It only makes sense if they are capturing analytics on lost revenue and can see that the addition earning from the fee outweigh the direct costs of abandon carts.

The loss of goodwill is a little more difficult to capture, so I can see them not knowing this cost.
To be more clear I visited an Amazon FC during the first week when I joined Amazon in one of their operations teams, in which I have then spent 4 years.

There are processes in place and physical things that are completely different from what the original commenter says and those things prevent the issues (having items on another shelf multiple feet below where they should be) from being possible.
> the delivery fee goes to the driver (mostly, I hope)

I don't think I've ever [edit: should read "recently", I surely saw some early ones that didn't] seen one that doesn't specify that the driver doesn't get the money. Presumably because when they (most pizza delivery places do this now, plus I think Jimmy Johns does it, probably others too) first started adding those fees some years back, people assumed it was for the driver and stopped tipping, since it's usually about as much as a decent tip would be.

Ever-rising, often-sneaky (different prices for delivery, much worse coupons for delivery vs. pick-up) increases in delivery costs have me thinking like my parents used to, and rarely ordering delivery anymore. There was a golden age in the late 90s and early '00s when delivery was pretty damn cheap, basically just $3-5 for a tip. It's over.
Was thinking the same. All you need is a tub and a drill.

Having worked in the OTA space, every time I see their (sometimes funny) ads, I want to call them Booking.Nope

OTA make comparisons a bit easier, but everything is negotiated and contractually controlled to keep people from just going to the hotel directly. Secret hotel prices (like HotWire if that still exists (Expedia) or Travelocity's Top Secret hotels if that still exists (also Expedia)) are an even more crazy negotiation. Hotel Tonight at least used to contact the hotel chains every day for that day's options, though since they were bought by AirBnB who knows what they do.

These days I just find a nice hotel and book with them/their system directly. Airlines too, since airlines fail to give all their options to the OTAs.

In some ways its sad that aggregators don't work all that well in the main travel industry (Flight/Hotel/Car) but travel is extremely complicated, highly competitive and still very fractured except for airlines. Pricing comparisons are not very useful since they are so mangled and obfuscated that you may as well just go to several sites and do it yourself by hand. For example Spirit Airlines used to give us prices for their tickets at $X and were always cheaper than everyone else; yet once you booked at that price they hit you for everything extra (bags, res, for all I know oxygen) then our customers complained we were fooling them and the real cost was higher.
While I'm generally inclined to agree with downvotes because you don't really explain your reasoning - this is a post on an openly biased subreddit (anti-work) and it doesn't source any of the information given.

It's quite openly an anti-corp hit post and it's not trying to inform readers. If it were then I wouldn't have to go research if what the poster is saying isn't completely fabricated.
Moreover, I don’t know what kind of app is used in the screenshot, and the information may very well be correct, but the Reddit post is unsourced. So someone in the comments posted a link to a Metro article as source, which links to a screenshot posted on Twitter. Might as well post this HN thread on Twitter to complete the ouroboros, perhaps a news site will pick it up next…
I really dislike JavaScript for a number of reasons. Dart gives me more distance from it than TypeScript. Of course, I can't avoid it, but I don't have to deal with many annoyances such as which 'this' is this? Should I put 'this' into a var called 'self' to be safe? That's just one example of how JavaScript and I don't get along. I understand some people have brains that think this way, but mine doesn't

Compilers can easily lower tail recursion into loops, but not general tail calls between arbitrary (possibly unknown, indirect) functions.

The best they can do are trampolines, which come with a high performance cost.
Always feel bad if it comes from within. If it comes from others/friends/peers, nothing to feel bad about.

So let me ask you. If those peers did not make you feel bad, would you feel bad on your own that you shouldn't have splurged ? If answer is No, then move on. Nothing to see here.

People always have opinions. Sometimes they are good, sometimes they are whatever. You do what works best for you. Listen to your peers but ultimately it is your life. If you want to splurge and are willing to accept consequences (good or bad), your call. It is called Freedom.

This is just the fallacy of definition. Technically being anti-racist or anti-terrorism is "bigotry" on a fallaciously "strict" interpretation of some short definition of the word if one refuses to acknowledge its social and historical context (and how the word is used in the real world.)

