    fd

    fd

    A simple, fast and user-friendly alternative to 'find'

    ...While it does not aim to support all of find's powerful functionality, it provides sensible (opinionated) defaults for a majority of use cases. First, to get an overview of all available command line options, you can either run fd -h for a concise help message or fd --help for a more detailed version. fd is designed to find entries in your filesystem. The most basic search you can perform is to run fd with a single argument: the search pattern. Instead of just showing the search results, you often want to do something with them. fd provides two ways to execute external commands for each of your search results: the -x/--exec option runs an external command for each of the search results (in parallel), or the -X/--exec-batch option launches the external command once, with all search results as arguments.

OpenRPA also includes other features within itself, such as Image detection/OCR, Browser Navigation and many others. The installer first prompts the user whether OpenRPA should be installed only for the specific single user or universally (all users). It is recommended to install it universally (requires administrator previleges), as it have no downsides, so unless something (or someone) prohibits you from installing it for all users, always do it so. ...

    eBus

    Publish/Subscribe, Request/Reply Messaging API for Java.

    A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.

    PingMe is a personal project to satisfy my needs of having alerts, most major platforms have integration to send alerts but its not always useful, either you are stuck with one particular platform, or you have to do alot of integrations. I needed a small app which i can just call from my backup scripts, cron jobs, CI/CD pipelines or from anywhere to send a message with particular information. And i can ship it everywhere with ease. Hence, the birth of PingMe. Everything is configurable via environment variables, and you can simply export the logs or messages to a variable which will be sent as message, and most of all this serves as a swiss army knife sort of tool which supports multiple platforms. ...

    dzBdsLauncher

    smart launcher that automatically selects the correct BDS version

    ...While .dproj files can be opened with newer versions of Delphi than the one that created them, it does not work the other way around. So if you open a Delphi 10 .dproj file with e.g. Delphi 2007, you will just get an error message. If you open a Delphi 2007 .dproj file with Delphi 10, it will automatically convert it to the new format used by that version and it will be unreadable by Delphi 2007. The idea is to register dzBdsLauncher as the handler for .dpr, .dproj, .bdsproj, .dof and .groupproj files in Windows, so your chances of opening the right version of Delphi when double clicking on such a file will be much higher than normal.
