Movie to see
1. The proposal :
To see use : http://www.imdb.com/title/tt1041829/
The Proposal is a romantic comedy starring Sandra Bullock and Ryan Reynolds directed by Anne Fletcher. Margaret Tate (Sandra Bullock) is the executive editor-in-chief of a book publishing company, Colden Books, who forces her assistant Andrew Paxton (Ryan Reynolds) to marry her in order to avoid being deported to Canada. He grudgingly accepts, under the condition that he is promoted to the position of editor. When the government investigates, the two are forced to spend the weekend with his parents in Alaska in order to sell the lie.
The unlikely couple heads to Alaska to meet his quirky family and the always-in-control city girl finds herself in one comedic fish-out-of-water situation after another. With an impromptu wedding in the works and an immigration official on their tails, Margaret and Andrew reluctantly vow to stick to the plan despite the precarious consequences. The family suggests they could marry the same weekend, and they reluctantly accept. They start to fall genuinely in love as they spend more and more time together.
Because of this, during the wedding ceremony, Margaret decides she cannot do this to Andrew and confesses the business arrangement in front of everyone--including the immigration officer handling their case. She is then told that she has 24 hours to get back to Canada, and thus goes back to New York to pack her things. Upon doing so, however, Andrew shows up at the office and confesses his love for her in front of the entire office staff, proposing marriage all over again.
Michael Mosley, Dale Place, Alicia Hunt, Oscar Nunez, Mary Steenburgen, Craig T. Nelson, Betty White, Denis O Hare and Aasif Mandvi also starrs.
2. Twilight :
Use : http://www.imdb.com/title/tt1099212/TWILIGHT is an action-packed, modern day love story between a vampire and a human. Bella Swan (Kristen Stewart) has always been a little bit different, never caring about fitting in with the trendy girls at her Phoenix high school. When her mother remarries and sends Bella to live with her father in the rainy little town of Forks, Washington, she doesn’t expect much of anything to change. Then she meets the mysterious and dazzlingly beautiful Edward Cullen (Robert Pattinson), a boy unlike any she’s ever met. Intelligent and witty, he sees straight into her soul. Soon, Bella and Edward are swept up in a passionate and decidedly unorthodox romance. Edward can run faster than a mountain lion, he can stop a moving car with his bare hands - and he hasn’t aged since 1918. Like all vampires, he’s immortal. But he doesn’t have fangs, and he doesn’t drink human blood; Edward and his family are unique among vampires in their lifestyle choice. To Edward, Bella is that thing he has waited 90 years for - a soul mate. But the closer they get, the more Edward must struggle to resist the primal pull of her scent, which could send him into an uncontrollable frenzy. But what will Edward & Bella do when James (Cam Gigandet), Laurent (Edi Gathegi) and Victoria (Rachelle Lefevre), the Cullens’ mortal vampire enemies, come to town, looking for her?

EJB overview
EJB Overview
Session beans execute a particular business task on behalf of a single client during a single
session. Session beans can be stateful or stateless, but are not persistent; when a client finishes
with a session bean, the bean goes away.
Entity beans represent business objects in a data store, usually a relational database system.
Persistence—loading and saving data—can be bean-managed or container-managed. More than
just an in-memory representation of a data object, entity beans have methods that model the
behaviors of the business objects they represent. Entity beans can be accessed concurrently by
multiple clients and they are persistent by definition.
The container creates an instance of the message-driven bean or it assigns one from a pool to
process the message. When the message is received in the JMS Destination, the message-driven
bean assigns an instance of itself from a pool to process the message. Message-driven beans are
not associated with any client. They simply handle messages as they arrive.

useradd command UNIX
DESCRIPTION
The useradd command creates a user login on the system by adding the
appropriate entry to the /etc/passwd file and any security files,
modifying the /etc/group file as necessary, creating a home directory,
and copying the appropriate default files into the home directory
depending on the command line options. The new login remains locked
until the passwd (see passwd(1)) command is invoked.
New Behavior
login will not be added to the primary group entry in the /etc/group
file, even if the primary group is specified in the command line.
However, the login is added to the corresponding supplemental group
in /etc/group file.
Options
The useradd command supports the following options:
-u uid Specifies the UID for the new user. uid must be a
non-negative decimal integer less than MAXUID as
it is defined in the <param.h> header file. uid
defaults to the next available unique number above
the maximum currently assigned number. UIDs from
0-99 are reserved.
-o Allows the UID to be non-unique (i.e., a
duplicate).
-g group Specifies the integer group ID or character string
name of an existing group. This defines the
primary group membership of the new login. The
default for this option can be reset by invoking
useradd -D -g group.
-G group Specifies the integer group ID or character string
name of an existing group. This defines the
supplemental group memberships of the new login.
Multiple groups may be specified as a comma
separated list. Duplicates within group with the
-g and -G options are ignored.
RETURN VALUE
useradd exits with one of the following values:
0 Successful completion.
2 Invalid command syntax.
3 Invalid argument supplied to an option.
4 uid is not unique (when -o is not used).
6 The group specified with the -g option does not exist.
9 login is not unique.
10 Cannot modify the /etc/group file. The login was added to
the /etc/passwd file, but not to the /etc/group file.
12 Unable to create the home directory (while using the -m
option) or unable to complete the copy of skel_dir to the
new home directory.
13 Unable to open /etc/ptmp file or /etc/default file, or
/etc/passwd file is non-existent.
14 /etc/passwd, or /etc/ptmp, or /etc/default file busy.
Another command may be modifying the /etc/passwd file.
16 Cannot add the entry into the /etc/passwd file.
54 Exceeding permissible limit of maximum members in a group.
The /etc/group file is not modified.
