As usual I was compiling the linux kernel on my Intel Quad Core desktop, and power goes off.. The UPS starts beeping to indicate that it is low on battery. Well, I decided to stop the compilation and poweroff the machine. To my surprise, the beeping went away! I was confused. I started the compile again, and lo, the UPS sang again..
The power consumption increases so much that the UPS detects it as a higher rate of battery discharge and starts beeping! I was amazed!
Probably when we have much bigger machines , I can expect the light bulbs in my room to dim down when I begin a kernel compilation. :-)
