What do you work with (if you don't mind answering)? I'm looking for a change and like low-level stuff about as much as I like any other level. I've done some cycle-accurate NES emulation and VM implementation stuff - I'm not much of a DSA guy but performance and efficiency appeal to me.
I work with pretty much everything (except GPUs I guess). Embedded is extremely relative. To some, embedded means a rack mount server that's idk embedded in a vehicle instead of a datacenter. That's not me. To others, embedded means a 4-bit low power, mask-rom fed micro inside a sensor IC. That's also not me.
So I work with microcontrollers of various vendors, I do FPGA with hard and soft processors, recently did just past the smoke test through embedded Linux on a SoC, and I've done plenty of desktop code on Linux and Windows for interfacing. I get to work with a wide range of devices and a wide range of tasks for them. Might not pay as much but my goodness is it fun
I couldn't make head nor tails of the QBasic help back in the day. I wanted to. I remember reading the sections about integers and booleans and trying to make sense out of them. I think I did manage to figure out how to use subroutines eventually, but it took quite a lot of time and frustration. I wish I'd had a book... or a deeper programming class. The one I had never went further than loops. No arrays, etc.

It's an amazing problem! I haven't spent much time on it - maybe 20-30 hours spread out over several years - but it _is_ something I come back to from time to time. And it usually ends up with me sitting there, staring at my laptop screen, thinking, "but what if I... no, crap. Or if we... well... no..."
TBH it's one of the things that excites me, because it makes it clear how far we still have to go in terms of figuring out these planet-scale physical processes, simulating them, deriving any meaningful conclusions, etc. Still so much to learn!
My kid hated school in kindergarten as well. As did I. I didn't get any kind of intervention, and I feel like that set me on a terrible course.
My kid, mercifully, was diagnosed and received intervention in the form of tutoring, therapy, that sort of thing. He still has weapons-grade ADHD, and his handwriting is terrible (dysgraphia), but he seems to have beat the dyslexia and loves reading almost as much as his mother and I do. He's happier, healthier, and has a brighter future.
I really, really hope your friend comes to understand, somehow, that their kid needs intervention, and will benefit tremendously from it.
I come to HN because there are absolutely wonderful discussions in the threads. Not always, not consistently, but often... the sort of conversations (even sometimes arguments) that leave me feeling energized, better informed, and/or fired up over some new project or technology I'd never heard of before.
That said, equally often I feel like a hermit who limps into town every couple weeks, wild-eyed and twitchy, and listens to other people's conversations, smiles and nods, maybe says something friendly and innocuous, and then I notice that there's a circle of people gambling on street-fighting urchins or chanting "ass-to-ass" at some degrading sideshow, and I have to haul my ass back out to the sticks before I'm found out and my blood is ceremonially drained to inaugurate some hellish techbro kegger 'n' orgy.
This has to be the best comment I've ever seen here. I feel the same way sometimes.
Luckily there is more good than bad, so I keep coming back for the A+ conversations and knowledge.
VistA is an old system, and it's definitely "aging." But the thing is that it actually works really, really well. For instance, it kills a remarkably low number of people, which is one of the benchmarks I personally value in an EHR.
One of the interesting things about this is that, from my perspective, VistA's sort of a mesh of servers rather than the hierarchy we might expect from a federal system. Perhaps that's because of the complex interplay between federal and state and local laws. But anyway, there's probably a "station" for VistA near you that serves your area, and that's very similar (though not identical) to the "station" in the next neighboring area/metropolis/state/whatever.
But weirdly it seemed like the plan to roll this out was to replace all of the functionality at a given VistA station, rather than to do a strangler fig sort of thing and work on supplanting VistA's functionality in a specific functional area (whether locally or nationally). I don't know if that's because of the aforementioned complexity of laws, or the complexity of how the system(s) is/are administered, or other reasons that would elude me.
VistA EHR works reasonably well for end users but the problem is that the underlying platform is kind of a dead end. There's no practical technical path to keep it moving forward with major new enhancements (some of which are legally mandated for compliance). Hardly any developers have the platform skills, no one wants to learn (career suicide in most cases), and modern tools don't support it. It's a shame but that's the reality.
I don't disagree at all (disclaimer: I don't work on VistA, but systems that communicate with VistA... close enough that the "career suicide" phrase hits a little close to home).
I think the bigger problem is that we're not meaningfully grappling with the reality of what it takes to replace legacy government systems.
Another grain of sand on the beach of things that we're completely unequipped to deal with, I guess.
I third MathAcademy. I graduated high school >25 years ago with almost no math skills and had a major struggle with the math prerequisites for my CS degree ~15 years ago. I've been wanting to get into higher math recently, so a few months back I started hitting MathAcademy heavily. Its structure and modularity is exactly what I needed.
> Its structure and modularity is exactly what I needed.
Through great effort, I completed Mathematical Foundations I & II. I talked about it a bit here [1][2]. If you read through MathAcademy's methodology and reasoning, it's incredibly strong [3], but in practice I never felt confident in my understanding or execution, everything felt quite discrete and I didn't understand the relationships or purposes of what I was doing. I kept going because I was getting better, and because people online who were quite good at math said not to try too hard to understand things fully at first, since the abstraction level of math is so high.
The weeks before finishing MFII, my motivation was higher than ever. The day I finished, I felt nothing, and in the following weeks I decided that it was time to let it go for now.
I think MA is good. I've never done so many exercises in my life, and although I wasn't super confident, I was far better at math than I'd ever been. But I think MA probably needs a lot more multi-part exercises so you understand what you're doing and where to use things. I feel like I learned "Discrete Math", but in the sense that all the lessons were discrete and I couldn't draw connections between them.
(I'm actually set to complete Mathematical Foundations II next week, after completing Mathematical Foundations I recently.)
Thank you for your comment. I had a very nontraditional path to engineering, even in an era of self-taught programmers, and I feel a lot of pain and despair and bitterness and, uh, a vicarious feeling of disappointment, I guess... so discussing this sort of journey does me some good.

