When an AI is demonstrably so far beyond human ability that to even comprehend it requires the AI to help explain itself, you start to take Singularity futurists a bit more seriously.
I'll add to that. We fell into the secular homeschooler camp. At some point, it takes less effort to just homeschool than to spend endless time arguing with school administrators to challenge your child appropriately. "We can give them extra worksheets for homework." Oh wow, thanks.

A great resource for "mathy" kids is Art of Problem Solving. https://artofproblemsolving.com There are free resources, their math books are outstaningly excellent (well, they could use more excercizes, but the exposition is superb), and they have online classes. The online classes are run with a live chat room that typesets LaTeX. The pace of the classes is blistering, so not for everybody. But you can buy the same books for cheap and use them at home at a pace that is right for your kid.

We used AoPS as the main spine of our child's math curriculum. At the time, it topped out at about AP Calculus, I'm not sure if they go beyond single variable calculus yet. Anyway, after that a local university let our kid take multivariable calculus along side the freshman engineering students. We were lucky to have that resource. Next problem: when your kid completes multi-variable calculus at age 13, what next? We did discrete math and freshman engineering physics, and counted them toward the high shool transcript.

Which is another problem homeschooler's face -- the so-called "mommy transcript". When it comes to college applications, it's good to have somebody in addition to mom posting grades to your transcript. The Uni grades in math and physics and recommendation letters from university profs helped the college application package a lot. For that matter, AoPS is well ennough known now that it is good on a transcript.

While I'm on math resources, http://www.mathpath.org is a truly wonderful summer math camp for kids in the 11-14 age range. Great faculty, great staff. Now would be a good time to think about applying for 2018. Just so you understand the scale here: My kid spent all of their spare time for two weeks on the quailifying quiz, attempting 5 of the 7 questions, a couple of those attempts were a bit weak. (A good solid attempt at 2 or 3 will get you in.) If you think your child might like MathPath, I'd encourage you to download the quiz now and let your kid start pondering the questions.
I think it helped my son for me to explain that letters were just short "names" in place of the phrase "mystery number." Or something along those lines.

Like "We are just going to call it X or Y instead of the unknown number we are trying to figure out."
The outrage is enormous because the public comment period involved massive identity theft and fake comments. The position of the corruption of the comments matched the minority position. That position was echoed in the FCC. Then the guy goes on to crack jokes about how he is doing it for Verizon. Literally cracks jokes. On a stage. In front of an audience. Like corruption is now comedy.
This has been an ongoing debate in the mountain bike world for a number of years now. Direct to consumer brands have clearly been making a dent in the traditional retail model. Intense just announced a hybrid model, where shops stock demos and consumers receive their new bike directly from Intense. Seems like a win-win - shops don't have to stock slow moving inventory and consumers get lower prices year round.

This artcle explains the pros/cons in detail: https://www.pinkbike.com/news/intense-announces-lower-retail...

This was posted here a few months ago. The article indicated that a change/reduction in training starting in 2003, mainly for cost savings, was coming home to roost. I wonder if similar things are going on in the maintenance area.

It has a rather striking similarity to Maori weapons which we have extensive documentation for:

The idea is you want extra weight at the end of a club for increased momentum without increasing overall weight as much, but you want to avoid extra air resistance. Resulting in a large flat end that tapers to a handle. The base of the handle then flares out for a pommel and/or includes a hole for a string (think Wii controllers).

That said, it also somewhat resembles a cooking implement, but the specific shape may make that less likely.
I hated learning the multiplication table when I was 5. Basically, I boycotted the whole thing. It occured to me recently, why don't they talk about the holes in the multiplication table? These are the prime numbers! So easy to mention this and may have inspired my 5 year old self to dig a bit deeper.

My first real mathematical experience was in second grade. My teacher had some hoops on the floor, and was putting coloured shapes inside. Red shapes in one hoop, and triangles in another hoop. But then the problem arose: what to do with the red triangles? It was total magic when she dragged one hoop to overlap with another hoop and placed the red triangle in the overlap. Venn diagrams for six year olds.

And I still can't multiply six times eight! I have to work it out every time...
It's the main reason I don't have a LinkedIn and never will. They are a scummy company.
I like Mozilla a lot. And this extension doesn't really bother me, since it's benign.

But oh boy, do they have a talent for always doing benign and harmless things that look bad at first glance. It's almost like they want to turn away typical messaging board users.
This is one of the (few?) things that iTunes gets right. Though it's a little hidden, the entire program can be minimized into a small floating album cover.

And if that's not small enough, you can minimize it altogether and just get updates and controls via Notification Center.
ToS terms that aren’t either expected by the user, or explained in plain text without having to click through anything, are considered null and void in the EU.

By that definition, this would be unallowed modification of the computer of the user, and fall under the various hacking acts.

The more interesting thing is that this has also been rolled out to german government computers, which mostly used to use Firefox, but due to previous troubles with CliqZ and the Google Analytics in the addon menus, have already moved on to other browsers.
Shouldn't a simple back-end be easy enough to spin up such that this is not that attractive?

