Sounds like USSR's education system. A high school would require 8-9 classes every semester, and you don't really have a choice about which classes to take. You have to take physics, literature (world and local), chemistry, "russian" (similar to composition/creative writings in US schools), math, art, and so on.

There was a lot of complaining about the classes -- most people don't enjoy knowing both properties of organic acids and major themes in Fet's poems at the same time. And many people would feel some classes are mostly a waste of time. Still, it did allow one to discover what they want.
Still it does work. It's may not prevent foreign government for getting electronics, but it increase costs significantly and kill local commercial companies in that market.

A restaurant can have their rent doubled or tripled in a market like NYC, making profit for almost any food business impossible.

Lots of beloved spots have closed down here and have been replaced with condos and drug stores.

Even aside from this, and as others have pointed out - restaurants operate on razor thin margins. A large confluence of variables, some more controllable than others, need to come together in just the right way for a restaurant to have a chance of succeeding.

Another problem with DCA is that it's a classic case of "timing the market". If, over the course of those 3 months, the value of the asset you're purchasing consistently increases, you'll 'lose' money in the sense that your dollar will have less and less purchasing power toward the end of the period.

There's a good discussion of this strategy on the Bogleheads wiki: https://www.bogleheads.org/wiki/Dollar_cost_averaging#Dollar...

tl;dr: If you think the market will continue to go up in the short term, lump sum will always beat DCA. A better rule, however, is: do not try to time the market. Just invest when you can.
I completely agree, but I can't see how that contradicts anything I just said. Using "of" here is not an example of "language evolution" any more than confusing "to" and "too" is.
Very cool!

Also this is mindblowing, logging keystrokes from a standard keyboard using wifi.

"we show for the first time that WiFi signals can also be exploited to recognize keystrokes. The intuition
is that while typing a certain key, the hands and fingers of a user move in a unique formation and direction and thus generate a unique pattern in the time-series of Channel State Information (CSI) values"

For the same reason the government requires chips made in the US for Classified uses. If a fab is in another country there is always the possibility that the design could be compromised. Even shipping chips internationally can cause this concern as the chips can be swapped out. This isn't exactly a new concept...

I couldn't trust it. Not that I know that product specifically, but given previous working with Intel products outside of their X86 line, it will likely be EoL'ed in a year or so.

Ive been bitten by a few of their "Maker things". Faulty firmware, no support, no documentation, faulty I2C.. All sorts of things. And unless I have a timeframe how long they plan to support it and sell it, I just can't justify using it in any product I have or plan to build.
They're correct. People cannot spot BS and learn from it, including you and I. We'll put much effort into mastering a certain area of reality and truth, and find other horizons clouding over by the day: we cannot, as humans, reality-check everything we're confronted with, because it's too much. We're not shepherds or subsistence farmers anymore, with a world tightly constrained and comprehensible. Our world expanded, leaving us behind.

I'm tempted to call this an iron law and suggest it's why we've never spotted alien intelligence in the so-vast universe. Perhaps intelligent species inevitably turn to expanding communication, and drown in it very quickly—their efforts turned to zero-sum gains, eventually triggering their destruction one way or another.

In some ways the 80's show is even more over the top than House of Cards but I only watched season 1 of the US version where they changed the pivotal death scene. It seemed like they were planting the seeds to match the UK series finale, though.
I've tried going faster but found that I had to concentrate too hard on listening to leave time for reflection during the listening, which is the whole point for me of listening podcasts. I wonder if a blind person struggles with similar issues, where they have to dose the speed reading to allow them to actually think about what they heard.

This is a problem across the DoD, not just the Navy. I've seen it first hand in both military and civilian sides of the USAF. It's comparable to the degradation of the US public schools with extensive testing. The tests that start as attempts to evaluate and quantify effectiveness become the goals themselves, rather than measures of the true goals.

For more examples, Objective-C does this on 64-bit, and many Lisp implementations use it. Swift uses it for certain enum payloads.

An interesting variant is to stuff your pointers into the payload of an IEEE754 NaN value. This is popular in JavaScript, since JS numbers are IEEE754 doubles.
Ancient Athenians adored freedom of speech. Naming a warship after the very concept.

You probably look like a target for other extremist groups (Islamic terrorists, gangs, etc...). No one is talking about speech that incites violence though.

They're talking about social media and the definition of "fake news". As I've come to experience in my life a lot of people don't even realize how biased their points of view are.

Data and statistics can be manipulated to support certain points of view. Lots of fallacies are regularly exploited by articles of all types on both sides of the spectrum. If you leave a group of conservatives to define what is fake news and what is not, you'll get quite a different list than if you left a group of liberals to do the same.

There's a real slippery slope here. Free speech is as much a social convention as it is legal protection from the government. Facebook has a near monopoly on social media. Google has the same for search. If Facebook and Google get to be the arbiter of truth, then free speech is lost.
It's not all that different from accelerators partially funding startups and associating themselves with the successes as long,as they want. I think it's arguable earned.

