A simple time-tracker program for GNOME. Instead of using online-first options like Toggl and Clockify, use a lightning-fast local-first option that is still able to sync with multiple computers via cloud or network storage.
      Time Tracker allows you to track different projects, see how much time you've spent on each project, and sync with a local file or a file in your own cloud storage. You can also open your sync file in spreadsheet software (since it's a CSV file).

SimpleX - the first messaging platform that has no user identifiers, not even random numbers!
      Security assessment was done by Trail of Bits in November 2022.
      SimpleX Chat features:
      
        end-to-end encrypted messages, with editing, replies and deletion of messages.
        sending end-to-end encrypted images and files.
        single-use and long-term user addresses.
        secret chat groups - only group members know it exists and who is the member.
        end-to-end encrypted audio and video calls.
        private instant notifications.
        portable chat profile - you can transfer your chat contacts and history to another device (terminal or mobile).
      
      SimpleX Chat advantages:
      
        Full privacy of your identity, profile, contacts and metadata: unlike any other existing messaging platform, SimpleX uses no phone numbers or any other identifiers assigned to the users - not even random numbers. This protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers.
        Complete protection against spam and abuse: as you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address.
        Full ownership, control and security of your data: SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received.
        Decentralized network: you can use SimpleX with your own servers and still communicate with people using the servers that are pre-configured in the apps or any other SimpleX servers.
      
      You can connect to anybody you know via link or scan QR code (in the video call or in person) and start sending messages instantly - no emails, phone numbers or passwords needed.
      Your profile and contacts are only stored in the app on your device - our servers do not have access to this information.
      All messages are end-to-end encrypted using open-source double-ratchet protocol; the messages are routed via our servers using open-source SimpleX Messaging Protocol.

The REV Hub Interface is a piece of software allowing for a direct connection from a REV Expansion Hub and its peripherals to a PC.
      This interface provides a method for teams to prototype with motors, servos, and sensors in a way that is faster and easier than setting up an entire robot control system. It is also a valuable troubleshooting tool that can help isolate the cause of an issue and determine if it is electrical or software related. The REV Hub Firmware can also be updated and recovered through this interface in addition to the Robot Controller Application. 
      This is a community continuation of the software, updating to newer underlying technologies (e.g. porting from Python 2 to Python 3), adding features, and porting to more platforms (Linux and macOS, in addition to Windows). Though initially created by REV, this version of the software is not maintained by or affiliated with REV. Do not contact REV support about any issues you experience with this software.
