A little background: Through my teens in the 90’s I did a lot of the things you may expect. I was a script kiddie on mIRC, made a tank game in Unreal Engine, and did some Quake modding. From 2002-2004 I landed a job doing Java web dev, SQL, and overall database administration because my father’s friend needed someone that could do that. I was ok at the job, but not great. Being young, my hobby that turned into a 9-5 made me want to stab my eyes out and I quit.
With that said, I can understand a lot of what’s going on, but it doesn’t “click” anymore. I spent 20 years as a career machinist, but I physically can’t do that anymore. Here’s the rub - my twin brother is a brittle diabetic and can’t work (lots of other stuff going on as well), and our mother is getting old (father passed this year). The only reasonable way forward that I can see in order to be able to support my brother is trying to get back into development.
When I stopped, subversion was what we used. I’m trying to understand Git, but it’s a giant conceptual leap. I guess, what I’d like to hear from you all is a way to jump back in as quickly as possible in such a way that it may be a career.
Thanks
To piggyback, the true main difference is svn stores commits as snapshots and git commits are deltas from previous. This is why git is depicted as a tree since it’s inherently a node-based structure.
A git commit is a snapshot. The node-based tree structure is an artifact of recording pointers to other snapshots and labeling snapshots with a branch name.
You are correct. Technically a snapshot, but unmodified files are not duplicated from the previous. Imho that is one of the key things to understand about how git works ( and why rebasing and branch manipulation works so well)
