To change your hostname, you’ll need to edit /etc/hostname file with
The file content is very simple. It contains the current hostname and all you need to do is to replace it with the new one, save and exit
After you save the changes, open /etc/hosts file and replace the current hostname with the new one near 127.0.1.1 IP address.
Save file and exit.
Now, enter the next command
sudo hostname new-hostname
Your computer’s hostname will be changed immediately. (The change won’t appear in the terminal until you reopen it again)
This method will work on all Debian based distros (Ubuntu, Kubuntu, ….)

I’m using Mint Linux and I noticed that the Bluetooth adapter is always on (I turned it off in the previous session). I’m using Bluetooth from time to time, but I don’t like to see it on when I don’t need it. Besides, it wastes battery.
You can turn it off per session (as I did), but next time it’s right back on which annoys me. As I can see, I’m not the only one who is affected with this.
The solution is set InitiallyPowered parameter to false.
sudo nano /etc/bluetooth/main.conf
Search for the entry:
and change the value to:
Next time you boot, it should be down.
In case this doesn’t help, try to turn off bluetooth service by adding “/etc/init.d/bluetooth stop” inside /etc/rc.local file (before the “exit 0” line)
Google announced plans to discontinue 32-bit Google Chrome for Linux and it has. On some 64bit Ubuntu based systems (Mint/Kubuntu/Xubuntu,..), during update process you may notice the next error:
“Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release Unable to find expected entry ‘main/binary-i386/Packages’ in Release file (Wrong sources.list entry or malformed file)”
To fix this error you’ll need to make some changes in google-chrome.list
Open /etc/apt/sources.list.d/google-chrome.list file and add [arch=amd64] before “http”
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main
Do not edit or replace any other text in this file. Save the changes and refresh your package list with
The “failed to fetch” APT error should no longer appear
Bad news for Mint users who downloaded ISO files few days ago (20th Feb)…
Some dude found the way to replace the official Mint 17.3 Cinnamon ISOs with the cracked ISOs (with backdoor inside)
More details can be found here: http://blog.linuxmint.com/?p=2994
Also, as Clem announced, the forum database was compromised and you should change your password on all sensitive websites as soon as possible (in case you used the same password on other sites)

In case you’re using MySQL Workbench for creating dumps please keep in mind that version 6.3.5 has one annoying bug.
After update, the first time I tried do create dump, the complete process failed with the next error:
mysqldump: [ERROR] unknown variable 'delayed-insert=FALSE'
As I can see, this error occurs on various systems (Windows / MAC / Linux) and it was fixed once (6.1.x was also affected – LINK)
For now, you can only apply temporarily fix:
Open file (as root) wb_admin_export_options.py (located in /usr/lib/mysql-workbench/modules for Ubuntu/Mint/Debian distros)
Find the line
"delayed-insert":["Write INSERT DELAYED statements rather than..."
and insert # at the begin of this line (to comment it out)
Save file and restart Workbench. Check the Advanced option and note that this option is not available
Note: Windows users
For 32bit systems, wb_admin_export_options.py is located in C:\Program Files\MySQL\MySQL Workbench XXX\modules
For x64 systems, wb_admin_export_options.py is located in C:\Program Files (x86)\MySQL\MySQL Workbench XXX\modules)
The bug fix is easy to apply but it was announced months ago we’re still waiting for update… So shame…
