Legible text that you can read without squinting and tracked keyboards will be the floodgate moment I think. I'd really like to see how an IDE can evolve in VR space, especially with collaborate features. It could probably make online offices a regular occurrence.
Leftover customs from agricultural society, that have become subconscious moralistic norms. If you sleep the daylight hours away on the farm, you will get less productive work done. After ten generations of this, there will be unspoken and unconscious rules about what sort of sleep schedules are acceptable. These don't go away by themselves.
Saturn V and Apollo were designed for a very specific purpose. And so the CSM could only sustain the crew for the trip to the moon. The 310k lbs payload did not include the CSM and LEM. In theory the Saturn V booster could haul up a BFS style ship if such a thing existed.
One more optimistic way to look at it is using VR it'll make the "boring training videos" much more engaging. I.e. I can think of that annoying video on plane which I hate to listen to, but with a VR where I'd actually have to open that door and jump in it'd be a much more engaging experience.
But evolution happens whether or not the creatures in question understand evolution or even heredity. (In fact, if they know nothing about it, that makes it easier for evolution to do its thing without interference.) The legendary "shape of the human penis designed to pull out the sperm of other men who have recently had sex with the same woman", if it worked, would do very well evolutionarily in the first kind of culture you describe. Likewise, if teenagers being awake at odd hours does cause them to have sex and reproduce more often, then (assuming the tribe will take care of the children) the genes that cause them to do this will be selected for, whether or not the teenagers or the adults realize it.
Present global ad spend is on the order of $600 billion, distributed very roughly across the 1 billion wealthiest inhabitants of the world, or approximately the inhabitants of wealthy industrial nations. This works out to roughly $100 per person per year, or about $8.33/mo.

Allocating this as a tax would more than replace all present spending on authors, screenwriters, journalists, and musicians.
If the frame rate is high (90+) and the shadows are perspectively correct to reality (almost never), then you ought to be fine.

Let's start some controversy.

I think JSX is popular because of historical reasons. Not the history of JSX, but the Web in general, specifically about HTML being the primary API to build web interfaces since the early days. Everyone feels at home with HTML because of this. We all started with it and it is unquestionable for many.

DOM is the second way to build a web interface. But nobody in their right mind would prefer DOM over HTML as long as HTML is sufficient for the task at hand.

The advent of stuff like Hyperscript and virtual DOMs of today introduced a new alternative to HTML and DOM: Now we can build our interfaces using simple data structures (POJOs). This was already possible from the beginning, but the interactivity requirements of the modern application forced us to invent the "UI as a function of the state" paradigm and this approach became mainstream after that (AFAIK).

But wait... Isn't HTML a data structure as well? Not sure. It clearly started as some kind of DSL for building web interfaces. Then XML is invented and HTML was declared as being an extension of XML; thus some kind of data structure (roughly). Then it got complicated. Today I have no idea about what HTML is.

This is the first part of the story.

The second part is about RPC. This one is short. XML used to be everywhere until the advent of JSON. Suddenly everybody started to embrace JSON and hate XML; for several reasons most of which are reasonable.

The question is....

Why isn't the same thing happening with user interfaces? HTML is a subset of XML (or something like that), and the syntax proposed in this article is clearly JSON. Why is everybody embracing JSX like crazy. Do they not find it extremely ugly, as XML is, compared to a POJO?

Is HTML really a better way to represent user interfaces than a solution such as the one presented in this article?

It may be hard to answer as we are all biased in favor of HTML.

It makes sense for the order to be older-younger, because high school has a longer day than elementary school, so pushing their start time to after the elementary school will make it so the elementary kids are out at noon or just after and the high school kids won't be done until dinner time. Symmetrical makes it easier for everyone's schedule.

I've skipped business trips to Europe and the East Coast before because jetlag is completely brutal for me.

And it takes all those tricks for me just to maintain a 24 hour sleep cycle. What I'd like to be able to do is what I did in college and shift my sleep schedule forward an hour or two every day. Instead I have a sleep mask, I start prepping for bed at least an hour early, I take melatonin, I make sure not to eat at night, and I lie down in bed with the sleep mask on for at least 20-30 minutes and listen to programs that help me to relax. Then it takes me 20-30 minutes after I really decide to go to sleep in order to go to sleep.

And right before bedtime is when I'm most alert. Even if I stay up all night, at about 9:30pm I won't be able to sleep.

What is really bad is when I'm seriously sleep depped and I get to sleep at say 7:30 or so, and I can easily wake up after 2-3 hours and then be stuck awake until >3am in the morning.

