We present a tutorial on numerical computation for undergrads in Sciences, Maths and Engineering, based on Octave, a popular framework for numerical analysis which, in addition, is FOSS (Free & Open Source Software). So it can be freely run on several operating systems: Windows, MacOS, any GNU-Linux flavour, FreeBSD and, even, on Android mobile platform. The tutorial is given as a static web page with almost no extra complexities, such as database engine, dynamic rendering via PHP or similar. All the workflow is arranged through FOSS with full respect to standards. Keywords: FOSS; octave; webpage; tutorial; markup language; markdown

The Stability

In the present work, by using a paralelepipedic thermogravitational microcolumn, the temperature gradient influence on the stability of the flow was or has been examined, emphasizing mixtures with negative Soret coefficients. Experiments and numerical analysis were conducted for DCMIX2 Toulene-Methanol binary subsystem. This binary subsystem has a broad range of negative Soret values for low concentrations of Methanol which was analysed. Two different concentrations have been studied in order to confirm existence of temporal stability windows of those mixtures. Experiments were compared with numerical simulations conducted in open source software OpenFOAM, for both cases.

Hacking, as a mode of technical and cultural production, is commonly celebrated for its extraordinary freedoms of creation and circulation. Yet surprisingly few women participate in it: rates of involvement by technologically skilled women are drastically lower in hacking communities than in industry and academia. This book investigates the activists engaged in free and open-source software to understand why, despite their efforts, they fail to achieve the diversity that their ideals support. The book shows that within this well-meaning volunteer world, beyond the sway of human resource departments and equal opportunity legislation, members of underrepresented groups face unique challenges. The book explores who participates in voluntaristic technology cultures, to what ends, and with what consequences. Digging deep into the fundamental assumptions underpinning STEM-oriented societies, the book demonstrates that while the preferred solutions of tech enthusiasts—their “hacks” of projects and cultures—can ameliorate some of the “bugs” within their own communities, these methods come up short for issues of unequal social and economic power. Distributing “diversity” in technical production is not equal to generating justice. The book reframes questions of diversity advocacy to consider what interventions might appropriately broaden inclusion and participation in the hacking world and beyond.
