"Old crusty people refuse change and to continue learning."
Now be nice.  . You also seem to be a bit bitchy this morning. There was no intent to start a cat fight.
My question was serious, as all of the articles extolling the virtues of GIT vs. SVN leave me picking my nose and pondering their argument. Old crusty people tend to run development groups and what not, so before fragging the dev process, there needs be justification.
My post was not a GIT sucks question - I actually have only tinkered with it. Since VS2*** has buried it into the menus and behavior, I thought I might learn something.

You're right, I swear it wasn't you or your post. I'm just holding on to crap from a ton of bad experiences on CP.

All I care about is source control and the release process. Trying to understand the next great thing.

As a former user of SVN and VSS the difference for me is that its branching model makes it much more (but not perfectly) clear what's going on and where my branch fits into the project, and not having to deal with locks.
And I must say Visual Studio's git interface is the bee's knees and one of its best features.

I personally felt that branching and merging, accompanied with reviews in one toolset like git hub is way better than SVN.
But to be honest, I haven't looked into SVN for at least 6 years and even back then i did all relevant things with JetBrains tools, so i only have to use SVN to push and pull code.

Branching is much easier, it does not create any additional directory since it is a pointer to a specific commit. The way branches are managed make following the timeline of modifications a lot easier for merging purposes.
We used it for an ECU with a main codeline + different features to be added + different parts of the code to be ported to another OS + different stages of development for every customer. Managing that amount of branches with GIT is easier. EG tyipical workflow in GIT was:
* branch from current main or current stable (first thing I do before touching the code)
* get a feature to develop from Jira / Polarion / Redmine
* Start developing the feature
* [...] Several commits and pushes
* Eventual side-branches for different potential solutions / potentially breaking code changes
* Commit "working solution"
* Pull request to Integration
* Branch from current main or current stable
* Get another feature to develop
* Repeat as necessary.
Integration will then merge all open branches in the new main or stable line and stop + reject PR if some branch causes failures to compile, otherwise regression tests and validations are peformed and main or stable is advanced. Now everything shall start from main again.
For one developer it's useless, for 4 developers in the same office it's overkill, for 300 developers across the world it's sanity. Nothing ever gets removed from GIT, ever (unless some idiot with permissions forces it) so a stable, working commit is always reachable.
One thing I loved about git was that it doesn't need a server, any file-system works, so when I worked for B***h I actually cloned the repo on my network, worked locally from my PC to the local repo then send only the vetted commits to the company repo. It allowed me a lot of flexibility, mostly that of using my own computer to edit the code while I would have been mandated to use only their horrible workstation with only a handful of useless programs (writing code in Keil is painful).
In my current company we use SVN, we are literally 5 developers in a office and SVN is also used as a shared storage for documentation and stuff that should not be there. Many systems in the company refer to that SVN so we won't change - except that we can only have a total of 20 users otherwise we'd have to change license for the SVN server and we actually are at capacity since there are (stupidly) other people accessing that repository, and we can't have more than one repo due to licensing.
Any serious company still uses some form of server for GIT anyway for permission management (you don't want to give rebasing permissions to any developer unless you want a broken repo).

We do all the branching / dev / commit / merge to integration just fine with SVN. I simply fail to see the superiority of git in this regards. But read my comment to the entire thread.

Okay, based on Jeremy's and other comments, I think I may be close to understanding what GIT does better than SVN or any other centralized server system...
When a developer wants to do work, they pull a working copy. It's local to their machine. All of their work - commits and what not occur to the local copy. The changes do NOT go back to the repo until they push. When they push, the code changes, the history, etc go with the push.
Do I have this correct? Going to go read some GIT doc.

Oh, I'd also add to that, that in git-land, to help untrusted code not make its way into the mainline and since merges happen like crazy (a good thing), a pull request is a common thing. So, if someone pushes a change to a remote repo, you could set it up to require a code review. You can technically do this in SVN-land, it's just more of a pain to pull off.

Sounds like how I work.
I tool away for a couple of days; if I was on the right track, I compile, zip and save that version to a remote drive with a dated file name. Or start over.
Repeat evey few days.
No branches, twigs, leafs, buds, flowers, weeds.
Sort of like how we did backups in the "old days". Except there are no carts with card trays or portable disk packs.

