Sure, but electrolysis is only around 30% efficient — so you need 3 units of energy to produce the hydrogen to drive a vehicle x distance, whereas a BEV would only need one unit to travel the same distance.

That is, you can use the electricity generated from that nuclear power plant to drive three times the distance with a fleet of BEVs than you’ll get out of a fleet of hydrogen powered vehicles.

Ask your dad if he knows why people steal catalytic converters from ICE vehicles.

For anyone not aware, it’s because they’re filled with Palladium — a precious rare earth metal. One where 40% of the world’s supply comes from Russia.

Palladium’s prevalence in the Earth’s crust is about 0.015 ppm. Lithium’s prevalence is 20 ppm — or around 1300 times more abundant than palladium. Which is why people steal catalytic converters in the first place.

The Fediverse by design prevents this, while the internet of the old age had little if any guardrails against this specially since the platforms never really federated with another.

I see someone is too young to remember USENET.

The Fediverse is a bit more like the old USENET days in some regards, but ultimately if it ever becomes more popular the same assholes that ruin other online experiences will also wind up here.

What made the Internet more exciting 30 years ago was that it was mostly comprised of the well educated and dedicated hobbyists, who had it in their best interest to generally keep things decent. We didn’t have the uber-lock-in of a handful of massive companies running everything.

It’s all Eternal September. There’s no going back at this point — any new medium that becomes popular will attract the same forces making the current Internet worse.

Depends on what you mean by “back in the day”. So far as I know you could be ~30, and “back in the day” for you is the 2005 era.

For some of us “back in the day” is more like the early 90’s (and even earlier than that if we want to include other online services, like BBS’s) — and the difference since Eternal September is pretty stark (in both good and bad ways).

It's horrible she was denied when there was a liver already available.

Any full cadaver liver that could have gone to this woman didn’t get thrown into the garbage — it went to someone else who would have died without it.

As for the living donor liver her boyfriend offered, even though he was a match her level of liver failure likely meant that the partial liver her boyfriend could have donated wouldn’t have been successful. Living donors still need a liver for themselves, and we each only have one full liver — so the best they could have done is given her half a liver. Her condition was too poor for this to have a likely positive outcome, which was why this was also denied.

It sucks, but there aren’t enough donor livers for everyone who needs one. The cadaver liver she was denied however would have gone on to save the life of someone else you’re not hearing about in the press — someone else who may have died without it.

If the unfairness of it all upsets you that much, then make sure you’ve signed your organ donor card, and make sure your family members know and understand your desire to be an organ donor. And encourage the people you know to do the same. This is only a problem because there aren’t enough donor livers for everyone — when you have n livers, at best you can save n lives — and thus having a larger number of donor livers allows for more lives to be saved, with fewer qualifications.

I’ve been a fan for a really long time — Astro Bot Rescue Mission is still one of my favourite VR games ever. Team Asobi really knocked this one out of the park it seems. I’m happy for their success — and happy for us to have such a great game to play (I too only got an hour in tonight — had to put my daughter to bed, and she wants to play with me so I had to put it away until tomorrow).

 

For anyone who missed it (or who wasn’t aware), there was a “countdown party” in ASTRO’s PLAYROOM for the release of the new Astro Bot game. Not knowing what to expect I captured the last 10 minutes prior to release; for those who want to fast forward more begins to happen around the 9 minute mark, with a countdown ten seconds prior to the new game being available to play. Enjoy!

There are a lot of manufacturer-agnostic smart home devices out there, and with just a tiny bit of research online it’s not difficult to avoid anything that is overly tied to a cloud service. Z-wave, ZigBee, Thread/Matter devices are all locally controlled and don’t require a specific companies app or environment — it’s only really the cheapest, bottom-of-the-barrel WiFi based devices that rely on cloud services that you have to be careful of. As with anything, you get what you pay for.

Even if the Internet were destroyed tomorrow, my smart door locks would continue to function — not only are they Z-wave based (so local control using a documented protocol which has Open Source drivers available), but they work even if not “connected”. I can even add new door codes via the touchscreen interface if I wanted to.

The garage door scenario can be a bit more tricky, as there aren’t a lot of good “open” options out there. However, AFAIK all of them continue to work as a traditional garage door opener if the online service becomes unavailable. I have a smart Liftmaster garage door opener (which came with the house when we bought it), and while it’s manufacturer has done some shenanigans in regards to their API to force everyone to use their app (which doesn’t integrate with anything), it still works as a traditional non-smart garage door opener. The button in the garage still works, as does the remote on the outside of the garage, the remotes it came with, and the Homelink integration in both of our vehicles.

With my IONIQ 5, the online features while nice are mostly just a bonus. The car still drives without them, the climate control still works without being online — most of what I lose are “nice-to-have” features like remote door lock/unlock, live weather forecasts, calendar integration, and remote climate control. But it isn’t as if the car stops being drivable if the online service goes down. And besides which, so long as CarPlay and Android Auto are supported, I can always rely on them instead for many of the same functions.

Some cars have much more integration than mine — and the loss of those services may be more annoying.

The people who follow those religions would disagree. The Copts even have their own Pope, so it’s pretty hard to consider them “Catholic” in any normal sense of the word.

You don’t have to run in Ring 0 to detect events occurring in Ring 0.

Besides which, as kexts are being obsoleted by Apple getting code to run inside Ring 0 in macOS that isn’t from Apple itself is going to be extremely difficult.

Yes. But what if the world was 1/3rd Linux, 1/3rd windows, 1/3rd OSX?

The 1/3 running macOS (they haven’t called in OS X in many years now) wouldn’t have to worry, because Apple provides kernel event access for security tools running in user space. The CrowdStrike Falcon Sensor driver on macOS runs as a System Extension, and runs 100% in user space (“Ring 3” in Intel parlance) only — so if it misbehaves, the kernel can just shut it down and continue on its merry way.

The problem with Windows (and to a certain extend Linux) is that Falcon Sensor needs to run in kernel mode (Ring 0) on those OS’s, and if it fucks up you lose all guarantees that the kernel and all of the apps running on the system haven’t been fucked with, hence the need for a full system crash/shutdown. The driver can (and did) put these systems in an indeterministic state. But that can’t happen on modern macOS with modern System Extensions.

Actually pretty much the only Christians until Martin Luther and the Reformation.

I think the Coptic Church (AD 41), Greek Orthodox Church (1st century AD), Syriac Church (514 AD) would like to have a word.
