Guide to Technical Interviews
Guided collection and roadmap for preparing technical interviews
This repository is a guided collection and roadmap for preparing technical interviews, covering the gamut from algorithmic challenges and data structures to system design and behavioral preparation. It consolidates resources like interview question lists, practice platforms, mock interview sites, and recommended books or blogs. For individuals targeting big-tech or rigorous interview processes, this acts as a structured study guide rather than a random list of links. The README breaks down preparation into categories — coding problems, system design, mock interview sites — so you can identify gap areas and allocate study time accordingly. Because interviews blend knowledge, strategy and habits (e.g., whiteboarding, communication, trade-off reasoning), the repository also emphasizes preparation workflows rather than just raw practice. It is therefore, an excellent companion for developers who have the technical skill and now need to convert it into interview readiness. -

Guides
Design and development guides
This repository is a curated collection of links and resources aimed at helping programmers improve their craft, especially with regard to coding style, design practices, development workflows, and engineering discipline. The idea is that instead of reinventing style guides or best-practices from scratch, developers can reference this repository for high-quality external guides, articles, and checklists across many languages and ecosystems. It is not a library in the usual sense, but acts as a “meta-guide” index — a directory of authoritative resources rather than runnable code. The content is organized as Markdown links and descriptions, making it easy to scan and browse for relevant topics (for instance style guides for Ruby, JavaScript, CSS, deployment, architecture). Because it is community-driven and open to contributions, you’ll find new links and categories being added over time, helping it remain relevant. -

Gulp-Cheatsheet
A cheatsheet for gulp.js
The gulp-cheatsheet repository is a compact, printable reference guide for Gulp.js, summarizing common commands, patterns, and usage examples in both JavaScript and CoffeeScript. It’s designed to be easily printed or posted beside a workstation, acting as a quick lookup for task definitions, streams, watching, and build workflows. The cheatsheet covers essential topics like Gulp installation, defining tasks, piping streams, watchers, and handling asynchronous tasks. It includes multilingual PDF versions (English, Japanese, Chinese) so users around the world can use it in their preferred language. The repository is lightweight (mostly documentation and examples), licensed under MIT, and maintained as a community reference rather than a full tool or plugin. -

Guzzle Promises
A library for PHP with synchronous support
Promises/A+ implementation that handles promise chaining and resolution iteratively, allowing for "infinite" promise chaining while keeping the stack size constant. A promise represents the eventual result of an asynchronous operation. The primary way of interacting with a promise is through its then method, which registers callbacks to receive either a promise's eventual value or the reason why the promise cannot be fulfilled. Callbacks are registered with the then method by providing an optional $onFulfilled followed by an optional $onRejected function. Resolving a promise means that you either fulfill a promise with a value or reject a promise with a reason. Resolving a promises triggers callbacks registered with the promises's then method. These callbacks are triggered only once and in the order in which they were added. -

HARPOON 2
Getting you where you want with the fewest keystrokes
HARPOON 2 is a highly popular Neovim plugin created by ThePrimeagen that enhances editor navigation by letting users mark and quickly jump to frequently used files and terminals within their Neovim workflow. Unlike traditional global marks in Vim, Harpoon’s marks are per-project and automatically updated, meaning they follow files even as content changes, which streamlines switching between contextually relevant files during development. It comes with an intuitive menu system that lists marked files and offers commands to add, remove, or navigate to those files with minimal keystrokes. In addition to file marks, Harpoon also supports storing terminal commands and sending them to persistent terminals, allowing workflows that blend code editing with compilation, testing, or server control all from within Neovim. -

HASEM
Matrix c++ library solving any linear algebra problems
HASEM is a c++ template library, it can be easily configure as a expression template. HASEM solves any linear equation of any kind, it might be homogenous/none homogenous, compute the inverse of square/none square matrices, find LU decomposition, find determinant and rank of matrices, calculate the characteristic polynomial of matrices, find the eigenvalues and eigen vectors and so on. HASEM uses many methods, therefore, you are not limited to just one method, you have the choice to define your desire method as default one. With over 200 member functions and over 40 none member functions HASEM is almost able to solve any linear algebra problems. HASEM support multidimensional as well, you can mix up your multidimensional matrix with other matrices with different size, and apply all operations on them as well.It's possible to save the computed matrix into files, and when required read it from files and load the data into matrices. It is also very easy to add your extension to HASEM. -

HE-Collection
HE-Collections - independent from hashCode() and equals(Object)
The Java-Standard-Collections demand correct implementations of the hashCode()- and the equals(Object)- method from any object that is to be stored in a collection. Otherwise, the behavoir of the Java-Standard-Collection is not determined. HE-Collections where implemente in order to store objects in a collection, that brake the contract between equals(Object) and hashCode(), HE-Collections behave predictably even if they contain objects that don't obey the contract. The name "HE" stands for Hashcode and Equals. -

HEIMDALL
High-End Interface for Monitoring & spatial Data Analysis using L2Norm
HEIMDALL, short for High-End Interface for Monitoring and spatial Data Analysis using L2-Norm, is a set of public libraries written in JAVA which contains routines and algorithms for geodetic hardware connection. To observe objects (in general spatial points) continuous, HEIMDALL’s programmable logic arrays can be used to design monitoring systems. For data analysis an interface to the least-squares program JAG3D can be provided. The serial communication with e.g. inclination sensors, meteorological stations or total stations is handled by the library RXTX. If only a proprietary communication via dynamic-link library (dll are not shared by the project) is supported by the devices, JNA is resorted. Notice, HEIMDALL is not a stand-alone monitoring application. It is only a set of libraries. -

HSharp
HSharp is a library used to analyze markup language like HTML
HSharp appears to be an experimental C#/.NET project exploring higher-level abstractions or helper patterns (the naming hints at “H#” as a layer or framework on top of C#). It groups together utilities, base classes, and conventions so that common app logic can be written faster and with less boilerplate. The repo acts as a sandbox for testing these patterns in real code, which is helpful if you want to see how the author structures services, models, or infrastructure concerns. Because it’s source-first, you can cherry-pick the parts you want into your own .NET apps and ignore the rest. The idea is to make everyday C# tasks (initialization, configuration, helpers) feel more concise and expressive. Over time it can grow into a personal toolkit for the author and anyone who likes the same idioms. -

HTML5 Demos and Examples
Collection of hacks and demos showing capability of HTML5 apps
HTML5 Demos and Examples is a classic collection of HTML5 experiments and demonstration files created to show the capabilities of modern web APIs and browser technologies during the rise of HTML5. The repository is an archive of interactive examples—ranging from canvas tricks to video, audio, drag-and-drop, WebSockets, and more—that illustrate how HTML, CSS, and JavaScript can combine to build rich, browser-centric experiences without plugins. Each demo is a self-contained piece of code you can open, explore, and learn from, and the collection was curated to help developers grasp emerging standards at a time when HTML5 was gaining traction and not yet ubiquitous. Though no longer actively maintained, the archive still contains hundreds of creative examples that can teach fundamentals and spur experimentation with web features. Developers historically used it as a reference when testing browser support for features or teaching newcomers how specific APIs behave in real code.
