Activate Facebook Timeline

Walker — Sun, 29 Jan 2012 16:29:08 +0000

Facebook Timeline has been around quite some time, but activation isn’t automatically pushed to all user profiles.

If you have no idea what is that, go watch the video and sample page on Introducing Timeline, and if you buy the idea, there is a green button called “Get Timeline” (bottom-right). So, just click it to activate Facebook Timeline on your profile.

After activation, you’ll see a new presentation for your FB profile. To me, the cover photo feature is simply eye-catching! Besides, it’s darn easy to tell (the world) what I’ve done in this month of last year via timeline next to cover photo, sharing apps activities like what music am listening to (a similar feature exists in Windows Live Messenger/MSN).

How To Check DB2 Table Size?

Walker — Sun, 15 Jan 2012 17:32:07 +0000

For IBM DB2 v9.x users who would like to find out the total physical disk space used by a table, you can get the estimated table size from SysIbmAdm.AdminTabInfo administrative view.

Besides, DBA can also retrieve logical size of table from AdminTabInfo. For detail information, please refer to IBM DB2 9.7 LUW official guide.

This guide is tested on both DB2 9.7 and DB2 9.1 installed on Redhat Enterprise Linux 5.7.

For example, the following SQL SELECT statement is used to display physical size of each table in a database, sorted in ascending order (run it at Linux/Windows command prompt as DB2 CLI command):

db2 "SELECT SUBSTR(TabSchema,1,15), SUBSTR(TabName,1,15), TabType, (Data_Object_P_Size + Index_Object_P_Size + Long_Object_P_Size + Lob_Object_P_Size + Xml_Object_P_Size) as Total_P_Size FROM SysIbmAdm.AdminTabInfo ORDER BY Total_P_Size"

If you only interested in checking table size of particular table or schema, just use WHERE clause to get specific result.

Kaspersky Causes Cisco AnyConnect VPN Client Unable To Establish Connection

Walker — Mon, 01 Aug 2011 16:39:18 +0000

The Cisco AnyConnect VPN Client v2.4 keeps on saying it’s unable to establish a connection and record some errors such as “NETINTERFACE_ERROR_INTERFACE_NOT_AVAILABLE” in the Windows Event Log.

On Windows Device Manager, there is a new network adapter called “Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64″ appears in disabled mode (this might be the answer of error in Event Log). Though I’ve manually enabled the virtual network card, it’s still disabled by Cisco VPN client during its attempt to establish connection :(

I suspect this has something to do with Kaspersky Internet Security software, but hey all Cisco-related programs are set to be automatically grouped as “trusted” apps granted with all rights.

I can’t figure out what else to be configured, until I found this trick from Google.

How to fix Cisco VPN client connection error caused by Kaspersky IS 2011?

1. Classify all Cisco program as trusted apps granted with full right (as those granted to Windows system programs).

2. Set Kaspersky IS to “monitor selected ports only” and don’t monitor HTTPS (port 443):

Note, there is an alternate trick proposed by others, which configure Kaspersky to not scanning opened files and network traffic of Cisco VPN program. Personally, I don’t prefer this alternative, but it’s up to you which one to use.

How To Download Adobe Reader Full Installer From Official Site?

Walker — Tue, 26 Jul 2011 17:57:28 +0000

Since Linux users are allowed to get the latest PDF reader setup file in full, why can’t Windows users allowed to download Adobe Reader offline installer to facilitate multiple installations?

If you’re using Windows and desperately looking for the latest Adobe Reader X full installer, here is a trick to get it directly from official site:

Yes, by tweaking user agent string of web browser (or download manager)! For example:

Right click on Google Chrome shortcut and select Properties, go to Shortcut tab, then append --user-agent="Mozilla Linux" to the string in Target box:

Note, that UA am using is dummy. One of the proper UA of Linux Firefox is this:

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b5) Gecko/2008042803 Red Hat/3.0b5-0.beta5.6.el5 Firefox/3.0b5

Just in case the dummy UA doesn’t work, change it with a proper UA and try again. Am using this to get Adobe Reader X 10.1.0 standalone installer for my 3 Windows machines (without having to download thrice!).
