Maybe the most impactful, easiest, and most expensive thing is to get your information off of the internet. There are a few services that do this like incogni but I'd recommend kanary. The gist is they have a list of known data brokers and they send out requests to them, on your behalf, to remove your information from their services.

carzian ,

You've gotten a lot of good answers, so I'm going to do some out of the box thinking - maybe it will spark a few ideas.

Goal:

  • self hosted server on boat

Issues:

  • size
  • power
  • corrosion

So if I were going to do this myself, I'd start with a pelican or other similar watertight container. We don't want the equipment getting wet, and we don't want it exposed to the salty air.

I'd probably pick a usff computer, like a dell 9020 or maybe a framework motherboard. To get the storage, I'd get one of these to add multiple sata ports to the computer. Then its a matter of getting a bunch of ssds and powering them. I think the 12v goal is going to be too restrictive, most laptops need 19v to charge, so I'd just bite the bullet and get an inverter. If you're really tight on power you could go with a pi, but the framework motherboard/usff both use mobile processors, and shouldn't draw too much while idle.

Any wires that pass though to the case should be made through waterproof bulkheads.

Personally I'd nix the HDMI out requirement. One more port to keep track of and it complicates the self hosting. If you want it for media streaming to a TV then I'd recommend a roku and just run a jellyfin server on the computer. If you want it for server debugging I wouldn't bother running it out of the case.

The last thing I'd do is figure out cooling. For this I'd probably create some sort of closed loop heat exchanger from the case to either the outside air or the lake/ocean itself. This could be as simple as a pump running water through two radiators, one in the case and the other outside or just dumped overboard. If you know your power usage ahead of time you might be able to get away with a peltier element, dumping the heat outside the case.

I'd probably put this all on its own power system, get a solar panel, battery, inverter, etc. It could even get topped off by the boat's system if it needs extra juice.

Also whatever you do, I'd figure out a way to ensure you're giving your system a clean and steady 12v.

I've always liked the ultrastar line. Used to be made by HGST and then WD bought them. I'm using specifically the HC530 14tb. The line has a long history of being very reliable enterprise drives.

I've bought mine from both goharddrive and serverpartsdeals. Both are reliable resellers of used storage. They'll warranty the drives for 2 or 5 years depending on which you to with. Prices are ~$130-$150.

Be aware you might need to do the electrical tape over some of the power pins hacks depending on your setup.

Ps. One of the listings for the HC530 on goharddrive or serverpartdeals is incorrectly labels as HC520. Just pay close attention.

As far as raid goes, Raid 10 is currently very popular for its speed and drive failure tolerance. Remember, raid is not a replacement for the 3-2-1 backup rule. Raid has some fault tolerances for bad hard drives, but doesn't protect against a failed raid card, fire, flood, robber, acts of god, etc.

You can also look into zfs and truenas if you feel inclined. Be aware that if you go with this setup, ecc ram is basically a requirement

"The cause is a new SATA specification which includes the ability to disable power to the hard disk. When you look at the SATA power connection on the back of your hard drive, there are 15 pins that make contact with your power supply. It's the third pin that delivers a 3.3V signal that disables the drive. What we need to do is prevent that third pin from making contact with the power cable."

Some hotswap harddrive bays use this feature, definitely more common in enterprise scenarios or in USB HDD enclosures.

I've used incogni and kanary. I'm not a fan of incogni. They have a list of data sellers and blast each one with requests to remove your data, whether or not they actually have it. Additionally I've been asked many times to verify information they found to see if its mine. Its not, like not even close. Same last name but the first name, age, and location are way off.

Kanary's been much better about targeting my specific information for removal. Its more expensive but I think they do a better job overall. I'm definitely more confident in them than incogni.

The Best Email Aliasing Providers in 2024 (blog.thenewoil.org)

Email aliasing is one of the most underrated privacy techniques that has yet to go mainstream. For the privacy-conscious user, it offers a degree of separation between all your accounts, making it harder for data brokers to correlate your various accounts across different services by not using the same email address to sign up....

carzian ,

I've been using Addy for years and it's been great. I believe I'm on the lite plan and have never (to my knowledge) hit any limits. Definitely recommend.

Data storage vs backup storage

@memes

Oh it hurts real bad

Can someone explain the "don't put all your eggs in one basket" argument to me? (kbin.run)

I'm (probably) switching to Proton Pass from Bitwarden because its easier to create email aliases (all in one instead of making an alias with SimpleLogin, then copying that to Bitwarden and making a password there) but I've heard people saying not to use Proton Pass to not "put all your eggs in one basket". Can someone explain...

carzian , (edited )

A (small) part of not putting all your eggs in one basket is also avoiding vender lock-in. Having your personal email with proton, and your password manager with them makes it very difficult to switch in the future if you need to.

On a side note, I use anonaddy (now Addy.io). It allows you to create email aliases on the fly. So when I sign up for a new account somewhere, I generally make up some email like "example@my-account.anonaddy.com" for the email and save that right to bitwarden.

