Ormolu - formatter for Haskell source code - LinuxLinks
Ormolu is a formatter for Haskell source code. The project was created with the following goals in mind:
Using GHC’s own parser to avoid parsing problems caused by haskell-src-exts. Let some whitespace be programmable. The layout of the input influences the layout choices in the output. This means that the choices between single-line/multi-line layouts in certain situations are made by the user, not by an algorithm. This makes the implementation simpler and leaves some control to the user while still guaranteeing that the formatted code is stylistically consistent. Writing code in such a way so it’s easy to modify and maintain. Implementing one “true” formatting style which admits no configuration. The formatting style aims to result in minimal diffs. Choose a style compatible with modern dialects of Haskell. As new Haskell extensions enter broad use, we may change the style to accommodate them. Idempotence: formatting already formatted code doesn’t change it. Be well-tested and robust so that the formatter can be used in large projects.

Gaphor - simple UML and SysML modeling tool - LinuxLinks
Gaphor is a UML, SysML, RAAML, and C4 modeling application. It is designed to be easy to use, while still being powerful. Gaphor implements a fully-compliant UML 2 data model, so it is much more than a picture drawing tool. You can use Gaphor to quickly visualize different aspects of a system as well as create complete, highly complex models.
Gaphor provides four modeling languages: UML, SysML, RAAML and C4 and makes them accessible to beginners.
Gaphor is designed around the following principles:
Simplicity: The application should be easy to use. Only some basic knowledge of UML or SysML is required. Consistency: UML is a graphical modeling language, so all modeling is done in a diagram. Workability: The application should not bother the user every time they do something non-UML-ish.
