I think the purpose of life is clearly demonstrated by what it does all the time: resist and reverse entropy.

My claim as that we don't need to cover math before we tackle cryptography, and my reasoning is that there is more than one way to approach a topic.

Here's a discussion of cryptography that has 0 occurrences of "ring" (for example): https://en.wikipedia.org/wiki/Cryptography

> Part 1

> Mathematical Background

> Before we tackle cryptography we need to cover some basic facts from mathematics.

Nit: we really don't. This reminds me of how dry and uninspired the cryptography and cryptology (less so) classes I took almost 20 years ago were.

> but overall it performs a valuable economic function

Can you explain what that is?

> To understand this requires understanding markets very deeply

Apparently you aren't the only person on this forum who does. Are we just supposed to take your word for it?

Because you'll end up with pros great at cranking out un-maintainable MVPs.

Coming from mobile indie games, I was thinking ads (which I now realize steam doesn't allow) and mtxn. Despite whatever moral qualms people have with this type of monetization I can say there are many multiplayer games that would not be possible without them (or VC funding).

I agree that for most games, the difference in installs between free and not-free is many orders of magnitude.

> Coupled with the fact that I would have realistically grossed less than $4k

How many concurrent players did you have on steam? This seems low unless the only monetization you're thinking of is a purchase price.

> You can make a shitty game in one sitting using today's tools; I've done so a bunch of times. My games all suck but they are games with art, music, sound, and gameplay that people can play and enjoy briefly.

I'm skeptical but would be happy to be proven wrong. What are some games you've made that satisfy:

1. Made and published in one sitting

2. Have legally sourced assets and code

3. Have people who don't know you personally that have indicated enjoyment of it

If this is a regular occurrence for you, I'm curious about the level of experience that got you to this point.

> imagine if you built a restaurant serving food you get from Hello Fresh

Seems like a flawed business strategy. Ex: I currently use AWS, Linode, and Vultr for different regions and services for a single app. Avoiding vendor lock-in isn't trivial but is definitely something you can design for.

Any time I read an announcement like this I refresh my knowledge of competitors and make a mental note that it might be time to switch soon.

> It makes me think that the company exists just on a constant flow of VC or similar money and what I'm using or paying for isn't a realistic or future cost and I'm involved with a system or platform that is getting stretched larger and larger regardless of income and the more money they raise the harder the fall will be.

If you're an investor that's a valid concern. But as a user? I've been happy to have VC funding subsidize my food via Hello Fresh etc. whenever I'm inclined.

> Where do my Workers run? Don't know, don't care

Glad that works for you but for my game servers edge computing is not ideal and generally currently not even applicable.

This is a strange take that seems best described as "raciphobia". It's not "bs" to ask whether or suggest that a creative work was inspired by a stereotype.

There's the creator's intent which can't really be known. Then there's the observer's interpretation which is equally valid.

This makes me wonder how we went from Wright brothers to commercial flight. Despite being the longest Wikipedia article I've ever seen the Wright Brother's wiki doesn't seem to cover it. Maybe it's a poorly defined question.

Some people can't tell the difference between 17 ms of latency and 68 (4 frames at 60hz), while some can't bear it.

Overtime or another job?

If five fast food workers can prepare 100 meals in the time I can prepare 1, there should be some monetary savings shared with me (the customer) unless my time is truly worth close to 0. That's how economies of scale work.

Split keyboards can help with wrist positioning but not finger travel, both of which can contribute to wrist problems.

I use Dvorak for keyboards and qwerty for thumbs. Keeps them both in muscle memory to some extent, so it's not too painful when I'm using someone else's keyboard.

If you ever have non-deliberate anything in production there's a non zero chance you're doing it wrong.

Why does HN automatically strip "How"?

I agree in general that they're often misused, but "just" and "simply" do have a place. Specifically in place of "only" or "instead", or to set up a subjective comparison.

A: I'm going to do X, Y, and Z.

B: If you just do X, we'll meet the requirements.

A: I tried X Y and Z to fix my problem.

B: You can simply reinstall the IDE.

> China's Three Gorges Dam slowed down the Earth's rotation by 0.06 microseconds per day [2]. That's actually not a big deal because the rotation has variance all of its own from tides, weather, etc

I'm confused, how is the mean changing less impactful due to relatively high variance? If the was no variance at all, would .06us be a disaster?

So Apple's app review process never made it out of internal beta. That explains a lot.

> Just make everyone pay for not just their consumption, but also for the damage it is causing on top. Problem solved.

More like problem stated. Determining true ecological impact is not trivial even if you ignore all the perverse incentives.

One of the most important things we can teach kids today is how to teach themselves. I wouldn't have graduated college over a decade ago without Wikipedia and there are far better resources now.

Did the battery die or the whole phone somehow?

You and Feynman both: https://youtu.be/px_4TxC2mXU

Code and case summaries couldn't be much different. With code you get compile time validation, run time validation, (hopefully) test validation, and you can generally look at a block of code and say "seems like this should work" or "this makes no sense". You get none of that with facts of a case.

Are there server circles? I'd guess they talk about intel and AMD more than Apple.

> In the end, a hammer is a hammer. If it hammers well, what difference does it make how it got that precise shape?

"Hand made" has been a selling point since things were first made by things other than hands. Example: "The factory, known as the Ateller, [...] it is the place where our craftspeople assemble each BUGATTI by hand."

What makes it a copout? I've had friends choose the resign option. I've been fortunate enough that my resignations didn't involve ultimatums.
