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. -

Schon Mal Dran Gedacht,Linux Auszuprobieren? Von G. Schmidt
Schon mal dran gedacht, Linux auszuprobieren? Eine Einführung in das Betriebssystem Linux und seine Distributionen von Günther Schmidt-Falck Das Magazin AUSWEGE wird nun schon seit 2010 mit Hilfe des Computer-Betriebs- system Linux erstellt: Texte layouten, Grafiken und Fotos bearbeiten, Webseiten ge- stalten, Audio schneiden - alles mit freier, unabhängiger Software einer weltweiten Entwicklergemeinde. Aufgrund der guten eigenen Erfahrungen möchte der folgende Aufsatz ins Betriebssystem Linux einführen - mit einem Schwerpunkt auf der Distri- bution LinuxMint.

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.

Linux at 25 PETERHISTORY H
Linux at 25 PETERHISTORY H. SALUS Peter H. Salus is the author of A n June 1991, at the USENIX conference in Nashville, BSD NET-2 was Quarter Century of UNIX (1994), announced. Two months later, on August 25, Linus Torvalds announced Casting the Net (1995), and The his new operating system on comp.os.minix. Today, Android, Google’s Daemon, the Gnu and the Penguin I (2008). [email protected] version of Linux, is used on over two billion smartphones and other appli- ances. In this article, I provide some history about the early years of Linux. Linus was born into the Swedish minority of Finland (about 5% of the five million Finns). He was a “math guy” throughout his schooling. Early on, he “inherited” a Commodore VIC- 20 (released in June 1980) from his grandfather; in 1987 he spent his savings on a Sinclair QL (released in January 1984, the “Quantum Leap,” with a Motorola 68008 running at 7.5 MHz and 128 kB of RAM, was intended for small businesses and the serious hobbyist). It ran Q-DOS, and it was what got Linus involved: One of the things I hated about the QL was that it had a read-only operating system. You couldn’t change things ... I bought a new assembler ... and an editor.... Both ... worked fine, but they were on the microdrives and couldn’t be put on the EEPROM. So I wrote my own editor and assembler and used them for all my programming. Both were written in assembly language, which is incredibly stupid by today’s standards. -
Linux Versions
Linux Versions The Linux "product" is provided in a large number of different versions, known as "distributions," each of which retains the core kernel and GNU tools. Additionally, a variety of common tools (such as KDE, Apache, and Samba) are backed with a collection of additions and service options that meet a particular market niche. Red Hat holds the largest Linux installed base in the US, Novell SUSE Linux in Europe, and TurboLinux (based in Japan) in Asia-Pacific. Mainstream distributions--i.e. commercial applications fully supported by their vendor—have typical license and maintenance fees, just as any other commercial software applications would, while community supported distributions tend to be free to users. Table below lists the best-known Linux distributors, as well as companies that support multiple versions of Linux versions developed by others.

System Calls Instrumentation for Intrusion Detection In
System Calls Instrumentation for Intrusion Detection in Embedded Mixed-Criticality Systems Marine Kadar SYSGO GmbH, Klein-Winternheim, Germany [email protected] Sergey Tverdyshev SYSGO GmbH, Klein-Winternheim, Germany [email protected] Gerhard Fohler Technische Universität Kaiserslautern, Germany [email protected] Abstract System call relative information such as occurrences, type, parameters, and return values are well established metrics to reveal intrusions in a system software. Many Host Intrusion Detection Systems (HIDS) from research and industry analyze these data for continuous system monitoring at runtime. Despite a significant false alarm rate, this type of defense offers high detection precision for both known and zero-day attacks. Recent research focuses on HIDS deployment for desktop computers. Yet, the integration of such run-time monitoring solution in mixed-criticality embedded systems has not been discussed. Because of the cohabitation of potentially vulnerable non-critical software with critical software, securing mixed-criticality systems is a non trivial but essential issue. Thus, we propose a methodology to evaluate the impact of deploying system call instrumentation in such context. We analyze the impact in a concrete use-case with PikeOS real-time hypervisor. 2012 ACM Subject Classification Security and privacy → Embedded systems security; Security and privacy → Intrusion detection systems Keywords and phrases Instrumentation, Mixed-criticality, Real-Time, System Calls, Host Intrusion Detection Systems Digital Object Identifier 10.4230/OASIcs.CERTS.2019.2 Funding This work has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 764785, FORA—Fog Computing for Robotics and Industrial Automation. -
