Speaking only for myself, there are two big reasons I never go to 3D shows anymore.

First is that the technology is just plain uncomfortable. The glasses feel bad, and my eyes hurt after a while.

Second is that filmmakers seem to have no clue how stereoscopic depth perception actually works. Objects only have perceptible parallax out to a couple dozen feet. Beyond that, depth is perceived purely by other means. But 3D movies keep applying parallax to objects much farther away. All this does is make them look closer and therefore smaller. The worst example I saw of this was an IMAX film at the Smithsonian about the development of the Boeing 777. There was a scene of a distant 777 in flight which popped the plane out of the screen. The result was that this 100-ton building-sized machine looked like a child's toy.

If the technology can be improved so it doesn't hurt, and if filmmakers can figure out how to use it without it looking utterly stupid, I'll give it another shot. Until then, I'm sticking with 2D.
I went to the IMAX at the zoo in MN and watched Jurassic World in 3D. It was amazing, and actually made me want to see more movies like that. It was much nicer than the standard IMAX.

They had a preview for The Walk and that preview showed the true depth of 3D.
I recall Vietnam managing to survive the US Army despite lacking planes and tanks. Holding land ultimately requires boots on the ground, so unless the government plans to engage in total war against an insurrection (mass bomb American cities), guerrilla will be possible.

It's also highly likely a portion of the army would defect if things get that far, making it less a revolution and more a civil war.
That actully sounds like a great idea. Wonder why it was never considered?
Stereoscopic 3D that requires glasses or separate displays is not interesting. True 3D, e.g., by using phased arrays in the optical spectrum without glasses or separate displays, that will be interesting.

The issues and solutions you list sound super valuable. Do you know if there is a write up about those issues somewhere or did you just learn through blood and sweat?
> You mean it's okay for everyone to struggle to work with JavaScript for years and years trying to come up with an OO system and a module system and trying to just bundle the files for the browser, but it's not okay to spend months on getting intimately acquainted with the language?

You're saying that like those things are a contrast, not two incarnations of the same issue. Safe-and-usable is the holy grail for exactly this reason - right now we have usable-but-unsafe. Javascript isn't a few months to get acquainted: it's a few days to get passable results and a lifetime to get good ones.

So there's a huge need for a better mainstream tool, because the alternative is letting the existing ones endure. That doesn't have to be Rust - there's plenty of space for languages that are hard, but good for key applications like safe browsers. But it has to be something - lecturing people doesn't actually reduce reliance on easy-to-learn, hard-to-secure options.
I really hope they continue offering 3D TVs, especially since 4K offers the option for full 1080p passive 3D to be a possibility. I found a couple TVs that can do it already, but right now they're pretty expensive.

If they actually do fully do away with 3D sets, I'll be looking to nab an older model when they drop in price.
C++ has a pretty steep learning curve, yet people use it.

Many things in tech are tradeoffs. Sometimes the additional tools a language brings to the table are worth the learning curve, sometimes they aren't. There are people in the industry for which FP (or Rust, or whatever) is worth it. For you it isn't. That's life.
They can both sometimes have those problems. Both can lead to the feeling of overstimulation which can lead to the same focus issues. For example, "So much is going on I can't pick which to pay attention to".
I understand. Most developers don't care once they've got their ad impression.

Although I don't assume people would outright buy the game without trying first. Especially from a first time developer. So the free version is a necessity for me.
I think whether you feel you need unsafe when you first come to Rust depends on the angle from which you're coming.

Coming from C/C++, I know that there are structs in memory and can visualize what they look like - surely I can just go and tweak them? (No I can't because either it wasn't safe to do that anyway, or I need to explain to the Rust compiler why it is safe, and that can be quite difficult.)

Coming from something like Java, I (probably) don't think too much about what the underlying structure in memory is, so I'm less likely to try to do this.

Either way, it feels like part of the learning curve is learning the "Rustic" way to do something - in general, you probably shouldn't be reaching for "unsafe" until you know what you're doing! ;)
It's not a gimmick, it increases immersiveness when done right. The problem is the technology isn't quite there and directors haven't been trained in it (and usually don't make the effort) - so it's basically never done right.

3D as we know it is probably never going to happen. Most movies don't gain much from more immersiveness, and the tech may always be clunky. I've seen some VR movies lately, and I predict they will supercede 3d entirely. Whether they'll end up being the next fad is an open question.
Sudo and polkit are so complicated because they solve the wrong problem. The common problem is how do I execute code under a different effective user id. Instead they try to solve a much harder superset: how to securely implement a policy defining who is allowed to execute what under which effective user id in a setuid executable.