So I use every single trick in the book and then can just barely manage to stick to what the rest of society thinks is normal and its a constant fight.
I think it was mostly aliasing-related, and that’s why I mentioned “tell which bytes point at which”. Managing C today is like managing that girlfriend who doesn’t say anything straight and avoids direct conversations. I’m not against optimizations, I’m against compiler pretending to be smarter than average me and spoiling our relationship when I only have basic demands.

If not that, I’m also curious.
Come on, I hate PC bullying myself but I think this case is a little different. Linus has historically been very blunt and just outright mean to people that have made mistakes. Since he is the leader, everyone else thinks it's acceptable and tolerable. He recognizes a lack of empathy and is trying to fix it.

This isn't really comparable to the recent Redis development, for example, where the developer had no history of abuse but was attacked anyway for not jumping at the suggestion to "correct" terminology that has just very recently fallen out of fashion.
I think you’re missing the point. At least I do resync to new locations. Just not the way you think.

I used to travel from London to the Bay Area for work with some regulatity. The first few days were amazing, because the combination of westwards jet lag plus night owl meant that I was getting to the office nice and early every day. As the jet lag went away, and I started to acclimate to the timezone, it usually took me less than a week to be back to a night owl routine, even without the usual stimuli.
Reminds me of the one hilarious thing about the USSR and when you look into their histories. They were basically exactly as uptight as the US despite lack of any religious motivations, convinced that the west was out to corrupt the youth just as the US was convinced the same about teenagers. They abhorred homosexuality despite a lack of religious basis for it and no real costs - it would save the state money to have their 'confirmed bachelor's living together openly.

Really it is an authoritarianism thing over any other professed values. As generations of teenagers have told anyone who will listen what they really can't tolerate is anyone openly deviating from the norms - not as a result of any actual harm but because they fear and hate anyone who questions them. A non-authoritaran system doesn't give a fuck about trivial things and has a live and let live attitude.
Great point but put on your helmet. Here comes the right wing comment avalanche.

>doesn't make that much sense commercially but it actually could make a lot of sense in a military environment

That's very interesting, what were his reasons ? I can see how the price reduction of reusable stages is much more attractive to commercial launches, whereas military launches are much less price sensitive. Military launches could benefit from the mass launch (dozens to hundreds of payloads in a critical week) capability that a dozen reusable launchers give you.
“The 310k lbs payload did not include the CSM and LEM.”

Are you saying the Saturn V was able to lift 310k lbs plus the CSM and LEM? I’m pretty sure that not true.

Saturn V was a general purpose rocket. It wasn’t tied to Apollo, as evidenced by Skylab. It just worked out that nobody found a cost-effective use for it beyond Apollo and Skylab.
Social networks versus content networks
It's highly unlikely that such an initiative would ever result in a favorable outcome for the person being defamed. The hoops you have to jump through make sure of that. You have to sue Wikimedia to find out who was the editor, you have to be able to enforce that court order in the editor's country, you have to prove the defamation and possible damages incurred. And if they were quoting and interpreting other articles available at the time you're out of luck. You'll kick the ball around forever. Or as long as your money lasts.

The reasons why Wikipedia isn't implementing any strong mechanisms and processes to avoid or at least to quickly correct these issues are that it's profitable to play the "pay to write anything you want" game and that it's impossible for them to be found responsible. Wikimedia will always be protected by laws like the Communications Decency Act:

> operators of Internet services are not to be construed as publishers (and thus not legally liable for the words of third parties who use their services).

There are people who's Wiki page mentioned them as being suspects of pedophilia, murder, etc. for months and still nobody was found responsible for it. You should see what kind of effort is involved in taking down a page even when it runs afoul of Wikipedia's own rules, let alone litigate.
That's because that demo is using SVG for graphics and hence updating 300+ DOM elements every frame will of course start stuttering... Once I've updated that example to use the hdom-canvas support lib (https://github.com/thi-ng/umbrella/blob/master/packages/hdom...) this will be a non-issue. E.g. here's another demo which draws 10k rectangles @ 60fps. Only once I go >25K, I'm starting to loose framerate (MBP 2016):

Why sell zines?
Yes. I lost a mother in law due to that.

She had legit signs of heart disease. Got told repeatedly it was diet. Went out to work and, hard core as she was, powered through a heart attack.

Damage was terminal. She lived a few more years.

Hard core again, she got tired of being zapped back to life, asked them to turn it off. I had to intervene and force it.

She lived another blissful month.

Through the whole thing, it was, "woman, you know nothing" right and left. I basically became full time patient advocate, and wish I was in that role earlier.

Do you really not grok the difference between writing platform-independent code and writing the platform itself? You don't write for an abstract machine as specified by the standard, you're writing for a very concrete real-world machine in order to implement a part of that abstract machine. Indeed, that's exactly what C was created for in the first place, for writing an OS in something else than assembly!

