> For example, if an Uber eats or Deliveroo driver turns up with the wrong order, they can do literally nothing about it.

No, I would blame the people comitting the fraud rather than the app. The driver can't turn up with the wrong order as the order is faxed to the restauraunt from the app, and when the restaurant is done with the order, then the driver shows up and is given an order id to pick up. The driver can't change the order the restaurant was given.

What could go wrong in this process:

* The app sends the wrong order to the restaurant (highly unlikely. You are talking cosmic ray bitflips or DB corruption)

* The restaurant fails to update an order that is no longer available -- in this case, the consumer is notified that the order is cancelled

* The delivery driver picks up an order not belonging to them, in which case the restaurant should check the order id with the order id the driver asks for. It is very unlikely that drivers will ask for the wrong order

* The driver picks up two orders, and switches them, delivering them to the wrong address. In this case, Uber eats the refund, not the restaurant.

* The restaurant fulfills the wrong order. This does ocassionally happen, as anyone knows who dined at a restaurant when their order was gotten wrong. But it shouldn't happen in the quantities described. Then the restaurant eats the cost.

* The driver fails to deliver the order. One time, I got an order and when I looked inside I saw a strange bottle of juice and a plastic container with a rice dish. Not at all the sushi I ordered. I called the driver and he showed up and apologized. He was fasting during Ramadan and carried food with him to eat after sunset, and he gave me his own food bag instead of the bag he picked up. We exchanged foodbags and everything was fine.

* The restaurant gets the order right and the customer lies about it -- e.g. commits fraud to get a free meal. Hence why this article calls it "dine and dash". This boils down to a dispute between the restaurant and the customer. Here, Uber could start cutting people off the platform if they dispute too many orders, but then you will have a lot of outraged complaints that during a pandemic people are not being allowed to eat, etc. Basically those stealing are putting everyone else into a difficult position as by definition whenever you steal, someone needs to bear a cost that they shouldn't have to bear.
Yeah absolutely — you are creating truly scarce value in that case through an external means (just like an in-game card that lets you do things in the game others can’t do, vs.- “pure collectible” that does something: I tweeted about this here: https://twitter.com/tolmasky/status/1365908735542005762 )

That being said, it will be interesting to see how creators react to these tokens being resold (which is an essential aspect of this). That is to say, in the model you are describing you are taking on a long term relationship in order to demonstrate the scarcity, which is different than a one-time sale of unique piece of art. You will thus take on the problem of scalpers and the realization that many of the superfans you are serving got access to your future rewards through paying a third party much more than you got for the initial sale of the token — which is of course nothing new, this happens with art resale too, it’s just less repeatedly in your face as you provide these benefits over time.
AVR = Augmented Virtual Reality. It's like CGI on steroids, crack, and speed at the same time.

People still have the naivete to trust things because they are on a screen. Preconceived notions cause one to mentally miss or gloss over the great artistry and manipulation in AVR cartoons.

The vid is worth the few minutes. It is a half decent scientific experiment that shows how rocket propulsion really works, and it shows an extra factor left out of the Newton's law argument: Ejective oxidation cannot occur without atmospheric containment pressure. Countless experiments have proven this. Buyer beware what they show you on a screen.

> Reddit has a board of directors, and they might look at KPI's like revenue per user, and notice that Reddit is underperforming by a wide margin compared to other players in the space like Facebook, Instagram and twitter.

Ironically it's often a business opportunity to do the opposite of this, i.e. incumbents are implementing user-hostile features that increase some KPI but that users actually hate, so if you do the opposite then you get the users.

Attracting and retaining users is the most important thing, because without that you're out of business. It's far more profitable to make a dollar each from a billion people than a thousand dollars each from a hundred.

It's easier in some ways but harder in a lot of others. For starters the definition of an "OS" has greatly expanded over time. In the CP/M and even DOS days it was a very primitive shell and some disk I/O routines. Secondly low level knowledge was a lot more common because you needed it to get anything done. You could do some interesting things in BASIC but "real" programs were written in assembly.
Honestly there aren’t a lot of products that were funded this way so I can’t point you to specific resources.

In our case the funding came prepaid with no strings attached. Can’t speak to where in their budgets the funds were allocated from.

I think we should build an ecosystem where companies support open source projects that benefit their companies with great ROI. Unfortunately I don’t know how we get there yet.

There are so many different funding models now for different things (https://humanipo.app/ for example) that there must be a good answer. We should all work together and try harder to find what the best option is.

For me most of the times it means that the problem probably isn’t worth the work.

Which in part is why I never understood the “solve a problem you have mentality” when it comes to writing software. On the occasion that I have an problem that a A) be solved by software and B) does not have a or existing solution that works well, it’ll typically just put it off or give up because the problem is not worth the effort it would take to solve it.

Sure, but users still have to make the decision to install that apk.

They certainly didn't make a decision to install my malware in that apk!

Yes, there's a security risk, but what's really being said here is "we're going to decide what you're allowed to do so you won't hurt yourself".

