  3. excalidraw

    Virtual whiteboard for sketching hand-drawn like diagrams

    Project mention: Spain and Portugal Without Energy | news.ycombinator.com | 2025-04-28

    In my area, "buckets" of average load are prepared ahead of time in coordination between the transporter (who gives the order to shed), the distributer (who implements the shedding operation as close to consumers as possible), and representatives of the state (who define priority areas that can't be load-shed, or that should be load-shed last).

    When yhe time comes, you just shed enough "buckets" to stabilize. Load shedding is not a precise task, when you're at that point, you'd rather load a few more megawatt and be safe, than play with the limits and be sorry.

    > So how do grid operators know what amount of load will be cut if they disconnect point A123

    Opening a line within the grid isn't used to shed load, as the grid is mainly redundant. It's used 1) to protect the line itself (either by letting it trip, or by opening it preventively), or 2) to force power to flow differently through the network, by modifying its impedance. Opening a line from the transport network is not a way to load shed.

    In this totally random example [1], opening the line A-B increases impedance in part of the network, forcing power to re-route by another path, and reduces the load on a separate line that was overloaded.

    Project mention: Top 5 Free React UI Libraries to Use in 2025 | dev.to | 2025-05-01

    MUI is the OG of UI component libraries. They’ve been at the top back since when Bootstrap was a contender and are still maintaining a top spot in the era of Tailwind and other UI libraries. With more than 95k GitHub stars (and counting), and top companies using it in production, I’d say this is the open-source React component library with the most stars. MUI also has paid components available for enterprise users.

    Project mention: Show HN: A pure WebGL image editor with filters, crop and perspective correction | news.ycombinator.com | 2025-04-28

    thanks. It started as a proof of concept for a custom reactivity engine (based on signals and tagged template literals). But while at it I realised I needed something quick and easy for my needs.

    I already have a prototype for a self-hosted photogallery that integrates this editor (something like https://immich.app to give you an idea). But it's still to early to share
