    Specter

    Specter

    Clojure(Script)'s missing piece

    Specter is a powerful Clojure (and ClojureScript) library that revolutionizes navigation and manipulation of deeply nested and recursive data structures through a flexible, high-performance API beyond what vanilla Clojure offers. Specter has an extremely simple core, just a single abstraction called "navigator". Queries and transforms are done by composing navigators into a "path" precisely targeting what you want to retrieve or change. Navigators can be composed with any other navigators, allowing sophisticated manipulations to be expressed very concisely. ...

    Personal Blog

    One article per week, the content is concise, neither salty nor light

    ...The README and index emphasize that the blog (in this repo) is paused and that new content is primarily delivered via the WeChat channel, but the GitHub repo remains the canonical archive of links and categories. Articles are grouped by topic domains such as architecture, Spring Boot, Spring Cloud, Dubbo, Hystrix, Kafka, Redis, gateways, microservices, JVM tuning, and data structures, with each entry linking out to full posts on iocoder.cn. This makes the repo act as a navigable table of contents and knowledge map for a large body of Chinese-language backend engineering content. It also includes “toolbox” and miscellaneous categories.

    LayoutKit

    LayoutKit

    LayoutKit is a fast view layout library for iOS, macOS, and tvOS

    ...LayoutKit is as fast as manual layout code and is significantly faster than Auto Layout.Layouts can be computed in a background thread so user interactions are not interrupted. Layouts are declared with immutable data structures. This makes layout code easier to develop, document, code review, test, debug, profile, and maintain. Layout results are immutable data structures so they can be precomputed in the background and cached to increase user perceived performance.

    Powerful search library, best suited for computer-aided translation

    ...It uses a RAM stored index, which takes up approximately 600MB of memory for a corpus of 2 million sentences. It is based on the idea of a suffix array, enhanced by the presence of other auxiliary data structures. The effects are stunning - Concordia is able to do simple substring lookup at the pace of 5000 queries per second (on personal PC) - a speed which can not be achieved by any other search library. Moreover, Concordia can perform its own "concordia search". For a given input sentece, all substring matches covering this sentence are retrieved. ...

    Play-With-Sort-OC

    Play-With-Sort-OC

    Repository implemented in Objective-C with sorting algorithms

    ...The goal is educational; by showing how each algorithm works with animations or clear visualizations in an iOS/Objective-C context, the author helps developers understand not just the “how” but also the “why” behind each algorithm. The repo is especially suited for developers working in the Apple ecosystem (Objective-C, Xcode) who want to build foundational knowledge in data structures and algorithms. By making the code accessible, it lowers the barrier to exploring algorithm performance, variant comparisons, and understanding underlying complexity. For learners, it offers a bridge between abstract algorithm descriptions in textbooks and real code you can compile, run, tweak, and visualize.

    Type checking and DDD for JavaScript

    tcomb is a JavaScript library for defining and checking runtime types in Node.js and browser environments. It gives developers a concise syntax for modeling values, structures, interfaces, enums, unions, refinements, and other domain-level constraints. The library is useful in JavaScript projects where static type information is unavailable or insufficient at runtime. It can validate external inputs, document data expectations, and support safer programming patterns without requiring a full type system migration. tcomb also serves as the foundation for related projects such as tcomb-validation and tcomb-form. ...

    Immutable JS data structures which are backwards-compatible with normal Arrays and Objects. Use them in for loops, pass them to functions expecting vanilla JavaScript data structures, etc. Whenever you deeply clone large nested objects, it should typically go much faster with Immutable data structures. This is because the library reuses the existing nested objects rather than instantiating new ones.

    ...It provides an abstraction for most of the high-level concepts of C++ like classes, enumerations, properties, functions, and objects. By wrapping all these concepts into abstract structures, Ponder provides an extra layer of flexibility to programs and allows them to expose and manipulate their data structures at runtime. Many applications can take advantage of Ponder, in order to automate tasks that would otherwise require a huge amount of work. For example, Ponder can be used to expose and edit objects' attributes in a graphical user interface. ...

    Python library for model interpretation/explanations

    Skater is a unified framework to enable Model Interpretation for all forms of the model to help one build an Interpretable machine learning system often needed for real-world use-cases(** we are actively working towards to enabling faithful interpretability for all forms models). It is an open-source python library designed to demystify the learned structures of a black box model both globally(inference on the basis of a complete data set) and locally(inference about an individual prediction). The concept of model interpretability in the field of machine learning is still new, largely subjective, and, at times, controversial. Model interpretation is the ability to explain and validate the decisions of a predictive model to enable fairness, accountability, and transparency in algorithmic decision-making. ...
