PetriNetExec: Java Embeddable Petri Nets
PetriNetExec a library for embedding Petri Nets into Java applications
Briefly said, PetriNetExec is an open-source Java library which allows you to embed Petri Nets into your Java application. Using PetriNetExec you can define places and transitions, connect them using arcs and inhibitors, define the initial marking and then fire events and see how tokens flow into the network. * PetriNetExec does not provide a GUI for editing the network nor will it provide in the near future. That is not really a feature :-) but to those of you able to cope with this news I suggest to read further; * Petri Nets are created with PetriNetExec by writing Java code and using the provided API; * PetriNetExec provides a simple yet powerful callback mechanism allowing you to actually do something when events are fired and the network status is changing. * PetriNetExec is embeddable into your Java application. This means that you can build your own application and add Petri Nets into it. * PetriNetExec is open-source. -

Picasso
A powerful image downloading and caching library for Android
Images add much-needed context and visual flair to Android applications. Picasso allows for hassle-free image loading in your application—often in one line of code! Many common pitfalls of image loading on Android are handled automatically by Picasso: Handling ImageView recycling and download cancelation in an adapter. Complex image transformations with minimal memory use. Automatic memory and disk caching. Adapter re-use is automatically detected and the previous download canceled. Transform images to better fit into layouts and to reduce memory size. You can also specify custom transformations for more advanced effects. Picasso supports both download and error placeholders as optional features. Resources, assets, files, content providers are all supported as image sources. For development you can enable the display of a colored ribbon which indicates the image source. -

PieceOCake
A ridiculously simple Java save/load library
Do you ever curse Java for making it so ridiculously difficult just to save and load data? Do you ever say something like the following: "All I want to do is save the user's data! I don't want to deal with your BufferedWriters and HashMapThingies and stuff!" ...all in a remarkably incensed tone? Well, DON'T! There's a solution! It's a PIECE O' CAKE! Just use this handy dandy library and you can save/load like a champ. Forget about said BufferedWriters and HashMapThingies. What's so cakeriffic about this library: -Can store Strings, ints, and String arrays faithfully -Can completely ignore what goes on behind the scenes -Save() and load() methods to get your data. That's it. -So easy a subpar baker could use it How do you use it? Easy. -Tell PieceOCake what data you want to store. -Call the load() function. -Use get() and set() to, well, get and save your data. That's it. It's a Piece O Cake! -

Piranha
A tool for refactoring code related to feature flag APIs
Feature flags are commonly used to enable gradual rollout or experiment with new features. In a few cases, even after the purpose of the flag is accomplished, the code pertaining to the feature flag is not removed. We refer to such flags as stale flags. The presence of code pertaining to stale flags can have the following drawbacks. Unnecessary code clutter increases the overall complexity w.r.t maintenance resulting in reduced developer productivity The flags can interfere with other experimental flags (e.g., due to nesting under a flag that is always false) Presence of unused code in the source as well as the binary. Stale flags can also cause bugs. Piranha is a tool to automatically refactor code related to stale flags. At a higher level, the input to the tool is the name of the flag and the expected behavior, after specifying a list of APIs related to flags in a properties file. -

PlaceHolderView
This library provides advance views for lists and stacks
PlaceHolderView is an Android library for building advanced lists, expandable collections, infinite feeds, and swipeable card stacks. Some components extend RecyclerView, while others use independent implementations tailored to gesture-driven interfaces. Its annotation-based API reduces adapter and binding boilerplate by generating binding classes during compilation. PlaceHolderView offers a standard list container, an infinite-scrolling variant, and a parent-child expandable view. SwipePlaceHolderView supports Tinder-style card stacks, while SwipeDirectionalView reports swipe directions and touch events. The library includes Java and Kotlin integration paths, although its dependencies and support-library examples reflect an older Android ecosystem. -
