Andrej Karpathy’s take on AI coding agents feels grounded. The industry’s chasing full autonomy when models still hallucinate too much.
Agents that churn out a thousand lines of code leave you either blindly trusting them or slogging through reviews. These tools should embrace their fallibility.

It's really amazing to me, a person born in the 90s, that I have a 13" laptop that has 24 CPU cores that go up to 5.1Ghz and 96GB of ram and it weighs under 3 pounds. So easy to take for granted just how far compute performance has improved.

I couldn’t find a decent syntax highlighting library for .NET — so I built one while working on my AI coding assistant CodePunk.

A group of physicists claim they have proof that true randomness exists. This has implications for encryption protocols and computing, but (if true) would also indicate that the past does not determine the present.

`dotnet run file.cs` is coming:
Allows running C# source files with no need for an explicit backing project. We call these file-based programs (as opposed to project-based programs).

Added a way to diff two assemblies at the byte level.
This is what I really needed it for - to debug deterministic builds. I needed to see why is the assembly different even though nothing has changed. In this case it was SourceLink stamping the Git SHA into the embedded pdb.