Well, you're assuming that just because we think it might be better for the kids, we should automatically do it. Everything is a compromise, including school scheduling. In particular, for any households where both parents work, shifting school hours could be a serious burden. Easy for those of us who work in an office with a flexible schedule, or have a stay-at-home mom/dad, but we're in the minority.
Tradition is a form of knowledge, and one that is not so easily reconstituted once it's been destroyed.
There's a surprising history here of which most people are almost wholly ignorant. Robert W. McChesney is among the few scholars who've explored this in depth in the US, see for example:

"The Debate Over Public Policy and the Emergence of Commercial Broadcasting in the United States, 1927-1935"

http://www.thebhc.org/sites/default/files/beh/BEHprint/v021/...

When the BBC was formed in the UK, the concept of allowing media ownership to be in the hands of private corporations was considered unthinkable.

Government funding has its own set of considerations, though in balance it seems generally preferable, most especially if funding and control are separated.
They may still be sensitive from the Nixon incident.

In 1973 some students from Dabney Hovse hung a large "Impeach Nixon" sign on Millikan library (the tallest building on campus).

This upset the founder/President of a major oil company, who cancelled a planned $1 million donation to Caltech.

It also upset the Dabney family, which Dabney Hovse was named for. They disowned it. I'm not quite sure how you disown a house that is named after you, but I'd guess it includes stopping any ongoing charitable giving to the house or the school it is part of.

That "Impeach Nixon" sign was quite unusual for Caltech. Students just really don't have time for such things, because the workload is large and intense. The only known organized act of public protest there before that was in early 1968, when Caltech students went to NBC's studious in Burbank to protest the cancellation of Star Trek.

I'm a non-24 (https://en.wikipedia.org/wiki/Non-24-hour_sleep%E2%80%93wake...). I consistently drift forwards 1-2 hours / day. Nobody believes me when I tell them.

I started seriously tracking my sleep a few months back, and two months ago I started to use "Sleep as Android", which has a neat feature that shows you a graph of the times you are asleep.

This is mine for the past 2 months: https://i.imgur.com/PHohyO6.png

I was myself shocked by how consistent the drift is.

Anyway all that to say, I often experienced pretty much what that excerpt describes. Very frustrating.
The secret life of teen scooter outlaws
I don't think they're talking about the vagus nerve, but rather some neuron-like components of enteroendocrine cells in the gut that allow a faster connection between those enteroendocrine cells and the brain (which of course travels through the vagus nerve).

> Enteroendocrine cells, which stud the lining of the gut and produce hormones that spur digestion and suppress hunger, had footlike protrusions that resemble the synapses neurons use to communicate with each other. Bohórquez knew the enteroendocrine cells could send hormonal messages to the central nervous system, but he also wondered whether they could “talk” to the brain using electrical signals, the way that neurons do. If so, they would have to send the signals through the vagus nerve, which travels from the gut to the brain stem.

In other words, just because the vagus nerve innervates the small intestines on the macroscopic scale does not mean enteroendocrine cells have a complete electrical connection to the brain on the microscopic scale.
The video may have some parts that are slightly more on the left part of the screen and soma parts that are slightly more on the right side of the screen. If you don't look to the correct side, the system may send a small electroshock, make the video longer repeating the important parts until you pay attention, select a longer version of the video where the repetition is not obvious but they keep saying the same thing again or again, or let the system randomly select you for a voluntary group for a new training video tomorrow.

This article is far too focused on the domain of web programming where you almost always propagate the error to the main loop. However, in a large amount of programs you actually are able to handle the error at the call site.

Furthermore, whether an error can be handled or not is a property of the caller, not the callee. If you're writing a public api and don't know your caller then checked exceptions are safer, and callers who just want to propagate the error can still write an api wrapper that rethrows them unchecked.

I do agree that checked exceptions are poorly implemented in Java though. In my dream world checked exceptions would be replaced by Either types which wrap a value or an error and there would be macro-methods for both propagating them and throwing them unchecked. There would also be union types for representing a set of possible named exceptions. Rust is probably the language closest to this.

Finally, if you're writing internal code for something like a web api, then of course you should stay far away from checked exceptions and rethrow them unchecked as early as possible when calling external code.

True. And VR allows new school models with a wildly different cost structure than today's. You don't need a physical building, no physicial equipment and geographic location doesn't matter.

In addition, because VR makes project-based learning [0] more scalable, a teacher's time can be used more efficiently.

These cost-savings can be passed on to the students and the teachers (in the form of higher salaries). All this while improving average the education quality.
