This is in fact exactly what we (https://www.turbinelabs.io) do. With enough proxy work you can tee some traffic to version Y and observe success rate/latency, then discard the response (or compare it with version X's response), at least for idempotent requests.
dc exists, and is great for quick shell script math. As an interactive calculator REPL it is... not the greatest. Having the stack represented on the right gets closer to the HP 48 experience.
Interesting. From my standpoint (CEO of a company that co-signed here) this isn't money spent. We already have a flexible vacation policy, and this just makes it explicit that civic engagement can be counted against that. Agree that it does amplify the voice of tech as a demographic, which is, sadly, not reflective of the general U.S. population.
The flip side is that a fund dedicated to compensating part-time working minorities to participate in politics would likely be painted as "protest checks". Would love to tease this out more though.
I'm founder of one of the signatories on this, and yes. It will cover engagement that does not line up with my personal politics. This is intended to support engagement, not direct how people engage.
As with all our policies, we're forever evaluating how they "pan out". If it pans out badly we'll adjust.
