What is it about? Last year I wrote a nice set of scripts on installing Fusion Middleware and creating Fusion Middleware Weblogic domains.
I created the domain-creation-script (more...)

R is a great piece of software to perform statistical analyses. Computing power can however be a limitation. R by default uses only a single CPU. In almost every machine, multiple CPUs are present, so why not utilize them? In this blog post I’ll give a minimal example and some code snippets to help make more complex examples work.
Luckily using multiple CPUs in R is relatively simple. There is a deprecated (more...)
So here it is:
Oracle announces a license audit, some urgency kicks in and this familiar but also really serious question comes up from management: “Are we using any unlicensed database features“. The seriousness is quite understandable, because if so, the company can look forward to some negotiations with Oracle over license fees, possibly resulting in considerable and unforeseen extra costs.
To be able to provide a swift and correct answer (more...)

As an integration/backend developer, when starting a project using Mobile Cloud Service, it is important to have some understanding of what this MBaaS (Mobile Backend as a Service) has to offer in terms of security features. This is important in order to be able to configure and test MCS. In this blog I will give examples on how to configure and use the basic authentication and OAuth2 features which are provided to secure APIs. You (more...)
According to Gartner, machine learning is on top of the hype cycle at the peak of inflated expectations. There is a lot of misunderstanding about what machine learning actually is and what it can be done with it.
Machine learning is not as abstract as one might think. If you want to get value out of known data and do predictions for unknown data, the most important challenge is asking the right questions and (more...)
In the first part of this series I introduced the concept of Developer Experience and why I think it is important that we start investing more into improving the Developer Experience. In this part I will lay down some foundations on how this could be done.
Not all developers are alike. You can see this within a company like Oracle: developers in the DataBase group (more...)
For the past 2 years I have been trying to raise awareness of the concept of Developer Experience (DX) both inside and outside Oracle. Over the next few days I will release a couple of blog posts delving deeper into this subject. This first post will concentrate on what DX is and why I feel it is important that we invest in it.
The concept of Developer Experience has existed for many years. (more...)
Last week at our company we organized a session about NoSQL in general and MongoDB in particular, as you can read here. The MongoDB focus was presented by me and I would like to take you with me on my trip to actually appreciating the NoSQL database world (and MongoDB in particular).
Coming from RDBMS I’m used to ACID. Business models reside within the database, data never gets lost, transactions are isolated, you’ve got your (more...)
I have just returned home from the Oracle PaaS Partner Community Forum 2017 which took place in Split, Croatia. Filled with energy, inspiration, impressions, already fond memories, more understanding, longer term plans and shorter term action items and a warm feeling of being part of an international network of smart, open, helpful and fun people. Does that sound soft, a little over the top – slightly brainwashed even? Let me try to explain what this (more...)
In my previous entry, Fun with Facebook, I described how to pull data from Facebook’s Graph API Explorer, organize it using NodeBox, and turn it into representations of friends, posts, and the “likes” that connect them. Here is the final result:
The above image is a snapshot of a high-resolution poster with many fine details. One of my goals for this project was to create (more...)
In my previous blog I’ve explained what a Canonical Data Model (CDM) is and why you should use it. This blog is about how to do this. I will share my experiences on how to create and use a CDM. I gained these experiences at several projects, small ones, and large ones. All of these experiences were related to an XML based CDM. This blog consists of three parts. This blogpost contains part I: (more...)
This blog is about XML namespace standards. Primary for using them in a Canonical Data Model (CDM), but also interesting for anyone who has to define XML data by creating XML Schema files (XSD). This blogpost is the second part of a trilogy about my experiences in using and developing a CDM. The first blogpost is about naming & structure standards and the third blogpost is about dependency management & interface tailoring.
This blogpost is part III, the last part of a trilogy on how to create and use a Canonical Data Model (CDM). The first blogpost contains part I in which I share my experiences in developing a CDM and provide you with lots of standards and guidelines for creating a CDM. The second part is all about XML Namespace Standards. This part is about usage of a CDM in the integration layer, thus how (more...)
