I need to get a c# async/await based program to get much faster. Profiling this code feels undoable. The callstacks are super deep with previous async sections on the callstack. How do people profile their async/await?

Counting Crows!

Some good examples of recent c# async/await drama: blog.s-schoener.com/2025-09-22-asy… Do all async/await people just live like this?

whoa so much ai news. so much stuff is launching, the hardest part is choosing which if any to give a shot. takes so long to actually evaluate/learn a new model/product/tool.

n=1, but new claudecode just did a really good job on a gnarly protobuf parsing bug

my biggest fear is writing some question for chatgpt into the groupchat by mistake.

all LLM's seem to think you can create a ReadOnlyMemory from a ReadOnlySpan

I was tired of AI coding for a while, but the new claudecode has me back. it feels a big step up. Using it a lot to find bugs and do investigations in addition to coding. it's finding a lot!

Not being allowed to have >1 Span<T> to operate on drives me crazy. I want to take N input spans, do some operation on them an output a single span.

TIL JetBrains.Annotations has [InstantHandle]. You put it on a method parameter that's a delegate to promise you'll invoke it immediately, and not later. helps squashing annoying warnings at the callsites! where have you been all my life.

Just learned that semaphore is “traffic light” in Spanish.

I need an agent that can find old invoices my taxguy is asking me for across 3 email accounts / websites.
