I would look into something like Doppler instead of Vault. (I don’t trust any company acquired by IBM. They have been aquiring and enshittifying companies before there was even a name for it.)

Look into how any different solutions need their keys presented. Dumping the creds in ENV is generally fine since the keys will need to be stored and used somehow. You might need a dedicated user account to manage keys in its home folder.

This is actually a host security problem, not generally a key storage problem per se. Regardless of how you have a vault setup, my approach here is to create a single host that acts as a gateway for the rest of the credentials. (This applies to if keys are stored in “the cloud” or in a local database somewhere.)

Since you are going to using a Pi, you should focus on that being a restricted host: Only run your chosen vault solution on it. Period. Secure and patch it to the best of your ability and use very specific host firewall rules for minimum connectivity. Ie: Have one user for ssh in and limit another user account to managing vault, preferably without needing any kind of elevated access. This is actually a perfect use case for SELinux since you can put in some decent restrictions on the host for a single app (and it’s supporting apps…)

If you are paranoid enough to run a HIDS, you can turn on all the events for any type of root account actions. In theory once the host is configured, you shouldn’t need root again until you start performing patches.

That’s what you just got shown: Shove the configgy bits into Git.

You will likely have to find the configs you want to save first.

Solar panels are more efficient closer to the equator because of the most direct light from the sun. At higher or lower latitudes, there is more atmosphere for the light to pass through. The actual distance from the sun is basically irrelevant without an atmosphere. There might be a measurable difference based on distance alone but not much.

Efficiency does not generally equate to optimal power generation. There are probably hundreds of other variables that directly translate to maximum power production.

When? That shit is already happening.

Acktually, this is a decent last resort if you have an alkaline battery leak all over a PCB. Hot water is probably not a good idea as you run the risk of warping a board.

A tooth brush and an isopropyl bath is probably a better option unless you have a good ultrasonic cleaner.

An isopropyl bath after a water bath is also good as to remove all the water from places you can’t dry easily. (Evaporation of the IPA is hella better than using a hair dryer because again, warping.)

Unfortunately, AI has the creativity of a turnip.

“Political headwinds” is putting it mildly.

And the really rich kids get to use ostrich eggs.

Psychedelics can absolutely kick that set-point into another universe if you let them. I can’t begin to explain how it works or how it feels, but I have personally have had some very significant life changes since I started using them on a regular basis.

Sure, you can use psychedelics for fun, but in a proper environment they can be a strong driver for extremely healthy mental change.

Real work is an absolute requirement. No argument there. However, a person may need a complete mental rewiring to get to the point where they are willing to move forward. Like myself.

Use local accounts only and do not login to a Microsoft account.

Edit: In my situation, I used an MS account during a reinstall and disabled backups and logged out quickly after. There are methods to still do an offline install, from what I understand.

Disabling backup is annoying, but not hard.