I'm sure you won't hurt yourself - most iphone users will though.

Or to put it another way: Apple can keep the app store, and even make it the default, but there should be a setting to allow installing things from outside the app store. It can even be behind a few scary popups warning the user of the danger.

Yeah, I agree with you - as long as it's not something as simple as a click-through and ignoring a few worthless scary warnings that everyone ignores anyways and exposes non-technical users to bogus certificates and downloaded malware on Windows and Android. If it was something like MacOS's system integrity protection deactivation where you have to restart the whole system and execute a command through some obscure interface, it could work.
Sure, but that wouldn't have helped in this case since 68K, Alpha, PA-RISC, and S/390 were not "existing" CPUs at the time Rust was invented.

A field is dominated by x - y is not getting paid anything. What is the involvement of x in the life of y? if you get rid of x - would y suddenly change and start doing things that x did..?

Americans workers are paid $x per hour to work. Bangladeshis are paid less than $1 a day. It is the fault of the Americans?

Some people have ample food, others are dying of hunger. Who takes responsibility of the dying people? all the people that have food?

I can see you are pointing out a difference in life outcomes of different people, but how are you tying this with gender? this is my question.. are you suggesting a woman can't take care of her child and be successful at the same time? are you saying women don't have enough agency to make their own life decisions till a savior comes along and makes the right decisions for them? What if it appeals to this woman that she care for her child as a higher priority than trying to go out and increasing some number on a banks database - Are you trying to say the value systems of each individual should be aligned to money alone? that, the ones that have money are successful and the ones that don't have it have failed somehow?

If I make the argument, person x is religious, see how god blessed him with a good life. Look at person y, he's poor and misrable, its because he doesn't follow this religion. Its not a very sound argument because I am just confidently asserting a co-relation where none may exist..
Really? I think it's fantastic to have access to that kind of information from my shell. I've certainly used it for debugging live systems. Sure I could still use something like lsof and have it monkey around with the extra syscalls, but it's just really cool and useful to be able to use it with one less binary.

The ideal school lets every student learn at their own pace, using a tablet with pre-recorded lectures and computer-graded quizzes. Instead of lecturing, teachers tutor small groups that did poorly on the same quiz, to help them understand the material and progress. This is the mastery learning model [0]. Classroom experiments have shown that mastery learning students learn much more with the same time spent with teachers [1] [2].

This shows that society knows how to educate children equitably and at scale. Unfortunately, it doesn't do it.

It's funny that you mentioned having to install Rust to use some Python because, for us non-Python users, everything needs Python :). I don't use Python at all, but I need both versions installed.

Just pointing out that many people are already wearing that shoe.

Python is the Lingua Franca of getting shit done. Rust is seemingly becoming the Lingua Franca of [more] secure code.

It's about your word, not the law.

Although the law says that clause is not enforceable, that does not mean you cannot abide by the terms.

I.e. reneging on your agreement is reneging on it, plain and simple. Signing the agreement knowing you're going to renege on it is unethical.

> But actually do cross it out before signing, if that makes you feel any better.

Man up and line it out if you aren't going to abide by it.
It is kind of ok, given that 4.1 is the most widespread, however the latest OpenGL version is 4.6, which no book covers.

Even the red book only goes up to 4.5 and the one need to track down the Kronos documentation.

Then there is Vulkan as its successor (I doubt that there will ever be a new GL version), and mesh shaders are the future of GPGPU programming

HN Feature Request: Enable an additional short description for URL submissions
One HN guideline that bothers me from time to time (even though I recognize its necessity) is the "original titles" rule, so I'd like a discussion on a potential solution.

There are several issues with the rule:

1. The submission might be a Web page on a blog or forum, where the title will surely miss important context from the perspective of HN, as opposed to accessing the page from its native forum, blog, or the like, and if one isn't a regular on the forum or blog.

2. Sites like Wikipedia often have article titles which give absolutely no indication as to why the topic might be interesting. To make matters worse, the interesting stuff is sometimes buried deep in the article. Other than Wikipedia, some pages or PDFs on legal or "bureaucratic" topics can have inscrutable titles and be very long. In such cases it seems like allowing a short note from the submitter, like "page 97 is interesting", might be useful.

3. HN has particular interests, and whoever writes the article and/or title probably didn't write it with HN in mind.

4. Many authors simply devote little to no time to choosing a good title.

These issues have been discussed previously, examples:

https://news.ycombinator.com/item?id=5142851

https://news.ycombinator.com/item?id=6572466

https://news.ycombinator.com/item?id=1169151

https://news.ycombinator.com/item?id=8608162

Consider this change to HN: when submitting a title and a URL, it should be possible to give an additional short one-line text description of the submission. Afterwards the description could be displayed next to the title and domain, and given less weight visually than the title. The latter could be accomplished by displaying it faded and with smaller letter size.

