Linear algebra and webdev

Added 2022-03-23

Wrote up some Axler linear algebra exercises, made a basic lesswrong clone to practice CSS.


Got up at 7:30, drove myself to the chiropractor at 8 and got home by 9. Morning routine 9-10 (exercise, swim).

Setup a math writing beeminder goal. I really want to start finishing my projects.

10-12 Writing up axler solutions, did a lot of section 3d and improved my understanding! A short summary of what I learned (for my own future reference)

Most of the time was spent on 3d/4, the other exercises I did pretty easily (around 10m each)

12:00-12:30 Messing around

12:30-1:10 Drive brothers to the ymca

1:10-1:50 Chatting on discord, taught someone about the rationals being countable and learned that squids have shells in their heads (wtf?)

1:50-2:40 Lesswrong clone, implemented a html template tag which does basic escaping like lit-html

2:40-3:30 Get brothers and drive them home

3:30 - 4:10 Worked on a (bad) javascript hover link preview for my axler solutions project. Haven't published it as it was too buggy Here's what it looks like though link-hover-preview

4:10-5:00 Reading random css stuff, learned about CSS filter and some color stuff. Learned the yak shaving term. I'm realizing now you can do a good amount of image editing in pure css, which is interesting.

5:00-6:00 Trying to debug wierd popup css bug, an absolute positioned element messing with page flow. Diden't figure it out but did improve my understanding of css somewhat.

6:00-7:00 Eat dinner and chat on discord

7:00-7:20 Found a great physics youtuber, got a vague idea of how lagrangian and hamiltonian mechanics work. Tomorrow I'll spend some time studying physics

7:20-7:40 Setup md-img-paste for vim and fixed my journal setup

7:40-8:40 Journal


Overall an okay day. Today will be the last day I do this timestamp based journaling since it takes up too much time and it isn't very readable.

Things I'll do better


Edit (11pm): I spent an hour reading lesswrong, found a bunch of really good stuff I'll continue reading tomorrow.

Primarily 1 and 2 will be critical for me. especially the advice to "pair up" with another person learning the material (ala study group)

Also really important advice: I need to start using anki more for ladr so I remember the material.

It's motivating to see someone able to read and review a textbook a month. I think I can do the same if I spend ~3-5h/day on it.
