  • You like deploying infrastructure, probably in a cloud environment, but you don’t want to push a bunch of buttons in their web interface, so you use Terraform to declaratively define the things you want, and it goes and builds them for you. Super useful for when you need to build resources often, to detect and correct config drift, and get started down the path of Infrastructure as Code.







  • I’ve actually done this for a Microsoft owned IP before. Someone was Wordpress-scanning a particularly fragile application of one of my clients (which was not Wordpress) which was causing it to fall over. The scan stopped within an hour of sending the abuse email.

    Edit to add: I used to work in a NOC for a tier 1 ISP. We had an “abuse department” (a couple people) that investigated these and opened tickets with the NOC. I’ve emailed customers and disconnected circuits as a result of abuse emails, so I wouldn’t say they’re totally useless, but I’m sure it depends on the company involved.









  • Couple questions:

    • What’s your ISP at home?
    • What’s the ISP of the remote IPv6 server?
    • Are the other networks you’ve tried from the same or different?

    I’d start with traceroute and see how far your IPv6 traffic gets before it fails. It could very well be some peering or routing issue between some of the ISPs in between you and wherever that IPv6 address lives. If this ends up identifying where the traffic dies, a lot of the tier 1 ISPs have BGP looking glass servers so you can get an idea of what they know about that subnet.




  • Here’s what I did for humidifiers in my house:

    • Dumb, analog-controlled humidifiers (like with the knobs, no digital displays, buttons, modes, etc)
    • Local control smart plug (Tasmota flashed Sonoff S31 in my case, but it can be anything)
    • Humidity sensor (I use the Zigbee Aqara ones)
    • Create a Generic Hygrostat entity

    Now you’ve got a smart humidifier in Home Assistant. You can set the desired humidity, and when the sensor detects it’s below this, it’ll kick on the smart switch. When it passes the threshold, it’ll turn off. It’s been great! My humidifiers shut off when the water level drops, so I can even use the power monitoring in the Sonoff switch to send me a “low water” alert when the humidifier should be running, but it’s drawing no power!
