One of the most written and commented articles has to be Linux vs Windows (of course there are competitors like vim vs emacs) but none has been covered so much as Linux vs Windows. So, what am I going to write here which is not covered earlier in so many other posts. Well a little different perspective 🙂

Home page : Tracer Home page.
To install :
sudo dnf install tracer
Once you have done that, after every dns update/upgrade you would see a list of process’s that need to be restarted. If you want to find manually, then just :
sudo tracer
Was searching for this for sometime now, finally found it.
sudo yum install nemo sudo yum list nemo*
First just install nemo. Configure nemo not to interfere with default desktop and also make it default handler. So, here are the settings that would do it.
gconftool-2 --set /desktop/gnome/applications/component_viewer/exec --type 'string' 'nemo "%s"' gconftool-2 --set /desktop/gnome/url-handlers/trash/command --type 'string' 'nemo "%s"' gsettings set org.nemo.desktop show-desktop-icons false
Now, if you need more functionality in file manager then check the list of nemo packages from the output of second command of yum. It has plugins like file preview and so on. Install and enjoy.

sxiv is an alternative to feh and qiv. Its only dependency besides xlib
is imlib2. The primary goal for writing sxiv is to create an image viewer,
which only has the most basic features required for fast image viewing (the
ones I want). It works nicely with tiling window managers and its code base
should be kept small and clean to make it easy for you to dig into it and
customize it for your needs.
You can first set the bash mode to vi. This will enable some vim like features to bash. So, add this to .bashrc :
set -o vi
Once, you have done that then its time to get more out of the vi mode. First, check some things and set some interesting stuff.

zswap is already in the kernel and you can see the documentation in the kernel documentation. Here is the name of the file if you need:
/usr/share/doc/kernel-doc-$(uname -r)/Documentation/vm/zswap.txt
Here is the overview, in case you do not want to install kernel-doc
Overview:
Zswap is a lightweight compressed cache for swap pages. It takes pages that are

in the process of being swapped out and attempts to compress them into a
dynamically allocated RAM-based memory pool. zswap basically trades CPU cycles
for potentially reduced swap I/O. This trade-off can also result in a
significant performance improvement if reads from the compressed cache are
faster than reads from a swap device.
If you are using Linux (Fedora/Ubuntu or anything else) then you do get a lot of tools and one of them is cron. Very very useful. Just write some script that can do the task for you, put it in cron and forget it. So, here is a home grown way to schedule mails.
First, copy this script below:
#!/bin/bash - #=============================================================================== # # FILE: sched_mail.sh # # USAGE: ./sched_mail.sh # # DESCRIPTION: # # OPTIONS: --- # REQUIREMENTS: --- # BUGS: --- # NOTES: --- # AUTHOR: Amit Agarwal (aka), # REVISION: --- #=============================================================================== mailfile="~/mail" if [[ $(wc -l $mailfile|awk '{print $1}' ) -ge 5 ]] then to=$(grep ^To: $mailfile|sed 's/To: //') echo "Good to send mail... to = $to" sendmail -t <$mailfile echo "once mail is send, delete the contents of file" echo "sed -i '4,$ d' $mailfile" fi
Now, create a file called mail in your home directory, with the following contents:
