I think you should consider the possibility that they are deliberately deceiving you. That certainly seems to be the case with the 'go fast' video. Public information on the gimbal camera equipment is lacking, but if the USN is willing to lie about the go fast video, they'd be willing to mislead people about the others as well.

I prefer to put "var" into the loop header because the combination of two types is hard to read. It's easier to read (for me!) when the type of the key and the type of the value are separated, like they are on the first two lines of the loop body.

final SomeLongType key = x.getKey();
final AnotherLongType value = x.getValue();

I disagree. The pics looks good on a phone, but when you compare a large print vs a full frame camera, the difference is obvious.

Amazon paid 7 billion in content costs this year, I would estimate it cost another 1.5billion to do the distribution. That doesn't include internal development costs, advertising costs, etc.

Prime all together only made 14 billion. Considering that prime almost assuredly doesn't cover its 2day shipping we can be very sure, the video unit is _certainly_ not positive.

What's even more important is this quote from Bezos, which directly states it's their strategy:

"We get to monetize [our subscription video] in a very unusual way," Bezos said. "When we win a Golden Globe, it helps us sell more shoes. And it does that in a very direct way. Because if you look at Prime members, they buy more on Amazon than non-Prime members, and one of the reasons they do that is once they pay their annual fee, they're looking around to see, 'How can I get more value out of the program?' And so they look across more categories — they shop more. A lot of their behaviors change in ways that are very attractive to us as a business. And the customers utilize more of our services"

Hi HN! I'm Marinos, engineer and Parachute founder

We originally developed Checkup as a way for changemakers around the world to alert their colleagues and loved ones in case they suddenly "go missing". However, we realized that, amid COVID-19, others can also benefit from this powerful feature, and today we are making it available to everyone on Parachute

Unlike apps that do 24x7 location sharing, Checkup keeps your location history private, and only releases it in the event you fail to mark yourself safe. This conditional release allows you to get the life-saving benefits of others having access to your location, but without having to sacrifice your privacy 24x7

Parachute is an independent, VC-free, tracker-free personal safety app with 4600+ 5-star reviews from around the world

Happy to hear your thoughts and answer any questions. You can also email me directly at marinos@parachute.live. Stay safe, healthy and sane
In real numbers, there doesn't exist such a thing as "infinitely small number" that is apart from zero. Yes, there exists infinitely many numbers between any minisculely small number and zero, but the way they are defined, every single number you can grasp, is finitely small. The "infinitely" small gap is inaccessible. In some other number systems it isn't, but in the standard reals it is.

That means that the "infinitely small" doesn't exist; "smallest apart from zero" doesn't exist either.

Is this Simpon's paradox at work? Google is more trusted than Amazon in Gen-Z Adults, Millennials, and Gen-X, but overall Amazon beats Google. Google doesn't even make the top-25 of Boomers, but Amazon is #11. That's a little weird; does it explain the overall result?

I was prepared to blow my then 6th or 7th grade daughter's mind with this algebraic proof. I started by asking if 0.999... = 1, to which she said "no." I rephrased it and said it is equal, do you know why? She thought for a moment and said "1/9 is 0.111..., so 9/9 is 0.999... and 9/9 is 1." And I had to admit she had a far better solution than I did.
Yes, although for me this conception of infinity as a process also captures why there are probably no actual infinite things in the universe, only in silly games with numbers.

In your proof you say

>And here is the logical (induction) step: if you shift the decimal point by an infinite number of places, then there are still an infinite number of 9s to the right

This is not how induction works. The induction shows that you can shift the decimal point any finite number of steps to the right and there will still be infinite 9's after it. If you want to show something is still true after infinity steps, you require transfinite induction, but this doesn't make sense because the '...' decimal representation only represents a countably infinte number of 9's.

This is the same reason 0.9bar7 doesn't make sense - because decimal representations only have countably many digits.
The way different societies organize themselves is they tend to incentivize behavior that is beneficial to their continuation. Society who incentivizes non-beneficial behavior will eventually collapse and be replaced by a more fitting one.

