One day, your database will start rejecting writes even though nothing changed.
No deploy, no traffic spike.
If you’re using INT AUTO_INCREMENT, there’s a hard limit at 2,147,483,647. When that limit is reached, MySQL doesn’t overflow or wrap around - it stops incrementing. Every new insert gets the same ID, and you start seeing confusing “duplicate primary key” errors everywhere.
The fix isn’t restarting the database.
You either increase the ID range by moving to BIGINT, or you swap in a new table with a larger ID type and continue writing while backfilling old data. The real prevention is monitoring auto-increment usage early, before you’re forced to fix this during an outage.
Simple systems have limits. This is one most engineers discover the hard way.
I've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become available over the last ~year and a failure to claim the boost feels decidedly like skill issue. There's a new programmable layer of abstraction to master (in addition to the usual layers below) involving agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations, and a need to build an all-encompassing mental model for strengths and pitfalls of fundamentally stochastic, fallible, unintelligible and changing entities suddenly intermingled with what used to be good old fashioned engineering. Clearly some powerful alien tool was handed around except it comes with no manual and everyone has to figure out how to hold it and operate it, while the resulting magnitude 9 earthquake is rocking the profession. Roll up your sleeves to not fall behind.
Finally Done with the notes of API Design.
Topics covered:
>Core API Design
>HTTP Methods
>Authentication and Authorization
>Real world Scenario Questions
Now which topic should I cover?

Breadcrumb separators belong in CSS, not HTML. Just use the `::after` pseudo-element.
nav > ol > li:not(:last-child)::after {
content: " / ";
color: lightgray;
padding: 0 0.5em;
}
The `:not(:last-child)` ensures no trailing separator after the final item.

PayPal will burn actually, they are one of the only global payment platforms that totally excluded Africans and Nigerians especially. And they literally gave the most stupid excuse for doing it.
Now they want to stroll into the African market like nothing happened.
i just don’t understand the pay difference between software engineering in the UK and USA.
same SWE role $200,000 in the USA and £70,000 in the UK
Why and How is this even allowed?!!!!!!! or is there something i’m missing?
