  • A typical data center rack holds about 40 servers, each with at least two networking interfaces. According to Boote, the Ethernet interfaces of a single rack draw 160 watts in total.

    “Reducing the power draw of a data center, which may have hundreds or thousands of racks, would be akin to an energy savings of switching a building from incandescent to more energy efficient LED lighting and be well worth the investment,” he told LinuxInsider.

    According to Boote, this optimization fixes a part of the kernel written when lower-speed Ethernet interfaces drew a fraction of today’s electrical needs. The networking stack design did not account for the growing power budget required by modern networking interfaces.

    “By changing the priority of how the computers schedule tasks during high bandwidth events, a computer can better deal with networking traffic and prioritize energy expenditure in a way that makes sense for modern hardware and architectures,” he reasoned.


  • Oh boy, where do I even start? This comment is wrong in multiple ways. Let’s break it down:

    1. “The way triangulation works is by essentially measuring distance.”

      • Nope. This describes trilateration, not triangulation.
      • Triangulation uses angles, while trilateration uses distances. GPS works via trilateration.
    2. “1 satellite distance puts you anywhere in a radius (circle) of that satellite.”

      • Kind of, but missing a crucial detail:
        • A single satellite defines a sphere around itself (not just a circle—you exist in 3D space).
    3. “2 Satellites puts you at 1 of 2 locations where those radiuses intersect.”

      • Wrong. Two satellite distance spheres intersect to form a circle, not just two points.
    4. “3 satellites gives you a single location.”

      • Mostly right, but incomplete.
      • In theory, three satellites narrow it down to two possible points, but one is often out in space or somewhere unrealistic, so it can often be ruled out.
      • However, because your device lacks an atomic clock, it typically requires four satellites to synchronize time properly.
    5. “That’s why it’s called triangulation. Tri = 3”

      • Nope. GPS does NOT use triangulation.
      • The “tri” in triangulation comes from angles, not the number of satellites. GPS uses trilateration, which is based on measuring distances, not angles.

    Final Verdict

    This comment is a trainwreck of incorrect terms and flawed explanations. If they meant “trilateration,” at least part of it would make sense, but calling it “triangulation” completely ruins their credibility.

    So, in short? No, their comment is very incorrect. 🚨







  • I don’t disagree, but what more could Google do here? They had a flaw in their system that required two completely different services at Google in order to exploit and the result is an email address, not access to the account itself. Google also is actively paying for people to help them find these issues. I think they did a stellar job here, but of course being perfect with the security if the software implementations is always the best case.


  • OTF receives the majority of its funding from the U.S. government via the U.S. Agency for Global Media (USAGM). Funding is appropriated for OTF through the annual  Department of State, Foreign Operations, and Related Programs appropriations and provided to OTF via a grant agreement from USAGM.

    For FY 2023, Congress allocated $90.5 million for programs to promote Internet freedom globally, representing a $13 million increase from FY 2022. Of the funds allocated for Internet freedom, $40 million was designated for OTF. Per the appropriations, all Congressional funding provided to OTF is used to support “programs to promote Internet freedom globally.” In addition to helping to further OTF’s mission, this funding increase is also further recognition of the increasing need for the tools and technologies OTF supports.

    In addition to funding from USAGM, OTF also accepts funding from other mission-aligned donors for discrete Funds, Labs, or Fellowships. For example, OTF’s FOSS Sustainability Fund is supported in part by funding from Schmidt Futures’ Plaintext Group, Okta for Good, and the Github Foundation.
