    The IT talent gap surpassed 4.7 million unfilled cybersecurity roles and widened 19% in a single year. MSPs that keep trying to hire through it are losing clients before they lose payroll. The MSPs that are scaling are treating delivery capacity as infrastructure rather than a staffing problem.

  • BGP-Based Congestion Signaling for Leaf-Spine Data Center Fabrics

    This story was originally published on HackerNoon at: https://hackernoon.com/bgp-based-congestion-signaling-for-leaf-spine-data-center-fabrics.


    A proposal to use BGP as a fabric-wide congestion signaling mechanism, reducing AI workload tail latency and improving ECMP path balance.

    This article proposes BGP-CN, a congestion notification mechanism that uses BGP extended communities to distribute congestion information across leaf-spine data center fabrics. Rather than relying solely on local mechanisms such as ECN, PFC, and DCQCN, BGP-CN provides fabric-wide visibility, allowing switches to proactively adjust ECMP weights before congestion spreads. Prototype testing on a SONiC/FRR environment showed a 47% reduction in P99 tail latency and a 63% improvement in path utilization balance.

  • How I Built a Pipeline to Restore Old B&W Photos to 4K Color Using Open-Source AI

    This story was originally published on HackerNoon at: https://hackernoon.com/how-i-built-a-pipeline-to-restore-old-bandw-photos-to-4k-color-using-open-source-ai.


    Turn old B&W photos into 4K color with open-source AI. I tested 8 tools across 6 GPUs — only one produced stunning results in 42 seconds.

    I tested 8 different open-source AI upscalers and restoration tools to find the best pipeline for converting old black-and-white film footage into 4K colorized images for a YouTube history channel. After days of testing on rented GPU servers, the winning pipeline is surprisingly simple: Qwen-Image-Edit-2511 does everything — upscale, restore, AND colorize — in a single prompt, in under 60 seconds.

    - AI not only revolutionized software development – it brought significant new problems with it.
    - A flood of unreviewed PRs and AI breaking down on complex requirements are among the most pressing.
    - The biggest threat: AI now gives anyone the ability to find and exploit software vulnerabilities in seconds.
    - All these problems point to one solution: visual programming languages – and here is why.

    As technology automates the tedious "counting" in our jobs, like cycle-counting for early programmers, it forces us to focus on the higher-level "deciding" – judging the quality and purpose of the work. The author argues that AI is now doing this for everyone, turning us all into editors who must answer the ultimate question: "Is this good, and how do you know?"