For example, I use Web2py[1] which includes Fabric and bash scripts to setup a server and deploy your apps. Then you get to work with non-proprietary Python, Postgres, etc.

A related story is that windows 9 isn't a thing because software used to check for windows 95 and 98 by matching the name to "windows 9".
Nope.

The reason, however (doubly so in Norway, which is basically as inconvenient as countries come for broadcasting purposes - lots of mountains and hardly any people) is that in DAB, you interleave a lot of channels in one data stream, transmitted from a single transmitter, whereas in FM, you need a dedicated transmitter for each channel.

The lower power bill is the major benefit seen from an operator's point of view.

Additionally, with FM you need to make sure no transmitters on the same frequency can cover the same area, as that would lead to interference. With DAB, they performed the brilliant trick of using multiple carriers to get the symbol rate on each channel very low; this means that if two DAB transmitters cover the same area, you get constructive interference - a signal boost instead.

The benefit of this in Norway cannot be overstated - we have (literally!) thousands of low-power FM relays to cover every nook and cranny with broadcast radio. (Denmark, home to a larger population, had a handful of FM transmitter sites.)

Hence network planning is a lot easier in a DAB network.
Author here, not sure if I can easily fix this. The WebGL check is handled by the third-party scatter plot library.
I should, they do fascinating work.
> A good place to promote this would be with secular homeschoolers. Those homeschooling for nonreligious reasons are often dealing with a bright kid interested in advanced subjects.

I don't see any reason to restrict this to those homeschooling for nonreligious reasons. There are plenty of bright homeschooled kids interested in advanced subjects regardless of their parents' primary motivation for homeschooling.
Amazing idea, it seems they're implementing Pieter Hintjens' https://www.indiegogo.com/projects/edgenet

But why a blockchain? How can you even have a blockchain if everything is asynchronous and decentralized?
Yes. In fact, after that fad it swung the other way and the Hoka shoes started becoming very popular. I will say that, however, over time I've gradually switched to less supportive shoes as I've become more experienced as a runner. I started with "anti-pronation" shoes and now are running with fairly bare minimal shoes. I think I just like the feeling of lighter shoes.
And service is what distinguishes bike shops from each other. In reality, bikes are commodity items, things you can buy anywhere and are sensitive to price. The same for computers, appliances, and most electronics. Service, however, is unique to that store and people remember good service (and bad). When I get good service at any type of store, I feel good about the experience and am more than likely to spend my money with them again. And a key point, I am willing to pay more to get it.
When I move into an apartment I like to disable all the smoke detectors in the building and lock all the emergency exits. You know, I like to ride on the wild side, and I like to create the conditions for everyone else to be at risk of accidentally killing people.

I consider anyone who starts the fire guilty of at least manslaughter though, and if they were distracted when it happened it is definitely murder. They literally forget that fire is inherently extremely dangerous with all their ever improving safety gear. So I like to keep it real and make sure that we don’t have it.
If a safety system is on the Internet, it is no longer safe. I don't see why this is so hard for people to understand - if these things get hacked, best-case is a bunch of actual physical productivity is lost; worst-case is that people fucking die.

You idiots don't stop to think about if you should do something, just because you can. Internal networks with an airgap are somewhat more acceptable, but the public Internet or accessible from a device that can be pivoted to is completely unacceptable.
What about phone battery life?
Agreed. I sold some ETH and deposited the funds into a USD wallet, which Coinbase decided to close due to eligibility restrictions once the funds were already in it.

I've had a ticket open for about a month w/o access to those funds.
I was going to call out this article on the "Untold" part, but apparently it was released before the NatGeo video [1]. The video is a good watch. I didn't plan to watch the whole thing, but it sucked me in. You really get attached to the runners.

Neither Apple's statement nor Fortune's article about the statement contains the words "ultra-powerful."

Here's the entire statement, taken from the end of the iMac Pro press release: "In addition to the new iMac Pro, Apple is working on a completely redesigned, next-generation Mac Pro architected for pro customers who need the highest performance, high-throughput system in a modular, upgradeable design, as well as a new high-end pro display."

I believe everyone physically able to should try running 13.1 mph on a treadmill just to get an understanding of just how fast these athletes run for two hours. It is incredible.
Could it be a kitchen implement, perhaps for tenderising meat or pounding bread, for example? Perhaps it served dual purpose(the 35th-century BC tire tool):

Droog: "Honey, we're going to beat up some hominids camping down by the river, I'll see you in a few days."

Droog's wife: "I don't want you hurt, Dear. Take my bread hammer with you. Give 'em a good knock on the head with that. That'll teach 'em!"

Or possibly a work-in-progress, e.g., a half-finished spoon or scoop that has this shape merely b/c it wasn't completed? e.g.,

Maybe we're looking at it too much from a "wealthy developed economy" perspective (I don't know where you're located so, that may not be the case, but it's probably a fair judgment for most HN readers). If this is an affordable way for governments to bring some Internet access to places that currently have none, then that's a big jump in the right direction.

