Now For The Daily Tasks." https://nxdomain.no/~peter/openbsd_installed_now_for_the_daily_tasks.html which should help answer some common questions. #openbsd #newrelease #maintenance #sysadmin #security #dailytasks #freesoftware #libresoftware

Super happy!

In today’s episode of "You can’t pronounce the hostname but you can hopefully read the content", an overview of the two #ThinkCentre that I recently got, centered towards power consumption when running #FreeBSD, #NetBSD and #OpenBSD.
