Heartbreaking: The Worst Person You Know Just Made A Great Point

I fear I’m gonna get a lot of mileage out of that headline over the next 4 years.

Also good parents don’t let tweens have unsupervised access to a handgun…

iOS shows the voicemail transcript in realtime as they’re leaving the message.

Science 2: Electroweak Boogaloo

Honestly this sounds like user error. From one of the links in the article:

As the journalist and Apple Store staff tested, if you insert the wrong passcode for 1 to 5 times, there will only be red notifications saying the passcode is wrong, and you needn’t wait to give it another try.

For the 6th time you insert a wrong passcode, it will report, “iPhone is disabled, try again in 1 minute”. And the phone will be locked, and you won’t be able to insert passcode again until 1 minute later.

For the 7th time, the iPhone will show, “iPhone is disabled, try again in 5 minutes”.

For the 8th time, the iPhone will be locked for 15 minutes, and for the 9th time, it will be locked for 60 minutes to insert passcode again.

If you insert the wrong passcode for 10th time, the iPhone will be disabled and you will have to connect it to iTunes to unlock.

Apparently if you jailbreak the iPhone the delays aren’t set correctly (or at least that was the case 10 years ago)?

On top of that, the user couldn’t just wipe the phone because they didn’t want to lose a video that wasn’t backed up anywhere else.

widely distributed them. Many of them went to civilians for legitimate purposes.

Source?

There are many sources because it’s been widely reported. Here’s one: reuters.

It’s been widely reported, here’s a reuters source.

Seems unlikely considering only pagers belonging to Hezbollah had the explosives added.

Eh, theorists just work in units where they’re all 1 anyway. And experimentalists round to to the nearest order of magnitude lol

The volumetric energy density is 60% of lithium ion batteries, but the energy density per kg is more like 75% since the batteries are lighter. Assuming that scales to the ev range, that’s probably sufficient for a lot of use cases.

I have one of these. The sous vide cooker itself is very nice and easy to use, I’d highly recommend it. The app is a bit clunky and not necessary to use the device. I certainly wouldn’t pay $2 a month for it.

The app lets you set a temperature and cook time, but you can also do this using the buttons on the cooker. Sometimes the WiFi pairing is finicky, so honestly I skip the app half the time. The app also lets you view and write recipes. I guess the big advantage is you can click “start cooking” and it automatically sets the device temp and time, but doing it manually isn’t much harder. I’m also not wowed by the in-app recipe selection, and generally just get recipes from the internet.

Beehaw had been around for a few years before lemmy.world launched. They have a specific sort of space they want to create, so good for them for being able to maintain it.

That’s too straightforward - this is google after all.

There’ll be a new product that integrates this feature and they’ll call it Google Slides, while rebranding the old “Slides” as Google Presentations. Then in a few years they’ll kill off the new Google Slides, leaving only Google Presentations and tons of confused users.

The bar patron is a classic optical illusion.

There absolutely are, but I’m not super familiar with all of the consequences of majorana neutrinos. /u/drail@fedia.io might be able to provide a better answer. My background is experimental nuclear physics, so I’m familiar a lot of experiments searching for beyond the standard model physics, but less so with the theory motivation.

One consequence of neutrinos being their own antiparticles is that it breaks lepton number conservation. This also breaks chiral symmetry, since all neutrinos are right-handed and anti-neutrinos are left-handed. This observation would also imply that neutrinos have mass - which is assumed but would be a really big deal to prove.

Yeah it’s one of those terms that’s unfortunately been co-opted for another definition. Definitely made some of my google searches in grad school feel icky… The physics terminology came first though!

Despite space being “empty” there’s still a surprising amount of stuff streaming through it. There are protons, electrons, carbon nuclei, etc constantly slamming into the Earth’s atmosphere, producing showers of radiation. These cosmic rays are the reason so many sensitive physics experiments ( like dark matter and neutrinoless double beta decay searches) are located deep underground. The earth is a good shield against these cosmic backgrounds.

Even if there was an “isolated” antimatter galaxy, it would get bombarded with matter in the form of cosmic rays. The annihilation photons are a really distinct signal that would be hard to miss. There are a number of gamma ray telescopes in space that map out sources of gammas, and they would have detected an antimatter galaxy if it existed.

If the antimatter galaxies are so far away that they’re beyond the visible universe, then there’s still the big question of why there was a segregation of matter and antimatter early on.

You’re not alone; matter-antimatter asymmetry is one of the big open questions in physics. Most particle processes treat matter and antimatter identically, but there are a few areas where matter and antimatter have slightly different interactions. These occurrences are violations of Charge Parity symmetry aka CP Violation.

There must have been a certain amount of CP violation during the early phases of the Big Bang to explain our matter-dominated universe. But the known amounts of CP Violation are nowhere near enough to explain the asymmetry in matter and antimatter. There are some proposed mechanisms that would violate CP symmetry in sufficient quantities, but these haven’t been experimentally observed. There are ongoing searches to detect these processes, or related processes that would be possible if these existed. Neutrinoless double beta decay searches are one example of these detection efforts.

In summary, there’s a guaranteed Nobel Prize to whoever can answer your question.
