Free Personal Source and Version Control Solution: Use SVN over Dropbox.

   Want to use some source control and version control tool for your personal use? And don’t want to use public repositories github? And also want to save your all source over a safe, reliable and sharable cloud? Then simplest and free solution is to use SVN, a very good version control tool, and save your SVN repository over your Dropbox account which will save your source over a safer cloud.

   For doing this download and install SVN tortoise client and Dropbox application on your machine. I hope you have an account on Dropbox : a file hosting service operated by Dropbox, Inc. that offers cloud storage, file synchronization, and client software(description copied from Wikipedia). Dropbox takes care of storage, safety, backup and sync for you.

   Once you have installed Dropbox and configured your account, you will be able to see your Dropbox folder on C:\Users\[YourUsername]\Dropbox. By default it syncs all of your Dropbox folders but you can select the folders to be synced from 

Dropbox > Preferences > Advanced > Selective sync.

   Now you are ready to create SVN repository over Dropbox. You just need to follow following simple steps:

1. Go to Dropbox folder, Create a new Folder, it’s your repository so name it accordingly. Right click on this new folder and select
 

Tortoise SVN > Create Repository here
 

Then you will see a dialog saying Repository Created as shown here..

2. Click on ‘Create folder structure’ to create trunk/branches/tags structure inside this new repository.

3. Bang!! Your repository with folder structure is ready now. Click ‘Start Repobrowser’  for opening repo-browser. Remember don’t ever ever ever modify this folder(your repository folder) of your own.  As this folder is SVN repository, it’s structure and data inside it is meant for SVN only.

4. Now you need to add your source code to your own SVN repository.  For that do this :

Right click on your workspace folder > TortoiseSVN >  import > give URL of a folder under trunk (you can copy URL of trunk from repo-browser and add required folder name to it after ‘/’ ) into ‘URL of repository’ > Ok. 

5. You have added your workspace to repository but it’s not versioned yet on your machine. For that right click on workspace folder and SVN Checkout the new imported folder from repository.

6. Once you have mapped your workspace to your local SVN repository, you can use your workspace and commit files as you were committing to standard SVN repository. Those files will just be committed to local repository.

  But don’t be curious about where these files go inside repository folder on your local machine, leave it to the SVN. Also don’t do any modifications to this repository folder. SVN takes care of everything.

7. Now your source code is inside your Dropbox folder that you should mark for sync from your machine if you are using selective sync. If you do manual sync of your Dropbox then keep good practice to sync this repository folder to Dropbox whenever you do any commit or changes that you must do from repo-browser only. Also keep in mind that this folder on Dropbox should also never be modified manually.

     You also can share this Dropbox folder to your teammates through Dropbox share and your teammates can use this folder directly as SVN repository. 

How to listen music on mono bluetooth headset on android phone.

    Mono bluetooth headsets have single stream connections, so you can't stream music on them.  But Nokia phones have option to play music via bluetooth which can play music directly on even mono bluetooth headsets.
A2DP bluetooth headsets are dual stream so music can be directly played on them.

     But if you have mono bluetooth headset and android phone you can't listen music on it but only can make and receive calls. You are stuck :( 
But don't worry, there are few apps on android market which enable you to listen music on mono bluetooth  headset.

BTMono Off

     BTmono is very simple and light weight application available on android market, which can stream your media over mono bluetooth headset.


     For using this app switch on your phones bluetooth, connect your bluetooth with paired bluetooth headset, open BTmono app and click on ON button then android robot on the screen will put it's one hand up and you are ready to go. Then just play music and it will be streamed to your mono bluetooth headset.

BTMono On

There are two versions of this app available on the market, free version and paid one. The only difference that matters is what happens when you get a call while listening to music. On free version when you drop a call received while listening to music, music resumes on speaker instead of bluetooth headset and that is little embarrassing eeew. While on paid version music resumes on headset when a call is dropped. so it's your call to choose free or paid version of BTmono.
The music quality on bluetooth headset using this app is not up to mark and that's because it's mono headset.  But remember this app is really helpful to utilise your otherwise useless mono bluetooth headset.

jQuery - Difference between :eq() and :nth-child() selectors.

    In jQuery many times :nth-child(n)  pseudo-class selector is easily confused with :eq(n), even though the two can result in dramatically different matched elements.

   With :nth-child(n), first all children are counted, regardless of what they are, and the specified element is selected only if it matches the selector attached to the pseudo-class. With :eq(n) only the selector attached to the pseudo-class is counted, not limited to children of any other element, and the nth one is selected.

    In other worlds, with :nth-child(n), first all elements those are children are considered and among the children, nth child is considered then it’s checked if it matches the selector which is attached with :nth-child(n). On the other hand with :eq(n) first the attached selector is resolved to set of elements and among those elements nth element is selected independent of considering children or not.

    Also there is another important difference, that is :nth-child() is 1 indexed means indexing count starts with 1 so nth means actual nth one. While :eq() is 0 indexed with indexing starting with 0 so nth element is actually (n+1)th. This is so because jQuery's implementation of :nth-child(n) is strictly derived from the CSS specification and for all other selector expressions including :eq() however, jQuery follows JavaScript's "0-indexed" counting. 

   Let's see following simple example: 

<table>

          <tr><td>Table1-row1</td></tr>

          <tr><td>Table1-row2</td></tr>

          <tr><td>Table1-row3</td></tr>

</table>

<table>

          <tr><td>Table2-row1</td></tr>

          <tr><td>Table2-row2</td></tr>

          <tr><td>Table2-row3</td></tr>

          <tr><td>Table2-row4</td></tr>

</table>

In above tables $(“tr:nth-child(3)”) will select two elements :

         <tr><td>Table1-row3</td></tr>

And

        <tr><td>Table2-row3</td></tr>

While $(“tr:eq(3)”) will select only single element :

        <tr><td>Table2-row1</td></tr>

   
 Please try following fiddle also, run it and click a button to see what it selects. It also shows how :even and nth-child(even) are different.
