Welcome to part 4 of Red Hat JBoss Data Virtualization (JDV) running on OpenShift. JDV is a lean, virtual data integration solution that unlocks trapped data and delivers it as easily consumable, unified, and actionable information. JDV makes data spread across physically diverse systems such as multiple databases, XML files, and Hadoop systems appear as a set of tables in a local database.

"Everything fails, all the time." A humble computer scientist once said. With all the resources we have today, it is easier for us to achieve fault-tolerance than it was many decades ago when computers began playing a role in critical systems such as health care, air traffic control and financial market systems. In the early days, the thinking was to use a hardware approach to achieve fault-tolerance.

The first day of the first ever Google AMP conference was today in New York. I would have loved to have been able to participate, but I had to settle for listening to bits and pieces from afar (thanks to Google for always doing such a good job of live streaming all of their events). The only session I circled back to watch in its entirety so far was the panel about “AMP & The Web Platform.

Over the past few weeks I’ve been doing a lot of investigation into JSON Web Tokens (JWT) for authentication in APIs. If you’ve been keeping up, you’ll remember I wrote about JWT authentication in a Node.js application as well as building a client facing NativeScript and Angular mobile application that made use of the Node.js backend. This is great, but what if you’re not very fond of JavaScript development?

I’ve written about performing interviews for developers. There is way too much focus on developers improving their “interviewing skills” and not enough on interviewers doing a better job themselves. One of the problems interviewers have is they ask candidates to solve classic computer science problems. I did this when i first started interviewing. It made sense because it was what everyone else did.

Today’s composite applications can have hundreds of failure points (memory leaks, socket exceptions, open connections) all compounded when third-party services and APIs are thrown into the mix — not to mention the added complexity of when the request has to make it through the spaghetti mess of a complex ESB to a legacy system or database in the back end that is never available for testing.

You may be familiar with the saying “ If you can’t measure it, you can’t improve it ”. This saying couldn’t be more true when it comes to web performance. In our browsers today, we already have great APIs such as Navigation Timing and Resource Timing built-in, which allow us to measure the front end performance of our websites. While these APIs provide us with the ability to measure front end performance, they don’t give us any insight as to what is happening behind the scenes - how are requests

Ever found yourself working with comma separated value (CSV) data from a file or other source? This format is easy to generate if you’re working with spreadsheet applications like Google Sheets or Microsoft Excel, and RDBMS applications. So how do we load this data and work with it in an application? More specifically an application built with the Go programming language?

Job hopping is not considered an admirable trait, at least by employers. There is not much for them to like about a developer that leaves after a short tenure. Hiring people is an expensive process since it requires the expense of recruiters as well as time spent by the existing development team for interviews. Time spent in interviews is time that could be spent building software.

Price is the critical determining factor in purchasing decisions. If I want a new case for my tablet, and I know the case that I want, it's worth a considerable amount of my time to find the lowest price on offer for that case. A penny saved and all that. Utility purchases are driven by price sensitivity. If I can't really say one product is a premium offering to another, I'll go cheap at the sales.

More and more we see stories appearing, like this one in HBR by MIT Media Lab's Joi Ito and crew. It praises the power of blockchain as a disruptive technology, on par with how "the internet" changed everything. I am always surprised to see that these far-reaching predictions are made, without diving into the technology itself. This weekend I would like to read about some of the technologies that predate blockchain, as they are its fundamental building blocks.

As pointed out in my previous post, debugging on Linux brings a few new twists to those of us used to the Windows debugging landscape. One of these twists is the need to produce a core dump. On Linux a common way to capture a dump is to generate a core dump ( gcore , etc.). You may have experienced an application crash and the user mode, dump capture on Windows.

Gitlab had a very public outage last month. Most companies provide some kind of explanation when their services are interrupted. Those are usually sanitized (or seem sanitized) to make things seem better than they actually are. Gitlab instead provided an extremely detailed report of the incident as well as all the things they know they could be better at.

In the past few years, we have seen an explosion in the use of Deep Learning as its software platforms mature and the supporting hardware, especially GPUs with larger memories, become widely available. Even though this is a recent development, Deep Learning has deep historical roots, tracing back all the way to the sixties, or maybe even earlier. By reading up on its history, we get a better understanding of the current state of the art of Deep Learning algorithms and the Neural Networks that yo

Recently I taught my daughters some extremely basic cryptography, and it was a great reminder of how critical it is for security to be usable. There are some great ciphers I could have taught them, but they’re still little, so I started simple. I them the rail fence cipher (some may know it as a zigzag cipher which is probably a better description).

If you haven’t already gotten involved with it, you’ll probably know that TypeScript is becoming increasingly popular. Being able to use a superset of JavaScript in a typed language that compiles down to JavaScript is a great thing. However, if you’ve ever played around with TypeScript and tried to use JavaScript libraries, you’ll probably know that sometimes it can be a real pain.

A developer’s job isn’t exclusively writing code. The job is to build systems that bring value to the business. Often times that means choosing to use software written by third parties instead of writing the code from scratch. Whether the option is to purchase a proprietary solution or using an open source one, the situation is the same: the software you are building is now reliant on a third party.

Any mobile application that accesses remote data will need authentication at some point in time. There are many different authentication strategies out there, one of which is with Json Web Tokens (JWT) that we explored in one of my previous Node.js articles. With JWT, users can authenticate via username and password, receive a signed token back, and use that token for any future API request rather than continuing to distribute the username and password.

While I don’t see a lot of it anymore, XML is still a common data format that people use. I prefer JSON, but I don’t always have a say in how I receive data. Some time ago I wrote a few tutorials on which include parsing XML data with Node.js , parsing XML data with Java , and parsing XML data with PHP. If you’ve been keeping up, I’ve been doing a lot of development with the Go programming language which is why I think it would be a great idea to go over XML in Golang.

When building mobile applications you’ll often find yourself needing to create child components. What do I mean by child components? Take for example a mobile application with two different screen groupings, one where the user is not signed in and the other where the user is signed in. In each of these groupings you could have multiple screens where the user is signed in and multiple screens where the user is not signed in.
