What Hacker News says?
> The code isn't that complicated, you could probably implement training and inference for a single model architecture, from scratch, on a single kind of GPU, with reasonable performance, as an individual with a background in programming and who still remembers their calculus and linear algebra, with a year or so of self study. Great overview. One gap I've been working on (daily) since October is the math working to…

HN discussionYou might want to take a look at Math Academy. I'm similar to you and have been using it since last year. My tool to get me through slogs is streaks, so I commited to doing a lesson (or at least part of a lesson) every day and I'm at 198 days so far. I wrote this at 100 days in case it's helpful: http://gmays.com/math I'm not sure if I'll have time to write an update for 200 days, but maybe at the 1 year mark.

HN discussion+1 for Math Academy. I’ve been using it daily for over a year now (started October 2023). I summarized my experiences after 100 days here in case it helps anyone: https://gmays.com/math

HN discussionIt’s been great for me. As of today I crossed 324 days of using it straight. I wrote about my experience here: https://gmays.com/math And yes, I’m a total fanboy. I’ve also known the founder for over a decade and he’s been working on it for most of that time. Math Academy came out of him helping his son learn math even before that. I haven’t found anything close to teaching math than this. It’s legit.

HN discussionYes, Math Academy is insanely good. It's a lot more intense, focused learning and less edutainment. I'm an adult and not a kid, but wrote about my experience after 100 days of using it daily here: https://gmays.com/math The Math Academy team (including the founders) are also active on X/Twitter: https://x.com/_MathAcademy_ And there's a Math Academy community on X here in case you want opinions from other users: htt…

HN discussionThese days a Nasdaq ETF is likely the best bet (it's what I use in my IRA) since it has been conistently outperforming the S&P 500. I'd be cautious with the more exotic leveraged ETF. Instead, for my non-investment accounts I've been mostly holding the Mag 7 since last year (after rotating out of pandemic stocks following the rebound). I shared my results over the last couple of years on by blog where I document my…

HN discussionI'm surprised no one mentioned Mathacademy [1] yet. It's not free, but offers great value for money ($49/month). Last week someone even posted a great review of it [2]. [1] https://mathacademy.com/ [2] https://gmays.com/how-im-relearning-math-as-an-adult/

HN discussionI didn't want to hassle with migrating my WordPress blog, so now just deploy it to Github > Cloudflare Pages so it's served statically (fast + secure). It's free too, wrote a blog post on it a couple years back: https://gmays.com/how-to-host-wordpress-sites-free/ But these days any new site I build is on NextJS since coding agents make it a breeze.
