If a minimum wage worker started working at age 18, and worked until 67 (the retirement age set by the US Social Security Administration) and worked 40 hours a week every week, they would make less than a million dollars in their life (at the US federal minimum wage of $7.25 per hour).

So, a millionaire with $10M would have to spend more than 10 lifetimes making up the overpayment.

A billionaire with $1B would have to spend more than 1000 lifetimes.

A billionaire with $200B would have to spend 269,745 lifetimes.

Anyone got a good lead on a Replicant-capable phone? I'm currently running LineageOS on my phone, which is alright. But, of course, it has a bunch of proprietary firmware and I think proprietary drivers in it. I have a tablet that runs Replicant, and I love it, because it's 100% free open source software. I chose not to add any proprietary firmware to my Replicant tablet's image, so it doesn't handle video that well, but it's good enough for what I need.

I'd love to get a new phone that could be as FOSS as possible. Either Replicant, or maybe a modified LineageOS, or perhaps something else if anyone has any good ideas!

I have only a bit of experience with Android at the low level, but I know a little bit about adb and unlocking bootloaders and stuff.

My headcanon is that Number One is the in-universe voice actor for ship computers in Starfleet. Once they made the computer model of her voice, it remained in use all the way to the TNG era.

I doubt Lwaxana Troi would have been interested in sitting still for a hundred hours of voice recording.

I believe it is:

spoilere^W(W(ln(2))

spoiler

x=W(x)*e^(W(x))

x^(x*x^x)=2
x*x^x*ln(x)=ln(2)
x*e^(ln(x)*x)*ln(x)=ln(2)
u=x*ln(x)
u*e^u=ln(2)
u=W(ln(2))
x*ln(x)=W(ln(2))
e^(ln(x)*x)=e^W(ln(2))
x^x=e^W(ln(2))
x = square-super-root(e^W(ln(2)))
wikipedia says this is equivalent to:
x=e^W(ln(e^W(ln(2))))
but I don't know how they arrive at that.
x=e^W(W(ln(2))

working backwards to verify:
x=e^W(W(ln(2))
ln(x)=W(W(ln(2))
ln(x)*x=W(ln(2))
ln(x)*x*e^(ln(x)*x)=ln(2)
ln(x)*x*x^x=ln(2)
e^(ln(x)*x*x^x)=2
x^(x*x^x)=2

The text of this post appears wrong on old.lemmy.world. It says "Solve x for x^x*x^x^ = 2" with no superscripts. It appears correctly on lemmy.world.

I assume we're meant to find an expression of W() and square roots and stuff, which expresses an exact answer. Since finding a decimal approximation somewhere between 1 and 2 using a binary search would be too easy.

Actually, I think that's a really good idea. Just be aware of possible inductance in the long wires from the transformer area going to the camera. Putting a large electrolytic capacitor next to the camera should fix that.

As for your bell, there are dead simple systems that use a battery-powered stick-on button with a transmitter, and a chime/receiver that plugs into a wall. If you want to be fancy, you could find a way to power the transmitter with that 5VDC, in parallel with the camera... or you could just keep it simple and use the battery that comes with the button. They last near forever.

Remember that voltage is measured across a pair of wires, so you can't power the chime with only a single wire. That's part of what makes this difficult -- these doorbell systems only have the bare minimum of wiring in them. Powering the camera and the chime in series with each other is quite difficult. I think a lot of these things just accept the short circuit, and use a battery to power the camera while the button is being held.

Here is what I was proposing, and I think what ch00f was also proposing. Replace "5VDC power supply" in this diagram with "a full bridge rectifier and a bunch of caps" in their description, and also note that your camera probably requires a well regulated 5VDC supply.

[–] Limonene 2 points 10 months ago (1 children)

The easy way: take your existing wiring. Put an 18VAC to 5VDC power supply in parallel with the pushbutton. Then, the output of that power supply goes to the 5V USB input of your camera setup.

The downside is that it will reboot the camera every time someone rings the doorbell, because you are shorting across the camera's power supply.

You can put a resistor in series with the button to fix this. You will need to find a resistance that's low enough to still cause the chime to ring, but high enough not to disrupt the camera's power supply. Maybe start around 20 ohms. If you can't find a working resistor value, you can change the transformer to a 24V or 36V transformer, but make sure to keep that resistor high enough not to burn out the chime, and make sure your 5VDC power supply can handle the increase in input voltage.

This is false. X is not less secure than Wayland. It does have a different security model, which can become insecure if you misuse it. I don't think people really care about situations where multiple user accounts access the same display.

In my opinion, the benefits of xdotool far outweigh any benefits gained by Wayland's security model. It's impossible to make xdotool in Wayland, because of its security model.

The war in Gaza isn't the only thing going on in the world, you know. It's not even the deadliest war going on right now. Take a look at the list: https://en.wikipedia.org/wiki/List_of_anthropogenic_disasters_by_death_toll#Wars_and_armed_conflicts

The current era of the Israel-Palestine war (since October) has a death toll of around 30k. Look at how many other current and recent wars have death tolls of at least that much. Notably, the US-Afghanistan war (around 193k deaths) was ended by Biden.
