Install Conky system monitor for Linux and configure it in few basic steps

Conky is one of the most powerful and versatile system monitors for Linux desktops. It allows you to monitor and display all the information about your hardware, top processes, network, emails and more. At the moment more than 300 different feature has been built for Conky and searching on the web you always find the perfect feature already developed by someone.

– Installation on Ubuntu:

in Terminal run: sudo apt-get install conky

– Configuration:

In Terminal run: sudo nautilus

Go to File System: /etc/conky/conky.conf

Save a copy of the original conky.conf in another location and open the original file with Gedit Text Editor

First of all change: own_window yes to own_window no

Choose your preferred alignment (some samples below…):
alignment top_right
or
alignment middle_right
or
alignment bottom_right

Play with: update_interval 1.0
and change the interval value till you find the right ratio to obtain the best speed for you (in my case it was 0.80).

Add this line to eliminate any flickering:
double_buffer yes
but, on some computers, all the icon on your desktop will be hidden and you need to use (move) the mouse to discover them if you will not add this parameter: own_window_type normal

Add, as last line (or in other position if you prefer):
${color red} ${cpugraph} to have a clear graph about cpu (obviously you can choose the color you prefer)

Run Startup Applications in System –> Preferences

CD Burning Applications for Ubuntu

2 Replies

There are not many applications for recording optical media under Linux. On the other hand, applications for Windows that allows a user to write a CD or DVD are numerous, but the most important difference is that those available on Linux are free and / or open source, with some exceptions. But all have basically the same purpose – to write or copy a disk.

In the world of Linux, the most common applications for burning optical media are usually pre-installed with the operating system chosen by the user. If not, they can be downloaded and installed easily on almost any platform.

Here are some of the most common such programs for Ubuntu:

Applications for Gnome / GTK

Brasero

Brasero is one of the most popular tools in the world of burning CDs. It usually comes pre-installed in most distributions that use Gnome. Brasero provides the user with a very friendly and simple interface while keeping all the important features needed by a user. Brasero is an application that requires minimal resources, providing maximum functionality, all integrated in one intuitive interface.

GnomeBaker

GnomeBaker is another GTK application with the same functionality as Brasero, but with a different interface. GnomeBaker gives the user an interface similar to Nero and K3B. The difference in use depends on the visual tastes.

X-CD-Roast

X-CD-Roast is an application to burn discs with its basic functions, but comes with a relatively primitive interface. Many users might find its interface as hard to use.

KDE Applications

K3B

K3B is probably one of the most popular programs available in the Linux world. It has many advanced features and options that would satisfy most users of such a program. It is available for both KDE and Gnome. Generally, K3B is regarded as the Nero of Linux.

The following system recovery tools will be useful to you if you are facing problem of data loss or if your system is simply crashing. It is advisable to burn copies of these tools much before any disaster strikes.

Open Source and Free approach:

G4L aka Ghost for Linux is one of the system recovery tools that is mainly a cloning and hard disk and partition imaging tool. This tool is similar to “Norton Ghost”.

Ideally, of the several tools described above it is advisable to use the most suitable tool for your needs. The tool that will be most useful during a crisis like a crash or server failure will be a better tool.

The Ultimate Boot CD is one of the system recovery tools which will be very helpful when you want to run CDRom-based diagnostic tools thereby consolidating as many diagnostic tools into one bootable CD as possible.

This is many steps ahead than many of the other recovery tools. Moreover it gives you the flexibility of booting your system with a USB memory stick.

Knoppix is one of the system recovery tools which is essentially a bootable CD with GNU/Linux software. It ensures automatic detection of hardware and supports a wide range of devices like sound cards, most of the graphic cards, USB and SCSI devices and other peripherals. It can be used as an educational CD, a Linux demo or for system recovery purposes. Alternatively it can be used as a commercial platform for software demos. There is no need to install anything on the hard-disk as the CD is capable of storing 2GB of software installed in it. Thus this tool is a truly multi-purpose recovery tool.

Proprietary solutions:

Amazon’s Kindle a popular portable e-book reader device, lately made Kindle for PC application that allows you to download and have books on your computer rather than having a portable e-book reader device. There’s only Kindle Windows version but the nice thing is you can have this application in Linux.

Install this with Wine HQ software loader and proceed to the normal installation, the same thing that you do in Windows environment.
Note:

– Configure Wine first and add Kindle for PC as an application and make it run in Windows 98 mode

– If it won’t work, change to other mode

– When it opens successfully you have to input you Amazon email add and password to register the software.

But, please, don’t forget that if you prefer open source software, you can directly use Calibre, a powerful free software we posted a while ago.

Rediscover Prism by Mozilla (Ubuntu, MAC and Windows tips)

1 Reply

In 2007, when Prism was launched, there were some enthusiastic reviews about this application. Then the widget era began and Prism popularity decreased. Anyway, Prism is still a powerful application for all that people who desire to run their more often used web application saving RAM and CPU resources. Prism, based on XULRunner, is multi platform, easy to use and very flexible. To use it on Ubuntu you can launch the Terminal and type:

sudo apt-get install prism

or using the Synaptics Package Manager (System —> Administration —> Synaptics Package Manager). Then go to Applications —> Internet —> Prism and a small windows appears. Now, fill in all the required information: the web application URL, the name you prefer, settings and do not forget to click on the Desktop shortcut option. At this point you will find a new rough icon on your Desktop with the name you chose. The first time you use it, with the right mouse button click on it and go to Properties —> Permissions and Allow executing file as program. If you want to change the icon you have to click on it (with the right mouse button), go to Properties —> Basic and choose your favorite icon clicking the icon on the upper left corner. If all are steps are annoying for you, it is possible to use Prism as add-on for Firefox. In this case, on Firefox, go to Tools —> Add-ons —> Get Add-ons and type Prism on the search bar. You will install Prism as a simple add-on for Firefox. Now, you can automatically generate a Prism application just clicking on Tools —> Convert Website to Application when you are in the web application page.

On Windows or MAC we suggest to download the standalone package directly from the official web page or install Prism as Firefox add-on following the same steps we described for Ubuntu. If you use the Prism standalone package you have to decompress it in your favorite location. For Windows users: when you set up a new Prism application, try the tray menu option but do not forget to click on the Desktop shortcut or you will not be able to find again the application after you close it.

In my experience, Prism is really useful with all the Google web applications, with Zoho services and Pandora. Try and enjoy it!
