The idea that scrolling may be jarring enough to hamper reading fits my experience. When I scroll, it doesn't feel like just my browser has to repaint the whole webpage, but it also feels like my brain has to reconstitute the structure of the page via a kind of inverse-repainting, just so that I can reorient my attention, before I can resume it.

In other words, if I

- have a (semantic) pointer to, say, the last word on a line

- am maintaining just the single last word I read in my short-term memory/register

- scroll and then have to look for the line I was just on before I have reoriented myself

then it feels like I have to do a kind of mechanistic attention-interrupt/syscall that locks my conscious interpretation of the text's meaning until I have returned to the index of the text that I was just at. I guess that also explains why sometimes, when I am simultaneously trying to reflect on the text while scrolling, I am significantly less able to do so fluidly, as if there were some underlying deadlock, and more often than not have to repeatedly attempt finding the next line..

But if you hold a book in your hands, there is much less variation in the 'streamed/online/', structural form of the text. More or less, all that my brain knows it needs to anticipate is page turning. It can figure out how to cancel out my hand movements, background visual information, surroundings, etc. from my conscious experience because that's what we've evolved to be able to suppress from our attention.

Maybe, then, computer file viewing UIs that have page-flipping skeuomorphisms are less attention interrupting, because they would avoid these interruptions being done more than one time per page/pair of pages?

I use a laptop for my CI server. 8 cores and 16gb ram, hides in my basement. Would easily be $400 a month for those specs.
This doesn't really seem to hold much water. For one, the study was done on college undergrads, a non-randomly selected group who have crossed a certain bar for basic comprehension (looks like the researchers are from the U of Maryland, a major university, so you can expect that the students on average will have well above-average reading comprehension compared to the rest of the world).

On top of that, as a former K12 educator, the tools matter far less than the teacher implementing them and the fidelity of execution, very little of which seems to be explored by this study. I don't think digital texts or computers in classrooms are a panacea for what ails our classrooms or that digitizing textbooks is even that exciting when it comes to EdTech -- it's just taking a 19th century tool and digitizing it. This study, however, does not effectively demonstrate that either medium is better than the other, but the Ed world is in desperate need of strong research in that regard, specifically in the efficacy of EdTech in the classroom.
I'm still awaiting for the update myself or to hear from others on what kind of battery drain to expect from 12 hours of use. Super excited for this feature though.
I don't think row polymorphism is what the OP asked for. They might be what the OP wants, but that's a-whole-nother matter.

If I understood correctly, the OP asked for a “duck type of all values on which a function `f` can be applied”. Alas, OCaml-like object types are glorified function types, not duck types:

(0) The type of an object is the type of its methods.

(1) The type of an object is not the type of its internal state.

Say you have a particular data type like `float list`, and you want to “bless it with a method `f`”, so that you can pass a `float list` to any context that expects an object with a method `f`. This is everyday stuff in duck-typed languages.

Turns out, you can't. The best thing you can do is explicitly construct an object with a method `f`, and whose state happens to be a `float list`. Alas, because the state isn't a part of the object's type, there is no way a user of the object can recover the original `float list`. In fact, no user of the object has any way to tell whether the object's internal state is a `float list` or something else altogether.

I much prefer physical textbooks but their bulk presents an issue. It's not fun hauling around one tome per class. I remember back in high school my backpack weighed 30+ lbs.

Last year I bought a 12.9 iPad pro as a textbook replacement. It works great (still miss the physical paper though). It has also greatly reduced the amount of weight on my shoulders during my bike commute to and from school. Nowadays I only carry my laptop and my tablet in my backpack.

Goodnotes can handle huge PDFs and enables me to write on and highlight the text. Voice Dream Reader is a great app to help slog through boring reading (Salli is the best voice I've found so far for scientific lit). I don't use Kindle-like ebooks for textbooks. Similar to what u/acconrad said, I need to be able to write on the text.

