  • If you’re trying to avoid a whole zigbee or zwave network, Govee makes some inexpensive battery-powered bluetooth thermometer/hygrometers, and have a HA integration, but bluetooth can be tricky to get running on Pis. I feel like most of the actual wifi devices are phone-home type setups. My govee thermometers have pretty good range - one of them even reads from inside the refrigerator.




  • It’s even easier with digital broadcast. I finally had to give up my PCI tuner, because who puts PCI slots on a modern mobo? $25 will get you a USB TV tuner capable of getting all the OTA and cable channels. I used to get, like, 7 analog OTA channels - ABC, CBS, NBC, PBS, and a regional independent - but I get 30 digital. All the majors have added 3-5 channels of SD reruns or other filler. I mean, it’s mostly shit, and the only thing I actually watch is local news, but for a one-time $25 cost, it’s a great supplement to streaming.

    My biggest problem with MythTV is it doesn’t interface with streaming, so I use Kodi on the frontend to source from mythtv, netflix, hbo, or whatever.





  • This is an old post about ipv6, but it inspired me to go looking, and I wanted to share my findings.

    1. for globally routeable IPv6 addresses, probably do let it happen automatically, either direct from the ISP, through the router by prefix delegation, or your own implementation of prefix delegation.

    2. for devices you want to access, internally, create a ULA within the fd00::/8 space, and assign numbers (and names) however you like. Translate all your 192.168.x.y IPv4 addresses to fd00::x:y and go. Only limitation is you won’t be able to access those devices, using the ULA, from outside your network.

    3. you can do both of these on the same subnet, and devices pick up both addresses then use the global address for internet and the ULA for intranet.

    That means you can do dhcp, dynamic DNS, private domains, and all the stuff you know about IPv4 for IPv6, and still do all the stateless autoconfig that “they” want. Some devices, like my android phone, never played well with dhcpd6, but immediately preferred IPv6 as soon as I let them SLAAC.

    If the prefix assigned by the ISP doesn’t change, then device SLAAC address shouldn’t change, either, because they’re calculated from MAC, so if you need to access some internal devices from the internet, you have to mark that address, but (IMO) marking the full address is not that much worse than marking the prefix and remembering the device number.




  • Yeah, I think it really depends on use case. Like, I’m trying to imagine what aspect of my home lab could go so wrong, while I’m out of the house, that it would need fixed right away, and there’s nothing. I only leave my house for work or maybe a week of vacation, though, and I can imagine someone who’s occasionally away from home/house for 6-month deployments, or has a vacation home they only visit four weekends a year, might want more extensive remote maintenance. I’d still want to do that via ssh or vpn, but that’s me.




  • IPv6 does have private spaces. Any prefix beginning with fd is ‘private,’ and (IIRC) there’s a formula to generate the next 40 bits of prefix to minimize the chance of intersections. i.e., you can generate your own internal /48 functionally equivalent to 192.168/16 or 10/8

    Don’t know if you can use that with SLAAAC, but it works if you run a dhcpv6 and makes ipv6 feel a lot like ipv4. You have to NAT everything inside &c, but if you already have a functioning internal IPv4 network, IPv6 is just a matter of figuring out which config options need to be changed (eg, dhcp6.name-servers for option domain-name-servers)


  • Definitely agree for a single install. If OP has a bunch of these installs to do, then editing an install USB to configure networking and enable sshd might be worth the effort. Do the install over ssh and hope the machine starts up as desired, but even then, if it doesn’t just magically appear on the network, he’s going to need a monitor to see where the startup failed.

    Raspberry Pi’s disk imager will let you pre-configure networking, accounts, and ssh, so you just write the image to an SD card, plug it in, and go. That’s a great solutions for systems usually meant to be headless and removable media. If OP’s client hardware allows, he could plug in the M2 or SATA drive meant to be the server’s startup, install Deb there, and. transfer to the server hardware. That’s definitely more work that just swapping the keyboard & monitor, but it accomplishes OP’s stated goal. (Otherwise, a lot of this thread follows the linux meme of “How do I [X]?” “[X] is dumb, do [Y] instead.”)




  • The crash of 2008 is just 15 years ago. You could hardly give away properties in my neighborhood - there were multiple sales for less than the cost of my car. Those exact conditions may not recur, but speculators always, always overextend. The 15 years of continuous gains we’ve experienced since 2008 are historically unprecedented, so one might even guess that we’re due for a major correction. Maybe it won’t be for another 10 years, but there will definitely be a major housing crash “in our lifetime.” Unless, maybe, you’re already 80 years old.


  • Taxing property doesn’t really work, because landlords just pass those taxes on to their tenants. Even if you make a big differential between owner-occupied and rental property (and homestead exemptions are already common), there’s a huge base of people who are either short-term residents or lack down payment, and will rent regardless of how much of the landlord’s taxes they have to pay. You can make specific neighborhoods or communities unappealing to landlords, but that just makes them move across the street.

    One of the things that makes rental property attractive is the massive leverage available to speculators. You can easily get 5:1 leverage on a property - i.e., you get the profits on a million dollar investment for just $200k cash. Interest on the loan is low, because it’s backed the the property, and that interest is tax deductible, and there’s many ways to disguise profits or offset them with management expenses. Maybe there’s things you can do in the income tax code to discourage property rental, but it’s not going to be taxing the property directly.


  • I’m going to talk about lunch.

    I used to pack a lunch - nothing fancy, just a couple of sandwiches, & maybe fruit - then cook dinner, all for around $100/week. Started treating myself to bought lunches. Again nothing fancy, mostly fast-casual type places where you order at the counter & they bring your food to the table. Water not soda. Restaurant lunches are cheaper than restaurant dinners, but they’re also way more calories than my packed lunches, and I found I wasn’t in the mood for big dinners anymore. In the end, I was still spending around $100/week, eating out 5 days/week, and just having a snack in the evening.
