Another year where I fill out a bracket for the college football bowl games with my in laws where I only vaguely know what I'm doing. They are football fanatics.

I easily met my New Year’s resolution this year. I once again acquire a bike and took it on a few rides. I’m so glad to have gotten into biking again.

A little late to say this, but I had a couple of coworkers give their condolences/ask how I was doing after the Brown shooting. I was fine, but simple gestures like this matter.

It made several mistakes along the way. Forcing it to prove it this way makes it make a lot more sense to me

Reading about RF waves also led me down the path of reading about sound waves. I learned this fun fact:
Perfect fifths sound nice to our ears because 2^(7/12), the ratio in frequencies between the two notes, is 1.498… very close to 1.5.

Systematically studying how to train or use an LLM to effectively say “I don’t know” seems like an interesting area of research: arxiv.org/pdf/2407.18418

Among the news about the tragedy at Brown, I learned of this relatively new art piece there: www.brown.edu/news/2019-05...
It would’ve only been there for a few months while I was a student, but I’ll have to check it out when I’m on campus next.

Big yikes, but TIL that sympy can generate code in other languages!
Yikes, I just found a nasty bug in SymPy. Spot the difference between these representations of the equation! github.com/sympy/sympy/...

Re: Rob Reiner’s death: All In The Family is by far one of my favorite sitcoms. It was far, far ahead of its time. So well known for broaching social or cultural or political issues that were considered taboo at the time.

This book is apparently AI slop irl.

Okay, I went down the single sideband (SSB) modulation rabbit hole and how the math works out (in part because I'm studying the exam content for an amateur radio license).
I got distracted this evening reading all about signal modulation and man is it fascinating. I had no idea how information is encoded at the physical layer in electromagnetic waves, but now I feel like I have some idea.