The most recent relevant (although mild) example I happened upon is this short page that aims to give intuition about kernel density estimation (KDE, basically a better histogram): https://mathisonian.github.io/kde/
I'll give you directly rewriting the source tree as a list, that is pretty cool. But about 70% of the coolness of macros can in principle be done in a C-like. (I'm doing it!) It just comes out a bit ugly cause C-like parse trees are inherently ugly, imo, cause the language imposes a more diverse structure.

Pattern matching would probably help a ton for destructuring - being able to take "$a + $b" and decompose "2 + 3" into "a=2, b=3", but that's kind of difficult. There's ways you could do it cleanly, like imposing a very predictable structure on your AST nodes, but they end up sort of reinventing Lisp through the backdoor. Luckily you don't need that for most macros, afaict.
Windows is not even supported by MIT Scheme anymore.

There is also the #lang sicp for Racket that needs no modification from the code in the book, to my knowledge.

Chibi has explicit renaming macros. If you really want less hygiene than that, you can implement defmacro on top of er-macro-transformer.

Edit: er-macro-transformer IS unhygienic unless you tell it otherwise, much like gensym, except all renamed bindings introduced in the same macro invocation are the same. Gensym is of course available as well
While looking into the BME680 for a fun little indoor air quality monitoring project, I found this neat article showing what a humidity sensor looks like under a scanning electron microscope (SEM). The linked article itself was found from this hackaday article comparing the BME280 (like the BME680 but no MOX sensor) with other popular humidity sensors, such as the DHT22:

technically illitare here, pardon the stupid question. I hear so much buzz around k8s/docker/AWS/GCP/Azure and all that but simply don't understand what they actually do. if you go with the extra effort to run your product on you own infrastructure, what do you need Heroku/Flynn et al for? isn't the idea of PaaS to take care of server/database/hardware management etc for you, so you can focus on developing your product?

On issues of information privacy, I think that most people here are likely to be informed enough to form opinions that they can back with reasoning, as was done here. And the facts are that the policy that Little League has does not have to be in place.
I spend all my time these days in S7 Scheme and ANSI C to be honest. (I guess technically in C, and in Scheme-in-C!) So I won't argue against the beauty of C when you want to know exactly what the computer is doing... It's gotten to the point where I just don't even want C++ anymore, I'm becoming one of those weirdos, haha. :-)
You could easily model how increased retention/engagement rates would translate to increased microtransaction revenue from drastically decreased load times. You could even bucket test it if you wanted to directly quantify the results, but I'm sure that the cost payback would be a matter of days.
> First of all, I'm not against porn, but most of reddit porn isn't empowering people, it's selling onlyfans

A mom loses her husband to covid at 40. Hasn't worked in 20 years, she's decent looking, a little risky, so she decides to give OnlyFans a shot as a way to empower herself to feed her family.

Would it be better she go apply at strip clubs that are a bit more seedier and less anonymous and give her less control over her paycheck/livelihood?

How is this different than a youtube star sharing their content? Should we just not allow any original content at all?

> later reddit will ban porn unless it's verified

Many of the top subs (all the gonewild, realgirls, teen but legal type subs) do require verification processes to ensure legal and unique original content.

I can't say if there's much victimization or exploitative ops on there, haven't really looked and don't care to because I'm afraid of what exists on Reddit I don't already know about that's bad enough: like https://www.reddit.com/r/eyeblech <-- not porn, still not safe for sanity or life in general...

I'd hope anything with cp or the likes would get caught and shut down, and anything with rape (real OR fake), and revenge porn, etc...

But there's some reddits where people post (often) anonymously to boost their self-image too like /r/NormalNudes which describes itself as:

"Normal Nudes is an effort to have users submit their own pictures in order to build a library of what normal, every day human bodies look like. We should strive to love our bodies for what they are, and understand there are MANY healthy body types that are beautiful that don't necessarily conform to the standards we might see in magazines or on television."

I don't think there's ever going to be a perfect way for society to embrace the seedier side of things, and also police everything bad and still retain a "free" censorship-free (as much as can be expected and safe) ... but honestly I think Reddit does better than Tumblr or Twitter which are less structured on how they moderate things being less "topical" and less about multiple communities.

I think the best bet is probably have a board of porn overseers that basically are defacto mods in all porn subs and can override any other mod-and act swiftly when an issue comes to their attention. That would probably be the best they could possibly do.
On the Experience of Being Poor-Ish, for People Who Aren't
But in reality, the grass is orange and the sky is brown.
Back in dialup/DSL days I discovered a texture compression issue in America's Army (the free US Army game) that doubled its download/install size. Typical download times were about a day and the resume mechanism was poor, so this had the potential to save a lot of grief, not to mention hosting costs. I emailed them, they banned me for hacking, and the next version still had the same issue. Shrug.
It's very easy to manipulate votes on HN as you can see.
In the real world, computers don't start with blank tapes. Whether you can reversibly compress a noisy tape, then, is a question of the tape's entropy. If you can't create blank tape on which to work, you can't do any computing, reversible or otherwise.
