Who isn’t getting into Bitcoin these days? In the past year, the value of Bitcoin alone is creating huge FOMO, and driving increasing investments into cryptocurrencies. With this massive influx of new cash in cryptocurrencies like Bitcoin, Ethereum, Monero, and Ripple — blockchain technology (which is the foundation of all cryptocurrency) has become an area of intense technical study. At its core, blockchain technology simply maintains a decentralized log of transactions that can be easily shared across many nodes (miners).
In this post, I’ll show you how to add authentication to an Ionic progressive web app (PWA). PWAs are more developer-friendly to distribute than mobile apps. Not only that, but I’ll show you how to use cloud services like Okta and Firebase to make things even simpler.
Today’s internet users expect a personalized experience. Developers must learn to develop websites that provide that personalized experience while keeping their user’s information private. Modern web applications also tend to have a server-side API and a client-side user interface. it can be challenging to get make both ends aware of the currently logged in user. In this tutorial, I will walk you through setting up a Node API that feeds a React UI, and build a user registration that keeps the user’s information private and personal.
In this tutorial, I won’t use any state management libraries like Redux or ReduxThunk. In a more robust application, you’ll probably want to do that, but it will be easy to wire up Redux and ReduxThunk and then add the fetch statements used here as your thunks. For the sake of simplicity, and to keep this article focused on adding user management, I’ll be adding fetch statements into componentDidMount functions.

I got into Bitcoin back in 2011. Since then, I’ve been a fan of cryptocurrencies and have always had an interest in them. I’ve also built several Bitcoin projects over the years (an information website, an ecommerce site, and several others) to help promote the usage of the cryptocurrency (while having some fun).
The idea of being able to send and receive money almost instantly from anywhere in the world with no middleman is really appealing to a lot of people.
In this post, we will discuss more obfuscation, where it is used, and its advantages.
What Is Obfuscation?
Obfuscation is the deliberate act of creating obfuscated code, i.e. source or machine code that is difficult for humans to understand. It is something similar to encryption, but a machine can understand the code and is able to execute: it.
In fact, nowadays, we don’t have to fear it anymore. One can set up a dev environment where tools decide what transformations the code needs and what polyfills to load depending on the selected target (list of user agents to support). The only thing those people need to start “a new life” is a proper setup.
Crafter CMS support content inheritance out of the box and supports it via a pluggable mechanism that allows developers to augment or override what’s out of the box. In this article, we’ll dig into the basics of this functionality.
Content inheritance is the ability of the CMS to centrally manage content values. Updating this content in one place automatically updates the value everywhere else. This goes far beyond simple “shared components" in the sense that, as far as the system is concerned, the inherited values, in fact, belong to the content in question. In general, with inherited content you may:
When you want to work with Ruby on Rails models, even if you’re just playing around, you have to go through a few steps: Create an app directory Create a database Generate model classes Run migrations But sometimes you need…

NPrinting is important for many users. In the 2017 June release, on-demand reporting is enabled with the NPrinting API. Immediately after the release, the above question was raised to me. I spent a few days trying to prototype a solution but ended up with something that is so simple that anyone can do it in 10 minutes. Frustrating? Yes, because I spent so much time on something that is just a little bit better than “Hello, World!” On the other hand, simple is awesome; simple means even a non-technical user can implement it without problem. Pretty cool.
With that, I’m sharing my experience in case I can help others stuck with a similar problem.
A filter in Crafter is a Groovy-based controller that allows you to intercept inbound requests for content and API responses and dynamically apply rules, modify the request or transform the response. A Crafter Filter has the same interface and mechanics as a Java J2EE Servlet Filter. Some examples of filter use are:
Apply security rules: Check for SAML2, Site Minder, or other security tokens before allowing the request to proceed.
Active Record: Example: before serving the requested resource, look up and load the user’s profile into the request so it is available to all components of the system.
Apply compression: Gzip all of the data returned by the requested resource (page, API, etc)
In this article, we’ll learn the specific mechanics of creating and configuring a filter in Crafter CMS.