Very reasonable takes. I think you're spot on. I do have a lot of trouble with the abstractness and disjointedness of it. I'm hoping that repetition will improve it. So far I'm still struggling with the same things I struggled with in college - combinatorics, for whatever reason, just seems to slide right out of my brain.
By "modularity" I meant that I could squeeze in 10-15 minutes here or there without having to commit multiple hours to a single concept, and that I could take a day off without destroying anything, but that's probably connected to the "discreteness" you mention, without a holistic, oceanic kind of cohesion or connectedness.
I'm actually working on a project now, an educational site that's kind of along these lines but focused on areas of CS I've always struggled with - Lambda Calculus, Type Theory, Lisp, that sort of thing. I think I have some good ideas. I hope I come up with more, because I definitely want to build a rich mesh of knowledge rather than a catalog of disconnected facts and tools without any underlying meaning.

Hi, I'm Nate. I'm a generalist backend/infra/system kinda guy with ~14 years of experience. I love where I'm at and what I do, but I intend to move to France in 2028 and that's an impossibility with my current employer, so I'm exploring other opportunities.
I'm spending a lot of time outside of work tuning up my math skills with the eventual goal of getting a PhD in Complexity Science, CS, or pure math. Careerwise, I'd love to get into HPC or MLOps/AI/ML research (not necessarily GenAI).
If you're seeking a stable guy who'll grow and develop with your organization (I've never been employed less than four years), I might be the guy.
EDIT: Nice, got a scam email... en français. Thanks for the opportunity to practice :P
I tell it to accomplish only half of what it thinks it can, then conclude with a haiku. That seems to help, because 1) I feel like it starts shedding discipline as it starts feeling token pressure, and 2) I feel like it is more likely to complete task n - 1 than it is to complete task n. I have no idea if this is actually true or not, or if I'm hallucinating... all I can say is that this is the impression I get.
