iPhone 4 awarded Guinness World Records – Poor Apple

Filed under: General — Tags: , , , , — admin @ 7:09 am

After market of smart phones is conquered by an army of Android phones and iOS market share is falling so fast,
I heard the news that iPhone 4 is awarded some Guinness Word Records , it seems a good news for fruit company fans at the first glance, but they should hope no one reads the full story 😀
Lets see what is the Record for : “Fastest-Selling Portable Gaming System” wtf ! and it is compared to PSP and Nintendo.

Guinness states that the iPhone 4’s first-day sales estimates of 1.5 million make it the fastest selling game system in history. By comparison the PSP only sold 200,000 units its first day and the Nintendo DS sold 600,000 units in its first week.

I guess fruit company should sue Guinness for this record because everyone was thinking iPhone is a smartphone and does not fall into the category of portable gaming systems ! lol
and now we may expect some new records for iPhone in near future :
The fastest selling portable internet TV ( cause you can watch youtube on it )
The fastest selling portable WC notification system ( cause it shows the place of public WC’s on the map )
and many more …
After fruit company shot itself in the leg by suing Samsung for some nonsense claims, now we see this desperate attempt to save iPhone.
I am sorry Steve, let me tell you what you should do to save iPhone market.
You should create an iPhone with Android OS on it , If I remember correctly it is what you have already done for your desktops and laptops after your share of desktop and laptop market dropped to nothing. right ?
you let users buy your products and install windows on it. that was a wise decision 🙂
Why don’t you learn a lesson from history ?

How to check domain NS glue records using dig

Filed under: dns — Tags: , , , , , — admin @ 11:52 am

Lets check microsoft.com NS glue records by dig command.

As it is a .com domain first we should check root servers for .com by the following command :

dig NS com

Result :

com.                    22124   IN      NS      d.gtld-servers.net.
com.                    22124   IN      NS      f.gtld-servers.net.
com.                    22124   IN      NS      a.gtld-servers.net.
com.                    22124   IN      NS      c.gtld-servers.net.
com.                    22124   IN      NS      g.gtld-servers.net.
com.                    22124   IN      NS      i.gtld-servers.net.
com.                    22124   IN      NS      l.gtld-servers.net.
com.                    22124   IN      NS      m.gtld-servers.net.
com.                    22124   IN      NS      k.gtld-servers.net.
com.                    22124   IN      NS      e.gtld-servers.net.
com.                    22124   IN      NS      h.gtld-servers.net.
com.                    22124   IN      NS      b.gtld-servers.net.
com.                    22124   IN      NS      j.gtld-servers.net.

We can choose any root server for next query , I will choose m.gtld-servers.net :

dig NS microsoft.com @m.gtld-servers.net

Result :

;; AUTHORITY SECTION:
microsoft.com.          172800  IN      NS      ns1.msft.net.
microsoft.com.          172800  IN      NS      ns2.msft.net.
microsoft.com.          172800  IN      NS      ns3.msft.net.
microsoft.com.          172800  IN      NS      ns4.msft.net.
microsoft.com.          172800  IN      NS      ns5.msft.net.

;; ADDITIONAL SECTION:
ns1.msft.net.           172800  IN      A       65.55.37.62
ns2.msft.net.           172800  IN      A       64.4.59.173
ns3.msft.net.           172800  IN      A       213.199.161.77
ns4.msft.net.           172800  IN      A       207.46.75.254
ns5.msft.net.           172800  IN      A       65.55.226.140

OK we are done , the ADDITIONAL SECTION in last query contains the glue records :

ns1.msft.net.           172800  IN      A       65.55.37.62
ns2.msft.net.           172800  IN      A       64.4.59.173
ns3.msft.net.           172800  IN      A       213.199.161.77
ns4.msft.net.           172800  IN      A       207.46.75.254
ns5.msft.net.           172800  IN      A       65.55.226.140
