The Art of Programming
A collection of practical tips can be found at the bottom of this page
The Art of Programming (Second Edition) is a curated collection of programming problems and solutions originally derived from the Microsoft 100 Interview Questions blog series, later refined into a long-running tutorial and ultimately a published book. Created by July, the series began in 2010 and has since evolved into an in-depth exploration of algorithmic thinking, data structures, and coding interview preparation. The repository brings together 42 classic programming problems from the original series, enhanced with detailed explanations, formula derivations, and optimized solutions. In July 2023, work on the second edition was announced, which expands the project with updated content, new problems inspired by recent big-tech interviews, and introductions to modern machine learning techniques such as XGBoost, CNNs, RNNs, and LSTMs. This collection serves both as a historical record of algorithm problem-solving and as a living resource for programmers preparing for interviews. -

TwelveMonkeys
Additional plug-ins and extensions for Java's ImageIO
TwelveMonkeys ImageIO provides extended image file format support for the Java platform, through plugins for the javax.imageio. package. The main goal of this project is to provide support for formats not covered by the JRE itself. Support for these formats is important, to be able to read data found "in the wild", as well as to maintain access to data in legacy formats. As there is lots of legacy data out there, we see the need for open implementations of readers for popular formats. -

ZXingLite
Simplified version of ZXing, optimized to scan codes to generate QR
ZXingLite for Android is a simplified and extremely fast version of ZXing. Based on the ZXing library, it optimizes the functions of scanning codes and generating QR codes/barcodes. The scanning interface fully supports customization, and one line of code can also use the default scanning function. In short, everything you want is here. By inheriting CaptureActivity or CaptureFragment and customizing the layout. (Applicable to most scenarios, and you don’t need to care about the code scanning related logic, you need to override the getLayoutId method when customizing the layout) Implementation examples: CustomCaptureActivity and QRCodeActivity. Instantiate a CameraScan in the Activity or Fragment of your project. (Applicable to use when you want to write interactive logic on the code scanning interface, and cannot directly or indirectly inherit CaptureActivity or CaptureFragment due to project architecture or other reasons) -

Zuul
Gateway service providing dynamic routing, monitoring and more
Zuul is an L7 application gateway that offers many capabilities, including dynamic routing, monitoring, security, resiliency and more. It is used in the backend of the Netflix streaming service as a front door for all requests from devices and web sites. Zuul is ideal for cases like this where API traffic volume and diversity can become overwhelming and cause production issues to arise suddenly and without warning. Zuul has a broad range of filters that enable it to perform multiple functions quickly and apply functionality to services like Netflix. These functions include security authentication, dynamic routing, stress testing, load shedding and more. -

fastjson
A fast JSON parser/generator for Java
Fastjson is a Java library that can be used to quickly convert Java Objects into their JSON representation or convert JSON strings to their equivalent Java object. Based on benchmarks it provides the best performance in both server side and Android client, and can work with arbitrary Java objects, even those pre-existing objects of which you do not have the source code. Fastjson provides a simple conversion method to turn Java objects to JSON and vice versa, with extensive support of Java Generics and arbitrarily complex objects. -

maven git commit id plugin
Maven plugin which includes build-time git repository information
git-commit-id-maven-plugin is a plugin quite similar to Build Number Maven Plugin for example but as the Build Number plugin at the time when I started this plugin only supported CVS and SVN, something had to be done. I had to quickly develop a Git version of such a plugin. For those who don't know the plugin, it basically helps you with the following tasks and answers related questions. The plugin is available from Maven Central (see here), so you don't have to configure any additional repositories to use this plugin. A detailed description of using the plugin is available in the Using the plugin document. All you need to do in the basic setup is to include that plugin definition in your pom.xml. For more advanced users we also prepared a guide to provide a brief overview of the more advanced configurations. Even though this plugin tries to be compatible with every Maven version there are some known limitations with specific versions. -
