Focus The Five Best DevOps Tools DevOps emerged out of the agile software development movement and applies some similar standards to the application life cycle management (ALM) process. DevOps is hard to characterise since it’s to a greater degree a development or logic than an unbending arrangement of standards or practices. Open source DevOps tools are used to streamline software improvement and arrangement. Here’s a brief description of the five best tools amongst these.

Developers - Let's Try Image Feature Processing in Deep Learning using Convolutional Neural Networks: An Overview David H. Hubel and Torsten Wiesel laid the foundations for building the CNN (convolutional neural network) model after their studies and experiments on the human visual cortex. Since then, CNN models have been built with near human accuracy. This article explores image processing with reference to the handling of image features in CNN. It covers the building blocks of the convolution layer, the kernel, feature maps and how the activations are calculated in the convolution layer. It also provides insights into various types of activation feature maps and how these can be used to debug the CNN model to reduce computations and the size of the model.

Developers - Let's Try SPA JS: Building Cross-Platform SPAs with Less Code SPA JS is a single page application that is simplified and developed using JavaScript. It is used to create a cross-platform application using which you can develop a Web app, and the same code can also be used to develop desktop apps. If the code is bundled with the Electron software, then the result would be a desktop app, and if you put the code under a Cordova stack, then you would get Android or iOS applications. So, you can use the same code of SPA JS to develop applications for the desktop as well as the mobile.
