    Personal Blog

    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.

    Dumper.js

    Dumper.js

    A better and pretty variable inspector for your Node.js applications

    Dumper.js is a small JavaScript utility for pretty-printing or serializing JavaScript objects and data structures in a human-readable, tree-like format — useful for debugging, logging, or inspecting complex nested data. When you pass an object (or array, or nested structure) through dumper.js, it outputs a representation that shows keys, nested depth, and structure clearly, making it easier to understand what’s inside compared to default JSON dumps or console.log clutter. ...

    Code Catalog in Python

    Code Catalog in Python

    Algorithms and data structures for review for coding interview

    code-catalog-python serves as a grab-bag of small, readable Python examples that illustrate common algorithms, data structures, and utility patterns. Each snippet aims to be self-contained and easy to study, with clear inputs, outputs, and the essential logic on display. The catalog format lets you scan for an example, copy it, and adapt it to your use case without wading through a large framework. It favors clarity over micro-optimizations so learners can grasp the idea before worrying about edge performance. ...

    PHPExcel

    Library offering classes to read from and write to spreadsheet formats

    ...Developers can create complex spreadsheets with styled cells, formulas, charts, images, and multiple sheets programmatically. It also supports reading existing files, iterating through cells, applying data validation, and converting between formats. Because it handles the details of Excel file structures—including relationships, themes, and various metadata—users don’t need to manage proprietary file internals themselves. The API allows for cell access using row/column indexes or column letters, batch updates, and streaming writes to reduce memory usage. ...

    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.

    tcomb

    tcomb

    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. ...

    seamless-immutable

    Immutable data structures for JavaScript

    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.

    Ponder

    Ponder

    C++ reflection library with Lua binding, and JSON and XML

    ...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. ...

    Skater

    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. ...

    Your basic graph

    Your basic graph

    Graph algorithms and data structures

    A graph implementation based entirely on functions. This text is about the implementation of a Go tool based entirely on functions – the API contains only immutable data types, and the code is built on top of a struct with five function fields. It’s a tool for building virtual graphs. In a virtual graph no vertices or edges are stored in memory, they are instead computed as needed. The tool is part of a larger library of generic graph algorithms.
