Free Software concepts to know

What is Free Software? Free software is a question of freedom, not price. To understand this concept, we must think in the meaning of free as in freedom of expression and not as in open bar of beer. By free software we mean the freedom of users to run, copy, distribute, study, change and improve the software. We are referring especially to four kinds of freedom for software users. The four basic freedoms are: Freedom 0: the freedom to run the program, whatever our purpose. Freedom 1: the freedom to study how the program works and adapt it to your…

Innovative Battery Technology Puts Flying Cars on the Horizon

Jet packs, robot maids, and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing (eVTOL) vehicles and designing and testing potential battery power sources. “I think flying cars have the potential to eliminate a lot of time and increase productivity and open the sky corridors to transportation,” said Chao-Yang Wang, holder of the William E. Diefender Chair of Mechanical Engineering and director of the Electrochemical Engine Center, Penn State. “But electric vertical takeoff and landing vehicles…

Unlocking the Potential of Blockchain Technology: Decentralized, Secure, and Scalable

Algorand uses a unique architecture developed by MIT Professor Silvio Micali to offer a decentralized, secure, and scalable blockchain. The Republic of the Marshall Islands is a country of around 50,000 people spread across more than 1,000 islands in a remote part of the Pacific Ocean. The country relies heavily on cross-border finance and trade, and the complexities of that system can make it difficult for citizens to get certain goods and financial services efficiently. Now the federal government is seeking to become the first to issue a national digital currency using blockchain technology. Officials hope the move helps citizens…

Free Software creates a world of possibilities for low-resource countries in research and development areas

The speed and dynamism in the software industry have led to a rethinking of the knowledge on which traditional software development is based. Recent studies and the same current market is setting the trend in software engineering, having as main characteristics meeting the needs of speed, flexibility and external variants that make our environment a more competitive advantage by increasing productivity and satisfying customer needs. In the shortest possible time to provide greater value to the business. Faced with this situation, the degree of adaptation of traditional methodologies to these work environments were not entirely efficient and did not meet…

With 3D printers, robotics development is now possible from home

To start today we must know that a 3D printer has the ability to make replicas of 3D designs, it is a printer that can create volumetric pieces or models from a design made by a computer. This project arises with the idea of converting 2D files into real 3D prototypes, it must be said that it has been used in the prefabrication of parts, in sectors such as architecture and industrial design. However, it can be noted that nowadays the use of the manufacture of all kinds of objects is spreading, such as: models for casting, very complicated pieces,…
