack many sheets.
I feel like we're talking past each other. I'm talking about a role where you develop strategies as either a researcher or a trader. Higher up the chain, sure, I can admit there's a utility to the CFA.
I do research in the behavioral sciences. I've published a little on analysis of neural activity, although it's not my area of specialty, but I do specialize in analyses that are cognate to DL models and are often covered in textbooks on DL along with classical DL models.

My sense is that the level of understanding of how human cognition works mathematically speaking is roughly similar to our understanding of how DL works in computer science, in the sense that if you asked a cognitive neuroscientist or psychologist how someone classifies cats versus non-cats, you'd get an answer that would seem pretty similar to what you'd get from a computer scientist. The behavioral scientist might go into a lot more detail about certain issues, but that's because the biology is so entertwined.

However, I'd also argue that we really don't know much about how human (or any animal) cognition works, and I'd also argue that our understanding of DL is fairly poor, in that a lot of it is tinkering and seeing what happens, without a deep understanding of why it works. There isn't a theory of DL in the same way that there's a Martin-Lof theory of randomness, or a Kolmogorov theory of algorithmic complexity, or a Fisherian model of inference.

Also, the sort of tasks currently involved in AI research is a tiny subset of what you encounter in neuroscience and psychology. Most of what is a hot topic in comp sci would basically be classified as perceptual tasks in human behavioral science, maybe at a slightly higher level, and maybe motor control. That leaves things like conscious versus nonconscious processing, reasoning, the role of emotion in decision-making, uncertainty valuation, creativity, etc. etc. etc.

I agree that the processing power is an issue but it's only part of the puzzle.

One thing that illustrates the complexity of the issues involved, and how we've only begun to scratch the surface, is the article's assertion that comp sci should borrow more the idea of sparse representations from cognitive neuroscience. I thought that was interesting, because in a lot of ways, one of the major trends in the last ten years in human neuroscience is away from this "sparseness" idea. It was a common assumption maybe 15 years ago, but now people routinely get excoriated for invoking that idea. The current paradigm is one more where a lot of pathways/circuits are being recruited simultaneously. Statements like "you might use 10,000 neurons of which 100 are active" would lead to ridicule. The intuitive way of explaining the problem is that even while your brain is trying to decide if you're perceiving a cat versus something else, it's also processing the consequences of that decision along about 10 different dimensions, the implications for the rest of the stimuli coming in, along with a number of other things we just don't understand.
