I teach math. I am impressed that when you read these comments, very few of them show evidence of having read the article.

The article is about experience with actual students, with ones who have a real knack for the subject and would learn it despite what any teacher did, and with ones who waver. There proves to be a better way, which the article describes in various ways, including as "sense-making."

One of the problems here is that everybody has a pre-formed opinion and does not seem to want to risk having to modify it with the evidence of experience.
and all the script kiddies will find it great fun to send out those "collision" signals on a busy roadway just to screw with people. the futures gonna be great!
> I am constantly seeking to remind her that it is a lack of lightheartedness that is at the rock of extremism....I know the likelihood that I'll ever succeed is small, but it's important to me to wake people from what I consider to be a way of thinking that impairs sound judgement (say, when voting or choosing how to react to world politics). I'm not against religion or the right to practice religion, just its ability to cause hysteria.

Have you considered what is trivial and lighthearted to you might be deeply offensive to her? You might say "that is exactly what I am trying to change" but to that I would say "why". Unless a person is explicitly causing harm either by doing anti social things or inciting people with speeches to do anti social things, or forces their belief system on you, what someone believes in or finds funny is no one's business. I guess your mother isn't any of that - she's just a law abiding woman with a certain religious faith that makes her life feel meaningful - so leave her alone.

It also seems that you are to quick to relate religious people with religious extremists, which is flawed. The whole idea of atheists having to "wake up" religious people is quite cocky and indecent. Also the assumption that religious people have "impaired judgement" is deeply offensive. If anything, its the atheists who are extremists with impaired judgement because they think they are better then the religious people.

I used to be one of these cocky atheists in my early 20s and used to constantly bother my deeply religious mother until one day she told me off. She basically said why do I bother her when she doesn't force me to follow the religion (she did like any parent till I was a teen and rebelled and then left me alone). That was a wake up call to me. Of course, my cockiness will come right out whenever a religious relative or colleague tries to mock my lack of faith or give me unsolicited advice with religion based arguments. But in general, I don't try to be holier than thou and look down upon religious people or interfere with their faith.
It's interesting that you mention 8 year olds, because 8 year olds learning basic maths need to go through the same process.

First kids need to be drilled to pick up the basics such as tables of multiplication, the understanding comes afterwards (for some). This is how maths has been taught for ages, but not so long ago common perception under teachers changed: people started thinking, wouldn't it be better to teach kids the ideas and the reasons why basic math rules work, even better, let them discover those rules them by themselves, and get rid of those mind numbing drills?

After a couple of decades, the common perception has switched again: the answer is 'no' [1]. To be able to grasp the ideas behind math rules, your brains have to get familiar with the basic concepts first. And that just takes time and practice.
When those basic concepts are engraved in your brain, only then are you able to start playing with them and build higher abstractions.

Learning complex mathematics is not any different.

Ask HN: Simple steps for thwarting web tracking
Despite the relatively good news this morning (http://www.nytimes.com/2016/10/28/technology/fcc-tightens-privacy-rules-for-broadband-providers.html), I've been thinking about how best one can alter their browsing habits in order to best preserve their privacy.

These are my steps:

* Browse only in incognito/private mode

* Use adblock and/or privacy badger plugins

* Use a VPN

* Do not search/surf while logged into gmail or any social media

What other basic, simple steps can be taken in addition to these?

Less sweet.

I was on a liquid diet for a while for medical reasons. Ensure (and other drinks in that space) are horrifyingly sugary, and even their "diabetic" formula is disgustingly sweet and high in simple processed carbs that are a half step up from sucrose. They're also extremely low in fiber.

Additionally, though the vitamins and minerals are balanced for consuming four per day, you'd have to drink 8-10 of them daily to fill the caloric needs of a healthy and not particularly active adult. Sugar is a surprisingly inefficient source of calories on the scale of an adult's daily metabolic needs.

Soylent has a very neutral flavor that can be seasoned for a sweet or savory effect, and a bottle has roughly the right amount of calories for a meal for an adult. If you're moderately active and eating nothing else, around 5 per day will suffice.

Even on a liquid diet, I ate other things besides soylent, and I struggled to consume enough calories to meet my basal metabolic rate - below which your body will start consuming itself for energy. (Forget maintaining your original weight on a liquid diet at all.) Whole milk, you say? I was forbidden to consume significant amounts of lactose.

