Github: a Case Study of Linux/BSD Perceptions from Microsoft's

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. -

In short, we cut to the most efficient ways of using BSD systems. Our goal with BSD UNIX Toolbox is to pack a lot of useful information for using BSD systems into a small package that you can carry around with you. To that end, we describe: ❑ Commands — Tons of command line examples to use BSD systems in helpful and clever ways ❑ GUI Tools — Quick pointers to graphical administration tools to configure your system ❑ Software packages — Short procedures to find and download tons of applications ❑ OnlineCOPYRIGHTED resources — Listings of the best MATERIAL locations to find BSD forums, mailing lists, IRC channels, and other online resources ❑ Local documentation — Tools for gathering more information from man pages, doc directories, help commands, and other resources on your BSD system Because you’re not a beginner with BSD systems, you won’t see a lot of screenshots of windows, icons, and menus. -
BSD Based Systems
Pregled BSD sistema I projekata Glavne BSD grane FreeBSD Homepage: http://www.freebsd.org/ FreeBSD je Unix-like slobodni operativni sistem koji vodi poreklo iz AT&T UNIX-a preko Berkeley Software Distribution (BSD) grane kroz 386BSD i 4.4BSD. Radi na procesorima kompatibilnim sa Intel x86 familijom procesora, kao I na DEC Alpha, UltraSPARC procesorima od Sun Microsystems, Itanium (IA-64), AMD64 i PowerPC procesorima. Radi I na PC-98 arhitekturi. Podrska za ARM i MIPS arhitekture je trenutno u razvoju. Početkom 1993. godine Jordan K. Hubbard, Rod Grimes i Nate Williams su pokrenuli projekat čiji je cilj bio rešavanje problema koji su postojali u principima razvoja Jolitzovog 386BSD-a. Posle konsultovanja sa tadašnjim korisnicima sistema, uspostavljeni su principi i smišljeno je ime - FreeBSD. Pre nego što je konkretan razvoj i počeo, Jordan Hubbard je predložio je firmi Walnut Creek CDROM (danas BSDi) da pripreme distribuiranje FreeBSD-a na CD-ROM-ovima. Walnut Creek CDROM su prihvatili ideju, ali i obezbedili (tada potpuno nepoznatom) projektu mašinu na kojoj će biti razvijan i brzu Internet konekciju. Bez ove pomoći teško da bi FreeBSD bio razvijen u ovolikoj meri i ovolikom brzinom kao što jeste. Prva distribucija FreeBSD-a na CD-ROM-ovima (i naravno na netu) bila je FreeBSD 1.0, objavljena u decembru 1993. godine. Bila je zasnovana na Berkeley-evoj 4.3BSD-Lite ("Net/2") traci, a naravno sadržala je i komponente 386BSD-a i mnoge programe Free Software Foundation (fondacija besplatnog- slobodnog softvera). Nakon što je Novell otkupio UNIX od AT&T-a, Berkeley je morao da prizna da Net/2 traka sadrži velike delove UNIX koda. -
