MyLittleAdmin -- Administering SQLServers on the Web

MyLittleAdmin -- Administering SQLServers on the Web

Administering a SQLServer typically after the website has been transferred to the production site is always night marish and particularly connecting through a desktop enterprise manager, and typically when you do not have the luxury of fast broadband.

I came across this little tool called MyLittleAdmin, whose lite edition seems to address this issue, satisfying the needs and requirements of many people.

Check it out at MyLittleAdmin homepage.

Web.Config Editors

Web.Config Editors

The most elegant feature of .NET application compared to classic ASP is that most of the things are now configurable in simple and standard XML Configuration files. The most significant among them is web.config files for a particular application and machine.config for a typical .NET Framework installation for the entire system.

Don't worry. I am not going to bore you into the internals of Web.config. For more information on the same, check out this MSDN link.

Here we would see, some of the free editors and or third party solutions that make editing and managing a web.config simple for system administrators and other personnel who maintain the website but not too tech-savvy to know the internals of the same.

Third Party Solutions
  1. Hunterstone Web.Config Editor. I had seen that HunterStone WCE was giving promotional offers for free download sometime back but I think that offer is not available now. But it is a very simple tool to manage the web.config files.

Windows Media Player Rudimentary PlayList

Windows Media Player Rudimentary PlayList

Normally, when I used to listen to Ayyappa Bhajan songs, basically MMS URLs I had to copy one by one into Windows Media Player to listen. I was thinking whether I can create a simple playlist that Windows Media Player can automatically recognize the sequence and play one after another.

There are Windows Media Player playlist XML files that you can create for them. But I found one more simple solution from a web discussion forum over here.

It is directly simple. Create a simple text file default.m3u and enlist the supported file type URLs and Windows Media Player would play for you.

A sample would be like this, as mentioned in the discussion forum (default.m3u)
