Rust is verbose so it’s not really that impressive. I’ve put it aside for some time and was toying with local inference, LLMs, writing agents and my attention was…

C# strings silently kill your SQL Server indexes in Dapper
If you're using Dapper with anonymous objects to query varchar columns, you're probably sending nvarchar(4000) parameters — causing CONVERT_IMPLICIT on every row and defeating your indexes. Here's the fix.
