Yeah, that’s probably a fair answer for some folks and systems. Depends on what your system is doing, your risk tolerance, and what money you’re willing to put into the thing.
If I didn’t have a backup system in place, say, that’d be much higher on my list than trying to ensure power isn’t cut off unexpectedly during power outages.
I agree that it’s less-critical than it was at one point. Any modern filesystem, including ext4 and btrfs, isn’t at risk of filesystem-level corruption, and a DBMS like PostgreSQL or MySQL should handle it at an application level. That being said, there is still other software out there that may take issue with being interrupted. Doing an apt upgrade is not guaranteed to handle power loss cleanly, for example. And I’m not too sanguine about hardware not being bricked if I lose power during an fwupd updating the firmware on attached hardware. Maybe a given piece of hardware has a safe, atomic upgrade procedure…and maybe it doesn’t.
That does also mean, if there’s no power backup at all, that one won’t have the system available for the duration of the outage. That may be no big deal, or might be a real pain.
Yeah, I listed it as one possibility, maybe the best I can think of, but also why I’ve got some issues with that route, why it wouldn’t be my preferred route. Maybe it is the best generally available right now.
The “just use a UPS plus a second system” route makes a lot of sense with diesel generator systems, because there the hardware physically cannot come up to speed in time. A generator cannot start in 10ms, so you need a flywheel or battery or some other kind of energy-storage system in place to bridge the gap…but that shouldn’t be a fundamental constraint on those home large-battery backup systems. They don’t have to be equipped with an inverter able to come online in 10ms…but they could. In the generator scenario, it’s simply not an option.
I’d like to, if possible, have the computer have a “unified” view of all of the backing storage systems. In the generator case, the “time remaining” is a function of the fuel in the tank, and I’m pretty sure that it’s not uncommon for someone to be able to have some kind of secondary storage that couldn’t be measured; I remember reading about a New Orleans employee in Hurricane Katrina that stayed behind to keep the datacenter functioning mostly hauling drums of diesel up the stairs to the generator. But that’s not really a fundamental issue with those battery backup systems, not unless someone is planning on hauling more batteries in.
If one gets a UPS and then backs it with a battery backup system, then there are two sets of batteries — one often lead-acid, with a shorter lifespan — and multiple inverters and battery charge controllers in multiple layers in the system. That’s not the end of the world, a “throw some extra money at it” issue, but one is having to get redundant hardware.
I’ll add one other point that might affect people running low-power servers, which I believe some people here are running for low-compute-load stuff like home automation: my past experience is that low-end, low power computers often have (inexpensive) power supplies that are especially intolerant of wall power issues. I have had multiple consumer broadband routers and switches that have gotten into a wonky, manual-reboot-requiring state after brownouts or power loss, even when other computers in the house continued to function without issue. I’d guess that those might be particularly-sensitive to a longer delay in changing over to a backup power source. I would guess that Raspberry Pi-class machines might have power supplies vulnerable to this. I suppose that for devices with standard barrel connectors and voltage levels, one could probably find a more-expensive power supply that can handle dirtier power.
If you run some form of backup power system that powers them, have you had issues with Raspberry Pis or consumer internet routers after power outages?
While laptop batteries may not have aged well, especially if they’re left discharged, one other nice perk is that laptops effectively have an integrated UPS.
Like, the Powerwall things? Yeah, sure, they’re in the same sort of class. I think — not gonna go looking through all of 'em — that the things I linked to above all are intended to have someone plug devices directly into them, and the Powerwalls get wired into the electrical panel, but same basic idea. They aren’t really devices where energy density matters all that much, because once you put the battery somewhere, it probably isn’t going to move much after that.
If people want to get one for the hell of it, I’m not going to stand in their way, but I really don’t think that this product plays well to the strength of sodium-ion batteries.
My understanding is that sodium-ion batteries are not as energy-dense, but are expected to be cheaper per-kilowatt-hour than lithium-based batteries.
But this is a small, very-expensive-relative-to-storage-capacity, portable battery.
I’d think that sodium-ion batteries would be more interesting for things like an alternative to this sort of thing — large-capacity, mostly-non-moved-around batteries used for home backup during power outages, stuff like that. Maybe grid buffering.
Facts are not copyrightable, just their presentation. So I don’t think that it’s possible to say that it’s impossible to summarize material. A court is going to say that some form of summary is legal.
On the other hand, simply taking material and passing it through an AI and producing the same material as the source — which would be an extreme case — is definitely copyright infringement. So there’s no way that a court is going to just say that any output from an AI is legal.
We already have criteria for what’s infringing, whether a work is “derivative” or not.
My bet is that a court is going to tell Brave “no”, and that it’s up to Brave to make sure that any given work it produces isn’t derivative, using existing case law. Like, that’s a pain for AI summary generators, but it kind of comes with the field.
Maybe it’s possible to ask a court for clearer and harder criteria for what makes a work derivative or not, if we expect to be bumping up against the line, but my guess is that summary generators aren’t very impacted by this compared to most AI and non-AI uses. If the criteria get shifted to be a little bit more permissive (“you can have six consecutive words identical to the source material”, say) or less permissive (“you can have three consecutive words identical to the source material”), my guess is that it’s relatively easy for summary generators to update and change their behavior, since I doubt that people are keeping these summaries around.

