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.

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.

Building your applications with only managed components has become very popular, and AWS Lambda plays a crucial role in that. I see a tremendous interest in examples how to build such applications, and articles such as " The Serverless Start-Up - Down With Servers! " about teletext.io are read eagerly around the globe. If you are looking for more examples there are the Lambda Serverless Reference Architectures that can serve as the blueprint for building your own serverless applications.

If you’re a long time follower of my blog you’ll remember I wrote an article about creating an RSS reader using Ionic Framework. That tutorial not only used the first version of Ionic Framework, but it now also uses a deprecated Google service, once known as the Google Feed API. Because of the deprecated API, it no longer works. I still get a lot of people asking me about the creation of RSS readers, so I figured it was time to come up with a new solution.

Let’s say you want to build a hello world command line application in C or C++ and run it on your Android phone. How would you go about it? It’s not super practical; apps visible and distributable to end users must use the framework (AFAIK), but for folks looking to get into developing on ARM it’s likely they have an ARM device in their pocket. This post is for folks who typically invoke their compiler from the command line, either explicitly, from build scripts, or other forms of automation.

A few years ago, I wrote about the chronic misuse of the word "governance" in technology. The word "portfolio" is suffering the same fate. The reason for introducing the word "portfolio" into tech management is that some portion of tech spend is really an investment in the business, something that differentiates it and gives it a competitive edge - for example, mobile or web client-facing apps, or internal software that codifies workflows to capture efficiencies.

The subject of technical debt comes up often in software development. It is better to have something done sooner rather than later from the perspective of the project. Yet, this assumes all things are equal, which is rarely the case. Often a developer will have a choice: the short term path or the long term path. For example, a task can be done in 2 hours with one implementation.

PouchDB is one of a few good solutions that makes this task significantly easier.

So you’ve released this great application that you developed using NativeScript by Progress. The problem you might be facing now is that no one is rating or reviewing your mobile application. This may be related to the fact that it takes a bit of time to find an app in the app store and then leave a rating. A great solution to this is to prompt the user to rate your application and be automatically redirected to the app store listing should they agree to leave you a rating.

I’ve created a few tutorials around Ionic 2 while it was in its early alpha stage up until now. These tutorials explain how to use the bits and pieces that the framework or Angular offers, but I never demonstrated how to make a functional application. Seeing how to put the pieces together makes a huge difference when learning a new technology. We’re going to see how to build a simple todo list type Android and iOS application using Ionic 2, Angular , and TypeScript.

When developing an Ionic 2 application there are often scenarios where it probably isn’t a good idea to include repetitive source code in multiple application pages. A common example of this would be when it comes to database interaction in an Ionic 2 application. Sure you could establish a connection to the database on every page and query it, but it would probably make more sense to use it like a shared provider.

Various changes from automatic soft NUMA to CMemThread partitioning have muddied the water around the trace flag –T8048 messaging. Prior to SQL Server 2016 the trace flag –T8048 is used to upgrade (only) NUMA partitioned, CMemThread objects to CPU partitioned based objects. A few of the most common CMemThread objects have been upgraded to NUMA partitioning, allowing –T8048 to be used as needed for additional partitioning.

Internally DBCC CHECK* uses a page scanning coordinator design (MultiObjectScanner.)
