Wrote my first
#Rust program today. A small utility to grab the last value of a matching column in a matching csv file. I had hacked something together with #qsv, #nushell and #python, but those were all too slow for fast repeated calls. This Rust version executes 10-100x faster: a few ms on a
#RaspberryPi 4, neat! 👌
Rust and
#nix is also a match made in heaven, omg is the experience better than Python 🫠

Nushell Niceties: Checking If Value Is In List Or String Or Key In Record
A blog by @mrhaki
Nushell has the in operator to check if a value is an element of list. With the same in operator you can check if a string is a substring of another string. And finally you can use the in operator to check if a key is in a record. When you use the operator the value you want to check is defined before the operator and the list, other string...
#Nushell 0.111.0
https://www.nushell.sh/blog/2026-02-28-nushell_v0_111_0.html
Highlights:
* Updated `input list` command: select menus are smooth now and there are some really useful new flags along the way
* Aliasing now works with parent commands (type polars less now)
* Users can (finally!) use `finally` after `try .. catch ..`
* Change `let` to allow assignment values to be passed through when `let` is used in the middle of a pipeline
* Experimental cross-platform native clipboard: new `clip copy` and `clip paste` commands
