Recently, one of my government clients decided to switch their public facing ASP.NET to Drupal (an open source solution), and they had an embarrassing hacking scenario. There are a number of disadvantages to open source systems that you should be aware of before making the switch.
The Boy Scouts have a rule: “Always leave the campground cleaner than you found it.” What if we followed a similar rule in our code: “Always check a module in cleaner than when you checked it out.”
In this post we are going to learn the benefits of Continuous Integration in Software Development. Let’s understand what continuous integration is first and then we will discuss the benefits we are having.
I frequently hear or read people suggesting using User Stories for relatively long-range planning. Sometimes they mean something as short as a release in a few months. Sometimes they’re talking about multiple releases over a year or two. What are the implications for doing this?
NuoDB 2.0 was recently released and it delivers some major new geo-distributed management features, along with database automation and SQL and Java stored procedures. The geo-distribution capabilities enable users to distribute a single logical database across multiple cloud regions or data centers.
I’ve been pushing this branching model for something like 14 years now. It’s nice to see Facebook say a little more about their Trunk Based Development. Of course they’re not doing it because they read anything I wrote, as the practice isn’t mine, it’s been hanging around in the industry for many years, but always as bridesmaid so to speak.
If you’re like me, you may have 30 branches at any given time. This can make viewing all the branches unwieldy. Once I week or so, I would go on a branch deletion spree by manually copying and pasting multiple branch names into a git branch -D statement.
How does your engineering organization build and deliver products to its customers? Similar to the well-known capability maturity model, the maturity level of a build automation system falls into one of the following: chaotic, repeatable, defined, managed, or optimized. Let’s take a look at the differences in these levels.
Another pattern? Well yes. I write unit and integration tests almost every day and along the way I learned all kinds of different tricks and gotchas on how to be more productive and how to write less fragile tests. But one of the patterns that emerged I never saw in the code of other people so I decided to share it here since I find it very useful. I call it Testing ContextPattern and – unlike it’s name – its very simple.
People at their core are loving, nurturing beings. They want to help others and make them feel wanted. In the world of business, keeping these needs in perspective can be challenging.
The term “legacy” has mixed meanings in software development and I am personally trying to remove it from my vocabulary. It often has a bad connotation. Many developers use it to describe code that they did not write and do not like.
One thing that's not allowed anywhere (seemingly) on the StackExchange network is the so-called Shopping Question. I was talking about this in ServerFault Chat recently, and I thought it was about time to have a go at a spin-off site, just for shopping questions. Here it is: TechShoppingAndInfo
I was reading through Oracle’s release notes on Java SE 7 and noticed that they include a new facility for concurrent random numbers.
Yes, it is my opinion, and yes, it might seem like a hate-post. But I’ll try to address the issues I have with Scala and its surroundings.
Loose coupling and high cohesion. Taken individually, both concepts appear sound; taken together, however, they confess worrying inconsistency
One of the basic ideas in DevOps is that developers and operations should share responsibility for designing systems, for implementing them and keeping them running. If you ask whether developers should have access to production you’ll find that people fall into one of 3 camps: (1) Of course! (2) Maybe, sometimes (3) What, are you nuts?
In this presentation, which is embedded below, Mike talks about a devops project he was on in Australia. He and his team were brought in to a large trading firm to implement continuous delivery and integration, they got the code right but made a few critical mistakes. Listen to Mike as he tells his cautionary tale.
Imagine a simple Akka actor system consisting of two parties: MonitoringActor and NetworkActor.
Fortunately for those migrating Ant builds to Gradle builds, Gradle provides particularly convenient mechanisms to facilitate this migration.
One of Git’s selling points, some years ago, was that it has lightweight branching compared tools that came before it. Anyway, it’s Git’s merges that are the truly lightweight thing in my opinion. This article tries to show how that is.
It has been a while since we've migrated from JBoss AS 5 to 7. This article describes problems we have found during the migration process as well as benefits we gained from it.
Jason Leyba spoke at QCon in San Francisco at the end of last year, and Jez Humble snapped a pic of a pertinent slide (I’ve straightened it out a little). Sounds a bit unmanageable right? Not to them, there’s method in the madness, and it’s all optimized for maximum developer throughput while incorporating code reviews, code reuse, and quickest possible CI.
Imagine you have some code that is being fired right before, or during, a click that leads you to another page. If you use the console than you are in luck. Both Chrome and Firefox have options to preserve the console on navigation. In case you've never seen it, here is the option in Chrome. You find this by opening the Dev Tools and clicking the gear icon in the lower right hand corner.
After upgrading from Apache 2.2 to 2.4 in a Windows development environment, all my virtualhosts stopped working. I could add syntax errors to the files which would make Apache refuse to start up, or get notices about invalid document roots, but the virtual host server names just wouldn’t catch on.
In my opinion a deployment of any application should be as automated as possible to avoid errors due to manual mistakes. This is no different with a Mule ESB application. This instrument makes the governance of the deployment of your Mule applications into different environments easier and therefore the whole deployment cycle less error-prone.
