Steve Jobs Died 'Peacefully,' Family Says

2011-10-05T23:13:00.000-07:00

The family of former Apple chief executive Steve Jobs said that he died "peacefully" on Wednesday, surrounded by his family. A memorial Web site will be posted.

Jobs passed away at the age of 56. Jobs is survived by his wife Laurene and two children, as well as a daughter from a previous relationship.

On August 24, Jobs stepped down, stating that he could no longer meet his duties and expectations as Apple's chief executive. Jobs was diagnosed with and treated for a rare type of pancreatic cancer in 2004, but he said the 2009 absence was not a resurgence of that cancer. He took a medical leave of absence in January.

In a statement, Jobs' family said he died peacefully.

"Steve died peacefully today surrounded by his family.

"In his public life, Steve was known as a visionary; in his private life, he cherished his family. We are thankful to the many people who have shared their wishes and prayers during the last year of Steve's illness; a website will be provided for those who wish to offer tributes and memories.

"We are grateful for the support and kindness of those who share our feelings for Steve. We know many of you will mourn with us, and we ask that you respect our privacy during our time of grief."

Numerous members of the tech world chimed in with their own tributes, and Twitter was filled with condolences attached to the #RIPSteveJobs hashtag. Online, mourners began leaving notes on Facebook tribute pages as well as the Steve Jobs Day Facebook page.

Apple's board also released its own statement.

"We are deeply saddened to announce that Steve Jobs passed away today," the board said.
"Steve's brilliance, passion and energy were the source of countless innovations that enrich and improve all of our lives. The world is immeasurably better because of Steve.
"His greatest love was for his wife, Laurene, and his family. Our hearts go out to them and to all who were touched by his extraordinary gifts.
John Lasseter, chief creative officer and Ed Catmull, president of Walt Disney and Pixar Animation Studios, released their own joint statement. Jobs was chief executive at Pixar, the digital anaimation house that gave the world Cars, The Incredibles and Toy Story, before it was acquired by Disney in 2006.
"Steve Jobs was an extraordinary visionary, our very dear friend and the guiding light of the Pixar family," Lasseter and Catmull said. "He saw the potential of what Pixar could be before the rest of us, and beyond what anyone ever imagined. Steve took a chance on us and believed in our crazy dream of making computer animated films; the one thing he always said was to simply 'make it great.' He is why Pixar turned out the way we did and his strength, integrity and love of life has made us all better people. He will forever be a part of Pixar's DNA. Our hearts go out to his wife Laurene and their children during this incredibly difficult time."

Kill multiple processes using awk command

2011-07-13T00:05:00.000-07:00

If you wish to kill multiple instances manually executed in background or the running processes of crontab then you can kill them all without taking the headache of selecting process id of each process and giving command "kill -9 process id", so this command can do magic for you

ps -ef | grep "username or process name" | grep -v grep | awk '{ print $2 }' | xargs kill -9

This command will first check running process with specific username or process name than "grep -v grep" will exclude the row which contain the word grep in it after that awk command prints the second column of process id's and "xargs kill -9" will kill all the returned process id's associated with it.

Unix Command Symbols

2010-10-15T11:56:00.000-07:00

> Sign
The symbol > is used to redirect the output of a command.
#cat >list1
cat command read standard input(keyboard) and > redirect the output, which normally goes to screen but in this case is moved into a file called list1

>> Sign

#cat >>list1
>> (symbol) will add more items to the existing file list1

Merging two files
If we have two files list1 and list2 and merging these files in one file.
#cat list1 list2 > biglist
#cat biglist (to read contents of file and verify changes)

(pipe sign)
We use sign to concatenate more than than one commands together.

#crontab -l grep hello.sh

Sed Command VS Head Tail

2010-02-28T07:19:00.000-08:00

Well for past few months i was using the head and tail command to look into desired line inside a file... which works like this

If i want to see line number 45 from filename.txt than,

$head -45 filename.txt | tail -1

which is bit complex, but we can also use sed command(stream editor) for it, which goes like this,

$sed -45 filename.txt

Multiple Area OSPF and Virtual Link

2009-08-21T02:23:00.000-07:00

This lab is about multiple area ospf and creating a virtual link to start communication between area 0 and area 2. Here we have three routers A,B and C connected via serial port and each router connecting their segments. Each router has it own loop back interface, now we will start our configurations. Make sure to configure loop back first than configure OSPF, with this OSPF will become router id.

