Nomulus
Top-level domain name registry service on Google Cloud Platform
Nomulus is a production-grade, open-source domain registry platform used to operate top-level domains (TLDs). It implements the core registry protocols—EPP for registrar interactions, WHOIS/RDAP for public data access—and manages the lifecycle of domain objects, hosts, and contacts. The system is built to scale and to enforce policy: pricing rules, reserved names, premium tiers, grace periods, and automated renewals are modeled explicitly. It integrates with DNS provisioning, data escrow, and billing so you can run a compliant registry end-to-end rather than stitching together separate services. Operators get admin tools for reporting, manual adjustments, and policy configuration, while registrars interact through standards-compliant channels. Nomulus treats registries as serious infrastructure: audited flows, durable storage, and clear extension points for custom policies and TLD-specific behavior. -

Java JWT
Java implementation of JSON Web Token (JWT)
A Java implementation of JSON Web Token (JWT) - RFC 7519. This library requires Java 8 or higher. The last version that supported Java 7 was 3.11.0. The library implements JWT Verification and Signing using several algorithms. The Algorithm defines how a token is signed and verified. It can be instantiated with the raw value of the secret in the case of HMAC algorithms, or the key pairs or KeyProvider in the case of RSA and ECDSA algorithms. Once created, the instance is reusable for token signing and verification operations. When using RSA or ECDSA algorithms and you just need to sign JWTs you can avoid specifying a Public Key by passing a null value. The same can be done with the Private Key when you just need to verify JWTs. -

crawler4j
Open source web crawler for Java
crawler4j is an open source web crawler for Java which provides a simple interface for crawling the Web. Using it, you can setup a multi-threaded web crawler in few minutes. You need to create a crawler class that extends WebCrawler. This class decides which URLs should be crawled and handles the downloaded page. shouldVisit function decides whether the given URL should be crawled or not. In the above example, this example is not allowing .css, .js and media files and only allows pages within ics domain. visit function is called after the content of a URL is downloaded successfully. You can easily get the url, text, links, html, and unique id of the downloaded page. You should also implement a controller class which specifies the seeds of the crawl, the folder in which intermediate crawl data should be stored and the number of concurrent threads. -

Java library for access to Moodle's web services via the REST protocol (09/11/2013) Development of this project has been resurrected and the current code may be downloaded from https://github.com/bantonia/MoodleRest A compiled .jar will be available here once the code has been finalized. (30/03/2012 A newer version (V0.1.5) to work with Moodle 2.2 has been uploaded. Although still requires more documentation (better than it was) etc... Calls to create and update users now provides facilities to add preferences and customfields. Removed the batch calling of the web services (not needed as all calls are via POST and not GET), code is still there but commented out. V0.1.4 was removed, too many bugs! Previous versions using the Moodle 2.1 webservice calls are still here. Code for the next release which is under development can be downloaded from: https://github.com/bantonia/MoodleRest Note: The software is supplied as is under the GNU version 2.0 License.
