Maybe also due to Amazon’s tightlipped PR policy, it is not uncommon to read in comments about some article related to amazon such as this one accusations about systematically increasing and even user-specific “dynamically adjusting” prices supposedly to maximize profits.

I don’t work there anymore since a bit, but I am somewhat annoyed by the unsubstantiated confidence with which these claims are made so I’d like to add my anec-data.

First of all, when I left the pricing system had in fact strong incentives in place to _lower_ prices as much as possible (for Amazon sold items. Third party sellers set their own prices.) Amazon would often make (small) losses on many items, especially the ones shown on the home page.

Moreover, there is definitely only a single price for each offer listing (which equals more or less an ASIN and merchant combination). This is evidently the case for 3P sold items, since as a seller you definitely do not have that infamous “auto-gauging” tick box the last time I checked. (And let’s not forget, most of the growth of Amazon comes through third party sellers).
As for Amazon sold items, I invite anyone to actually show evidence that the same offer listing has at the same time a different price for different users/devices, otherwise it is just empty talk.
I'm a far more distracted driver since going automatic
Cuil, magic leap, ... (never forget cuil)
The biggest disadvantage autos still have versus manuals is their larger size and higher parasitic power loss. Americans tend to drive both larger and more powerful cars where the drawbacks of the auto over the manual are pretty much insignificant. Smaller European cars with lower power figures have more difficulty physically fitting the automatic transmission and the power loss from the torque converter is more noticeable.
Mission Motors did one too. See https://www.fastcompany.com/1578451/object-desire-yves-behar...
> Sorry, the point of the article went way past your head.

This is not useful or helpful tone and really does not belong on HN [1]. My comments addressing security and privacy were in response to the current top comment [2].

I fully realize that performance is the goal of the article. What I strongly disagree with is the article's projected viewpoint of the universality of JS being slower.

> despite the best effort of (...) tools that send less JS be default

> Video of a single slow-loading page lands in a visceral way; abstract graphs don’t.

Saying JavaScript is universally slower is as true as saying client side code is always slower. This is obviously not the case. Just imagine if the next CounterStrike game tried to do everything with server side rendering rather than transferring 5GB of game code one time and tiny fractions of that from then on. Obviously the argument is not universal. Costs can be amortized. Code can be cached and intelligently replaced. There are entire industries where nobody would even think to debate that a lot of client side code is the only way to achieve their goals.

I'm not saying everybody does this well, but I'm confident saying that the answer is not going to be universally less JavaScript.

How Blockchain and Smart Contracts Can Improve Customs Control
Cities and freeways are one thing, but I think it's more about suburbia. Stop signs over yields by default, four way stop signs, and roundabouts (circles) being a completely alien concept. These things are kinda fine in an automatic but vastly less comfortable in a manual.
Obama's attacks on Syria and especially Libya created a power vacuum - the incumbent leadership was bad, but in its absence there was a void that anything could move into. If Kaddafi were still running Libya, ISIS wouldn't have been. This is also true in Syria, but perhaps to a lesser degree than Libya, since the vacuum was less hard.
> there's no one entity that regulates the U.S. government

Well, in theory the voters do.
A123 certainly aren't clueless. They're former MIT battery researchers.
Don't forget our good friends ActiveX , ShockWave(whose relationship to Flash I've never been able to determine), and RealPlayer, which had an uncanny ability to be required for every online class assignment I ever had. If you were hapless enough to be running a Linux desktop, as I was, then have fun!

The modern JavaScript experience might be a bloated disaster, but at least it's a cross-platform disaster.
This is an easy argument to make when there's conveniently no way for consumers to decide how they want to pay. Realistically, humans are just lazy about finding decent ways of monetizing their time. I can't say I'll shed any tears if a business relying on ads goes out of business from my ad blocker: they always could have asked me for my cash.
It's because while few students pay the nameplate tuition, for the few that do (high-income and out-of-state students), it brings in a lot of revenue. Thus, there's little incentive to control it, if you can make the net-cost to each student controlled behind the scenes.
Oh beautiful, thanks! I'm really looking forward to it.
"More JS" vs "Less JS" is oversimplified - what are we building here?