With all that in mind, my iPad pro is a designated READING device. I have notifications aggressively disabled for pretty much every app. No Facebook social media apps allowed. I won't/can't even log into Facebook on my web browser (someone else manages my password).
A web search is not meant to count as research, it is the equivalent of a library catalogue search. You're meant to follow the links and find out what is written on the subject. It is the internet equivalent of a literature study and as such a form or research. The assumption here is that the reader is intelligent enough to be able to separate authoritative sources from hearsay and agenda-based publications.

By the way, using terms like "no reputable journalist" is called "Master suppression technique" or "domination technique" [1]. It is detrimental to having a fact-based discussion and generally seen as a cop-out for those who don't have real arguments to add to the discussion.

And that's why it was a company I was talking to, and not a company that I worked for. But, I recognize that I was in a fortunate position, and I did not currently need a job then. Had I been in a less fortunate position, things could be different.
If they've minimised the boom perhaps it's genius.
I'm not really following you.

Rationality and adaptive markets hypothesis are not mutually exclusive. Moreover you seem to be attacking a strawman of what economists mean when they use the term, "rational actor". Economists do not actually assume everything is perfect or that the market is perfectly efficient - not even Fama postulates that. Rational behavior is an approximation, and economists are such approximations do not perfectly model the market. That doesn't mean they don't have any predictive ability or empiricism.

I also didn't see any changes suggested by the article - there doesn't seem to be anything in it that's at all prescriptive; how are you drawing a connection to HFT?
This is a foolish and idealistic stance.

Especially with all the factors to consider (neighbors, location, salary, relativity to peers, etc.)
Bernie Sanders was swept under the rug for the "benefit" of Hillary Clinton. Trump did nothing in comparison, he simply reaped the fruits of that own goal. Which of course people swiftly pretended didn't happen to complain about Trump, being shocked constantly like some looping meme gif.

Instead of using 4 years to clean one's own house, they're working harder to make it dirtier. I say "they" because I don't do the liberal/Democrat/conservative/Republican thing and am not American. So, I can tell you what the result of that will be: even worse stuff. Remember how Obama promised hope & change and removed nothing of what Bush created? But who cared, he wasn't the grating thing Bush was, and congress blocked him, and la di blah. Same shit, same day. As long as it is like this, it will always be the same lame day. Everybody has their scapegoats, nobody executes their "own".

This is how one knows publicly funded research is fundamentally broken. Sloppy research is fueled by the push to publish, which is fueled by too many people climbing over each other for too few spots.
As a "lowly CSS developer", I'm actually okay with this. w3.org specs are meant for browser developers, MDN docs (supposedly) are meant for web developers.
Progressives are at war with everyone rather equally; so I don't see the utility in insisting on a unidimensional axis. They claim to be opposed to white nationalists specifically, but then they go on to categorize literally everything to their right (including liberalism) as white supremacy. And I say "equally" because progressives spend more time criticizing moderates than the extreme right.

Further, I question the sincerity of the progressive commitment to equality, since the mob comes after anyone who points to data that don't support their apocalyptic narrative.
Yeah, I'm going to go with low rent, low wages and low willingness to pay.
sleeping in a car is news?

lol you fucking idiots.
I drive a volvo XC70 (the outdorsy station wagon) and its incredible for sleeping in. I've probably logged 8ish days in the past year or so. The best benefit is that most campgrounds in places like Yosemite are limited in capacity and you can't really plop a tent down anywhere, but the parks service and land management folks have not seemed to be bothered by my parking wherever I want and sleeping for the night. I highly recommend it to avid campers.
I'm sure I'll like his book, but this article is shallow to the point of being trite. Any recommendation for a better intro?
They also tended to use usergroup permissions to restrict new users from posting URLs before they'd been a member for a certain amount of time (or posted a certain amount of messages) or had early posts subject to moderator approval if a link was included.

