Two ways to use JavaScript in Jupyter Notebook (using Javascript magic / Node js)
Two ways to run JavaScript in Jupyter Notebook:
- Client side javascript using IPython built-in magic commands;
- Server side Node javascript using Javascript kernel for the Jupyter notebook.
Dependency Inversion and Inversion of Control
Dependency Inversion
The Dependency Inversion Principle states that:
- High level modules should not depend upon low level modules. Both should depend upon abstractions.
- Abstractions should not depend upon details. Details should depend upon abstractions.
Design Patterns (Java)
The design patterns are strategies for solving common object-oriented design problems. Using the design patterns you can make your code more flexible, reusable and maintainable. We must use the design patterns during the analysis and requirement phase of SDLC (Software Development Life Cycle).
SQL Injection
SQL injection is a technique where malicious users can inject SQL commands into an SQL statement, via web page input. Injected SQL commands can alter SQL statement and compromise the security of a web application.
Cross-site request forgery
Cross-Site Request Forgery (CSRF) is a type of attack that occurs when a malicious Web site, email, blog, instant message, or program causes a user’s Web browser to perform an unwanted action on a trusted site for which the user is currently authenticated.
Web Services
A Web Service is a software application identified by a URI (Uniform Resource Identifier) whose interfaces and binding are capable of being defined, described and discovered by XML artifacts and [that] supports direct interactions with other software applications using XML based messages via Internet-based protocols (HTTP, HTTPS, SMTP).
