PRTG Catches Network Issues Before They Cause Downtime
Threshold-based alerts flag problems early, so your team can act before users notice, not after.
Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

A suite of RPN calculators and a class library for Object Pascal
TRURL is a suite of desktop calculators with reverse Polish notation (RPN) written in Object Pascal. Additionally, it comes with a free reusable class library (RPN Engine) as a toolbox for creating your own calculator.
TRURL is an acronym for "TRURL is a Reusable Universal RPN Library".
Class Libraries:
• RPN Engine: Full-featured calculation engine for Pascal-based RPN calculators
• Segmitator: Library for virtual seven-segment displays

Imaging is native Object Pascal (Delphi and FPC) image loading, saving and manipulation library. It is available for several platforms and does not require any third party dynamic libraries.
...MuPDF is maybe one of the best options, but is stuck on version 1.08 (from 2015), to be used with Lazarus.
I managed to bring the supported version up to 1.17.0 (latest MuPDF). Only for Win64. Help is welcome to bring support for MacOS, Linux and Haiku.
As I have no previous experience using external libraries and writing headers for them, I can use some help. So if you want the newest version of MuPDFLib support, please give me a hand.
A framework library which aims to independize we all, the delphi developers, from the different glitches of the platform, and attempts to provide code that is independent from the OS. It is based on *heavy* use of interfaces. Works on FPC (FreePascal).
