Introduction These days I spend a lot of time in the bash shell. I use it for ad-hoc scripting or driving several Linux boxes. In my current project we set up a continuous delivery environment and migrate code onto it. I lift code from CVS to SVN, mavenize Ant builds and funnel artifacts into Nexus. […]
Ansible – next generation configuration management
The popularity of the cloud has taken configuration management to the next level. Tools that help system administrators and developers configure and manage large amounts of servers, like Chef and Puppet, have popped up everywhere. Ansible is the next generation configuration management. Ansible can be used to excute tasks on remote computers via SSH so […]
QCon London 2013 – Agile in Actuality, Open Data, Latin as a Programming Language
After an exciting few days at the QCon conference in London last week, I am slowly recovering from all the new input I got, and decided to do this by writing a little summary of “all things agile” from the Thursday as well as the highlights the other two days too. Cherry Picking Wednesday On […]
Authenticating Dutch organizations via eHerkenning
Introduction In The Netherlands, citizens can interact with digital government services using a central username and password through an authentication scheme called DigiD. This helps these services to hook into a central registry of users, thus providing them with a single identity corresponding to a single username and password. DigiD is a widely spread and […]
Beyond classical contracting
There is an interesting approach from the German IT service provider Adesso AG and the Ruhr Institute for Software Technology on how to balance project risks between service providers and their customers within a new contracting model, which is a combination of fixed price and Time & Material approaches.

A captive portal turns a Web browser into an authentication device. This is done by intercepting all packets, regardless of address or […]

A front-end developer surrounded by a horde of scary “Enterprise Java” developers?
Orange11 is urgently looking for an accomplished front-end developer. We’re looking for a person that obviously has extensive experience using HTML5, Javascript and CSS3. But, more importantly, we’re looking for a developer that really has an opinion to share; about most things really; but certainly on how to build high quality, maintainable applications (which patterns, frameworks, etc) […]
JVM memory management and performance tuning
Performance and scalability are important topics for most enterprise applications that we build. Oftentimes we mostly consider connections to external systems (databases, message brokers, external web services) when we think about performance bottlenecks or performance and scalability optimization. This makes sense, as most enterprise applications spend a lot of their time performing (typically blocking) I/O. […]
