Lenovo ThinkPad W700ds (lenovo)
Lenovo memperkenalkan ThinkPad W700ds. Laptop ini menjadi unik karena adanya layar kedua yang dapat dikeluarkan untuk menjadikan laptop ini berlayar ganda.
Seri ThinkPad dari Lenovo dikenal sebagai seri untuk komputer pekerja (Mobile Workstation). W700ds dengan fitur layar gandanya diklaim cocok bagi pengguna yang bekerja di bidang kreasi konten digital, eksplorasi minyak dan gas, Computer Aided Design (CAD) dan fotografi.
Ddari keterangan tertulis Lenovo yang diterima, Rabu (21/1/2009), sebuah penelitian menyebutkan bekerja dengan layar ekstra akan membantu pengguna untuk memaksimalkan produktivitas.
Layar kedua pada W700ds berukuran sekitar 40 persen dari layar utama yang berukuran 17 inchi. Layar kedua ini ditarik keluar dari bagian belakang layar utama dan bisa diatur sudutnya hingga 30 derajat, mirip kaca spion.
Dengan penekanan pada pekerja di bidang grafis, Lenovo pun menyediakan pilihan isi perut W700ds. Mulai dari prosesor Intel mobile Quad Core Core 2 Extreme, dual hard drive, kartu grafis mobile NVidia Quadro FX hingga memori DDR 3 maksimal 8 Gigabyte bisa didapatkan jika pengguna menghendaki.
Pilihan lainnya adalah Wacom Digitizer yang bisa tersedia langsung bersama laptop tersebut. Digitizer itu terletak di dekat area touchpad dan dilengkapi dengan pena untuk input gambar.

User Datagram Protocol
Introduction
------------
This User Datagram Protocol (UDP) is defined to make available a
datagram mode of packet-switched computer communication in the
environment of an interconnected set of computer networks. This
protocol assumes that the Internet Protocol (IP) [1] is used as the
underlying protocol.
This protocol provides a procedure for application programs to send
messages to other programs with a minimum of protocol mechanism. The
protocol is transaction oriented, and delivery and duplicate protection
are not guaranteed. Applications requiring ordered reliable delivery of
streams of data should use the Transmission Control Protocol (TCP) [2].
Format
------
0 7 8 15 16 23 24 31
+--------+--------+--------+--------+
| Source | Destination |
| Port | Port |
+--------+--------+--------+--------+
| | |
| Length | Checksum |
+--------+--------+--------+--------+
|
| data octets ...
+---------------- ...
User Datagram Header Format
Fields
------
Source Port is an optional field, when meaningful, it indicates the port
of the sending process, and may be assumed to be the port to which a
reply should be addressed in the absence of any other information. If
not used, a value of zero is inserted.
Fields
Destination Port has a meaning within the context of a particular
internet destination address.
Length is the length in octets of this user datagram including this
header and the data. (This means the minimum value of the length is
eight.)
Checksum is the 16-bit one's complement of the one's complement sum of a
pseudo header of information from the IP header, the UDP header, and the
data, padded with zero octets at the end (if necessary) to make a
multiple of two octets.
The pseudo header conceptually prefixed to the UDP header contains the
source address, the destination address, the protocol, and the UDP
length. This information gives protection against misrouted datagrams.
This checksum procedure is the same as is used in TCP.
0 7 8 15 16 23 24 31
+--------+--------+--------+--------+
| source address |
+--------+--------+--------+--------+
| destination address |
+--------+--------+--------+--------+
| zero |protocol| UDP length |
+--------+--------+--------+--------+
If the computed checksum is zero, it is transmitted as all ones (the
equivalent in one's complement arithmetic). An all zero transmitted
checksum value means that the transmitter generated no checksum (for
debugging or for higher level protocols that don't care).
User Interface
--------------
A user interface should allow
the creation of new receive ports,
receive operations on the receive ports that return the data octets
and an indication of source port and source address,
and an operation that allows a datagram to be sent, specifying the
data, source and destination ports and addresses to be sent.
IP Interface
-------------
The UDP module must be able to determine the source and destination
internet addresses and the protocol field from the internet header. One
possible UDP/IP interface would return the whole internet datagram
including all of the internet header in response to a receive operation.
Such an interface would also allow the UDP to pass a full internet
datagram complete with header to the IP to send. The IP would verify
certain fields for consistency and compute the internet header checksum.
