Does anyone else here participate in the selfhosting hobby without a formal IT related education or a career in a similar field? I’ve only had one or two programming courses as part of my university education, but it was only very basic Python and C. I’ve never formally learned how to use containers, version control or anything else. Sometimes I regret not pursuing an education in IT/programming because there are so many things I’d like to accomplish but can’t (for example if there’s a feature missing in some project, or to feel safe in my abilities to harden my servers and my network in order to expose services to the open internet).
I have my academic bachelors in CS and I’m doing a civil engineering masters on the CS track. So I’m the opposite of your target audience, but I did want to mention something.
Yes there are some fairly technical things like cryptography, natural language processing, and compression algorithms where you will need a good understanding of mathematical subjects like linear algebra, statistics, and group theory.
But apart from subjects like that, you can definitely learn most of what we did at the same pace, or even faster (and even then, something being difficult doesn’t mean it’s impossible to learn). You can easily find good resources online to learn languages from Haskell to C. Nobody is stopping you from buying books that are used as course material. Same goes for networking.
Saying all that, I never even learned to work with containers or VMs as part of a uni course. Most of the stuff we learn is in the realm of theoretical computer science. So I probably learned a lot about self hosting the same way you did: the internet and some friends.
I have formal education, from 1997, which serves nothing for the kind of technologies we’re using now. Even though I work in IT (call center) I’ve had to read a lot on networking to make sense of what I wanted to achieve. I also don’t know anyone else in my office that does this so I’ve been relying on online communities and my failures. I’ve learned so much by failing.
I’m a welder-turned-health and safety manager. What I’m learning from self-hosting I’m using to make our h&s reporting more efficient than it was before.
Closest thing I have to a formal education in IT is taking keyboarding, QB, then VB in high school in the early 00s. The only thing I came away with from that was the basic concepts; variables, integers, strings, loops, functions, recursion, etc. I remember nearly nothing about VB. Self taught some Python after that, went to Linux and started learning Bash, CLI tooling, editing confs, working on small portions of languages I didn’t know like Haskell (Xmonad) and eLisp (emacs), running containers… Long enough ago I remember manually setting up Apache and MySQL a few times, editing whatever init system I was using to ensure they started, etc.
Time and cost are big determining factors. Sometimes I’d like to know more but never enough to become indebted to educational bills for something I’m not making a career out of. Same reason I can install, remove, rekey and pick various locks, and have installed some access control stuff in the past under an employer, but I’m not shelling out to become licensed Locksmith or Security Systems Technician myself. Tools are comparatively inexpensive, and I have many from past employment, and YouTube is still free and archiveable… add in a bit of “dorking” to find manuals and whatnot and self-teaching just makes more sense for me. Same reasons I’m entering my shade tree mechanic arc these days - it’s not worth paying to become an auto tech but it is worth saving thousands on the repairs I can do. Plus it’s just fun to learn and work with my hands.
Yes, i would never work on computers for a job. I am too strongly a PEBKAC.

Yes.

I’ve thought the same for most of my life, but right now, not so much. All of my friends in the field are being laid off.
Just got done studying for an AWS cert required for my job. It was 150 bucks and an absolute waste of my time. Do not envy us.
I’ve managed to land on my feet with a new career that’s not related to IT but yes it’s a blood bath right now.
I’m gonna speak generally and it doesn’t quite generalize. Sue me.
Formal education in computer science is a waste, unless you want to be in academia. A formal education in computer science will either prepare you for higher education in Computer Sciences, or it will drill into you some best practices on how to be a good programmer. You can get the latter through brute force for free.
That said, I have a formal CS education. It has helped my career 0. I’m 10 years into my career and am the 1 man cybersecurity team (plus my boss and my coworker who does most of our networking stuff unless he’s too busy, then that’s me as well) for a fleet of ~4000 devices across ~1500 folks.
