ssacli) installation and usage on Proxmox PVE (6.x)You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.
CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.
ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.
DOCS: also refer to https://docs.docker.com/config/pruning/
HINT: add the --force option to the cmdlines to not prompt for confirmation (e.g. for usage inside scripts)

This is a compiled list of falsehoods programmers tend to believe about working with time.
Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).
It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
In spring 2017, GNOME Terminal and iTerm2 have changed this.
GNOME Terminal is based on the VTE widget, and almost all of this work went to VTE. As such, we expect other VTE-based terminal emulators to catch up and add support really soon. Other terminal emulators are also welcome and encouraged to join!
