i used to think myself as a loyal airtel customer. i am using present connection since december, 2005. prior to that, i was using an airtel <a class="g-profile" href="https://plus.google.com/107535994725801213380" target="_blank">+MTV</a> connection for few years.<br />
in 2014, i joined <a class="g-profile" href="https://plus.google.com/117104750085491410303" target="_blank">+Sikkim Manipal Institute of Medical Sciences</a> as an assistant professor. i tried to continue using my airtel sim in gangtok. however, quality of connection was not only poor but most of the times, it was non-existent. i was very unhappy. however, being a loyal customer, could not leave the connection behind in spite of higher call charges and poor coverage.<br />
after several failed attempt to the <a class="g-profile" href="https://plus.google.com/117835197494824956072" target="_blank">+Airtel India</a> customer care through social media (twitter, facebook), i decided to resign from SMIMS and returned to west bengal in 2015. finally, <a class="g-profile" href="https://plus.google.com/112353470957473641776" target="_blank">+airtel India</a> has decided to share some love. it is now offering 3G speed to 2G net connections. i received this offer few days back. under this offer, i was asked to enable 3G connection in my mobile network and enjoy 3G speed for 2G net connections.<br />

some of my twitter interactions with airtel cc are as follows:-<br />

<div class="tr_bq">
it's a long time since i have posted anything in this blog. my last post was more than a year back, 12th July, 2014. since then for various reasons, i was not able to give any time to this blog. finally had some free time available in this Puja.</div>
during the Puja, decided to install Debian 8 stable in <a href="http://www.flipkart.com/asus-1015e-cy041d-netbook-cdc-2gb-320gb-dos/p/itmdm86q3mxmfpx5?pid=COMDM86KN5MFRBVJ" target="_blank">my small </a><a class="g-profile" href="https://plus.google.com/115201921530304855679" target="_blank">+ASUS</a> notebook. i bought this one from <a class="g-profile" href="https://plus.google.com/109591199284807005836" target="_blank">+Flipkart</a> one year back but i was not using this very much. recently though, i have started using this one a lot. i was using ubuntu 12.04; planned to change it to something recent. for various reasons, i was always interested in <a class="g-profile" href="https://plus.google.com/111711190057359692089" target="_blank">+Debian</a> ; however, never had the courage to try this distro. during this Puja,decided to give it a try. keeping in mind about the low level hardware support, i planned to install debian with <a class="g-profile" href="https://plus.google.com/104079951048020884859" target="_blank">+LXDE</a>.<br />
<br />
downloaded the torrent file from <a href="http://cdimage.debian.org/debian-cd/8.2.0/i386/bt-cd/" target="_blank">debian.org</a>. before this, i have always used unetbootin for writing the ISO image in a USB. Debian, though, actively discouraged this in the <a href="https://www.debian.org/CD/faq/#write-usb" target="_blank">FAQ section</a>. followed the guideline and used the cp method (cp <file> <device>) to copy the ISO file to USB. however, the first time i tried that, faced some problems. the USB drive was not bootable. tried again and was successful in the second attempt.<br />
<br />
inserted the USB and booted the laptop while repeatedly pressing the escape button. this lead me to a screen asking me to decide where to boot from. selected the USB and booted form it. here also, i faced something unique. until now, whichever distro i have tried, they usually offer an option of running a live environment. however, debian did not offer me any such option. while going through the FAQ section again, i found that live distro is offered separately. anyway, selected the graphical install option form the options provided.<br />
overall the installation process is quite simple. the guidance was given in a well described fashion. the only thing i decided to do manually was selecting the drive in which i want to install it. everything else was managed automatically by pressing the "continue" button. one other thing, i choose to install both LXDE and XFCE. <br />
after the installation was finished, i booted the machine. i found few things-<br />
<ol style="text-align: left;">
<li>no firefox; only iceweasel (however it was known to me)</li>
<li>mousepad not working</li>
<li>keyboard layout for bengali unavailable.</li>
<li>if we install only LXDE, network manager is unavailable. it comes with wicd. faced some problems with wicd. so installed network manager and removed wicd. </li>
<li>changing notification from top right to bottom right. i am using the lower panel; so notification at the top-right corner looks odd. </li>
</ol>
regarding browser, i installed "<a class="g-profile" href="https://plus.google.com/106303841988408974064" target="_blank">+Opera</a> next" in spite of the fact that it is lacking a few interesting feature. planning to install vivaldi as well; but that's for future.<br />
<br />
upgraded iceweasel to version 41 (compared to version 38 in Debian 8). transferred my backups to the .mozilla folder using rsync and iceweasel was ready to do its job. <a href="http://mozilla.debian.net/" target="_blank"> </a><a class="g-profile" href="https://plus.google.com/107964393728911462914" target="_blank">+Mozilla Firefox</a> backport ppa really helped to update the browser.<br />
<br />
the main difficulty was to make the mousepad working. it was not responding to the clicks. <a class="g-profile" href="https://plus.google.com/116899029375914044550" target="_blank">+Google</a> came to help me. after a detailed search, entered the following command in the the root terminal:<br />
<br /><blockquote>
mousepad edit /etc/X11/xorg.conf.d/synaptics.conf</blockquote>
then edited the text file. text file looked like this after editing<br />
<blockquote>
Section "InputClass"<br />Identifier "Touchpad"<br />MatchIsTouchpad "yes" <br />Driver "synaptics" <br />Option "MinSpeed" "0.5"<br />Option "MaxSpeed" "1."<br />Option "AccelFactor" "0.075"<br />Option "TapButton1" "1"<br />Option "TapButton2" "3" <br />Option "TapButton3" "2" <br />Option "VertTwoFingerScroll" "1" <br />Option "HorizTwoFingerScroll" "1" <br />Option "VertEdgeScroll" "1"<br />Option "CoastingSpeed" "8"<br />Option "CornerCoasting" "1"<br />Option "CircularScrolling" "1"<br />Option "CircScrollTrigger" "7"<br />Option "EdgeMotionUseAlways" "1"<br />Option "LBCornerButton" "8" <br />Option "RBCornerButton" "9" <br />Option "TapAndDragGesture" "1" <br />EndSection</blockquote>
the next job was to update the keyboard configuration file. this is necessary to be able to write Bengali. so, used the following command and changed the keyboard configuration file as follows:-<br />
<blockquote>
mousepad /etc/default/keyboard</blockquote>
<span style="color: black;"> KEYBOARD CONFIGURATION FILE</span><br />
<br />
<blockquote>
# Consult the keyboard(5) manual page.<br /> XKBMODEL="pc105"<br />XKBLAYOUT="us,in"<br />XKBVARIANT=",ben_probhat"<br />XKBOPTIONS="grp:alt_shift_toggle"</blockquote>
<br />
<blockquote>
BACKSPACE="guess"<br /><br /><br />next, changed the notification location from top right corner to bottom right corner using the following command <br /></blockquote>
<blockquote class="tr_bq">
<span style="color: black;">xfce4-notifdy- config</span></blockquote>
<span style="color: black;"> </span><br />
<span style="color: #eeeeee;">and choosing the proper option from the GUI. </span><br />
<br />
<div style="text-align: center;">
<span style="color: black;"> </span><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgEwV-oiYjys8Ng1jAKj_f0EbfgtWye8ehuhmyCFL6bFTmKA_EZYI-TA2SVfcKiMY0ietjRMDK-BIIeJJzME5YqrKvSdHFd42uwW8ImdFflKznnUhhs4L_3p0mdOzZmFg_ZbuA_6ad-Yw/s1600/Screenshot+-+Friday+23+October+2015+-+10%253A50%253A10++IST.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="223" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgEwV-oiYjys8Ng1jAKj_f0EbfgtWye8ehuhmyCFL6bFTmKA_EZYI-TA2SVfcKiMY0ietjRMDK-BIIeJJzME5YqrKvSdHFd42uwW8ImdFflKznnUhhs4L_3p0mdOzZmFg_ZbuA_6ad-Yw/s400/Screenshot+-+Friday+23+October+2015+-+10%253A50%253A10++IST.png" width="400" /></a></div>
<br />
<br />

orkut is a social networking site, launched in 2004. i still remember it was the first social networking site i have participated. it is going to be discarded by google, just like google reader, google buzz etc. when google reader was thrown away by <a class="g-profile" href="https://plus.google.com/116899029375914044550" target="_blank">+Google</a> , felt very sad and cursed google for continuing orkut but discarding google reader. apparently, the curse affected orkut; not feeling very good really.<br />
