Show HN: I'm 17 and wrote this guide on how CPUs run programs
Hi! I'm Lexi, I wrote this article/mini-book. There's a classic question of "what happens when you load a website?", but I've always been more interested in "what happens when you run a program?". About 3 months ago, I was really annoyed at myself for not knowing how to answer that question so I decided to teach myself.
I taught myself everything else I know in programming, so this should be easy, right? NOPE! Apparently everything online about how operating systems and CPUs work is terrible. There are, like, no resources. Everything sucks. So while I was teaching myself I realized, hey, I should make a really good resource myself. So I started taking notes on what I was learning, and ended up with a 60-page Google Doc. And then I started writing.
And while I was writing, it turned out that most of the stuff in that giant doc was wrong. And I had to do more research. And I iterated and iterated and iterated and the internet resources continued to be terrible so I needed to make the article better. Then I realized it needed diagrams and drawings, but I didn't know how to do art, so I just pulled out Figma and started experimenting. I had a Wacom tablet lying around that I won at some hackathon, so I used that to draw some things.
Now, about 3 months later, I have something I'm really proud of! I'm happy to finally share the final version of Putting the "You" in CPU. I built this as part of Hack Club (https://hackclub.com), which is a community of other high schoolers who love computers.
It was cool seeing some (accidental) reception on HN a couple weeks ago while this was still a WIP, I really appreciated the feedback I got. I took some time to substantially clean it up and I'm finally happy to share with the world myself.
The website is a static HTML/CSS project, I wrote everything from scratch (I'm especially proud of the navigation components).
I hope you enjoy and learn something!

Putting the “You” in CPU
Hi! I'm the person who made this thing!
Some backstory on me: I'm 17 and left high school a year ago to work full-time at Hack Club (https://hackclub.com/). I've been programming for as long as I can remember, and started homeschooling about 6 years ago to focus more on that (and my other interests).
Since I'm entirely self-taught, I haven't taken any college systems classes — and while I had picked up a lot, I wasn't happy with my answer to "what happens when you run a thing." So I let myself spend a shit ton of time actually learning as much as possible. What I found was that:
1. Operating systems and hardware are really fun to learn about!

Ask HN: Free Email Hosting for Nonprofits?
Hack Club is a nonprofit network of hackathons, student-led coding clubs, and open source projects. Our website is https://hackclub.com and our GitHub is https://github.com/hackclub.
We have been receiving free email hosting from Google Workspace and providing it to the Hack Club network, but we recently hit the domain limit (600 domains) on Google Workspace for Nonprofits. Each domain is typically a hackathon or a chapter at a high school.
Does anyone have any recommendations for email hosts that we could look into? As a mostly volunteer-driven nonprofit, we can't afford pay per-user pricing as there are thousands and thousands of accounts.

K3s Traefik Ingress - configured for your homelab!
But of course, I want to run a QuestDB instance on my node, which uses two additional TCP ports for Influx Line Protocol (ILP) and Pgwire communication with the database. So how can I expose these extra ports on my node and route traffic to the QuestDB container running inside of k3s?
