Loved doing this w/ @codenprose.bsky.social!🥳
Notes:
0. Omg, I ramble A LOT. I apologize! Pls listen to this on 2x.😅
1. Paraphrasing @jay.bsky.team: "Today's [Substack] could be tmr's adversary." Curation's the next big thing. Whoever who builds SS on top of @atproto.com will become a millionaire!

I was lazy yesterday morning and slept until ~8. I'd literally woken up around 3-4a like usual, was lazy, and decided to go back to sleep.
I then woke up with an absolute monstrous headache around 8a.😖😖😖
I spent my entire Friday in pain and suffering.
Today I woke early again. Still had splitting

A lot of folks know me for one or two posts, and might not know I've created nine (9!) visual explanations of computer science topics, aimed at practitioners.
If you're looking for things to read this Thanksgiving, I think you'll love them.
Computer science is a lot of fun, when explained well. ❤️

Booooo!! I positively love winter! The air gets cold and crisp; stepping outside makes you really feel alive!! I also love how it gets dark super early so you're incentivized to stay inside and get work done. Winter is definitely my favorite season of the year!!

"A book is only a book when someone else reads it."
This is one of my favorite quotes ever. I love creating and for many years, created solely for my own enjoyment. And that was wonderful.
But I feel myself now moving into a new season.
"We live in a society," as the famous meme goes. It is time.

A big reason I'm at the gym lifting now is bc of S. I've never been a vain person, concerned ab appearances. To me, there were always better things to do w/ my time. But I started lifting recently bc S told me I was starting to look like a blob. And she was right! I was indeed blob-ifying.😭 S has

@bsky.app - not sure if anyone can help with this but I just got a new phone and something bizarre is happening: the timestamps on my skoots are for some reason 12 hours in the future? 🤔
For example, I posted this at 6:10 a.m. this morning but the skoot says 6:10 p.m. How do I fix this? Thank you!!

A marvelous Sunday. 🙂 Got lunch at Roebling Books & Coffee in the Mansion Hill neighborhood of Newport, KY and walked around ~2 hours after reading outside for a bit. S's traveling again so I've been on my own once more. When I was a young lad in my 20s living in NJ, I'd wander like this. Nostalgic.

My sleep schedule. I go to bed by ~9p and read for a bit. Then I wake every morning 3-4a to start my day! I've been walking ~25k steps daily for a month and it's been life-changing. My sleep+appetite have improved a ton! I recommend it!! Yesterday, I increased my daily target to 27,500 steps. 🙂🚶♂️

Visited new #cafe today! White Oak Coffee House in Cheviot, Ohio! On the outskirts of Cincy w/ ~8k ppl. I've been meaning to get out here for a while now but they're closed Sundays so it was tough.

As reported in the @wsj.com back in November 2009, this quote from Lloyd Blankfein, then CEO of Goldman Sachs, continues to occupy permanent space in my brain to this day:
Blankfein: being an investment banker is "doing God's work".

Watched The Running Man last night; liked it! I have two take-aways from the movie: 1. The act of choosing to have+raise children is increasingly the sole province of the privileged. 2. Having children's beneficial for the individual, sure, but it's really for society. That's the functional purpose.

As someone who only watches very occasional television, I found @dkthomp.bsky.social's latest Plain English ep incredibly alienating.🤔
I usually only watch TV when I eat which means I usually watch in 10min increments. Takes me ~3-5 days to watch an ep of anything.

One challenge with words is that they mean different things to different ppl. Words only have a single dictionary definition but ppl understandably think about different meanings for the same word. eg. For the word, "honor", I specifically think of seppuku. ie. there are fates far worse than death.
