Code

I originally wrote the C# version of this code to write a performance tuning tutorial for DateTime parsing. I came back after learning some Rust to try to compare the performance of the two languages.

I do the laundry in our house, and it often takes most of a day because I don’t hear the dryer finish. I set a timer on my phone, but it’s often not done when I go check on it. Today Darinee and I finally implemented a “Dryer is done” notification on my phone, so I’ll know exactly when it’s...

We recently set up Wireguard as a home VPN. It’s widely used, trusted, open source, and free, but I stumbled on a few things along the way and the documentation is sparse, so I wanted to write up what I did.

Editor’s Note: This is the first guest post from my wife, Darinee!

You’ve got some existing code and you might want to make it faster. How hard is it to make it faster? How do you go about it? What tools do you need? Is it even worth doing?

I love the Visual Studio C# Performance Profiler, and am shocked to find out how many engineers around me haven’t used it before. It’s very easy to quickly check the performance of your code and you’d be amazed how often there are significant performance bottlenecks there that are very easy to fix.

I’ve been using FFMPEG to transcode gaming videos often lately, and I find the reference documentation confusing.

Today I’m releasing a new version of Regex Builder, 14 years after the previous release, thanks to an email from a fan. Regular Expressions (regexes) are a powerful way to search text, but also hard to write and very hard to debug, kind of like SQL queries. I wrote Regex Builder originally around 2004 (!!) to help me...

This blog is hosted on CloudFlare Pages with CloudFlare-managed DNS, and I finally have DNS resolution working fully. The documentation was confusing and incomplete - here is what I needed to know.

I recently decided to make a local and second-cloud backup of our digital photos, and decided to see if I could optimize them in the process. I figured our phones would produce decently optimized JPG photos directly, but it turns out that a quick pass with an optimization tool reduced the sizes by half with no difference that I could...