- A web app that exists as a tool users log into? This kind of thing would have used to be a desktop app. I'm perfectly fine with a 1-2MB JS bundle. The images and other data you're downloading will soon be much greater than that size. App too big? split it up into modules. Targeting users with 3G or worse connections? Ok, lets look at server-side rendering with a simplified experience. I don't think apps like this are really the problem here. If it is a powerful app I don't mind waiting 5-10 seconds for everything to load, so long as there is a good user experience around loading. These are the kind of apps I build in React and they load fast and feel fast, even on cell connections. Our speed issues and optimizations are generally elsewhere, usually on server-side data fetching. Granted I haven't worked anywhere that has users with flip phones in far-off countries. I would probably choose a different strategy in that case.

- A media-heavy web site that displays content for non-authenticated users? These have tons and tons of tracking JS and other things, not to mention the hated auto-play videos and intrusive ads - I think thats the "CO2" that the author is talking about, but the issue is mostly organizational and economical - these companies are made up of large numbers of people who all need "just one more script", or are getting paid to insert garbage into their page. This is a shame and we can complain about it all we want to but until the economics behind web content improve I don't see that underlying issue getting fixed. This is the problem that AMP is trying to solve. I agree that it shouldn't be proprietary, but you can't expect everyone at a media company to think like an engineer and prioritize site load time over the big bucks in analytics and internet chum, unless it gets too bad. Companies will do what they can get away with, whether its CO2 or JS.
Are you a developer?

I'm sure there are exceptions, but the majority of cases always rules.

There's an entire historical background that explains why most "executives" and founders see programmers, or any employee of any sort, as obedients servs that must compel and be grateful for their jobs.

That "classism" will always be present and act as the strongest force against innovation in that country.

Technology is not a factory and, whenever you try to modularize it in such form, you see mediocre, subpar, results.

There might have some small local companies that are able to challenge the even worse local oligarchs from past generations, but they will never be able to compete at a global level, as you'd expect from a real startup ecosystem.

And if they end up facing an international competitor, they might as well be crushed or acquired by them.

I don't get into a personal attack here, but you may want to experience more in depth some of these places like SF, Israel, Chile, Paris, Berlin to understand these profound cultural differences.
Also, Walmart allows 90-day returns whereas Amazon is typically 30. Walmart now gets most of the business that Amazon used to get from me.
:-) Sure, I agree. We don't know. The comment I was replying to snarkily and passively-aggressively (said it without saying it) assumed he knew for sure (I won't say 'pretended to know'). But it was ironically more certainly what they were accusing the other of, presenting opinion as fact, than what the other was doing, as another commenter already noted.

Also it was hostile in tone. If I, for example, thought you were being too silly, compare writing "I think you're being too silly" with writing "I really hate when people are too silly." It begs the question, and in a hostile way. He wasn't talking to the person but snidely about them.

the opposite is true in the long run. In the finalized scenario, where public transport is cheap, functional, useful and maintainable, or modern cities have been totally rewritten to support pedestrian first, it makes more sense than cars. But between removing cars today, and the day public transport actually reaches such a state, is long and far, and you fuck the car-less over for the entire duration.

You can't suddenly make getting a license harder without also changing a hundred other things too, if you have any intent to preserve any other lifestyle than one that does not require a car, or is not at risk of losing their license. Such a claim is indeed a self-centered one, if you aren't also arguing for the other things as well, simultaneously.

To suggest it without the even referring to the rest alongside it is to create the image of horror, to anyone who isn't already aligned with your premise. And if you weren't intending that statement for people who didn't already agree with you, then the most you could have accomplished was virtue signaling, and I don't know why you would want to do such a horrible thing
Not entirely true. We let one of the massive banks fail. Lehman brothers is no more...
> They can do that because so many people don't price compare anymore before going to Amazon.

There is also the fact that Amazon already has my info, it is worth a buck or two to not have to type all that in on my phone, or at least go through someone else's checkout process.

With Amazon, I can think of something I need, pull out my phone, and with their app have it ordered in minutes.

If I shop around and it takes me ~10 minutes (or more if it is a product category I am not familiar with), and then I give my info to another company that may lose it.
If you have malware on your device you lose already. It can just read memory out of your browser process and steal your passwords.

My comment was was rhetorical. The purpose was to point out that the OP was asking for research to back up a claim but not offering anything but their anecdotal experience for the contrary view.
I found that having a stick in traffic was actually easier for me. I could keep it in one gear which meant not moving my foot from brake to gas (I could just use engine breaking and use just the gas).
That is indeed true and the actual paper [1] makes this clear. The point of the work is to demonstrate the one aspect of Maxwell's demon that was always scientifically possible, but was technologically impossible in Maxwell's time. The demon could sort individual microscopic particles based on some of their properties. These guys have a lattice of atoms and they show that they have the tech to move these atoms around the lattice at will. You can delete the Maxwell demon part of the whole discussion and what they do is still pretty impressive. Unfortunately, to publish in Nature these days you need a catchy story which is why you see it.