Tangentially, journalists almost, as a rule, put a narrative on events, even those that really don't have a narrative (which is most things under Current Events) E.g, when a story focuses on someone's personal story through the time of events, that becomes the narrative lens.

I'm not fond of this approach, because it sets up conflicts and limits the view of events to the specific, when really, as someone far away, the specific isn't useful in understanding how it is actually news.

Ask HN: Best Market Research method for ideas?
There are a number of methods out there that are used to conduct market research on ideas before any code has been written.

Here are the methods I have found:
1. Sales Safari by Amy Hoy
2. Market Map by Pat Flynn
3. Ad Words from Start Small Stay Small Book
4. Customer Development interviews from the Running Lean book
5. Traditional SEO analysis, from many of the affiliate forums like BHW.

What method do you use to investigate the potential for an idea before you start creating it or writing any code, and how has this method worked for you?
I've seen examples of all these in nature, even studied and discussed them as part of my undergraduate degree. Humanity is not special in any of these respects.
We already run vehicles in 0.14 atm environments. The issue of running these vehicles in an environment hostile to human life has been mitigated pretty well.
I was imagining more of a bracer sort of thing. Bigger wheels, self-balancing, straps to your shin.

Better ankle support since these things are going to be powered. Not built-in to your shoes, so you don't need to replace it as often and you can stash it if for some reason you don't want to look like a weirdo. Bigger wheels, probably just one wheel per foot, probably self-balancing. Jump and flick to deploy or stow, large single-wheel moves to the back of your leg when stowed.

But yes, I suppose like heelys.
Curious, isn't it? Humans rely on auditory information to enhance situational awareness so you'd think that would factor into the design of a machine that needs as much situational awareness as possible.

For example, emergency response vehicles announce their arrival and direction often long before any visual contact is made. How will deaf autonomous cars recognize incoming emergency responders if the view is obstructed? Will they pull into the intersection just as a Fire Engine is running the red light?

Auditory input was deemed important enough that California even made it illegal to "wear a headset covering, earplugs in, or earphones covering, resting on, or inserted in, both ears" while driving just last year. [0] I suspect other jurisdictions have/will follow(ed) suit.

Oh my mistake, it was actually I who misread the first comment.

Regardless, I don't think a screen tap logger would be necessary in many cases, since you could just open the keyboard on the phone and manually check the bounding boxes for each key.

Making this work on N phones would be more difficult, but not unfeasible. You'd probably just need to know a few things about the phone (resolution, screen size), and it wouldn't be hard to find that information.

Would be especially easy to just target the limited iPhone line.
Impressive work on reverse engineering this.

Am I correct in assuming that since this backdoor chip has access to all of the peripheral I/O that it could even be used on a device with onboard wireless in "power off" mode, which is usually some kind of low-level sleep? So a compromise of this subsystem (or intentional backdoor) would allow one to take control of even a device that is "off". Given the trend to non-removable batteries, it might actually be impossible to prevent such an attack without physically destroying a laptop.

It always astounds me that growing the number of employees is one of the key metrics of "growth" startups looks for. As if an unprofitable company with 500 employees is somehow more prestigious than a profitable one with 50. Perhaps it's pressure from VCs to chase market share over profits, founder ego, or something else entirely, but it's always struck me as a troubling trend in the startup world. I recall (several years ago) looking up how many employees worked at Twitter and seeing it was over 900 and thinking, "What in god's name are those 900 people doing all day?"
Nope. That was always an empty marketing slogan.

> Is there some social contract that all people are entered into with Facebook?

They have written community rules (don't know the exact name) that members are expected to comply with.

> What large portion of the internet do they "govern"?

The Facebook website (duh). Which, for a surprising amount of people, is literally "the internet" (or at least the part of it that they most interact with).

> As best as I can tell you're arguing that any sufficiently large entity is essentially a government.

No. For instance, Toyota is not a government because it does not set rules under which I can use their cars. Facebook does set rules under which I can use their platform, and it enforces them (which is the entire point of the submission). Setting rules and enforcing them is governance.

In fact, every moderator on any public forum is in the governance business. Since Facebook is so large, I find it reasonable to liken it to a government in terms of influence of its governance.

It works really well when it's the person right in front of you, because you can see that they aren't paying attention. Put a few cars between you and them, and all of a sudden you don't really know the reason they aren't moving and there is a significant delay before you can infer that they aren't paying attention. It would be so much better for their own car to recognize that they are in la la land and remind them asap.

Out of curiosity I did a little benchmark of this rather convoluted but well written 1892 review against a limited sample of 2017 theater reviews. All from The Guardian.

Some of my findings:

- Recent reviews are < 2000 chars long, versus 5856 chars in the posted article.
- Recent reviews are 22 words per sentence long on average, versus 28 words/sentence avg in the article.
- Recent reviews have 62% unique words, against 39% uniqueness in the posted article.

If we compared news articles instead of reviews, I bet the difference would probably be more remarkable.
