HStreamDB is an open-source, cloud-native streaming database for IoT and beyond. Modernize your data stack for real-time applications. By subscribing to streams in HStreamDB, any update of the data stream will be pushed to your apps in real-time, and this promotes your apps to be more responsive. You can also replace message brokers with HStreamDB and everything you do with message brokers can be done better with HStreamDB. HStreamDB provides built-in support for event time-based stream processing. You can use your familiar SQL to perform basic filtering and transformation operations, statistics and aggregation based on multiple kinds of time windows and even joining between multiple streams. With connectors provided, you can easily integrate HStreamDB with other external systems, such as MQTT Broker, MySQL, Redis and ElasticSearch. More connectors will be added.

Command-line Kanban board/task manager with support for Trello boards and GitHub projects. A CLI kanban board/task manager for Mac and Linux. Per project task lists, vim style key-bindings, stored using Markdown. Clean diffs for easy version control, support for sub-tasks and due dates, Trello board imports, and GitHub project imports. If you’re using a simple two-column “To Do” and “Done” then use the space bar to mark an item as complete while staying in the “To Do” list. If you’re using a more complicated column setup then you will want to use H/L to move tasks between columns. By default times are stored in the Markdown file as UTC. If you would like local times (and are unlikely to open the file in lots of different timezones) then you can set localTimes to true in the markdown section of the config file.
