    Stretchly

    The break time reminder app

    Stretchly is a cross-platform open-source app that reminds you to take breaks when working on your computer. When you run Stretchly for the first time, you are presented with a Welcome window that allows you to change the language, review the preferences, view the online tutorial or simply continue with the default preferences. Stretchly itself lives in your tray, only displaying a reminder window from time to time, which contains an idea for a break. By default, there is a 20 second Mini Break every 10 minutes and a 5 minute Long Break every 30 minutes (after 2 Mini Breaks). You'll be notified 10 seconds before a Mini Break (and 30 seconds before a Long Break) so that you can prepare to pause your work. When a break starts, you can postpone it once for 2 minutes (Mini Breaks) or 5 minutes (Long Breaks). Then, after a specific time interval passes, you can skip the break. Both actions are available by clicking on the link at the bottom of window.

    Make Your Observability Stack Effortless

    For Software Engineers, DevOps, Data Architects, and IT Leaders

    The progression to modern application stacks and microservices architectures has resulted in orders of magnitude more logs, metrics, events, and traces. Like gravity, data attracts more data, making it increasingly difficult to move and process as it accumulates over time. More than ever, there is a need to be able to stream-process, filter, mask, transform, aggregate, analyze, and route that data to various data tier destinations optimized for specific usage.
