Swagger2Markup
Swagger to AsciiDoc or Markdown converter
The primary goal of this project is to simplify the generation of up-to-date RESTful API documentation by combining documentation that’s been hand-written with auto-generated API documentation produced by Swagger. The result is intended to be an up-to-date, easy-to-read, on- and offline user guide, comparable to GitHub’s API documentation. The output of Swagger2Markup can be used as an alternative to swagger-UI and can be served as static content. Swagger2Markup converts a Swagger JSON or YAML file into several AsciiDoc or GitHub Flavored Markdown documents which can be combined with hand-written documentation. The Swagger source file can be located locally or remotely via HTTP. Swagger2Markup supports the Swagger 1.2 and 2.0 specifications. Internally it uses the official swagger-parser and my markup-document-builder. You can use Swagger2Markup to convert your contract-first Swagger YAML file into a human-readable format. -

SwipeRecyclerView
RecyclerView slide menu, Item drag, slide to delete Item
SwipeRecyclerView is an Android library that extends the familiar RecyclerView API with common interactive list behaviors. It adds configurable left and right swipe menus whose items can be arranged horizontally or vertically. Rows can also be deleted by swiping or reordered through long-press dragging. Developers can add and remove header and footer views without replacing their normal adapter workflow. The component supports automatic or tap-triggered loading of additional data. Hierarchical lists can use linear, grid, or staggered layouts, and sticky views can remain visible during scrolling. Separate artifacts support the older Android support library and AndroidX environments. -

Takes
True object-oriented Java web framework without NULLs
Takes is a true object-oriented and immutable Java8 web development framework. Pay attention that UTF-8 encoding is set on the command line. The entire framework relies on your default Java encoding, which is not necessarily UTF-8 by default. To be sure, always set it on the command line with file.encoding Java argument. We decided not to hard-code "UTF-8" in our code mostly because this would be against the entire idea of Java localization, according to which a user always should have a choice of encoding and language selection. We're using Charset.defaultCharset() everywhere in the code. Essential part of Bigger Example is Front interface. It's encapsulates server's back-end and used to start an instance, which will accept requests and return results. FtBasic, which is a basic front, implements that interface. -

TapTargetView
An implementation of tap targets from the Material Design guidelines
An implementation of tap targets from Google's Material Design guidelines on feature discovery. Prompt users to try features or functionality that can be completed in a single tap, such as saving a location in a map app. Prompt users to try features or functionality that require more than one tap to complete, such as turning on automatic backup in a photo app. Feature discovery prompts have more impact when they are presented to the right users at contextually relevant moments. When presented to the wrong user at the wrong time, they can be intrusive and annoying. A user’s interaction with a message signals their satisfaction with it and informs when to show the next message. Feature discovery scenarios and app UIs have specific material design components. A feature discovery prompt focuses user attention on a specific UI element. It contains a tap target, indicated by a circular shape, which is surrounded by a larger area with a distinct background color. -

Termin-Bot
Telegram bot to get notifications about free appointments
Termin (eng. appointment) is essential in Germany, especially in Berlin. Sometimes it is tough to get a termin in public institutions and this bot is a way to automate termin checks and send Telegram notifications, if free termin was found. The code could be also considered as a template for subsequent development. The principle of bot operation is to refresh a webpage with needed appointments periodically [TERMIN_URL] and to recognize the change on it. E.g., the page always contains the phrase "No free appointments" [NO_TERMIN_FOUND_STRING]. Then some free appointments are added to the system, and the phrase "No free appointments" disappears. There is a new phrase (e.g., "List of free appointments" [TERMIN_FOUND_STRING]) instead of the old one. Bot recognizes the change on the webpage and sends Telegram notifications about free appointments. -

The Ballerina programming language
The Ballerina Programming Language
Ballerina is an open-source programming language for the cloud that makes it easier to use, combine, and create network services. Network primitives in the language make it simpler to write services and run them in the cloud. Structural types with support for openness are used both for static typing within a program and for describing service interfaces. Type-safe, declarative processing of JSON, XML, and tabular data with language-integrated queries. Explicit error handling, static types, and concurrency safety, combined with a familiar, readable syntax make programs reliable and maintainable. Easy and efficient concurrency with sequence diagrams and language-managed threads without the complexity of asynchronous functions. Programs have both a textual syntax and an equivalent graphical form based on sequence diagrams. -

Transmittable ThreadLocal
Provides an enhanced InheritableThreadLocal
TransmittableThreadLocal (TTL), the missing Java™ std lib(simple & 0-dependency) for framework/middleware, provide an enhanced InheritableThreadLocal that transmits values between threads even using thread pooling components. In the case of using thread pools and other execution components that will pool multiple threads, the ThreadLocalvalue transfer function is provided to solve the problem of context transfer during asynchronous execution. A Javastandard library should provide standard capabilities for framework/middleware facility development. ThreadLocalThe demand scenario is TransmittableThreadLocalthe potential demand scenario. If your business needs to "pass ThreadLocalvalues in the case of using thread pools and other execution components that will pool multiple threads ", it is the TransmittableThreadLocaltarget scenario. -

Tsunami
Network security scanner for detecting severity vulnerabilities
Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence. When security vulnerabilities or misconfigurations are actively exploited by attackers, organizations need to react quickly in order to protect potentially vulnerable assets. As attackers increasingly invest in automation, the time window to react to a newly released, high severity vulnerability is usually measured in hours. This poses a significant challenge for large organizations with thousands or even millions of internet-connected systems. In such hyperscale environments, security vulnerabilities must be detected and ideally remediated in a fully automated fashion. To do so, information security teams need to have the ability to implement and roll out detectors for novel security issues at scale in a very short amount of time. Furthermore, it is important that the detection quality is consistently very high. -

Webcam Capture API
Allow integrated or USB-connected webcams to be accessed from Java
This library allows you to use your built-in or external webcam directly from Java. It's designed to abstract commonly used camera features and support various capturing frameworks. Assume a situation when your code depends on some capturing framework, but suddenly you have to drop it and use a different, maybe newer one (e.g. replace archaic JMF with newest GStreamer). By doing this you will have to rewrite significant piece of your code because these frameworks are completely different and not compatible at all. This is where Webcam Capture API comes to save the world - it was created to remove the burden of such situations so you do not have to rewrite your code ever again, but instead, you can simply switch the driver class to a different one. -
