I dual boot SteamOS and Windows 10 IoT LTSC mostly because there are still some game developers that can’t figure out how to enable anti-cheat for Linux.
And does Windows rewrite my boot sequence every time?
Sure, but it’s a sacrifice I’m willing to make.
I absolutely believe this

Fuck you for not welcoming a new user.
OP you are welcome on Lemmy and the wide Fediverse!
Many inverters aren’t even UL listed.
Yes but many inspectors and insurance companies won’t want you to install electrical equipment on “real property” or buildings if it isn’t UL as that falls into the scope of AHJs and insurance providers. If there’s something that has the potential to start a fire, you need to have safety certifications so operating the system not only reduces the risk of fire, but also selling the house in the future to a new owner doesn’t come with excess burden on behalf of the next insurer.
If your solar system is off-grid AND off-building, I see no reason that you need to have a UL listed system.
This is of course dependent on local AHJs and utilities, but UL 1741 covers both standalone (off-grid) and grid-interactive (on-grid) inverters. If you’re choosing an inverter manufacturer that makes non-UL listed off-grid inverters, I would probably be suspect of their products’ quality as it’s easier to gain UL listing regardless of how the inverter is used: off-grid or grid-interactive.
That’s the problem.
That is a problem. Off-grid inverters that aren’t certified to UL 1741-SB aren’t required to have anti-islanding protection that cuts the inverters off if there’s an absence of grid voltage. If a “balcony solar” inverter were to NOT cease to energize upon loss of grid and stay islanded, then voltage is introduced to the building’s/community’s shared local distribution system. If work were to be done on that portion of the distribution system or grid where lineman and wireman expect conductors to be de-energized, then you might have injuries as a result. Now, you may be able to say that lineman and wireman should always test for presence of voltage prior to doing work, and as a solar engineer I would absolutely expect folks to do this, but that’s not always the case. People cut corners. And in the event that certain crews cut corners, don’t check for voltage and investigate where the voltage source is, and start touching wires and introducing paths to ground, people can get seriously injured or die.
You may think that because solar panels are current-limited that this fact protects workers in the event of becoming exposed to live voltage, but any combination of voltage and current can kill.
I’ve always wanted DRM for my inverter.
In the context of safety, this is a good thing. Skirting DRM on movies or TVs won’t mean you injure yourself or others or worse. Skirting inverter settings can cause inverters to operate in ways that are unintended, and could hurt people. These things are not the same, and it’s concerning that you can’t see the difference.
Also, having locks on settings means that other bad actors are deterred from changing those settings maliciously, whether intentional or not.
There is not substitute for a qualified person operating and maintaining an electrical system, regardless of voltage.
I think it should just require a permit
Agreed
Inverters in the US are all listed to UL1741-SB which dictates that they shall cease to energize their AC outputs if they sense an absence of grid voltage.
Now, one thing people are ignoring is that UL1741-SB allows for islanding protection, and the disablement of it. If an inverter has its settings changed such that islanding protection is OFF, then the inverter will keep sending power to the “grid” because it thinks it’s operating on a microgrid that was previously disconnected from the larger grid via a Microgrid Interconnection Device (MID).
The settings these inverters have are user-settable, which means they need to be checked by a qualified person, either a contractor, engineer, or inspector. These settings must also often be checked by the utility you’re interconnecting to before they allow you to energize, so usually all of these parties have eyes on the inverters’ settings and can stop work before energization until things are corrected.
Ultimately I agree with you. If we don’t want to have to need inspections for every solar installation, especially residential ones and especially where plug-and-play solar modules are used, then inverters need to have their settings pre-configured for the grid code in the factory that then cannot be changed by the user or operator in the field. That would be a way to shoe-in this kind of installation.
Hard setting grid codes into inverters prior to shipping to site might be overly conservative though, especially as utilities change their grid codes over time. You need to have a way to update those settings, which could be using a wireless portal hosted by the inverter OEM with credentials made only available to the OEM. Problem with this is that then you shift the burden of configuration to the manufacturer which already has a ton of other UL standards as well as rules and regulations to follow.
What do y’all think?
Thanks for this explanation. This was my understanding as well, except for the GNU part.
I asked because the parent commenter directly above my first comment made the distinction between the operating system and the kernel. I wasn’t actually sure what the overall umbrella “OS” was for Linux, since as you say the kernel is Linux while there are GNU packages. I can’t really recall someone on Lemmy saying what exactly the operating system is for any given computer that happens to run Linux as the kernel.
I guess this scratches at what the definition of an operating system is: Windows, macOS, or GNU/Linux. In reality, doesn’t Windows run on the Unix kernel? Why don’t we call it Windows/Unix then? Is Unix used with other “operating systems” that layer on top of the Unix kernel itself?
I went to school for electrical engineering btw and had to take many classes about digital logic and all of the entry level stuff about PCs at a hardware level. Didn’t really get taught much about what goes on top of the hardware aside from maybe microcontrollers with Assembly and C.
Thanks anyways!
The real title is always in the comments
As a Linux n00b, now I need to know which is the kernel and which is the OS.
I believe Netflix does yeah. Foreign language shows don’t bother me
I enjoyed this one. Crazy that it’s only 1 season tho
12 Monkeys and DARK. Both shows deal with time travel in a very cool way.
Severance and The Boys are also fantastic.
Coyotes are also present in many places in the US, and birds of prey can harm pets too.
No excuse for eliminating a healthy and necessary species from the ecology. Human ego trumps all
Ban lead bullets then. Allows people to keep hunting while preventing more pollution in the wild.
Plenty of time after that to ban other things.
ecologically necessary
Not if wolves were reintroduced to native levels.
Can Cloudflare help prevent this?
Kubuntu users rise up!
Oh when will China start making HDDs and SSDs and GPUs and CPUs
PLEASE China PLEASE flood the market with cheap, top shelf computer parts that will force Western corporations to lower their prices or go bankrupt when they don’t
The obvious solution is architecting society such that parents have more time to parent while making enough to pay the bills, rather than exporting parenting because they can’t afford to miss work due to parenting.
You start having enough of these conversations, and it all eventually points back to capitalism and taxing the rich.
I drive Windows mostly on my Deck but only because Marathon doesn’t run on Proton (yet).
Otherwise I always ran SteamOS for Chivalry 2.
