Timeline:
5-9-2021: First 15-pointer
5-10-2021: Second 15-pointer (Improved it to 16 points on 5-18 and 17 points on 5-19)
5-16-2021: Got 200 weighted points sometime around the 16th.
5-17-2021: Five 15+ point problems :)
5-18-2021: Highest score (as of May 20th) on this problem, although my solution is kinda wack
5-20-2021: Got fastest code for this problem
5-22-2021: Ten 15+ point problems!
5-23-2021: 100 problems solved! Also I'm now in top 1000 by points.
5-24-2021: 1<<7 problems solved :]
5-25-2021: First 20-point problem! Also 300 points and top 800 by points :)
5-26-2021: Fastest submission to this problem.
5-27-2021: Top 700 by points, 200pp, and 55 problems solved today (37 with Rust)! Also fastest solution to this problem.
6-3-2021: This is what happens when a programmer is bored.
6-13-2021: Top 600 by points!
6-17-2021: Fastest solution to this problem. My solution runs in 0.11s, and doing bool f(int n) { return false; } runs in 0.10s, so my actual program runs in 0.01s (and I think the rest is function overhead and the tester program).
6-28-2021: Spent a lot of time today golfing Longest Flight Route. It's not very honorable to use the ruby trick, but if I don't, someone else will :( compression methods like that should be banned
8-6-2021: After a LONG time away from DMOJ, I came back and got my first 25 pt problem :)
8-24-2021: Somehow I got the fastest solution for this problem (on Yosupo Judge) on my first submission :o. After I improved it, the next fastest solution takes 69% more time than mine lol. (Edit: I have now been overtaken by nor!)
7-7-2022: I solved Hello, World!
6-8-2023: 
Fun Problems:
CCC '04 S3 - Spreadsheet
DWITE '07 R4 #5 - It all adds up (slightly harder than above)
