Store5
A Kotlin Multiplatform library for building network-resilient apps
Modern software needs data representations to be fluid and always available. Users expect their UI experience to never be compromised (blocked) by new data loads. Whether an application is social, news or business-to-business, users expect a seamless experience both online and offline. International users expect minimal data downloads as many megabytes of downloaded data can quickly result in astronomical phone bills. Store is a typed repository that returns a flow of Data /Loading /Error from local and network data sources. -

Superfine
Absolutely minimal view layer for building web interfaces
Superfine is a minimal view layer for building web interfaces. Think Hyperapp without the framework—no state machines, effects, or subscriptions, just the absolute bare minimum (1 kB minified+gzipped). Mix it with your favorite state management library or use it standalone for maximum flexibility. When describing how a page looks in Superfine, we don't write markup. Instead, we use the h() and text() functions to create a lightweight representation of the DOM (or virtual DOM for short), and patch() to actually render the DOM. Superfine won't re-create the entire DOM every time we use patch(). By comparing the old and new virtual DOM we are able to change only the parts of the DOM that need to change instead of rendering everything from scratch. -

Today I Learned
This “Today I Learned” repository is a living notebook of concise tips, commands, and gotchas collected across many tools and languages. Entries are intentionally short—often a paragraph and an example—so they’re easy to search, skim, and apply in a pinch. Topics span everyday developer concerns: shell one-liners, Git incantations, editor tricks, language quirks, and small debugging patterns that save time. Because each note is atomic, the collection grows organically without becoming a tangled tutorial or book; readers can dip in anywhere and learn something useful in a minute. The repo format also encourages community contributions and personal forking, making it a template for teams to build their own shared knowledge base. Over years, it becomes both a reference and a record of the author’s learning journey, with the git history revealing how practices evolved. -

TableView for Android
Powerful Android library for displaying complex data structures
TableView is a powerful Android library for displaying complex data structures and rendering tabular data composed of rows, columns and cells. TableView relies on a separate model object to hold and represent the data it displays. This repository also contains a sample app that is designed to show you how to create your own TableView in your application. -

The Agda standard library
The Agda standard library
The standard library aims to contain all the tools needed to write both programs and proofs easily. While we always try and write efficient code, we prioritize ease of proof over type-checking and normalization performance. If computational performance is important to you, then perhaps try agda-prelude instead. Agda is a dependently typed programming language. It is an extension of Martin-Löf’s type theory and is the latest in the tradition of languages developed in the programming logic group at Chalmers. Other languages in this tradition are Alf, Alfa, Agda 1, Cayenne. Some other loosely related languages are Coq, Epigram, Idris, and Lean. -

Underscore.js
JavaScript's utility belt
Underscore.js is a JavaScript utility-library created by Jeremy Ashkenas that provides a broad set of functions for working with arrays, objects, functions, and other data types — essentially a “utility belt” for functional programming in JS. Instead of extending built-in objects or modifying prototypes, Underscore provides its helpers in a single _ namespace, enabling cross-browser support and consistent behaviour across environments. It offers map/filter/reduce, deep-cloning, templating, object traversal, function binding, and more, which makes it easier to write concise, expressive code rather than verbose loops and conditional logic. Many other libraries and frameworks (including Backbone) historically depended on or partnered with Underscore for their utility functions. Even though ES6+ and Lodash have overshadowed some of its role, Underscore remains influential and educational for how to design utility APIs. -

Veldrid
A low-level, portable graphics library for .NET
Veldrid is a low-level, portable graphics library for .NET, providing a unified API over multiple graphics backends such as Direct3D, Vulkan, OpenGL, and Metal. It enables developers to write high-performance, cross-platform graphics applications without being tied to a specific graphics API. Veldrid is suitable for game development, simulations, and other applications requiring advanced graphics capabilities. -

WhichBrowser
Browser sniffing gone too far — A useragent parser library for PHP
This is an extremely complicated and almost completely useless browser-sniffing library. Useless because you shouldn't use browser sniffing. So stop right now and go read something about feature detecting instead. I'm serious. Go away. You'll thank me later. There is always an exception to the rule. There are valid reasons to do browser sniffing: to improve the user experience or to gather intelligence about which browsers are used on your website. My website is html5test.com and I wanted to know which score belongs to which browser. To do that you need a browser sniffing library. Almost all browsers say they are Netscape 5 and almost all WebKit browsers say they are based on Gecko. Even Internet Explorer 11 now no longer claims to be IE at all, but instead, an unnamed browser that is like Gecko. And it gets worse. That is why it is complicated. -

Xabber
Open-source XMPP client for Android
Open source Jabber (XMPP) client with multi-account support, clean and simple interface. Being both free (as in freedom!) and ad-free, Xabber is designed to be the best Jabber client for Android. Xabber uses Gradle build system. The only specific thing is git submodule for the MemorizingTrustManager library. Since it’s inception in 2011, Xabber has grown to be a number one XMPP client for Android. It is fast, reliable and packed with lots of features that make it more advanced than most desktop clients. Xabber interface was perfected over many years to give a very clear yet informative presentation of your contacts and chats. Great amount of details are shown in a subtle way to not obscure your view. Internet connection is not as reliable as we’d like on mobile networks, users often experience connection loss. Xabber for Android was optimized to ensure low battery usage and to quickly reconnect. -

XcodeProj
Read, update and write your Xcode projects
XcodeProj is a library written in Swift for parsing and working with Xcode projects. It's heavily inspired by CocoaPods XcodeProj and xcode. Using swift-sh you can automate project-tasks using scripts, for example, we can make a script that keeps a project’s version key in sync with the current git tag that represents the project’s version. Future adaption could easily include determining the version and bumping it automatically. If so, we recommend using a library that provides a Version object. Want to start using XcodeProj? Start by digging into our documentation which will help you get familiar with the API and get to know more about the Xcode projects structure. -

Yasumi
The easy PHP Library for calculating holidays
Yasumi (Japanese for 'Holiday'「休み」) is the easy PHP library that helps you retrieve the dates and names of holidays and other special celebrations from various countries/states. It is calculation and rule driven avoiding the need of a comprehensive database. Many services exist that can provide holiday information, however are either not entirely free or only offer limited information. In addition, no exhaustive PHP library exists today covering a wide range of holidays and countries. PEAR's Date_Holidays library was a similar attempt, however it hasn't been updated for a long time. The goal of Yasumi is to be powerful while remaining lightweight, by utilizing PHP native classes wherever possible. Yasumi's calculation is provider-based (i.e. by country/state), making it easy to add new holiday providers that calculate holidays. -