If society is to give out free passes for suboptimal behavior to anyone, it's going to be to those who provide it the most value. Kind of like Amazon does to a lot of people right now.
I haven't (and won't) opine on whether or not I feel those sorts of laws are reasonable: that's not the point of my original comment. The point of my comment is simply to point out that there may be restrictions in your jurisdiction and you should be aware of them. If you choose to engage in civil disobedience on this topic, that's entirely your choice. But ignorance of the law isn't a great excuse for violating it.
> However I think there are other cases where the strengths of C still add value; for instance in game development you're largely trying to do high-throughput processing over large swaths of structured data

That world is dominated by C++ for the most part, though. So D's -betterC would be fighting against an incumbent that is itself also already a "better C".

What value does D's -betterC bring to the table here? Skimming through it, it doesn't look like there's any compelling reason to switch to -betterC from an existing C++ code & knowledge base.

I'm imagining a raspberry-pi-sized FM transmitter in someone's bushes causing their (and only their) smart electronics to behave differently.

anyone know of some good books
like lets say top 5 books of all time in life to read lol

I just love knowledge and learning it doesnt' matter what kind of book I just want something to read that will help me learn and get more knowledge.

or something interesting and fun to help pass the boredom

it can be history,science, math, technology or anything really I just want to learn more and know more than the average human.

I want to be up to par with my fellow human beings so top 5 books of all time is greatly appreciated
Lying because you're afraid of an unreasonable world... That's your argument? Lying because of fear doesn't make it right. I think we fundamentally disagree on values and maturity levels that adults should aspire to.
I remember reading a webcomic where one protagonist brought this point forward, concluding that most worlds are simulated and thus we live in a simulation.

Yes that's correct.

I think of it just slightly differently -- 256 bytes, 2048 bits -- so 2^2048 (same result as your 256^256).

To give people (who don't spend time with these numbers all the time, I do b/c of cryptography): 2 ^ 256 is on the order of the /number of atoms in the entire universe/ -- every star, moon, comet, black hole, galaxy, etc. across the entire known universe)

Now consider this: 2^512 -- take every single atom in the universe, and imagine that that atom //contains a universe of atoms//. Congratulations, you're only at 2 ^ 512.

Imagine how large 2 ^ 2048 is!

Ah the "government" playbook.

Life does not work that way. If I want to affect change, I have to get the job done.

The "government" is you and I. There's no group of people up in the sky listening to our complaints.

How many of the people here complaining about Amazon being evil have even written a grievance letter to this "government" that is supposed to step in and stop Amazon from being evil?

People are voting with their wallets and they want cheap consumer products with a great return policy made by sweat shops delivered by people urinating into bottles barely making minimum wage after accounting for overhead.

Every single Amazon customer knows this and they don't care.
I always wondered wtf the browsers language setting is for. Can a website not query this for the preferred language rather than make a language decision based on an IP address geo lookup?

I am English, my browsers language order is to set English (UK) then English (generic). No foreign languages. However I live in [redacted] and if I visit a site it will give me a [redacted] version due to my location rather than the language set within the browser.

I (apparently wrongly) assumed saying I want content in English would mean the website would query what language the user wants and then send that.

Could someone explain what the browser language preference is for?
Then I guess you're the smart one. My apologies.
I find that "infinite as an endless process" concept intuitively very heplful as well. However, reading Gödel, Escher, Bach[1] showed me that there's another, more static logical interpretation of infinity which also comes handy.

In an infinite process, you can always take "one more step" to create the item after that. Let's assume there exists a "final" mathematical object that goes after every finite item in the generation process (i.e. it is higher than any item in the list, or smaller, or has happened after all of them)... This object doesn't really belong to the infinite generative sequence, it's an item outside all of them, and can't be reached by completing the sequence; it merely exist outside the process and happens to have the property of "dominating" all the items in it.

You can assume the existence in the same way you assume the existence of a number which is the square root of -1, or how you define triangles whose angles add up to more or less than 180 degrees. If you do that, this object "at the infinite" can be formally defined and treated axiomatically to find out what mathematical properties it possesses.

