Simulate network chaos on macOS
# Simulate a fairly realistic "bad network" (e.g. bufferbloat,
# flaky Wi-Fi, LTE from a brick building) to help find bugs
# in code that never expects network responses to arrive out of order.
# Run with `sudo ruby network-chaos.rb` and stop with control-C.
# Test with:
#
# $ ping 1.1.1.1
# PING 1.1.1.1 (1.1.1.1): 56 data bytes
# Request timeout for icmp_seq 0

Hi ███████,

Somehow your other emails didn't register, but I did want to write and let you know that I'm not interested. Thanks for writing though, I do appreciate that I made it through your filters.

The reason I'm not interested in working on Alexa (and other similar IoT devices) is I think they are irresponsible outside of narrowly bracketed vision-impairment accessibility situations. The trade-off of privacy for convenience is only really possible for specific groups of very privileged people.

More generally, I don't think Amazon treats its warehouse workers very well, and I would feel bad being complicit in their continued mistreatment. The HQ2 effort to minimize tax exposure, followed by public statements by your CEO about how he's deciding how to spend his "winnings" would make me feel ashamed to call myself an Amazon employee.
