minnesota failings

some personally interesting elements from this NY review of books essay by jelani cobb. “In 2019 Minneapolis ranked, according to US News & World Report, among the best places in the US to live, but it was also among the cities with the worst socioeconomic disparities between black and white residents, with a $47,000 gap separating the median household income of the two groups—shocking even for the United States.

damn you vlan 1

scenario you have a switch facing a firewall port and you’re seeing some spurious DHCPv6 hits against the native VLAN despite having no switchport native vlan being set on the trunk interface facing the firewall. a quick look at the link local addresses points at the switches themselves in the network. then you remember that you have cisco switches and that you need to check the most holy VLAN 1. mercifully, the following fixes this broke ass behavior....
