Hammerspoon: Switch layout when USB keyboard is plugged in
local usbLogger = hs.logger.new('usb', 'debug')
function configureKeyboard(data)
-- Uncomment the "usbLogger" line below, plug in the USB keyboard and update the USB vendor and product ID
local isKeyboardAffected = data.vendorID == 9610 and data.productID == 89
-- usbLogger.df("eventType %s, pname %s, vname %s, vId %s, pId %s, keyboardAffected %s", data.eventType, data.productName, data.vendorName, data.vendorID, data.productID, isKeyboardAffected)

Node.js: Create checksums for npm's 'postinstall' actions

Node.js: Create checksums for npm's 'postinstall' actions

After watching Patrick Debois' talk from DeliveryConf »How Secure Is Your Build / Server?«, I tried to get at least a rough idea if postinstall steps where running at all and if they do the same things after a package update.

So I wrote a little proof of concept that will:

  • Create a Dockerfile, using package.json and package-lock.json from a Node.js project in the current directory
  • Install all its dependencies inside the Docker container first, without running any postinstall steps, then do the same with running the scripts.
  • Reading the diff of those steps using Docker's image layers
  • And calculate a checksum of those changes.

I'm using the git pr command from the git-extras toolset to check out a local copy of a PR.

To rebase the PR again, I wrote a little script, which needs to be run in the PR's branch:

#!/usr/bin/env bash

branch=$(git symbolic-ref HEAD --short)

git rebase master
