This will be my last post here on X/Twitter. I've decided, as many others have, to migrate to Threads.

I attribute part of this decision to business logic - Twitter is dying. Why waste energy on a platform that will die? But on a more visceral level I just can't stand Musk.

On a separate note, I've become a registered financial advisor in Canada, and started blogging regularly on https://t.co/fr3krlO7yd I have very high regard for many of the people here, so I hope we can connect elsewhere.

Say what you will about other billionaires, but I don't they match his level of narcissism. So, I'm taking my business elsewhere.

@rlmcelreath @MatthewBJane I was surprised how high the correlation was. Out of curiosity, what's the maximal information coefficient for that data?

@MPelletierCIO The average home price in Canada is more than $700k. Average household income is only around $75k. But house price to income ratio is only 150%?

@amendandpretend @modestproposal1 This. The number of people in a project doesn't matter so much as quality. A team of 160 very good programmers can easily outperform a mediocre team of 16,000.

@FakedNom @AndurandPierre I get your point, but the fundamental picture today is similar to that of the 2000s as well for oil.

Testing. Testing. (I'd changed my username a few weeks ago)

@bdkoepke They just simulated it, unfortunately. It wasn't real.

@GestaltU Keeping in-sample and out-of-sample data separate is one of the basics of statistical analysis. I'm surprised that's violated so often.

@Grady_Booch I stopped seeing ads after I blocked every ad I found

[Jin Choi @jinchoice]

@bdkoepke 🤣 what's your mastodon handle?

[Jin Choi @jinchoice]

There were ~1,000 users when I joined my #MastodonSocial server (https://t.co/mxubWZ5YHk) about a week and a half ago. There are now nearly 20,000 users. The poor server admin is going nuts trying to scale resources.

Unless you operated large systems, it’s hard to appreciate both how they work, and how they break.

Twitter won’t go down with a big b, and it won’t go down irreparable.

Things will work fine for a while - thanks to no new deploys! Then, here’s what’s likely to happen (cont’d):

[Jin Choi @jinchoice]

I want Twitter to go down so I don't have to suffer terrible takes like this

[Austen Allred @Austen]

Twitter now has early seed stage level company chaos but with thousands of employees and billions in revenue and entirely in the public eye.

Absolutely wild to watch.

Great interview of the founder of Mastadon. He actually sounds like he's doing it for the cause and not for the money.

@lopezlinette SBF sounds like someone who's allergic to deep thought that can't be expressed in a mere handful of paragraphs. He's not the only one, though. It's the disease of our age.

[Jin Choi @jinchoice]

@JessicaNutt96 They mostly use simple regressions?
