I’ve created an unofficial version of an ActivityPub OWL ontology for experimentation and exploration purposes. It’s based on an old Activity Streams ontology that was abandoned in favor of JSON-LD in ActivityPub. I also created a separate ontology for Mastodon (toot) extensions. The ontology is represented in the RDF Turtle format. It can be viewed and browsed in tools like Protégé. You can find the … Read more

It’s been 11 years since I wrote about the notion of being “Agile” without a name. My feelings about the topic haven’t changed since then. I still believe it’s more important to be an effective software developer than one that has been labeled “agile” according to some specific agile methodology. The Agile Manifesto suggests valuing “Individuals and interactions over processes … Read more

There was an interesting discussion during the Agile Toolkit Podcast interview with Dave of the Pragmatic Programmers. I’ve transcribed a few of the comments about agile methodologies below. Dave Thomas: I think agile methodologies have adopted their own venom. And to that extent, I’m pulling back, away from, the individual agile methodologies. I believe very, very strongly in agility. … Read more

One particularly interesting challenge was discussed by Dan Pritchett, Technical Fellow at eBay, Inc. He spoke about the challenges of providing enough power and air conditioning to eBay’s data centers. I’m not sure how accurate … Read more

Apparently, APM tools are being widely used by both small and large organizations although the primary reasons differ with the size of the organization. It was interesting to me to see that card-based approaches are used less often than dedicated APM … Read more
In a recent article I wrote about preferring Effective Software Development (ESD). I prefer being effective over being labeled as “agile” (whatever that might mean to you personally). This preference raises many questions for me. How do I define effectiveness? How do I know if I’m being effective or not? How can I become more effective? Is … Read more
A new pair programming study (Arisholm et al. 2007) indicates that that the practice neither increases quality or reduces costs, in general. The results of this experiment do not support the hypotheses that pair programming in general reduces the time required to solve the tasks correctly or increases the proportion of correct solutions. On the … Read more
