Sometimes programming tools are so good that you miss them when using other languages. I see these mentioned the most frequently: * IntelliJ (for Java) * Slime+Emacs (for Common Lisp) * Pharo (for Smalltalk) I'm struck that they all have bespoke UIs.

Today I learnt that the original name for DOS was QDOS, for "Quick and Dirty Operating System"! https://en.wikipedia.org/wiki/DOS#QDOS (Seems rather unfortunate that they dropped the Q.)

TIL Tcl has a notion of 'safe interpreters', a mode where you can run untrusted code in a sandbox: https://www.tcl.tk/man/tcl8.4/TclCmd/safe.htm Not many programming languages have this, but it's way safer to include in the implementation than try to build as a userland library.
