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. -

Why does Wireshark say no interfaces found ? Linux Hint [3] Wireshark is a very famous, open-source network capturing and analyzing tool. While using Wireshark, we may face many common issues. One of the common issues is ?No Interfaces are listed in Wireshark?. Let?s understand the issue and find a solution in Linux OS.If you do not know Wireshark basic, then check Wireshark Basic first, then come back here. How to Solve ?Sub-process /usr/bin/dpkg returned an error code (1)? In Ubuntu[4] It?s not uncommon to run into an issue of broken packages in Ubuntu and other Debian-based distributions. Sometimes, when you upgrade the system or install a software package, you may encounter the ?Sub-process /usr/bin/dpkg returned an error code? error. For example, a while back, I tried to upgrade Ubuntu 18.04 and I bumped into the dpkg error as shown below. [...] This type of dpkg error points to an issue with the package installer usually caused by the interruption of an installation process or a corrupt dpkg database. Any of the above-mentioned solutions should fix this error. -

Coordinates are given as an ordered pair of numbers, with the x-coordinate first. The origin is the lower left, at (0,0). The reference lines are the x and y axes. All grid lines are drawn parallel to the two reference lines. The purpose of the grid is to make it easier to make distance measurements between a location-point and the reference lines. 5 4 3 (2,3) 2 s 1 i x a (-2,0) - 0 y -1 -2 (1,-2) -3 -4 -5 -5 -4 -3 -2 -1 0 1 2 3 4 5 x - axis Figure 2.3 A more general coordinate grid places the origin (0,0) at the center of the grid.

Hydra: a Declarative Approach to Continuous Integration1
Hydra: A Declarative Approach to Continuous Integration1 Eelco Dolstra, Eelco Visser Department of Software Technology, Faculty of Electrical Engineering, Mathematics and Computer Science (EWI), Delft University of Technology, The Netherlands Abstract There are many tools to support continuous integration: the process of automatically and con- tinuously building a project from a version management repository. However, they do not have good support for variability in the build environment: dependencies such as compilers, libraries or testing tools must typically be installed manually on all machines on which automated builds are performed. In this paper we present Hydra, a continuous build tool based on Nix, a package manager that has a purely functional language for describing package build actions and their dependencies. This allows the build environment for projects to be produced automatically and deterministically, and so significantly reduces the effort to maintain a continuous integration en- vironment. 1. Introduction Hydra is a tool for continuous integration testing and software release that uses a purely func- tional language to describe build jobs and their dependencies. Continuous integration (Fowler and Foemmel 2006) is a simple technique to improve the quality of the software development process. An automated system continuously or periodically checks out the source code of a project, builds it, runs tests, and produces reports for the developers. Thus, various errors that might accidentally be committed into the code base are automatically caught. Such a system allows more in-depth testing than what developers could feasibly do manually: • Portability testing: The software may need to be built and tested on many different plat- forms. -

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.

Далі в доповіді будуть розглянуті подробиці інтероперабельності платформ з Linux Server, Apache Hadoop, Java, PHP, Node.JS, MongoDb, і наостанок дізнаємося про цікаві Open Source-розробки Microsoft Research. OpenSource Software in Mac OS X V. Zhhuta UK2 LImIted t/a VPS.NET, [email protected] Max OS X stem from Unix: bSD. It contains a lot of things that are common for Unix systems. Kernel, filesystem and base unix utilities as well as it's own package managers. It's not a secret that Mac OS X has a bSD kernel Darwin. The raw Mac OS X won't provide you with all power of Unix but this could be easily fixed: install package manager. There are 3 package manager: MacPorts, Fink and Homebrew. To dive in OpenSource world of mac os x we would try to install lates version of bash, bash-completion and few other utilities. Where we should start? First of all you need to install on you system dev-tools: Xcode – native development tools that contain GCC and libraries. Next step: bring a GIU – X11 into your system. Starting from Mac OS 10.8 X11 is not included in base-installation and it's need to install Xquartz(http://xquartz.macosforge.org). Now it's time to look closely to package managers MacPorts Site: www.macports.org Latest MacPorts release: 2.1.3 Number of ports: 16740 MacPorts born inside Apple in 2002. -

It is designed to get customers up and running quickly and describes how to compile and run a DPDK application in a FreeBSD application (bsdapp) environment, without going deeply into detail. For a comprehensive guide to installing and using FreeBSD, the following handbook is available from the FreeBSD Documentation Project: FreeBSD Handbook. Note: The DPDK is now available as part of the FreeBSD ports collection. Installing via the ports collection infrastructure is now the recommended way to install the DPDK on FreeBSD, and is documented in the next chapter, Installing DPDK from the Ports Collection.
