Golang uses handlers to create mock databases and uses interfaces to call the database
Article Introduction:I'm trying to implement unit testing for my registration handlers and database calls. However, it throws a panic error on the database call in my registered handler. It is a simple registration handler that receives json containing username, password and email. I would then use a select statement to check if that username is a duplicate within the signup handler itself. This all works when I send my post request to this handler. However, when I actually unit tested it, it didn't work and threw me two error messages. I feel like this is because the database is not initialized in the test environment, but I don't know how to do this without using a third party framework to mock the database. mistake

Multi-step processing of user programs
Article Introduction:The computer system must convert the user's high-level programming language program into machine code so that the computer's processor can run it. Multi-stepping is a term used to describe the multiple processes involved in converting a user program into executable code. User programs typically go through many different stages during their multi-step processing, including lexical analysis, syntactic analysis, semantic analysis, code creation, optimization, and linking. Each stage is essential in order to convert a user program from a high-level form into machine code that can run on a computer system. User programs differ from components of an operating system or other system software in that they are computer programs written and run by users. Most of the time, user programs are created in high-level programming languages and are designed to perform specific activities

Web apps can now use protocol handlers in Microsoft Edge
Article Introduction:Click to enter: ChatGPT Tool Plug-in Navigation Directory Microsoft announced that starting with Microsoft Edge 96, web applications will now be able to use protocol handlers in Microsoft Edge. The latest feature will allow installed web applications (or PWAs) to navigate preset or custom protocols. Installed web applications will also be able to register with the operating system as protocol handlers and be launched after calling a specific protocol. If your web application is able to register as a protocol handler, it will "integrate better with the operating system and can be set to open specific protocols." It can also be set as the default handler, which means if you are developing as an email client

What is the difference between multiprogramming and multiprocessing?
Article Introduction:Difference: Multiprogramming automatically schedules execution between jobs and shares system resources. It does not truly execute multiple jobs at the same time. Multiprocessing systems are configured with multiple CPUs and can truly execute multiple programs at the same time. To use multiprocessing effectively, multiprogramming techniques must be adopted, and multiprogramming does not in principle require the support of a multiprocessing system.
