How to Secure Session Management in Node

-
In a web application, data is transferred from a browser to a server over HTTP. In modern applications, we use the HTTPS protocol, which is HTTP over TLS/SSL (secure connection), to transfer data securely. Looking at common use cases, we often encounter situations where we need to retain user state and information. However, HTTP is a stateless protocol. Sessions are used to store user information between HTTP requests. We can use sessions to store users' settings like when not authenticated. Post authentication sessions are used to identify authenticated users. Sessions fulfill an important role between user authentication and authorization. Exploring Sessions Traditionally, sessions are identifiers sent from the server and stored on the client-side. On the next request, the client sends the session token to the server. Using the identifier, the server can associate a request with a user. Session identifiers can be stored in cookies, localStorage, and sessionStorage. Session identi...

The future of Artificial Intelligence: 6 ways it will impact everyday life

Technology moves at breakneck speed, and we now have more power in our pockets than we had in our homes in the 1990s. Artificial intelligence (AI) has been a fascinating concept of science fiction for decades, but many researchers think we’re finally getting close to making AI a reality.  NPR notes that in the last few years, scientists have made breakthroughs in “machine learning,” using neural networks, which mimic the processes of real neurons. This is a type of “deep learning” that allows machines to process information for themselves on a very sophisticated level, allowing them to perform complex functions like facial recognition. Big data is speeding up the AI development process, and we may be seeing more integration of AI technology in our everyday lives relatively soon. While much of this technology is still fairly rudimentary at the moment, we can expect sophisticated AI to one day significantly impact our everyday lives. Here are 6 ways AI might affect us in the ...
