Nearly 60 years ago,  Gordon Moore , the co-founder of Intel, coined " Moore's Law ," a prediction that would set the pace for the digital revolution. The law stated that computing abilities, over time, would radically increase in power while decreasing in relative cost, all at an exponential rate. This insight, along with the hard work of many computer scientists and engineers, has fueled the rapid growth of the technology sector. The industry has quickly become a staple component of our modern economy. The five biggest technology companies (Apple, Alphabet, Facebook, Amazon, and Microsoft) together made up a whopping  37 percent of the S&P 500's total gains  in 2017. Federal investments in the digital sector could  reach up to $95 billion  in the coming year. And, internationally, the public will  spend up to $3.4 trillion  on digital services by 2020. Consumers and enterprises have a lot of potentials to look forward to, as frontier ...

How Facebook scales Artificial Intelligence

Facebook's products and services are powered by machine learning. Powerful GPUs have been one of the key enablers, but it takes a lot more hardware and software to serve billions of users. Most of Facebook's two billion users have little idea how much the service leans on artificial intelligence to operate at such a vast scale. Facebook products such as the News Feed, Search and Ads use machine learning, and behind the scenes, it powers services such as facial recognition and tagging, language translation, speech recognition, content understanding and anomaly detection to spot fake accounts and objectionable content. The numbers are staggering. In all, Facebook's machine learning systems handle more than 200 trillion predictions and five billion translations per day. Facebook's algorithms automatically remove millions of fake accounts every day. In a keynote at this year's  International Symposium on Computer Architecture (ISCA) , Dr. Kim Hazelwood, the...

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...
