Increase swap memory without partitioning or after install Ubuntu/Mint/Debian

Swap memory is very important for every distro. on hibernate system save all data from ram to Swap. Swap space is used when your system decides that it needs physical memory for active processes and there is insufficient unused physical memory available. If the system happens to need more memory resources or space, inactive pages in physical memory are then moved to the swap space therefore freeing up that physical memory for other uses.

What happen if you have already installed your system without swap partition? yep you can create a swap as a file.

1. create a file for swap “sudo fallocate -l 2048m /mnt/swap_file.swap” //2048 for 2GB it based on your requirements
2. Change the permission “sudo chmod 600 /mnt/swap_file.swap
3. Format the file for swapping device “sudo mkswap /mnt/swap_file.swap
4. Add swap “sudo swapon /mnt/swap_file.swap
5. Edit fstab file “gksudo gedit /etc/fstab
6. Add this line at the end of the file “/mnt/swap_file.swap none swap sw 0 0
7. Reboot your machine “sudo reboot

Do you fed up with internet privacy? Past years tracker were used spyware, virus, malware were used to track you but now trends have been changed, yes they using JavaScript, cookies for spying. Millions of people were tracking your activities via internet. Ads were following you everywhere. Many people moved to Linux based machine so they don’t need antivirus, malware function etc. Is all Linux users are secure? no, because tracker use your browser for data collecting. So you should use some security add ons in your browser. i would like to suggest some add ons are follows.

1. Ghostery  – Monitors third-party trackers on sites. Ghostery will only show you which trackers are operating on the websites

2. AVG privacyfix – Helps lock down your Facebook and Google privacy settings.

3. Disconnect – Blocks trackers from popular sites.

4. HTTPS Everywhere  –  Redirects to secure (HTTPS) versions of sites where possible.

5. DuckDuckGo – Search anonymously.

6. Adblock Plus – Blocks intrusive ads.

7. DoNotTrackMe – It blocks third-party trackers on sites. ( Firefox, Chrome )

8. Lightbeam for Firefox – See who’s tracking you online.
