Heat is bad, but the battery could be positioned below the oven. Disposable would be cheaper.

The burner valves operate mechanically. It has an additional shutoff valve that closes when there's no electrical power. A battery backup for the igniters would be a great feature though - a Li-ion battery stored at half charge would last pretty much forever.

I encountered an infuriating example of the opposite a couple years ago: a gas stove that wouldn't work without electricity.

A gas stove normally operates with a mechanical valve to control gas to each burner, and while modern ones have electronic igniters, it's possible to use a match or the like instead. These assholes went out of their way to add an electronic valve that shuts it off when there's no power. It's probably in the name of safety, but the scenario where someone leaves the valve open without igniting the gas is possible even with power by failing to engage the igniter correctly, and gas is smelly.

I should be able to use a gas stove when there's no electricity or the igniter is broken if I supply my own source of ignition.


For your example of a flashlight, consider one with USB charging. If the charging port or circuit fails, I should be able to easily take out the battery and charge it in another charger (Li-ion charging is pretty standardized). If the battery is dead but the USB port works, I should be able to use it as a USB-powered lamp.

I don't like it because:

  • I want to look at the oil and smell it, not just check the level.
  • I don't know the failure modes for the sensor, so I can't trust that the absence of a complaint from it means the oil level is correct.

I prefer the American version of freedom of speech, which places very strict limits on the government's ability to punish speech. Display of any flag in this way would be protected. We're currently seeing that play out with the US president taking various actions against people who have expressed opinions he doesn't like and getting blocked by the courts at every turn.

That said, Hezbolah is bad and Liam O'Hanna is an asshole for supporting them.

I've driven a couple cars with electronic door poppers and I'm having trouble understanding why anybody would want them. The novelty of accomplishing a routine task by pressing an electronic button instead of pulling a mechanical lever should have worn off in 1985.

Iv had to deal with plenty of people that just moving the windows task bar from the bottom to the top was enough to make them go full stupid and forget they have been using a PC for 20 years.

This is why I drink.

I read Alito's dissent.

His main objection is that the plaintiffs demanded a preliminary injunction with an extremely short deadline upon which they would consider a lack of ruling to be a "constructive denial" which they would appeal, which is highly irregular. He does not meaningfully address the reason for that irregular action, namely the government's attempts to outrun the judicial process and deport people to El Salvador, from which it claims it cannot return them. Alito claims the courts should rely on the government's statement that it would not deport the plaintiffs before their hearing.

Under normal circumstances, Alito would be correct. The government normally doesn't try to do illegal things before the courts can stop them and it would be inappropriate for a plaintiff to apply the extreme time pressure seen here. These are not normal times and the rest of the court appears to recognize that.

In this context, I imagine it means you're not going to freak out when you see something that isn't Windows or Mac OS. Can you move things around with the file manager? Find the wifi settings? Get files off the external hard drive you just plugged in? That's probably sufficient.

Of course there are dozens of possible file managers and wifi widgets. They could be using any of many distributions with a near infinite combination of software. I'm proficient at Linux by nearly any definition, but I haven't checked out recent versions of desktop environments other than the one I use regularly. As long as you can figure out basic computer stuff on something that looks a little different from what you're used to, you should be fine.

Trump appointed three out of nine justices. Three more were appointed by Republicans (Bush 1 and Bush 2), so a 2/3 majority of justices are considered conservative.

Judicial conservatism, however does not always align with political conservatism. Judicial conservatism tends to mean staying close to the original meaning of the text of the law. Some of Trump's actions require creative interpretations of the law; in the case at hand, Trump wants to use a law meant to expel citizens of an enemy country during a war to deport immigrants he accuses of being members of gangs without allowing them to challenge that action in court.

Thomas and Alito dissented, arguing that a creative interpretation of the law should be allowed here; neither is a Trump appointee.

The law operates on precise definitions.

