Use the Lotus Symphony sidebar in Libreoffice
Thu, Apr 17th 2014 5:14a   Ralf Petter
One of my favorite features in Lotus Symphony was the sidebar. On today's wide screens a classic toolbar or the ribbons in Microsoft Office on top of the document does not make sense, especially in a Text processor where the documents are in portrait format. A sidebar as in symphony uses the screen space much more efficiently. The sad thing is that IBM has abandoned Lotus Symphony, but fortunately IBM has open sourced their changes to the Openoffice codebase. So i can use my favorite feature in [read] Keywords: ibm lotus symphony microsoft office openoffice wiki

Windows memory management explained in Detail
Tue, Apr 15th 2014 4:47a   Ralf Petter
There are so many myths about memory management in windows. Often people use the task manager to show that program X is a resource hog, because it is eating too much main memory. But most time they are using the wrong columns and make wrong assumptions whats going on. Analyzing memory problems on windows needs a deep understanding how memory management in windows works and which tools you can use to find problems.

The developerworks site for IBM Collaboration Solutions software (aka notes.net) got a new design. In my opinion the design does not look bad, but it is very difficult to find things on the new site. For example i cannot find the fixlist database anymore.So IBM thank you very much for the new design, but please add easy to find links to such important resources like the FixList database, the forums or the red wikis.

Improve SQL grouping performance with Db2 EVIs
Wed, Mar 19th 2014 1:12p   Ralf Petter
In many SQL queries the "GROUP BY" clause is used to aggregate some values. For example a manager wants to see sales for a specific year grouped by region. The SQL for this query looks like this: SELECT REGION, SUM(AMOUNT) FROM INVOICES WHERE YEAR=2013 GROUP BY REGION The Db2 optimizer implements the query with a table scan and a temporary hash table. The runtime of the query is on our 4 Core box with SSDs and 64 GB main memory 620 ms, which is pretty slow for such a simple query. Fortunate [read] Keywords: ibm db2 sql

Sun, Mar 16th 2014 6:13a   Ralf Petter
If you are still using DDS and record level access in your "IBM i" applications you are missing most of the enhancements IBM has provided for "IBM i" since V5R1. While DDS and record level access are still supported and there are statements of directions that they will be supported in the future every "IBM i" Developer should really plan to migrate their applications from DDS to SQL. This migration is really very easy to do because it is more an evolution than a revolution. You can access [read] Keywords: ibm application applications db2 sql
