If you look up the internet for an authorization gem for your Rails application, you will find these two most commonly used gems. They are Pundit and CanCanCan. This may leave you in a dilemma on which one to choose. Well, no worries you are in the right place.

When we look at the above image, our brain automatically registers the content more towards the mid and right side portions of the image than the left side because the intensity variations are more in the middle and right side portions of the image.
Submitting file(s) to an API in ruby might look new to many developers as there might not be many real-time use cases where you submit a file to an API unless you work on form submission where the user has to upload his/her image or something related to that. It is way easier than you can imagine, we can make use of the HTTP gem for this purpose. We chose HTTP over many other gems because of various reasons, some of them being
Docker registry is a repository of Docker images from where you can pull and push images. The registry holds different tagged versions of images. One of the most used public registries is DockerHub which involves zero maintenance and provides a ready-to-go solution. Using a public registry is suitable for small scale development.

As Deep Learning engineers, we always wanted access to powerful computers. And when it’s available for free, we would love to make full use of it. Google is providing colaboratory notebooks powered by GPUs and TPUs. But when we have huge dataset to train we will have a problem. We have ways to upload the data to the virtual machine in which colaboratory is running, but at the moment you get disconnected all the data associated to that VM is lost. So we can use our own google drive data to train and also store the trained models in drive itself.
A structured data transfer protocol. It is simpler, more compact and faster than XML because binary data is optimized for the minimum size of the message.
Nomad is a workload orchestrator built by HashiCorp. But what is a workload orchestrator? For instance, let us say you have an application that needs to be deployed. Ideally, you will find a server with the necessary resource allocation needed by the application, deploy the code in it, set up networking, manage the lifecycle of the application, etc. Handling all these manually will not enable us to scale our application. To achieve all these with ease, orchestrators comes to our rescue.
In this part, we’ll focus on fundamentals like State Management and Lifecycle in React application. We have already covered a few topics such as Code Style, Components, CSS, Props, State and Event Handling in part one of this article.
ReactJS and Vue.js are the two most popular open-source JavaScript libraries that are being used to build numerous websites today. Both ReactJS and Vue.js are lightweight and have a lot of similarities like the usage of virtual DOM, component-based architecture, usage of props, chrome Dev tools for debugging and many more. But both of them won’t exist in the absence of any significant differences.
React Hooks, a feature which is available in React v16.8, is something awesome you should know about. Let’s see, how to use state and other React features without writing a class.
