Backpack Search

A while ago, one of the water bottle sleeves in my backpack started to tear. In addition, the nature of my traveling life began to change. I was taking weekend trips to San Francisco, and the occasional long-term trip back to Minnesota (such as I am on now.) Now that I’m armed with a little bit of birthday money, particularly a gift card to REI, I’m on the hunt for a new backpack. ...

Two Good Board Games

This is just to record two old games that my family very much enjoys. Both are a wonderful mix of strategy and the luck inherent to board and card games. The rules are reasonably basic, and the boards can be beautiful. They are Cribbage and Backgammon. Cribbage is mainly a card game where you play to 121 points, but traditionally you play on a board with holes and pegs to track said points. It can be played with 2, 3, or 4 players (with two variations in the 3-player version) and is a wonderful game to teach someone starting at a young age. It teaches quick decision making, basic addition, and is just a casual, fun game to play at any point. ...

Geometric Series: The Basics

I was just tutoring someone in their Calculus 2 course, and we did a problem on geometric series. When I was a student, I remember memorizing several facts about geometric series without really grokking the algebraic details of why the formulas you come up with are so nice. Since it is fresh in my mind, I figured I’d go through the standard approach. ...

Celebrating The Fourth

I’ve been thinking about the Fourth of July. During the past couple of years, I’ve become less confident that there’s any agreement what precisely it is meant to celebrate. In theory it’s a celebration of our self-proclaimed anniversary of independence from British rule. Excellent. Yet it more closely resembles a general celebration of whatever America means to each particular celebrant. ...

Marble League 2020

With no sports yet available in the United States, I’ve fallen back in love with the Marble League, a genuinely interesting, engaging, and exciting set of “athletic” events for – you guessed it – marbles. ...

The Gold Standard for Math Typesetting on the Internet

Through a wonderful little game called TeXnique, I became aware of the online typesetting system KaTeX. Unlike MathJax, which is immensely finicky, slow, and has limited support for proper LaTeX, the KaTeX system supports scaling of rendered images, automatically detects the text color of my site and adapts as necessary, and has a fuller implementation of LaTeX commands.

Some Links RE: Protests and BLM

I don’t feel equipped to write more about this right now, but there have been others whose words I would be happy to share; they are not directly from those affected, but instead are from those of similar backgrounds as me. They are mainly from technology podcasts, which I think others are unlikely to share around. Just listen to the introductions of each, and they provide good viewpoints and resources in their show notes. ...

George Floyd, Minneapolis, and Processing

It’s hard to form any words that describe the thoughts swirling in my head with regards to the situation in Minneapolis. I can’t deny the selfish thoughts in my head: A week after I come back to Minnesota to be with family for the summer, this all happens. There’s also the privilege I hold that allows me to sit here and process everything from the safety of my home (or even potentially ignore it if I had a mind to.) ...

Update: Animal Crossing Takes Hold

This is a quick update, as I’ll be traveling over the weekend and don’t have much time to write a longer post. In short, Animal Crossing has captured my mind. It’s a cleverly simple game that lets you focus on whatever grabs your attention. While my initial weeding endeavors have fizzled out, I’m very much invested in trying to obtain every fish and bug I can over time. Fashion and interior decoration don’t excite me overly much (I probably only have about 7 things in my house), but I’m playing the game to get to the point where I can have free reign over the island. ...