If I may, a wonderful book called “The Alchemy of Air” by Thomas Hager is a very enlightening book on this very same issue during the late 1800s.

EDIT: I was mobile earlier but wanted to throw a bit of a teaser in here. This book (along with Hager's "The Demon Under the Microscope) are excellent reads and I high recommend them.

Essentially, there were many "doomsday scenarios" wherein the context of the late 1800s was that vast supplies of natural fertilizer were used up and people were very worried about food supplies. Long story short, the "fixing" of nitrogen from the air not only alleviated the short term issues but also had a huge influence in wars and who was in power in the early 20th Century.

Consequently, this books ends with some pretty questions surrounding the impact of what all of this extraneous nitrogen might do long term—the impacts of which are already seen in rivers and streams... but the ocean and other areas as well.
What about mechanical breakdowns? Some of those are down to negligent maintenance, but sometimes stuff just breaks. Wouldn't those be considered accidents? For instance, I've seen a tire come off of a truck before and go rolling across the road. Maybe it was negligent maintenance, maybe it wasn't. But I acknowledge that there is a possibility that stuff happens that is nobody's fault.
My son is actually math challenged and also a science nerd. This is a whole other mind-boggling challenge.

I bought math books full of words off the bargain table for as little as a dollar and, after sorting things out with his father, just gave my son the stack of books to read. No tests. No written work. No problem solving. Just read these books. That finally worked and he has a good grounding in math, though he can't crunch numbers. He is, as they say, calculator dependent. But he absolutely understands important concepts. To my mind, this is vastly better than a kid who can estimate to 8 decimal places in their head, but can't grasp GIGO (garbage in, garbage out).
Yes. So tired of hearing about this story as if it were the end of the world in tech circles - ones that would normally be opposed to increased regulation of the internet.

I predict this whole thing will be a nothingburger, and in a year there will be no major ISPs seriously trying to sell "Netflix/YouTube packages" or the like. If I'm wrong, I'll eat crow, but I seriously doubt it.
Exactly. A "Pro" laptop for use by "Pro"fessionals needs I/O like gig-e, USB3, USBC, HDMI, Thunderbolt, SD reader and an excellent DAC for the headphone jack. And I still miss the 17" macbook pro :(

I miss the days where there was a separate line for consumers/professionals. A lineup of slightly thicker laptops with I/O for days and a lineup of thin-light for students and the light would be ideal.

But instead we'll get touchbar 2.0. yee yee.
Well, does it matter if I use Chrome, which sends everything I do back to Google Analytics, or if I use Firefox, which also sends my interaction with the Addon menu to Google https://github.com/mozilla/addons-frontend/issues/2785 and my browsing history to a German publishing, ad and tracking company (CliqZ belongs to the Burda Group) https://news.ycombinator.com/item?id=15421708 ?

Best of all, they tend to have mini web servers exposing device APIs, completely written in straight C code.
That would be a valid complaint if this was an advertising arrangment, rather than one where if you watch the TV show, you learn that you can activate a firefox addon to participate in an small AR game that changes your normal web experience into a Mr Robot style web experience for the duration.

Holiday Hack Challenge 2017
I loved the axiomatic approach followed in the introduction! It builds intuition from the very beginning. At some point I could not follow anymore as the notation and the concepts started getting more complicated and I lack the math background to keep up.

One of my favorite undergrad classes was linear algebra. I wonder if there are any linear algebra books out there that follow this approach of "build the world, one axiom at a time". My sweet spot would be something aimed at someone who is not a mathematician but has some math background (like an engineering unndergrad) and can follow along with a bit of effort and study. Any recommendations?
The direct analog of Rust's trait objects is Swift's protocol objects; call them existential types. Both Rust and Swift have limitations on which traits (protocols) can be used as an existential.

Swift forbids existentials when the protocol has an associated type. Rust has a notion of "object safety" which is both more flexible and more complicated, but applies the same restriction in most cases.

I think the closest analog of Swift's `AnySequence<Int>` would be a `Box<Iterator<Item=Int>>`.
Ah yes, the "let the Wookiee win" strategy. You lose all the games, but you do get to keep playing with both your arms.

I tried strategically throwing games a long time ago. It backfired after I conceded defeat, and rather than bask in victory, the "winning" player gave me a narrowed-eyes suspicious look and flipped over my hidden cards. They made it obvious that I would have won already if I had made the optimal play on my previous turn. She was pissed, because even though she won the game, she didn't beat me, because I wasn't even playing the same game as everyone else. We have some seriously competitive people in my family, and we had a good argument about whether one was required to make a guaranteed winning move if it was possible to do so.
And yet the West seems to spend time and sometimes money to arm groups, and then fight them.
Well besides the political aspect of Germany sourcing key military hardware from what is arguably their largest regional threat, there would also be possible logistical and maintenance issues.

Also switching to Russian Helicopters (The company) and trying to integrate those into the NATO force structure would likely require a great number of changes to be made to the aircraft, which might make them non-competitive on price alone.
