We all know that on Windows dragging a file while right clicking on it opens a menu and we can copy/move it there. Well, in Ubuntu you cannot drag & drop a file with right click. BUUUUUUT:
Try middle-click+drag… This will happen:

Have you ever tried converting multiple images to a PDF file? Under Windows you need to search for a software, test them, get the best (preferably FREE) and so on…
In Ubuntu this is so simple that you will laugh. It’s like you gently say to your computer:
Man, please make a PDF from these images :)
You don’t believe me? Open a terminal, go to a folder in which you have the images that need to be converted in PDF (I will suppose here the images are PNG files) and type this command:
convert *.png my_filename.pdf
And then wait until it finishes the job! That’s all…
I wanted to test some Emerald themes yesterday, but didn’t knew how to do it (funny, indeed).
So I started digging and managed to use them. In case you are in the same situation here is what you need to do:
You need to be using Compiz.
Install Emerald:
sudo apt-get install emerald libemeraldengine0
Download some Emerald Themes (from here for example) and then go to System > Preferences > Emerald Theme Manager, click Import and select your file (the one you’ve just downloaded)

To make your windows (not the OS :p) use Emerald, go to System > Preferences > CompizConfig Settings Manager and enable “Window Decoration”, then click it and under “Command”, enter:
emerald —replace
Then to run it for the first time, press Alt + F2 and type:
emerald —replace
To make Emerald start by default, go to System > Preferences > CompizConfig Settings Manager then select Effects » Window Decoration then in the “Command” field enter:
emerald —replace
To disable Emerald:
compiz —replace

It’s so simple to create an ISO from your CD/DVD. Just run this:
cat /dev/scd0 > /path/to/your/image_name.iso
This is the “quick” method. If it’s not working (for me it worked), just open System Monitor (menu: System » Administration) and see there the device name for your CD/DVD Rom:

Now re-run your command replacing /dev/scd0 with the device nqme from System Monitor:
Ex: cat /dev/sr0 > /path/to/your/image_name.iso
… or to be more specific - How to convert BIN / CUE to ISO in Ubuntu
First install bchunk (a UNIX/C rewrite of the BinChunker program)
sudo aptitude install bchunk
After the installation is completed, run this command to convert BIN / CUE to ISO in your Ubuntu.
bchunk image-name.bin image-name.cue new-image.iso
You’ll see a progress bar and in few seconds/minutes your BIN / CUE image will be an ISO ready to be mounted. (For mounting ISO I use Furius ISO Mount - you can fin it in Ubuntu Software Center).
In Chrome click on the wrench symbol, then click on Preferences and under Personal Stuff (on the bottom) click the checkbox that says use system title bar and buttons!

That’s all!
Well, I needed to move the buttons from right to left, but this tutorial explains everything excellent :)
/# for hdd
sudo apt-get install hddtemp
sudo hddtemp /dev/sda
/# OR sudo hddtemp /dev/hda
/# processor
cat /proc/acpi/therm//temp*
Please notice that for the temp of the HDD in this example it’s used a program called hddtemp (see first line - we’re first installing it and after that we’re using it - so don’t run the command without first installing the small hddtemp app)
If you don’t want the command line version and want something that “sticks” on your desktop, there is a program like this (actually an applet) called Computer Temperature Monitor - (web page) - it has alarms, logs - it’s pretty nice :)

One thing though - they say “Computer Temperature Monitor is a little applet for the GNOME desktop that shows the temperature of your computer CPU and disks on screen”. However, I can only access the CPU temperature, I cannot see in the settings any option for displaying the HDD temp (it’s true, I didn’t loose so much time on this).
I’ve always wanted to have my Google Calendar appointments in Ubuntu Clock.
So, today I finally search for a way to do this and found this. It’s so simple it made me laugh thinking I’ve always postponed this thinking are multiple steps to follow :)
So, let’s stop talking and get to the “real stuff”.
Go to your Google Calendar Settings, click on your calendar and then from the bottom of the page copy the ICAL link for your Private Calendar.

Open a Terminal and run this command:
/usr/lib/evolution-webcal/evolution-webcal ICAL_URL_COPIED_BEFORE
You will see a window like this:

Choose the refresh interval, your calendar color and click Subscribe.
That’s all. Now your events will appear in your clock under Appointments:
