The perfect time

For me, the perfect time to do something is when I have no time at all to do it.
Is this for everyone or just for me?
Just take blogging for example, it seems to be the perfect thing to do only during exams or the night before assignment's due date. And when that's over, the moment seems to be gone and blogging doesn't feel that fun any more :(.

who should we love

we all hate Pakistanis because of what they did to us during 1971.
then we should hate US too because without US support and help the war atrocities might not be so bad. (another link)
then we should hate India too because how they have been treating us since 1971.
And last but obviously not the least, we should hate ourselves for what the BDRs did to the army families because all the bdrs were bangladeshi.

Now, if we keep hating everyone in the world, who should we love?

তোমার আমার মাঝখানেতে

একটি বহে নদী ,

দুই তটেরে একই গান সে

শোনায় নিরবধি ।

Khonek dekha by Rabindranath Tagor


যেমন ঢাকা ছিলে তুমি

তেমনি রইলে ঢাকা ,

তোমার কাছে যেমন ছিনু

তেমনি রইনু ফাঁকা !

তবে কিসের তরে

থামলে লীলাভরে

যেতে যেতে পাড়ার পথে

কলস লয়ে কাঁখে ?

একটুখানি ফিরে কেন

দেখলে ঘোমটা - ফাঁকে ?

libpng.so.2 error

***: error while loading shared libraries: libpng.so.2:
cannot open shared object file: No such file or directory

To avoid this error:

1. Install libpn3:

sudo apt-get install libpng3


2. And rename it to libpng2:

sudo ln -s /usr/lib/libpng.so.3 /usr/lib/libpng.so.2


Thanks to Jacques for the solution.

player/stage/gazebo help

http://yorkroboticist.blogspot.com/2009_11_01_archive.html


and a tutorial Player/stage tutorial

SLAM tutorial : SLAM
Excellent slam example: slam for dummies

didn't find any example for player/stage 3.*, so i installed player 2.0.5, and stage 2.0.3

got the following error

unable to open color database /usr/X11R6/lib/X11/rgb.txt :
No such file or directory (stage.c stg_lookup_color)

To correct this problem, player/stage needs a link to the X11 color map in the place it expects:

sudo ln -s /usr/X11/share/X11/rgb.txt /usr/X11R6/lib/X11/rgb.txt


detailed solution: here

Java client for player/stage: here

DNS security flaws




full story


In practice the DNS service behaves very much like the /etc/hosts file on your computer, which is where the system initially looks up name resolutions before relying on the DNS system. The file is basically a list of IP addresses followed by the name you've associated with those IP addresses. For example, if you edit the file you can associate any domain name with any IP address of your choosing.

1. Open Terminal and enter the following command to edit the hosts file

sudo pico /etc/hosts

2. Go to the bottom of the file and enter the following:

74.125.19.106 www.apple.com

3. Press control-o followed by the return key to save the file
