The only reasonable design is to have two kinds of API keys that cannot be used interchangeably: public API keys, that cannot be configured to use private APIs, and private API keys, that cannot be configured to use public APIs. There's no one who must use a single API key for both purposes, and almost all cases in which someone does configure an API key like that will be a mistake. It would be even better if the API keys started with a different prefix or had some other easy way to distinguish between the two types so that I can stop getting warnings about my Firebase keys being "public".

> Is there something less cooperative than a task that doesn't yield its control back to the main thread? Of course it does yield back to the main thread in my example, at each await point, just like any other cooperative task.

In my case, I specifically want an independent execution of a task. Admittedly, it has to catch its own exceptions and deal with them, as you pointed out, because that's part of being independent.

(Technically, in issue A it doesn't crash the running thread. The event loop catches the exception, but it complains later when the task is garbage collected. Issue B is fine for my use - when the event loop shuts down, it cancels remaining tasks, which is exactly right for my server.)

Then someone should really update the official python docs that explain the fire-and-forget pattern (https://docs.python.org/3/library/asyncio-task.html#asyncio....)! I had a FastAPI server, and calling a particular endpoint is supposed to kick off some work in the background. The background work does very little CPU work, but does often need to await more work for several minutes, so it's a good fit for asyncio. How do you want it to be structured? (In other words, on the level of human requirements, it IS fire and forget.)

The thing that burned me with asyncio primitives is that calling an async function doesn't even schedule it (by default). The pattern for fire-and-forget is impossible to guess when coming from any other language - although it's called out in the docs. You must also call create_task AND you must maintain a collection of tasks because otherwise the task might not run, because it can be garbage collected before running, AND you must clean up completed tasks from your collection.

But if you release the O2 and convert it into diamond, then by my highy-suspect back of the envelope calculations, it'd be a diamond that would fit into one square kilometer, 87 meters high. It would make quite the tourist attraction.

Googling Stackoverflow itself can sometimes be a high expertise skill, simply because sometimes you need a fairly good understanding of your issue to figure out what to search for. A recent example: we had an nginx proxy set up to cache API POST requests (don't worry - they were idempotent, but too big for a query string), and nginx sometimes returned the wrong response. I'm pretty sure I found most of the explanation on Stackoverflow, but I didn't find a question that directly addressed the issue, so Googling was a challenge. You can keep your job finding answers on Stackoverflow of you are good at it.
