I recently got my British Passport and was travelling back from India to UK from Chennai airport. Having had a bitter experience with Air India, decided to travel with Emirates who had good reputation in the Airline Industry
My flight was from Chennai to London via Dubai. As usual, landed in the airport, checked in my baggage and heard something unusual. The support staff was talking to some foreign passengers and asked whether they need Exit Row seats. I was instantly shocked as getting an exit row seat is not an easy job, it gives more leg space and one of the finest seats in the plane. To add more surprise, the foreign passengers do not know the meaning of exit row seats and was asking whether they need to pay any extra money for that.
I did not bother to ask the staff as I always preferred aisle seats as it is easy for me to step out and step in. Moreover, I was travelling alone and it did not matter where I was sitting. I was already homesick and in dull mood on going back to London after spending couple of months in India.
After all the security checks were over, I was waiting in the lounge with 2 hours of boring time to kill. The support staff were announcing some names before boarding as usual to verify some details of the passengers. I was in the toilet when I heard my name being called by the staff. It was a surprise to me as no airlines have ever called me before boarding. It was the first time and so many things were running in my mind. Did anything went wrong with my details? Am I a terrorist? Why are they calling my name? All sorts of negative things were creeping in, when I went there, they asked my boarding pass and tore it into two. I was instantly shocked to see and looking at them berserk. They gave me another boarding pass with different seat number and I was about to ask why, then the lady told me in a smiling way that I have been upgraded to ‘Business Class’.
Yes, you heard it right, it was Business class. It was like winning a lottery to me as I never get these sorts of benefits in my life. It was a perfect send off for me with all these homesick thoughts being carried over in my mind.
I instantly called my wife and brother and made them jealous. I did not bother to think about why they had upgraded my class and more importantly why me? Then when the Boarding announcement came, I got priority boarding due to business class and standing along with all other Business class passengers.
It was a bit of shyness and tension prevailing in my mind as I have never travelled in Business class. I was fully prepared for this since it was like travelling for the first time in a flight. Looking at those seats with hi-tech gadgets, I was totally confused and looking all other on how to operate these things.
I learnt something over there by looking at fellow passenger who were also upgraded to Business class. Then I realized that the Airline had upgraded most of the single passengers who had Foreign passport as sort of marketing campaign to boost their Business class.
I did not know how to react as whether to cherish the moment or think about the fact that it was not offered to any Indian passport holders. I am just writing this incident to narrate how certain possessions can change one’s life and the way people perceive it.
Human beings are rated now based on their power and status and not by their character. This is unfortunate reality of today’s world.
I own an apple iPhone 5 which I am totally in love with because of its design factor and powerful computing. My phone is my oxygen, it has evolved from need to necessity. As a regular traveler, it always run out of juice due to constant usage of songs, maps and social networking.
So i ended up carrying the iPhone charger with me always. Wherever i stop by, i look for a charge point in MRT, bus stations and airports. After considerations, bought power bank to charge on-demand but still have to carry the long iPhone charge cable. Because these power banks usually don’t come up with lighting cable and iPhone does not use a standard charging port like other android phones.
This completely does not serve my purpose of carrying a slim phone with bulky charges and cables. Looking at options, I had opportunity to try the CHARGEKEY from Nomad.
It is a portable lighting cable that looks like a key chain. Best part is it is Apple Certified. It can charge and sync as well. Look at a situation where you need to copy some pictures from your iPhone and you can always pull up your keychain to do so.
Using Nomad CHARGEKEY for iPhone, I always feel like an international spy with high tech gadgets, it makes me distinct in a crowd. The best part is the key looks so thin and light but at the same time it is very rigid and rugged in quality.
It can hold your iPhone seriously !!!!!

Looking at the title, you might be wondering why I would post an article about a basic error message shown by the Google Chrome Browser. “Google Chrome didn’t shut down properly” was a normal error that you see when the browser or system crashed during the usage. But for some, it is a daily welcome message. There is this on-going issue which some users experience with Google Chrome browser. Every time you open Chrome, you see this error message appearing on your browser, in spite of closing properly.To me, this is annoying issue – completely, I don’t want to see it at all. Although there is no official fix or answer from Google, a deep search for solution in several forums resolved my problem. I have consolidated the steps for you.