It's about incentives here i think.

For Jobs-era Apple, your incentive is to make something Jobs liked and the only reason that worked was because Jobs had great taste (subjective ofc) and a strong vision of what he wanted.

Amazon is very very focused on outcomes and that's what incentives a lot of decisions. Being data-driven is a tool to understand and measure the outcomes and inform decisions.

Google from the outside may be data-driven but data-driven to do what?

Jobs wanted to make a great phone, amazon wants to be your everything store, Google wanted to organize the world's information but the company has far exceeded that original goal and it's not clear what they want to do now.

That's what we keep seeing products that seem to exist for their own sake in many companies imo and those products struggle to find footing and die with no learnings.

I used to live in Germany and now I moved back to India (where I am came from)

Amazon atleast in India is better than anything else.

It's very difficult to source things which are not common place goods.

For example, if I want to buy 3 phase, 1 horsepower motor, 4 pole motor AC induction motor. There would be no websites who directly sell, and if exists then it will charge rediculous price.

Most B2B purchase in India requires going through IndiaMart, where you post requirement (that too can't upload photo, has very small description limit)

Then vendors will hammer your phone with useless calls, asking the details you already offered and no one really replies to text. They don't understand not everyone wants to be on call.

There are rediculous number of vendors who import from China and live around a port city and have goods stocked in their wharehouse, shipping all over India. And they lie about being manufacturer, I am pretty sure they aren't even inserting a bolt in the final product.

And either companies are too big where they don't care about a guy who wants 1 motor, or they are too small that they don't even know how to sell online.

Amazon expanded the available products which can be bought without BS at competitive rates but it too missed niche category stuff.

For example, I can't buy lithium iron phosphate battery online at the moment, few websites appear in Google but they ask you to contact them.
But does it tho?

I'm in Toronto. I used Foodora for the longest time because their delivery fees were great ($0.99 and no "service" fees). 6 months ago, Uber Eats seriously stepped up their game and I have been only using Uber Eats. The delivery fees on Foodora went up to $3.99 for all restaurants and their selection of restaurants are way worse than Uber Eats.
You're comparing apples and oranges. Your argument is that proprietary API's are better than Vulkan because there are less code paths, but if you go that way you need a completely separate code path for each top-level API.

I think you're vastly over-stating the complexity of handling this in Vulkan. For the ray-tracing example, realistically you have one branch for non-ray-tracing, and one more where you check for whatever RT extensions you need and do ray-tracing if you have them available. This is exactly the same complexity you would have with DX12.

DX12 Ultimate is a really poor counterpoint. No serious game developer is going to be content targeting only XBoxSX and PCs build for over $1200 in the last 18 months. Realistically, even if you only target MS platforms, you're probably even going to need a DX11 renderer, and the DX12 API is already quite different on XBox and PC, so that's already 3 code-paths minimum.
There was a giant banner at the top of their site that explained there was global health crisis and shipments of non-essentials could be delayed. They'd been asked (told in some cases) by governments and others to prioritize eseential product shipments, so they did. They also told suppliers to stop sending non-essentials for FBA. If they had capacity (and items on hand) they've been delivering non-essentials (I've gotten some of my stuff sooner too). There was a big article that blew up here about how France was going to fine them for shipping non-essentials/putting workers at risk and gave them 24 hours to change their entire warehouse workflow/technical systems (Amazon responded by saying they'd need to shutdown for a bit to avoid the fines as they reworked everything to comply).
Apologies, I should have explained it differently.

0.999... implies a number infinitesimally smaller than 1. You wouldn't use 0.999... in a hyperreal system because you can represent it directly.

I shouldn't have mixed different systems and claimed they're mathematically equivalent, you've proven that doesn't work.

It's not really a function generator without DC offset and proper amplitude control. I don't want to be overly negative, it's a cool project. I think there's definitely something to be said about having polished interface to a low end function generator. However, there needs to be more information on specification such as ENOB, sample rate, max Vpp, max offset and bandwidth.