Well, Woz. You’re famous for doing a universal control panel for another prominent piece of consumer electronics and figuring out how to interface it to lots of different brands.
https://en.wikipedia.org/wiki/Universal_remote
In 1987, the first programmable universal remote control was released. It was called the “CORE” and was created by CL 9, a startup founded by Steve Wozniak, the inventor of the Apple I and Apple II computers.[2]
All you had to do then was to reverse-engineer the infrared protocols used to communicate with the televisions.
I bet that it’s probably possible to figure out a way to have a third-party control panel interface with various auto UIs. Like, build a universal interface, and then just design mounting hardware on a per-car basis? Use Android Auto or CarPlay, OBD-II, and such?
Can Android Auto do climate control?

Sounds like it doesn’t, but may start being able to do so:

Android Auto could be about to turn up the heat (and AC) on car comfort
Climate control may finally be coming to Google’s in-car interface.
Android phones don’t have physical buttons for car features. But…that’s not a physical limitation. Just is a result of reusing a phone as a car panel.
So instead of having third-party car computers being the province of a few hobbyist hardware hackers, there’s an out-of-box solution for everyone? Make the “Wozpanel” or whatever that I just mount in my car? Stick physical buttons on it? Maybe have a case and faceplate that wraps it to match interiors?

Nah, that’s not a problem.
So, if you send a password at some point, someone could theoretically intercept and get the password, and then impersonate you.
PGP keys are public-private. The key never leaves your possession. Instead, the other side asks you to cryptographically sign something using your private key, which they can validate using your public key.
You never expose your private key to any intermediary, and even the other side doesn’t have it.
TOTPs have a shared secret, and generate a temporary passphrase using both time and the secret. Those also protect (mostly) against interception, since the OTP becomes invalid within probably seconds. Just as with PGP keys, the secret does not change. However, unlike PGP, the other side does also have all the information required to authenticate as you.

Those are all mature systems, and I’d say that rankings for games on old systems are reasonably consensus at this point. You can just search for “best system whatever games” and get lists, look for games in genres you like; I’ve had luck doing that in the past, as that avoids a lot of the chaff.
I personally probably have gone back and played Super Metroid the most on the SNES, but depends on what one likes. If you like RPGs from that era, different set of games.
For this ranking of SNES games, as an example:
https://www.ign.com/lists/top-100-snes-games/92
I’d say that probably those games are going to cluster near the top of any list of SNES games.
If he means “4th gen and GBA”, that’d work.
