At this point I feel like I should do a stream tomorrow to talk about the replies I've seen to this post. I completely disagree with people's umbrage about use of FPS as a metric here: A) that is exactly what time-to-show actually is (we measure 1% and .1% lows in for a reason!), and b) to me, FPS is the most relatable number for response time for average people to understand given that they don't work on software performance for a living like I do.
Many people (especially gamers!) intuitively know what 10 or 11fps responsiveness feels like for an action. Few intuitively know what "94ms" responsiveness feels like.
I also find it unacceptable to call this "load time" because the user is not asking to "load" anything - it is an action they are taking from a UI that they perceive to be contiguous, and the choice to involve a "load" of any kind at this point is purely the fault of the designers of the system, not some inevitability. Everything has already "loaded" from the point of the view of the user, and if you are claiming to have done a rewrite with performance "top-of-mind", you should have preloaded or precached whatever it is that you believe takes 94ms to "load" here.

Just want to make sure I'm reading this right: Microsoft rewrote the run dialog with performance "top-of-mind", and the best they could manage to do when putting up a single text box was 10fps?

Just got to meet @cmuratori, easily the most humble and talented member of @thestanduppod that I've met, consequently he is also the most arrogant and mediocre... Sorry Casey, I haven't met anyone else and context matters 🤷

@GulagInmate5790 @BrentWeeks @teachrobotslove Yet even fools grow old, something is not wise because it has persisted. Wisdom is earned through prayer and discernment not tradition or repetition. I can do something wrong a million times or watch and learn and get it right in just a few.

@BrentWeeks @teachrobotslove And there's generations of wisdom baked into long-surviving tradition.

I'm not temperamentally a conservative because I'm extremely high openness (99th percentile) and a writer on top of that so I should have been brainwashed into socialism I guess, but at some point you see that most exciting and novel possibilities are dead ends, creative ways to bury your children, genetic destruction, a set of laughing skulls. Almost every flashbang colorful parade of hedonism leads straight to the cemetery.
It's much easier to be wrong than it is to be right.

@ThePrimeagen what is the freebsd song we were jamming to last stream?

FULL KEYNOTE -- me + Guy K at SXSW on why privacy is a fundamental guarantor of a gorgeous, good life (not an absence, not a vacuum, not abstract). And how AI threatens privacy. And why Signal is so special and why you should use & love & support it ❤️

Xanax, Ozempic, etc. trying to fix any of your problems with pills rather than confronting the source of your issues will just increase your mental and physical instability.
The only real solution is to address the source. Work on your health (Physical), face your fears(Mental), read your Bible (Spiritual). Like our Creator, we exist in three parts. Most people don't take care of any of them and wonder why they don't feel great.
"For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmie powers over this present darkness, against the spiritual forces of evil in the heavenly places."
Ephesians 6:12 ESV

Let's do some math on how big a spacecraft would be needed to divert 2024 YR4 in 2028 so it would miss in 2032 - according to @astroEdLu the velocity uncertainty is 0.35m/s with a 2.3% chance of impact. That means there's roughly a 0.008m/s range in velocities which lead to an impact in 2032, change it by more than this much and it misses. That's less than a cm/second.
But on a 2028 intercept we'd have half the time, so, double that to 0.016m/s, let's say 0.02m/s just to add some margin.
When 2024YR4 flies past Earth at the closest point it's moving at 13km/sec, let's use that as our impactor velocity.
Slow it down and it arrives early in 2032 so that it passes through the encounter before the Earth arrives there.
Dividing 0.02 by 13,000 gets 1.54E-6 the required mass ratio between impactor and asteroid, that's assuming no beta value enhancement.
Estimates of the asteroid mass range from 25,000t up to over a million. So our spacecraft needs to be anything from 40kg to 1,600kg on impact. These are trivially possible to send out to 0.05 for a 2028 intercept, the hardest part is the high precision terminal guidance, hitting it straight on would be on the dark side of the asteroid. If we come from a different angle then cosine losses increase mass requirement.
But then we need to make sure we don't break the asteroid by hitting it too hard, which makes my recent video at the Ames Vertical Gun Range relevant!