There are much simpler solutions without setuid: https://skarnet.org/software/s6/s6-sudo.html.
To each his own, I guess: the lower brightness is actually the main thing I like about 3D. It's occasionally done well enough to add something to the movie. Other than those cases, the only benefit is having not as bright a screen in a dark room.
It most likely wasn't skimmed. 13+ years ago I did some WU carding and it was really hard. I'm sure their security has gotten even better.

They only accepted credit cards online and by phone. They required a ton of information in order to process it, often verifying items from your credit report. To pull it off you had to have a lot of info about the cardholder.
Great write up
No, because 3D never really had "wow this is so much better" appliances, meanwhile (if you don't get motion sickness with VR headset) racing games with VR are so much better and work insanely well.
The likes of IPFS and Freenet work on this principle.
I was completely surprised by how great home 3d is! And I don’t really like 3d in the theatres at all.

Last year I bought a 55” 1080p LG OLED and on a lark, picked up a 3d blu-ray to see how it looked. Jeez, I was totally blown away! So much better than the movie theatre “Real 3D” while using the same passive glasses. A ridiculously beautiful 3d effect that was easy on the eyes. Just amazing. I started to stockpile whats left of the 3d blu-rays being produced. Thankfully, the 3d blu-ray editions tend to have all of the 2d versions as well, so it’s not the end of the world.

Favorite 3d blu-rays: Avatar (omg, just incredible), Inside Out (hankies required). 3d animated movies are the best.

I will go over and add my name to the petition. Home 3d is great.

HDR seems like another TV sales gimmick. Isn't HDR more about capturing the image with a lot of range rather than displaying it as such?

Color support does seem to matter in a side by side comparison for me. My MacBook pro colors "pop" a whole lot more than my gaming monitor's colors do. When I don't have them right next to each other, however, I hardly notice. It's hard to tell if it's the color (I think it is) or the resolution.
My wife and I were on a date and I thought watching the first Hobbit movie in 3D would be a fun, impromptu thing to do after dinner.

She loved the experience, so I sat there for three hours watching a blurry movie because the 3D glasses were awful and causing pain.

Never again.
> You can touch-type the function keys without looking down, because they are all grouped in four.

This is true. The new Fkeys are not grouped.

> The arrow keys are proper sized buttons (even the macbook has it wrong).

This is false, look at the linked image[1] and tell me that the arrow keys are different on the new keyboard.

> There is a slight curvature on each key's surface that makes it easy for the finger to feel the borders.

This is also false. The chicklet keys are slightly concave and the island layout makes it extremely easy to feel the borders of each key.

> All of these are missing in the new keyboards.

Again, this is false.

> This chiclet design is the worst thing to happen for the thinkpads.

This is subjective. I have both keyboards, and I like the new style better. I'm a linux user and I use vim. I've probably pressed the Fkeys 10s of times in the years I've owned either laptop. The entire row could be removed and I probably wouldn't even notice.

It's fine if you don't like the new keyboard, but the reasons you are giving are simply not true.

I saw The Martian in 3D, and I thought the 3D added value in the shots of the Martian desert.

Then they had indoor shots that used depth of field, while still using some 3D effects and totally ruined it for me.

The whole point of 3D is you can choose what to focus on! The moment you ditch that the effect is ruined.
Yep! Watts' novels are how I first heard about Portia. I can't wait for the third in the trilogy.

In general, I love a good novel with a bibliography.
Well, I love 3D movies but I've never been interested in a 3D TV, I think because watching movies in a theater and at home are very different experiences. If I always watched TV sitting up straight without leaving my seat, I'd probably buy a 3D TV.

I don't really understand how enjoyment is a moot point. Enjoyment is pretty much all that matters for a consumer entertainment product.
Accurate reproduction has always been seen as a negative among a certain set of people used to what came before. Other examples include higher framerates for movies, digital photography, and compact discs.

If you live with a technology for long enough, you can start to see its flaws as advantages instead.
In what way is "class" not identity politics? Is it just identity politics that you identify with?

Junior positions I think not, especially as a Product Manager (well depending the size of your structure) is supposed to have lots of contacts, all the time, even when he's overloaded with tasks.

