Github: a Case Study of Linux/BSD Perceptions from Microsoft's
1 FLOSS != GitHub: A Case Study of Linux/BSD Perceptions from Microsoft’s Acquisition of GitHub Raula Gaikovina Kula∗, Hideki Hata∗, Kenichi Matsumoto∗ ∗Nara Institute of Science and Technology, Japan {raula-k, hata, matumoto}@is.naist.jp Abstract—In 2018, the software industry giants Microsoft made has had its share of disagreements with Microsoft [6], [7], a move into the Open Source world by completing the acquisition [8], [9], the only reported negative opinion of free software of mega Open Source platform, GitHub. 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. -
Systemd – Easy As 1, 2, 3
Systemd – Easy as 1, 2, 3 Ben Breard, RHCA Solutions Architect, Red Hat [email protected] Agenda ● Systemd functionality ● Coming to terms ● Learning the basics ● More advanced topics ● Learning the journal ● Available resources 2 Systemd is more than a SysVinit replacement 3 Systemd is a system and service manager 4 Systemd Overview ● Controls “units” rather than just daemons ● Handles dependency between units. ● Tracks processes with service information ● Services are owned by a cgroup. ● Simple to configure “SLAs” based on CPU, Memory, and IO. ● Properly kill daemons ● Minimal boot times ● Debuggability – no early boot messages are lost ● Easy to learn and backwards compatible. 5 Closer look at Units 6 Systemd - Units ● Naming convention is: name.type ● httpd.service, sshd.socket, or dev-hugepages.mount ● Service – Describe a daemon's type, execution, environment, and how it's monitored. ● Socket – Endpoint for interprocess communication. File, network, or Unix sockets. ● Target – Logical grouping of units. Replacement for runlevels. ● Device – Automatically created by the kernel. Can be provided to services as dependents. ● Mounts, automounts, swap – Monitor the mounting/unmounting of file systems. 7 Systemd – Units Continued ● Snapshots – save the state of units – useful for testing ● Timers – Timer-based activation ● Paths – Uses inotify to monitor a path ● Slices – For resource management. ● system.slice – services started by systemd ● user.slice – user processes ● machine.slice – VMs or containers registered with systemd 8 Systemd – Dependency Resolution ● Example: ● Wait for block device ● Check file system for device ● Mount file system ● nfs-lock.service: ● Requires=rpcbind.service network.target ● After=network.target named.service rpcbind.service ● Before=remote-fs-pre.target 9 That's all great .......but 10 Replace Init scripts!? Are you crazy?! 11 We're not crazy, I promise ● SysVinit had a good run, but leaves a lot to be desired. -
