The Bolivian Diary

Ernesto Guevara de la Serna commonly known as Che Guevara, El Che or just Che was an Argentine born Marxist revolutionary, political figure, and leader of Cuban and internationalist guerrillas.



As a young man studying medicine, Guevara travelled roughrough throughout South America, bringing him into direct contact with the impoverished conditions in which many people lived. His experiences and observations during these trips led him to the conclusion that the region's socio-economic inequalities could only be remedied by socialism through revolution, prompting him to intensify his study of Marxism and travel to Guatemala to learn about the reforms being implemented there by President Jacobo Arbenz Guzmán.



While in Mexico in 1956, Guevara joined Fidel Castro's revolutionary 26th of July Movement, which seized power from the regime of the dictator General Fulgencio Batista in Cuba in 1959. In the months after the success of the revolution, Guevara was assigned the role of "supreme prosecutor", overseeing the public show trials and executions of hundreds of military and civilian leaders associated with the previous regime. After serving in various important posts in the new government and writing a number of articles and books on the theory and practice of guerrilla warfare, Guevara left Cuba in 1965 with the intention of fomenting revolutions first in Congo-Kinshasa, and then in Bolivia, where he was captured in a military operation supported by the CIA and the U.S. Army Special Forces. Guevara was summarily executed by the Bolivian Army in the town of La Higuera near Vallegrande on October 9, 1967.

After his death, Guevara became an icon of socialist revolutionary movements and a cultural icon worldwide. An Alberto Korda photo of him has received wide distribution and modification, appearing on t-shirts, protest banners, and in many other formats. The Maryland Institute College of Art called this picture "the most famous photograph in the world and a symbol of the 20th century.

The Bolivian Diary

Also removed when Guevara was captured was his diary, which documented events of the guerrilla campaign in Bolivia. The first entry is on November 7, 1966 shortly after his arrival at the farm in Ñancahuazú, and the last entry is on October 7, 1967, the day before his capture. The diary tells how the guerrillas were forced to begin operations prematurely due to discovery by the Bolivian Army, explains Guevara's decision to divide the column into two units that were subsequently unable to reestablish contact, and describes their overall failure. It records the rift between Guevara and the Bolivian Communist Party that resulted in Guevara having significantly fewer soldiers than originally anticipated. It shows that Guevara had a great deal of difficulty recruiting from the local populace, due in part to the fact that the guerrilla group had learned Quechua rather than the local language which was Tupí-Guaraní. As the campaign drew to an unexpected close, Guevara became increasingly ill. He suffered from ever-worsening bouts of asthma, and most of his last offensives were carried out in an attempt to obtain medicine.



The Bolivian Diary was quickly and crudely translated by Ramparts magazine and circulated around the world. There are at least four additional diaries in existence — those of Israel Reyes Zayas (Alias "Braulio"), Harry Villegas Tamayo ("Pombo"), Eliseo Reyes Rodriguez ("Rolando") and Dariel Alarcón Ramírez ("Benigno") each of which reveals additional aspects of the events in question.

What is called Cookies?


HTTP cookies sometimes known as web cookies or just cookies, are parcels of text sent by a server to a web browser and then sent back unchanged by the browser each it accesses the server.

What is the use of Cookies?

HTTP cookies are used for authenticating, tracking and maintaining specific information about users.

The term "Cookie" is derived from "magic cookie" a well known concept in UNIX computing which inspired both the idea and the name of HTTP cookies.



What is the main purpose of Cookies?

Cookies are used by Web servers to differentiate users and to maintain data related to the user during navigation, possibly across multiple visits.

Cookies were introduced to provide a way for realizing a "shopping cart" a virtual device into which the user can "place" items to purchase, so that users can navigate a site where items are shown, adding or removing items from the shopping basket at any time.


But guys, There in no connection between the picture and the concept ;-)

Microsoft surface



What is Microsoft Surface?

Microsoft Surface, the first commercially available surface computer from Microsoft Corporation, turns an ordinary tabletop into a vibrant, interactive surface. It provides effortless interaction with digital content through natural gestures, touch and physical objects. Surface is a 30 inch display in a table like form factor that’s easy for individuals or small groups to interact with in a way that feels familiar, just like in the real world. In essence, it’s a surface that comes to life for exploring, learning, sharing, creating, buying and much more. Soon to be available in restaurants, hotels, retail and public entertainment venues, this experience will transform the way people shop, dine, entertain and live.

How does Surface works?

At a high level, Surface uses cameras to sense objects, hand gestures and touch. This user input is then processed and the result is displayed on the surface using rear projection.



What is Surface computing?

Surface computing is a new way of working with computers that moves beyond the traditional mouse and keyboard experience. It is a natural user interface that allows people to interact with digital content the same way they have interacted with everyday items such as photos, paint brushes and music their entire life with their hands, with gestures and by putting real world objects on the surface. Surface computing opens up a whole new category of products for users to interact with.

What are the key attributes of surface computing?

Surface computing has four key attributes:

Direct interaction. Users can actually “grab” digital information with their hands and interact with content by touch and gesture, without the use of a mouse or keyboard.

Multi-touch contact. Surface computing recognizes many points of contact simultaneously, not just from one finger, as with a typical touch screen, but up to dozens and dozens of items at once.

Multi-user experience. The horizontal form factor makes it easy for several people to gather around surface computers together, providing a collaborative, face-to-face computing experience.

Object recognition. Users can place physical objects on the surface to trigger different types of digital responses, including the transfer of digital content.


How does Surface benefit customers?

Microsoft Surface will break down the traditional barriers between people and technology, providing effortless interaction with digital content. Similar to the way ATMs changed how people got money from the bank, Microsoft is changing the way people will interact with all kinds of everyday content, including photos, music, a virtual concierge and games. Common, everyday tasks become entertaining, enjoyable and engaging, alone or face-to-face with family, friends or co-workers.

Gadgets




A gadget is a device or an appliance that has a useful specific practical purpose and function but is often thought of as a novelty. Gadgets are invariably considered to be more unusually or cleverly designed than normal technology at the time of their invention.

Gadgets are sometimes also referred to as gizmos. In some circles the distinction between a gadget and a gizmo is that a gizmo has moving parts, whereas a gadget need not have them. For example, a digital watch would be a gadget, while an analog watch would be a gizmo. Thus a gizmo is essentially a mechanical gadget.

Programmable gadgets

Most of the modern gadgets belong to this category. These gadgets are invariably based on a microprocessor and often have flash memory. They use embedded software which controls their functions. Such gadgets are found not only in the pockets of gadget freaks, but also in their cars and homes. Some examples of gadgets in this category are notebook computer, mobile phone, iPhone etc.
