    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Windows 95 in Electron

    Windows 95 in Electron

    windows95 in Electron is a quirky, nostalgia-driven project that ports a complete emulation of Microsoft Windows 95 into a desktop application that runs on modern operating systems like Windows, macOS, and Linux.

Users can interact with familiar UI elements like the Start menu, File Explorer, and retro applications in a sandboxed environment that evokes early personal computing. Beyond being a playful trip down memory lane, the project demonstrates how emulation can be packaged using modern frameworks & how legacy operating systems can be encapsulated as distributable desktop experiences. ...
