    OpenPatientOS

    OpenPatientOS

    OpenPatientOS is an information system for managing patient records

    It can support a small clinic or hospital in managing patient personal, medical, and billing records through an easy to use Swing user interface. How to install: i. Simply import the database dump from the database folder to create the necessary tables for the system to run. You can use either phpMyAdmin for localhost; Microsoft SQL Server; or simply Query Browser for MySQL. Other database environments have not been tested hence I don't guarantee their adaptability. ii. Run and Build the system in NetBeans IDE 7.0. Other IDEs have not been tested for this system. A more stable and installable version will be released soon. iii. Please rate the system and leave comments or reviews. iv. If you need any further clarification, post a question/query/doubt in the Wiki and I will reply ASAP. NB: Please use the "External Link" menus above to support this project in one way or another. PM me for other means. Any kind of support will be very much appreciated. Thanks a bunch.

    fileaxy

    fileaxy

    Fileaxy does file sync, de-duplication, image matching & bulk preview

    Fileaxy is a file de-duplication, organization, synchronization, and bulk previewing tool which utilizes a new user interface for local file management. Using content hashing or machine vision algorithms, Fileaxy can detect identical files as well as similar names, images, videos, or fonts and correlate those to others based on naming conventions. Optionally integrates with ImageMagick, GraphicsMagick, FFmpeg, and Mac Sips file decoding with a simple button click. Fileaxy opens NO network connections and will NOT request passwords. Fileaxy uses NO 3rd party libraries or code. Read/write wear to SSDs and mechanical drives is minimized where possible. Runs with Java 8+ [https://adoptopenjdk.net] on Mac, Windows, and Linux distros. My goal is to have Fileaxy manage 2 million available and unavailable files and their relationships live in the UI.