[1] https://www.nature.com/articles/s41586-018-0458-7 The abstract and the discussion are fairly readable.
On-campus housing is also a known quantity with an expected 9-month "lease" cycle. You can save money off-campus, but you have to deal with apartments of uncertain quality and landlords who REALLY want a 1-year lease.
There was an attempt to impose regulation on banks that qualify for this designation, with some (limited) success. Republicans have mostly dismantled it by this point though.
Yea, traffic sucks, and I think traffic is eventually going to push people to adopt cars with dynamic radar cruise control systems (that support stop-and-go traffic / low-speed follow). I have such a car (the Toyota Prius Prime), and driving any other regular car in heavy traffic has become insufferable.
It might be similar to silica dust:

I'm not sure about any differences due to the grain size or the presence of the water. (And maybe something unusual would happen when the water inside each droplet boils due to proximity to the flame -- I don't know what would happen as the droplets rupture.)

Don't ask for their email address then. What's the point in having an email address that you have no idea if it's correct or not? You might as well ask them to put in a random string of characters.
I learned to drive in a manual. Now that my son is getting close to driving age, I wanted to teach him in a manual first, like I learned - and then I found out it's damned near impossible to _find_ one any more.
I can still skip from 2-6 on a freeway onramp or 6-4 for passing faster than 8/10 speeds can go 2-3-4-5-6-7-8-9-10.

There's no point revving out all my gears in real world driving, I just want to reach the speed limit as fast as possible then go into overdrive. DCTs are very fast at switching into what they think is your next gear. They're quite slow at switching if you want to switch more gears.
I don't think anybody would argue that server-side rendering could deliver any or all experiences. Clearly even gaming is possible with a thin client (https://parsecgaming.com/).

What you lose at that point is latency. A round-trip to even the closest CDN is going to be vastly slower than rendering the next frame on a GPU with direct access to write to your screen.

It's not that things are impossible server-side. It's that clearly server-side rendering is not the universal answer for more-performant applications.
I asked for an actual quantifier of how much of a 'free market' something is. That's the whole crux of my debate: In attempt to make something more of a 'free market' we cut regulations, which ends up hurting people and which companies take advantage of. Then prices go up, we assume the free market is not free enough, so we cut more regulations. Repeat until people are dying.

A great example of such an issue is one where it was literally impossible for my parents to get any sort of healthcare because it was deemed that they had a pre-existing condition. No insurance provider would bother with them.

And for a lot of Americans paying anything for out of pocket care is impossible. My parents couldn't afford a movie ticket due to the poverty they're in, let alone the price of generic drugs for the myriad of medical issues they're going through. You keep bringing up the example of Singapore which works...but they also have a public option. We're not even to that point yet and making some of these radical changes without care to the poorest of Americans will lead to disaster.
Author of the article here; you'd be truly shocked.
I just can't shake the notion that this is based upon Utopian concepts. The cost in terms of lives attempting to implement Utopian visions in the 20th century can be measured in the 10s of millions. Even if we could pay the upfront cost there is zero assurance that it would be stable or that it would produce better outcomes then what we have now.
But... how? When no one owns a manual, you can't learn to drive stick. My dad had a manual car that he'd kept for 20 years, and I haven't seen one since that went, about 10 years ago. (I could've learned on that had I gotten things together, but didn't. Given its condition near the end, that's probably a good thing.) There's nothing around to learn on.

It's a vicious circle sort of problem at this point. Less manual cars -> can't learn stick -> can't drive stick -> no one buys manuals -> less manual cars.

In the end, I can learn the concept, but I won't really know how to drive stick unless I have a manual... and I'll never buy a manual, so the only possibility is that I'll start off ruining the clutch on some rental. (Or, more likely, I'll go out of my way to rent automatic... but that may not always be possible)
I think you are underestimating your services, overestimating the US services or we have a very different experience in sweden vs finland.

I can get next day shipping on most things pretty cheap, and I can buy most stuff I want to buy that way (including a legally mandated return and warranty policy). The difference I think is that most European cities do not need same-day delivery, since they are not built to have the car-heavy suburban sprawl that US cities have. I'd be surprised if you live in any urban area and don't have a walking distance to a store with the sort of things that same-day amazon delivery usually delivers in the US.