I know I wasn't in the same role, just mentionning what I witnessed regarding Product Managers where I worked in the past..
Having been a Product Owner for a couple of years in a 10k+ employees international company, just to name a few guys you need to meet regularly for the sake of your product, from makers to users :

Developpers teams, QA teams, Product Support Teams, Marketing teams, Finance teams, Sales teams (Global, Regional), Delivery teams (Global, Regional), Training teams (See a trend here?), Customers (from time to time, not counting support escalations).

Out of these exchanges you get your product needs and issues which you need to rationalise, plan and translate into features and fixes, plan a macro and micro roadmap including slightly-expected hotfixes, service packs, long term roadmap (to give your customers a sense of what's coming - up to 5y forecast sometimes), adding also various compliance rules on top of this (depending the market) and a frosting made of turn over rates plus international culture complexity.

Of course what I'm mentionning is not the whole world, but as far as I can tell it's a good picture of what you can expect from someone doing decent international product management.

Therefore, a junior Product Manager would be pretty much difficult to pull, unless you're hiring people who had the opportunity to cross the intellectual and business bridges (consumer/producer/user/support) a couple of times in their carreer (imagine yourself drafting your new product roadmap while travelling a plane to show up on site on a Friday in a customer's office to defend your product against a missing/crippling feature and try to propose a mitigation plan with the help of the local delivery team).

A Product Manager is in a sense a one man band, half Project Manager, half Architect, Salesman, Support Manager, Training manager, end user, customer, etc.

So, Junior without someone to back you up, I don't think so.
Junior without having some experience of the Trenches, hardly, as you can easily be reckless toward the teams mentionned above and also miss some red flags ("ivory tower" syndrome).

If you find such an opportunity, be wary on the context and the expected work. This role can be more stressing and alienating than being a Project Manager because you are supposed to represent a Product in any aspect of it.
> programming in Rust became much easier

Much easier than what? Writing C? I believe you.

I agree with you about maintenance, and I agree that there are two separate issues, but still, extra proof must invariably carry some extra mental burden. There are no free proofs just as there are no free prime factors. This isn't a philosophical issue, but a computational one. But it's also true that the mental burden might offset a different sort of mental burden. So whether there is additional work or not is unclear, but I think it's pretty clear that the nature of the work is different.
Lisps can do anything other general purpose language can accomplish. People still overwhelmingly choose other languages.

I keep stressing "it's not about the money..." and as days drag on, I keep spending several hours a day on building a site for a "client" without pay.

I work at a restaurant washing plates, prep cook, fryer. But I'm also a freelance full stack developer. But I'm also not using things like Laravel, Angular, Heroku, being proficient, competent developer.

So I'm in the process of building this cloud-based photo-oriented web application and I keep doing more and more work on it. I agreed to deliver part of the page for $100.00, and I've been working on this since beginning of December. I've often spent days where I almost put in 12 hours of work.

"I feel bad" but also I've been paid $75.00 for doing CSS media-query corrections on a site.

Now I feel like I'm the bad guy for expressing my concerns. I am the bad guy because I agreed to deliver this site for $100.00 and I'm complaining about how much time I'm spending but the features keep adding on, like "Oh now we've got to optimize this."

Now that I've spoken my mind it's awkward. Jesus it's pathetic. My other client on the other hand who's paid me over $600.00 for modifying their CMS building PHP scrapers, and modifying their layout, etc... They too have slowed down in paying me. I just do things. I feel bad to ask to get paid.

The cloud client is based in a "third world country" where their currency conversion to mine is 50:1 so I am expensive to them despite me being worth $15.00/hr ha. It's pathetic. I don't think I can be a business man with this mindset.
Curious. Where did you even get that from?
Kid's movies that touch on adult subjects, but at a simplistic level that apes at understanding... Like Marry Poppins and Women's suffrage. It's in books too, like The Whipping Boy, where oppression by the nobles is a whimsical journey of discovery. How to introduce children to adult concepts through art, without creating a false narrative that presents over-simplified half truths? Not sure what the answer there is, but The Sound of Music definitely falls into that... von-trap (couldn't resist the pun).

I'm not a PM, but I partner closely with them and also interview them. At LinkedIn, most of our PMs have both an MBA and a technical background of some sort. Many have also started companies of their own in the past.

We actually DO have junior PM roles -- "Associate Product Manager" positions that are designed to ease people into the PM path and let them grow into the full skill set.

