I've used Beeper for about a year with Facebook, Signal, Instagram, Twitter, LinkedIn, and iMessage. Instagram signs me out once a month or so for security suspicions, but I just reconfirm my account with 2FA. Other than that, no issues.

The course is free and funded by Open Philanthropy.

It's not taught by James solely, but there's weekly discussion groups on readings chosen by a mix of alums from OpenAI and Oxford's Future Of Humanity Institute.

We got similar news at Cornell today, with professors being advised to go online asap but will be forced to in early April which is also when students will be sent home. The problem here is that most upperclassmen live off-campus and can't be forced to disperse. Furthermore, many students are from NYC where they'll visit during spring break and then come back to Ithaca. The atmosphere on campus is very nonchalant; most are more upset by cancelled events than the possibility of encountering the virus.

For reference, the generally accepted standard for determining age from blood is the Horvath clock [1]. It seems to be accurate and only uses a penalized regression. Keep in mind this represents what your age is in reference to a "healthy" person. For example, a 50-year-old who smokes may have the equivalent practical age of a 60-year-old who doesn't. The Horvath clock is useful for evaluating lifestyle changes and your overall healthspan.

If people want to learn more about how DNA methylation relates to aging, I recommend reading Lifespan by David Sinclair.

And 60+ years later their guess is semi-confirmed by this study; if humans want to be in space for a long time they'll need artificial gravity to avoid most of the harms mentioned in the article. Amazing that 90% of his genes returned to normal expression. I wonder how long humans can withstand microgravity before that number drops severely, or if it's a gradual decline...

Does this violate any of the Google or Apple's Play Store TOS? People are calling for the government to step in but a quicker move would be to remove them from the app store; at least if there's a violation.

I was in one of Hopcroft's courses (an author of this book) for a while and if this book is on brand with his style and fields of study, it's super theory heavy. You won't write a line of code; you would not be useful to a company hoping to apply data science in the world.

Having been introduced to this idea by CGPgrey on the Hello Internet podcast, I didn't know there was such a concise version of this idea written so well. I've tried to spread this message to my friends irl, and Aaron puts it better than I ever could.

Amazon Go 10 years ago

NPR's Planet Money podcast did a story two months ago with the inventor of the self checkout machine, Howard Schneider.

At the end of the end of the episode he was asked what his "dream" supermarket would be, and he said one where people don't have to check items out. They walk in, grab something, walk out, and are automatically charged.

This seems to be exactly what Amazon has done. Pretty amazing to see the realization of his dream be announced only two months after his interview.