I have never once needed to explain to someone what von Neumann architecture is, and how it differs from Harvard. I have never once needed to explain two’s compliment or how to represent negative numbers in binary. Knowing what an xor swap is and why it’s used has only helped me solve a leetcode problem exactly ONE TIME. I have explained to many people what P vs NP is (no your suno track will not be the next cultural phenomenon) but nobody cares.
The stuff that did serve me was like, making the card game of war in Java. Even the GUI. That’s a project I would have never done because who TF would. But it forces you to implement recursion (war within a war), it entails some good validation checking practices, etc. the truth is though, I did not need a college education for that project.
At the end of the day, technical projects teach technical skills. Not PowerPoints based on textbooks.
If you wanna learn how to harden your servers, I recommend freemium hands on learning platforms like tryhackme or hackthebox.
Hack the box has a module on server hardening. It’s my go to for hardening servers. Happy to share the bullet points. It’s not too much. Basically just disable root auth, disable ssh except key-based, enable MFA (I use authelia) and you’re harder than 90% of boxes in the wild. Then just setup Fail2ban and you’re more or less golden for a home server.
I will take your advice to heart.
Nothing about my IT or software career has changed anything about my set up, except maybe some of the OS hardening info, which could be easily googled.
No need to gate keep, we kill google one laptop at a time :)
I personally do have a degree in computer science, but I feel like I would be doing this anyway, even if I didn’t. My degree didn’t teach me how to self host
Yeah, I studied linguistics and literature… Somewhere at the end of university I was presented to Linux and began my journey with computers. Bought a pi in 2012…used it as a media server … one thing led to another until I was able to build a debian server with 20 containers.
You write “participate” which sounds like a free choise, but I don’t do it out of my own free will. I do it because the web is so enshittified, that it forces me to selfhost more and more of my own websites that only I use.
I fucking hate doing any devops. I think it’s the most boring, soul sucking task there is. Fucking yamls and .env and config files in different places for every app with it’s own syntax.
I tried passing it to an LLM but it’s always subtly wrong, so in the end I still have to read everything, correct everything, generate keypairs, configure something on each client etc.
Every day a million bots are hammering my services, so I have to run crowdsec and fail2ban and make sure there are no ways in, everything is behind a login, up to date, constant manual migrations to newer versions cause one of my hunders of apps always has a breaking change.
I’ve written more devops and security related stuff on my CV than my carreer programming experience. I got a job because now I am not just a fullstack developer, but a fuller stack devsecops-veloper. Showing my homelab and docker setup during a fucking java + react interview landed an immediate yes at the wage that I wished.
I fucking hate devops. Now I have to do it in my free time and at my job. Why does the world force me into devops? Please take it away. Let somebody else handle it. I want to enjoy my life again.
/notsarcasm
Does not sound like you would enjoy NixOS, or perhaps it would be perfect. Everything is done by config.
I’m a social worker. I have yet to find another in my field who does this, but I’m always searching. When I find them, I’ll form a joint practice with them. With our powers combined we will take over the world.
I’m not a social worker, but I am interested in world domination. Can I join?
Yes, all self taught. I do some script writing in my job but it’s mostly mechanical engineering. I’ve had lots of people assume I work in IT.
I have no formal training but have been in IT for over thirty years.
The IT way
Bachelor of science in molecular biology here. Never had any computer/programming courses, not even in college. I come from a 3rd world country, so our “computer lab” naturally had two desktops that we were only allowed on for half an hour a week for basic windows tasks. I’ve always been a curious person, though. Moved to the US in 2010 and started messing around with a laptop I had that was struggling to run windows. Ran into this thing called “Linux” and the rest is history.
I’ve had countless sleepless nights fixing things on my broken Linux installs and/or to make some things work. That is the thing that built what I know now.
Being the same curious dude I am, I wanted to dip my toes into self-hosting, and I just discovered that it’s just a whole new world that is even more fun. Been doing things in this realm for around 1.5 years now and still dabbling.
Edit: forgot to mention that I now work as a software developer at a big company. Yes, my microbiology degree is sitting in the drawer sleeping. lol
