Developers - new versions of GCC, Node.js, PHP, Python for Red Hat Enterprise Linux & OpenShift Container Platform. Plus new compilers: Clang/LLVM, Go, Rust

I've started an interesting exploration on the integration of Microsoft Windows Containers and Linux Containers in an OCP Environment. This allows a true bi-modal IT technical implementation by combining the strength of both platforms into one cluster. So, I start this off, with the deployment of an OpenShift Cluster on Azure, using the 3.6 reference architecture . After this is run, I used the Azure Portal to add a Windows Server 2016 Node to the cluster. So if you look...

Building a docker formatted container image for a Node.js application There are 2 main strategies for building an image for a Node.js Application. The most common strategy is simply using a Dockerfile with a base image of something like FROM node:4-onbuild . Then do a docker build . This will produce an image with your application in it, ready to be run. This strategy is known as the Docker strategy in an OpenShift BuildConfig. Another strategy is using the s2i...

A while ago, I wrote a fairly long post attempting to shed some light on a few things you can do in your JavaScript classes to enforce the concept of data encapsulation - or data "hiding". But as soon as I posted it, I got some flak from a friend who is a Clojure programmer. His first comment about the article was this. Mutability and data encapsulation are fundamentally at odds. Eventually, he walked that back - but only just...

NPM 4 was released recently, about 2 weeks ago, and with it came some major changes. Some breaking, some not, but there is an interesting deprecation that happened with regards to the prepublish script. Currently, if you had a prepublish entry in your package.json: { scripts: { prepublish: "nsp check" } } This would be run whenever you performed a npm publish . Which is probably what you would expect with a name like prepublish. Another thing was also happening...

Node.js 7.0.0 was released just last week, and the announcement dropped a bombshell. I'm guessing the following announcement might freak some people out: DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code. While the UnhandledPromiseRejectionWarning has been in node since 6.6.0 , this deprecation warning is new --- basically, it means you've rejected a promise in your code, but you are not handling it...

For your end users, one of the most important aspects of your API is the perceived response time --- if your mobile application takes an excessive amount of time to load data, users will get frustrated. In this series of blog posts, we’ll cover three ways to approach building a RESTful API that leads to better user experience by minimizing perceived response time. These strategies include: processing requests quickly, reducing payload sizes, and eliminating requests entirely, or only downloading data...

Node.js is a JavaScript runtime built on top of Chrome's V8 JavaScript engine . It is highly event-driven, and leverages non-blocking I/O model that makes it lightweight, efficient, and incredibly productive to use. It's that last bit, "productive", that I want to focus on today. One of the things that i feel makes Node(and NPM) so great is the ease in which you can add and use third-party modules. As most node.js developers know, to start using an external module...

Objective Some days ago, I was having an argument with a few Java developers about Node.js, they asked questions like “why should I use that?” or “what’s the benefit?”, I told them by memory that Node.js is an event driven I/O, and thanks to that you will end up writing very efficient server-side applications. They come back saying that they can get the same effect using threads. Thing is I wasn't fully prepared to explain the difference, I had a...
