SAP NetWeaver is one of a cool and complete platform for large-scale enterprise backoffice. There are so many components especially in the recent version which Java development is mainstream. That's why SAP has to distribute Technology Preview to anyone interesting to learn by themselves for wide-range users, e.g., administrator, developer, manager and etc. Another benefit is to test the product world-wide as a beta test so that all testers will generate bug reports to the community.

Anyway, all previews are not the real products and there is no professional support. We have to learn how to solve issues ourselves. I just got one issue during trying test Design Time Repository for large-scale development team. The problem occurred when I tried to import development configuration in NWDS.

Import configuration failed:Could not create mountpoint for SC in compartment example.org_APPL_1: Could not create remote path /dtr/ws/Application/example.org_APPL/dev/inactive/SCs/example.org/APPL/_comp/TopLevelDCs/ (Internal Server Error).

According to the question and my snippets, the same one asked me again to extend the previous codes to show the author's name besides the node title. In addition, it would be nice to display node title and its author in a table form. Fortunately, this is Drupal. It is very easy.

I found an interesting question regarding Drupal at Codenone. One would like to list the latest 11-20 nodes in a block. He tried to use Views module with no luck. I think so. Listing the latest nodes in a block using Views is very easy but I don't see any clue to get the next 10 nodes. Anyway, it is possible to write a snippet code to fulfill this requirement.

I was asked to help implement a kind of reusable combination generator in Python given the maximum number and the group size. Combination is widely used in high performance computing especially for searching in state space. Note that it means solving problem by brute force technique. So I wrote several codes.

I found a good question at Codenone regarding author's full name in Drupal. This is a good question because it clearly shows the power of Drupal. If you notice, all contents in Drupal will show their authors somewhere in the page. An author is identified by his/her username. And there is no full name stored in the database by default. Other CMSs usually store user's full name in its database so you might think Drupal is worse. In fact, you are allowed to add additional metadata using profile module which is included in the core modules. So showing author's full name in each node is very easy.
