Allez, rendez-vous à Paris – An AWS Region is coming to France!

All Things Distributed

Today, I am very excited to announce our plans to open a new AWS Region in France! Based in the Paris area, the region will provide even lower latency and will allow users who want to store their content in datacenters in France to easily do so. The new region in France will be ready for customers to use in 2017. Over the past 10 years, we have seen tremendous growth at AWS.

How to Load Balance RESTful Web Services Using CXF and Apache Camel

DZone

In this article I am going to show you two approaches to load balance JAXRS web services without an Apache or a hardware load balancer. The full code is available on GitHub. CXF provides clustering strategies which can be used for configuring a load balancer which has already been discussed here. However, load balancing the JAXRS requires a little more effort, which I have described in this article.

Connect to a Raspberry Pi Zero with a USB Cable and SSH

The Polyglot Developer

As some of you may know, I have a hoarding problem. I am hoarding Raspberry Pi microcomputers. In my personal collection I have one from each generation, making four standard units. Well, I recently picked up another unit, but this time a Raspberry Pi Zero. These things are about the size of a nine volt battery, but pack some serious punch. The problem is they are incredibly rare because they retail for only $5.00.

What Makes A Senior Software Developer?

Professor Beekums

UPDATE 2017-01-01: This post has a follow up. Most engineering organizations will have to answer the question: “What makes a software developer a senior developer?” This is a challenging question because it is extremely subjective. Search for the answer on the internet and you will get many different answers. Some will contain criteria that are also subjective themselves which adds additional difficulty to the question.

CPP: A Standardized Alternative to AMP

Tim Kadlec

It’s no secret that I have reservations about Google’s AMP project in its current form. I do want to make it clear, though, that what bothers me has never been the technical side of things—AMP as a performance framework. The community working on AMP is doing good work to make a performant baseline. As with any framework, there are decisions I agree with and some I don’t, but that doesn’t mean the work isn’t solid—it just means we have different ways of approaching building for the web.

PWA Performance

Speed Curve

Progressive Web Apps (PWAs) combine the best and newest features of the Web to deliver an experience that rivals native applications on mobile. Even better, they work on desktop, too. In fact, they work everywhere that the Web works! "Ah", you say, "that's not true! They require features that don't exist in all browsers." Because PWAs are "progressive", they can adapt to older browsers to deliver the best experience possible given the features that are available.

What's in a Word?

Nick Desaulniers

Recently, there some was some confusion between myself and a coworker over the definition of a “word.” I’m currently working on a blog post about data alignment and figured it would be good to clarify some things now, that we can refer to later. Having studied computer engineering and being quite fond of processor design, when I think of a “word,” I think of the number of bits wide a processor’s general purpose registers are (aka word size ).

What is User Acceptance Testing?

The software development life cycle is complex. Among the many moving pieces of developing software is the process of testing. Testing ensures quality in the product and proves the code is functioning as expected and as needed. There are many different testing activities that should occur within the process of building software. User Acceptance Testing, or UAT, is just one of the various types of testing involved in the software development life cycle, and most commonly, it is the final testing

Converting Your Ionic 2 Mobile App To NativeScript

As many of you know, I had been using Apache Cordova based frameworks such as Ionic Framework for a long time. They are convenient and easy to use when it comes to rapidly developing cross platform applications. The problem with using Apache Cordova frameworks such as PhoneGap, Ionic Framework and Onsen UI is the performance limitations that come with them, particularly because of their use of the platform web view.

Beware of Developers Who Do Negative Work

Chasing Tools

The developers were overworked and the site had never gotten enough budget to give it the rebuild it needed.

Data Models and Word Size

Nick Desaulniers

This post is a follow up to my previous blog post about word size. Three C/C++ programmers walk into a bar. One argues that sizeof(void*) is equivalent to sizeof(long), one argues that sizeof(void*) is equivalent to sizeof(int), and the third argues it’s sizeof(long long). Simultaneously, they’re all right, but they’re also all wrong (and need a lesson about portable C code).

What is the difference between black box and white box testing?

Both types of testing are vital in producing quality software, but the difference is the approach to these testing methods is considerable.
