(For others reading this, this is a perfect followup to my comment here explaining the “why”, while this is an excellent view into the “how” and picks up the bits I dropped about Ohms Law.)

Pin pitch is pin size and/or spacing. With physical plugs, you start to hit limitations with how small the wires can get while still being durable enough to withstand plugging/unplugging hundreds of times.

Drop losses. (I am keeping this at an ELI5 [more like ELI15, TBH] level and ignore some important stuff) Every electronic component generates heat from the power it uses. More power used usually means more heat. Heat requires physical space and lots of material to dissipate correctly. Depending on the materials used to “sink” (move; direct; channel) heat, you may need a significant amount of material to dissipate the heat correctly. So, you can use more efficient materials to reduce the amount of power that is converted to heat or improve how heat is transferred away from the component. (If you are starting to sense that there is a heat/power feedback loop here, it’s because there can be.) Since a bit of power is converted to heat, you can increase the power to your device to compensate but this, in turn, generates more heat that must be dissipated.

In short, if your device runs on 9v and draws a ton of power, you need to calculate how much of that power is going to be wasted as heat. You can Google Ohms Law if you would like, but you can usually measure a “voltage drop” across any component. A resistor, which resists electrical current, will “drop” voltage in a circuit because some of the current (measured in amperage) is converted to heat.

I kinda smashed a few things together related to efficiency and thermodynamics in a couple of paragraphs, but I think I coved the basics. (I cropped a ton of stuff about ohms law and why that is important, as well as how/where heat is important enough to worry about. Long story short: heat bad)

That comment is pure gold and I am archiving it for future use.

I looked into that and the only question I really have is how geographically distributed the samples were. Other than that, It was an oversampled study, so <50% of the people were the control, of sorts. I don’t fully understand how the sampling worked, but there is a substantial chart at the bottom of the study that shows the full distribution of responses. Even with under 1000 people, it seems legit.

In this study, we conducted a survey (n = 742) including a representative U.S. sample and an oversample of gender minorities, racial minorities, and disabled individuals to examine how demographic factors shape AI attitudes.

Lol, no. Most of maga can’t even spell Europe, so all of those things you list, while true, are way beyond their comprehension.

The politicians just point at European countries and say they stupid because they talk funny and they are stealing from you. (It doesn’t matter if that is true or not, it’s just “someone else to blame” for made up problems.)

Just to go a bit deeper, everything should be considered a resistor, capacitor and inductor.

But in the UK, is a crisp “crispy” or is “crisp” a derivative of another term or phrase?

I mean, sure. You do you, friend.

It’s a sideways chefs kiss. Also, something, something, penis size.

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.