> but outright exploited workers/drivers

Out of curiosity, what coercive power does Uber wield that allows them to exploit workers all while non-exploitative employers have struggled to find anyone to hire? We've been living through what has been possibly the best job market in history for most of Uber's existence. Locally, we've been at full employment for nearly a decade now (less a few months during the height of COVID). It's certainly not a matter of "They have no other choice".
NASA needs to get taught on how to do live streams in 2022. For such a long-awaited presentation from one of the biggest space agencies in the world the quality of the live stream is terrible. Low video quality (720p highest), constant lag, microphone issues (wrong microphone open leading to NASA-ASMR) and failing connections to external locations.

I wish they put more effort into this. It deserves it!
How is ECMAScript 6 (high level language) related to WebAssembly (low level target)?
Honestly and with all due respect they could just release the images, etc. with some text with a video explainer to follow. The hype machine is broken and taking away from the actual awesomeness of the project.
Tail-calls is fundamentally something that the compiler _cannot_ solve. Trust me, if there was a way we would have avoided ourselves all this work.

The issue is that to avoid stack blow-up you need the engine to recycle stack frames. You might argue that this could happen implicitly in the VM, with all the calls in tail position being automatically converted to tail-calls. The problem with this is that in WebAssembly (and JavaScript) the call stack is observable via the .stack property of thrown exceptions.

Since an implicit conversion would be observable engines cannot simply optimize the problem away, and that is the reason why new opcodes (return_call/return_call_indirect) are actually required at the WASM level.

For the specific case of direct calls (return_call opcode) the compiler could solve the problem by inlining, with some luck. But for the case of return_call_indirect there is no other possible solution.
I always thought it would be interesting to see a calculator that takes a finished product and shows how many raw resources went into it. For example, put in a load of bread, and it shows how big of a wheat field it needed, how much oil to transport it to market, etc. Put in a cell phone and it shows how many minerals were mined. Showing labor hours would also be neat.

Just a few examples for products across different sectors would be interesting.
It lost me at calling people “casual text producers”.
This is unfortunate, IMHO. DSLR's are (far) superior in terms of battery life. This was inevitable, of course. It is similar to the transition from dumb phone to smart phones (which, interestingly, had a similar tradeoff!)
A more civilized way of solving the problem is by customs. Foreign products don't have unfair advantages and the country can use the collected money to produce public services.
Are you talking about people who appear inebriated? Because that's all I saw. Nothing truly NSFW. Just went back for another dozen. No inappropriate skin showing, no illegal activities (unless, of course, there are underage people drinking, but it's hard to tell that for sure.)
I've done this for years, quite convenient. I also have an NFC tag with the WiFi which works quicker (no need to open a QR scanner and no need to focus on the image for a sec) but I'm not sure if iOS supports it. I've put the tag behind the wifi "frame" so that you can just tap it instead of scanning it.

Android also has the option to "share" wifi via a QR code from the WiFi settings menu. It is quick and much easier than reading out the password to someone else.
I mean even if Uber paid for it the general consensus in economics is improving market efficiency is a net good. Like yeah obv it sucks for taxi drivers but the position of a lot of governments (EU more than most) is that consumer benefit at the expense of business is fine. So kinda inconsistent for the EU to say they'll go screw with other companies for consumer benefit but then "oh no not the poor cabbies, we can't let the cabbies make less money!" Also there's a lot of rent-seeking in traditional cab industry that comes from stuff like the high cost of entry and the lobbying to keep it in place so taking that out should make a better economic outcome.

I work for PostNord, the Danish postal service (possibly the largest parcel service, not sure how well GLS is doing these days), and Amazon has been complaining about our "parcel quality", because some parcels are not delivered within 24 hours. (Even though it might take 3-5 days to even get to us)

The contents of the chapters are the same, but the exercises at the ends of the chapters have been rewritten, by the publisher's lackeys, not by the original authors, for the international edition, very poorly by all accounts.

There is a question that you can apply to any scenario that will almost always give you "the right answer":

What are you optimizing for?

If you are optimizing for the most experience with emerging tech, then no it's not wrong, you need to get access to it.

