aaaaanyway, i have come up with a wonderful trick which would work marvellously on zen 5 without a great deal of effort. but less marvellously on zen 4 and i have no fucking clue how well intel's doing with avx512 anymore.

these things are insidious because the way you're told to deal with ISA support is to ask is it supported with cpuid or something. and so you ask and it helpfully says "yes, i support that". it doesn't say anything about whether it's dogshit slow.

and how do you work that out? glad you asked:

1. know the bug exists at all, somehow
2. implement a fallback
3. sniff the processor model and switch between the two implementations.
4. have a few of these stack up, give up and choose which architectures to penalise.

thanks AMD, another fucking performance bug to work around

Also I recognize I'm in an extreme minority among authors, almost all of whom have day jobs and/or side gigs and/or partners or families whose financial situations offer them support. This is the same for most creative professions. The arts of any sort are a tough gig.

2010 was the year I could live entirely off income from books, that income being advances and royalties. That was 10 years after my first book came out and 5 years after my first novel. Prior to that freelancing and corporate writing paid my bills (and my wife's income was our safety margin). It helps I'm a bestselling author and I release a novel a year, so the income is relatively steady.

So Ford holds the record for shortest interval between assassination attempts. But Trump and Reagan almost certainly hold the record for presidential assassination attempts in closest geographic proximity to one another.

I'm seeing some weird behavior with FastAPI and async.

I have a function:
```
async def foo(r=[]):
if r: return r[0]
r.append(someobj())
return r[0]
```

Now I have that declared on a route via the usual:
```
@router.get('/somepage')
async def get_somepage(foo : Annotated[someobj, Depends(foo)]):
xxx
```

But in the foo function, I print the id of the r list, and each time somepage is fetched, the list is different.

I did finally just move r into the module name space, and that fixed things. But it's pretty clear that FastAPI is doing something wonky with function calls.

"A Tribute to Attribution" - Chainsawsuit by Kris Straub, November 23, 2011. (15 years later, even in the Fediverse, some folks out there are still like this.)

• gifv: Six-panel comic strip. Panel 1: a smiling person looks at a comic on their computer, saying, "ha ha! this comic strip made me laugh, gotta share it." Panel 2: the person makes a mischievous face and says, "but first things first!" Panel 3: close-up on the computer desktop showing the comic. The title and artist's name is selected in an image editor, and the mouse cursor is about to click the "delete selection" function. Panel 4: the comic's web URL and copyright notice are now selected in the image editor, and the mouse is again about to click "delete selection." Panel 5: The artist's signature is now selected and the mouse is about to click "delete selection." Panel 6 shows only the text: "welcome to tumblr.," The credit line at the top of this comic reads "ChainSawSuit.com"

How do we decide what's important?

Let's ask ourselves: who, what, why, where, and how?

- who: there are some people we don't have to pay attention to, and there are some people who are always saying the same thing. but if there's a source that's reliable, maybe that's somebody we should pay attention to?
- what: does this source sound plausible? the last decade has really stretched this, but there are still limits: teleportation, even to waffle house, remains unlikely

There are many things you don't have to care about:

- somebody who doesn't work on your project thinks that you're doing it wrong
- "you're a bunch of SJWs! code should not be political" [see previous advice re: bedspread]
- "you removed my emotional support bug"

Lots of stuff you just don't have to care about; even if they are mentioning your project specifically by name. You have a limited amount of time in the day, and on this earth.
