Many classical email clients have the option to edit the senders address while composing the email. If the mail server does not allow this you usually get an error message on sending.

You are technically correct in saying that it’s not a registration. Instead it’s a sponsoring: https://en.wikipedia.org/wiki/Sponsored_top-level_domain

senders can only be easily forged if you control the senders mail server or if they don’t use best practices for running a mail server.

• DKIM
• DMARC

there are cryptographic signatures on almost all mails sent by large mail providers these days, which makes it very hard to just forge an email that will hold up to closer examination with the help of the provider. so basically the IT techs of the company would need to be on board with whatever the perpetrator is doing, for them to get away with it.

The situation isn’t that different in Germany: emails can be used as evidence in court, though they aren’t as strong as evidence as say: a signed letter. There is also the issue with proving that an email actually arrived, but i would assume that in this case that is already covered.

Actually using AI gibberish for this might be the best strategy of all, since Reddit seems hell bent on making money with AI training and feeding AI generated text into AI training has been shown to yield increasingly worse results over time. So you make the product Reddit is selling less attractive.

So what do you think when you work with HeLas?

centigrade

and he was doing so well until this abomination 😡

Do you mean oldest as in invented the longest time ago or oldest as in that specific technological artefact that i use is the oldest one i have?
For the first one i guess cooking?
For the second one its definitely my microwave oven, made in 1991.

There is a limit on the spacing of the colour bands though. If you want colours then you have to hit the spots where the correct phosphors are and this limits the usable resolution.

So it still uses a MSDOS partition table, interesting. This usually only happens on systems that do not support EFI at all.

Is your BIOS and main board fairly old per chance?

Ok, that looks like a fairly standard setup. I guess taking a look at the boot loader itself would be the next step. When you see the Debian bootloader you could try pressing ‘e’ to view what commands it uses internally to boot. The lines starting with “linux” and “initrd” would be most interesting.

Hi, it would be useful to know what kind of device you are installing on. For a laptop the model and make would be especially useful. If it is a PC then the drive configuration would be interesting (what kind of drive, how many etc.)

Nope, not compression tech. The Einstein refrigerator is an absorption refrigerator and these don’t use compressors.

Most modern operating systems randomize the MAC.

[citation needed]
having the option to randomize the MAC is not the same as actually doing that. There are also a few downsides to random MACs, like captive portals not remembering you on public WiFis.

You mean server? If so, the server is also open source

That is what i meant. It is OSS but not FOSS because you need a key to start it.

Bitwarden has a FOSS client app and FOSS server apps exist (though the default service is not FOSS).

Syncing 2FA keys brings the danger with it that you accidentally sync the key to the device that is used for the first factor thus making it not 2FA anymore.

If they are all installed in the same wine prefix you could back up everything in one go by archiving the “.wine” folder in your home. that will include all applications installed in wine and all settings for those applications.

if you want to separate them into one archive per app you should look into wine prefixes, otherwise you would need to identify every folder a given app created during installation and archive those together manually, which can be very tedious.
