KOOM creates a mobile high-performance online memory monitoring solution， which supplies a detailed report when OOM-related problems are detected and has solved a large number of OOM issues in the Kwai application. It's currently available on Android. With the increasing complexity of mobile terminal business logic and the gradual popularity of scenarios with high memory requirements such as 4K codec and AR magic watch, the OOM problem has become the number one problem in the stability management of the Kuaishou client. In the daily version iteration process, OOM surges occasionally occur, and the online environment is very complicated. There are thousands of AB experiments. Pre-prevention and post-recovery cannot be achieved. Therefore, high-performance online memory monitoring solutions are urgently needed.

LEA is a lightweight eyetracking algorithm library (hence the name) written in and for Java. LEA is able to track eye movements with an ordinary webcam and returns relative movements (up, down, ...). It is also able to compensate for slight head motions.

LGML is a GML parser under the LGPL license. The aim is to parse a GML document or fragment in order to get a WKT output. 2D and 3D inputs are both handled, but it is not permitted to have mixed geometries. The caller can choose if the input coordinates are parsed as X, Y, Z (if present) order, or Y, X, Z (if present) order. The willing of the project is to be a starting point useful for developers that need to parse GML objects in order to use them, for example, in the context of OGC catalogue projects. The library is compiled using Java 1.5 or 1.6. For now, supported inputs are: LineString, MultiLineString, MultiPoint, MultiPolygon, Point, Polygon, MultiSurface (in an experimental way: the only child object handled is Polygon). At the following URL: http://95.110.227.201:8080/lgml is exposed a minimal web interface in order to test it.

LIEL (Language Independent Extension Library) is a language-agnostic library containing solutions to various programming problems and extending the capabilities of existing frameworks and code libraries.

LWKT is a WKT parser under the LGPL license. It have not dependencies: it is pure Java compiled with 1.5 or 1.6 version. The output can be as GML 2 or 3 version, optionally setting a SRS name. Supported inputs are: POINT, MULTIPOINT, LINESTRING, MULTILINESTRING, POLYGON, MULTIPOLYGON For each of them, are handled both 2D inputs like: POINT(2.4 12.66) and 3D inputs like: POINT Z(2.4 12.66 0.0) At the following URL: http://95.110.227.201:8080/lwkt is exposed a minimal web interface in order to test it. To do: -add the possibility to parse the input as XY(Z) or YX(Z)

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.

Laverca is an open-source Java API for requesting signatures using mobile signature services. Mobile signature service (MSS) allows users to sign messages securely using mobile devices. For instance, Laverca API can be used for document signing or strong user authentication in a login system. Laverca implements the ETSI TS 102 204 SOAP interface for application providers (APs). It means that Laverca can communicate with ETSI 204 conforming MSS systems. Laverca supports synchronous and asynchronous signature requests. Status of an asynchronous signature request can be polled. In addition to the ETSI features, Laverca includes the FiCom 2.0 features specified in Finland.

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/.

LibRec is a Java library for recommender systems (Java version 1.7 or higher required). It implements a suit of state-of-the-art recommendation algorithms, aiming to resolve two classic recommendation tasks: rating prediction and item ranking.

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“.

Java implementation of MIKEY (Multimedia Internet KEYing, RFC 3830).

This project provides free (even for commercial use) state-of-the-art information extraction tools. The current release includes tools for performing named entity extraction and binary relation detection as well as tools for training custom extractors and relation detectors. MITIE is built on top of dlib, a high-performance machine-learning library[1], MITIE makes use of several state-of-the-art techniques including the use of distributional word embeddings[2] and Structural Support Vector Machines[3]. MITIE offers several pre-trained models providing varying levels of support for both English, Spanish, and German trained using a variety of linguistic resources (e.g., CoNLL 2003, ACE, Wikipedia, Freebase, and Gigaword). The core MITIE software is written in C++, but bindings for several other software languages including Python, R, Java, C, and MATLAB allow a user to quickly integrate MITIE into his/her own applications.
