There's a Math library for OneNote and Word!

I use OneNote as my virtual notepad.  I love being able to have my notes in whatever type of office doc, pdf, etc. sync'd and available in my SkyDrive.

I recently had an issue with math notes that caused Mathematica1 font to display as a unknown character (small rectangle which is the default character when an app cannot find the font) as seen in here. 

I resolved the font issue by using Mathematica1Mono instead (bottom of graphic), however the beneficial positive outcome of this issue lies in my stumbling upon a Math library for OneNote and Word 2013 in my search for a resolution.
(There is also a 2010 version) with these wonderful features:
  • Compute standard mathematical functions, such as roots and logarithms.
  • Compute trigonometric functions, such as sine and cosine.
  • Find derivatives and integrals, limits, and sums and products of series.
  • Perform matrix operations, such as inverses, addition, and multiplication.
  • Perform operations on complex numbers.
  • Plot 2-D graphs in Cartesian and polar coordinates.
  • Plot 3-D graphs in Cartesian, cylindrical, and spherical coordinates.
  • Solve equations and inequalities.
  • Calculate statistical functions, such as mode and variance, on lists of numbers.
  • Factor polynomials or integers.
  • Simplify or expand algebraic expressions.

A new version of .NET or Data Quality Services was installed on this machine. In order to continue to work with DQS please run 'DqsInstaller.exe -upgrade'

I recently tried to use Data Quality Services 2012 and as a result of my having applied service packs / Cumulative updates / hotfixes, etc. to my dev box, I got this error on launch of DQS:
A new version of .NET or Data Quality Services was installed on this machine. In order to continue to work with DQS please run 'DqsInstaller.exe -upgrade'.

That would be fine, if it actually worked like that.  Unfortunately, even after running this and being told I need to restart, restarting, running it again and restarting again, when I launch DQS, I got the new and improved message:

A new version of .NET or Data Quality Services was installed on this machine. In order to continue to work with DQS please run 'DqsInstaller.exe -upgrade'.
OK...I thought I had better try getting some help on the dqsinstaller and see if that leads to anything...

dqsinstaller.exe /?

usage DqsInstaller.exe [-install | -uninstall | -upgrade |-upgradedlls | -exportkbs | -importkbs] [] [-collation] |[-instance] 'instance name'

-install   - Install Data Quality Services in the provided instance. (Default)
-uninstall - Uninstall Data Quality Services from the provided instance.
-upgrade  - Upgrade Data Quality Services for the provided instance, to current version.
-upgradedlls - Install Data Quality Services while skipping recreating the DQS databases and only upgrade DQS DLLs.
-exportkbs - Export all server knowledgebases.
-importkbs - Import knowledgebases file to server.
-collation - The collation of DB catalogs to install. The collation should be case insensitive.
 - The .dqsb filename used to import/export server backup data.
-instance - Specify the SQL Server instance name that this installer will run against.
-? - Show this usage message.

When catalog collation is not specified the default collation being used is SQL_Latin1_General_CP1_CI_AS.

List of Windows and SQL Server collations can be found at

Press any key to continue...

And this sounded like it might fit the bill:

dqsinstaller.exe -upgradedlls
Wallah, all fixed!  Hope this helps if you have a similar issue.
Heads up - you will need to be a member of the fixed server admin role on the SQL Server instance where the Data Quality Database is installed.

Oracle BI Repository Identity Manager shows no users

Q:  When in the Oracle Business Intelligence (OBIEE) Administration Tool (Online) and I open the Identity Manager (Manage->Identity), I select BI Repository and though the roles exist, I see no users.  How can I see them?

A: Select Action from the toolbar, then in the textbox for Specify Wildchar filter to fetch users, use an asterisk.

ORA-01034 and ORA-27101 on WIndows machines

Subtitle: Overthinking the problem

Every site on the net which references these two errors:


ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist

seems to suggest that they are symptoms of either the ORACLE_SID not being set correctly or the ORACLE_HOME not being set correctly. Beyond that, they recommend checking the alert log to see if, possibly, there is some more serious problem with the database.I recently encountered these errors on a database whose windows service had started successfully. On a server with the ORACLE_SID and ORACLE_HOME set correctly; with an alert log which had no errors.

I have a simple solution to these two errors which does not involve any of these recommended approaches.

Check to ensure the database is started ;-$ FML

CI Setup part 2

BerliOS uses an old version of subversion (1.2) which may explain my inability to set it up with TortoiseSVN. In any case, I found a much faster, more up to date, and richer host for my Subversion server at Setup was a breeze, soup to nuts in about 15 minutes and there were no problems integrating with TortoiseSVN. In fact, they offer instructions on integrating with 9 other products (including Twitter).
Next: Building my CIFactory script...
