I'm only suspicious if they don't simultaneously and eagerly show me their Github so that I can see what they've accomplished.
Sometimes this industry is a lot like the "finance" industry: People struggling for credibility talk about it constantly, everywhere. They flex and bloviate and look for surrogates for accomplishments wherever they can be found. Peacocking on github, writing yet another tutorial on what tokens are and how embeddings work, etc.
That obviously doesn't mean in all cases, and there are loads of stellar talents that have a strong online presence. But by itself it is close to meaningless, and my experience is that it is usually a negative indicator.
But if you mostly mean in the sense that they don't have a fancy GitHub profile with a ton of followers... I agree, that does seem to be the case.
LinkedIn on the other hand... I sincerely can't imagine networking on LinkedIn being a fraction as useful as networking... Well, at work. For anyone that has a decent enough resume LinkedIn is basically only useful if you want a gutter trash news feed and to be spammed by dubious job offers 24/7. Could be wrong, but I'm starting to think you should really only stoop to LinkedIn in moments of desperation...
there is an entire industry of devs who work on meaningful projects, independently or for an employer who solve amazing problems and do amazing sh*t none of which is public or will ever be public.
I have signed more NDAs in my career than I have commits in public repos :)
I'm younger, but not new to programming (started in the early 2000s.) Mentality-wise, I like working on software because I like solving problems, but I only really do a day job to make a living, not to scratch an itch, so I continue to work on software outside of work hours. I basically don't care what happens once my software reaches the Internet. I publish some open source software, but not as a portfolio; just for the sake of anyone who might find it useful. I don't really advertise my projects, certainly don't go out of my way to do so.
I basically have GitHub for roughly two reasons:
- I use a wide variety of open source software. I like to fix my own problems and report issues. Some projects require GitHub for this.
- May as well take advantage of the free storage and compute, since everyone else is.
Honestly, my GitHub is probably a pretty bad portfolio. It is not a curation of my best works, and I disabled as much of the "social" features as possible. It's just code that I write, which people may take or leave.
Earlier in my career maybe I cared more, but I honestly think it's because I thought you were supposed to care.
I have worked with some stellar programmers from many different places, probably more than I really deserved to. I don't know for sure if any of them didn't have GitHub accounts, but some of them definitely did have GitHub accounts, barren as they may have been.
