Pure math? Not really.

Math as applied to some numeric solution or another? All the time.

I like building models and simulators, for stuff ranging from a space elevator to the sound of a supersonic rooster. I like making procedural generation models, from expanding a set of parameters into a realistic texture to making a whole universe from a single seed number.

This sort of stuff. It's more or less in the art category than anything practical.
This is a very rough equivalent of that. The area outside the stitched part is used to keep the belt synchronized if there are not parts in view, hence that wavy line on the belt in the video.
Yes, like many life changes, being barefoot takes conscious changes, like covering the deck (or more extreme, moving)
IIUC, those are cases of companies who put arbitration into a contract. That's a bit different then an average Joe hitting "ok" to an email that says the ToS of a website has changed. Arbitration can work for businesses which can negotiate and review contracts they agree too. No one reads or negotiates EULAs.
Sheer size can certainly be scary, but consider that Google and Facebook got where they are by excluding stuff people don't want.

Google has used page rank from the very beginning to show popular pages. Since then, there have been a zillion other teaks to search ranking. (Not to mention that Gmail's spam filtering was an attractive early feature.)

Facebook started out excluding people who didn't go to a particular college, and later, the friend graph helped people avoid communication with strangers.

More recently, Snapchat showed that auto-deletion of photos is something people really like, even if it's technically "impossible" to do perfectly securely.

So it's not just about big companies being in control. Filtering is a really popular feature. Companies that did it well attracted users and became big.
It represents an average, of clocks per sample. For example when in the C3 to C6 states, the clock is stopped so would be effectively zero during those tiny periods.
Why do you care? It's easy to dispute credit card charges. Most banks will overnight you a new card if needed.
Cool, a new hysterical trend. Are we done with kale and paddleboard yoga yet?
Yes. But mature projects also have larger codebases and many knobs to play with. That can make it hard to serve as introductory stuff. Focused projects have their purpose too... like what Minix is to Linux. So it's fine.

Other software to play with neural networks can be R and Scilab, not to mention others like: Tensorflow, Torch, Theano, Pandas, Scikit-learn, Caffee and many others. All of them free, great communities and videos can be found in YouTube with nice intros.

Another way to learn can be just grab Python and Numpy and roll your own multilayer perceptron with backpropagation, then play with other concepts.

Jupyter notebooks are also a great way to explore what's out there.
A New Way to Harvest Drinkable Water from the Air
Isn't MRSA something you can pretty much only get in a hospital?

> MRSA is becoming a critical problem in pediatric settings;[38] recent studies found 4.6% of patients in U.S. health-care facilities, (presumably) including hospital nurseries,[39] were infected or colonized with MRSA.[40] Children (and adults, as well) who come in contact with day-care centers, playgrounds, locker rooms, camps, dormitories, classrooms and other school settings, and gyms and workout facilities are at higher risk of getting MRSA. Parents should be especially cautious of children who participate in activities where sports equipment is shared, such as football helmets and uniforms.

Hmm ... guess not. Sounds like running around San Francisco barefoot is actually safer than doing anything at all in day-care or a sports club O.o
Technically they weigh the same but I guarantee you the former will feel heavier.
Not what you're asking about, but two things here.

I don't see how "realtime key-value DB" would work like and how would I be
supposed to use it, nor I know this socket.io thing, so you should work more
on your project description. The best would be to avoid comparisons to any
other software. Those belong to a different README section (or to FAQ).

Then, "V" name may be nice and short, but will be atrocious for searching the
project anywhere, and you'll probably run into similar problems as you now
have (would have) with buying a domain, but with a different service (e.g.
creating an organization on GitHub). Consider changing the name.
It's only about 8,000 words. Long by Buzzfeed standards, short by The New York Review of books.
This may be the most Hacker News comment I've ever seen.

There are some sectors of the magazine industry, maybe science isn't one of them, that are actually doing really well. I've been on three different junkets with outdoors magazine editors in the past 6 months, and many large brands that advertise to the Duck Dynasty crowd are abandoning digital and going back to print.