Fixing the error message:
1. Open Google Chrome, Go to Settings, click Show advanced settings, and scroll down to the bottom.
2. Under System, uncheck “Continue running background apps when Google Chrome is closed” and close the settings tab.
3. Go to About Google Chrome (Below Settings), in About Chrome Page, click the Chromium Link. The Chromium site is opened in another tab.
4. Close the browser properly. Wait for 5 Minutes. Restart the computer.
These steps look completely idiotic, but who cares? My issue is resolved.
Another Alternative Solution:
Delete the user account and disconnect the google account. If you don’t really need a Google user account linked to your browser. (I personally don’t prefer this option because I wanted all my plugins and settings to be synced across different devices).
This is my 50 cent suggestion of how two factor authentication should change in the future. With an increase in sites adopting them, you will end up having an average of more than 20 different two factor authentication codes in your mobile.
Two Factor Authentication codes via sms are just optional and purely dependent on your mobile network availability, i don’t prefer receiving sms codes for each of my sessions. The best so far is the Google Authenticator tool which is available in all cross platform mobile operating systems. So like an RSA key, the Authenticator tool can generate the codes offline and does not require data connection.
So what is going to happen in the future ?
I have 5 accounts linked with my Google Authenticator that includes my two google accounts, dreamhost, lastpass and dropbox. Evernote and Linkedin have introduced two factor authentication and they are going to be in queue for me.
There’s no doubt that i will end up having a minimum of 30 accounts very soon and the current Google Authenticator tool will let me scroll to search for my code out of this 30 accounts. By the time i locate the right account and enter the code, the time expires and code changes. So in terms of usability there is necessarily a change.
So here is my proposal (sorry if it sounds dumb)
Instead of entering the code manually for every account, each account added in Google Authenticator should have a unique callback url or Google should provide a push service which securely allows third party services to send request to our Google Authenticator client in our mobile.
Update: After having a discussion with my friend Srinivasan Annamalai, one of my Technology Evangelist, we concluded few things for better security and also in terms of usability, Google should provide a service to third party services which gives permission only to trigger an action to Generate Secure code associated with concerned account and pop up the same in user mobile screen (on-demand action).
So the next time you want to login using step two authentication, all you have to do is take your mobile, fire up the app and wait for a request made by your service provider to Google, the app will Generte code and pop it up. So you enter it. Thats it. Tada !
By this way you can manage N number of two factor accounts using a single authenticator application…

By default your MySQL Server has default configuration to allow only local connection. So if your application connects MySQL in localhost, then the basic configuration can be left untouched.
If you are planning to allow and enable remote access to MySQL server, then follow the steps below :
Find the MySQL configuration file which mostly is located at /etc/my.cnf. Using a shell editor like vim or nano, find the following line and comment it
bind-address = x.x.x.x (x.x.x.x points to the ip address you wanted to access from remotely, incase multiple servers, just comment it like below)
#bind-address = x.x.x.x
Also for people using old MySQL server, make sure you also comment the following line
# skip-networking
Restart your MySQL server
service mysqld restart
and try to connect your application with database present in remote server.
Note: You also need to give GRANT access to the db user on that particular DB.
For those who have been keeping up with the news must be aware of Noida based Pantel Technologies which sells co-branded BSNL Tablets. Recently they launched a new higher end model called Penta T-Pad WS802C. I had a chance to try it and been using it for more than a week. So this was actually my second tablet after the ipad. One thing I could notice is that tablets are drastically changing the way we consume the content. Also we have vast array of choices for buying a tablet, which varies on aspects like features, hardware and cost. In India, cost is a potential factor for every product and that’s where T-pad WS802c impressed me.
Overview:
T-Pad WS802C is a budget tablet which comes around 14700 INR. With my hands-on experience, I am writing a personal review on it. To make things more clear and concise, I am going to split into topics. Ok here we go 🙂 You can also checkout the video above to feel the looks.
Specifications:
Powered by Cortex A8 1GHz, 512mb DDR2 Ram, 4GB internal memory and runs on Android 4.0.3 (Ice Cream Sandwich). It has dual camera (2mp rear + 0.3 front), GPS, 3G Sim Slot and other default stuffs. More detailed specs here.
Tablet Body:
Comes in white colour with 8” display, which is bigger than other budget variant. The back panel is a patterned white design with protective lamination that prevents scratches and gives good resistance. The Touch screen is very responsive like Samsung tab and Blackberry playbook. Overall body is made up of hard plastic and perfectly strong for a tablet.
