OSGi, Maven and Building Domino p2 Update Sites

**SHAMELESS PLUG:** With me moving to HCL next month, it’s always important to ensure there is sufficient resiliency in the development teams of open source projects. There are always areas where OpenNTF Domino API may be of benefit, but there will be projects I’m involved in where it won’t. There will also be a big …

Understanding Pub Sub

One of the big amendments in Domino V11 is pub sub. It brings a lot of potential, but only with the proper understanding of how to leverage it. It’s a concept many Domino developers may be unfamiliar with, but one that has a lot of parallels in web development. In Vert.x there is the Event …

Thoughts on the Problem of XPages

Jesse Gallagher posted a thoughtful blog about the challenges for the way forward with XPages. It’s a challenge I’ve had a number of discussions around, many of which are ongoing. The reason there’s not a simple solution – throw whatever resources are required into XPages – is that it simply doesn’t make business sense. There …
