I agree that if you have a background in a common programming language, R is not intuitive. I know it from personal experience.
However, for someone with no programming background, R may be quite reasonable. Just judging by my daughter's experience.
Costco, Target and Safeway have to pay to maintain inventory in their stores, and thus have 'skin in the game'. Amazon can merely 'watch' what sells, and copy.

AFAIK, brick-mortar stores have to buy products; they don't get it for free. If they banked on sales of product A that they thought they could make a generic brand out of, and it didn't work, it cost them some money and real-estate. H

However, Amazon just has to watch people's 'browsing history' without paying a dime to the seller. If the product sells well, its good. If not, no loss of any kind for Amazon. Its a win-win for them (alone).

> This comes up a lot nowadays due to the 2010-era explosion of "skinner box" games on mobile platforms e.g. Candy Crush, or presumably Farmville and Clash of Clans. I saw a lot of people around me get addicted to these games, and seeing how much time they put into them made me pro-actively avoid them at all costs.

It's interesting to look at those games from a business/economic perspective.

Imagine you create a mobile game called "Data Entry Crush" where the game would send players an image of a document and they would carefully type in the text for it. You give the game to players for free. On the backend, you sell this as a service to companies needing data entry where they pay you to turn their images into text.

In other words, like Mechanical Turk, without paying the Turks.

Of course, this would never fly because people don't find data entry very fun and it's pretty obvious to them that they are being had. They know they are providing something of value to you and won't do it for free.

What Candy Crush and friends did was find an exploitable loophole in human pyschology. It's hard to get people to do something that clearly looks like valuable work for free. But it turns out people aren't good at realizing their own attention itself has value. So what do you do? Make a game that's a little fun to play to keep people going, and then pepper it with ads. Those ads take some of the player's attention but since humans seem to undervalue that resource, the players allow it to happen without getting irate or expecting compensation.

And then, as before, you make all your money on the back end. You let companies pay you to put those ads in front of people. It's like an arbitrage opportunity where human attention is more valuable to (A) companies than it is to (B) the individuals who have it, so you take it from B, sell it to A, and keep the profit.

I read your comment as "create as many tickets as necessary to throw off management's understanding of the effort and complexity of the problem." Creating more tasks than necessary sounds like a waste of everybody's time.

As I noted in a parallel comment, on my team, developers are never creating tasks on their own or in a vacuum. It's done as a team effort during planning meetings.

Perhaps I should add that my boss (senior director) has never asked me about my board, velocity, or anything like that. Discussion is higher level - "is project X on schedule?" or "are you going to miss anything on your roadmap?" not "why is task X or story Y not done yet?" If your director is asking that, he has too much time on his hands.

What kind of engine do you want to make and what is your goal by making that engine?

The generic, one-size-fits-some advice is: Go and make three games, and by the time you’re done with the third game, you’ll have a clear idea of what you want from an engine.
That does seem like a valid concern.

Not sure what a solution might be.

What HN needs in order to function well is not be taken over by political rage-threads, which are not about intellectual curiosity (for one thing, they're all the same).
Sorry.

For clarity of thought I mean if you decide to make a game you might want to work out what a game is to you. Like a mission statement that you can use as a razor to judge your subsequent ideas.

Design pillars are similar but about specific aspects of a game. A set of principles you can use to guide development.
The most interesting thing (to me) about the Gelman page is that by the PPPS, he's hedging all of his most significant criticisms:

"The data as reported are also consistent with infection rates of 2% or 4%. Indeed, as I wrote above, 3% seems like a plausible number. As I wrote above, “I’m not saying that the claims in the above-linked paper are wrong,” and I’m certainly not saying we should take our skepticism in their specific claims and use that as evidence in favor of a null hypothesis. I think we just need to accept some uncertainty here. The Bendavid et al. study is problematic if it is taken as strong evidence for those particular estimates, but it’s valuable if it’s considered as one piece of information that’s part of a big picture that remains uncertain. When I wrote that the authors of the article owe us all an apology, I didn’t mean they owed us an apology for doing the study, I meant they owed us an apology for avoidable errors in the statistical analysis that led to overconfident claims. But, again, let’s not make the opposite mistake of using uncertainty as a way to affirm a null hypothesis."

The twitterthink reaction to this study has been vicious, mostly based on amateur re-hashes of the Gelman critique, which even Gelman himself doesn't really believe.
I don't think anyone is argue for one instead of the other.

