PRTG Catches Network Issues Before They Cause DowntimeReactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

Lagom
Reactive Microservices for the JVM
The opinionated microservices framework for moving away from the monolith. Lagom helps you decompose your legacy monolith and build, test, and deploy entire systems of Reactive microservices. Lagom is an open source framework for building systems of Reactive microservices in Java or Scala. Lagom builds on Akka and Play, proven technologies that are in production in some of the most demanding applications today. Lagom's integrated development environment allows you to focus on solving business problems instead of wiring services together. A single command builds the project, starts supporting components and your microservices, as well as the Lagom infrastructure. The build hot-reloads when it detects changes to source code. -

Last Java Collection Library
Java library to work with scalar arrays as usual Collections
The package allows to work with scalar arrays as usual collections. The problem with a scalar array Java templates don't support scalar types as generic parameters. Java code working with collection interfaces such as List or Collection is inapplicable for arrays. Some libraries supply methods to work with object array. These methods are generic and built-in types int, boolean, long, short, byte, double, float suffer. The number of scalar type is small and finite. There are realization of Iterable, Iterator, Collection, and List interfaces for each scalar type. Also the library gives such useful methods as contains and indexOf for objects with Iterable interface only. Yeah. There is some stupidness because all implementations differ between each other only types and this code has 100% implicit coupling and duplications. But Java has not left other way. -

Let
Annotation based API flavored with AOP to handle Android models
Annotation-based simple API flavored with AOP to handle new Android runtime permission model. If you check Google's Samples about the new permission model, you'll see a lot of boilerplate code for requesting, handling, and retrying the request for required permissions. Let will minimize the boilerplate code you have to write for requesting and handling permissions and hence help you keep your code more readable. Let will check these annotated methods and execute them unless the permissions required are granted; otherwise, Let will put on hold the method execution on and request these permissions at runtime. After examining the permission request result, Let will execute the method already put on hold only if the permissions are granted by user. -

LibBWEntrainment
Extensible Brainwave Entrainment library for Java
LibBWEntrainment is a Free and Open Source Brainwave Entrainment Library for Java. *** It is not a standalone application. *** The library is very flexible, allowing different types of renderers (isochronic, binaural, ...) as well as multiple output devices (speakers, file, socket or even screen), and it can easily be ported to other languages because it doesn't use any proprietary Java feature. Current features: -Javadoc and examples -Extremely lightweight, yet flexible -Easy to use -XML Presets -Multiple Entrainment Tracks -Looping -Isochronic rendering -Output to PC and Android -Output to MP3/FLAC/Wav file -Output to raw Stream Compared to my old LibBinaural, this is twice as fast and much more flexible. A project using this library is available here https://sourceforge.net/projects/isochronic/. -

LitePal for Android
Android library that makes developers use SQLite database
LitePal is an open-source Android library designed to simplify working with SQLite databases. It uses an object-relational mapping approach so developers can perform most database operations without writing SQL. Models can be mapped directly to database tables with minimal configuration. The library automatically handles table creation, alteration, and deletion as application models evolve. It provides APIs for saving, updating, deleting, querying, aggregate operations, and transactions. LitePal also supports multiple databases, fluent queries, Java and Kotlin development, and direct SQL when greater control is required. -

Lnkdlst
Single sided linked list (kind of lib with test-code, C, C++ and java)
Use own (user) data section for each Linked-List-Element (LLEl) including a fix Identifier which is for search via basic Lnkdlst function (fast ID-part-search, e.g. to find all elements with a specific bit in the ID set). Main list-linkage-change functions: append, insert, delete. - Examples: use of flexible variable ArgList (OnePointerArg, optional valid if not NULL, Argument-Type by ID-Number is easy to get), key-value pairs, build FIFO{queue}/LIFO{stack}, auto-list with max. Element-Size and chronological order. Use malloc{slower-but-easy} or fix (static) memory. - OAList01: Object-Kind of a predefined pre-reserved List with X Elements (with constant user-data size), with secur modify functions and option to use locks (POSIX: mutex). Supporting a BusyList and a IdleList for easy build of e.g. a FIFO without need of much time for mem-allocation. - Release-Notes see uws-Lnkdlst-readme.txt in the tar.gz file(s) and in „Files“. -

Logbook
An extensible Java library for HTTP request and response logging
Logbook is an extensible Java library to enable complete request and response logging for different client- and server-side technologies. It satisfies a special need by a) allowing web application developers to log any HTTP traffic that an application receives or sends b) in a way that makes it easy to persist and analyze it later. This can be useful for traditional log analysis, meeting audit requirements or investigating individual historic traffic issues. Logbook is ready to use out of the box for most common setups. Even for uncommon applications and technologies, it should be simple to implement the necessary interfaces to connect a library/framework/etc. to it. -
