Interviews is an open source repository designed as a comprehensive guide to preparing for technical interviews, with a strong focus on computer science fundamentals and algorithmic problem solving. Created by Kevin Naughton Jr., the project compiles detailed notes, explanations, and code implementations that cover core areas tested in software engineering interviews. The repository emphasizes topics such as data structures, algorithms, system design, operating systems, databases, and networking. It also includes practical coding examples and solutions that demonstrate how to approach and solve common problems asked at companies like Google, Amazon, Facebook, and Microsoft. By consolidating essential knowledge in one place, the project helps learners efficiently review concepts and practice effectively for interviews.

LeetCodeAnimation is an educational open source project by MisterBooo that visually demonstrates algorithm problems from LeetCode through animations. The goal of the project is to help learners understand complex algorithmic concepts intuitively by showing step-by-step animated explanations instead of relying solely on static code or text. Each animation corresponds to a specific problem and illustrates how data structures and algorithms operate dynamically, making it easier to grasp their underlying logic. The project also includes a curated set of 40 problems from the “Sword Pointing to Offer” series—commonly asked in technical interviews—accompanied by detailed analyses and visual breakdowns. These materials are designed for both beginners starting their algorithm journey and experienced developers seeking to reinforce their understanding. Originally published through the WeChat public account “Brother Wu Learns Algorithms”, LeetCodeAnimation has become a valuable learning resource.

toBeTopJavaer is an open source knowledge base and learning roadmap designed to help developers become expert Java engineers. Created and maintained by Hollis, the project compiles a wide range of Java fundamentals, advanced features, and ecosystem knowledge into one structured guide. It covers core Java concepts, JVM internals, multithreading, frameworks, databases, system design, and interview preparation. The repository is presented in a structured, progressive format so learners can follow along step by step while also diving into specific areas of interest. Its goal is to help developers not only strengthen their Java skills but also broaden their understanding of software engineering practices, distributed systems, and career development. With practical notes, explanations, and curated resources, it serves as both a study plan for self-learners and a long-term reference for working developers.

The ZDT (Zhongwen Development Tool) is written in Java using the Eclipse RCP to help users study mandarin Chinese. The most important feature is the flashcard study feature. ZDT currently contains: * a Flashcard plugin for memorizing Chinese characters, their meaning and their pinyin/pronunciation. The user is able to import Character lists or enter them manually. This * a Dictionary search plugin with three dictionaries: ADSO, CeDict, HanDeDict. The HanDeDict is a German dictionary. It is also possible to search any word lists entered by the user using the flashcard plugin. * an Annotator plugin. The Annotator converts the Chinese characters into pinyin, using the Alphabet with accents. On the ZDT website, flashcard lists are available for some commonly used books, such as Hanyu Jiaocheng (汉语教程). User discussion can be found on: http://www.chinese-forums.com/index.php?/forum/35-zdt-flashcards-forum/ You also may choose to use Tickets -> Support (see above).

Simple Java bot, repeat a text sequence using a defined time window. You can load a text file and read it line by line in a specific time window and simulate a conversation.

PairFX is a chess pairing program specialized for youth tournaments in schools and chess clubs . No installation required! Just Unzip it and go! I created a free online/mobile version as well : https://oks.myvcc.be/pairfx-live/ (You can run any kind of tournament with it actually but it was written for chess in schools) It supports the organization of a so-called 'run through' tournament and round robin (everybody against everybody) tournaments Swiss pairings are not (yet) possible. Are you a chess teacher at school, or organize a separate tournament at the club? Try PairFX! The run through pairing system makes it possible for player to come and go whenever they want and also to keep players playing all the time. It is not round based , so not everybody has to be finished to allow new pairings to be made. This is really great when players play at different speed and works very well in the club or at school.