Why not a little bit of both? Can we not think about system and data driven improvement while also at the same time apologize for our mistake?

Vast majority of people rent in Zurich. I lived in multiple countries (US, Australia, Europe - Germany, Austria and more) and apartments in Zurich are better maintained than anywhere else I've seen. You can find cramped, if that's what you want, but there is plenty large apartments - bigger than US or Australian apartments. E.g. looking at our corner of the city, there are 2 bedroom 85 - 120m2, 3 bedroom 120 - 160 m2 places. In Sydney, we had a 75m2 2BR with tiny bedrooms and it was a typical apartment there.
If you want to live in a house, Zurich is the wrong place, you'll probably need to commute.
Sorry.

This was me throwing peanuts at a thread that I had hoped would get flagged into the abyss anyway, and already by my reading contained a lot of ironic Friday afternoon eye rolling. A certain sense of gallows humor here, I felt.

I can see my comment is pretty damaging if it gets any actual views (which I didn’t expect it to, but that’s no excuse!)

In another setting it might make a good womp womp dad joke — as intended — but not here.

We have to peg quality with rigorous testing or else cost (time spent) will be variable upwards to infinity (due to accumulation of untenable technical debt).

Therefore, if cost must be pegged due to limited time/funds and quality must be pegged due to existential risk then quantity/richness of features must float and be flexible.

All good product owners will learn this truth eventually.

vctrs [0] is the latest effort by the Rstudio developers to help people write type-stable code. The R standard library has a lot of issues with silently casting types, but the wonderful thing about it being so scheme-like is that many of these things can be evolved through libraries.

It's more of a language/compiler thing than a hardware one. Hardware support for bit shifting exists on every processor I've ever used. The only real question from a performance standpoint is whether the language you are using will automatically generate optimal code for the x*2 and x/2 cases. Most of the time, it's not worth worrying about: you do it in the clearest way possible (i.e. as a math expression, not a bit shift) and only look at forcing the optimization if you have a performance problem.
After all the effort they put in, making themselves look like shills trying conjure up post-hoc justifications for his idiocy and he just comes out and throws them all under the bus by claiming he was being "Sarcastic". Unreal.

Intraview – Platform which will help you to prepare for your interview
The other advantage other than greppabilty/documentation is that the compiler will limit what the static_cast does. Since a c style cast can be a reinterpret cast or a const cast you do lose some compiler provided protection.
Not strictly, and I'm not sure what's public knowledge and what isn't, but as I understand it the biggest win was being able to scale quickly (especially during the holiday season) without having to put in orders for hardware months in advance. As I understand it, cost wasn't a driving factor in the migration. I think with regards to performance, it's a bit hard; comparing a cloud-native solution to a custom solution running on a VM on a server you manage can be really tough to compare.
Can you take it off?
Hello everyone!
I am excited to launch https://www.intraview.co today. My aim with https://www.intraview.co is to provide the developers with a question bank and a platform where they can go to test their knowledge, find what they are missing, improve and share their personal questions with the community. When logged in, you can bookmark questions to revisit them later and also share your own questions with the community. I just launched it today and I am open to feedback to improve the platform further.
I am really struggling to understand the benchmark output quoted.

Can anyone elaborate what does benchmark=3/4 ns mean, and the count? Is the set-up part of the benchmark (test structure suggest not, but just to make sure)?

The only way I can read it is that 4000 divisions takes 4ns, and 4000 shift-rights takes 3ns, but that only has 1 digit of precision, which makes it unusable for comparison, but even then suggests a 25%/33% difference, which is not insignificant.

Also, the VM seems to optimise multiply out, so it must be doing it for a reason.
Because they assume anyone buying a drive that small is price-sensitive. Except they didn't actually lower the price when they crippled the drives with SMR.
> I think books on software management and process are mostly lost on someone who hasn't been involved in the process.

I think that's true and fair. However, once some experience has been acquired, I believe it's helpful to evaluate whether it's good experience or bad experience. Comparisons against the literature can be helpful at that point. Case in point: I tried reading 'The Psychology of Computer Programming' in college, but it didn't make much sense to me. Coming to it 15 years later, I realize it'd have been the perfect companion to my first five years in industry, naming and describing problems I'd faced and solutions that only came through experience more painful than reading.
> The main point IMO is that making an engine implies more than just making the tech needed to power a game.