OSPF Configurations
===================
(A Configurations)
A(config)#int loopback 0
A(config-if)#ip add 11.1.1.1 255.255.255.255
!
A(config)#int s1/0
A(config-if)#ip add 1.1.1.1 255.0.0.0
A(config)#no shut
!
A(config)#int fa0/0
A(config-if)#ip add 200.100.50.50 255.255.255.0
A(config-if)#no shut
!
A(config)#Router ospf 1
A(config-router)#network 11.1.1.1 0.0.0.0 area 2
A(config-router)#network 1.0.0.0 0.255.255.255 area 2
A(config-router)#network 200.100.50.0 0.0.0.255 area 2
!
A#sh ip route
A#sh ip ospf
A#sh ip protocols

(B configurations)
Configure interfaces and now comes OSPF part as below
!
B(config)#Router ospf 1
B(config-router)#network 11.1.1.1 0.0.0.0 area 1
B(config-router)#network 1.0.0.0 0.255.255.255 area 2
B(config-router)#network 2.0.0.0 0.255.255.255 area 1
B(config-router)#network 200.100.100.0 0.0.0.255 area 1

B#sh ip route
B#sh ip ospf
B#sh ip protocols

(C configurations)
Configure interfaces and now comes OSPF part as below
!
C(config)#Router ospf 1
C(config-router)#network 33.3.3.3 0.0.0.0 area 0
C(config-router)#network 2.0.0.0 0.255.255.255 area 1
C(config-router)#network 200.100.150.0 0.0.0.255 area 0

C#sh ip route
C#sh ip ospf
C#sh ip protocols
!
Now CREATING A VIRTUAL LINK TO EXTEND THE BACKBONE AREA 0 TO COMMUNICATE WITH AREA 2. Areas touching routers are,,
A { A2 }
B { A2, A1 }
C { A1, A0 }
Virtual Link will create between B and C because both routers have same area (A1) and a backbone area (A0) also.

GO TO "B"
B(config)#router ospf 1
B(config-router)#area 1 virtual-link 33.3.3.3
!
GO TO "C"
C(config)#router ospf 1
c(config-router)#area 1 virtual-link 22.2.2.2

Now see convergence is complete, and u can ping any network in this topology.

2009-06-25T22:45:00.001-07:00

My first experience was in Berltiz Language Center as a Network Admin where mostly the issue arise due to unavailability of internet and this is because of Load Shedding, so what to do, what to do......people are waiting for there online test and no internet, than RESTARTED DSL router and all in a sudden packets start moving, up up up everywhere, all LAN nodes start smiling with google homepages.....

......kamyab ho gya........

Now i got a chance to work in an organization where i am an application support engineer for an application (solution provided to MNC), the issue arise when exception start coming in log, what to do what to do, restart the oracle services as well as application services and walla exception is removed, issue is solved mostly 80 percent exceptions are removed by restarting service if not than restart the server, and it will work for u.

Moral

Once you have configured the server end, and whenever there is an issue first solution is RESTART, after that you have to think something out of the box or RESTART again :)

What is RIR and APNIC

2008-12-22T07:18:00.000-08:00

Regional Internet Registries (RIRs) manage, distribute, and register public, numeric Internet address space (and related resources) within their respective regions.

There are currently five RIRs in the world:

IR	Region served
APNIC	Asia Pacific
RIPE NCC	Europe and the Middle-East
ARIN	Northern America and sub-Saharan Africa
LACNIC	Latin America and the Carribean
AfriNIC	Africa

RIRs were originally established under the authority of IANA (Internet Assigned Numbers Authority) to serve and represent large geographical regions. IANA delegates large ranges of Internet resources to the RIRs, which then allocate the resources within their regions. The RIRs work closely with each other and others to develop consistent policies and promote best current practice for the Internet. Watch this video which will demonstrate its location and working for more clarity and description..

Configure Network Bridge

2008-12-12T10:39:00.000-08:00

Network Bridging provides an easy way to connect two or more networks to become a single big network without using router in order to share file, printer or Internet connection. Please note that all computers in different network that needs to be bridged must sit in same logical IP Network.

On the system with multiple network adapters :
In the properties of "My Network Places",
right-click on a network connection to display the context menu : "Bridge Connections"

You will get the warning : "To create a Network Bridge, you must select at least two network connections that are not being used by Internet Connection Sharing or the Internet Connection Firewall"

You need to select multiple Network connections : select with a single click the first network connection - hold down the Ctrl-key and select with a single click the second (or more) network connections - right-click and selects now from the pop-up/Context menu to "Bridge Connections"

You will get for a while a message: "please wait while Windows bridges the connections"

Windows will create the "Network Bridge", which for a few seconds will be shown with "Network "