Protocol Application
--------------------
The major uses of this protocol is the Internet Name Server [3], and the
Trivial File Transfer [4].
Protocol Number
---------------
This is protocol 17 (21 octal) when used in the Internet Protocol.
Other protocol numbers are listed in [5].
Pidato Barack Obama....
Forty-four Americans have now taken the presidential oath. The words have been spoken during rising tides of prosperity and the still waters of peace. Yet, every so often the oath is taken amidst gathering clouds and raging storms. At these moments, America has carried on not simply because of the skill or vision of those in high office, but because we the people have remained faithful to the ideals of our forebears, and true to our founding documents.
So it has been. So it must be with this generation of Americans.
That we are in the midst of crisis is now well understood. Our nation is at war, against a far-reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our health care is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.
These are the indicators of crisis, subject to data and statistics. Less measurable but no less profound is a sapping of confidence across our land — a nagging fear that America's decline is inevitable, and that the next generation must lower its sights.
Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America — they will be met.
On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord.
On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics.
We remain a young nation, but in the words of scripture, the time has come to set aside childish things. The time has come to reaffirm our enduring spirit; to choose our better history; to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free and all deserve a chance to pursue their full measure of happiness.
In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of shortcuts or settling for less. It has not been the path for the faint-hearted — for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things — some celebrated but more often men and women obscure in their labor, who have carried us up the long, rugged path towards prosperity and freedom.
For us, they packed up their few worldly possessions and traveled across oceans in search of a new life.
For us, they toiled in sweatshops and settled the West; endured the lash of the whip and plowed the hard earth.
For us, they fought and died, in places like Concord and Gettysburg; Normandy and Khe Sahn.
Time and again these men and women struggled and sacrificed and worked till their hands were raw so that we might live a better life. They saw America as bigger than the sum of our individual ambitions; greater than all the differences of birth or wealth or faction.
This is the journey we continue today. We remain the most prosperous, powerful nation on Earth. Our workers are no less productive than when this crisis began. Our minds are no less inventive, our goods and services no less needed than they were last week or last month or last year. Our capacity remains undiminished. But our time of standing pat, of protecting narrow interests and putting off unpleasant decisions — that time has surely passed. Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America.
For everywhere we look, there is work to be done. The state of the economy calls for action, bold and swift, and we will act — not only to create new jobs, but to lay a new foundation for growth. We will build the roads and bridges, the electric grids and digital lines that feed our commerce and bind us together. We will restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost. We will harness the sun and the winds and the soil to fuel our cars and run our factories. And we will transform our schools and colleges and universities to meet the demands of a new age. All this we can do. And all this we will do.
Now, there are some who question the scale of our ambitions — who suggest that our system cannot tolerate too many big plans. Their memories are short. For they have forgotten what this country has already done; what free men and women can achieve when imagination is joined to common purpose, and necessity to courage.
What the cynics fail to understand is that the ground has shifted beneath them — that the stale political arguments that have consumed us for so long no longer apply. The question we ask today is not whether our government is too big or too small, but whether it works — whether it helps families find jobs at a decent wage, care they can afford, a retirement that is dignified. Where the answer is yes, we intend to move forward. Where the answer is no, programs will end. And those of us who manage the public's dollars will be held to account — to spend wisely, reform bad habits, and do our business in the light of day — because only then can we restore the vital trust between a people and their government.
Nor is the question before us whether the market is a force for good or ill. Its power to generate wealth and expand freedom is unmatched, but this crisis has reminded us that without a watchful eye, the market can spin out of control — and that a nation cannot prosper long when it favors only the prosperous. The success of our economy has always depended not just on the size of our gross domestic product, but on the reach of our prosperity; on our ability to extend opportunity to every willing heart — not out of charity, but because it is the surest route to our common good.
As for our common defense, we reject as false the choice between our safety and our ideals. Our founding fathers, faced with perils we can scarcely imagine, drafted a charter to assure the rule of law and the rights of man, a charter expanded by the blood of generations. Those ideals still light the world, and we will not give them up for expedience's sake. And so to all other peoples and governments who are watching today, from the grandest capitals to the small village where my father was born: know that America is a friend of each nation and every man, woman, and child who seeks a future of peace and dignity, and that we are ready to lead once more.
Recall that earlier generations faced down fascism and communism not just with missiles and tanks, but with sturdy alliances and enduring convictions. They understood that our power alone cannot protect us, nor does it entitle us to do as we please. Instead, they knew that our power grows through its prudent use; our security emanates from the justness of our cause, the force of our example, the tempering qualities of humility and restraint.
