Library for performing speech recognition, with support for several engines and APIs, online and offline. Recognize speech input from the microphone, transcribe an audio file, save audio data to an audio file. Show extended recognition results, calibrate the recognizer energy threshold for ambient noise levels (see recognizer_instance.energy_threshold for details). Listening to a microphone in the background, various other useful recognizer features. The easiest way to install this is using pip install SpeechRecognition. The first software requirement is Python 2.6, 2.7, or Python 3.3+. This is required to use the library. PyAudio is required if and only if you want to use microphone input (Microphone). PyAudio version 0.2.11+ is required, as earlier versions have known memory management bugs when recording from microphones in certain situations. To hack on this library, first make sure you have all the requirements listed in the "Requirements" section.

Hermes-powered apps launch faster, thanks to build-time precompilation of JavaScript into efficient bytecode. Hermes is small in APK size, lean on memory, and starts instantly. It won't weigh your app down. It's simple to get started with Hermes in React Native apps. Hermes is open source and implements JavaScript standards. You will now be in a directory with the output of building Hermes into CLI tools. From here you can run a piece of JavaScript. If you have an existing app based on an earlier version of React Native, you will have to upgrade it first. Each Hermes release is aimed at a specific RN version. The rule of thumb is to always follow Hermes releases strictly. Version mismatch can result in instant crash of your apps in the worst case scenario. Hermes requires Microsoft Visual C++ 2015 Redistributable

BearDB is a database provider for modern web applications and javascript frameworks. BearDB is our Relational Database System which runs on most platforms and supports multiple programming languages. A REST server allows web applications to go directly to the database. BigBear is our Large Scale Database System which supports SQL. BigBear is similar to modern distributed NoSQL database systems, with the addition of support for SQL and a REST server.

Hi, we are introducing you something new - ZZZ Knowledge Base. This is a base which stores knowledge in the form of nested sets, each set can contain a virtually unlimited number of elements and, in turn, each element can contain multiple elements. The access time from multiple ELEMENT NOT DEPEND ON THE NUMBER OF ITEMS IN IT AND PRACTICAL instantaneous! The access to knowledge base is realized through a "server" to which you can connect an unlimited number of "clients" as one computer can run multiple servers that are located in different folders and listen to different ports. Each server can create and access the unlimited knowledge bases and databases associated with other servers located on the Internet or Intranet. Knowledge bases managed by artificial intelligence language, such as executable code can be written as in external files and in the elements of the base. The Knowledge Base is powerful enough, it can be used for indexing web contents.

Build applications faster with object and file storage, user authentication, push notifications, dashboard and more out of the box. Our preferred channels of communication for help, issues and disscussion. Parse Server works with the Express web application framework. It can be added to existing web applications, or run by itself. Parse Server is continuously tested with the most recent releases of Node.js to ensure compatibility. We follow the Node.js Long Term Support plan and only test against versions that are officially supported and have not reached their end-of-life date. You can use any arbitrary string as your application id and master key. These will be used by your clients to authenticate with the Parse Server. Parse provides SDKs for all the major platforms.

The SQL Embedded Manager, is a Windows Forms light-weight implementation of the Microsoft SQL Server Management Studio, focused to supporting only all the embedded databases engines (for example, Sql Server Compact Edition, SQLite and Firebird).

A simple JDBC framework (JAR) by Jeff Smith. Employs database independent, unchecked exception code. Supports Oracle, mySQL, HSQL, and PostgreSQL--can be easily extended to new databases. See article (originally published on Developer.com ) here: http://softtechdesign.com/products/SQLExecutor/SQLExecutor.htm

By providing SDK for data exchange through blockchain, developers can more conveniently develop DAPP applications. It mainly includes the following contents:data encryption and decryption, digital signature, smart contract, event notification, data storage interface, data acquisition and query, digital currency payment, the third-party App payment interface, etc.

WhiteBear is a set of foundation classes for database engines written in Java. It supports object and relational database, is highly portable and may be used in embedded or server environment. Project has been created from scratch and plan to includes storage engine, server, SQL interpreter, ODBC, JDBC and JDO interface
