- What electricity costs in my area. $0.32/KWh at the wrong time of day.
I assume you have this on a UPS. What about using a smart plug to switch to UPS during the expensive part of the day, then back to mains to charge when it’s cheaper? I imagine that needs a bigger UPS than one would ordinarily spec, and that cost would probably outweigh the electric bill, but never know.
The politicians made sure to exempt themselves from all the consumer protection, anti-fraud laws. They live in bubbles where their own political agendas are too important for limitations.
But I suspect, because my brand new phone number gets a lot of political spam, that 1) a lot of people can’t live with it and change their numbers to escape or 2) a lot of it is recycled burner-phones, previously used to launder donations to fit legal donation limits. But it’s given me a personal rule to never make a donation from my real phone or allow my real phone to become associated with any political process.
I came to MySQL and Apache because they were the backend for other services I wanted to start,. Later, when I wanted to build my own, I already had Apache running, so why would I add nginx? I did let other services add sqlite, but have (in most cases) figured out how to switch those to MySQL.
All of that has been running for 20 years. I’m sure it would be good for my dementia-risk to learn how to start ngnix and migrate all those services, but it’s far more attractive not to mess with what works.
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.
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.
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
Yeah, my ISP “supports” IPv6, but assigns a /128 to users. It seems to wipe out most of the desirable features of IPv6, and has probably given me a distorted view of its philosophy. OTOH, it did force me to learn how to do DNS views, so names can have the ULA address inside and the global address outside the house, which is pretty cool.
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.”)
Especially if she has 20 years’ experience with CC apps. All of the deeply entrained jargon, keyboard shortcuts, menu structures… Switching apps after that long takes months of training and practice, and the cost of that training is a key lever of enshittification.
With 25 GbE, even 10, I’d be tempted to PXE boot client systems. Maybe still have a local PCIe SSD for windows game files.
Dunno how that would actually work with Windows, but it was fun when I did it for beowulf nodes. Setting RPis to netboot is a little involved, but you can create an OSMC image and give all your TVs a consistent ‘smart’ interface. You don’t even need 10GbE to be pretty functional for the Pi, but my experience is that WiFi is not fast enough.
University is ok if you’re starting at zero and don’t even know what’s out there. It’s for exposing students to a a breadth of topics and some rationale of why things are as they are, but not necessarily for plugging them into a production environment.
Nothing beats having your own real world project, either for motivation or exposure to cutting edge methods. Universities have tried to replicate that with things like ‘problem based learning,’ and they probably hope that students will be inspired by one or two of the classes to start their own out-of-class project, but school and work are fundamentally different ways of learning with fundamentally different goals.
