    The researchers designed their bio-inspired robotic fish to mimic the tail propulsion of a swimming fish, and conducted experiments at varying tail beat frequencies and flow speeds. In nature, fish positioned at the front of a school beat their tails with greater frequency, creating a wake in which their followers gather. The followers display a notably slower frequency of tail movement, leading researchers to believe that the followers are enjoying a hydrodynamic advantage from the leaders’ efforts.

    In an attempt to create a robotic leader, Marras and Porfiri placed their robot in a water tunnel with a golden shiner school. First, they allowed the robot to remain still, and unsurprisingly, the “dummy” fish attracted little attention. When the robot simulated the familiar tail movement of a leader fish, however, members of the school assumed the behavior patterns they exhibit in the wild, slowing their tails and following the robotic leader.

  • No Mercy
  • bro thinking a chromecast OS gonna run in google servers 💀, micro kernels has their utility in embedded system, we know, saying that they are replacement for monolithic kernel is dumb, also companies can't do different/hacks project anymore?

  • No Mercy
  • you don't need a micro kernel to install medules, nor to make a crash in certain module don't bring the kernel down, you program it isolated, they don't do that now because it's unecessary, but android do that, and there's work being doing in that way

    the thing is that it's harder todo that, that's why no one does, but not impossible, you also need to give the kernel the foundation to support that

  • No Mercy
  • nah, you can have micro-kernel features on linux, but you can't have monolithc kernel features on microkernel, there's zero arguments in favor of a micro kernel, except being a novel project

  • Is this NOT about 'saving democracy'?!
  • oh no, that's is something that a first world country would do, like brasil, be happy in your corporatocracy that's how your system is designed anyway, there's a very fucking good reason why any democratic country outlaw company donation to politican party

  • Ubisoft is still trying to make NFTs happen
  • bro, just point at Valve, they did all of that without stupid NFTs almost 20 years ago with CS and TF2, all of that, without blockchain and shit, the algument of NFT being descentralized is okaysh, but claiming that you can't do that without NFT, or no one ever did is plain wrong

  • Will Linux’s New run0 Command Run sudo Out of Town?
  • But, I may be wrong, please, tell us how exactly a move to systemd has benefited companies enough that it would make the effort and expense to make a distro move to sytemd, let alone a majority of distros, worth it.

    you're putting to much thought in something that even the guy who you're asking didn't

  • question: what's happening, who is Sarah, who is janette, what's TBP??? lol

    Hello!, so i have 2 services in my .config/systemd/user one of them is named flatpak-update.service, and the other find-and-delete.service. When i write journalctl --user-unit flatpak it autocomplete like any other command in bash, but if i try the same with journalctl --user-unit find it don't autocomplete, as the service didn't exist, but if i type journalctl --user-unit find-and-delete.service i list the service logs as normal, why it isn't autocompleting the name?, thank for any answer or suggestion
