    MSI Downloader

    MSI Downloader

    MSI installers for a wide range of software and utilities

    MSI Downloader has been created for IT professionals who want a quick and easy method of downloading the latest MSI installers for various software. MSI installers are much easier to use for deployment using systems like Group Policy, Microsoft Deployment Toolkit (MDT) and Microsoft System Center Configuration Manager (SCCM). Some publishers happily supply MSI installers for their software, however, some are very hard to find. So this new tool will not only be providing the easy to find MSI installers, but also the hard to find ones and in some cases, the impossible to find ones - ones where we will create the MSI installers for them! The aim to keep all the MSI Installers within our utility fully up to date, but if you find something that is not, please let us know and we will correct it.

    Natural Docs

    Natural Docs

    Multi-language source code documentation tool

    Natural Docs is an open-source documentation generator for multiple programming languages. You document your code in a natural syntax that reads like plain English. Natural Docs then scans your code and builds high-quality HTML documentation from it. SourceForge houses the source code and issue database for the old Perl version of Natural Docs, version 1.52. It is still available but no longer being updated. Please see NaturalDocs.org for the 2.x source code and issue database. However, you can still download the both the old and the new 2.x releases of Natural Docs here.

    Foundatio

    Pluggable foundation blocks for building distributed apps

    Pluggable foundation blocks for building loosely coupled distributed apps. Includes implementations in Redis, Azure, AWS, RabbitMQ and in memory (for development). When building several big cloud applications we found a lack of great solutions (that's not to say there aren't solutions out there) for many key pieces to building scalable distributed applications while keeping the development experience simple. Wanted to build against abstract interfaces so that we could easily change implementations. Wanted the blocks to be dependency injection friendly. We were initially using an open-source Redis cache client but then it turned into a commercial product with high licensing costs. Not only that but there weren't any in-memory implementations so every developer was required to set up and configure Redis. We initially looked at NServiceBus (a great product) but it had high licensing costs (they have to eat too) and was not OSS friendly.

    Microsoft Authentication Library .NET

    Microsoft Authentication Library .NET

    Microsoft Authentication Library (MSAL) for .NET

    MSAL.NET (Microsoft.Identity.Client) is an authentication library that enables you to acquire tokens from Azure AD, to access protected Web APIs (Microsoft APIs or applications registered with Azure Active Directory). MSAL.NET is available on several .NET platforms (Desktop, Universal Windows Platform, Xamarin Android, Xamarin iOS, Windows 8.1, and .NET Core). The MSAL library for .NET is part of the Microsoft identity platform for developers (formerly named Azure AD) v2.0. It enables you to acquire security tokens to call protected APIs. It uses industry-standard OAuth2 and OpenID Connect. The library also supports Azure AD B2C. Acquiring a token interactively enables the application to acquire a token after authenticating the user through an interactive sign-in. There are specificities, though depending on the platforms (Xamarin Android, Xamarin iOS, or UWP)

    Orleans

    Orleans

    Orleans is a cross-platform framework for building distributed apps

    Orleans builds on the developer productivity of .NET and brings it to the world of distributed applications, such as cloud services. Orleans scales from a single on-premises server to globally distributed, highly-available applications in the cloud. Orleans takes familiar concepts like objects, interfaces, async/await, and try/catch and extends them to multi-server environments. As such, it helps developers experienced with single-server applications transition to building resilient, scalable cloud services and other distributed applications. For this reason, Orleans has often been referred to as "Distributed .NET". It was created by Microsoft Research and introduced the Virtual Actor Model as a novel approach to building a new generation of distributed systems for the Cloud era. The core contribution of Orleans is its programming model which tames the complexity inherent to highly-parallel distributed systems without restricting capabilities or imposing onerous constraints.

    Pixeval is a third-party proxy-free P station client developed by me as an amateur.

It has been open sourced on Github based on the AGPL protocol . The project was conceived in 2018. At that time, the api of the P station was written in Java. At that time, it could also be accessed by modifying the hosts method. After that, GFW The blocking strategy was upgraded, and DNS pollution was upgraded to SNI blocking, so I went to find information to understand the different blocking levels and blocking mechanisms of GFW. I started writing this project in the second half of 2019, which took about 3 months. (Actually, the realization of this project is partly inspired by Notsfsssf.

    reko

    reko

    Reko is a binary decompiler

    Reko (Swedish: "decent, obliging") is a decompiler for machine code binaries. This project is freely available under the GNU General Public License. The project consists of front ends, core decompiler engine, and back ends to help it achieve its goals. A command line, a Windows GUI, and a ASP.NET front end exist at the time of writing. The decompiler engine receives inputs from the front ends in the form of either individual executable files or decompiler project files. Reko project files contain additional information about a binary file, helpful to the decompilation process or for formatting the output. The decompiler engine then proceeds to analyze the input binary. Reko has the ambition of supporting decompilation of various processor architectures and executable file formats with minimal user intervention. For a complete list, see the supported binaries page.

    Entity Framework 6 (EF6) is a proven object-relational (O/RM) mapper for .NET with many years of feature development and stabilization. Like O/RM, EF6 reduces the impedance mismatch between the relational and object-oriented worlds, allowing developers to write applications that interact with data stored in relational databases with strongly typed .NET objects that represent the domain of the database. application, and eliminate the need for much of the data access "mechanical" code that you would normally write. Mapping POCO entity classes that do not depend on any EF type. Models can be generated from existing databases and then manually edited, or they can be created from scratch and then used to generate new databases. Integration with .NET Framework application models, including ASP.NET, and through data binding, with WPF and WinForms. Database connectivity based on ADO.NET and various providers available to connect to SQL Server, Oracle, MySQL, SQLite, PostgreSQL, DB2, etc.

    Windows Presentation Foundation (WPF)

    Windows Presentation Foundation (WPF)

    Framework for building Windows desktop applications

    Windows Presentation Foundation (WPF) is a UI framework for building Windows desktop applications. WPF supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding and documents. WPF uses the Extensible Application Markup Language (XAML) to provide a declarative model for application programming. WPF applications are based on a vector graphics architecture. This enables applications to look great on high DPI monitors, as they can be infinitely scaled. WPF also includes a flexible hosting model, which makes it straightforward to host a video in a button, for example. The visual designer provided in Visual Studio makes it easy to build WPF application, with drag-in-drop and/or direct editing of XAML markup. WinForms is another UI framework for building Windows desktop applications that is supported on .NET (6.0.x/5.0.x/3.1.x). WPF and WinForms applications only run on Windows.

For Unity, please consider using OpenCV for Unity or some other solutions. OpenCvSharp does not support CUDA. If you want to use the CUDA features, you need to customize the native bindings yourself. Objects of classes, such as Mat and MatExpr, have unmanaged resources and need to be manually released by calling the Dispose() method. Worst of all, the +, -, *, and other operators create new objects each time, and these objects need to be disposed of, or there will be memory leaks. Despite the using syntax, the code still looks very verbose.
