MongoDB index completion status

-
MongoDB allows you to create indexes and run them in the background using the ensureIndex. Often indexing is a time consuming process and may take long if indexed upon string and the collection contains millions of records. For example, Indexing on my collection having 50 million records took almost 15 minutes. Here is the script that can be used to monitor index operation status.


var ops = db.currentOp();

 if(ops.inprog && ops.inprog.length > 0) {
    for(o in ops.inprog) {
        var op = ops.inprog[o];
        if(op.msg && op.msg.match(/bg index build/)) {
            print(op.opid+' - '+op.msg);
        }
    }
}

 copy above code into test_index_status.sh, execute mongo index_status.sh and see the magic!!!

Proper way to have an anchor tag with onclick event

-
Anchor tags are one of the most common HTML tags used in pages. If the user right clicks on the anchor tag he/she will be provided with an option of 'Open in new Window/Open in new Tab'. This will happen only if the anchor has href attribute. Sometimes it is required to do some other action (like making ajax request) on click of the anchor link and also provide the right click option for the same anchor. Natural practice by web developers. <a href="javascript:void(0);" onclick="alert('i am here');">Click Me! </a> Click Me without link for anchor! Correct way to add anchor tags without losing anchor properties. <a href="http://www.blogger.com/amareswar.blogspot.com" onclick="alert('i am here'); return false;">Click Me! </a> Click Me! In the above link, you can observe that the user can right click on go to the respective link and onclick will do the custom action provided by the developer.

CORS issues with IE9 and workarounds

-
CORS(Cross-Origin-Resource-Sharing) is one of the features in HTML5 feature stack that enables a page to make AJAX requests to other domains. This feature is introduced to circumvent the Same-Origin-Policy . I am not discussing about CORS in detail here as there are lots of online resources available. I am working on a product where html files are served from one domain and back-end requests should be made to another domain (of course sub-domain) for security reasons and API clarity. Luckily we need to support browsers with HTML5 capabilities like Chrome > 14, Safari  > 5.0.5 , Firefox > 9, IE >8. I thought that IE9 is HTML5 complaint and promised to have support for it. I could have investigated a little bit  Application was implemented and we are running for release. Suddenly while going through entire flow we realized that IE9 is not making any CORS requests. From then on our hunt started. Searching blogs, articles, stackoverflow for solutions. I am her...

I have two boys one is 10 years and another one is 3 years old. "Idle money is like a radio-active material, its value depreciates over-time" I came to know above FIRE (Financial Independence and Retire Early) in 2013 while searching for investment opportunities. Let's jump into the topic. My goal was to be financially independent by 40. I just want to have the financial independent and perceive my interests instead of wasting my precious time churning out money for my family. The investments are broadly classified as the following categories Indian Real-estate - Stable and reliable and it never disappoints as long as the decision is good Indian stock market - Unreliable  US real estate - Very slow growth (non bay-area) with lots of wait times and a bit unreliable US stock ...
