One of my mentees, Raissa, has started writing blog posts about what she’s learning with C#, with the goal of becoming a C# developer. If you’re just starting out with C# (or simply curious), you should definitely check out her 'Hello World' post 👇 rlimondev.substack.com/p/hello-world

Hello World!
Writing “Hello World!" as your first program is a long tradition in programming.

I've been mentoring a select group of young, motivated women who want to get into the field. Seeing their hard work, perseverance, and motivation, just like I had when I first started learning, is lovely.

I keep thinking I've finally figured myself out. Then life reminds me I haven't. Rethinking and relearning how I function in my twenties isn't easy, but it might be one of the most important things I'll ever do.

All the Michael Jackson songs being back on the charts makes me want to buy a vinyl player and steal all my parents’ MJ records. It’s so good.

How much money do you spend on AI subscriptions? I'm at 20 USD a month but I feel like a lot of developers spend way more than that.

10 talks. 15 blog posts. 3 mentees. Another year on the .NET Foundation board. And, most importantly, another year of caring for and contributing to this amazing community. MVP renewal submitted. Here’s hoping for year 4 as a Microsoft MVP ✨

Vibecoded a simple React Native app with GPT Codex to track whether or not I need to check / water my plants ☘️💦 All plant apps in the play store are way too much.
Mobile app screen titled “Plant Watering” showing a “My pots” section. A weather card displays “Max 18.4°C • Precipitation 0 mm.” Below are multiple pot entries with status labels marked “Checked.” The first entry is “Pot 50x50,” planted on 04-21-2026 with 4 plants, noted as already checked today. The second is “Pot 42x50,” planted on 04-23-2026 with 6 plants, also already checked today. The third is “Pot 30x30 L,” planted on 04-24-2026 with 3 plants, already checked today. A button labeled “Add pot” appears near the top.

Dat is de afweging. Ik ben ook zeker niet van plan om te kappen met in het Engels schrijven hoor haha. Maar met de hulp van AI een Engelse blogpost herschrijven in iets wat meer mijn toon is zou een uitkomst kunnen zijn voor sommige mensen.

I’ve realized C# is just too concise. I’m craving more words. Today, I begin my journey into Visual Basic. Finally, a language that understands my need for 'End' 'If' and 'Then' statements.