Digital, it turns out, is mostly a scam. I've written in other places about why this is, but the nutshell version is bad ROI metrics and, even worse, the incentives on all sides are so perverted that the bad metrics and rampant fraud are a fundamental structural/business problem that no amount of tech can solve.

At any rate, the jig is, increasingly, up on digital (FB and Google excepted, because they run genuine performance advertising platforms at a scale that nobody else can match), and advertisers are actually going back to print, TV, radio -- venues where the ROI metrics are old, established, widely agreed upon, and fairly reliable.

Anyway, this situation is very complex and very very very different from what the typical HN "dead tree is expensive and for losers, the future is digital!" commenter thinks. If anything is in real trouble right now for deep structural reasons, it's digital, not print.

You probably find all this hard to believe -- I did at first until I heard it confirmed by the sixth or seventh person. I know that what I just said sounds like "up is down, and black is white", but this is how it is in 2017.

Ask HN: How far free IaaS products can take you?
started working on a startup project with a friend recently. Like most of the other startups, we are trying to get up and running with a minimal budget. However, we need IaaS like aws, GCM, Azure.
However, whichever we end up using, we'll have to get most out of the free-tier offeings.

How far you went with your products with freely-offered IaaS /PaaS services? What's your realization on the experience(s)?
I sometimes do an exercise with my students where I give them a paper and ask them to tell me in 5 minutes what is the research question and the answer. Usually works well (if the paper is well written), and shows hem that they can get a good grasp of papers without spending hours reading them.
Mosh would be more widely available, outside of just this 'reference implementation', if it did not use patent encumbered OCB crypto.

Phillip Rogaway holds patents relevant to OCB. See the following for his patent grant: http://www.cs.ucdavis.edu/~rogaway/ocb/grant.htm

I think this is the primary reason why there are still no alternative clients. And specifically, no good Mobile clients.

The reliance on OCB is unfortunate. I wish the Mosh developers would introduce multiple cipher schemes so that people can move away from OCB.

Unfortunately the protocol is also pretty poorly designed, with no easy backward compatible way to do this.

For example, when a client starts a session, the server prints "MOSH CONNECT 60001 sdmDrHqo8DBdpKxtAFAUyw" where the last part is the OCB key. It should have been prefixed with the ciper type for extensibility, but it is not. So this would need a backward incompatible redesign to get it going.
Supervision trees have enough flexibility to support any architecture pattern imaginable, you got it kind of backwards. They are like trees of arbitrary architecture patterns. The idea is to limit the scope of any possible problem, so that it only affects a tiny part of the system, but at the same time reducing complexity by only having to deal with little responsibility in each supervisor. Kind of a tiny orchestration system for each service, instead of a centralized one.
While it’s good that the author got their money back at least, if it was invalid for the author to have an account for 10 years it was also presumably invalid for PayPal to take any transaction fees during that period. Might be an interesting avenue for small claims.
For everyone who hates the "plug-and-play" trips to Burning Man set up for rich kids, this story is the schadenfreude of the year. It turns out that the logistics of throwing giant festivals in remote locations are difficult! Who would have guessed?

I look forward to the deeper investigative reporting on precisely how that mess worked out as badly as it did, but the combination of promise-vs-reality mismatch and the rough PR afterwards suggests incompetence on all levels.
C++:

void f(map<int, int> m)
{
m[0] = 0;
}

int main() {
map<int, int> t;
t[0] = 1;
f(t);
cout << t[0] << endl;
return 0;
}

prints 1.

Go:

func f(m map[int]int) {
m[0] = 0
}

func main(){
var t = make(map[int]int)
t[0] = 1
f(t)
fmt.Println(t[0])
}

Prints 0.

So in C++ maps are passed by value.
In Go they are passed by, hmm, "not value".

Go could have made maps similar to C++ maps and then people could use a pointer to a map when they wanted that. As it stands maps are "different" which is not a big deal once you're used to it but still makes things a little weird if you're coming from C++.
There's a situation that springs up sometimes that is perfect for Tcl/Tk: when you need to write a small app with a GUI and you would like it to be multiplatform.

