The guys behind AlgoRythmics found a brilliant way of showing how the sorting algorithms work: they used popular Romanian and Hungarian dance!
Have a look below how the bubble sort was done:

For more dancing watch their YouTube page: they also ‘implemented’ quick sort, insert sort, merge sort and shell sort. You can also play with their sorting tools on their website until you are sure you understood how these sorting algorithms work.
PS – hear and see also the sound of 15 sorting algorithms

A simple trick about nslookup that I learned while reading the Smashing Magazine’s free preview of their Book #4

To start, the full syntax of nslookup is:
nslookup [-option] [hostname] [server]

When you run nslookup [hostname], it’s your local DNS server that answers the query. This answer is non-authoritative.
With an additional step, you can get the local name servers of the hostname: nslookup -type=ns [hostname]
Using one of these local DNS servers, you can query again: nslookup [hostname] [local_name_server]. This answer is authoritative.

$ nslookup www.smashingmagazine.com
Server: 194.168.4.100
Address: 194.168.4.100#53
Non-authoritative answer:
Name: www.smashingmagazine.com
Address: 80.72.139.101

$ nslookup -type=ns www.smashingmagazine.com
Server: 194.168.4.100
Address: 194.168.4.100#53
Authoritative answers can be found from:
smashingmagazine.com
origin = a.regfish-ns.net
mail addr = postmaster.regfish.com...

$ nslookup www.smashingmagazine.com a.regfish-ns.net
Server: a.regfish-ns.net
Address: 79.140.49.11#53
Name: www.smashingmagazine.com
Address: 80.72.139.101

To clean the DNS cache, use ipconfig /flushdns.