For one man teams that are diligent, it can work. When you get to more than one, it rapidly gets out of control.
I still remember the day when I was cleaning up the project folder... and I purged all the versions. I had no idea. He almost had an aneurism... took a few deep breaths and explained to me why he had a twitch in his eye  It's not like I was on a mission, I was trying to help free up some disk space we needed...
So, there I was with this "I just took a bite out of a ****-sandwich" on my face. Took a deep breath and said, "let me pull the backup tapes..." Thankfully they were from the day before and good. This was the day I had a career epiphany - delete nothing. Move it, archive it, but delete be bad.

I am not a big fan of Git but that's what we use. I guess the good news is GitHub is not the sole provider of the service - there are others such as BitBucket which what we use and it integrates with VisualStudio reasonably well.

See that's the other thing. I would NEVER have company code out on GitHub. Source code is the Crown Jewels and the jewels stay on the premises. I do know you can set up your own server locally, or I think I read about that.

GitHub does allow for private repos btw. If that's the concern. I mean, the code is still on their servers though, but at least it can be marked as private if desired.

Github is not just public repositories, it makes most of its money by hosting private repositories.
You can use other services like Azure or Bitbucket.
Or even self host.

sorry. Microsoft bought GitHub in 2018. Microsoft is the "most public" fluster cluck of security that I can even imagine, not that they are alone. I'd not trust HP nor Amazon with the Crown Jewels.
I want that one person or small group in my company understanding they are not going to lose a contract, they are going to be summarily terminated for not doing their job.
It's down toward the bottom of the list to research - offsite GitHub repositories, but every fiber of my being says no. If I could put a private GitHub repo behind my firewall and on my network - fine. Companies hosting this out in "the cloud" are out of their elephanting mind.

You certainly can - I have a Git server on my Synology NAS as a local backup, and I've had a locally installed instance of Gitea in the past.

The origination of GIT was specifically aimed at online open source projects.
Git - A Short History of Git[^]
The only significant problem I have encountered with git is that it does not work well with Enterprise development.
In an ideal Enterprise world one would have the following
- Strict boundary breakdowns
- Teams working on libraries
- Applications using libraries by version
For git the above works well because a library is then just a repo. And a deliverable.
However that ideal is not what happens. Even modestly sized business multiple applications (product or service is still an application) are a norm. With SVN that works as follows.
- library code goes into its own folder tree
- Apps each go into their own folder
- An app folder and associated folders is labeled for a build.
The means that the library code moves forward but it is labeled independently for each app.
It is NOT possible to do the above with GIT. There is one label for the entire repo.
So one often ends up with a mix of idioms. Perhaps one library in its own repo. But other libraries might be copied. Or two or more apps end up in the same repo.
And a repo explosion without tracking can also occur. Where one offs end up in their own repo.
With SVN it would just go in a new folder. Of course people will complain that that last case is a problem. So it is. But creating new GIT repos every single time without any coherent tracking is also a problem. (I have seen developers create repos just to experiment and then the repo gets abandoned.)
---------------------------------------------------------
As for losing source control due to problems with a specific source control solution ...
Long ago losing databases was also a problem. Forums would always have someone asking how to restore corrupted databases. That was true for every database vendor. I haven't seen anything like that for years. But also true that now people always back up their databases.
Source control is NOT a back up. But many places treat it has such. Even now.

I am hoping the use of sub modules will solve this.
One repo for the Solution, it just tracks all of the other required repos (libraries) at the needed release levels.

"source control is not a backup"
true words. But I have it on IT's assurance that they are imaging the VM server hosting our code. Years ago, I submitted an IT ticket to verify our backups. This created a tornado of panic. What do you mean the backup is bad? No, I asked you how do you know it's good.
As for your other comments about libraries and common code bases, well I gave up on that 10 years ago. ctrl-c/ctrl-v is our inheritance process  I'll admit that we're a very embedded product oriented shop, but I'd still like to see common code isolated to one area. Like I do, but I lost that battle long ago.

I like to point that out when someone complains because I insist the find the license. That due diligence comment really makes C level execs perk up.

" copyright violations?"
Please elaborate, I'm not following you. All of our code belongs to us.
As for your description of enterprise level development, holy cow, I've not done anything like that in 20+ years. Thinking back to when I did gave me a headache
