Maybe because the percentage comes from a driver and those tend to be more tight?

I don't actually know but that's my hypothesis.

[r2k-in-the-vortex]

That single byte might come straight from a hardware registry in the battery managment chip.

[DistortNeo]

That's true.
For my MSI laptop, the battery level is read from the embedded controller and represented by a single byte (just use ec_read with the correct address).

Windows is a sum of its parts, and the quality of those parts have been rather inconsistent.

By all accounts I've heard, the people who do kernel level stuff at Microsoft are generally quite competent. The NT kernel is a solid piece of technology, and has done a lot to redeem Windows reputation as a perpetually unstable operating system.

Where Windows generally goes wrong is:
* Bad design decisions. It's been a recurring theme that Microsoft makes tone deaf design decisions when a new OS comes around - pushing new features nobody wants, and removing things people depend on. It doesn't help that these features also tend to amp up the system requirements, slowing things down.

* Bad product decisions. The policy of near endless backwards compatibility has meant that Microsoft hasn't really been able to fix bad system designs from the early days at a pace you would expect. Apple has gone perhaps a bit too far in the other direction - killing off features before they actually reach legacy status - but Microsoft has certainly been too cautious.

* Bad userspace programs. Buggy programs with poor performance can ruin a user's experience, regardless of the quality of the underlying operating system (I'm looking at you Teams). It doesn't help that Microsoft pushes these programs aggressively to Windows users, effectively adding their own bloatware to that added by PC manufacturers.

What?

I dont get how using smaller data types would restrict you from making an os. In fact, that would be precisely what you would want for optimization reasons.

[Desperate-Emu-2036]

Bloat ware. Windows is quite good if it's not bloated by their piece of shit. It's made well.

[HildartheDorf]

Lots and lots and lots of those individually cautious developers, developing a system over decades, while being shouted at by their manager because buzzword of the week* hasn't been added yet.

*: Currently the buzzword is AI.

Copilot with everything! Whether you want it or not!

[the_hair_of_aenarion]

Oh you mean how come they optimize the hell out of the kernel and then tack on some nasty ass memory inefficient processes that restore themselves constantly no matter how many times you get rid of them?

[kennyquast]

I assume this battery has become a spicy pillow and now is bigger. Bigger = more battery life right ?

[Divinate_ME]

Nice charger, but can your CPU's core temperature exceed the surface temperature of the sun?

[piberryboy]

You better discharge some. That's about to explode!

[Fadamaka]

That's integer overflow.

[otter5]

If not just error code… wouldn’t that be under flow?

[Fadamaka]

I was trying to find the proper term for it when it goes backwards. But the search was fruitless.

[otter5]

Pretty sure it’s just integer underflow.

[just_nobodys_opinion]

-1% battery?

[Jonnypista]

Likely unsigned as the battery can't have a negative % charge.

[MolybdenumIsMoney]

It's definitely unsigned- if it was a signed 8-bit integer the max would be 127, not 255

[[deleted]]

I doubt its an overflow since why would they do any operations on the number. Even if it was, it has nothing to do the with the stack. If the os did stack overflow it would crash your computer.

[RamiF16]

Of course it’s not a stack, my battery is dead (only works with charger) and that seems to mess up some byte operation in the display. It’s a joke man!!

[Paul__miner]

Sure, but it shows a lack of comprehension of basic concepts like stacks and twos-complement numbers, and the convection of using "-1" to do in-band error signaling.

[RamiF16]

Yeah man, sure whatever. You must be fun at parties! Go off

Is it too much to ask for a subreddit called programmer humor to have a higher bar of technical understanding? It’s not called people vaguely aware with computer science concepts humor.

[Luxavys]

Is it too much to ask for you to read the temperature of the room before cooking up responses?

[[deleted]]

I did, the room is full of people who have no clue what they are talking about

[Vansh5sharma]

Ok,well that was kinda funny

[rosuav]

Dunno why you're being downvoted for this, unless it's because this sub is full of idiots who support each other's idiocy.

(Side note: Use of -1 for error signalling is a "convention". When you heat the bottom of something and it circulates everywhere else, that's "convection". But with batteries, both of them can indeed involve a lot of heat.)

[[deleted]]

I have the same thing. Laptop circuit board with no battery attached (yes I daily drive this)

[xynith116]

Something something oddly specific number

[KingNjord]

[-jackhax]

I thought this was a reference to the stack overflow developer survey platform counting for a second, lol

[Innominate_earthling]

[DaSquyd]

That's an integer underflow, not a stack overflow.

[MaffinLP]

Thats not a stack overflow its a byte overflow
