User Handling, & Security In the last installment, we learned about the different kinds of controllers that Umbraco provides us. Now we will delve into User and Member management, and how to code authentication & authorization into your Umbraco website. Security Umbraco has two distinct user types. User security for the back office and member security for the front end.
In the last few articles, we have been working with React Native and have learned how to use some of React Native’s built in component. Most recently, we learned how to navigate between different screens using React Navigation. One thing we haven’t covered yet, is getting access to the camera and camera roll in a React Native app. Now a
Prerequisites: Basic knowledge of JavaScript Outline Intro Block class USDevBlockchain Mining Transactions and rewards Transaction signature Intro In the first part of the blog, we have introduced the notion of blockchain and covered the basic concepts. You could dig a lot deeper if you want, but that is the minimum knowledge we need to move on to the next step
What’s All the Fuss About Features? Features are interesting aspects or attributes of a thing. When we read a feature story, it’s what the news room feels will be the most interesting, compelling story that draws in viewers. Similarly, when we look at a picture, or a Youtube thumbnail, various aspects of that photo or video tend to draw us
Graphs, Graph theory, Euler, and Dijkstra As tasks become more defined, the structures of data used to define them increase in complexity. Even the smallest of projects can be broken down into groups of smaller tasks, that represent even smaller sub-tasks. Graphs are a data structure that helps us deal with large amounts of complex interactions, in a static, logical
Previously, in “Exploring React Native (Continued Part 2)”, we continued to work on our simple app. The code for the app was long and was all located in one file after the article, “Exploring React Native (Continued Part 1)”. Being that React Native uses native components as building blocks, we decided to break down each part of the app into
Previously, in “Exploring React Native (Continued Part 1), we continued to work on our simple app. The app initially consisted of an Image component, Text components, state with data, a couple of TouchableOpacity buttons and styling. The app was to keep track of the number of raccoons the user saw but we wanted to add to it. So, we add
In the last article, titled “Exploring React Native”, we used a few components to create a simple app. The app consisted of an Image component, a couple Text components, data that changed with user interaction, and a couple of buttons created with the Button component and TouchableOpacity component. We styled each component and at the end, had a counter app.
