Slash Data Center Energy Use With This One Weird Trick

By changing only thirty lines of Linux kernel code, these engineers saved up to 30% of energy costs for certain applications. 30 for 30!

    A good improvement, but an important distinction from the headline alone:

    This energy savings comes with a caveat. “It is sort of a best case because the 30 percent applies to the network stack or communication part of it,” Karsten explains. “If an application primarily does that, then it will see 30 percent improvement. If the application does a lot of other things and only occasionally uses the network, then the 30 percent will shrink to a smaller value.”

    Kill off crypto mining and you’ll save even more. Charge a premium for use of LLMs and you’ll be orders of magnitude less wasteful.

    This was an interesting read. Also, if you’re willing to put up with some sacrifices, disabling Google Play services on your Android phone, or installing Lineage OS without Google services at all, will make your phone both run faster and have way better battery life. As an example, I own the Oneplus Nord N20 5G, and when I pulled it out of the box, it was super laggy and awful. And by installing Lineage OS on it with no Google Play services, it works fabulous.

      Honestly, even if you need some Google services, just get things like gapp (or whatever its called, forgot) and you are good to go.

      I want to try GrapheneOS, but no one I know owns any old (or new) pixel device and compiling and running as emulator (like for developing purposes) requires like 500gb of storage on PC for it.

      PostMarketOS sounded fun but I couldn’t get waydroid to start without crashing

        GAPPS have Google Play services and the other one that I can’t think of the name of right offhand mimics play services. I don’t need play services for anything since I run open source software on my device and have not had a Google account in over two years now.

          MicroG?

          I still need it for 2 games I like to play on my phone, maybe other things too, it was only recently that I started slowly moving away from being dependent on google

            That’s the one. It just would not come to me in the moment. I don’t have GAPPS or MicroG installed on my device at all. My view is that if an app won’t run without it, then I didn’t need that app to start with.

            Edit: Not having those is basically an immunization against crappy apps that want to steal your data and mine you for profit.
