About the availability and efficiency...
|
| |
Hello,
I have corrected an error in my page about the availability and
efficiency, the utilization is equal to the arrival rate divided by
the servive rate, not the inverse..
And here is the part that i have corrected:
As you have noticed, i have finally arrived to the following
mathematical model of our Jackson network that model an Enterprise... more »

Hello,
I have released a new version of Seed7: seed7_05_20120603.tgz
In the Seed7 programming language new statements and operators
can be declared easily. Types are first class objects and therefore
templates/generics need no special syntax. Object orientation is
used when it brings advantages and not in places when other... more »

time
|

Can someone help me understand why a computer's clock is so inaccurate?
And, what are the best ways to cope with this when you need good timing?
Is there maybe a USB stick or something that can offer better timing?

Marzullo's Algorithm
|
| |
Let's say I have one computer that is synchronized to an atomic clock.
Then I have, say 5 other computers, that need the correct time and will attempt to get it by talking to the timekeeper computer. Those 5 computers are all connected to the timekeeper by Wifi, so there can be a bit of latency (although the latency tends to vary).... more »