Unfortunately, the vast majority of options were either extremely sweet or would fill your stomach without providing meaningful nutrition (a cup of chicken broth has 10 calories!) Despite usually being a chocolate hound, after two weeks of that I would gag at the thought of a m&m. Soylent at least was neutral and would keep me feeling full for a little while.
Was Vine really that impactful? I only ever encountered a handful of links to content on Vine, and when the videos would play at all, they were typically just 20-second-long clips of something mildly amusing at best, totally disgusting at worst.

As far as the social goes, I've literally never heard someone say "check out my Vine" or "look me up on Vine" the way I hear it about Facebook, Twitter, Instagram, etc. (and used to hear about MySpace, LiveJournal, etc.…).

I'm genuinely curious: was Vine something big and impactful that I somehow managed to sidestep? Or were my experiences with the service typical?

What does "good digestive shape" even mean? I've never heard of "digestive muscle wasting" in any of the medical literature. Your digestive muscles are smooth muscle (different from the heart) that are autonomically innervated (more than just food stimulates them).

The fact that people have gone on extended fasts and then broke them without much trouble suggests a "breakdown" of digestive function is a weak argument.

I would say that a change in the biome of the digestive tract is probably more responsible for any digestive upset after breaking a fast than "muscle breakdown".
the US can't let that happen because the hegemony the dollar has over the world economy would be at a very high risk. Oil is traded in Dollars exclusively. This gives the Dollar some very powerful and unique powers. Saudi Arabia has a strong hold on the OPEC cartel.

There is a reason Apple doesn't do a PC with a touchscreen and it's simple, there is no good way to pull it off right, it sucks, it's useless and it's a gimmick.

The puck's usefulness will depend entirely on the developers. Developers who don't really pick up on Microsoft, Samsung or Google's toys.

The TouchBar might be tiny, but they showed off zero day support for it from companies like Adobe, and that's where the difference comes from.

While the Surface Studio looks sexy and is deliberately trying to mimic Apple, the fact that it runs Windows (10) on a high res screen is just a turn-off for me.

As someone who used to hate Apple with a passion and love Microsoft OSes and products unconditionally, I've finally had enough and switched to an Apple-ecosystem: while not perfect, the amount of things they consider for their products is astounding and last but not least, they ship with 3rd-party support already on the way.

And that's a key difference to me as a developer, as a photographer, as a designer and artist and as a musician.

Don't I know it. The prices for the specs are stupid and this is coming from someone with a 13" MBA for a personal machine and a 15" MBP for a work one.

I can see myself ending up with a Dell XPS 13 or similar to replace the MBA and maybe a Lenovo P50 for a work machine. Win 10 isn't a bad OS especially with a native Bash terminal now!
I'm not one to complain about paying for quality, but their pricing across the board is just getting ridiculous. There's no major innovation here to justify such price hikes. 16GB RAM limits on a $3200 laptop is bewildering to me. If the strategy here is to kill off the Mac brand, while focusing only on the iPhone, then I think they are well on their way.

If it wasn't for the Mac OS, I wouldn't even bother considering their lineup anymore.

Edit: Additional thoughts. That OLED touch bar is going to be the equivalent of force touch on the iPhone. Neat idea, that will be forgotten. Also, whose idea was it to make that track pad ENORMOUS? When has anyone ever wished they had a track pad that took up 2/3 of the palm area? I hope their palm sensing is 100% perfect.
I would guess the nausea is a learned response due to people forcing the powder on themselves. Perhaps it needs to be introduced gradually with small amounts?

I think Microsoft has sensed their weaknesses and has made a change in strategy from focussing on what works for "ordinary people" and segmented their market and is now trying to win over people one segment at a time, developers, gamers, artists. Not sure if they will find more good segments to target, but this is certainly a good strategy for winning over those segments. They obviously have a path to travel, but it seems like a good one to be on.
yes I agree, the lack of bulk would be one of the many worries I'd have about eating this regularly (if you know what I mean). Is it really that hard to go and pick up some groceries? This would probably keep you alive for a while, but is it really worth it? even prisoners get better food.

But then I'd have to avoid customs or pay an additional 15%.