We are the keepers of this legacy. Guided by these principles once more, we can meet those new threats that demand even greater effort — even greater cooperation and understanding between nations. We will begin to responsibly leave Iraq to its people, and forge a hard-earned peace in Afghanistan. With old friends and former foes, we will work tirelessly to lessen the nuclear threat, and roll back the specter of a warming planet. We will not apologize for our way of life, nor will we waver in its defense, and for those who seek to advance their aims by inducing terror and slaughtering innocents, we say to you now that our spirit is stronger and cannot be broken; you cannot outlast us, and we will defeat you.
For we know that our patchwork heritage is a strength, not a weakness. We are a nation of Christians and Muslims, Jews and Hindus — and non-believers. We are shaped by every language and culture, drawn from every end of this Earth; and because we have tasted the bitter swill of civil war and segregation, and emerged from that dark chapter stronger and more united, we cannot help but believe that the old hatreds shall someday pass; that the lines of tribe shall soon dissolve; that as the world grows smaller, our common humanity shall reveal itself; and that America must play its role in ushering in a new era of peace.
To the Muslim world, we seek a new way forward, based on mutual interest and mutual respect. To those leaders around the globe who seek to sow conflict, or blame their society's ills on the West — know that your people will judge you on what you can build, not what you destroy. To those who cling to power through corruption and deceit and the silencing of dissent, know that you are on the wrong side of history; but that we will extend a hand if you are willing to unclench your fist.
To the people of poor nations, we pledge to work alongside you to make your farms flourish and let clean waters flow; to nourish starved bodies and feed hungry minds. And to those nations like ours that enjoy relative plenty, we say we can no longer afford indifference to suffering outside our borders; nor can we consume the world's resources without regard to effect. For the world has changed, and we must change with it.
As we consider the road that unfolds before us, we remember with humble gratitude those brave Americans who, at this very hour, patrol far-off deserts and distant mountains. They have something to tell us today, just as the fallen heroes who lie in Arlington whisper through the ages. We honor them not only because they are guardians of our liberty, but because they embody the spirit of service; a willingness to find meaning in something greater than themselves. And yet, at this moment — a moment that will define a generation — it is precisely this spirit that must inhabit us all.
For as much as government can do and must do, it is ultimately the faith and determination of the American people upon which this nation relies. It is the kindness to take in a stranger when the levees break, the selflessness of workers who would rather cut their hours than see a friend lose their job which sees us through our darkest hours. It is the firefighter's courage to storm a stairway filled with smoke, but also a parent's willingness to nurture a child, that finally decides our fate.
Our challenges may be new. The instruments with which we meet them may be new. But those values upon which our success depends — hard work and honesty, courage and fair play, tolerance and curiosity, loyalty and patriotism — these things are old. These things are true. They have been the quiet force of progress throughout our history. What is demanded then is a return to these truths. What is required of us now is a new era of responsibility — a recognition, on the part of every American, that we have duties to ourselves, our nation, and the world, duties that we do not grudgingly accept but rather seize gladly, firm in the knowledge that there is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task.
This is the price and the promise of citizenship.
This is the source of our confidence — the knowledge that God calls on us to shape an uncertain destiny.
This is the meaning of our liberty and our creed — why men and women and children of every race and every faith can join in celebration across this magnificent mall, and why a man whose father less than sixty years ago might not have been served at a local restaurant can now stand before you to take a most sacred oath.
So let us mark this day with remembrance, of who we are and how far we have traveled. In the year of America's birth, in the coldest of months, a small band of patriots huddled by dying campfires on the shores of an icy river. The capital was abandoned. The enemy was advancing. The snow was stained with blood. At a moment when the outcome of our revolution was most in doubt, the father of our nation ordered these words be read to the people:
"Let it be told to the future world ... that in the depth of winter, when nothing but hope and virtue could survive...that the city and the country, alarmed at one common danger, came forth to meet (it)." America, in the face of our common dangers, in this winter of our hardship, let us remember these timeless words. With hope and virtue, let us brave once more the icy currents, and endure what storms may come. Let it be said by our children's children that when we were tested we refused to let this journey end, that we did not turn back nor did we falter; and with eyes fixed on the horizon and God's grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations.

