I Am Not Clueless Myths and Misconceptions About the Design Of
I am not clueless or Myths and misconceptions about the design of GoboLinux Hisham H. Muhammad April 11, 2017 “Those who do not understand Unix are doomed to reinvent it, poorly.” – Henry Spencer, 1987 This week we had another release of GoboLinux, and again a number of people, even if indirectly, called me “clueless” for coming up with such a structure for a Linux distribution, for a number of reasons. None of those reasons was new; I heard all of them many times. This article is an attempt to sum them up, and explain why I chose the design decisions I made, hopefully clearing any pending misconceptions. I don’t have illusion this will prevent them keep happening, but at least I’ll have a text to point people to. This article ranges from common misconceptions from those who have never used GoboLinux, to well-intentioned but poorly-thought-out ideas that keep coming from time to time to the GoboLinux mailing list, often causing long debates. I’ll be separating the points in sections and they are meant to be self-contained, so feel free to skip directly to the ones that interest you, if you don’t feel like reading the whole thing. “There is a reason why things are the way they are” This is something I hear constantly, often followed by an explanation about the difference between /, /usr and /usr/local, and/or /bin and /sbin. I do understand the difference1. If I did away with this three-level distinction, is because I believe there are other ways to approach the problems this distinction tries to solve. -

This acquisition was not community has different attitudes towards GitHub is the idea without controversy, as it is well-known that the free software communities includes not only the ability to use software freely, of ‘forking’ so far, as it it is considered as a danger to FLOSS but also the libre nature in Open Source Software. In this study, development [10]. our aim is to explore these perceptions in FLOSS developers. We In this paper, we report on how external events such as conducted a survey that covered traditional FLOSS source Linux, acquisition of the open source platform by a closed source and BSD communities and received 246 developer responses. organization triggers a FLOSS developers such the Linux/ The results of the survey confirm that the free community did trigger some communities to move away from GitHub and raised BSD Free Software communities. discussions into free and open software on the GitHub platform. The study reminds us that although GitHub is influential and II. TARGET SUBJECTS AND SURVEY DESIGN trendy, it does not representative all FLOSS communities. -

It also provides helpful tools to constrain or pin versions in recipes. Building a conda package requires installing conda-build and creating a conda recipe. You then use the conda build command to build the conda package from the conda recipe. You can build conda packages from a variety of source code projects, most notably Python. For help packing a Python project, see the Setuptools documentation. OPTIONAL: If you are planning to upload your packages to Anaconda Cloud, you will need an Anaconda Cloud account and client.

Luarocks Past, Present and Future
LuaRocks past, present and future Hisham Muhammad Prologue: what is LuaRocks? ● A package manager for Lua modules ● Modules written in Lua (.lua), binary Lua modules (.so/.dll) and Lua scripts ● Usual features you would expect from a package manager ○ luarocks install <module> ○ luarocks remove <module> ○ ... Rocks and rockspecs ● Rock: a LuaRocks package ○ archive files (actually .zip files) ○ *.src.rock - contains source code ○ *.win32-x86.rock - “binary rock”, contains compiled binaries for a given platform ● Rockspec: a package specification file ○ A declarative Lua script, with rules on how to build and package rocks ○ *.rockspec - a Lua file containing some tables A rockspec Part I The past: a short history of LuaRocks Origins ● Kepler Project: research project to develop a platform for web development using Lua ○ combining modules that already existed (LuaSocket, CGILua) and adding the missing pieces ○ For more of the story, read Yuri Takhteyev’s book, “Coding Places” :) ● I started (re)writing Unix makefiles to automate the packaging/install process ● Common patterns emerged LuaRocks 0.x-1.x: a bumpy start ● 0.x was a gradual evolution ○ the goal for 1.0 was for it to be able to build all Kepler modules ● The rockspec format is unchanged since 1.0 ○ We really care about compatibility ○ Learning the format and writing a rockspec are not disposable efforts ● We got many things right, but we also got some of them wrong... Annoyances in LuaRocks 1.x ● LuaRocks 1.0 did not use the standard Lua layout for modules ○ It wasn’t clear that -
