  • I’m concerned about the cuts but this article isn’t worth reading if it’s not going to talk about our realistic options.

    What happens if we don’t increase our defense spending to match NATO targets? In light of our general lack of military spending, the US’s aggression, Russia’s aggression, and the way that China is posturing towards Taiwan, it quite frankly seems like to would be asinine to not increase our defense spending.

    If you want to make the argument for taxing the rich to maintain both, then do so, and explain how you will do so while preventing capital flight, but this author is just listing cuts to government departments because that sounds bad and not bothering to actually think through or make any judgements on our realistic paths forward.

    Based on the reasoning presented in the article, and having heard Carney talk a few times, I’m fairly confident he has spent more time seriously considering our options than they have.


  • Neat to prove it for sure, but I feel like the scientists might be misrepresenting previous consensus to make their conclusions sound more momentous.

    Like did Raven experts really think that Ravens just followed wolves 24/7 to scavenge?

    … Ravens, the only animal other then humans known to be posses linguistic displacement (the ability to communicate ideas about locations that are far away in time and space), the ones that memorize hundreds of locations that other Ravens bury food so that they can later steal it, a literal top 5 animal in terms of cleverness creativity and problem solving, that can travel in any arbitrary direction of 3D space…

    … Experts of these creatures really thought that they just followed wolves 24/7 to pick up the scraps?


  • Because most articles you see online are written to get clicks, not to actually inform you, and no one particularly cares to defend meta, so no one bothers correcting them.

    But saying that meta spent $80B on the metaverse and is now shutting it down because they’re shutting down horizon worlds is flat out disingenuous.

    First of all, let’s be clear, the $80B number is the accumulated losses of the entire Reality Labs division over the past 6 years. Reality Labs includes not just the Oculus teams that cover AR and VR, but also other teams like the cancelled Portal hardware / software, and their Facebook Spark AR (closer to snapchat filters).

    Second of all, those losses include

    • all the R&D costs of developing the Quest 2, Quest Pro, Quest 3, the various Ray Ban collab glasses, and their unreleased future headsets / AR glasses.
      • The R&D costs related to the controllers and input devices.
      • Some of the R&D costs for the display technology used.
      • The R&D costs for developing machine learning based 6DOF inside-out tracking, and hand tracking.
      • Developing and customizing Android into a viable operating system for all their devices.
      • Subsidizing the cost of every VR headset they sold to grow the market
      • Developing VR utility apps like the browser, the Link system, the HDMI in / capture card system, the desktop link apps, etc.
      • Buying a bunch of VR studios and games like Beat Saber, that mountain boxing game, etc
      • developing multiple top quality VR games like Assassin’s Creed, Batman, and a Resident Evil 4 remake
      • And yes, developing and supporting their social VR app, Horizon Worlds, which has never been as popular as third party alternatives.

    Out of all of that, they have shut down just Horizon Worlds, and the VR studios / games they bought. All of the hardware and platform work is still ongoing.

    And what does it buy them? The potential opportunity to be Google or Apple once AR glasses become light and powerful enough to be common place. Do you know how many billions of dollars Google and Apple have made from being the dominant mobile OS companies? Microsoft rode the Windows train for decades before switching to Azure. Meta is buying a chance at becoming that for AR.


  • You can also do this with Lunar, or with the paid version of BetterDisplay, and they also support controlling external monitors via DDC/CI.

    I personally despise MacOS, but the MiniLED displays in MacBooks have fully changed what I prioritize when buying displays.

    It’s so much more pleasant to be in a bright room (or outside), but that’s only feasible if your screen can output like 1000nits of brightness which few can outside of MiniLED displays.






  • The biggest problem IMO is the fact that all our power generation technology comes down to “boil water to turn turbine”. How we generate the heat changes, but not how we turn it into electricity.

    Technically the ones that use steam to spin turbines are:

    • Coal plants
    • Gas plant
    • Thermal Solar Plants
    • Nuclear Fission Plants
    • Nuclear Fusion Plants

    Then you have ones that spin turbines, but using other methods:

    • Hydro dams and tidal power - use water
    • Engines / Generators - use controlled explosions
    • Wind Turbines - use wind

    Then you have the few that truly don’t use spinning turbines:

    • Solar Panels - they use semi-conductors specially designed so that light causes the electrons in the material to start flowing, directly creating usable electricity.

    • Piezo Electrics - similar semiconductors that react to material stress (bending etc) and cause electrons to flow

    • Batteries & Fuel Cells - store power in chemical form, and the reactions cause the electrons to flow directly

    • (Proposed) Direct Energy Converters - experimental devices long proposed for nuclear fusion reactors that can directly produce flowing electrons. There’s been recent research investigating doing this with fission reactors as well.