Looks like simplelogin supports the same thing

PS. Using your own domain name is a great way to avoid vender lock-in =)

carzian ,

Migadu micro tier is $19/year. Great service and has a great privacy policy. Basically unlimited domains. Ive been very happy with them.

carzian ,

You need to research raid 1,6,10 and zfs first. Make an informed decision and go from there. You're basing the number of drives off of (uninformed) assumptions and that's going to drive all of your decisions the wrong way. Start with figuring out your target storage amount and how many drive failures you can tolerate.

carzian ,

That's definitely something to be aware of, but the vdev expansion feature was mergered and will be released probably this year.

Additionally, it looks like the authors main gripe is the current way to expand is to add more vdevs. If you plan this out ahead of time then adding more vdevs incrementally isn't an issue, you just need to buy enough drives for a vdev. In homelab use this might an issue, but if OP is planning on a 40 drive setup then needing to buy drives in groups of 2-3 instead of individually shouldn't be a huge deal.

Email service that integrates well with Thunderbird?

I hope I'm not annoying you kind folks too much with my ongoing Tutamail woes, but, in the long slow process of divorcing myself from them (and returning to Thunderbird), I'm looking for an email host/provider that integrates well with TB, meaning that it can sync mail, contacts, calendars, and tasks between the Linux desktop...

carzian ,

I've been using migadu and its been great so far

carzian ,

So you're planning to reuse the same hardware that the firewall is running on now, by installing a hypervisor and then only running opnsense in that?

carzian ,

Ah ok. I've done opnsense and pfsense both virtualized in proxmox and on bare metal. I've done the setup both at two work places now and at home. I vastly prefer bare metal. Managing it in a VM is a pain. The nic pass through is fine, but it complicates configuration and troubleshooting. If you're not getting the speeds you want then there's now two systems to troubleshoot instead of one. Additionally, now you need to worry about keeping your hypervisor up and running in addition to the firewall. This makes updates and other maintance more difficult. Hypervisors do provide snapshots, but opnsense is easy enough to back up that it's not really a compelling argument.

My two cents is get the right equipment for the firewall and run bare metal. Having more CPU is great if you want to do intrusion detection, DNS filtering, vpns, etc. on the firewall. Don't feel like you need to hypervisor everything

carzian ,

Did you expose your router login page to the open internet? How'd they get access? Why are you chmoding anything to be 777?

carzian ,

Can I talk to you about our Lord and Savior Tumbleweed?

carzian ,

Admittedly, I haven't done too much of that, but it might still be more stable than needing to reinstall your OS every 2-3 weeks?

carzian ,

Give it a shot, you can always go back

carzian ,

What are you running home assistant on?
On my pixel the app only takes ~2 seconds to open and load on 4G

carzian ,

I meant the host computer, raspberry pi?
I was giving my phone opening time as reference, should have made that more clear.

I'm also on a pixel fold. The performance is fine for me, but I'm hosting home assistant on a VM running on a server with Ethernet to my networking switch.

carzian ,

Same experience here

carzian ,

Pill cutters are situationally easier for the elderly to use. They're portable, don't require a cutting surface, and generally have guards along the blade making it safer than a knife.

What works for me is snapping it while my fingernail is in the groove. Gives a clean break down the center like every time.

carzian ,

Theres no such thing as "real stainless". Stainless steel 304 is corrosion resistant, it's the cheapest and most common. 316 is better at corrosion resistance and is "marine grade" since it will hold up better to salt water. 316L is some of the best at resisting corrosion, it's more expensive than 304 and is used in lab and surgical equipment. There are a lot of other types, like 309 for higher heat applications, etc.

Cybertruck is probably made from 304.

Definately not supprised that cybertrucks are having this issue. Especially with road salt in the winter. I'm sure the engineers at Tesla saw this coming too.

The models are getting imposible to repair. Everything is plastic and isn't designed to be taken apart. It's lenovos fault, their build quality is crap across the line. Of all the computers I've fixed (which is a lot), lenovos are by far the worst to deal with

carzian ,

I'm not unfortunately. I had to fix a coworkers thinkpad t14 gen 3. The motherboard failed. Then the replacement was throwing fan errors for no reason, finally went away when I updated the bios. Now its going back to lenovo because there are graphics artifacts on the screen during normal use.
It being made out of slightly better plastic doesn't mean anything, they cheaped out on everything.

carzian ,

I don't think I've been in those subreddits unfortunately. I guess Lenovo fired all their good engineers? My father has a Lenovo all-in-one. I actually cracked the screen trying to open it to upgrade the ram. To get to the motherboard you need to remove the front bezel, but the screen is just a thin panel that juts right to the edge with 1 or 2mm of space to spare. It's a crapshoot whether or not you can undo all the plastic snaps without accidently grabbing the screen. It really is affecting every computer in their lineup

carzian ,

The Dells I've come across are all infinately easier to work on, and have had fewer problems. I hope you have a better experience than me, but I can't recommend anything from Lenovo

carzian ,

You're comparing a microcontroller to a purpose built device. Its apples and oranges.

There are add ons to the flipper that incoporate an esp running maurader firmware for wifi tools

He only said wish once and had everything in one sentence. Would that only count as one wish?

If no, what if he said "I wish I owned a shipping container, and all of its contence, which include a pile of money, a jetpack, and blah blah". Where's the line?

carzian ,

Have you considered using
https://github.com/imranr98/obtainium
You give it the repository of the app and it will handle checking for new versions and updating them
