My CO2 sensor has dramatically changed my routines. My space isn’t small - maybe 1200 square feet/100 sq m - but it must be pretty well sealed, because I can easily see my own breathing add to CO2. Nevermind cooking on the gas stove. Treadmill time adds 500+ ppm.
Now, I open windows every chance I get (which isn’t super often, because the dewpoint is 70 oF/20 oC in Atlanta), and I’ve shifted a lot of my cooking to an electric tea kettle, hot plate, and toaster oven.
I have isc-bind running behind pihole so network clients can register their own hostnames, and as near as I can tell, that’s outside the scope of pihole’s DHCP and dnsmasq. Pihole alone is probably fine if you only want to name static hosts, but (I understand) Unbound doesn’t support ddns, either.
pihole, in front of my own DNS, because it’s easier to have them to domain filtering.
mythtv/kodi, because I’d rather buy DVDs than stream; rather stream than pirate; but still like to watch the local news.
LAMP stack, because I like watching some local sensor data, including fitness equipment, and it’s a convenient place to keep recipes and links to things I buy regularly but rarely (like furnace filters).
Homeassistant, because they already have interfaces to some sensors that I didn’t want to sort out, and it’s useful to have some lights on timers.
I also host, internally, a fake version of quicken.com, because it lets me update stock quotes in Quicken2012 and has saved me having to upgrade or learn a new platform.
If you email to people on gmail or outlook, won’t Google and Microsoft still end up with copies of most of your mail?
Ditto on hardware raid. Adding a hardware controller just inserts a potentially catastrophic point of failure. With software raid and raid-likes, you can probably recover/rebuild, and it’s not like the overhead is the big burden it was back in the 90s.
Once you have a microcontroller running things, adding new features is just a matter of software. Doesn’t add to the BOM, doesn’t complication production in any way. There’s almost no marginal cost to techify everything, and the people who don’t want those features can just not use them. The small minority of people who want a repairable car that they can understand and maintain in their own garage are undesirable customers who reduce after-market revenue.
In the US, plug-in hybrid is a decent way to cover the breadth of consumer desires. Get a battery big enough for 50 miles of daily commuting, but have the ICE for 500 mile holiday trips. More complicated, having both power systems, and you still have the tie to gasoline, but you don’t have to lug a massively oversized battery pack everywhere you go and you still get most of your transportation energy from the electric grid.
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.
Coffee all morning, because sleep. Iced tea all afternoon, because Atlanta.
I was listening to some pretentious film critic yesterday complain that modern films have stopped being artistic or intellectually challenging, because there’s a huge audience of people who are exhausted all the time. They don’t want media that makes them think, that challenges their assumptions, or even requires their full, sustained attention. Comfort media, like mac & cheese for the brain.
Fallout has become exactly that - some vague, nefarious organization as antagonist; raiders & feral ghouls as unambiguously bad cannon fodder. Just move it to a new city, put in some iconic landmarks, and let the money roll in. I can’t honestly think of a franchise that gets past 2 without falling into that trap, but I just started another run through FO4.
I just don’t like my logs filling up with scripted login attempts. Even with fail2ban, for a while there I was getting 100+ login attempts every day, and it upset my sense of order.
This is an old post about ipv6, but it inspired me to go looking, and I wanted to share my findings.
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.
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.
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.
I do ssh because I’m more comfortable with it: it’s ubiquitous and as close to bulletproof as any security. Put it on a nonstandard port, restrict authentication to public keys, and I have no qualms.
Heh. House I rented was built before ubiquitous electricity. At some point, someone slapped a fuse box on the outside of the back wall and drilled a bunch of 1" holes in said wall to pass wiring. House was built on piers, so they just dragged wires around to places where they wanted outlets, which were mostly planted in the floor. Not a ground wire on site. I have no idea how they got away with renting that out, but it’s not like I called code enforcement, either.
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.
fd00:: is the new 192.168

My brain definitely focuses better with environmental cues. I mean, I can work just about anywhere, but if I’m not in the mood, then having the environmental cues displaces alternatives. Subjectively, I feel more productive at work. Never had a really bad commute, so I was never motivated to try to set up a ‘work-only’ space at home, but I’d only do a 70 mile one-way drive for very special occasions.
The CO2 sensor calibration thing is inherent in the technology. They drift, a lot, and without occasional reference to a known standard, there’s no way to know whether “1000” is really 1000, or 500, or 2000, but exactly how that gets implemented seems to vary a lot. I have an SCD30 board from Adafruit, which internally records CO2 minima and, over the course of week or so, adjusts its calibration so that minimum is 420. That means no special calibration procedure, but it does have to be somewhere that it gets periodic fresh air exposure.
There’s a newer, photoacoustic sensor technology that doesn’t seem to require continuous recalibration, but (at least this one: https://www.sparkfun.com/products/22956 ) require an extensive initial calibration.
