Re:Show HN - Client-side Google Analytics without using cookies

Good catch. GA added this after we came up with our solution. We are using custom Javascript code that uses Measurment Protocol to send data to GA.
EDIT: Client Id still needs to be generated for Google's Analytics.js. In my experience, the approach we took for that works quite well without using complicated browser foot-printing.
Edit: I guess this is what the OP's link is actually using.
