It's fascinating to me how some solutions in programming become 'trendy' and get used everywhere, even when it may not be the right solution.<p>And then other solutions, like the "COMB GUID" from 2002 have stayed in relative obscurity despite neatly solving a small, concrete problem so many of us encounter.<p>The author's 20 year old solution is amazingly similar to the recent UUIDv7 draft, right down to assigning 48 bits to the timestamp component; buried on page 6 of an otherwise unassuming article.<p>This should have been a revelation for everyone building database backed applications, but instead has either been outright ignored or reinvented in various ways over the years instead.<p>Makes me wonder what other solved-problems our profession has largely overlooked.