Then I think we have a very fundamental disagreement here. Your definition for “engine” is definitely not mine.

If we can’t talk about the engine for The Witness we are at a loss, because there isn’t a different word that we could reasonably use, besides “engine”.
I have a laptop with an encrypted LVM drive that has a separate /home partition with very little space left for user files. I installed some Flatpaks and got a disk-space warning.

I'm not surprised, but Flatpaks install everything in the user's home directory. So if you know you're going to be using Flatpak apps, make /home bigger.
They were. The connectors at the end of the drives were different and that was all (adapters were common, probably still available)

There's also scsi 3.5" drives out there. Some ThinkPads had them. In fact, those drives were 2.88MB, just like on the NeXT, the 1.44 was common but one of a large number of capacities in that form factor...

If you do this, use dd, not cat. Why? dd has this

noerror
continue after read errors

You're going to get errors. Lots of errors! However, 80% or so of the time, most of the disk is still recoverable, but only if you use the right tools.

It's going to be slow, real slow. A few minutes a disk with errors.

Now that I think of it, you can probably swap the NeXT and thinkpad drives with a little effort. I bet there's a good arbitrage on eBay here if I'm right.

There's systems that go the other way, sd card/usb disk to fake floppy but what I really want is usb to fake floppy. In this model the usb exposes itself as a configurable given capacity drive on both ends of the pipe, fake on both ends

At the modern computer I copy over the files to the fake drive disk by disk and on the old computer I tap enter accordingly. Then someone can do a 20 disk install or whatever without a bunch of effort. It's not a hard device to make but i checked and i still don't see it
Please refer to the (current) top comment.
The only meaningful reason to prefer static_cast over C-style casts is easy greppability.

That's not just it: static_cast will also result in a compiler error when trying to cast things which don't make sense so that's extra safety.
That seems like a big stretch. Is globalism not a real set of beliefs, then? Like, anti-tariff, pro-free-trade, free movement?
A common narrative on China, prevalent in the United States, often says that China’s top-down, monolithic innovation policy has led to economic success. The report calls this a “myth.” Ernst argues that things are never so simple nor so homogeneous in China. The report quotes Harvard’s Mark Wu: “What makes China complicated is that, while the Party-state holds vast control levers, it allows market forces to play out in huge swaths of the economy.”
I partly agree but would put it differently. When an obscure topic (like ultraviolet blood irradiation) is connected to some trigger in the daily news, people will end up arguing about the daily news rather than delving into the obscure topic. So from an HN point of view, that's the worst time for the topic to appear. HN should be countercyclical instead. This case has made that even clearer to me than it already was.

At the same time, HN is not for internet ragewar and users here should know enough not to feed those flames.

As someone who works in policy, his response was about as good as I could hope for from someone not involved in policy normally. Talking privately to credible people, working with experts, and getting the message to media channels, are all what you're supposed to do. Him shouting on Twitter wouldn't have accomplished anything.

Author here. Would your behaviour be different if you knew that a cloth mask lets through 30 to 97% of COVID-19 particles rather than thinking they can filter almost all infective particles? If so, this article is for you.

This statement in the article is completely disingenuous. The study in question[1] was looking at whether wearing a mask protects the wearer from getting infected. The primary purpose of wearing the mask is to prevent the wearer from infecting others. These are unrelated!

Well personally, I'd like to see those other folks penalized as well. There's plenty of money to be made running markets; there's plenty to be made competing in them. Having both isn't necessary.

But the important distinction here is market share. Amazon has circa half of e-commerce. So Amazon especially should have to pick a lane and stay in it.

I completely agree that you don’t need to assume ill intent. But by that same token, the fact that a paradigm or process isn’t invulnerable does not mean that it shouldn’t be used.

Bureaucracy, heavyweight process, and all rest are ways that systems protect themselves. Wasteful though, which is why new paradigms such as Agile come along.

Now the Agile ecosystem has become corrupted by a process not comparable to all the above. Not solvable by those means either. It’s a toughie.

You claim I'm "debating a strawman" but then quote the article that literally says they have no alternative in mind (my chief critique) and point towards artificial intelligence to solve the issue somehow.

This Lemur Pro is an amazing deal. An i7/40G/1TB $1700 Linux laptop that weighs about as much as the now discontinued Macbook. That's just a dream travel machine.
