It would be nice if you could post something where we can examine the source. (EDIT: the link has been changed since I wrote this)

I found this article: techspot.com/news/108720-hidde…

There they say that it's not yet ready to be used in evidence, but the problem with that is that most forensic "science" is generally misapplied and nowhere near as conclusive as the police want us to think. They can usually massage the results to tell a jury what they want to be true. That would be my concern with this kind of technique.

Also, if you're going to the trouble of making a 3d printed ghost gun that will be used in a crime, you could always hide the toolmarks with a sander. You could also treat the surface with resin which would make the markings practically unrecoverable. I've started doing both of these for my prints and I love the results just for the aesthetics, so it's not such a stretch to imagine a gunsmith doing the same.

The hidden fingerprints inside 3D-printed ghost guns

Kirk Garrison, a forensics expert who works for the San Bernardino Sheriff’s department, told 404 Media he’s had early success matching 3D printed objects to the machines that made them.

This is "bite evidence" all over again, isn't it? For those not familiar, cops swore in court they could match a perp's teeth to bite marks on victim's bodies.

They couldn't.

There were a lot of tainted court cases because of their junk science. I'm all for murderers going to prison but lets not use bullshit to lock up perhaps the wrong people.

Just based on the title, since I haven't read the article yet, that's quite unfortunate. I would want all of them to be practically identical, so there's no way to trace them at all.

Edit: After reading the article, I stand by my above statement. I still want them to be completely identical if at all possible.

Some good discussion from /c/3dprinting@lemmy.world about how it really isn’t as dependable/tracable as the article says:

lemmy.world/post/33199760

TLDR is 3D printing typically uses brass nozzles which wear down over time which will change marks left over time, your bed leveling can change over time, and the “fingerprints” the article talks about can be avoided by just printing in different positions/rotations on the bed.

Password manager such as Bitwarden, you can store your passwords, and sensitive info as notes or attachments. It's all encrypted client side.

Then you just need to have a note with the master password and instructions on how to access it.

every time I update a password

Use a password manager. KeePassXC stores stuff in a file, so it's easier to synchronize. You can selfhost BitWarden too.

Syncthing is great to synchronize stuff across devices.

Cryptomator creates encrypted volumes (looks like a folder with gibberish inside) for you, which you can sync with whatever commercial cloud.

Putting a document on a flash drive

Data loss might come from bitrot, yes. Regardless, you should always have multiple backups.

Self-host Bitwarden | Bitwarden

Customers wishing to self-host a Bitwarden server for their organization or personal use have a variety of deployment options, including options for the server and infrastructure Bitwarden is deployed on, the database used by the server, and the cert…

^Bitwarden

This is the one reason I’ve paid for 1Password. My wife has access and can get what is needed without figuring out how to revive a self hosted password solution. I realize this isn’t about self hosting, and that you can pay for Bitwarden too. It just struck a chord.

OP wishing you all the best.

Why not just put logins in a database such as keepass and then have the password for that written down in like a lock box or something?

You could also store a flash drive with the password in the lock box and update it, say, every six months with the most current database version.

No solution I've found, but I've been working on this myself. As I see it, there are two situations, and four categories of data:

I. My wife survives me
II. We both die, e.g. in a car

• Digital media
• Financial accounts
• Subscriptions
• Physical possessions

I've been thinking about getting an M-Disk writer for media, because ultimately, backing up to B2 is fine until I'm gone. Family members will need physical media for the photos and stuff.

For secrets, I'm planning using SSSS. Keys will be given to members on each side of my wife's and my families. If we both die, they'll have to get together, put their keys together, and decrypt the KeePass DB.

The online accounts are almost all financial; those are in a KeePass DB. My wife already has access to all of that through power is attorney, and if we both go, it's SSSS for the family.

The third data category are accounts and services that will be to be stopped. I don't subscribe to much, but the VPS provider and B2 will have to be terminated, and a document with instructions and with the credentials is in the SSSS archive.

The final category are assets: home, mortgage info, where and what the M-Disks are, a copy of the will that deals with all of the valuables, and any notes about anything not covered in the will. That's in documents in the SSSS archive.

I still have to put the archive together. I've been working toward a state where all of the secrets are in a cryptfs that's shared on the LAN and automatically encrypted with SSSS and synced to a share. Once I have that automated, I'll communicate out the SSSS keys and a how-to document.

In some ways, it was easier when you just died and your kids fought over the china. But I have a plan.

My mother died recently, and she was the breadwinner and was in charge of everything financial, because my surviving father is a toxic narcissist with zero financial literacy who refuses help from anyone. So I just have to say kudos to you for thinking about this difficult stuff. Your family will appreciate it more than you can imagine.

Other commenters have already given you solid advice, and I don’t have anything to add there, but more people need to have these difficult conversations and make real practical preparations, as soon as possible. Speaking from experience, not having clear guidance about where things are and what should be done with them, makes an already emotional situation even harder to deal with. Everybody dies, but in death you can make your family’s grieving process slightly easier by thinking ahead like this.

I’m sorry for whatever you’re going through, but props for thinking about other people while you go through it.

"In this envelope is the password for my keepass password vault. The entry for "In case of emergency" contains everything you should need to know in the event of my incapacitation or worse.

There are two USB keys with this vault on them, they are synchronized for redundancy. When I pass, get the password out of this envelope, plug in a USB key, open keypass and enter the password. "

You: Use the primary key as your password storage, keep the backup key plugged into a raspberry pi, run syncthing on both devices.

Have a spare test key set up, do a dry run with the family members you entrust to have this data.

You kinda only need the email credentials. Shouldn't the rest be resettable from that point?

Is there anything that needs MFA that they won't have?

I do not believe that LLMs will ever be able to replace humans in tasks designed for humans. The reason is that human tasks require tacit knowledge (=job experience) and that stuff is not written down in training material.

However, we will start to have tasks for LLMs pretty soon. It was already observed that LLMs work better on stuff produced by other LLMs.

Compounding tasks like accounting where operations sound easy but create a chain of counter entries and balances need to be organized by account is none of AIs business until they can prove that multiple sequential steps can have over 99% accuracy and the checksum of the accounts is balanced.

Multiple sequential steps with six operations where we assume 99 PCT of each, is right can equal 90% accuracy.
This also reads at least 10% errors if they all six go wrong.

How many different entries are in a company over a month's closure?

Now this wouldn't be and issue if it can balance the statements of consolidated accounts and find where are we missing entries or misallocations. That sir is why we pay someone with experience.
