Having just moved back to Maryland after 23 years in Dallas, I think I can bring some insight as to Texas' merits vs. Maryland. ("A Texas remedy for what ails Maryland jobs," June 22)

What does 'idiomatic' mean in Rust? Like many here, I even have some (false?) confidence that I know what idiomatic means.

Three Questions

Let me ask three questions:

1. Who gets to decide what is idiomatic?

2. How does something become idiomatic?

Here I hope to make it easier for people to find an authoritative definition for the meaning of an ISO 8601 profile. To be clear, this doesn't mean the definition itself will be simple or clear. Sorry.

I was able to find the document below by way of this [English Language & Usage StackExchange][1] post: [What does it mean for RFC 3339 to be “a profile of” ISO 8601?][2]

Hiding macOS Icon Files

If you customize a Finder icon, macOS will put an Icon file in that directory.

While ls -al will show the filename as Icon?, the real file name is Icon$'\r', which can be found using Zsh's autocomplete functionality. Yes, the last character is a carriage return. Why, you may ask. That's a fair question.

Anyhow, to apply the hidden flag to all icon files located recursively within the current directory, run this command:

find . -name Icon$'\r' -exec chflags hidden {} +
