.NET Annotated Monthly | July 2021
Did you know? Microsoft created a C based language named C# in 1988? 1988!? You heard that right! It’s true! This language, of course, was not the C# that we all know and love today. Meanwhile, Rico Mariani says in that same article that the code name for VB version 1 was named “Thunder”. Befitting.

This advice should work for many people. For those who don’t want to completely rewrite existing projects, building the same kind of software as the original project may work.
I’ve found that teaching myself new programming languages is 10x easier and faster when I do so in the context of rewriting an existing project (vs. starting a new one). There are fewer unknowns. There is a clear roadmap. It’s mostly googling for “do <thing I know> in <new lang>”— Jared Palmer (@jaredpalmer) June 1, 2021
Since this month features F#, perhaps, dear readers, you should try it out too. A quick twitter search revealed several tweets similar to this where folks said that they really enjoy F# and find it useful, fun, and easy.
It’s been so fun writing fsharp for a prototype. Technology isn’t just tools, it’s the people who use them more than anything. I got help from tons of people and was able to largely put together a full stack prototype in a couple long nights. If ur on the fence, just try #fsharp.— Gina Marie Maini (@wiredsis) June 24, 2021

Has this happened to you? Perhaps not with a desk but other items? I think more of us can relate to this than want to admit.
So I bought a standing desk, and this whole standing thing doesn’t work for me. I’m now looking for a very very tall chair so as to justify having bought a standing desk.— Hadi Hariri (@hhariri) June 9, 2021
This is exactly how it feels, Richard.
