Impian..
Adakah impian itu mimpian semata-mata?....Apabila terpandang sahaja perkataan Impian,terlantas dalam fikiran saya akan satu rancangan televisyen kesukaan seisi keluarga saya yang amat popular pada masa beberapa tahun lalu,iaitu rancangan "Casa Impian".
"Casa Impian" merupakan satu rancangan tv yang memaparkan idea dan tutorial dalam men"decorate"kan tempat tinggal anda.Dalam rancangan tersebut,hanya individu yang betul-betul bertuah sahaja akan dipilih kerana segala kos dan tanggungan pengubahsuaian akan ditaja dan ditanggung seratus peratus oleh pihak pengurusan.Ruang yang major seperti ruang tamu,bilik,dapur akan diubahsuaikan mengikut impian dan citarasa anda.Ramai yang ingin menjadi salah seorang daripada individu yang bertuah rancangan tersebut dan sentiasa mengalu-alukan kedatangan kru kasa impian tersebut,haha.Secara tidak langsung,rancangan tersebut memberikan inspirasi kepada saya bahawa untuk mengecapi impian dan mendapatkan sesuatu kadang-kala memerlukan "luck" juga.
Definisi impian kepada saya tidaklah begitu menyeluruh sekali,untuk saya, impian itu cuma merupakan kenyataan yang tidak mungkin termaktub ataupun tertunai dalam hidup saya,impian tersebut setakat memainkan peranan dalam memberi sokongan moral dalam kehidupan saya.Mungkin kerana impian saya tidak sesekali pun pernah terkabul.Saya percayai bahawa ramai yang mempunyai impiannya yang tersendiri.Tetapi tidak ramai yang berjaya menjadikan impian itu realiti.Tapi adakah impian itu boleh menolak kita ke depan?? ataupun impian itu kompas yang penting dalam kehidupan harian kita?.."Tanpa impian,kita tak kemana-mana".....??
Seperti manusia yang lain,saya mempunyai impian saya juga.Impian saya begitu ringkas,dan saya tidak pernah pun berfikir untuk menjadi seorang jutawan yang kaya-raya ataupun memiliki harta dan kekayaan yang melambak dan sebagainya.Sejak kecil lagi saya bertegas dan berhasrat untuk menjadi seorang..........XXXXX...saya mengategorikan cita-cita tersebut sebagai impian saya...mungkin tidak ramai yang mengetahuinya....
Walaopun saya pernah berkobar-kobar dan bertungkus-lumus memburunya,Tetapi ia tetap menjadi satu agenda "berangan-angan"........Dan saya tidak pernah berasa kesal kerana memilih impian tersebut sebagai "impian"....

History of passwords.....
Passwords or watchwords have been used since ancient times.Polybius describes the system for distribution watchwords in the Roman military as follows:
The way in which they secure the passing round of the watchword for the night is as follows: from the tenth maniple of each class of infantry and cavalry, the maniple which is encamped at the lower end of the street, a man is chosen who is relieved from guard duty, and he attends every day at sunset at the tent of the tribune, and receiving from him the watchword - that is a wooden tablet with the word inscribed on it - takes his leave, and on returning to his quarters passes on the watchword and tablet before witnesses to the commander of the next maniple, who in turn passes it to the one next him. All do the same until it reaches the first maniples, those encamped near the tents of the tribunes. These latter are obliged to deliver the tablet to the tribunes before dark. So that if all those issued are returned, the tribune knows that the watchword has been given to all the maniples, and has passed through all on its way back to him. If any one of them is missing, he makes inquiry at once, as he knows by the marks from what quarter the tablet has not returned, and whoever is responsible for the stoppage meets with the punishment he merits. [2].
Passwords have been used with computers since the earliest days of computing. MIT's CTSS, one of the first time sharing systems, was introduced in 1961. It had a LOGIN command that requested a user password. "After typing PASSWORD, the system turns off the printing mechanism, if possible, so that the user may type in his password with privacy." [3] Robert Morris invented the idea of storing login passwords in a hashed form as part of the Unix operating system. His algorithm, know as crypt(3), used a 12-bit salt and invoked a modified form of the DES algorithm 25 times to reduce the risk of dictionary attacks.
