Welcome to the future with 50y old technology. There is an obscure emacs extension, swank js, that runs a nodejs daemon that speaks slime to emacs.

It allows you to work with js the same way you'd work with lisp, evaling lines or buffers into a live nodejs instance.

I use it (in combination with org-babel) to talk to live instances of remote services, to inspect data, experiment, but also as kind of an on-the-fly UI

It allows you to inject js into a browser as well, handy for js dev or even on the fly data scraping/web manipulation. Super useful yet not very well known.

here is a quick elisp code to make it run with livescript

10$ power bank / battery charger combo that you can use for day to day stuff but also outdoors.


  • usb in - usb out (was that so hard?)
  • It supports low power solar charging
  • light (30g)
  • they can be chained in series and will charge simultaneously if they get enough power, or one by one if they don't
  • each charger is obviously self contained so no single point of failure
  • on the negative side, it supports 3v rechargeable batteries only
