Intel CPU efficiency Chart.

This data was collected from Wikipedia and the Intel Web site.

If we assume 1 CPU clock tick is of equal value on all Intel Processors then we can work out total speed as the clock speed times the number of cores.

In actually is much more complicated.

Graph above last updated in 2005 and doesn't include data beyond the original P4 processors.

The above chart attempts to work out the amount of processing per clock tick on a single core.

What was interesting is the 1/3 drop in the amount of work done per cycle on the highest end P4 CPU's.

The Chart below is sorted from Worst to best. I included the older 3.8 GHz P4 and P4M for comparison. These are 2 to worst entries at the top of the table.


CPU Model	Clock GHz	# of Cores	TPD Watts	Speed (Clock*Cores)	Efficiency (Ghz / Watt)

Countdown Clock/Timer in /bin/bash

Often there is a need to have time between batch jobs. Knowing how much time there is between jobs is useful.

Here are two version.

One I found on unix.com here by cfajohnson. He claims it will work in any POSIX shell
The other I (tc) wrote.

Version #1

# by cfajohnson
countdown()
(
  IFS=:
  set -- $*
  secs=$(( ${1#0} * 3600 + ${2#0} * 60 + ${3#0} ))
  while [ $secs -gt 0 ]
  do
    sleep 1 &
    printf "\r%02d:%02d:%02d" $((secs/3600)) $(( (secs/60)%60)) $((secs%60))
    secs=$(( $secs - 1 ))
    wait
  done
  echo
)

countdown "00:07:55"

Version #2

# by teacup
countSecondsDown()
{
  seconds=$1
  while [ $seconds -ge 0 ]
  do
    # you need the ampersand after sleep if you use wait.
    # because wait will wait for child process of sleep to complete.
    sleep 1 &
    printf "\r%d  " $seconds
    seconds=$(( $seconds - 1 ))
    wait
  done
  echo

}

countSecondsDown 71

Real-time and fully distributed protocol with no centralized datacenters

http://telehash.org/

JSON+UDP+DHT=Freedom

A new wire protocol enabling applications to connect directly in a real-time and fully distributed manner, freeing them from relying on centralized datacenters

It works by sending and receiving small bits of JSON via UDP using an efficient routing system based on Kademlia, a proven and popular Distributed Hash Table. Everything within TeleHash is routed based on a generic SHA hash of the related id or URL.