Key skills are ruthless prioritization (project manager skills) plus product vision. A great PM can look at a bunch of information (our current assets, market trends, internal and external data, etc), develop a vision of what our future should look like, convert it into a practical roadmap to get us there, and herd all the cats to actually make it happen.
Landauer's principle would come into effect if you had a theoretical "Computorium" material that could perfectly turn energy into computation. Then the computation you could produce per volume of space would be limited by it.

Our brains are (very) far from being the perfect computing material (so are our chips).

The theoretical minimum is only useful here to show that our brains cannot do free work. (Irreversible) computation always
has a cost.

The 20 Watts are the important number. Our brains have a certain energy budget and have to perform within that constrain.
I used a Bullet Journal for a couple months a few years ago. I ended up moving away from it, for a couple reasons:

- It didn't suit my note-taking instincts: most things that I think are worthy of writing down are either much longer than one sentence (notes from a meeting, say) or much more numerous such that they would drown out the todos and events.

- It was difficult to generate a view of "okay, what needs to be done today?"

- It felt frustratingly analog: things like running monthly migrations and building up a table of contents was one of those moments where I was just like Ugh, can't I have an app do this?

These are largely quibbles with my own personal habits and tendencies, rather than flaws with the system itself. I'm happy with my replacement approach -- Todoist with daily Bullet Journal-esque notes that get migrated at the end of the day -- but it's still lacking with regards to retrospective.

That being said, Bullet Journals were the first step in getting me to seriously consider how I retain information and organize my tasks, so I'm forever grateful of them for that!
I've started to think there are only two ways to impact government policy:

- Have hundreds of millions or billions to spend on lobbying and otherwise playing the regulatory capture game

- Create a reasonable sized public following of single-issue voters

As others have said, this is a battle that comes up over and over and over. Unless there are voters willing to go nuclear (cross party lines, support insurgent challenges to incumbents) these rights are precarious.
I found this quote from Dr. Pratt particularly salient, "But fundamentally a thing your readers should know is that this really comes down to testing. Deep learning is wonderful, but deep learning doesn’t guarantee that over the entire space of possible inputs, the behavior will be correct. Ensuring that that’s true is very, very hard to do."
I would cautiously agree. The overall quality of VR - the headsets, the displays, the content - is just not good enough on current-gen devices (especially considering the price).

Unlike 3D TVs, VR might be here to stay for the enthusiast market but I don't see it becoming a mass market must-have gadget for every household.

And because the current generation is so underwhelming and overhyped, there might be a 5-10 year period of relative silence before the next-next generation comes out - hopefully with much improved quality as the technology improves.

But the next year will tell... and it's up to the content side. If there will be a mega hit game, movie,other entertainment experience or even a serious application coming out I might be wrong.
> Lock-in doesn't cause you to be able to 'squeeze performance' out of the hardware.

Let's assume GPU X supports some feature that GPU Y does not. Then you either use an (say OpenGL or Vulkan) extension to use it to squeeze out performance (lock-in) or you eschew the lock-in, don't use the feature and ignore the performance advantage. Now multiply this with lots of features and also consider that the graphic APIs of consoles offer some rather unique features that don't map directly to, say, DirectX11 or OpenGL.
From personal experience, it's not that bad. C++ is "Java plus you need to worry about these other things", and it pays off in power and speed. They're not so similar in safety/scope terms, but the structure and design have enough in common that you get plenty of spare brainpower to worry about managing C++.

It was, for instance, a way more natural transition than "Java and C++ to OCaml". Less educational, but as usual that trades against easy.

I'll check it out. Difficulty setting is a great idea. I was also thinking about adding a practice section where you can select the operations you want as well as the types of numbers.

The original comment seems to be saying that VR is a fad because it's similar to 3D TV. You're saying that VR is similar to 3D TV because it's also a fad. You may well be correct, but that can't be used to support the original comment, since it would be circular reasoning.
There's also Bitcoin, which costs significantly less than all these money transfer services, doesn't require disclosing tons of personal info to use, and is decentralized.
The HoloLens could make it because it doesn't lock people into their own display. However it's still a long way from being ready for prime time. Two big problems:

1) a very narrow field of vision, about the same my 15.6" laptop screen at the distance I use it. It's very easy to miss virtual objects and having to look for them it's not a great experience compared to the peripheral vision we enjoy in RL.

2) Objects are always transparent so colors are weak. Unfortunately I don't see a way out of this, especially outdoors. There can't be black unless in a dark room.

#1 can be fixed, I don't know about #2.