While I'm not using TypeScript in my Aurelia application yet, I'm thinking about using it at least partially in the future. I also agree about the risk of Google not committing to Angular users. In response to that, the makers of Aurelia have asserted time and time again that they are trying to have a very different mindset and wholeheartedly cater to their users.
The idea behind this powder is uberidiotic, because we receive most of nutrients from our intestine microflora, and not from food per se. Diet like this destroys microflora, and here it is - diarrhea! But microfloras are unique to their bearers, there are some general types, of course. You cannot standardize food and not harm your microflora at the same time. So on place of Soylent, I'd run tests on volunteers for microflora replacement first, and then feed them powder. Could be like that: Stage one - 3 days on amoxiclav, 3 days fasting and water. This is cleaning fase. You will be sick, and have diarrhea. Stage 2 - 2 weeks on growing Soylent-compatible microflora, something like genetically modified bifiform. Stage3 - You became happy Soylent eater. But remember - from this time further any normal food except Soylent will make you sick.
This reads like the gratuitous/lazy critique of someone who didn't bother to read the actual API documentation for Web Workers. You can pass more complex data structures to Web Workers than mere strings. ArrayBuffers instances for example.
I've been thinking about this lately. Microsoft is doing the same thing if you look at it's enterprise products. Low innovation, high cost seems to be the business model of late. I wonder if it has to do with the founders of the company leaving and the reins being placed in the hands of MBA types. It seems like Bill and Steve weren't as afraid of a bad quarter as the current leadership is and took more risks as such.
Lads, the Pound has dropped about 20% against the Dollar since the Brexit result in June. Cool it.
And so do Microsoft and others as the article states. As others have pointed out[1], if you add the UK sales tax and account for the exchange rate, Brits are paying virtually the same as north Americans.

The real news is that the result of the Brexit and the GBPs 31-year low are now felt.

When prices for imported electronic goods go up by 20% across the board, I'll agree that this is due purely to the currency shift. I don't see that happening.
> Assuming everyone has 8GB of cache space on their phones

That feels optimistic. I doubt people have that much free space on their phones, especially those that don't have flash cards. Heck, a basic iPhone won't have. Even a 16GB model has something like only 12 GB free when it's empty.

> For such a mesh network, you don't even necessarily need to connect over WiFi - lower energy Bluetooth could be used too.

IPFS doesn't (currently) work over Bluetooth.

However, my main point is, that I don't think most people would be altruistic enough to participate unless they could plug in their phones on the plane.

This isn't some grand strategy, it's just a knee-jerk reaction to the FX risk/impact of Brexit.

Business leaders say "hey man all our costs are anchored in USD but GBP are worth less than they used to be so now revenue in this region is down [due to factors far outside of our control]." So they debate about the market impact of raising prices and they seem to feel that their product is strong enough to endure (and/or the competition is already doing this or will follow them).
Surface series and the hololens are non-innovative?
Yes. The article speaks of "zero latency", but that is simply not achievable with a network connection that has latency. My guess is that in current browsers, on average 90% of the latency is in the network (as opposed to rendering). So even if the render step was perfect, you would only get a measly 10% performance gain.

their pricing across the board is just getting ridiculous

This is not really about Apple pricing, since the prices went up by up to 20% for many existing Apple products. This is the result of the post-Brexit vote and its effect on the exchange rate of the pound sterling. I guess the UK will see such price raises across the board.

Of course, it's all good for the UK's export as long as they are still in the single market.

Yes, I just checked their example for the MacBook Pro, $1299 in the US, £1249 in the UK which is $1500, the extra is accounted for by 20% VAT which vendors must include in their prices in the UK.

However if I compare prices to the beginning of the year they are about 25% higher, an obvious affect of the currency movements.
Low Health Literacy – A $238B Problem
> Whitehead and Russell famously took several hundred pages in Principia Mathematica to prove the validity of the proposition 1+1=2. What is it that kids are understanding that W&R took much pain over?

W&R proved 1+1=2 in their axiomatic system. It wasn't done to prove once and for all that 1+1 is in fact 2, but to show that their system produced mathematical truths. The truth of 1+1=2 was already assumed and understood since they were kids, and that's why it was necessary that their system also produce it.

Of course PM was obliterated by Godel shortly after.
