Pharo 9 will also be available as a Linux package in several major distros! https://thepharo.dev/2021/04/09/installing-pharo-in-linux-using-the-system-package-manager/ For most languages this is no big deal, but it's much harder for a deeply mutable image-based environment.

Pharo 9 refactoring demonstrates some clever analysis: if you extract a method from an expression, it can find other occurrences of that expression in the class hierarchy! https://pharoweekly.wordpress.com/2021/04/01/pharo-90-refactoring-support-improves-steadily/

A clever approach to JS dependencies during development: Snowpack hosts npm libraries which you can reference directly!

TIL you can return values from loops in Rust: https://doc.rust-lang.org/reference/expressions/loop-expr.html#continue-expressions I've only ever seen this in Common Lisp / Elisp!

Renaming code often exposes further needs for refactoring: https://www.fluentcpp.com/2021/04/23/make-bad-code-look-bad/ (I found the example really compelling!)

It's amazing how quickly leaked credentials get harvested and used to create VMs mining cryptocurrencies: https://johnmathews.eu/i-leaked-credentials-onto-a-public-github-repo.html

TIL that &mut [T] in Rust means that you can modify the items in a slice, but you can't change its size. It's surprisingly handy: I'd just been using &mut Vec<T> everywhere previously.

Why Lisp? It has its pros and cons.

This is the most creative form of Linux usage I've seen in ages! From

The number of tools a programming language is expected to provide is growing over time. This in-depth article describes what Rust provides: you can't just ship a compiler these days. Source:

Want to move to a code autoformatter, but worried about git history? Black even documents how to teach git to ignore your formatting commit!

Spectre vulnerabilities remain a problem in browsers, and the PoC even works on new Apple silicon!

Python programmers use Linux significantly more than Mac or Windows, and Windows usage declines with experience level: https://www.jetbrains.com/lp/python-developers-survey-2020/#DevelopmentTools

It's not easy to display a log file nicely in a browser. The file might be huge. Users expect to be able to link to lines. It might have colour or control codes. I've been pretty impressed with the GitHub actions UI, compared with other CI tools.

A 9V battery with wi-fi, so it can notify you when your smoke alarm is activated: https://getroost.com/product-battery.html I'm not sure I'd ever buy one, but it's an innovative way to build a noninvasive integration.