Obviously the forced-reset trigger has pretty much the same effect as a machine gun and common sense suggests that the two should have the same legal status. They don't though because 26 U.S.C. § 5845(b) defines a machine gun as:

Any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot without manual reloading, by a single function of the trigger

and a firearm with a forced reset trigger does require a separate actuation of the trigger for each shot. It is the place of the congress, not the ATF to update the law.

 

For background, it's hard to make a flashlight that works well on both AA batteries (0.8-1.7V potential operating range) and 14500 Li-ion batteries (2.8-4.2V operating range) given that white LEDs need about 3V.

For a long time, companies would make lights designed for AA using a boost driver that increases the output voltage, do just enough so it wouldn't burn out with excessive input voltage, and say that 14500 size Li-ion was "supported". Max output would, indeed be brighter, but low modes were usually far too high, and the flashlights could easily damage batteries that didn't have over-discharge protection.

The Skilhunt M150 was one of the first lights to do a substantially better job. Using a Li-ion battery, it sent the power through a variable-output linear regulator so both battery types could have reasonable modes, and it would shut off to prevent over-discharge. Several competitors use a similar approach today, but linear regulators are inefficient; they just turn the excess voltage to heat.

The ideal solution is either to use a higher-voltage LED configuration and boost the output voltage for both battery types, or to use a driver that can both boost (increase) and buck (decrease) voltage efficiently. The Emisar D3AA is the only light on the market doing AA/14500 with a high-voltage LED configuration (three in series for ~9V), and I believe the new M150 will be the first one using the buck/boost approach (though it's possible Zebralight has done it in the past).

 

Some friends have safety concerns that mean they need to appear digitally as if they're inside the USA while being elsewhere physically. Standard commercial VPNs are easy to detect (else I'd recommend Mullvad), so they need an option that looks like a residential connection.

They could potentially DIY it by leaving a VPN server at a relative's house, but I'm asking here for subscription services. It's best if they have a Mac OS app that's foolproof, with a clear visual indication that it's in use, and a feature to block traffic if the VPN is disconnected.

tl;dr: what's the closest residential VPN to Mullvad?

 

In honor of !flashlight@lemmy.world reaching 3000 members (yes, I know that was a couple weeks ago), I'm giving away this Acebeam T35 swapped to a 3000 Kelvin, 95 CRI Luminus SFT40. While not as bright as the original 5000K, low-CRI LED, it's sure to satisfy anyone who misses the incandescent look, but likes LED power.

Only accounts that have made a post or comment to !flashlight@lemmy.world prior to this post may enter. You should have a shipping address in the USA or EU, which can be a package forwarding company if necessary. Entry ends on Februrary 14 2025 at 20:00 UTC.

To enter, leave a top level comment on this post. I will select the winning entry using a random number generator next Friday.

 

I don't actually want to do this right now, but I do want to know if it's really decentralized yet. Completely looks like it means each of:

  • A client ✅
  • A personal data server ✅
  • A relay ❓
  • Labelers ✅
  • Feed generators ✅

It looks like the relay might be the bottleneck. If I'm understanding the protocol correctly, a relay could consume less than the whole network so it doesn't have to be ridiculously expensive to operate, but I'm not finding examples of people doing it.

 

I fear if I carry anything else today, I'll lose it or cut myself with it.

I've been self-hosting email with Maddy for a bit, but haven't shared any of the addresses widely yet in part because I haven't set up a spam filter. I'm pleased with Maddy; there's much less to learn to get a server up and running with sane default behavior than with the email software of old.

Ideally, I'd like to go beyond just spam filtering and have something with arbitrary categories like newsletters and password resets. I would prefer that it learn categories when I move messages to IMAP folders from a mail client. Maddy can feed messages into arbitrary programs and pick a destination folder based on their output.

Web searches turn up a ton of classification programs, most of which seem to be more interested in playing accuracy golf with well-known corpora than expanding functionality beyond simple spam filtering.
