MongoDB is a popular NoSQL database that makes it a great backend for Web APIs which lend themselves towards a document store rather than a relational store. In this blog we show how you can use MongoDB with ASP.NET Web API to build an ApiController with support for HTTP GET, PUT, POST, and DELETE.

meSing.js is a JavaScript singing synthesis library that uses the Web Audio API's DSP capabilities in conjunction with the meSpeak.js speech synthesis library to provide a vocal synthesizer for the web. First, the lyrics with corresponding MIDI notes are parsed and fed to meSpeak.js; the resulting text-to-speech output is then converted into a series of AudioBufferSourceNodes, which are subsequently processed and adjusted for pitch, rhythm, and expression.

protobuf.js is a pure JavaScript implementation with TypeScript support for node.js and the browser. It's easy to use, blazingly fast and works out of the box with .proto files!
Modern software development practices value quick and continuous updates, following processes that minimize the impact of software failures. As important as identifying bugs early, finding out if changes are improving business value are equally important. These practices can only work when a monitoring solution is in place. This article explores options for adding observability to .NET Core apps. They have been collected based on interactions with customers using .NET Core in different environments. We will be looking into OpenTelemetry and Application Insights SDKs to add observability to a sample distributed application.
We're going to use Dapper.NET on our project; that much is not in doubt. However, we're not going to start development with it, and it will not be the only ORM in use. The plan is to develop this project using Entity Framework, and later optimize to use Dapper.NET in certain scenarios where the system needs a performance boost.
JSON Web Token چیست؟
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with HMAC algorithm) or a public/private key pair using RSA.
