Learning a language ever lasts. Here are two phrases I learnt over the last weekend.

• X is the new black → X is the current trend.
• It feels like preaching to the choir → Needless to say.

These phrases come from an article which describes io_uring.

I enjoyed reading the article. The article helped me to get an overview of what io_uring is trying to solve. But on the other hand I felt that using these phrases makes the article difficult to understand unnecessary for people who use English as a second language. Is it a reasonable expectation for people who want to understand technical things also need to understand these phrases?

I’d say no.
