Did you use a dirty sock as a filter? I heard that's the best form of Japanese pour over.

His interview with Stephen Colbert (only found on YT because broadcast equal time laws) was really good. I very much appreciated his POV, also found it refreshing.

The mathematician and podcaster Demian Goos has been obsessed with the story of set theoryโ€™s birth for years. Last March, he found a letter from 1873 that was thought to have been destroyed during the Second World War. It rewrites the story he thought he knew.

Certainly a lot of handwaving, but it's easy to imagine the coding model improvement trend line colliding with the run it on an ASIC trend line and really changing what software is.

A color-coded binary tree displaying how to expand (x+y)^3. There are 8=2^3 terms on the bottom, and by putting them in "alphabetical order" and grouping like terms, you see that (x+y)^3 = x^3 + 3x^2y + 3xy^2 + y^3.

My coauthor Dave Perkinson made this diagram to explain the binomial theorem and I think it's the perfect distillation. Here's our draft book, Discrete Structures, if you want more: kyleormsby.github.io/files/113spr... ๐Ÿงฎ

Anybody use Google Chat for work, through Workspace? Tt's about the same as Slack for our needs and bundled in. Would love to hear pros and cons from anyone who's actually used it in anger. ๐Ÿ™

I think LiteFS would give you the folder, and the files would be stored in a SQLite database that is then sync'd to S3 via Litestream. I think? Maybe? The files themselves wouldn't be in S3, but you'd get the backup.

I like the page transition, it's easy on the eyes.

Buy Angled Spatula 32ย cm|12.6ย in. - online at Rร–SLE GmbH & Co. KG The angled blade allows easy lifting out of pans, moulds or baking trays. The straight edge is useful for cutting.

I splurged on a Rosle can opener years ago and absolutely love it. Spendy, but feels like I can pass it down to my grandkids someday. I'd personally splurge again and get a www.roesle.com/en/angled-sp...

Striking paper from researchers at Anthropic using a randomised control trial to look at the effects of AI use on skills acquisition.

TL:DR โ€˜We found that using AI assistance led to a statistically significant decrease in mastery.โ€™

How's the Windows support for hk/pkl these days? Last time I tried I think that was the main rub.