Say you want to write an app to rename files in batch, or a wrapper for Ghostscript that automates certain tasks. With Tcl/Tk you can immediately run it on most Linux distros and with Freewrap you get a Windows executable that's a few MB+your source (it's a lot better than having your users install Java).
One thing that I think could work is generating imagery from the catalogue for parts you've not seen before. Initialize a random starting position, and use bullet to have them fall into a realistic position on a plane. then raytrace from the top.

This way you could also cross-reference with part seller sites to see the going rate for a part and determine whether it's worth your time to separate it manually. Have a bin for rare parts worth separating by hand.
Homeowner Sues Over Zillow’s ‘Sloppy’ Estimate
I'd love to go barefoot, and let my kid go barefoot--we live in the country. But we have chiggers here and that's a show-stopper unless you want to be miserable for a week after.

I've been tempted to see if I can...I don't know, build up an immunity? Or get rid of them somehow?

But it doesn't seem possible.

If anyone knows a solution, I'd be happy to hear them!
The stuff which makes perl really awesome are the distributions on CPAN.

Many (though not all) of these distributions contain XS, which is a type of glue between perl and C. Most of these XS distributions are there to link to some library -- Math::GMP, for example, lets perl code use the GNU gmp multi precision math library.

Without some way to make use of distributions with XS parts, then a perl to $other_language_here transpiler is not going to be very interesting.
If papers were written better, you might not need to read them over 3 times.

There should be a paper called "how to write useful headlines for your paper."

"first pass" "second pass" "third pass" should be replaced with unique, useful, preferably memorable headlines. For instance: "Quick scan" "Deeper but ignore details" and "Challenge every assumption in every statement"

Then you haven't wasted the attention those big bold headlines get.
Having both been on the Something Awful forums and read some of the major stories there about the low points of the site's history and community dramas, this article makes sense to me. The reason why many forums, even "normal" ones about mothers, have mass social dysfunction because they're self-selecting communities.
I know you're being encouraging, but I think you're underestimating the

No, what it shows is that this project is just in maintance mode. There is plenty to be improved, but there is zero momentum.

This is hard for open source projects in general. What it needs is not just a happy user base, but also developers and a strong leader wanting to move this into the future. I think specially the latter is missing. I think Mosh was a great thesis project, but stalled after that.

It has so much potential. I wish they would push this to the next level and do proper protocol documentation and an IETF proposal like an RFC.
I think you mean gender instead of sexuality. Gender is who you are, sexuality is who you like. (I'm replying to try to help, not to nitpick.)
Other than the fact this story makes us all giggle...who cares?
It's how I got through over 10,000 papers on IT and INFOSEC. When they're well-written, I could look at the abstract, a select bit of details, related work, and conclusion. Would take me about a minute or so a paper once I got good at it. Sometimes less. Some papers were more complex or just not well written where it took significantly more time to evaluate them. All in all, though, the speed reading methods save a ton of time.

You'd be surprised. There's a fair bit of nuance to Silicon Valley that gives it an advantage over other hubs. Close to Asia / Asian VC. Engineers from Berkley, Stanford, and the UC system. Local government and finance that is willing to work with tech. Etc.
"There will always be tasks you can't automate away, so... don't try to automate your tasks away."

(This isn't to say that resilient patterns can't help you engage with potentially stressful situations OR help you get in, chop wood, and move through tasks that aren't easily automated... just that "there will always be stress/tasks/entropy/hunger/fill-in-the-blank" doesn't seem to be a compelling reason to avoid efforts to mitigate any of them.)

SpaceX to launch classified payload
Since you've admitted to making a habit of lying on U.S. government forms, I'm sure the FBI will be paying you another visit real soon, Mr. Earnest, to see if there are any violations of 18 U.S.C. §1001 they don't already know about.
I wonder whether a "bridge-across-the-void" approach would work. The idea is that a speculative optimization would not discard its original form, so that deoptimization is as cheap as a rollback. Then, when speculative optimizations are performed, they form a kind of bridging branching structure which reaches across the void of invalid low-level IRs, trying to find a safe point at which the optimization can complete.

