google-java-format
Reformats Java source code to comply with Google Java Style
google-java-format is a program that reformats Java source code to comply with Google Java Style. The formatter can act on whole files, on limited lines, on specific offsets, passing through to standard-out (default) or altered in-place. There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format. The formatter can be used in software that generates java to output more legible java code. Just include the library in your maven/gradle/etc. configuration. A google-java-format IntelliJ plugin is available from the plugin repository. To install it, go to your IDE's settings and select the Plugins category. Click the Marketplace tab, search for the google-java-format plugin, and click the Install button. -

Mozilla JPEG Encoder Project
Improved JPEG encoder
MozJPEG improves JPEG compression efficiency achieving higher visual quality and smaller file sizes at the same time. It is compatible with the JPEG standard, and the vast majority of the world's deployed JPEG decoders. MozJPEG is compatible with the libjpeg API and ABI. It is intended to be a drop-in replacement for libjpeg. MozJPEG is a strict superset of libjpeg-turbo's functionality. All MozJPEG's improvements can be disabled at run time, and in that case it behaves exactly like libjpeg-turbo. MozJPEG is meant to be used as a library in graphics programs and image processing tools. We include a demo cjpeg command-line tool, but it's not intended for serious use. We encourage authors of graphics programs to use libjpeg's C API and link with MozJPEG library instead. Progressive encoding with "jpegrescan" optimization. It can be applied to any JPEG file (with jpegtran) to losslessly reduce file size. -

Mercure
Server-sent live updates, protocol and reference implementation
Mercure is an open protocol for real-time communications designed to be fast, reliable and battery-efficient. It is a modern and convenient replacement for both the WebSocket API and the higher-level libraries and services relying on it. Mercure is especially useful to add streaming and asynchronous capabilities to REST and GraphQL APIs. Because it is a thin layer on top of HTTP and SSE, Mercure is natively supported by modern web browsers, mobile applications, and IoT devices. A free (as in beer, and as in speech) reference server, as well as a hosted service, are available. Designed for REST and GraphQL. Private updates (JWT authorization). Presence API and subscription events. Event store. Compatible with serverless, PHP, and the like. Supports end-to-end encryption. Reading the documentation is an excellent way to discover Mercure. -

Awesome Blazor
Resources for Blazor, a .NET web framework using C#/Razor
Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. Blazor is a feature of ASP.NET, the popular web development framework that extends the .NET developer platform with tools and libraries for building web apps. Blazor can run your client-side C# code directly in the browser, using WebAssembly. Because it's real .NET running on WebAssembly, you can re-use code and libraries from server-side parts of your application. Alternatively, Blazor can run your client logic on the server. Client UI events are sent back to the server using SignalR, a real-time messaging framework. Once execution completes, the required UI changes are sent to the client and merged into the DOM. -

Sizzle
A sizzlin' hot selector engine
A pure-JavaScript CSS selector engine designed to be easily dropped in to a host library. Browser support may differ between standalone Sizzle and libraries that include Sizzle. Please report issues on Sizzle's issue tracker, rather than the trackers for disparate libraries. In order to build Sizzle, you should have Node.js/npm latest and git 1.7 or later (earlier versions might work OK, but are not tested). For Windows you have to download and install git and Node.js. Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js. Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source if you swing that way. Workarounds for Internet Explorer 6 are still in the code but the browser is no longer actively tested. Sizzle supports virtually all CSS 3 Selectors, including escaped selectors (.foo\+bar), Unicode selectors, and more. -

Created by professional front-end, for full-level front-end and back-end developers, a low-threshold, out-of-the-box front-end UI solution. Layui (homonym: UI-like) is a front-end UI framework written with its own module specifications, following the writing and organization of native HTML/CSS/JS, with a very low threshold and ready to use. Its exterior is minimalist, but it does not lose its fullness. The volume is light and the components are abundant. Every detail from the core code to the API has been carefully crafted, which is very suitable for the rapid development of the interface. The first version of layui was released in the golden autumn of 2016. It is different from those UI frameworks based on the underlying MVVM. -

You are free to make use of those check points for your own needs, but you can also simply rely on our score indicator, which is based on the whole analysis, in order to quickly decide which addresses to keep or better to drop. (Basically with a score from 90 to 100 you are good to go) In addition, we offer a Windows Desktop software making a simple use of our API. -

btrxml
Basic, Tiny, Reader for XML
A very basic, portable, tiny parser for XML, written in C under the zlib license. It is designed to be used in memory constrained environments (smartphones for example). The end result will be a "DOM-like" collection of memory. A lot of things were chopped away to deliver the very basic support for XML, and this project does not aim to become a fully compliant parser; keep it basic, stay basic. Part of the design goal is to jam all of this in to one .C file and one .H file while giving other developers a somewhat convenient API. Check the project website for more information about what btrxml is, does, won't do, example usage, and stuff like this. -
