I took a few pictures of all the critters I came across walking through a meadow on my way to work. I think they came out quite nice :) #nature #photography

Would you use a program for #macOS that show which processes are listening on which ports?

I sometimes find myself in the situation that a process has not been stopped correctly but can't remember the command to find it.

#mac #dev

Using ariadne (github.com/zesterer/ari...) helped me spot an off-by-one error in my tokenizer! Seeing data structure visualized this way can really help. Check out ariadne if you are into #rustlang.
