Pakistan cricketers' DNA tested in Woolmer murder probe


Pakistan's World Cup cricketers provided DNA samples today as Jamaican police probed the murder of their coach Bob Woolmer and awaited results of tests on his body for more clues on how he died.
Yesterday, Jamaican police had revealed that Woolmer, 58, one of the most famous figures in the game, had been strangled.
The news sent shock waves through cricket -- a sport still concentrated in former British colonies -- and completely overshadowed the action in the ninth edition of the 32-year-old tournament.
Jamaican police said that they had yet to receive toxicology and histology (study of body tissue) reports from tests on Woolmer's body.
The coroner said the body would not be released until after an inquest.

Sri Lanka destroys India’s World Cup hopes

Mar 23, Port-of-Spain, Trinidad- India’s hopes of getting into the super 8 round in the World Cup cricket vanished today when Sri Lanka beat India by 69 runs at the Queen's Park Oval today. India was all out for 185 in 43 overs.
Opening batsman Upul Tharanga and Chamara Silva guided Sri Lanka to 254 for six against India in the decisive match to set a target of 255 for India.
India needed to win this match after losing to Bangladesh earlier to avoid elimination in the first round. India's only chance of entering the next stage is if Bangladesh lost to Bermuda in next Sunday's match which is an unlikely outcome. Neighbouring Pakistan was also eliminated in the first round.

Bob Woolmer's death stuns cricket world


A pall of gloom fell over the World Cup following the death of Bob Woolmer, the Pakistan coach, in hospital in Jamaica on Sunday, hours after he was found unconscious on the floor of his hotel room. He was 58.
Tributes poured in from across the cricketing world, where Woolmer was known as an innovative coach and a scholar of the game. The Pakistan team, already eliminated from the World Cup on Saturday, said it would play its final match, against Zimbabwe, on Wednesday as scheduled.
"We've been speaking to the doctors and they think it is either stress or a heart attack," Russell Woolmer, his son, told South African radio from Cape Town. "There was a lot of stress in his job and it may have been stress that caused it. We're all very shocked and we don't know what to do."
The news of Woolmer's death was announced by Pervez Mir, Pakistan's media manager, a couple of hours after it first became known that he had been taken ill. "Bob Woolmer has passed away. I am speaking from the hospital and all the team management is also at the hospital. Doctors have pronounced him dead. Bob has passed away and it is very shocking news to all of the team and the team management.
"Bob's family and wife were informed by the management about his condition when he was brought to hospital", Mir said, adding that Woolmer's wife was on her way from South Africa.
Mir's statement added that there would be a coroner's inquest and, in keeping with Jamaican law, an autopsy to determine the cause of death. Woolmer, a diabetic, was found unconscious on his hotel-room floor at around 10.45am after team officials grew concerned that they had not seen him since the previous evening. Mir said he had blood on him and there was vomit on the walls.
Karl Angell, director of communication for the Jamaica Constabulary Force, said Woolmer was pronounced dead by doctors at the University Hospital of the West Indies in Kingston, where he had been rushed to, at 12.14pm on Sunday.
Woolmer's death comes less than 24 hours after Pakistan were knocked out of the World Cup following their defeat by Ireland. After the match, Woolmer spoke of the pressures of coaching. "Doing it internationally, it takes a toll on you," he said. "The endless travelling and the non-stop living out of hotels.
"I am deeply hurt and cannot tell you how it is going to affect me," Woolmer told AFP late on Saturday after the Ireland defeat, saying he would answer more questions on email later in the week.
Mir said Pakistan would still play their final World Cup group match on Wednesday. "The Pakistan team will continue its participation in the tournament. We are due to play Zimbabwe and we will play that match," Mir told AFP by telephone from Jamaica. "Obviously the boys are extremely sad, they are very distrurbed, they are shocked, but the boys have to play the match and they will."

What is UNIX?

  • UNIX is an operating system which was first developed in the 1960s, and has been under constant development ever since. By operating system, we mean the suite of programs which make the computer work. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops.
  • UNIX systems also have a graphical user interface (GUI) similar to Microsoft Windows which provides an easy to use environment. However, knowledge of UNIX is required for operations which aren't covered by a graphical program, or for when there is no windows interface available, for example, in a telnet session
  • There are many different versions of UNIX, although they share common similarities. The most popular varieties of UNIX are Sun Solaris, GNU/Linux, and MacOS X.

The UNIX operating system is made up of three parts; the kernel, the shell and the programs.


Kernel:
The kernel of UNIX is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls. As an illustration of the way that the shell and the kernel work together, suppose a user types rm myfile (which has the effect of removing the file myfile). The shell searches the filestore for the file containing the program rm, and then requests the kernel, through system calls, to execute the program rm on myfile. When the process rm myfile has finished running, the shell then returns the UNIX prompt % to the user, indicating that it is waiting for further commands.


Shell:
The shell acts as an interface between the user and the kernel. When a user logs in, the login program checks the username and password, and then starts another program called the shell. The shell is a command line interpreter (CLI). It interprets the commands the user types in and arranges for them to be carried out. The commands are themselves programs: when they terminate, the shell gives the user another prompt (% on our systems). The adept user can customise his/her own shell, and users can use different shells on the same machine. Staff and students in the school have the tcsh shell by default. The tcsh shell has certain features to help the user inputting commands. Filename Completion - By typing part of the name of a command, filename or directory and pressing the [Tab] key, the tcsh shell will complete the rest of the name automatically. If the shell finds more than one name beginning with those letters you have typed, it will beep, prompting you to type a few more letters before pressing the tab key again. History - The shell keeps a list of the commands you have typed in. If you need to repeat a command, use the cursor keys to scroll up and down the list or type history for a list of previous commands.

Files and processes

Everything in UNIX is either a file or a process.
A process is an executing program identified by a unique PID (process identifier).
A file is a collection of data. They are created by users using text editors, running compilers etc.
Examples of files:
a document (report, essay etc.)
the text of a program written in some high-level programming language
instructions comprehensible directly to the machine and incomprehensible to a casual user, for example, a collection of binary digits (an executable or binary file);
a directory, containing information about its contents, which may be a mixture of other directories (subdirectories) and ordinary files.
