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. ...

Sus inicios coincidieron con el Sistema 360 de IBM, máquinas que andaban por las universidades en los 70 curiosamente «un tanto desocupados» porque la gente no sabía muy bien qué hacer con ellos. Pike aprendió allí a programar. Luego tuvo acceso a un PDP-11 en la universidad de Toronto y a otras máquinas. Cuando llegó a los los laboratorios Bell se encontró con el Unix recién nacido y trabajó con Ken Thompson y con Kernighan y Ritchie, creadores del lenguaje C. ...

The evolution of the Unix operating system is made available as a version-control repository, covering the period from its inception in 1972 as a five thousand line kernel, to 2015 as a widely-used 26 million line system. The repository contains 659 thousand commits and 2306 merges. The repository employs the commonly used Git system for its storage, and is hosted on the popular GitHub archive. It has been created by synthesizing with custom software 24 snapshots of systems developed at Bell Labs, Berkeley University, and the 386BSD team, two legacy repositories, and the modern repository of the open source FreeBSD system. In total, 850 individual contributors are identified, the early ones through primary research. The data set can be used for empirical research in software engineering, information systems, and software archaeology. ...

The program Bentley asked Knuth to write is one that’s become familiar to people who use languages with serious text-handling capabilities: Read a file of text, determine the n most frequently used words, and print out a sorted list of those words along with their frequencies. » Dr. Drang | leancrew.com

There is a community, a shared culture, of expert programmers and networking wizards that traces its history back through decades to the first time-sharing minicomputers and the earliest ARPAnet experiments. The members of this culture originated the term ’hacker’. Hackers built the Internet. Hackers made the Unix operating system what it is today. Hackers make the World Wide Web work. If you are part of this culture, if you have contributed to it and other people in it know who you are and call you a hacker, you’re a hacker. ...
