> Solely moving assets within the system does not create growth of the entire system.

This is completely false. As I've pointed out elsewhere, the possibility of trading existing assets means that one entity (say, a farm) can produce more of a good (say, rice) than it can directly consume. Without exchanging goods, this would make no sense, specialization of labor would be lost, and the production of all types of goods would crater.

I don't care about the which-language-is-best-to-start-with debate that is being argued in full force here. If you want to rails, knock yourself out. If you want to JS, woo! JS!. I care a lot about seeing your potential employer as an antagonist. They have just indicated to you that they like you enough to invite you to join them. Negotiate, sure, but assume good faith. And the very idea that they were waiting for a better candidate who didn't show up undervalues you. YOU were the one that impressed them most. How well you code was only a part of their choice. They liked your personality best, too, and your honesty, and your dedication, and that indefinable other thing that's hard to quantify.

They are likely the good guys, and they see you the same way. Now go ask for a better salary, or more vacation, but don't assume the worst.

If software has any unique characteristics it is how far a single math-oriented programmer can get due to our unique abilities to pull down huge libraries with incredible functionality without having to work with anyone to do it.

Right. Even if you are unable or unwilling to play those political games, you can stop at the senior SWE or equivalent level at Google/Facebook/Amazon and still have an income that's well into the top decile. I'm not aware of any other field where you can get that kind of compensation without management or leadership responsibilities.
It's more complicated than that, even with very simple models. Consider the toy model where there are two types of talent, "A" and "B" and that society benefits roughly equally, but sub-linearly, from productivity added to "A" talent jobs and "B" talent jobs. Consider the following talent distribution:

A | B
--------------
Men |1 | 2
Women |2 | 2

As society tends towards the maximally efficient it will tend towards women in all A jobs and men in all B jobs, despite the fact that women are just as good at B jobs.

This obviously is a toy model, but it shows that even very simple assumptions can lead to very odd outcomes.

Ask HN: Why am I so unhappy in spite of material success?
I am in my mid twenties working at a prestigious tech company. I earn almost 5x what I did out of college 4 years ago. I have a very short walking commute. I don't work long hours. Objectively, my actual work is rather interesting from a technical perspective. I am in the best shape of my life. I take around 5-6 weeks of paid vacation per year and travel to interesting places.

In spite of all this, I wake up every morning dreading going to work, and I feel that my life has no meaning or purpose. I am constantly unhappy because of this. Why? How can I become happier?

I'm not sure why you're being downvoted without comment: that sucks. I think the fact this project can show per-node costs of the plan is interesting---and certainly a killer feature---but I think it's only part of the story. I think the structure is just as important.

Unfortunately, flame graphs don't show (much) structure.

Now, as a second note, I do a lot of performance work (systems programming in stacks starting at hand-assembled machine code, working all the way up to scripting languages). Personally, I find flame graphs not as useful as a traditional (inverted-)back-trace. I think the structure encoded in a traditional (inverted-)back-trace tells you a lot about poorly designed algorithms and bad systems interactions in a way that flame graphs (mostly) erase.
I think you're being downvoted for other reasons than your point. I think your point is STEM isn't really in the "high-risk, high-reward" category as is offshore drilling or underwater wielding but is compensated much more than the former.

Betting on bitcoin is as risky as becoming choosing to be a starving artist with the chance that one day you'll be the next James Pollock, and as Su. et. al pointed out (cited in article), women are the majority in creative fields. STEM requires a different explanation than "high risk" because it isn't.

Video stream with Node.js and HTML5
Yes. The first standard for securing computer systems mandated some protections against this. They were partly made by Paul Karger who invented the compiler subversion Thompson wrote about a decade later. Most just focused on that one thing where Karger et al went on to build systems that were secure from ground up with some surviving NSA pentesting and analysis for 2-5 years. Independently, people started building verified compilers and whole stacks w/ CPU's. They were initially simple with a lot to trust but got better over time. Recently, the two schools have been merging more. Mainstream INFOSEC and IT just ignores it all slowly reinventing it piece by piece with knock offs. It's hard, has performance hit, or is built in something other than C language so don't do it. (shrugs)

This isn't Elon Musk-style evil AI. This is the more prosaic idea of hackers being able to hack AI systems. For instance, a hacker can put stuff on a stop sign (which won't be visible to humans) to make a Tesla car think it's not a stop sign, and therefore cause an accident. I recommend reading up about it. This is the kind of stuff that can actually happen today.

The reason anyone cares is because we want static and yet flexible typing. The better a type system understands covariance and contravariance, the better it can be at statically checking complex relationships.

Why didn't the same thing happen in math and engineering fields? Are we really supposed to believe that women entered the medical field in vast numbers because the medical field rapidly became much more welcoming of women? Do we really believe that women didn't enter engineering fields, as they have done in medical fields, because of widespread discrimination everywhere in North America?

Nix is a package manager. It can be installed on many GNU/Linux systems or even on non-Linuxes, such as macOS.

However personally I found it limited to building software (nix-shell for reproducible environments and building images), and weird to use for desktop stuff. It was just weird to have two package managers competing. Maybe someone has some neat ideas how to make it work, but I just went to NixOS.

NixOS is a GNU/Linux distro that uses Nix, and leverages it to build the whole system configuration. There, you have generations, right in the bootloader, and can boot to any of those. Which is extremely nice, as I had just stopped to worry before upgrades. If they fail (unless they break the bootloader, which is quite unlikely), I can just roll back to where I was.

Installation is performed from a shell session and requires some knowledge about how GNU/Linux works. Just like an, e.g., Gentoo or Arch Linux. Essentials are all covered in the manual: https://nixos.org/nixos/manual/index.html#sec-installation and examples of the rest (desktop environments, etc) can be found online.

Nix/NixOS may be not best in terms of UI/UX/user-friendliness (some stuff would look weird, until you get used to it - guess it's the same with any unfamiliar tech), but I have an impression that community there is very nice and very helpful (and maintains a lot of useful documentation).

I haven't used Guix or GuixSD, so can't comment about it.

tl;dr: I went with installing NixOS on a separate partition, and mounting my old /home there. No regrets and not looking back. (Whenever I need Debian or Ubuntu compatibility - e.g. build a .deb package, I just do things in a debootstrapped chroot or in Docker)

Agreed, and thanks. It's clear that dropping panel costs really wouldn't affect the installed bottom line much.

I just focused on installation costs, which in all cases seem far less than 50% of the overall system cost. This suggests that there isn't much economic leverage in reducing (or preventing growth of) installation cost, either. Only in the large battery cases is there a single component (the battery) that dominates other cost components.

>which currently use a ridiculous amount of electricity to process somewhere between 2 TPS to 20 TPS.

The electricity consumption is a result of the mining subsidy, and artificially high fees from block space constraints, not fundamental costs for transaction processing.

If you break down the necessary costs (storage, bandwidth, CPU cycles for verification), it's actually very low, at about $0.001 (a tenth of a cent) a transaction:

https://bitcointalk.org/index.php?topic=3332.0

The mining subsidy is a fixed cost that will decrease in relation to the total number of transactions as transaction volumes increase.

Nah. You can use another service if you feel that the 10's of thousands of nodes somehow don't have a better understanding of the constraints of running a node than you. No-one is holding a gun to your head. Ever heard of Bitcoin Cash? Perhaps that might better suit your needs.

These sentences combined illustrate the difficulty of calculating a single accurate and representative measurement. Probably the following summary (mine) is better than nothing:
