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…).

To enable remote desktop on a VirtualBox machine, you have to follow these steps:
VBoxManage modifyvm MachineName -vrdp
This command enables rdp on the virtual machine
VBoxManage startvm MachineName -type vrdp

It starts virtual machine, listening for rdp request on port 3389 (default port)
rdesktop-vrdp localhost

Connects virtual machine with rdp (You can use rdesktop too).
If you want to change rdp port, use this command:
VBoxManage modifyvm MachineName -vrdpport

Also, enabling authentication for rdp is possible:
VBoxManage modifyvm MachineName -vrdpauthtype null | external | guest

VBoxManage is the command line interface of the VirtualBox.
You can make these settings with GUI: Settings -> Remote Display -> Enable VRDP Server
If you want to use your virtual machine with vrdp only, you can use this command simply:
VBoxHeadless -startvm MachineName

Note: RDP server is not included in Open Source Edition of the VirtualBox. If you want to use this feature, you have to use closed-source edition. 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

LibreOffice vs. OpenOffice! What’s the difference? January 6, 2011

Since the end of September 2010, a group of German OpenOffice volunteers left definitively the project to join the The Document Foundation and develop a fork version of the famous free productivity platform now controlled by Oracle. After just few months we have LibreOffice: a (more or less) new cross-platform productivity software based on OpenOffice version 3.3 beta. We compared both the free suites and apparently we did not notice particular differences in features and tools. Also the graphic interface is similar between the two platforms and the buttons position is the same. At the moment LibreOffice supports less languages in its Linux and MAC OS X versions and it is not compatible with Solaris based PCs. Both the productivity platforms are able to use the OpenOffice extension library.  Consequently, it is clear that it’s too early to notice relevant technical differences between the two competitors but, for sure, something will show off in the next versions. In fact LibreOffice has been created to guarantee a vendor independent office suite which can be developed with no copyright software chunks. The goal is prestigious and we can only say, Good Luck LibreOffice! AddThis mp3 link Flattr this!

En estos días he estado buscando un programa que permita hacer Copias de Seguridad y que sea de uso practico, sencillo y muy intuitivo. Después de ver varios programas me he decantado sin lugar a duda para LuckyBackup. Para instalarlo es posible directamente desde los repositorios de nuestro sistema (Ubuntu y derivados) o directamente desde su propia Web y bajar la ultima versión 0.4.4 . Yo he instalado esta ultima versión y tengo que confirmar que es el mejor programa de Copias de Seguridad que he encontrado hasta el momento.

How to protect your profile and emails on Thunderbird 3 (Ubuntu and Windows instructions) October 25, 2010

On Thunderbird, the only way to be 99% sure nobody will read your emails is to save your profile on an encrypted folder (or disk partition) using e.g. TrueCrypt but if you are not concerned that you are under surveillance, you can simply use a quick and useful trick that allows Thunderbird to ask for the Master password every time you launch it.

In Ubuntu you have to follow two different steps. First of all, go to Edit —> Preferences —> Security —> Passwords and create your Master Password. Secondly, go to Edit —> Preferences —> Advanced —> Config Editor (click on “I’ll be careful, I promise”). Then in the filter bar, type password and change the parameter for mail.password_protect_local_cache to True. The next time you will launch Thunderbird nothing will be displayed (old and new emails) before you insert the correct Master Password.

If you are using Thunderbird on Windows you have to modify mail.password_protect_local_cache going to Tools —> Options —> Advanced —> Config Editor (click on “I’ll be careful, I promise”). Then, as for Ubuntu, in the filter bar type password and change the parameter for mail.password_protect_local_cache to True. AddThis mp3 link

UbuntuInstalling software on Ubuntu is really easy but sometimes we can have problems to uninstall it if we have not used the Package Manager (Synaptic till Ubuntu 9.04 and later through the Software Center) or a .deb package. To fastly uninstall all the software you do not need or you are not fond of, you can type in the Terminal:

sudo dpkg -r your_file

An alternative and powerful way is typing:

sudo apt-get remove your_file

(where your_file it is the name of the software you want to remove)

or, if you want to completely cancel also the configuration files:

sudo apt-get --purge remove your_file

If you want to check what software is installed on you Ubuntu you can use:

dpkg --list

and you will obtain a complete list of software and a very short summary for each package. AddThis mp3 link

Prey: a multiplatform, open source anti-thefth free software for laptops October 18, 2010

What about losing your laptop? Obviously the chances to find it and have it back are very few! But there are several software you can install on your laptop to trace the ip and geo-location of te laptop and with a bit of fortune you could find it. Prey is one of these programs you can use and it is particularly interesting because it is open source and free up to three laptops. After the download of the proper version for your OS (Linux, Windows, Mac OS X or Android) you have to run it on your machine and configure it through a very simple interface (on Ubuntu: Applications —> System Tools —> Prey Configurator). Do not forget to select Enable guest account and Wifi autoconnect to improve the possibilities to trace your laptop. You are also asked to provide an email account where you will receive the geo-location reports if your laptop is stolen. When you activate your Prey account do not forget to fill in the Configuration and Modules tabs. Personally we suggest to switch to ON the following commands: Auto update, Notify new reports and all the commands contained in the left column of the Modules tab. At this point, if your laptop is missed, you have to log in your on-line Prey account and, in the Configuration tab, switch the Missing option on YES. Since this moment, Prey software on your laptop is activated and will start sending reports to your email and to your Prey webpage. Last but not least, to better protect your laptop I suggest to hide or cancel the Prey Configurator icon from the OS menu (in Ubuntu: System —> Preferences —> Main Menu —> System Tools and deselect Prey Configurator).
