Hack and / - Lightning Hacks—the Command Next Door
The problem with powerful server hardware is that it always takes a little time to reboot. Often when I have to reboot a server, I want to know the moment it comes back up, because I want to log back in and finish some work. Usually when I reboot a machine, I start a ping process, so I can watch to see when it is available. The problem is that servers seem to take just long enough to come back up that I end up getting distracted in another window on my desktop and don't see the ping replies. My solution to this is to make ping audible:
$ ping -a 10.0.1.7
When you pass the -a command to ping, it generates an audible bell for every ping reply. I get to hear a few system beeps as the server goes down, and then I hear only silence. If I do become distracted and the server comes back, I immediately start hearing this annoying system beep in my ear and know the server is ready.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
