  • Article, Written by Wobo in Early October 2010, Published in Print in Linux User, Issue # 11/2010 (In German)
    Article, written by wobo in early October 2010, published in print in Linux User, issue # 11/2010 (in German) (translated to English for Mageia by wobo) Introduction Numerous economical problems in the French company Mandriva SA have finally been answered by the community: former employees and free developpers have decided to build a plattform to continue the development of the distribution as a free and open community project. Article The 19th September marked a turning point in the history of the Distribution currently known as Mandriva Linux: Several former employees of Mandriva SA announced the intention to found a nonprofit organization that wishes to continue the distribution Mandriva Linux in a fork as a community project [1 ]. The reasons for this step go back to the year 2005: at that time the newcomer Ubuntu appeared on the scene simultaneously with the restructuring of the ailing Mandriva SA (see box of MandrakeSoft to Mandriva on the next spread). While this newcomer gained more and more popularity Mandriva failed to start a positive trend in its business and critical voices in the community arose about the Mandriva management. Mandriva©s business and communication policy met a rising reluctance of users and free developers. A key moment in this crisis was certainly the lay-off of company co-founder Gael Duval, along with popular community leaders (like Adam Williamson) and well known freelancers [2]. Downward trend Despite numerous cuts in various business areas the decline of Mandriva SA continued unabated. In spring 2010 the company was on the brink of bankruptcy and started initial negotiations with interested buyers.

To synergize such developments the CEPC [1], CLIC [2], 15 FCC [3], ILC [4], and SCT [5], communities have started the creation of a “Turnkey Software Stack” 16 (Key4hep), which would provide all the necessary ingredients, from simulation to analysis, for future 17 experiments. This approach is based on the positive experience of the linear collider projects ILC 18 and CLIC, that have developed and used a common software stack iLCSoft [6] over the last decade. 19 This would cover most if not all future linear and circular machines colliding electrons, muons and 20 hadrons. The software stack will facilitate writing specific components for experiments ensuring co- 21 herency and maximising the re-use of established packages to benefit from existing solutions and 22 community developments, for example, ROOT, Geant4, DD4hep, Gaudi and podio.

  • Getting Started with LINUX a Personal Experience
    Getting Started with LINUX a personal experience IWPCUG March 7th 2018 Mike Hoar Have been on the fringes of Linux for some years (I pronounce it the Scandinavian way Lee-nux a combination of Linnus Thorvald and UNIX). This presentation provides an introduction to Linux in the form of a record of my investigations and experience of installing, configuring and initial use of a Linux setup. 1 Part 1: The Background • What is Linux? • What do I want to use it for? • What hardware do I have? 2 What is LINUX? An Operating System Just like Windows, iOS and UNIX Computers need an OS, software and peripheral hardware to perform. The OS enables the software to run and communicate with the printers, monitors and other media devices. Just like Windows XP, Windows 7, Windows 8, and Mac OS X, Linux is an operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply – the operating system manages the communication between your software and your hardware. Without the operating system (often referred to as the “OS”), the software wont function. Operating systems have been around since general purpose computers were first developed. They have just got more sophisticated and complex. The first home computers such as the Commadore64 and Sinclair ZX machines had the OS hard wired into the machine. When the IBM PC was developed it came with the first OS which was installed every time you started up the machine, this was Microsofts DOS. Other versions were soon developed which were compatible with software written to run on MS-DOS .
