Ruby on Rails

I found this short and succint but complete presentation of what Ruby on Rails is. For beginners this is very useful to give them a head start.

Hellodeo - Voice message with expression

Hellodeo is an online video recorder with voice.

It is very simple to use. You just need a webcam and go to their homepage. It will detect your webcam and get permission to use your system resources (mic and USB port i.e. webcam) and then you record your video. Start recording and see it there itself after it is recorded and if liked it then submit it. It will be shown on their latest and greatest video and you will get a code snippet for your video. Here is my testing video.



I see multifold uses of this service -

• Voice message along with video for anybody. You can then send this video via email, through home page, put it on your blog etc. While you are on vacation you can leave out on vacation video, welcome video on blog or homepage, demonstration of some product etc.


• I would love to see this getting intergration in mobile devices. So it will be expression + voice message


• Instant streaming of live event. I am not sure what is the maximum length of video that a user can record. But can be used to generate revenue

I liked this product and would try to use it and enhance this service or create something out of it. By the way did i tell you, i was thinking about it a month back but again I am late on designing and implementation.

Fix for z-index bug for IE 6.* (Select box is always on top)

Select boxes in IE are always on top of any other div or pop up windows or other elements. Even after setting z-index for select box as -1 and z-index for div tags which holds pop up window as 100 it does not work for IE.

The fix works really well in IE and firefox (it was showing properly before also).

Fix for VBScript Error: Invalid procedure call or argument: 'Mid'

After long long time i have touched VBScript and was trying to traverse string character by character. I came across some weird error or may be i have not read VBScript for long long time.

When you try to traverse string character by character, never start with index 0 otherwise you will get the above error

Invalid procedure call or argument: 'Mid'

Along with this you will get argument 2 is invalid or something like that.

To traverse string character by character in VBScript use the following snippet of code:

/**

inputString = "String traversal in VBScript";
stringLength = len(inputString)

For i = 1 To stringLength
mychar = Mid(inputString, i, 1 )
WScript.Echo "My character is "+mychar
Next

*/

This is one of the way to traverse string in VBScript.
