Among many of the text-based UIs advantages, I found that the ability to copy-paste almost anything using Vim shortcuts via tmux or the shift+ctrl combo of my terminal emulator is one of my preferred. Here is an excerpt from my long-running (server side) Irssi session, as a tribute to Vim’s creator:

23:57 -A_Dragon(A_D@libera/staff/dragon)- [Global Notice] The Matrix bridge is experiencing continued stability and privacy issues; we have requested it be shut down until they are resolved. Matrix have agreed
          to shut down the bridge no later than 1400UTC on Saturday. Feel free to ask further questions in #libera-matrix

Nushell isn’t exactly a shell, at least not in the traditional Unix sense of the word. Nushell is trying to answer the question: “what if we asked more of our shells?” — The case for Nushell

With recent support for data frames, it becomes an interesting challenger for tiny on-the-fly data wrangling scripts. Beware that it relies on polars-arrow which (most of the time) require a recent stable Rust. Also, if you encounter an E0034 (“multiple applicable items in scope”) when compiling polars-related dependencies, try adding --locked to cargo install. When you’re done, enjoy the power of data frames right into your shell!

With my last timing for processing a 30 Mb CSV file, loading the file in Nu shell is a breeze:

~/tmp> timeit {dfr open ./nycflights.csv}
70ms 682µs 766ns
~/tmp> timeit {open ./nycflights.csv}
1sec 194ms 477µs 961ns

First instruction uses dfr open while the second instruction relies on builtin open command.

Until now when reading my feeds using Newsboat, I was simply filtering unread feeds, sorted by count using a dedicated keybinding (bind-key S rev-sort, which allows me to simply press Su to get the desired output). Now, I learned about l which filters unread feeds. It is quite handy since it acts as a filter and the list of unread feeds empties itself as you read articles.
