    The first robot across the finish line, Tiangong Ultra – created by the Beijing Humanoid Robot Innovation Center – finished the route in two hours and 40 minutes.

    The winner of the men’s race on Saturday finished in 1 hour and 2 minutes.

    What a misleading headline. This was a 13 mile race. The robots lost by about 8 miles.










  • Every company I worked for is like this. I sneak small improvements into daily work. If I call an old function, I’ll often fix it while I’m there. Don’t raise tickets. Don’t ask. Just fix it.

    I also have a shelf of a hundred fixes that I never merged. I’ve done the work, but the real hurdle is PR and and testing. It takes days of effort to push code that took an hour to write.




  • I’ve got 3 subnets on an L2 switch. You will have clashes over DHCP if you have both broadcasting on the same L2 switch without VLANs.

    My guest wifi is on a vlan, but the switch is L2 and it’s fine. The router has separate physical ports for each subnet. The “guest” subnet is only accessible over Wifi, and the access points are configured so that the guest VLAN is mapped to a separate SSID.

    My third subnet has no VLAN. It’s IPv6-only and all devices have a static IP address. It’s only used for security cameras. I did this so they don’t transmit on the same physical cables as my primary subnet. It is otherwise insecure, as I can join the subnet by simply assigning myself a static address in the same range.

    Note: There is a bug in Windows where it will join an IPv6 subnet on a different VLAN. I had to tweak my DHCPv6 / radvd so that Windows would ignore it. Yes, Windows is this dumb.
