MySQL WorkBench 5.2.29 CE - Windows MSI Installer Error

When installing MySQL WorkBench 5.2.29 CE using the Windows MSI installer (mysql-workbench-gpl-5.2.29-win32.msi), I got an error "Error: 25580 - cannot connect to windows firewall".

I followed the instructions from MySQL Forums, and it fixed the installation error. The solution is to start the "Windows Firewall/Internet Connection Sharing" from windows services (Run>services.msc). If the service is disabled, right click and make the start type manual/automatic and then start it.

Disclaimer: I often run into issues either configuring/installing applications on Windows/Ubuntu Linux/Mac OS X. I will hence forth put all the solutions on this blog, so I can use these whenever I need them. I must humbly acknowledge that the credit to most or even all of them would go to all the developers who post their solutions on the net. I will obviously put a link to the original resource.

MySQL 5.5.6 on Mac OS X Snow Leopard 10.6 PreferencePane

PreferencePane for MySQL 5.5.6. seems to have broken "again" in mysql-5.5.6-rc-osx10.6-x86_6.

If you try to start MySQL server using the preference pane it fails. I tried to start it using '/usr/local/mysql/bin/mysqld start' and it still failed.

Here is the fix for the preference pane start and stop.
Edit '/usr/local/mysql/support-files/mysql.server'
Find line 'basedir=.' and replace it with 'basedir=/usr/local/mysql'
Here is the screenshot after the change:

After this, I was able to successfully execute the following commands:

sudo /usr/local/mysql/support-files/mysql.server start|stop

SystemPreferences > PreferencePane > MySQL Start|Stop Server

This fix came from: http://bugs.mysql.com/bug.php?id=53232

Google Books

The entire legal definition of "copyrights" gets thrown out of the window, if you allow anybody to "copy your work" and "make it available" to other people. Unless, of course, the copyright owner expressly allows this or gets a share of the dough.

In the light of Google Books, I humbly pose a few questions:
1. What if I use copyrighted material and gain revenue by not selling the material itself, but by advertisement?
2. Does the copyright owner get any money? And how does the copyright law addresses this situation.

If Google allows authors/publishers to get money generated through such advertisement it might actually benefit these copyright owners. Consumers, might be benefited too, having access to some sample chapters and perhaps the advertisements themselves offering either the sell of such material or anything relevant to the subject.

Currently business's seem to take advantage of this is sad modern day truth, "Your rights are proportional to your affordability of a lawyer!" This is the modern day Capitalism, but I digress.
