Hand Tracking in the Browser using Tensorflow.js and 3 lines of code.

-
Image
Handtrack.js library allows you track a user’s hand (bounding box) from an image in any orientation, in 3 lines of code. Here’s an example interface built using Handtrack.js to track hands from webcam feed. Try the  demo here. A while ago, I was really blown away by results from an experiment using  TensorFlow  object detection api to  track hands  in an image. I made the  trained model and source code available , and since then it has been used to prototype some rather interesting usecases ( a tool to help kids spell , extensions to  predict sign language ,  hand ping pong , etc). However, while many individuals wanted to experiment with the trained model, a large number still had  issues  setting up Tensorflow (installation, TF version issues, exporting graphs, etc). Luckily, Tensorflow.js addresses several of these installations/distribution issues, as it is optimized to run in the standardized environment of browsers. To...

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...