I know that Truffle is based on partial evaluation; how close are you to Futamura #2? That'd relieve you of the burden of having to care about what an "interpreter stack frame" even looks like. OTOH I can confirm that the same kind of speculation in optimization has to occur during self-application.

It really is a thorny problem, isn't it?
You:

> I think this is a vast oversimplification. I may not remember the details of every book, but I do remember the main themes and elements.

The article:

> Only on a third or fourth reading, he claims, do we start behaving toward a book as we would toward a painting, holding it all in the mind at once.

> Nabokov does not mention forgetting, but it’s clear that this is what he is largely talking about. The physical effort of moving the eyes back and forth remains exactly the same on every reading of a book, nor have I ever found it particularly laborious. What is different on a second and subsequent readings is our growing capacity for retention, for putting things in relation to one another. We know the end of the story now and can see how it is foreshadowed at the beginning, how the strands are spun and gathered together. Rereading Mrs. Dalloway, for example, we are struck on the first page to find the comment “What a lark, what a plunge,” of Clarissa’s sallying forth from her house into the street, aware as we now are that later in the book one of the characters will plunge to his death from an upper window. At once we feel we know the novel better, or at least are more aware of its careful construction. It is gratifying.
My experience from journal clubs is that strategies like this just encourages parroting whatever is claimed without thinking critically.
Incidentally, lack of shoes was the cause of hookworm epidemic in the American south into the 20th century, and there was a (clearly) successful humanitarian effort to shod southerners. Hookworm infections stunt growth, which made some southerners dwarf-like. It also saps your energy and was one of the reasons southerners were considered lazy.

So yea, you want your kid to wear shoes, at least outdoors.

> I can't believe the direct costs of printing and shipping such a beautiful magazine don't exceed $5 per issue

A few Quora answers put the cost of printing a typical magazine at less than $1 per copy. Magazines have a special postage rate that's cheaper than a single first class stamp. That means printing and sending the print magazine could cost just about half of what you're paying for the subscription, leaving the other half to pay for the content and overhead.
I read Searle's Minds brains and logic before the commercial world wide web in a philosophy of the mind course. While the main thrust of his argument certainly made an impression, the most intellectually interesting part was the tidbit about thermostats. A few years later during a phase in my life where I was buying philosophy books, I picked up a copy...maybe in part because the bit about thermostats has utility in internet arguments if for no reason other than offering a sneak attack from behind and in part because it is a Humeian stance on the limits of human knowledge and I admire Hume.

One day, within the last decade and probably about six years ago, I realized that the source of the thermostat tidbit is McCarthy. Which smells a bit relevant here given the claim to define what is and isn't 'true AI'.

Machines as simple as thermostats can be said to have beliefs, and having beliefs seems to be a characteristic of most machines capable of problem solving performance. However, the machines mankind has so far found it useful to construct rarely have beliefs about beliefs, although such beliefs will be needed by computer programs that reason about what knowledge they lack and where to get it. Mental qualities peculiar to human-like motivational structures , such as love and hate, will not be required for intelligent behavior, but we could probably program computers to exhibit them if we wanted to, because our common sense notions about them translate readily into certain program and data structures. Still other mental qualities, e.g. humor and appreciation of beauty, seem much harder to model.

Yesterday morning it was hot here in my office and so I turned on the ceiling fan: it was not so hot as to close up the house and fire up the AC. My human reasoning was exactly like that of a thermostat. One of the things about Humeian rigor is that one does not get to pick and choose the comfortable path when thinking deeply. The other thing about Humeian rigor is it's still OK to head down to the pub for a pint at the end of the day.

Anyway, 'true AI' is always over the horizon. Once we see how the parts are attached the technology is no longer so sophisticated as to be indistinguishable from magic.

More or less this, except with a simpler way of allocating fractional scores: simply divide the value rolled on that die by the largest such value on any of the dice in the set (or, equivalently, round to either 0 or largest-such-value and skip the division step).
That's clever!
