SMS Backup+
Backup Android SMS, MMS and call log to Gmail / Gcal / IMAP
This is a fork of the now-defunct Android backup tool SMS Backup. It uses Gmail/IMAP to perform SMS, MMS and call log backups over the network. It is important that you perform the first backup manually. SMS Backup+ needs to know whether you want to upload messages currently stored on your device or not. SMS Backup+ can also backup and restore your call logs. It stores all calls using a separate label (defaults to Call log, but can be changed in "Advanced settings"). If you wish you can set this to the same value as SMS, to make all backups use the same label. -

FadCam
Open-source, ad-free Android multimedia recorder with background video
FadCam is an open-source Android multimedia recorder designed around privacy, customization, and ethical use. It started as a seamless background video recorder, but its scope now includes dashcam-style recording, screen recording, live streaming over local networks, and remote camera control. The app is ad-free and built for users who want practical recording tools without relying on commercial surveillance-style apps. It provides options for video quality, watermarks, internal storage, gallery saving, and playback inside the app. Its cloud and remote-control capabilities make it useful for legitimate workflows such as personal safety, travel recording, device monitoring with consent, and local media capture. Because the project can record in sensitive contexts, its responsible-use framing is an important part of its identity. -

JUnit 4
A programmer-oriented testing framework for Java
JUnit is a simple framework to write repeatable tests. It is an instance of the xUnit architecture for unit testing frameworks. You need to have a JDK installed and a text editor. (In general it is recommended to use a build tool for building your software and running the tests.). JUnit features include assertions for testing expected results, test fixtures for sharing common test data, test runners for running tests. JUnit was originally written by Erich Gamma and Kent Beck. JUnit is Open Source Software, released under the Eclipse Public License Version 1.0. JUnit celebrates programmers testing their own software. In this spirit, bugs, patches, and feature requests that include JUnit tests have a better chance of being addressed than those without. -

LWJGL
Java library that enables cross-platform access to popular native APIs
LWJGL is a Java library that enables cross-platform access to popular native APIs useful in the development of graphics (OpenGL, Vulkan), audio (OpenAL) and parallel computing (OpenCL) applications. This access is direct and high-performance, yet also wrapped in a type-safe and user-friendly layer, appropriate for the Java ecosystem. LWJGL is an enabling technology and provides low-level access. It is not a framework and does not provide higher-level utilities than what the native libraries expose. As such, novice programmers are encouraged to try one of the frameworks or game engines that make use of LWJGL, before working directly with the library. -

Spring Initializr
A quickstart generator for Spring projects
A quickstart generator for Spring projects. The various options for the projects are expressed in a metadata model that allows you to configure the list of dependencies, supported JVM and platform versions, etc. Spring Initializr also exposes web endpoints to generate an actual project and also serve its metadata in a well-known format to allow third-party clients to provide the necessary assistance. A set of optional conventions for Spring Boot projects is provided and are used in our production instance at https://start.spring.io. To better understand how our service is configured, you may want to check the companion project and, in particular, the configuration of our instance. Such configuration is also described in details in the documentation. -

Strimzi
Apache Kafka® running on Kubernetes
Strimzi provides a way to run an Apache Kafka cluster on Kubernetes in various deployment configurations. Strimzi provides a way to run an Apache Kafka cluster on Kubernetes in various deployment configurations. For development, it’s easy to set up a cluster in Minikube in a few minutes. For production you can tailor the cluster to your needs, using features such as rack awareness to spread brokers across availability zones, and Kubernetes taints and tolerations to run Kafka on dedicated nodes. You can expose Kafka outside Kubernetes using NodePort, Load balancer, Ingress and OpenShift Routes, depending on your needs, and these are easily secured using TLS. The Kube-native management of Kafka is not limited to the broker. You can also manage Kafka topics, users, Kafka MirrorMaker and Kafka Connect using Custom Resources. This means you can use your familiar Kubernetes processes and tooling to manage complete Kafka applications. -

Zipkin
Distributed tracing system to gather timing data
Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data. If you have a trace ID in a log file, you can jump directly to it. Otherwise, you can query based on attributes such as service, operation name, tags and duration. Some interesting data will be summarized for you, such as the percentage of time spent in a service, and whether or not operations failed. The Zipkin UI also presents a Dependency diagram showing how many traced requests went through each application. This can be helpful for identifying aggregate behavior including error paths or calls to deprecated services. Applications need to be “instrumented” to report trace data to Zipkin. -
