Asian MIT grad asks AI to make her photo more ‘professional,’ gets turned into white woman
  • Sounds like they fucked up training the AI then. For a user it doesn't matter whether the AI is designed poorly or trained poorly, it's behaving poorly.

  • AMD unveils its first laptop processor with 3D V-Cache
  • Probably way better and way more expensive.

  • J. Robert Oppenheimer’s Grandson Says He “Definitely Would Have Removed” One Scene in Christopher Nolan’s Film
  • The Wikipedia article seems to say something similar happened, but in a different way.

  • Realtors: Buyers Will Pay Extra for Walkable Neighborhoods
  • A reasonable length survey will never "paint a full picture". Maybe what they're trying to show is that there are a lot more people who value walkability more than is currently assumed. In most of the US you can either chose a super high density walkable area in a condo tower or a house in a car based suburb. It's possible to design neighborhoods that are walkable and can provide a reasonable amount of private outdoor space, and what this shows is people would be willing to pay for it!

  • Today i installed arch linux for the first time
  • What's the point if they still have AMD, Intel, Nvidia, Qualcomm, etc. chips on them?

  • YSK that a lot of common questions/complaints about Lemmy are presently answered by kbin
  • Yeah the current challenge with searching is if no one has subscribed to a magazine or user on another instance, you have to search the exact name@domain to get it to show up. Ideally Kbin instances would implement a user bot that subscribes to all the users and communities it can scrape from all federated instances until this search limitation is fixed.

  • Which is the most satisfying IO connector system, in your opinion?
  • I'm a sucker for any connector that has a nice solid spring load mechanism that pops into place when properly connected. It should sound like a movie sound effect of a gun being reloaded.

    I've also used some really nice quick release steering wheels, like on race cars or racing sims, where they have a spline connector with a tight fit and a good spring load.

  • In-N-Out Burger bans employees from wearing masks unless they have a doctor's note
  • They may be Californian but they're still conservative. They've got Bible verses on their cups. They're a for profit business. They think it will help their revenue, since they know more people hate masks than will leave if there are no masks.

  • They're edible if you get them "well done". Then they're like rectangular potato chips.

  • The carbon free rock is replacing limestone in the manufacturing process, not the sand. Sand is added to cement, along with rocks and other aggregates, to form concrete.

    From what I can tell, the way this might be bad is that the carbon free rock may not exist in significant quantity. If it does, it will be mined in the same way as limestone, so that's just a wash not a bad thing. If the rock they need doesn't really exist they have to buy it from someone else who makes it from readily available materials. In that case, it could be green washing, where the company can claim "our process doesn't release much carbon compared to the traditional process" but in reality the total carbon released to create the cement - from mining to processing to pouring - could be similar.

  • Hyperloop is the future
  • Having multiple, semisolated compartments in a Hyperloop train is entirely reasonable. There's definitely room in a traincar for the occupants of a compartment that's on fire to move to another compartment for emergency purposes.

    Evacuation points would be defined every so often (say every few miles) such that the train could come to an emergency stop within one, seal doors on each side and let air in. This would take a few minutes, but so does landing a plane or stopping a high speed train.

    Bottom line is that fire safety is, to me at least, an entirely solvable problem. The biggest problem with Hyperloop, I think, is that given the materials for the vacuum sealed tube and the energy required to hold that vacuum, it is just so unlikely to be more efficient than a maglev. For medium distance travel, even standard high speed rail is good enough to replace planes, so we don't need the extra speed for ~500 mile distances. For longer distances where high speed rail is super slow or impossible, such as across continents and oceans the cost of building the vacuum tube will be so costly that it would take something like a complete ban of non-renewable fuels in aircraft for it to be a consideration. Even then, I think it could end up being cheaper to develop and use renewable fuels for aircraft.

  • Hyperloop is the future
  • Hyperloop is more of a concept for high-speed trains/pods in a vacuum tube that go between two major cities (in a loop, hyper fast). It got conflated with his bs tunneling project (the tunnels are smaller, that's the only "innovation"), but a Hyperloop would be much more likely to be primarily elevated like a high speed train.

  • Hyperloop is the future
  • It is much harder for fire to exist without air. There are some self oxidizing fires, but it should be relatively easy to avoid those materials. For fires inside the vehicle, there are some existing fire protection protocols that could be followed. There have been fires on the International Space Station and they couldn't exactly run outside either.

  • Meet Microsoft Office’s new default font: Aptos
  • I never really liked Calibri at any font size above like 14 pt maybe? Hopefully this new one is better than Arial and I can switch all my PowerPoints over to it.

  • Pocket Casts Plus increases subscription pricing to $33.99 from $10
  • Tbh you might be able to come back go pocket casts. They added a bunch of functionality back over time. Can't remember what it used to be like anymore, but it works for me.

    I have a free account and do have access to the filters. You can filter by podcast, started/not started, duration, etc. It may still not work for your needs though.

  • What's the best way to make iced coffee?
  • If you don't have anything other than a pourover, you can still make good iced coffee. You'll brew with 60% of the water in the pourover and 40% as ice. You can put the ice in your vessel and brew directly onto it or brew into a mug or carafe and allow it to cool a bit before pouring over ice.

  • [META] The merger from lemmy.world has locked out k.bin members. [FIXED]
  • Yo, I'm a Kbin.social member and can report we're federating now

  • Is this the technology community or the Twitter news community?

    Chill out, we get it, Twitter sucks.

    Is the "top" sorting option working as intended?

    Maybe I'm just not aware of how the "top" sorting is supposed to work, but it isn't making sense to me right now. I was just looking at top of 6h, and noticed some strange stuff.

    • top thread had about half the favorites as the 2nd post but a few less boosts. Both were newer than 6h.
    • a thread with only a few favorites and no boosts was just hanging out amongst posts with 50-100 favorites.

    Are favorites and boosts accounted for differently in sorting? What about dislikes?

    Tesla owners are typically white men earning six figures
  • On one had we've got links to the department of energy and to Wikipedia. And just some hand waving on the other hand.

  • Tesla owners are typically white men earning six figures
  • If we're talking approaching fundamental limits, Hydrogen fuel cell is not a great comparison. A high pressure tank can only get so light, even with linerless ultra high strength carbon fiber pressure vessels, the mass of the vessel is maybe 6-10x the mass of the hydrogen it carries. To increase specific energy there you need to go to cryogenics which is a whole technology leap and has its own set of challenges.

    Battery tech has been improving more than you have seen, clearly. Since '08, lithium batteries have increased energy density by 8x (https://www.energy.gov/eere/vehicles/articles/fotw-1234-april-18-2022-volumetric-energy-density-lithium-ion-batteries). The best LiPo batteries are around 0.9MJ/kg right now, but there's no fundamental reason a battery couldn't achieve 9MJ/kg. Lithium-air batteries could theoretically achieve way higher energy density than that even (https://en.m.wikipedia.org/wiki/Lithium%E2%80%93air_battery), and have already been demonstrated in a lab to achieve more than 5x what current commercial automotive batteries are doing.

  • UK weather: hottest June since records began - Met Office
  • If your windows are compatible, it could be a good idea to pre-emptively buy a window ac. They are pretty efficient and it's not a crazy amount of energy to just cool one room (bedroom probably). The trick is to only use it when necessary and set the temp to 26-28C.
