The challenge was that on Monday it was Holi ( the festival of colors ), so naturally no designing and printing available on Monday. Thankfully my friend was there for all the professional help, all the way from designing till printing. Here in the pic is Saleem Ahamed standing besides the posters, who helped with all the designing and priting of BootConf 2014 posters. /2011/12/10/symlink-loop-is-still-an-unsolved-problem/ Sat, 10 Dec 2011 00:00:00 +0000 /2011/12/10/symlink-loop-is-still-an-unsolved-problem/ How do I dereference a symbolic link? $ ls -l /usr/bin/java lrwxrwxrwx. 1 root root 22 Jul 20 2010 /usr/bin/java -> /etc/alternatives/java $ ls -l /etc/alternatives/java lrwxrwxrwx. 1 root root 30 Aug 9 2010 /etc/alternatives/java -> /usr/java/jdk1.6.0_20/bin/java $ ls -l /usr/java/jdk1.6.0_20/bin/java -rwxr-xr-x. 1 root root 50810 Apr 13 2010 /usr/java/jdk1.6.0_20/bin/java Lets create a chain of symbolic links: mkdir /tmp/symlink cd /tmp/symlink echo "this is a test file" > abc.txt ln -s abc. /2009/12/14/how-does-live-linux-disk-work-without-any-swap-for-applications-bigger-than-available-ram/ Mon, 14 Dec 2009 00:00:00 +0000 /2009/12/14/how-does-live-linux-disk-work-without-any-swap-for-applications-bigger-than-available-ram/ How does live linux disk work without any swap for applications bigger than available RAM? This question has occurred to me a lot of times. In the normal scenario I configure enough swap space on the harddis for my GNU/Linux installation. It looks clear that whenever a new request for memory is made by an application, the Linux kernel (OS) gives that request by swapping out a page into swap space ( when there wasn’t enought space available in RAM).
