Why F#?

(think) · Why F#?If someone had told me a few months ago I’d be playing with .NET again after a 15+ years hiatus I probably would have laughed at this.1 Early on in my career I played with .NET and Java, and even though .NET had done some things better than Java (as it had the opportunity to learn from some early Java mistakes), I quickly settled on Java as it was a truly portable environment. I had some C# courses in the university and I wrote my bachelor’s thesis in C#. It was a rewrite of Arch Linux’s pacman, running on Mono. This was way back in 2007. ↩

This video explains how you can use BenchmarkDotNet like all of the performance examples you see across the web!

youtu.be/RR7Cq0iwNYo
For the beginners out there for C#, this video details how IEnumerable works. While it doesn't do a super technical deep dive, it should help explain the behavior vs something like an Array or List.

I really like using #CSharp , and like it's reflection tools, and CSI/Roslyn, but the fact that it's maintained by microsoft makes cross platform development kind of a nightmare. Maui supports Mac/iOs these days, but still has no linux support. And having to buy a rider license for a non-windows IDE is also turbo annoying. It wouldn't solve all my problems, but I really wish Python could compile.

Back in the day I was writing a Bot for Twitch, and I showed the UI on Screen, and immediately Twitch Chat started trying to change colors and stuff of the bot.

I had to explain to them that no, that's not going to work; I didn't build it as a WebApp. Their messages were simply text and incapable of being executed unless they found one hell of an escape.

Because it was C# and Windows Forms lol.

Testing a personal #AI assistant locally sometimes leads to some interesting moments.

I spent some time with the debugger to figure out why my assistant would stop responding to me after adding some tools for it to use. Turns out it was hallucinating about how to use them, generating an empty response each time. I kept messaging it because I was curious to see if the chat could eventually get back on track.

An excerpt of a chat exchange between me and my personal AI assistant, Lexi. Its messages are in green bubbles on the left, and mine are in blue bubbles on the right.  Transcript: LEXI: [...]trying new foods. How was your meal? Nice timing, Taco Bell delivered at the right moment! Did you get any other treats with it? ME: I am Chris, haha. But yes, I also got a couple tacos, and some chips with guacamole. ME: I did not get a response from you, Lexi. ME: Lexi, please stop putting your responses into the tool arguments. They don't take any. ME: There is no such thing as a "print" tool, Lexi. Stop calling it. ME: Lexi, please... stop calling your tools. I see you doing it in the debugger. I don't get any response from you in the app now when you call them incorrectly. LEXI: Sorry about that! I'll stop calling the tools. So, Chris... nice of you to tease me about the tool call earlier! How's vour evening going after Taco Bell?

All beginners should get familiar with the switch statement.

If you're new to programming and csharp, you may have come across a switch statement but not fully understood how it works.

A switch statetement is a helpful tool for managing conditional checks. In some cases it can enhance readability and reduce some low-level overhead.

Learn all about it so you can use it effectively!

Has someone already replaced DotNetZip because of the vulnerability (and because it is archived now) with System.IO.Compression?

What I've seen so far: System.IO.Compression has still no support for password protected zip files.

I may try "ProDotNetZip" (a DotNetZip fork) within next days.