Film-Film Terbaik 2009
Cukup banyak film-film yang menjanjikan, dan kelihatannya bakal mengasyikkan untuk ditonton pada 2009 ini. Memang tidak pasti bagus, tapi saya bisa berekspektasi lebih setelah melihat trailer-trailernya. Apalagi, cukup banyak sutradara-sutradara favorit saya yang kembali menorehkan karyanya. Istimewa. Skala 1-5 bintang ini menunjukkan seberapa ingin saya menontonnya.
Public Enemies
Saya jelas akan mencatat jadwal premiere film ini di Jakarta nanti. Betapa tidak, dua aktor favorit saya, Johnny Depp dan Christian Bale akan dilawankan dalam film arahan Michael Mann (Miami Vice, Collateral, Ali, The Insider, Heat) si rajanya action-thriller. Film ini docomot dari novel laris Public Enemies: America’s Greatest Crime, jadi paling tidak punya plot dan struktur alur terjamin. Ceritanya, Bale akan menjadi agen FBI, sementara Depp memerankan bad guys-nya, si perampok bank. Arggghhh…. Keren keren keren.
*****
Star Trek
Jujur, saya cuma nonton Star Trek era Captain Picard saja. Data si android, bukan Mr Spock 
***
Confession of a Shopaholic
This is definately not my cup of cofee. Tapi, yah, lumayan jadi pilihan saat ingin mengajak seorang cewek nonton. Mereka pasti suka. Haha. Dan rasanya tidak ada ruginya bagi cowok mengetahui bagaimana kegilaan para wanita dengan belanja. haha.
*
The Watchmen
Konon, dewanya komik ini terlalu gelap untuk dijadikan film. Sebab, ceritanya bak menyatukan air dan minyak. Yakni sebuah film superhero yang geral, dipenuhi berbagai intrik dan konspirasi politik.
Sutradara yang berani memegang risiko sedemikian besar ini adalah Zack Snyder (300, Dawn of the Dead). Melihat perkembangan Zack yang begitu pesat, saya yakin dia tidak akan mengecewakan fans fanatik The Watchmen. You go Zack!
****
Slumdog Millionaire
Saya tak perlu tahu trailernya, tak perlu tahu ceritanya, selama itu disutradarai Danny Boyle, pasti saya tonton. Begitu dirilis, Slumdog sudah mendapat ulasan sangat positif dan disebut sebagai kandidat film terbaik beberapa festival besar. “Our feel-good movie of the year” sebut seorang kritikus.
*****
Ice Age 3
Tingkah laku kocak mahluk-mahluk zaman es yang disuarakan Ray Romano dkk ini tetap menggoda. Toh, Madagascar saja bisa jauh lebih baik di seri keduanya. Kenapa Ice Age tidak?
**
Grand Turino
Ah, tak ada alasan kiranya untuk tidak berharap lebih terhadap torehan karya dari sang master, Clint Eastwood. Termasuk, ketika Eastwood memutuskan mengambil fokus pada cerita sehari-hari, yakni tentang seorang veteran perang versus geng remaja lokal. Saatnya belajar dari yang terbaik.
****
Up
Siap-siap tertawa sepanjang bioskop, karena ini film terbaru Pixar Animation Studios.
Sutradaranya, Pete Docter, adalah otak kreatif dibalik Monster Inc., film Pixar yang menurut saya paling lucu dan segar. Ceritanya soa… ah sudah-sudah, I don’t want to spoil the fun. Yang jelas, film ini wajib tonton di bioskop!
*****
Valkyrie
Adolf Hitler adalah ancaman bagi dunia dan harus dihabisi. Dan ini adalah cerita tentang konspirasi plot penghianatan sekaligus tim khusus yang harus menghabisi sang diktator. Dibintangi Tom Cruise dan disutradarai oleh Brian Singer (X-Men, X2). Promosinya digeber cukup kencang. Semoga saja Singer tak mengecewakan kita seperti pada Superman Returns.
***
Night at the Museum 2: Battle of the Smithsonian
Didesain untuk menghasilkan tawa secara intens, akting Ben Stiller membuat Night at The Museum sebagai film yang konstan fun. Penonton setuju, mengantar film bergenre adventure comedy ini meraih penghasilan USD500 juta. Wow. Jadi, tak ada alasan bagi studio 20th Century Fox untuk membuat sekuelnya. Dengan koridor sama, gimmick berbeda. Masih melibatkan museum, tengkorak T-Rex, Stiller (tentu saja), dan yang baru, hewan-hewan air.