Never saw a lot of sites using 'innocent' URLs to sneak porn onto random internet forums in the way you describe, cause said sites would simply treat any spammed link as suspicious regardless of what it claimed to be.
The Swedish SAAB 900 models were _great_ for this, in my experience.

California has something similar for “state employees” which include university professors and high school teachers among others. It’s called Transparent California.
$63 billion to produce 400 companies seems like a statistic someone would cite if they wanted to argue against this funding. That is roughly $150 million per each new company. That seems like a very high number, particularly when their is no qualifier as to the success of any of these companies.
>Overheating in cars is the leading cause of traumatic death for K9 units.

Sounds like handler misconduct to me, but hey -- it's easier to blame the vehicle!

Too bad civillians don't have the same luxury of blaming the equipment.[0][1][2]

It's ridiculous -- and eye-opening -- that k9 units get that kind of treatment. I was always under the misconception (which is probably purposely portrayed in the media) that the dogs were treated as partners -- not tools. I guess that was too hopeful on my part.

>I've already had to have a meeting with several postdocs who said something similar to I don't trust 90% of published articles.

GOOD. They should feel that way. Science is in a state of crisis and that 90% number is an accurate reflection of reality. In the study mentioned below 90% of landmark cancer research papers could not be reproduced. Someone will surely chime in that their own favorite branch of science is better, but better than 90% failure is a really low bar.

There's also the issue of comparing research to other forms of production; research is different.

Research isn't something that is easy to measure "profit" in. Rather, research is a lot more like the exploration of the unknown or sparsely known.

Discovery of a new process or physical law of nature could lead to more benefit than even a gold rush. Maybe we figure out how to actually make fusion work at small scale (economically). Maybe a new way of looking at atomic interactions allows for the creation of entirely new classes of devices across many categories; getting us closer to actual science fiction toys.

Without research, we probably won't get there, and it'll sure take a lot longer if we aren't trying.

Research can also be compared to efforts to break 'enemy messages' during a WWII. In some ways success was possible and that made victory much easier to achieve. In other ways it was either harder or didn't pan out; that didn't mean it was impossible, it just meant that it wasn't within reach of the general level of technology that existed at the time. The tools of today make those old techniques prone to even brute forcing, which means that problems that fail conventional searches today MAY be unlocked by future advances in other fields.

You never know if you don't try to look.
OTOH, even modern Jeeps are fine to wash out with a hose or leave in the rain. It seems weird, but there is even a drain plug under the carpet on each side. The only two components to watch out for are the clockspring in the steering wheel (which lasts about 50 miles on a Wrangler anyway) as well as whatever radio head unit came with the trim. Nothing else seems to care. It's awesome.

I've inadvertently driven mine with the top off in a persistent downpour, where I learned that (a) windshield wipers don't work on the inside, (b) wearing glasses presents an annoying set of challenges, (c) expect an especially wet left butt cheek from the tire flinging water past the fender at speed, and (d) other drivers will take pictures at traffic lights. Fun, though. Radio still worked and everything. Just drained it when I got home and let it dry in the sun. I bet your Element would do better than you think.
Look, let's talk about replacing word2vec because it's old and not that good on its own. Everyone making word vectors, including this article, compares them to word2vec as a baseline because beating word2vec on evaluations is so easy. It's from 2013 and machine learning moves fast these days.

You can replace pre-trained word2vec in 12 languages (with aligned vectors!) with ConceptNet Numberbatch [1]. You can be sure it's better because of the SemEval 2017 results where it came out on top in 4 out of 5 languages and 15 out of 15 aligned language pairs [2]. (You will not find word2vec in this evaluation because it would have done poorly.)

If you want to bring your own corpus, at least update your training method to something like fastText [3], though I recommend looking at how to improve it using ConceptNet anyway, because distributional semantics alone will not get you to the state of the art.

Also: what pre-built word2vec are you using that actually contains valid word associations in many languages? Something trained on just Wikipedia? Al-Rfou's Polyglot? Have you ever actually tested it?

