Two YouTube math channels. I have a degree from 2012 before switching to software; now I’m on a path to becoming a schoolteacher as a 2nd career. Using YouTube as a way to deliberately practice teaching & refreshing skill. “Math Can Be

Not sure when this was written, but I believe I found it ~3 weeks ago (pre-FLT and NS announcements)

Not mine - stumbled across this short story about a week ago. Not sure when it was written, but it was before Anthropic’s FLT announcement.

As a math educator, I strongly dislike both Strang and Axler for a 1st course. I've heard great things about Strang's lectures, but his book is disorganized and too heavy on computation. Axler's book is wonderful, but as expl

Neat! It feels like bridging the gap between infinitesimals intuition and epsilon-delta formalism. I wonder whether this approach could make a 1st course more rigorous, and whether that would be a good thing.

https://mujo.app I’ve been building a minimalist productivity app for musicians. Mujo adds time tracking, task management, notes and other “practice journal” tools into a simple metronome interface. Been hacking at the iOS versi

I built a proof of concept for a VC-scale app, and something like this is one of the core features. I applied to YC S24 and didn't get an interview (SUPER understandably). If anyone wants to hear details, shoot me an email (in bio); th

I’m sad to see this - I used to binge their videos a few years back. As someone who discovered and fell in love with classical music late in life (~26), and is now a hobbyist content creator [1] they were a terrific bridge into learning abo

Just hit top 30 in all the standard races - thanks so much, this was such a delightful way to practice my new Glove80 :)

Building Mujo, a minimalist musicians' practice journal for iOS. It integrates time tracking, note taking, and task management into a familiar metronome UI/UX. I dearly love it (1400+ hours logged!) and it's slowly building t

I think so. Another recent entry is purelymail, which I love because it's a flat rate for unlimited domains. I'm trying to spin up multiple "small bets", and per-user pricing is unreasonable, and for better or worse, I d

Well, cross off another from my ever-growing list of “someday” projects. Looks excellent, well done!

Yea I’ve run through that a couple of years ago - was brilliant, had a lot of fun. But I mean to stay up to date and somehow contribute from the sidelines

I wish I had the free time to keep up with the mathlib project - this is so cool. Is there any way someone can get involved in a super hands-off way?

Today's a great day - what a delightful 2000's throwback on all fronts. I wonder if there's any connection between this article and the rumored Pitchfork -> GQ reorg.

Congrats! It’s a joy to see this today - I studied briefly with Prof. Wright, and have had a copy of Indra’s Pearls in my bookshelf for ages. It’s really beautiful art and math (from the little I understand).

I loved my 12 Mini, but by not including it in the Pro line (better materials, camera, screen, etc) I feel they never gave it a full chance - signaling from the outset "smaller is less". I desperately want to go back to the smalle

Extremely passionate about classical guitar. I played electric in high school and developed some chops in jazz band. Loved it, but like many others, dropped it completely in college. Years later, I moved to SF for a FAANG and had an impossi

As a hyper-niche classical guitar streamer, I’m stoked for this. I previously ended my Affiliate program just to feel comfortable multi-streaming to YouTube: my target audience is so niche it feels important to reach audiences where they’re

Omg I haven’t played games in years, but this is the first remake I’m fully stoked for. I remember playing this when I was like… 8? Great game, and the VR treatment looks really well done. Congrats!