**
2012
Jika ingin tahu bagaimana dampak Global Warming pada kota New York, tontonlah The Day After Tomorrow. Dan sekarang, masternya film bencana berkandungan blockbuster, Roland Emmerich, melabuhkan karya terbarunya. Trailer 2012 terlihat mengerikan, seorang biksu dipuncak gunung menyaksikan tsunami melahap gunung secara masif. Whoa. Kalau ternyata bagus, saya akan memaafkan Emmerich akan kegagalannya dalam 10,000 BC.
***
X-Men Origins: Wolverine
Di komik aslinya, Wolverine digembarkan sebagai sosok antihero yang sadis dan brutal. Entah, apakah sutradara Gavin Hood (Tsotsi) bakal menurut pada nuansa itu di film tetang asal mula si Logan ini. Kalau hasilnya seperti X-Men, ehm, saya bakal kecewa. Kita nantikan saja bagaiman duel kuku pancanaka adamantium dengan keganasan sang nemesis, Sabretooth. yeah.
****
Race To Witch Mountain
Meski sutradara Andy Fickman (She’s The Man) melabeli film ini sebagai “a very cool dark thriller”, tetap saja, Race To Witch Mountain berlabelkan Disney. Jadi lupakan ekspektasi macam-macam. Selain dibintangi Dwayne “The Rock” Johnson, film ini juga menampilkan si cantik AnnaSophia Robb. Yeah, saya sudah menduga dia akan mendapat peran besar setelah Bridge to Terabithia.
**
G-Force
Saya mengibaratkan produser Jerry Bruckheimer sebagai Rick Rubin, karena semua yang disentuhnya bakal laris dan sukses. Nicolas Cage, Bill Nighy, dan Penélope Cruz mengisi suara dalam film animasi yang ceritanya membuat tersenym. “The film revolves around a team of trained secret agent guinea pigs that take on a mission for the US government to stop an evil billionaire, who plans to destroy the world with household appliances,”. Bruckheimer akan mengarahkan apprentice-nya, sutradara debutan Hoyt Yeatman.
***
Terminator: Salvation
McG, yang dikenal memiliki formula untuk mengantar sebuah film mendaki cepat di box office, hati-hati benar saat diminta menyutradarai instalasi kelima Terminator buatan James Cameron ini. Ia mengambil pendekatan beda. Dalam film berkadar blockbuster tinggi ini, McG berhasil meyakinkan aktor Christian Bale. Kepada Bale, ia menjanjikan Terminator: Salvation sebagai film yang character driven, bukan special effect oriented. Maklum, Bale dikenal sangat perfeksionis, kerap meragukan, bahkan tak jarang mempertanyakan logika sebuah skenario. Dengan Bale sebagai John Connor, jelas menguprade terminator ke level berikutnya.
****
Transformer 2 : revenge of the fallen.
Sejak menyutradarai The Island, saya semakin menaruh harapan besar terhadap Michael Bay. Ia tak hanya keren mendeliver action berbalut cinta seperti Armageddon dan Pearl Harbour, tapi juga mampu gila-gilaan dalam Transformer yang kental spesial efek. Seru, intens, cepat, fun, mengejutkan, dan jelasnya mampu mewujudkan imajinasi fans terhadap duel Autobots dan Decepticons. Film kedua, kita harapkan duel lebih eksplosif serta kehadiran robot-robot organik yang semakin cool.
*****
Avatar
Di serial Entourage, saya ingat bagaimana Eric memarahi Vince saat tahu James Cameron menyutradarai Aquaman, sementara Vince malah menolak membintangi film tersebut. “Are you crazy? James Cameron belum tentu bikin film 10 tahun sekali tau!” komentar Eric.
Oke, saya ingatkan lagi, Cameron adalah kreator The Abyss, film yang menginspirasi ilmuwan untuk membuat kapal selam mini bawah laut. Oya, dia cuma sutradara Titanic, itu tuh, film terlaris sepanjang masa itu. Alien? ooh, itu cuma film yang mendefinisikan kembali bagaimana film sci-fi dibuat pada zamannya. Dan Terminator? ah sudahlah.
Tapi dengar kata Cameron soal Avatar, “ini seperti Magnum Opus saya”. Soal detil film berbasis 3-D itu, Cameron berujar “We’re creating an entire world, a complete ecosystem of phantasmagorical plants and creatures, and a native people with a rich culture and language”. Masih meragukan Avatar dan Cameron?
