GRUB (Grand Unified Bootloader) es un gestor de arranque disponible del proyecto GNU. Un gestor de arranque es muy importante ya que es imposible iniciar un sistema operativo sin él. Es el primer programa que se inicia cuando se enciende el ordenador. El cargador de arranque transfiere el control al núcleo del sistema operativo. GRUB es el gestor de arranque predeterminado para casi todas las distribuciones de GNU/Linux. Esto se debe a que es mejor que muchas de las versiones anteriores de los cargadores de arranque. Pero ¿Hay vida más allá de GRUB? ...

This is mainstream opinion. Linux is better than anything else and money is poured in constantly, more than in other platforms. And aside this is not true, this is not based in facts but on feelings. Most GNU/Linux distributions are very average on many aspects. The fact they run on many servers on this planet and many developers work on them, doesn’t make them better than ‘X’. They are popular but that’s it. ...

Since the 1970’s, Vi and its successor Vim have been included by default on many operating systems, including almost all GNU/Linux distributions. Vim is free and open-source and is one of the most popular code editors. It can be downloaded on Vim official site. » Jean-Baptiste Jung | catswhocode.com

The vast majority of PC users today have no memory of what PC keyboards looked like before the standard 101/102-key layout arrived, even though various OEMs do their best to mangle the standard layout in order to minimize usability, especially on laptops. OEM-specific modifications aside, the basic layout of the main block of alphanumeric keys has not changed in over 30 years, since 1986. However, up until that point the PC keyboard layout and the keyboard hardware changed quite a bit, and looking at the 1981-1986 IBM Technical References is key to understanding a) why the standard keyboard scan codes are so complex, and b) why there are so many seemingly odd vendor-specific modifications of the standard layout. ...

The Object-Oriented Design Principles are the core of OOP programming, but I have seen most of the Java programmers chasing design patterns like Singleton pattern, Decorator pattern, or Observer pattern, and not putting enough attention on learning Object-oriented analysis and design. It’s important to learn the basics of Object-oriented programming like Abstraction, Encapsulation, Polymorphism and Inheritance. But, at the same time, it’s equally important to know object-oriented design principles. » Hacker Noon | hackernoon.com

A ojos de alguien no-experto en matemáticas, el arco que encabeza estas líneas puede transmitir una gran armonía, pero resultaría difícil explicar el por qué. La causa de esa armonía está en las matemáticas empleadas para su diseño, para una composición extraordinariamente calculada. Este arco en concreto es el arco del mihrab islámico cordobés del granadino palacio de la Madraza, un lugar que indica hacia qué dirección se debe rezar según la religión musulmana. Si nos fijamos, los arcos interior y exterior no son concéntricos, es decir, no comparten el mismo eje. El arco interior está elevado R/2 por encima del eje de impostas, y el arco exterior elevado un R/5. ...

Software development is an amazing job that can sometimes feel like juggling chainsaws. Between maintaining your current code base and releasing new features and projects, it is fairly easy to think of security as Someone Else’s Problem –you have enough to deal with. But there is a major benefit to incorporating security consciousness into your workflow. » DEV Community | dev.to
