i loved seeing the moment of stone realising he was going to stick with robotnik (─‿‿─) could we see the moment ROBOTNIK realises stone is here for good?

Robotnik isn't used to people being happy to see him

[cosmogyros]

That moment when you have to let people be wrong about you because correcting them would make you seem like an unbearable show-off

I was at a bookstore with a friend the other day and I was looking at a book in German that I was interested in buying, but then I saw that it was a translation and had originally been written in French

I commented idly to my friend "Sometimes I don't buy a book because it's a translation and I always prefer to read in the original language when possible" and she said in an agreeing-with-me way, "Yeah it would make more sense to read it in English"

and I realized she assumed I meant English when I said "original language"

but I couldn't bring myself to say "Yeah, or French or Dutch or Spanish or Italian or Portuguese or one of the other languages I read..." because like. who says that kind of thing.

my colleague doing literally everything with chatgpt drives me insane

[lbhslefttiddie]

me: we should get into hydrology or ecology or something geography related. we are good at geography and love stupid bullshit like that. its a viable career path with lots of options and historically speaking people do tend to be happier when they can afford to eat

also: okay but have you considered. going all-in on creative writing with a focus on programming and music design so that you could spend all your time creating video games in a basement somewhere

me: no i think i would like to have a stable income i think

also me: forsake everything to get into that interactive fiction course right fucking now

Robust tooling – especially with Visual Studio and JetBrains Rider

Active improvement – backed by using Microsoft and open-source community

Challenges and Considerations

Learning curve – particularly for beginners due to its giant atmosphere

Legacy framework – older .NET Framework tasks aren't like minded with .NET Core or more recent variations without migration

Platform differences – sure APIs or libraries might also behave in a different way throughout operating systems

Getting Started with .NET

To begin growing with .NET:

Install the .NET SDK from the legitimate .NET internet site.

Create a new project: Use the dotnet new command or Visual Studio templates.

Write code: Develop your logic the usage of C#, F#, or VB.NET.

I am not dead just severely busy! Days 74-109. I have so much to talk about this time!

So at work (Can't show that due to NDA) I've been bug chasing, and ultimately having to restructure many classes and methods to make one function work as intended.

Then for my C# final I'm still working on my .Net Maui project I finished the journals implementation, and added the event reporting function. I added the events to the journal entry for the day. If there are no entries yet it makes one. I am going to be using the library of microcharts that were used in xamarin (before Xamarin got depreciated into .Net Maui) now it can be used for .Net Maui. I'll be capturing data gathered in the journals to display on graphs to track progress in sleep disorders. At a later time I'll be getting it set up to grab information from sleep tracking apps on mobile.

In C++ my final is to make a game. I am making an adventure game where you can explore a village. It has lore, Easter eggs, and fun imagery (it's a console game unfortunately can't do Unreal). I have to change the code a bit but it has been fun to code!

I might have a contract role coming up for another game studio, so that's exciting.

My plans for the next few days is to get some functionality on the statistics tab in my Maui app, and get my C++ project more put together. At work I'm waiting on the senior dev to plan out how to fix the massive problem we have.

What is Black Box AI?

Black Box AI refers to AI systems that make decisions without revealing how they arrived at those conclusions, making it difficult to understand their internal workings.

Is it going to take the jobs of programmers?

Black Box AI may automate some routine coding tasks, potentially reducing entry-level programming jobs. However, it will also enhance productivity for experienced programmers and create new roles in AI ethics and oversight. Ultimately, while it will change the nature of programming work, it is unlikely to eliminate programming jobs entirely. Adaptability will be essential.
