Arbitrary value store (registry) for ABAP

May 20th, 2015

One of the problems ABAP developers face from time to time is the need to store arbitrary values for processing. These values do not always justify creating a new table, and there is no convenient place to store such values.

Yet another ABAP JSON parser – and some other stuff

March 27th, 2015

We have had the capability to process JSON in ABAP for some time now (refer to this blog post for an introduction).

SAP Business Intelligence with Elasticseach and Kibana

February 20th, 2015

After having played around with Elasticsearch for indexing PI payloads and indexing ABAP source code, and especially after seeing the new (and now just-released) Kibana 4, it occurred to me that Elasticsearch would actually be great for business intelligence reporting.

SAP PI message payload search using Elasticsearch

August 26th, 2014

At our client we recently went live with a solution that incorporates SAP PI. At the time we did not have TREX set up to be able to perform searches on messages. (And at the time of writing we still don’t, but we should have it soon). ┬áSo as a stopgap measure, I developed a solution that uses Elasticsearch to index payloads and allows you to search them.

Taking a new look at REBOL

June 18th, 2014

The other day I was on StackOverflow and an open source ad on the sidebar caught my attention with the words: “help us build the first full-stack Language” and “RED”. “Well,” I thought, “this is rather intriguing.”, so I clicked down the rabbit hole.

Forwarding local AJAX requests to an SAP ABAP server with Nginx

November 22nd, 2013

I am busy doing a little proof-of-concept solution to produce a mobile app using a BSP application as a container. In concept, this sounds easy, but there are always snags that slow down the development process, particularly trying to test AJAX calls to a remote server from a locally hosted app.

Getting started with SAPUI5

November 18th, 2013

A while back I had the opportunity to investigate SAPUI5 as an option for user interfaces on our current project. Here is a quick little getting started guide that I wrote back then, partly for my own benefit in case I ever need to get started on it again.

Classy headings in your code with ASCII art

November 1st, 2013

Sometimes source code modules get very big. You can argue that this should never be the case, if you modularize your code properly, but the fact is that they do. And when they do, they sometimes become difficult to read. Read the rest of this entry »

The road to Lisp

April 11th, 2013

One of the hurdles I face in learning a new language, as you probably do too, is that I am always looking at it from the point of view of my current context, more specifically the current set of languages, and in particular, my favorite language, which is Ruby.