If you are optimizing for reducing e-waste, then you should be probably getting older tech and reusing it or selling tech that you've repaired.

If you are optimizing for minimal possessions, then yes, it could be bad if that means more objects.

If you are trading in and trading up and optimizing for "tech that holds value" then no, it's not wrong.

Often when people pass value judgements it's because they are optimizing for a different thing, and low and behold, that's where disagreements stem from.
Do you want to get a union in your warehouse? Because this is how you get a union in your warehouse.

Companies that avoid unionization (most of them, these days) make at least some attempt to treat the workers as partners and human beings: pay them well and treat them well. Obviously there are other factors in play and sometimes that's just corporate BS, but it helps.

Amazon, from what I can tell from the outside, does not believe in that.

> exploited

That's a completely subjective term that just describes that one part of the transaction does not like the deal that they entered voluntarily. That's why many people, including myself, consider the usage of this term an attempt at manipulation.

In almost any country where it operated or operates, Uber was not and is not a monopoly, neither on taxi clients, nor on labour. There are multiple taxi apps a driver can work for, and many shift between them in a span of one shift. And traditional taxi parks, although lost a significant market share, have not disappeared. Therefore, a price of a driver's labour is still dictated by an open market and not by Uber.

What changed, though, almost everywhere, is taxi apps made the market more fluid and effective, and turned over a lot of mechanisms which taxi drivers used to "exploit" clients. You just have to travel to a city that still mandates government-backed monopoly, like Istanbul, and compare the level of prices, service and reliability to what the ordinary Uber experience is like.

> Uber has essentially not just broken laws

Laws can be, and often are, immoral. And any laws that limit the ability of parties on the free market to transact with each other however they wish, including taxi medallions or similar systems, undoubtedly are.
A lot of this happens because different managers have different metrics/KPIs they are optimizing around and they all find "good places" to do things to help meet their goals. The secondary effects aren't considered. One managers quest for outperforming their goals comes at the expense of another managers goals.

With regard to tire costs… for any EV owners in the US make sure to buy tires at a place that honors the tread wear warranty. Although my tires are high end which hurts the wallet, I regularly get $500 - $600 tread wear warranty credit applied to the purchase because I remember to ask for it, bringing the cost down a lot.

Costco is the absolute worst for this in my experience. They won’t honor the warranty until the tread level is dangerous. Discount Tires (also branded as America’s Tires in some states) is the best and they’re all over which is handy on road trips.

Fundamentally, a cryptographic system that allows a key fob to authenticate itself with one-way communication to a car and does not require a real-time clock in the key fob is hard and maybe impossible to get right. One can certainly do better than what Honda did, but anything that checks all the boxes one would like needs some way to prevent replay even over many keypresses with no successful unlocks, and that needs either something visible to the car to change when the owner presses the button 100 times far away from the car (e.g. the time) or needs a form of communication in which the key isn’t simply broadcasting bearer tokens to the world.

Specifically when you are setting up your shot with the DSLR you are looking at a ground-glass screen and the sensor and screen can be turned off.

For a mirrorless camera the sensor and screen are on when you are setting up.

The flip side is that a mirrorless camera makes a great video camera with some caveats. For instance if you want to do a shot that smoothly zooms in or out you have a rocker control on a real video camera that you can hold steadily and it does just that. I can't do the same with a mirrorless lens because I can't turn the zoom ring on a lens very smoothly.
In fact, you want the dismiss button to be easily discovered and used. Dismissals are an important signal about the quality of the content; just as important as clicks.

He did jumped the gun. The author Carolyn Chen made some very compelling arguments saying corporatized Buddhism is unrecognizable. Carolyn Chen is arguing corporatized Buddhism is a new religion that celebrates 70+hour work weeks and the celebrity CEO.

"What we see in American religion, even if it is practiced in a corporate setting, is often the question, “How can the group help the individual realize themselves?” Whereas in other cultures this question tends to be reversed: “How can the individual help realize the goals of the group?” Interestingly enough, I think that companies have been able to command great self-sacrifice from Americans in a way that no other institution can today. I would argue that companies or workplaces have become the new faith communities that are replacing organized religion."
