Unfortunately a Java applet, but the guide was interesting (click the “Next” near the top).
EDIT - how does one actually run a Java applet nowadays? Which browsers still support that integration?
cd $(mktemp -d)
wget http://will.thimbleby.net/misc/misc.jar
wget http://will.thimbleby.net/misc/bootstrap.misc
java -jar misc.jar
And then it drops you into a repl. (Add `rlwrap` in front of `java -jar` if cursor movement doesn't work correctly)Note to self: if I wanted to distribute Java malware to the HN crowd this is exactly how I would do it: write a minimalist, nerdy topic that requires an applet to run, knowing that my audience will happily find a work-around, like the above.
But your reminder is good for the newcomers around I guess.
