Universal Studios Hollywood family tickets 2026

We recently went to Universal Studios Hollywood and had to figure out which tickets to get. By default, I would’ve just gotten annual passes at Costco and called it a day. Thankfully on Reddit, people discuss the different tickets you can choose from. It seems to me there’s 2 main paths to choose from: 1.) […]

Building a 6 7 image classifier with fast.ai

I recently took Fast.ai’s Practical Deep Learning for Coders (part 1) course. As practice, I used transfer learning to build an image classifer. Given a handwritten number image, the model will classify it as a 6, a 7, or neither. With transfer learning, I was able to fine tune resnet18 against the MNIST database (handwritten […]

Apple Vision Pro Demo Impressions

I tried out the Apple Vision Pro (AVP) hardware in an Apple store today. The ball was in Apple’s court. I really wanted to be impressed by the hardware and put me over the edge to pick one up and develop apps for it. I’ve released Day 1 apps for the Apple Watch & ARKit […]

Updating web app from Rails 4 to Rails 7

A few months ago, certbot gave me the warning “Your system is not supported by certbot-auto anymore.”. With my Rails 4 app running on old Ubuntu 14.04, it was time to update the app & environment. Since I’m using Digital Ocean’s droplets, it was easy to spin up a new droplet, setup the new droplet, […]

Disney California Adventure (CA) Trip Report – June 2023

Our family went to Disney CA on a weekday in early June. I read online there would be lots of graduating high school students, but I didn’t anecdotally feel like the park was filled with students. We opted for 1 day of intensity instead of going to Disneyland over multiple days. Since we haven’t been […]

Installing Windows 11 on a new PC built from scratch

I recently built a PC from parts I got at my local MicroCenter and online. Building the PC was tough, but there were no surprises. Installing Windows 11 Pro was really, really difficult. I’m shocked since installing software (especially a prominent offering of Microsoft) is supposed to be trivial and work everywhere. With my PC […]

How I cleaned up 3M spam comments in a WordPress blog

Tl;dr: delete them. Last week, I received an alert, my blog’s database was too large (> 3GB) and had to be upgraded to a premium plan. Paying a new monthly fee for something I don’t need made no sense, so I looked into the database. Most of the space was used by two WP tables: […]