Your neighbour might not be using said truck right now, but it's availablity for use instantly is in itself valuable. Ownership gives you that. If it was shared, then you lose the instant availablity.

Unless the automation creates free trucks for all to use, you scenario can't really come to pass.
>we don't hesitate twice when buying the cheap stuff

When things like gas and international trade are heavily subsidized (either directly or indirectly using preferential trade agreements) we create a world where this is the norm. When this is the local maxima of capital growth in these areas, this is where capital will invest.

Quite a lot presumably. Ever since the idea of a media started, there have been people trying to hoax it for whatever reason or not:

http://hoaxes.org/weblog/categories/category/Journalism

If a story is mainstream enough (or remotely political), hoaxes will probably get identified at some point or another. If it's in a specialist subject area? Forget it. Who knows how much questionable stuff slips through when neither the journalist nor their audience know what's plausible and what isn't?
There is at least one very good solution.

Significantly increasing the earned income tax credit.

Warren Buffett has been pushing this for a long time as a superior alternative to increasing the minimum wage. We can push to $15 / hour equivalent without punishing businesses that can't afford the minimum wage at that level. Few people on either side are listening to him however; Democrats in Congress are mindlessly latched onto the minimum wage as the only solution, and Republicans dislike expanding such benefits in general. It can be done without changing much about how the system works and it would immediately begin boosting the standard of living for the bottom 1/2 of workers. The EITC is superior to the universal basic income, as it doesn't needlessly give money to the well-off (ie it isn't inherently regressive) and the US could actually implement a higher and broader EITC system immediately.

Python's official docs do a good job with this approach too, I think. The Python Language Reference is relatively easy to read for a lay-man when that's necessary, and includes the formal logic of the spec in little call-out boxes -- but it's also accompanied by the Python Tutorial, which manages to cover nearly everything while making no attempt to get into every edge-case and obscure method, keeping it focused and readable. It's a great learning tool to get up to near-proficiency, and then the Reference is there for all those little "but I wonder what happens when..." questions.

The next step I'd like to see is for them to prohibit asking where you went to college. You still need to show credentials, but if you went to an accredited 4-year institution and got a BS in, say, chemistry, you would say you had an accredited BS in chemistry, and there would be a gov't database against which that claim could be checked. Someone who couldn't afford the tuition at a ritzy private school but still completed the same requirements for a BS in chemistry from an accredited state school would have the same access to jobs requiring an accredited BS in chemistry.

The next step after that would be for accreditation to be made more flexible, accommodating combinations of work-study, self-study, community college, private lab classes, and standardized testing to qualify a person for an accredited degree without having attended a traditional university at all.

Competition for admission to expensive, elite schools that apparently don't teach any better but simply pick the applicants who have already made themselves elite and charge them exorbitant fees to grant a brand-name credential which then boosts the value of the brand itself is distorting actual EDUCATION beyond all recognition.

The sooner employers have to judge applicant quality by means other than perceived eliteness of their school, the more diverse the paths to employment success can become, which ought to be a goal of both the left and the right politically.
I think all the questions you ask about Chomsky's methods and arguments Manufacturing Consent are reasonable concerns, and nearly every one of them is addressed in the book. The manipulation he found is nowhere near comparable to what you'd expect from random chance.

As for Waxman, I make no claim that she had evidence equivalent to what the current reporters had, nor does she make that claim. In fact, I claimed just the opposite: if the evidence had been that substantial, they would've had no choice but to run it. Besides, the only disincentive to do so — losing Weinstein's company's advertising dollars — would've been nullified by Weinstein's impending doom and loss of control over how that budget is spent, anyway.

We can speculate as to just how solid her piece was, but it never ran. She claims to have "had evidence of a payoff," and also claims that she was told directly why the story was killed. So you can say you don't believe her, and I don't fault you for that, but her reasoning is not unsound. And again, this is just a red herring.
maybe the screen is secondary, on a computer it is way too easy to get distracted especially for young learners comparing to a real paper-format book?
