Thanks for the interest! Here are my other aromatic posts, and beyond benzene, I have posts on these PAHs: * 1,3,5-tris(biphenyl)benzenei -- https://www.instagram.com/p/CxZgDpWLk2b/ * hexa-cata-hexabenzocoronenei

Hope it’s ok to share my chemistry Instagram with a plastic model of Hexabenzocoronene (HBC) that was mentioned in the article.[1] I posted similar photos of other polycyclic aromatic hydrocarbons (PAH) including napthalene, which are also

The article repeatedly cites “2 billion users” of Airbnb. That isn’t true, right? From casual Googling, I’ve seen is 5 million hosts and 1.5b stays—which is nowhere near 2b users (alltime, MAU, or otherwise).

This is the short-sightedness of market fundamentalism. To take this to a ridiculous extreme, if I decide that taking care of my children is no longer ROI-positive, should I just decide this market has shrunk and the prudent thing to do is

I generally prefer using vim (and have started using neovim recently). Does anyone know when/if Cursor will provide official support to plug-ins that allow me to us its functionality in neovim? I've tried VS Code a number of times

The similarities and differences with the 1997 MS-Apple deal are interesting. Arguably, the $150m that Microsoft invested was less significant than: (1) the vote of confidence to customers, 3rd-party developers, and investors that Apple wou

I partially agree. I don’t love typing on iOS/iPad OS and am much happier on a Mac. That said, hundreds of millions of people in the younger generation type blindingly quickly on software keyboard. Perhaps, like the dying art of handwr

I was classmates with several people who did well in Math 55, and knew some people who were teaching fellows for it. Very smart folks but they themselves would not have compared themselves to Simons as mathematicians, esp. at age 18.

I love the terminal and use vim as my primary text editor but I can't remember the last time Mac OS full-screened an app for me unless I told it to. I drive most of my mac through keyboard shortcuts and minimal pointer interaction. Per

From the article, "A few months ago, I started a magazine assignment to answer some questions about SARS-CoV-2 and the immune system. I encountered paragraphs like this"... and the author links to this this [1] New Yorker article

(I think) technically, all of these mathematical objects are tensors of different ranks: 0. Scalar numbers are tensors of rank 0. 1. Vectors (eg velocity, acceleration in intro high school physics) are tensors of rank 1. 2. Matrices that yo

This anecdotal info from my part but I regularly visit some close friends from school who now live in a semi-rural area. My friends’ kids raise livestock like sheep for 4H and I joined them at their local 4H annual dinner where I met most o

+1 strong agree. I like Google Docs’ realtime collaborative editing, but the wysiwyg formatting (even if one has memorized the keyboard shortcuts) makes it hard to be fast the way I am in a Markdown-aware editor or vim. Plus I miss my vim m

I have read many Lewis' books and admired his skills as a storyteller and stylist for decades. I found Going Infinite fun to read but less satisfying than The Big Short, Liar's Poker, Moneybag, etc. As a good complement or even su

Thanks for highlighting Bishop to me! I've self-taught through various resources esp. Goodfellow et al 2016. It's taken me a number of years to rebuild my math knowledge so that I feel comfortable with Goodfellow's treatment

Assuming you have an external monitor already, one can get pretty nice deals on Mac minis. I paid less than $1500 for an Apple Silicon Mac mini and a similarly specc'd MBP cost something like $800-$1000 more. Later on, I can continue t

Wow a reference to Rainbow’s End! IIRC that novel was set around 2026. I don’t think we’ll have Vinge-style AR/VR contact lenses for many years to come. Certainly not by RE’s fictional timetable… :(

Thank you! This has been bugging me and the references I found online to Newton Howard all seem to refer to the blue robot as "Optimus Prime". I know Howard is not necessarily a fan of the toys/shows/movies. But c'm

“Reverse imposter syndrome” is a great coinage; I’m going to start using this!

I'm honestly a bit surprised that someone who's seen it would comment publicly. I know this is a short and generic tweet and Palmer is established enough to say whatever he wants but still. This feels different than the anonymous

Agreed. Zuck was frustrated that FB did not own and control their own computing platform and were subject to limitations that Android +iOS imposed on his company. As someone who knows the history of the Wintel duopoly and a participant in t

I wasn’t around for the earliest iterations of PowerPoint but according to Wikipedia [0] for its first several years, PP was Mac-only (mid-1987 to mid-1990)…even though MS had acquired the PP developer as it’s first big Silicon Valley acqu

After you’ve had a chance to learn single-variable calculus and introductory linear algebra, I highly recommend two books for “second courses” in these areas: 1. “Vector Calculus” by Baxandall and Liebeck is excellent. Begins with a semi-fo

Quite good and fair article about the changing scientific consensus and the various reasons that the ‘French paradox’ got so popularized ~30 years ago. The Maintenance Phase podcast did a good episode on this updated thinking (September 27

Been using Overcast pretty much since it launched and I've also be listening to Marco's Accidental Tech Podcast for even longer. A bunch of changes over the years but still love the smart speed and other features. Glad to see indi

Yes this bothered me too. I vaguely knew MIT was founded in the 1860s so I guessed the rough date of the talk. What clarified it for me was this quote “I then looked at all the titles and abstracts from the current issue of Science” where t

Interesting! The author of the New Yorker article is a CS professor who has been studying work, productivity, tools etc for awhile. I’d recommend the hyperactive hive mind concept from his previous book “A world without email”. Refers to bo
