New HTML 5 tags and IE 8.0 Beta

I tried some of the HTML 5 only tags and did not see any difference. It could not play audio and Video. The browser was not using the IE 7.0 Emulate switch.

One thing did happen: My Blog editor went crazy. Lost the place holder for Title and the formatting buttons on the editor lost control. This was posted using FireFox 2.0.

Can the new tags be used in CSS rules?

Panorama: SQL Anywhere 11's BETA is out

I down loaded 'Panorama' and installed it on the same machine side by side with others SQL Server 2005, Oracle 10G Xe, IBM DB2 and also SQL Anywhere 10.

Initial findings extremely encouraging...

* The installation was uneventful, easy and smooth. A very positive feature

* The document installation was easy

* Visual improvements many, especially the dialogue boxes for connections [ the only one I evaluated in detail]

* The installation updated the .NET related items that you would see on VS 2005, namely, the Sybase Central and ISQLAnywhere.
* Ás per my original wishes, SQL Anywhere queries can now return data in 'JSON'

* Here is a quick view of the 'Demo' database's overview in Sybase Central 11.

Strange behaviour of Data Link File

Problem started here...
I removed an instance of SQL Server 2005 (evaluation edition) but some how parts of it remained. I tried to clean up to remove the existing SSRS and in the process the ability to create a UDL file presented a problem.

The Problem
In the Data Link properties page when I try to refresh the server I get the 'Microsoft Data Link error "Error enumerating data servers. Enumerator reports Únspecified Error". Normally it would reveal all available servers.

My troubelshooting begins...

I associated this with the MS Ole DB errors (bad guess) and tried to repair the MDAC 2.8 which in itself was another tedious web search followed by a final repair. Apparently this is not straight forward with Windows XP SP2. You need the original CD's and also know where the files are(see tags). This was a good resource I found on the web.

And now..
However this did not solve the original problem. Probably there was no error with the MS OLEDB but something else that the Wizard is doing. This is the problem with the Graphic User Interfaces.

Now instead of hitting the Refresh button on Data Link Properties window, I directly enter the local server with a [.] & enter the credentials. Now the connectivity test succeeds.

I still do not understand what caused the problem.

My problems with the Reporting Services in Visual Studio 2008

I have used Reporting Services with VS 2003 and VS 2005 and I am beginning to work with VS 2008. I have come across a strange problem. I used the Reporting Services Configuration utility that comes with the default installation of SQL Server 2008 November CTP. The Configuration gets completed without a hitch and I can see the Report Server databases in my Server but when I try to access the Web URL or even the Object Browser in the Management Studio I get an exception. I am trying to find out the reasons for this.

What I have found so far is that while the Reporting Services Configuration provides me with a default web URL [that I can happily click on] it does not write it to the configuration file, the RSReportServer.config. Could this be the reason?

Strangers in a strange land

During early 1960's walking around Kempegowda Circle in Bangalore I used to see these strange people selling odd things whose total value did not exceed a few rupees at that time. They definitely looked strange and they looked even stranger because their fair skins were scorched dark by the southern sun. These were the refugees from Tibet and they had come as far as they could. It was heartbreaking to think of them as refugees, and they had come from the very abode of the gods.

My sympathies are with the Tibetans who have been displaced. Indian Government gave them refuge and made 'Dharmashala' lives upto its name, dispensing Dharma. But economic ties and pragmatism has driven India to the cautious side which does not help these people. The World is sitting on the side walk and seems not to have lifted a finger.

It's time for China to give autonomy to Tibet if not an outright independence.

Want to take a XAML quiz?

What is the difference between a Windows Markup File and a XAML file? While the IE brings up a nice little button in one the other brings up a message to save the file. Opened with Notepad there is no difference between the two. Both have the same extension.

What do you understand by XAML_auto_file?

Don't Google it, you won't find an answer.

End of days for Cathode Ray TV Tubes

On hearing that Sony is going to stop making TV CRTs...

This endangered species is facing imminent extinction, but you will not regret it. This is yet another dinosaur fading away.

I personally feel great loss as I used to harvest the High Voltage sources from thrown away TV sets to power my lasers during Sydney days. Protection Status
