I am a statistician, but I have worked in a department of predominantly econometricians for the past 17 years. It is a little like an Australian visiting the United States. Initially, it seems that we talk the same language, do the same sorts of things, and have a very similar culture. But the longer you stay there, the more you...
Whenever a new networking platform is evaluated, one of the early sales calls includes a packet walkthrough. In excruciating detail, someone walks the customer through the path a packet takes from ingress port, through the device, across the switching or routing ASIC, and back down to the egress port. The technical deep dive frequently includes internals that even the vendor engineers are not all...
I admit: I love command line interfaces. Because that gives me
usually much more control than any GUI (Graphical User Interface). I
like the fact that they have put a UART interface on the RIoT board:
The RIoT board comes with a 3-pin header (Tx, Rx and GND) which gives a console/UART connection to the board. Any kind of...
Build team interest and passion in DevOps by promoting four DevOps themes:
What solution or best practices do you see solving balkanized, silo development tooling, fractured governance, disconnected workflow, and incomplete status reporting when working with distributed outsourced teams or across internal teams?
Rob Napier knows quite a bit about Objective-C, but as evidenced by this recent post, he doesn't know Swift. And more importantly, according to Napier, neither does anybody else - not even Apple.

source platforms such as OpenStack, OpenShift, and Cloud Foundry have
emerged as the best and brightest platforms for networking, data
storage, compute horsepower, and secure distributed infrastructure needs
of enterprises big and small. These tools provide tremendous
You have unexplained production issues from time to time. The business is impacted and the management briefs down your neck while the pieces of the puzzle are collected. There is no way to recreate this on QA set-up. The issue is lurking there for quite a while and becoming more and more frequent. Sounds scarily familiar?
IntroductionThis article will look at
building Glassfish 4.0.1 from source and configuring NetBeans 8.0 to then use,
modify, and debug it. While GlassFish can be downloaded ready for use, even
coming bundled with NetBeans, there will be some among us who need (or just
want) to build it from scratch. This build was conducted using a 64bit Linux
Distro, JDK 1.7.0_55, Maven 3.2.1, and SVN...
Originally by Vadim Tkachenko In my recent post, “TokuDB gotchas: slow INFORMATION_SCHEMA TABLES,”
I saw a couple questions and tweets asking if we use TokuDB in
production. Actually I mentioned it in that post and we also blogged
about it in a couple of other recent posts:
In my recent post, “TokuDB gotchas: slow...

Indexes in Couchbase are a flexible means of performing back end processing. When utilizing indexes it's possible to create decision tree type aggregations and selectivity functionality, such as those found in an inventory control system.
Want another way to debug Cordova/PhoneGap apps? This isn't new, but I
tend to forget about this option and it came in handy yesterday so I
thought I would share. When you send builds to the simulator/device via
the command line, you may notice that at the end of all the output about
building this and generating that, you get these two lines:
In this post we explore 5 reasons to use a Java Data Grid for caching
Java objects in-memory in your applications. In a later post we will
explore some of the other data grid capabilities, beyond data storage,
that can revolutionize your Java architectures, like on-grid computation
In this post we explore 5 reasons...
Testing has always been and will continue to remain the number one priority of web developers engaged in the execution of different types of web development projects. Whether it's about performing manual testing or automated testing, web developers don't delay in spending a good duration of time on ensuring that the site renders a brilliant user experience. Unit and integration testing are great,...

It was rightly pointed out yesterday that it's dangerous to link to lines or blocks of code on Github without explicitly specifying the commit hash in the URL. On this theme, consider this git command:
$ git browse -u -- commit/$(git rev-parse HEAD)
When I was writing post on SpringMVC-Tiles3 integration, I used one controller method index() to just return to index.jsp view. It was very stupid way to write a method to just re-direct it to a view if you don’t have anything to do in controller.
Previously, I used one controller method index() to just return to index.jsp...
In this guest post, Chris Saxon explains a very important topic using an analogy with chocolates: When does a database use an index and when is it better not using it. Although Chris explanation has the Oracle database in mind, the principles apply to other databases too.
A common question that comes up when people start tuning...
A lot has happened in the cloud industry since the release of our 2014 Cloud Platform Research Report in early March, which is why we are providing monthly industry news updates to keep our community truly updated. Here are the major happenings up through July 16th:

In preparation for my talk, Agile Projects, Programs, and Portfolio Management: No Air Quotes Required, I have created a Minimum Reading List for an Agile Transition. Note the emphasis on minimum.
I could have added many more books to this list. But the problem I see is that people don’t read anything. They think they do agile if they say they do agile.
While reading ‘Why The R Programming Language Is Good For Business‘ I came across Udacity’s ‘Data Analysis with R‘ courses – part of which focuses exploring data sets using visualisations, something I haven’t done much of yet.
I thought it’d be interesting to create some visualisations around the times that people...
