What an experience applying Indian Visa

I need to travel to India at the end of November this year to train up our new colleagues in the Chennai new office, so I have started applying the Indian Visa online through their offical website IndiaVisaOnline. After trying several times, I finally got through the final stage, however, I would like to share my extreme experience in the last couple of weeks.

1. I crashed their website at least 5-6 times on the same page, and each time took them around 5 minutes to be back and running again. Based on my test, I believe entering a website without “http://” prefix could crash it. I am really thinking about to test it again..

2. I had to squeeze in phone numbers and addresses into the same field that has 80 character limit, which forced me to truncate random characters to make them fit and at the same time it became totally unrecognisable address. So what’s the point here??

3. The passport and business card need to be uploaded in PDF format, well, fair enough, but why 300K limit? I had to keep shrinking the size in PNG format, convert and then repeat the loop, until I can barely see the text on my passport!! THIS ISN’T 1980s folks!!! GO TO OFFICEWORKS AND BUY A HARD DRIVE!!!

4. Now, after several hours of trying, I finally got to the last step. And what a surprise in the success message, with every piece of information missing on the confirmation page. I am wondering, should I call them to confirm if I made through or not?

Use my manager’s word, “A monkey with no arms could code better than whatever el-cheapo graduate they fished out of the fail pond to write this website”!!

I am sure that there are other guys out there have the same experience as mine, has anyone complained to the officials?

How to Disable the Facebook Friend Finder Suggestion

I have been REALLY annoyed by Facebook when it keeps suggesting me the strangers that I do not know on daily basis, including Facebook site and especially on my mobile phone. I am really getting pissed off and about to uninstall Facebook if I can’t find a solution to this. Lots of people saying there is no way of doing it as it is built in by Facebook and there is no settings to control it.

Today, I found this article How to Disable the Facebook Friend Finder Suggestion, and I thought to give it a try. This article suggests that those friends suggestions were made based on your imported contact list, so I followed the steps and took the following screenshots.

Step 1:

Navigate to your Facebook page and find the “PEOPLE YOU MAY KNOW” section, click on “See All” link:

Step 3:

Click “Remove all contacts,” and then click “Remove.” A status message appears, advising that a confirmation notice will be sent to you.

Step 4:

Currently I am still waiting for confirmation regarding this action, 30 minutes passed and my contacts still in my list.

Let’s see what happens tomorrow.

Hadoop Administrator – Cloudera Certified

I had some drama yesterday when I was trying to setup my laptop for Cloudera’s Hadoop Administrator Exam with Innovative Exams (http://examslocal.com/). I was unable to share my screen inside Chrome with the examiner. I spent about 20 minutes trying different ways and finally it worked, but I had no idea what the problem was and how I fixed, it just happened.

Anyway, the exam went smoothly afterwards and it took 90 minutes. I had taken the practical exams lots of times before this and I have to say that there are lots more trickier questions in the actual exam than the practical one. And some of the questions, although not many, that you can not find in the course note, meaning you will have to do lots of practical work with Hadoop by hand to know the answer.

I got the score back straightaway after the exam, and guess what, the result was PASS. I will get the actual certification confirmation in about 2 business days. Oh Yeah!


Now next one is the Developer certification. Cloudera is in the process of changing the exam structure for the Developer course, and there will be some practical questions, meaning you will have to actually write some code, rather than pure single/multiple choice questions.

Wish us luck!!

Booked in Cloudera’s Hadoop Administrator Certification Exam

I booked in the certification exam for Cloudera’s Hadoop Administrator to be done this Tuesday morning at 10AM. Cloudera recently changed the way the exam is conducted. Students used to need to go to a specific exam centre and sit inside a classroom for the test, but now it is all done online through a partner called Innovative Exams.


The way it works is to install a chrome extension from Innovative Exams, and allow them to watch you, both your face and desktop monitors remotely, via web cam and the chrome extension. They will catch you if you try to cheat. It is very convenience since you don’t have to physically go to another place for the test, but it does feel a bit odd when someone is watching all your movements for the whole one and half hours.

Anyway, I have studied hard and now ready for the exam. Wow, the very first exam since I graduated from Uni almost 10 years ago. Fingers crossed.
