    core.match

    core.match

    An optimized pattern matching library for Clojure

    core.match is a high-performance pattern-matching library for Clojure and ClojureScript. It provides an optimized macro-based DSL for structurally matching data—such as sequences, maps, regexes—offering a clearer alternative to nested conditionals or destructuring. A symbol pattern can represent one of three behaviours. Match the value of an existing local binding. Create a "named" wildcard pattern that creates a binding of the given name to the right of the pattern row.

    Swinject

    Dependency injection framework for Swift with iOS/macOS/Linux

    Swinject is a lightweight dependency injection framework for Swift. Dependency injection (DI) is a software design pattern that implements Inversion of Control (IoC) for resolving dependencies. In the pattern, Swinject helps your app split into loosely-coupled components, which can be developed, tested, and maintained more easily. Swinject is powered by the Swift generic type system and first-class functions to define the dependencies of your app simply and fluently.

    Design Patterns for Humans

    Design Patterns for Humans

    An ultra-simplified explanation to design patterns

    Design Patterns for Humans is a developer-friendly guide that explains classic software design patterns using plain language, intuitive analogies, and succinct code examples. Instead of dense academic prose, it focuses on “why” and “when” to use a pattern, including trade-offs that help readers make pragmatic choices. The material groups patterns into categories such as creational, structural, and behavioral, mirroring common references while staying approachable for self-study. Each pattern’s section typically includes intent, real-world motivation, and an example implementation to cement understanding. ...

    Loggifly

    Loggifly

    Get Alerts from your Docker Container Logs

    ...Instead of manually scanning logs for issues or relying solely on centralized monitoring stacks, LoggiFly proactively inspects streams of container output and notifies users through services like Ntfy, Slack, Discord, Telegram, or webhooks when significant events occur. It supports plain text, regex, and multi-line pattern matching, and its flexible alert templating lets operators tailor messages for clarity and context, including attaching relevant log excerpts. Beyond notifications, LoggiFly can take automated actions such as restarting or stopping containers when specific critical patterns are detected, which is especially useful for preventing damage from misbehaving services.

    Learn Elixir

    Learn Elixir

    Learn the Elixir programming language to build functional web apps

    ...It teaches Elixir’s core types and syntax with short, runnable examples, then moves into real project work using Mix for generating apps, compiling, running tasks, managing dependencies, and creating docs. You’ll learn to write idiomatic modules and functions, use the Enum module, and practice pattern matching and the pipe operator in small, composable functions. The guide also shows how to generate API docs with ex_doc, write and run tests with ExUnit and doctest, and measure coverage—forming a complete feedback loop.

    Comprehensive study guide for coding interviews

    ...It organizes problems by topic—arrays, linked lists, stacks/queues, trees/graphs, dynamic programming, greedy, backtracking, and math—so you can study systematically. Explanations are concise but intentional, highlighting why a pattern fits, how to reason about boundary cases, and the time/space trade-offs. Many entries include template code and “swap-in” variations, helping you recognize how the same technique adapts across similar problems. The book also emphasizes problem-solving habits like deriving invariants, choosing appropriate data structures, and verifying with small counterexamples. ...

    Bolt for JavaScript

    Bolt for JavaScript

    A framework to build Slack apps using JavaScript

    ...To listen to messages that your app has access to receive, you can use the message() method which filters out events that aren’t of type message. message() accepts an optional pattern parameter of type string or RegExp object which filters out any messages that don’t match the pattern. A RegExp pattern can be used instead of a string for more granular matching. Within your listener function, say() is available whenever there is an associated conversation (for example, a conversation where the event or action which triggered the listener occurred). say() accepts a string to post simple messages and JSON payloads to send more complex messages. ...

    Functors.jl provides tools to express a powerful design pattern for dealing with large/ nested structures, as in machine learning and optimization. For large machine learning models, it can be cumbersome or inefficient to work with parameters as one big, flat vector, and structs help manage complexity; but it is also desirable to easily operate over all parameters at once, e.g. for changing precision or applying an optimizer update step.

Each exercise builds on the previous one, gradually introducing core concepts such as pattern matching, recursion, processes, and concurrency in Elixir. By debugging and filling in missing pieces, users gain practical, hands-on experience while reinforcing theoretical knowledge. The project is ideal for both complete beginners and developers transitioning from other languages who want to learn Elixir in a structured, exploratory way. ...

    ...These scalability protocols are lightweight messaging protocols that can be used to solve a number of very common messaging patterns, such as request/reply, publish/subscribe, surveyor/respondent, and so forth. These protocols can run over a variety of transports such as TCP, UNIX sockets, and even WebSocket. This pattern is useful for solving producer/consumer problems, including load-balancing. Messages flow from the push side to the pull side. If multiple peers are connected, the pattern attempts to distribute fairly. nanomsg is a socket library that provides several common communication patterns. It aims to make the networking layer fast, scalable, and easy to use. ...