Performance and Usage:
I performed several benchmark tests and certainly the tablet is up to the level on budget category. Boot speed is pretty quick but certainly at some point multi-tasking lags a little especially when 7+ applications are open same time. Sometimes it crashes and reboots completely. Tried playing couple of high end games and it is seamlessly fast but the negative factor is that it heats up very quickly. The Temperature is too high at some point where you cannot even hold it in your hand. Comparing other tablets in this segment this one emits more temperature. Seriously they need to consider redesigning their heat exhaust or sink.
Battery:
The total standby time is more than 6 hours but the battery drains very quickly within 4 hours on performing normal tasks. We also have to remember the fact that you can actually make calls; receive text messages in this tablet with a 2g/3g sim card. So turning of cellular network can increase your battery life.
Support:
The first question that sparks anyone when buying a brand which is unknown is the support and warranty. Unlike any Chinese products or Unfamiliar New Indian Brands, Pantel Technologies can be added to exception list because they have service centres all over India.
Comparison:
Here is my comparison with tablets in the same budget range.
| Features | T-Pad WS802C | Huawei MediaPad | HCL ME Tablet AM7-A1 |
| Operating System | 4.0.3 Ice Cream | 3.2 Honey Comb | 2.2 Froyo |
| CPU | Cortex A8 1GHz | Dual-core 1.2Ghz Qualcomm | Cortex A8, 800MHz |
| Screen Size | 8 Inches | 7 Inches | 7 Inches |
| Memory | 4GB Internal + Ext | 1GB Internal + Ext | 8 GB + Ext |
| Camera | 2 mp + 0.3 mp | 5 MP + 1.3 MP | 1.3 MP |
| Standby Time | 6 hours | 6 Hours | – |
| Cost | 14699 INR | 19990 INR | 18000 INR |

People who use shell to install packages or application in their Linux servers usually need to keep this command handy. Every time they download and unzip a folder, they are in a position to move all those files to a parent directory they already created.
For example you download wordpress application and extract it, but those files are extracted in another folder that comes up with the zip package. What you need to do at this point is to move all those files from that particular folder to your parent directory which you usually created and planned to host. In most cases it will be your Application root folder.
Consider a scenario where you are in folderX, you download a package file and extract it but instead of extracting it directly in folderX, it creates another native folder that comes up with package like folderY. So all those extracted files are in path /folderX/folderY/ 🙁 thats bad !!!
Run this simple move file command outside the folderY, you need to be in folderX when you run !
mv folderY/* .
The above command will move all the files and folders inside folderY to folderX 🙂 That works like a charm! Yeah try it. Always ensure to be careful while running commands like mv, rm. If you don’t give the correct part, things will mess up and you end up doing the operation at wrong place.
So you deployed one of best bug tracker system in your ec2 instance and was wondering how to configure its email setting with SES ? After Amazon Introduced SMTP accounts, things that were so complicated become so easier. Every application that supports SMTP connection method made it possible and compatible to be used with Amazon SES.
But things are not simple with Mantis Bug Tracker Configuration because the basic configuration file does not contain the necessary attributes needed for configuring Amazon SES SMTP email or Google SMTP Accounts. They are just enough for an ordinary SMTP settings. So after doing some research over a couple of forums and user tryouts, the following configuration listed below works
# — Email Configuration —
$g_phpMailer_method = PHPMAILER_METHOD_SMTP; #For SMTP Method
$g_smtp_host = ’email-smtp.us-east-1.amazonaws.com’; #Your SES SMTP Host
$g_smtp_connection_mode = ‘tls’; #It is mandatory for SES and Gmail SMTP
$g_smtp_port = 587; #For some Reason only this port was working in SES
$g_smtp_username = ‘SMTP Username’; # Your SES SMTP Username
$g_smtp_password = ‘SMTP Password’; # Your SES SMTP Password
$g_administrator_email = ’email@sample.com’; #Email displayed at footer (Must be an approved sender list in SES)
$g_webmaster_email = ’email@sample.com’; #Verified SES Sender Email
$g_from_email = ’email@sample.com’; # From Address (Verified SES Sender Email)
$g_return_path_email = ’email@sample.com’; # the return address for bounced mail
$g_from_name = ‘From Name’;
$g_enable_email_notification = ON;
The above configuration will do the trick and you can start receiving emails from Mantis Bug Tracker 🙂 Fire up the comments section if you had any doubts in it !!!
