  • Kill -9 is a command on Unix and Linux to send signal 9 (SIGKILL) to a process. That’s the version of kill that is the most reliable and has immediate effect.

    Taskkill is a Windows command line program. I believe that taskkill /f uses the TerminateProcess() API. This is more forceful than the End Task button on the Task Manager. There is a different End Process button on the Task Manager that does use TerminateProcess().






  • The Linux software you can get as a regular user from your typical Linux distributions is absolutely not any more secure on average than your typical Windows software.

    I say this as someone who writes application programs on both systems.

    I think it’s really debatable whether the Linux kernel is really any more secure than the Windows NT kernel. Linux advocates have pushed the “many eyes, shallow bugs” line for a long time, but high profile lapses seem to really have put the lie to that.




  • Let us all remember that, at least back when it started, the establishment alternative to systemd was a product named after its original operating system, System V UNIX, which is a direct descendent of the original UNIX from AT&T. This sysvinit software used complicated shell scripts to manage daemons. Contrary to some opinions, these shell scripts were not “just working”; they were in fact a constant and major maintenance burden for Linux distributions. When I started on Linux at least, Debian had a suspiciously large fraction of bugs on init script breakages.

    All this is to say that the new system, systemd, doesn’t have to be anywhere near perfect to be worth replacing sysvinit.

    People argue that systemd is rejecting the “UNIX philosophy” of small tools that do one thing well. I argue that this UNIX philosophy is not some kind of universal good with no tradeoffs. It’s an engineering rule of thumb. There are always tradeoffs.

    People argue that systemd is too much like Windows NT. I argue that Windows NT has at least a few good ideas in it. And if one of those ideas solves a problem that Linux has, Linux should use that idea.
