Great discussion about "new" async/await in .NET with Andy Gocke from the .NET team! A lot for me to read and dig into the new implementation - github.com/dotnet/runtime/bl…

Congratulations @dotnet team! We have been running bing.com on .NET 10 builds for a few months now and we love the latency savings 🙏🏾

.NET 10 ships in a few hours. I’m very excited about the release. 10 years ago a few of us got pulled into a room to spike the first version of a new cross platform, open source .NET. We’re 10 years in and extremely proud of how far the product has come.

What do @MadsTorgersen & I share
(besides a love for curly braces)?
Turns out, something that is a feature, not a bug.
And it's called ...👉 #ADHD.
In the pilot of #SharpAndUnfiltered, we talk the back and forth to clarity, symptoms, and superpowers.

.NET STS releases now supported for 2 years instead of 18 months starting with .NET 9 (the current STS). STS releases now go out-of-support on the same day as the previous LTS release. Upgrading to an STS release will no longer cause you to lose support!

so i'm a regal unlimited guy and all the summer blockbusters are basically fine, but i probably did enjoy these 4 horror films (and naked gun) more than anything so far this year.
1 Aug 2025
How rare is it that since the 2nd weekend in April the 4 best rated movies are all horror? @SinnersMovie at 97%, #FinalDestinationBloodlines at 93%, #Together at 91% and #Weapons 100%. @warnerbros has 3 of them. Incredible.

like final destination wasn't exactly original but it was FUN and well execute. together, sinners, and weapons are actually kind of ambitious and weird and original

One of the world's two best interviewers interviewing the other
9 Jan 2025
I hassled @tylercowen about why he doesn't expect explosive economic growth from AGI. How could we possibly add 100 billion extra workers and only get 0.5% more growth?
Also featuring Stalin's library, EU decels, and how Churchill was an underachiever.
Hilarious and provocative throughout.
My 4th interview with Tyler. He surprises me every time.
Enjoy!
