This is the after (deregulation by @fedesturze and @JMilei) vs before regulations to export Argentinean wine. No wonder Chile exports 3x more until now!

So more @grokipedia fun: C# history. It added useful info missing on @wikipedia (Ximian then Xamarin entirely absent, white image), until I hit that "C# 13 is latest" (vs C# 14 original). Then I looked at the edits and my mind was fully blown. It wins hands down on accuracy!

Driving the new #dotnet agent framework from TOML configuration is soooo satisfying!
All it takes is one line:
var builder = WebApplication.CreateBuilder(args);
// add config sources
builder.AddAIAgents(); // 👈
Give it a try: www.nuget.org/packages/Dev...

I really really really don't like long strings embedded in my C# code. In agentic AI development (with the new Microsoft Agent Framework), this is even worse since agent instructions/descriptions can be lengthy, and it makes absolutely no sense to build/reload an app just to tweak them

If I was @Microsoft and owned @GitHub, there's no way I would let this be the status quo of #Windows performance. It's a DISGRACE and makes the whole company look laughable. How can Microsoft's own product be the WORST in his own dev/CI platform?!?!

Pretty wild to see my reported #dotnet issue github.com/dotnet/exten... fixed by #copilot in github.com/dotnet/exten... after close interaction with @stephentoub. Wild times.

Free speech is for protection against the *government*. You can be fired by your employer and that has nothing to do with free speech IMO (i.e. misaligned values). The VP said as much too. And Pam Bondi should resign.
I don't recall Trump ever being (or even promising) to be a fiscal conservative.

My first job as a teenager was marking up prices at a supermarket in Argentina (owned by a friend's family). Every day. Layers upon layers of new prices. Thanks to a democratic socialist party which doesn't know printing money doesn't create prosperity. I was 15yo.

#grok knows the best way to calculate things is writing some code and running it, rather than dumb token prediction. @xai is kicking ass. I love that they ditched the "Deep search" and "Think" buttons in favor of Just Working.

You can clearly tell @AWS was created in an era where @dotnet #SignalR didn't exist. I feel like I have to manually refresh everything in the console every now and then. Feels like a 2000's web app. @Azure is soooo much better in this regard. Everything is instantaneous.

The "elicitation" of user input from #MCP in @code is pretty sleek. Here I moved the LaTeX rendering preferences to user input if not set (via env/config), from first tool run to successful render. Sleek as hell, and in a trivial single-file @dotnet run .cs!

The Law by Frédéric Bastiat (free with your @spotify premium) is an eye opening book. If you think lobbies by vested interests sounds fishy, you owe it to yourself to listen to it.
And this quote is a pretty accurate summary of the core idea.

Bold, bullish prediction from Morgan Stanley on the "rapid expansion" of the Waymo (and Zooks?!) fleet in the next 5 years.
I wonder how Tesla is ever gonna catch-up given they produce that many Model 3/Y in the US for 1/4 the price each every ~4 DAYS 🤭
