Worst case is when someone adds a comment to tell you that you publish the same article 5 years previously!

Reminding yourself ... first you have to remind yourself that you HAVE written about the problem before, then you have to find the note that you wrote.

Some disappointing results, and some fantastic ones. Most of the dahlias I grew from seed have produced a respectable set of tubers, and the old non-productive potted plants my wife binned have recovered dramatically on splitting and planting out. Sadly a couple of my prize plants got some rot.

But if you don't have the courage to make the hypothesis and build the investigation you'll never learn anything new, and you'll never learn how to review "proofs".

But will the AI ask you to clarify the question when you give it some natural language that is (humanly) ambiguous, or will it take the text as given?

(Thinking messy combination of ANDs and ORs - will the AI simply use logical precedence, or will it ask for clarification on bracketing?)

Unfortunately it's not documented and the suggestive "reset_value" column was blank for all the options I tried - but at least the names are there.

It's not the vax it's the cat.

You may think it spends all its time scratching you but those are hypodermic claws injecting nanites that can draw power from the electrical signals to and from your brain. What else could make you put up with the way it treats you.

Quoting 2016
"It's an interesting observation that the Windows implementation is inherently slower but scales better because of the randomness while the Linux version is inherently faster but suffers significant index contention at higher concurrency. This type of reversal isn't uncommon ..."

1/2:
A comment I made in a discussion on the Oracle Forum about sys_guid() several years ago forums.oracle.com/ords/apexds/... - the Windows and Unix implementations are (were?) completely different, leaving the Unix one highly sequential and the Windows one extremely random:
