TeamViewer: Control remoto para Linux y Android

Ante de nada, quiero disculparme con todos los seguidores de Galigio por la falta de Post en Castellano, espero poder volver a contribuir con mi granito de arena y compartir mis ideas. Bueno volviendo a lo nuestro, os quiero hablar del programa TeamViewer.

Hace tiempo estuve mirando para poder efectuar el aceso remoto entre mi PC y el PC de un amigo, ambos con Linux; desafortunadamente hay que reconocer que es posible pero no de una forma muy rápida y sencilla, el programa LogmeIn que era una de los disponible funcionaba solo con Windows y MAC también. Afortunadamente hace unos meses estuve investigando otra vez y pude averiguar que TeamViewer está disponible para Linux, Mac, Windows y también para Smartphones. La versión para Linux está disponible en diferentes paquetes: deb 32/64 bit, rpm 32/64 bits y también tar.gz; para Smartphone está disponible para Android, iPhone e iPad. Yo que uso Kubuntu he instalado la versión deb y también la he instalado en mi Smartphone Android.

Tengo que reconocer que funciona muy muy bien, desde mi teléfono puedo entrar en el escritorio de mi PC sin ningún problema y funciona muy rápido sin quedarse colgado. También he hecho una prueba entrando en el portátil de mi hermana mientra ella estaba en su casa y yo en la mía, todo muy bien, he podido efectuar una asistencia remota en su portátil e ayudarla con algún problemita que tenia. En fin, puede que no os cuente nada nuevo pero os aconsejo de probar esta aplicación porque seguro que siempre pude venir bien para diferentes usos. os dejo el enlace a su pagina Web.

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

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…).

How to Install Sopcast for free live TV in Ubuntu

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.

July, 6: how to censor the web. The Italian way…

Since this week, the Italian Authority for Communications, when a copyright violation is just reported (not proved by a Court as in all the other countries), can remove or inhibit any Italian or foreign website by blocking the IP address or the Domain Name Systems. This new regulation (not a law) actually represents a violation of the Net Neutrality.

How to Boot Ubuntu from USB

When it comes to the most recent generation of computers, there is an option to start an operating system right from a USB stick, without an actual installation process. This may be an option to use or test a different operating system without affecting in any way the one that is already installed.

Starting from version 8.10, Ubuntu can be installed on a USB stick in a more easy way by every single user, regardless of their knowledge in Linux. To perform the installation, the user must have a version of 8.10 or later on CD and a USB stick with a capacity of at least 700 MB free space available, but this can vary according to the version of Ubuntu that you want to use for this process.

To install Ubuntu on the USB stick, you can simply boot the Live CD mode of Ubuntu or alternatively, if already installed on your on your system, you can follow the following simple procedure to do this, which is described in some basic steps below.

First of all, you need to access the Ubuntu menu bar, via System> Administration, choose Create a USB startup disk.

At this point, you will be asked to specify the source disk image of Ubuntu. If you have the Ubuntu CD in optical drive, it should appear in the list and will be selected. Otherwise, click Other and specify the location of the image. The .iso format will do it, but other versions may work as well.

When completed, you can use the stick on any computer that can boot from such units. Just tell the computer’s BIOS to use this option and restart the respective machine. The same procedure can be applied for the any distribution of Linux, so this is a helpful tutorial for everyone. AddThis

CD Burning Applications for Ubuntu

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.

Including a Ubuntu Machine into a Windows Domain

One of the great problems of interoperability between Linux and Windows has been the impossibility of Linux systems for joining a Microsoft Windows network. Subsequently, several standards to achieve this were developed over the years (see Samba), but they were far from offering normal user the chance to achieve this easily.
The infrastructure of many companies around the world, of all sizes, also relies on the use of a Windows domain. In all companies, one priority always stands out. That is to reduce information costs and expenses. Because of this, many of them have opted for the use of computers with Linux operating systems. But in many cases their integration into Active Directory environments was a problem.
Recently, a new tool was created to facilitate the full integration of a Linux system in an AD environment. And as far as today, it seems very promising. Thanks to likewise-Open5 (http://www.likewiseopen.org/), the difficulty of integration is almost null.

The following lines will illustrate the inclusion of Ubuntu in a Windows domain via likewise-Open5.

Installation

Likewise-Open5 Installation process is very simple. It can be done both through the graphical environment and command line. We will use the second variant. Therefore, a new terminal window must be open, in which you specify the following command:

sudo apt-get install likewise-open5

This command should resolve all the dependencies necessary to prepare the machine to be integrated in the Windows domain.

Adding a new machine

To actually add the machine, specify the following command in the terminal window:

sudo domainjoin-cli join domain used

Where DOMAIN is the area used for integrating the machine, and USER is the username that has the corresponding rights. You will be asked for your user password, and once successfully logged in, you are officially added the desired machine. AddThis Flattr this

How to open PDF files (and other formats) through Mozplugger on Ubuntu

This article comes as a useful help for all Linux (Ubuntu) users, which will be presented with a new way of opening PDF files in the browsers compatible with this operating system. First of all, most of you probably know that Google Chrome is capable of doing this by default, without the user being required to make a particular setting.

However, Firefox does not currently have this built in feature, so it needs some help (usually in the form of a plugin) in order to open the PDF files you download or see online. In addition to the official plugin from Adobe (which contains numerous bugs and can sometimes be really annoying because if its way of loading PDFs), there is the option known under the name of Mozplugger. This is actually a plugin that allows the integration of different applications with the Firefox browser so that it can open some files not recognized automatically by default. If you want to install Mozplugger, the following simple steps are required and can be done by anyone.

After installing Mozzplugger, the following text muse be written in mozpluggerrc:

application / pdf: pdf: PDF file
application / x-pdf: pdf: PDF file
text / pdf: pdf: PDF file
text / x-pdf: pdf: PDF file
application / x-postscript: ps: PostScript file
application / postscript: ps: PostScript file
repeat noisy swallow (Evince) fill: Evince “$ file”

After making these changes, a restart is totally recommended. If you do not restart your browser right after that, changes might not take the desired effects. You will surely enjoy everything this great plugin has to offer. Not only will you be able to read PDFs directly in your browser, but there will also be some extra formats that you never thought they could be read directly from Firefox. AddThis