And that's before even talking about that same-day is pretty limited in the US.

I have an S2000. It only ever came in manual. It is insanely fun to drive.
When I learned to drive (early 90s) there was already really no need to learn to drive a stick. None the less, my dad insisted that I learn to drive stick. I liked it so much I bought one a few years later.

I'm also really glad he made me learn, because 15 years later I finally got to Europe and had to rent a car there. It was impossible to find an automatic, but luckily I knew how to drive manual.
Believe it or not, even with the ACA, not everyone can afford it. $150 a month is too much if you're making 15K a year, or around that number + you have children. If I was still in that income bracket when the ACA came out I would have simply had to take the fine and have it wipe my tax return because there was really no other way.

Applets, Flash, JNLP, 0install, ClickOnce? JS is the most popular but it isn't unique.
This is dangerous, as you aren't signaling people behind you if you are braking...

Edit: I would likely soften the "dangerous" wording above. I'm not trying to claim this is guaranteed to get you killed. Just pointing out that bypassing a well established signaling mechanism of your vehicle should be a deliberate act. Not one of convenience.
I once worked for a hardware company which manufactured Set Top Boxes (like TiVO). They could have developed the UI engine in any language, but they chose JavaScript (running on their own custom JS engine). It's surprising how many companies use JavaScript to implement the UI for their hardware devices; to infer that developers only use JS because they don't have a choice is inaccurate.

This is true. Another example is the 2nd and 3rd gen AppleTVs. They were based on iOS but the “apps” for it were all hosted on top of WebKit using Apple’s own markup language - TVML.

While I’m definitely not a fan of the movement toward JS everywhere, I have to admit that of you want to tie your horse to one language, JS is the way to go.
Errant Hyphen May Have Cost Kavanaugh a Vote
There are 50K people in the Marshalls. Imagine a rural town in the US decided to do something like this[0]. Wouldn't the strangeness of the arrangement with the small size of the city prompt a reporter to ask a random farmer or guy on the street? That would be the first thing I'd imagine. Regardless, I get it, unlike a small town, you can't really just ship your reporter on a road trip there without buying a $3K ticket, I'm just hinting that it's hard to tell whether people on the ground are really aware this is going down from just reading about it.

Regarding the politicians it's very possible that the policy makers were sold a one sided perspective on this. People in the pacific just don't have access to information that people elsewhere do. That said, I'm not Marshallese, so I don't know the circumstances of the vote so I'm assuming a lot here. I've just seen a similar script play before in Palau and it usually doesn't turn out well.

[0] Of course, cities can't issue their own currency practically, so the analog doesn't really work.
The other big cost is supply control by the AMA and other physicians associations. In other countries, being a Dr is a prestigious job, but not one that often pays mid-six figures. It's going to be challenging to get into a new, cheaper system without fighting the existing population of well-compensated physicians.
Oh you're right, thank you for pointing that out.
I generally agree with that, but it's worth mentioning that there are exceptions where being able to tell if an individual is registered can be sensitive information (Ashley Madison, Grindr, etc.)
An interesting translation question of "top secret" used as a phrase here, as in "Top Secret", by a translator looking for "Confidential" or similar English relative word, or if it is a matter of "top" as in biggest/most important single secret.

Also, yes, it took the English language many years to come up with the pithier "Loose lips sink ships".
I have one of those too but I find that it's only useful in light traffic. Anything more and it likes to slam on the brakes anytime someone merges into the lane. They still need to work on that software a bit.
Premium is relative. By that standard, a VW Golf is premium. (Arguably you can nowadays get it with options that were very much premium not that long ago)

Series A funding usually means a certain level of viability and risk. Presumably with battery prototypes it is pretty easy to assess if the thing exists at all in some kind of prototype form or not and whether it works at all. When I say due diligence, I'm assuming that stuff was checked and triple checked by investors.

Also, Theranos owed a large part of their funding to the fact that the CEO was cute & female. Stuff like that is super sexist of course but that doesn't make it any less true. Investors were a bit less critical than they might have been and the company certainly got a lot more press and exposure due to this than would otherwise have been the case. Not all investors are idiots.

In any case, I checked, there's very little chance of that happening with the CEO of Solid Power. Looks like a pretty solid linkedin profile for somebody running a company like this.
