At the end I decided! I want to uninstall OpenOffice on my Ubuntu 10.04 LTS and substitute it with an always updated LibreOffice. After some researches on the web I decide to develop my own procedure to be sure that LibreOffice will be always updated with the last available edition.

First of all it is necessary to remove OpenOffice:

- go to System –> Administration –> Synaptic Package Manager –> Quick Search and type OpenOffice

- Mark for Complete Removal all the installed OpenOffice software and Apply  your choice, then exit the program

Now, open Terminal and add the PPA repository:

sudo add-apt-repository ppa:libreoffice/ppa

Update the system:

sudo apt-get update Last but not least, go back to Synaptic Package Manager –> Quick Search and type LibreOffice

Select the LibreOffice software and all the add-ons you prefer then Apply  your choice.

That’s all! You have the last version of LibreOffice installed on your Ubuntu 10.04 LTS and you are also sure that Synaptic will update the packages when a new version is available! AddThis

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)

For automatic start of Conky at startup, please follow the following instructions:
Run Startup Applications in System –> Preferences
Click on Add and save after updating the following instructions
Name: Conky
Command: /usr/bin/conky

Restart Ubuntu to check your new Conky “applet”

Link to Conky: http://conky.sourceforge.net/

For more info about Conky’s variables: http://conky.sourceforge.net/variables.html

Find online some pre-compiled Conky configuration files, searching, for example, on: http://gnome-look.org

The dawn of Morpheus’ era. Google’s supremacy and your privacy: short considerations about Google+ July 18, 2011

In the last days, I tested Google+ and it really works! It’s fast, well-organized with a really intuitive graphical interface and, for the “first time”, I was able to start conversations with different groups without worrying to say something inappropriate to the wrong person. The problem is that it wasn’t the very “first time” I had the possibility to share a conversation because, for some months, I was one of the testers of Diaspora, an open-source project, which was financed through kickstarter.com

Diaspora is a start-up project in its alpha release and the most interesting supported features are the https streaming and the possibility to create separate conversations with preselected groups. During the past months Diaspora has not  grown fast but this kind of timeline is not unusual considering the number of developers involved, the financial capital used and all the different problems that a start-up has to solve during the first year of existence. The Diaspora’s real added value was the idea of a more secure social media through https and dedicated conversation shared between homogeneous groups of people.

On the contrary Google hasn’t had this kind of problems while developing a similar project, Google+. Anyway Google is so well structured and financially powerful that can reach the goals in a very short time if someone, at Mountain View, really believes on the future possibilities of a project. In few words, this is the natural dominance of a big player in an imperfect market where the start-up can be annihilated by a faster and richer competitor which is able to use more human resources and capitals.

I personally believe that Google, in such a way, has contaminated the natural software “diversity” growth and has too easily prevailed over the Diaspora’s guys. I am not talking about copyrights or trademarks which have often damaged the software development, I am talking about software evolution, the “natural” selection that allows small groups of people with better ideas to survive and prevail over the bigger companies. We cannot be sure that, after the completion of Diaspora, new valuable projects wouldn’t have springed from that team. Perhaps it’s time to critically ask ourselves if Google has become too big and too powerful over the web and if we need a new generation of laws or rules just to perimeter it (not to censure its works or split the company).

Back to Google+, I can strongly affirm that all the features I tested were well programmed and extremely intuitive to use. Moreover, Google+ integrates many other Google products (e.g. Picasa, YouTube, Voice, etc..) and you can share a lot of contents directly with the right people using the, now “famous”, Circles feature.

But at this point, we need another old -no software related- question mark. How many information about our lives are stored in Google servers? All the Google online software are successfully principally due to their high level of usability. None force you to use Google’s products, you are 100% free to decide but usually you have specific accounts to manage your photographs, favourite RSS, documents, phone directory, emails and now also your friends, family and more… All these information profile you and your personal attitudes better than ever. Using the right mathematical function, Google potentially has an accurate profile of you than no one else and sometime it is reasonable to believe that Google knows us better than we do.

In this prospective the “digital identification” card someone proposed some years ago to better regulate the web and check the people online activity, sounds prehistoric. The natural evolution of the net, connected to the lack of a real liberal regulation, has created a “nice” superpower company that potentially has the possibility to share our most intimate data with third parties influencing in a way or another our destinies. Can the privacy disclaimers we accept with each Google service protect our data in a bullet-proof way? Personally I have some little doubts!

On the other hand, during the last year we assisted to the dawn of more decentralized online services (www.yacy.net, www.faroo.com, www.majestic12.co.uk, etc..) and payment systems (www.bitcoin.org) which are able to guarantee a more efficient encrypted privacy. To  extremely simplify the concept it is possible to say that these new technologies represent a possible future horizon that will be developed in few years. Consequently, it is reasonable to predict that two parallel Internet will exist in the near future.

The first is the logical evolution of the web we know today with a more “efficient” control developed by Governments and specialised “agencies”. The second will be something near to what we watched in the Matrix saga. A semi-secret Internet, developed by unknown “experts” where the privacy will be one of the most valuable elements and where we will use a new generation of dynamic encryption software. If we consider that nowadays it is technically possible to build low-cost telecommunication satellites, the only residual barrier for the creation of this new web is represented by the cost of the vectors to bring them into the space. Waiting for a cheap orbital launcher, new technologies have been experimented to build alternative webs. The transmission of encrypted computer data through the radio frequencies is one of the most interesting projects. But this is another story also because we should consider the risks related to a second new encrypted Internet if not used in a proper way…

To conclude, let me say that Google’s people are the best but now, it is time they start thinking a little bit less about online software or visionary technologies and much more about the potential social and freedom risks of their work. There are not precise rules about these topics because just few politicians have a real knowledge about the “digital frontier” and for this reason they have the terrific possibility to regulate themselves in the best way and be really transparent. History rules, when there is not effectiveness regulation, there is the risk that, sooner or later, lobbies persuade politicians to law in a wrong way. If we think about what happened in the last thirty years we can focus our attention on specific tragic events which allowed Parliaments to overreact and chain our civil rights and our privacy in a way that has not roots in our democratic societies.

On the contrary, with new democratic and “illuminated” rules or self-reforms, honestly created by real experts, there will less needs for a parallel Internet and perhaps the dawn of Morpheus’ era will be postponed for a while. At the moment we can only hope that Google people are not became too old to consider that they could change their point of view. The current Google technological path is just one of the many they can develop. Now this path seems to be efficient and, of course, profitable but perhaps the near future needs something different and less dangerous for our privacy and civil rights… (to be continued, sooner or later…).

Sopcast represents one of the most popular technologies for live TV streaming, being based on the famous p2p system. However, until recently, there was no version of this software for Ubuntu and Linux in general. But now every single user can enjoy live TV right on their desktop or laptop computer with this absolutely amazing program.

In order to install Sopcast on your machine, here is what you need to do:

1. Open a new terminal. This is a classic step and is used in most of the installation processes you will encounter in Ubuntu.

2. In order to add Sopcast to Synaptic (the package administrator software integrated into Ubuntu) you will need to type the following command:
sudo add-apt-repository ppa:jason-scheunemann/ppa

3. The next step is related to the update of the sources list. This can be done with the following command, which needs to be typed into the same terminal in order to achieve the right effects:
sudo apt-get update

4. Now you will need to run Synaptic in order to finalize the process. This is usually done through the System menu (System -> Administration -> Synaptic). Alternatively, you can use the following simple command:
sudo synaptic

5.  Look for the Sopcast package and install it. A very important step at this point is to not forget about all its dependencies. If you do not install everything, then Sopcast will not run correctly or not at all.

This is basically all you need to know if you want to install Sopcast on your machine. Whenever you need to run the player you can find it in the Application menu -> Multimedia -> Sopcast. You will surely enjoy the great variety of the channels available for every user through this system.

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”. The images created are compressed optionally and transferred to a FTP server instead of opting for cloning locally. 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. Since you can now boot from USB memory devices a script you can run “Ultimate Boot CD” from USB memory stick and a script on the script on the CD will enable you to boot newer systems from your USB sticks. 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:

O&O Disk recovery: This software tool scans every portion of your hard-disk, digital camera or memory card for lost files. It is so effective and reliable that it is possible to reconstruct data even when files systems have been destroyed or formatted. More than 350 types of files like music formats, word documents, movie, graphics, Excel workbooks, photo and access databases can be recognized, reconstructed and restored.

SuperDuper is one of the system recovery tools makes recovery effortless as it creates a completely bootable backup effortlessly. The strengths of this software are that it is user-friendly, easy to use with a built-in scheduler that it makes backup automatically. Moreover it performs well independent of the processor that is both on Power PC Macs as well as Intel PCs. It is particularly useful when your software application with the latest update is not working or when your hard drive begins to make noise. It is also very handy when you want to restore a stable copy of your system though you do not want t lose your existing system files or cases like this. AddThis mp3 link

Several open source tools have evolved in the past and have become popular with the developers too.  These tools have gained popularity not only because they come free but because of the ease to work with and the features.  First let us see some code editors:

- Aptana:  It is a free, JavaScript focused development environment, cross-platform and open source for building Ajax applications.  It supports HTML, JavaScript, CSS languages, FTP/SFTP and has a powerful JavaScript debugger that can help in troubleshooting your code.

- Eclipse :  It is an open source software framework written mainly in Java.  It is an integrated development environment consisting Java development toolkit (JDK) and compiler (ECJ) for developing applications in Java.  Developers can extend its capabilities by installing plug-ins such as development toolkits for other programming languages written specifically for eclipse software framework.  Language packs for over a dozen languages are available.

- JEdit : It is a programmer’s text editor which has many hundreds of man-hours of development behind it. It is a java-based solution  and a cross-platform product  which can work on many operating systems like Windows, VMS, UNIX,  OX/2 and Mac OS X.

- NVU : It is a web authoring system for Linux desktop users, Macintosh users as well as for Microsoft windows and  is a competitor for similar products like Dreamweaver and Frontpage.  Nvu actually means new view and makes managing a website very easy.  Now even people without knowledge of HTML or technical expertise can create web pages and manage a website.

- Quanta Plus : It is a web development environment with a lot of features and is highly stable.   Quanta has a vision of achieving maximal user extensibility through the best architectural foundations, best, efficient design and natural use of code.

We shall see other tools in other posts. AddThis mp3 link

Get Kindle for PC to Ubuntu (if you really don’t like Calibre) January 10, 2011

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.
This is tested in Ubuntu 9 running Gnome. You can use different version of Linux, but first you must have Wine HQ installed to you computer. Then download the EXE file of Kindle for PC application in Amazon.
Install this with Wine HQ software loader and proceed to the normal installation, the same thing that you do in Windows environment.
Note:

- At your first run you won’t see anything at all

- 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. AddThis
