Well, at this point, I don't even know what to learn for getting an entry level CS job...so C is it. Reached chapter 17 of K.N.King's C99, maybe read a little bit of C2x and C2y specifications, then I'll probably start reading John Calcote's Autotools and then metalanguage99. And I bet they won't help me for my early career in any way or form.
I've not worked since the end of Jan 2023, and that was a crappy internship with low salary for which I didn't get any "certificate" or proof of claim. I've graduated almost two years ago with no job. Half-assed my way over libvulkan to create a simple 2D engine, didn't learn shit. Did some open-source contributions to GitLab with Ruby, that also didn't benefit me, because contributions have low value in CV, and recruiters don't seem to give a fuck. Also maintaining a few packages on Guix atm, but no one probably cares about Scheme. Did a few low-quality projects on ExpressJS, NextJS and Svelte.I haven't applied anywhere because I have failed take-home tasks on Flask/Django/other mainstream framework miserably, and it has tanked my confidence. Rest of the so-called interns are scammers demanding that I pay them to work. Yes, you read it right, not paid work, pay-to-work. The job market has still not recovered.
Damn don't talk yourself down like this, maintaining guix packages is cool as hell. It doesn't matter whether your internship gave you a certificate, it's work experience on your resume.
