While new Freescale boards come with the OpenSDA debug firmware, I still students using boards with the OSBDM/OSJTAG. And with new CodeWarrior tools, it might be that there is a new OSBDM/OSJTAG firmware, and when I download to a board with an older firmware, the tool will prompt me to update the firmware.

People have been wondering about the value of Test-Driven Development (TDD) for a long while, but it was not until David Heinemeier Hansson of 37 Signals  posted a blog article on St.

When working with curl, it can give lots of excellent and detailed information, but sometimes it is too much! Today I’m fiddling with the caching headers on a client’s application, so I’m only interested in seeing the headers and not the body of the response. Making a HEAD request changes the output I get, so I really do want to GET and then only see the headers.

While the bulk of the networking industry’s focus is on CapEx and automation, the two major trends driving changes in these areas will have a potentially greater impact on that which matters most: availability. In fact, despite that datacenter purchasing decisions skew towards CapEx, the number one requirement for most datacenters is uptime.

If availability is so important, why is it not the…

As a self-taught programmer, the most inspirational book for me in my early years, what really made me want to be a coder and never look back, was Steven Levy’s Hackers: Heroes of the Computer Revolution.

At some point, a software project will grow beyond its original scope. In many cases, some portions of the project become their own mini world. For maintenance purposes, it is often beneficial to separate them into their own projects. Furthermore, the commit history for the extracted project should not be lost. With Git, this can be achieved using git-subtree.

In a previous post, I wrote about the incremental nature of innovation, particularly in the networking space. My point was that innovation (both from a product and a deployment perspective) occurs from a frame of reference. Understanding that foundation is critical to determining strategies, especially around go-to-market and adoption.

Many online demos show small AngularJS apps that are easy to
troubleshoot because you can practically memorize the code when the
examples are so small. In the real world you may face complex
applications that contain literally dozens of controllers, services, and
other components. Tracing a problem to the appropriate source code can
become more challenging. In this video I’ll show you how to…

 Here’s a little demo video that I put together to explain
pushing/pulling with multiple remotes and how tracking branches make
this easier. It’s one of the chapters from my “Git Adventures” talk,
but it didn’t make it in to the talk in Amsterdam last week since we
chose a different adventure that time – sharing it here in case it’s
helpful to anyone else, and so I can find it later!

Which is more readable?releaseVersion = version.substring(0, version.indexOf(‘-SNAPSHOT’))

orreleaseVersion = version[0..-10]

Given a value of 0.109-SNAPSHOT for version, they both give the same result. And I’m tempted by the second, because it’s shorter. But I’m going to go with the first one – not because it’s more Java-ish and I’m scared of Groovy syntax, but because it’s…

To separate logic of accessing data from the routes, we create separate modules to handle the task of data access. When I started learning Node.js, a common pattern that I saw in some samples to separate the data access logic from routing was as follows:
