Had to implement a globally unique ID generator that would work in distributed/disconnected system for a project in TS today. Doesn't warrant an article (I think??), so here it is if anyone wants it. Much like YouTube IDs, etc. the result is in base62 to keep it as short as possible. Runs fast enough to generate 100,000 IDs in 340ms in a WSL environment.
Big ol' edit: Made this a tip/trick. Nothing to see here now. La la la.

Ooooooooh, wait. I see it now. Um, it's been a while since I posted a new article, as you can tell.   Thanks.

Of course it does...
Low-code tools boost developer productivity[^]
"Over 90 percent of respondents to a new survey say that low-code tools have boosted developer productivity in their organizations. 43.5 percent of developers are saving up to 50 percent of their time when they use low-code tools on a project."
I keeping thinking one of these days I will actually find an organization that actually measures developer productivity. Or devops. Or IT. Or DBAs. Or CEOs.
Now Sales ... those guys have it down ... 'how many contracts did you sign last month?'
But back to the article ...
""Low-code software has real value in democratizing software development to include non-developers," says Jason Beres, senior VP of developer tools at Infragistics, and creator of App Builder software."
Any one want to guess what Infragistics sells? Come on - I dare you.
The 'story' is based on a study created by ... bet you can't guess!
"The full report is available from the App Builder site."

I mean, I hear what you're saying.
But allow me to play devil's advocate in defense of low code tools at least.
Good ones are gold. SynthMaker (now FlowStone) is absolutely amazing. It was used to build Audio VSTs but is now an entire industrial automation creation tool. It's really well designed, and doesn't limit you strictly to its framework, which is extensible.
As far as productivity, I'd be interested if someone commissioned research on studying HOW to measure developer productivity effectively. That would be a tall order because you have to define things like effectively, but if one could pull it off I'd be rapt.

Update: I have since fixed the terrible bug! 
I'm posting this because when I rant about these things to you folks I tend to come up with a solution, and I've been at this since last night. Skip it if you'd rather not be used like that. It's not a programming question, though I will describe the problem. There's not really code as such.
[\r\n]* (zero or more carriage returns or line feeds) yields a proper set with two transitions
[^\r\n]* (zero or more of anything but carriage returns or line feeds) matches any characters (incorrect). The set has one range with all unicode code points in it, and when you invert the set and then minimize the result it will actually crash.
[^\n\r]* (functionally same as above) but works properly, yielding a set of all except carriage return or line feed. This despite the sets ostensibly being sorted.
I thought I narrowed it down to a normalization routine I have that takes overlapping ranges and merges them. That still might be part of the problem. However, I removed the call to the normalization routine and it still fails my test, so something else is at fault further downstream.
One of the issues is this is in live code - with deployed nuget packages and codeproject articles, and I only just discovered it. So there's some pressure on me to fix it, albeit self imposed.

It's actually based on some simple mathematical concepts.
I know enough about the present bug that it has to do with the way I'm sorting and categorizing ranges of characters.
I wouldn't even use ranges except I need to in order to make Unicode practical, but it does cause the algorithm to significantly deviate from what you'd find in a textbook.
It all works, but basically here's what's going on:
Range 1: 0-12
Range 2: 10-0x1ffff
It works fine if range two comes before range one, but how do i sort this? Normally it needs to sort such that Z-A becomes A-Z and therein lies the issue, or at least an issue. Maybe I can side step it somehow. Still stewing on this.
Edit: I just realized it's groups of ranges I'm trying to sort. Maybe I don't need to at all?

Does the issue only apply to control characters, or do you have issues with other match groups not in order?
e.g. if [^\r\n] fails and/or crashes, does [^rn] fail and/or crash also? If the latter fails also, then maybe you have an issue in your normalization routine. If only the former fails, then I'd have to suspect that it has something to do with handling "special" (i.e. control) characters. Does the group [^\v\n] also fail? What about code>[^\n\r\a\v\t] or other combinations of control chars? What about [^abc\n]?

I would say you should never do any of those. So do not attempt to solve anything.
All of those are unbounded and optional.
Something like the following is correct in that it provides a bound and is not entirely optional.
^\d[^\r\n]*[\r\n]+

Well, I caught this as part of a larger regular expression, I'm simply taking out a portion in order to simplify.
In my engine, it's perfectly fine to have a zero length match because every subexpression is an expression. It's expressions all the way down. 
(Oh, and I get the same results with +)

Might be an ordering issue: \r(0x0d) > \n(0x0a).

It is, but I just can't find where it's creating the problem. I've been kind of avoiding it at the moment.
