ANTLR
Parser generator to read, process, or translate structured text
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees. It’s widely used in academia and industry to build all sorts of languages, tools, and frameworks. Twitter search uses ANTLR for query parsing, with over 2 billion queries a day. The languages for Hive and Pig, the data warehouse and analysis systems for Hadoop, both use ANTLR. Lex Machina uses ANTLR for information extraction from legal texts. Oracle uses ANTLR within SQL Developer IDE and their migration tools. NetBeans IDE parses C++ with ANTLR. The HQL language in the Hibernate object-relational mapping framework is built with ANTLR. -

AWS X-Ray SDK for Java
The official AWS X-Ray Recorder SDK for Java
AWS X-Ray recommends using AWS Distro for OpenTelemetry (ADOT) to instrument your application instead of this X-Ray SDK due to its wider range of features and instrumentations. The AWS X-Ray SDK for Java is compatible with Java 8 and 11. Applications may make downstream HTTP calls to communicate with other applications. If these downstream applications are also traced, trace context information will need to be passed so that the trace segments may be properly grouped into a single trace. It may be useful to further decorate portions of an application for which performance is critical. Generating subsegments around these hot spots will help in understanding their impact on application performance. There are a few different styles available for tracing custom methods.You can automatically inject your current Trace ID into logging statements if you use the Log4J or SLF4J logging frontends. -

Aleph
Asynchronous streaming communication for Clojure
Aleph is an asynchronous I/O framework for Clojure built atop Netty, offering efficient, non-blocking network programming with support for HTTP, raw TCP/UDP, and streaming through Manifold streams. Aleph follows the Ring spec fully and can be a drop-in replacement for any existing Ring-compliant server. However, it also allows for the handler function to return a Manifold deferred to represent an eventual response. This feature may not play nicely with synchronous Ring middleware, which modifies the response, but this can be easily fixed by reimplementing the middleware using Manifold's let-flow operator. The aleph.http/wrap-ring-async-handler helper can be used to convert async 3-arity Ring handler to an Aleph-compliant one. -

Azure SDK for Java
Active development of the Azure SDK for Java
This repository is for the active development of the Azure SDK for Java. For consumers of the SDK we recommend visiting our public developer docs or our versioned developer docs. To get started with a specific service library, see the README.md file located in the library's project folder. You can find service libraries in the /SDK directory. For a list of all the services, we support to access to our list of all existing libraries. New wave of packages that follow the Azure SDK Design Guidelines for Java and share a number of core features such as HTTP retries, logging, transport protocols, authentication protocols, etc., so that once you learn how to use these features in one client library, you will know how to use them in other client libraries. These libraries can be easily identified by folder, package, and namespaces names starting with azure-, e.g. azure-key vault. -

Conscrypt
Conscrypt is a Java Security Provider
Conscrypt is a modern TLS/SSL provider for Java that replaces the default JCE/JCA crypto stack with one backed by BoringSSL for better performance and security posture. It is implemented as a drop-in SecurityProvider, so applications and frameworks can opt in without changing high-level HTTPS or socket code. The provider focuses on contemporary protocol hygiene—up-to-date cipher suite selection, ALPN, session resumption, and hardened defaults—so Java servers and clients negotiate secure connections by construction. Because it builds on BoringSSL’s audited primitives and constant-time implementations, it reduces the risk of subtle side-channel issues while improving handshake and bulk crypto throughput. Conscrypt also exposes platform accelerations (like AES-GCM and ChaCha20-Poly1305) and supports features important to HTTP/2 and HTTP/3 stacks. Its goal is pragmatic: deliver a fast, well-maintained TLS provider that behaves like modern browsers and mobile stacks. -

DNS-Based Host Blocking for Android
DNS-based Host Blocker (and lightweight ad blocker) for Android
This is a DNS-based host blocker for Android. In the default configuration, several widely-respected host files are used to block ads, malware, and other weird stuff. On the first start, you must manually update the hosts files (using the refresh button) before the service can work correctly (issue #1); and you must also update the hosts files yourself regularly for now. Items in the hosts and DNS servers lists can be moved around and removed) of the list using standard RecyclerView interactions (long press makes the entry movable, swipe to either side removes it). For hosts, a later entry overrides a previous entry; for DNS servers, the first server is preferred. There's also no validation of input, so DNS servers that are not valid IPv4 addresses are not rejected, neither are URLs for DNS server entries (we intend to support URLs in the future, so you can point the app to a remote list of servers). -

Datahike
A durable Datalog implementation adaptable for distribution
Datahike is a durable Datalog database powered by an efficient Datalog query engine. This project started as a port of DataScript to the hitchhiker-tree. All DataScript tests are passing, but we are still working on the internals. Having said this we consider Datahike usable for medium sized projects, since DataScript is very mature and deployed in many applications and the hitchhiker-tree implementation is heavily tested through generative testing. We are building on the two projects and the storage backends for the hitchhiker-tree through konserve. We would like to hear experience reports and are happy if you join us. We provide a small stable API for the JVM at the moment, but the on-disk schema is not fixed yet. We will provide a migration guide until we have reached a stable on-disk schema. Take a look at the ChangeLog before upgrading. -

Fresco
An Android library for managing images and the memory they use
Fresco’s image pipeline will load images from the network, local storage, or local resources. To save data and CPU, it has three levels of cache; two in memory and another in internal storage. Fresco’s Drawee shows a placeholder for you until the image has loaded and then automatically shows the image when it arrives. When the image goes off-screen, it automatically releases its memory. A decompressed image - an Android Bitmap - takes up a lot of memory. This leads to more frequent runs of the Java garbage collector. This slows apps down. The problem is especially bad without the improvements to the garbage collector made in Android 5.0. On Android 4.x and lower, Fresco puts images in a special region of Android memory. It also makes sure that images are automatically released from memory when they’re no longer shown on screen. This lets your application run faster - and suffer fewer crashes. -

Google Authenticator OpenSource
Open source version of Google Authenticator (except the Android app)
Google Authenticator is the open-source counterpart of Google’s one-time passcode apps, implementing industry-standard OATH algorithms such as TOTP (time-based) and HOTP (counter-based) for two-factor authentication. The repository historically hosts code for mobile platforms like iOS and BlackBerry, demonstrating how to generate numeric codes locally without needing network access. Its core purpose is to help services and users add a second factor that’s simple to deploy yet resistant to password reuse and phishing. The app flow revolves around enrolling secrets via QR codes or manual entry, storing them securely on-device, and rendering rotating codes synchronized by time. Because it uses open standards, it interoperates with virtually any service that supports TOTP/HOTP, not just Google properties. The project also serves as a reference for implementers who want to understand enrollment UX, secret provisioning, and code generation at the application layer. -
