There’s two things you might be talking about here:

The old way of making sure nickel cadmium batteries didn’t degrade, which was to discharge them all the way and charge them back up all the way. Your new laptop is almost certainly using lithium ion batteries which are chemically “damaged” more through that process than just leaving them plugged up all the time.

You could be talking about the old way of dealing with charge controllers, where the controller relied on the bios or os to tell it what to do and didn’t “know” how to respond to batteries at different stages of charge. This hasn’t been the situation for like fifteen years. Nowadays charge controllers go “yup, ready to go boss, 12345mah of charge, 90%” when some bios or os polls them.

You don’t even need to manually keep your battery in the 20-80 range nowadays since almost every charge controller automatically monitors temperature and adjusts charging parameters to not damage the battery. It’s not like the old days where the charge controller was just an ic controlling a fet acting as a slucegate between the battery and the power brick.

Heck, lithium ion batteries nowadays last longest the longer they’re plugged in. Running them to <10% every charge cycle actually diminishes battery life!

Tldr welcome to the future, don’t worry about it!

Bash is fine. Zsh on Macs is fine too. I can’t stress how useful it is to learn busybox if you end up with a shell on an embedded device.

All these crazy shells people talk about are kinda like race car controls. I’m not driving a race car, I’m driving a box truck with three on the tree.

Theres a lot to break down here, but that seems like bullshit.

I only post negative comments about Biden. Am I gonna get banned for never saying anything nice about the president?

Omg this is so true! 💅🏻

Death to America, Death to Israel.

People are saying it more and more!

that's nice, but the whole reason recapcha and other ai training capchas exist is that it costs money to host and maintain those services and they're able to recoup those costs by harvesting and monetizing user data.

capchas literally do have to be boring dystopian bullshit because no one will pay for the alternative.

Yeah, there’s nothing political about free software! Why should we have to read about people’s liberatory ideas in the linux community?

It’s absurd I tell you!

[-] bloodfart@lemmy.ml 17 points 7 months ago

Don’t look into that recycling either. It’s just arbitrage all the way to the acid vat man.

Morning,

Os upgrades are free since like 2012. There’s a bunch of software that comes with the os that’s free and a boatload of software in the App Store that’s free.

If you make an apple id you can use stuff that needs it like messages, icloud etc. without an apple id those programs are on your computer but they don’t work fully. An apple id is required to use the App Store I think, so I guess that’s an example of software you need an apple id to get.

There’s both buy once, cry once versions of office and saas versions. I think adobe is fully saas now.

Libre office works fine on a mac.

You don’t need to use an emulator because there are systems like homebrew to let you natively run lots of free software on a mac. If you do want to run a vm, there are paid and free options.

Did you ever get that mbp 11,1 upgraded?

The device is vulnerable. The webcam is one way that gets exploited.

If it makes you feel safer, cover the camera when you’re not using it. I can’t comprehend why a person wouldn’t cover it up when it’s not in use. It takes one second.

Stay patched up.

You’re not making a very good case. Historically speaking, American gun laws have universally been about disarmament as opposed to harm reduction.

If, for example, the awb had included free publicly accessible classes on gun safety and massive funding for mental health services then you’d be able to make the connection between gun control laws and an effort to lower child mortality.

So when your rowboat is floating, it can displace a certain volume of water and if it displaces more than that volume the water spills over the sides and it sinks. We talk about how many tons of water it’s displacing because that tells us what the total weight of the boat, you, cooler, beers, tackle and oars can be before the boat sinks.

You already knew that though. What might not be clear is what that weight measurement actually is.

Weight is the acceleration due to gravity that an object experiences. So if your rowboat is able to displace a volume of water that experiences more acceleration due to gravity than it and all it’s contents do, it will stay on top of the water in a state we call floating even though it and some of the contents may be more dense than water!

Now your rowboat is different than the balls in that floating glass ball thermometer your aunt bought out of sharper image in one very unique way: it can’t function when submerged! Those little suckers will go up and down all day, but once water starts coming in over your gunwales you gotta get rid of it or the boat sinks and won’t come up.

So there’s a point of no return where your boat can’t stay afloat any more.

When it displaces a volume of water that experiences less acceleration due to gravity than it and all its contents do, it and all its contents are pulled under the surface of the water. At that point, density determines what happens to the boat and it’s cargo. The boat itself may be denser than an equivalent volume of water and sink, but the beers and cooler are less dense than water and they float. You may be more dense than water, but instead of sinking you tread water and push your head up above the surface.

When the swamped boat sinks, it experiences more acceleration due to gravity than the water around it and pushes that water aside on its way to the bottom of the lake. The beers experience less acceleration due to gravity than the water around them so the water is pulled underneath them and they float. The air pocket inside each can also lends some displacement to the cause.

So the volume of fluid displaced isn’t “slight”. It’s exactly what gravity itself requires for objects to sink or float!
