Steve Jobs biography
Synopsis
Steve Jobs was born February 24, 1955, to two University of Wisconsin graduate students who gave him up for adoption. Smart but directionless, Jobs experimented with different pursuits before starting Apple Computers with Stephen Wozniak in the Jobs' family garage. Apple's revolutionary products, which include the iPod, iPhone and iPad, are now seen as dictating the evolution of modern technology.
Quotes
I would trade all of my technology for an afternoon with Socrates.
Early Life
Steven Paul Jobs was born on February 24, 1955, to Joanne Simpson and Abdulfattah "John" Jandali, two University of Wisconsin graduate students who gave their unnamed son up for adoption. His father, Abdulfattah Jandali, was a Syrian political science professor and his mother, Joanne Simpson, worked as a speech therapist. Shortly after Steve was placed for adoption, his biological parents married and had another child, Mona Simpson. It was not until Jobs was 27 that he was able to uncover information on his biological parents.
As an infant, Steven was adopted by Clara and Paul Jobs and named Steven Paul Jobs. Clara worked as an accountant and Paul was a Coast Guard veteran and machinist. The family lived in Mountain View within California's Silicon Valley. As a boy, Jobs and his father would work on electronics in the family garage. Paul would show his son how to take apart and reconstruct electronics, a hobby which instilled confidence, tenacity, and mechanical prowess in young Jobs.
While Jobs has always been an intelligent and innovative thinker, his youth was riddled with frustrations over formal schooling. In elementary school he was a prankster whose fourth grade teacher needed to bribe him to study. Jobs tested so well, however, that administrators wanted to skip him ahead to high school—a proposal his parents declined.
After he did enroll in high school, Jobs spent his free time at Hewlett-Packard. It was there that he befriended computer club guru Steve Wozniak. Wozniak was a brilliant computer engineer, and the two developed great respect for one another.
Apple Computers
After high school, Jobs enrolled at Reed College in Portland, Oregon. Lacking direction, he dropped out of college after six months and spent the next 18 months dropping in on creative classes. Jobs later recounted how one course in calligraphy developed his love of typography.
In 1974, Jobs took a position as a video game designer with Atari. Several months later he left Atari to find spiritual enlightenment in India, traveling the continent and experimenting with psychedelic drugs. In 1976, when Jobs was just 21, he and Wozniak started Apple Computers. The duo started in the Jobs family garage, and funded their entrepreneurial venture after Jobs sold his Volkswagen bus and Wozniak sold his beloved scientific calculator.
Jobs and Wozniak are credited with revolutionizing the computer industry by democratizing the technology and making the machines smaller, cheaper, intuitive, and accessible to everyday consumers. The two conceived a series of user-friendly personal computers that they initially marketed for $666.66 each. Their first model, the Apple I, earned them $774,000. Three years after the release of their second model, the Apple II, sales increased 700 percent to $139 million dollars. In 1980, Apple Computer became a publically traded company with a market value of $1.2 billion on the very first day of trading. Jobs looked to marketing expert John Scully of Pepsi-Cola to help fill the role of Apple's President.
Departure from Apple
However, the next several products from Apple suffered significant design flaws resulting in recalls and consumer disappointment. IBM suddenly surpassed Apple sales, and Apple had to compete with an IBM/PC dominated business world. In 1984 Apple released the Macintosh, marketing the computer as a piece of a counter culture lifestyle: romantic, youthful, creative. But despite positive sales and performance superior to IBM's PCs, the Macintosh was still not IBM compatible. Scully believed Jobs was hurting Apple, and executives began to phase him out.
In 1985, Jobs resigned as Apple's CEO to begin a new hardware and software company called NeXT, Inc. The following year Jobs purchased an animation company from George Lucas, which later became Pixar Animation Studios. Believing in Pixar's potential, Jobs initially invested $50 million of his own money into the company. Pixar Studios went on to produce wildly popular animation films such as Toy Story, Finding Nemo and The Incredibles. Pixar's films have netted $4 billion. The studio merged with Walt Disney in 2006, making Steve Jobs Disney's largest shareholder.
Reinventing Apple
Despite Pixar's success, NeXT, Inc. floundered in its attempts to sell its specialized operating system to mainstream America. Apple eventually bought the company in 1997 for $429 million. That same year, Jobs returned to his post as Apple's CEO.
Much like Steve Jobs instigated Apple's success in the 1970s, he is credited with revitalizing the company in the 1990s. With a new management team, altered stock options, and a self-imposed annual salary of $1 a year, Jobs put Apple back on track. His ingenious products such as the iMac, effective branding campaigns, and stylish designs caught the attention of consumers once again.
Pancreatic Cancer
In 2003, Jobs discovered he had a neuroendocrine tumor, a rare but operable form of pancreatic cancer. Instead of immediately opting for surgery, Jobs chose to alter his pescovegetarian diet while weighing Eastern treatment options. For nine months Jobs postponed surgery, making Apple's board of directors nervous. Executives feared that shareholders would pull their stocks if word got out that their CEO was ill. But in the end, Job's confidentiality took precedence over shareholder disclosure. In 2004, he had a successful surgery to remove the pancreatic tumor. True to form, in subsequent years Jobs disclosed little about his health.
Recent Innovations
Apple introduced such revolutionary products as the Macbook Air, iPod, and iPhone, all of which have dictated the evolution of modern technology. Almost immediately after Apple releases a new product, competitors scramble to produce comparable technologies. In 2007, Apple's quarterly reports were the company's most impressive statistics to date. Stocks were worth a record-breaking $199.99 a share, and the company boasted a staggering $1.58 billion dollar profit, an $18 billion dollar surplus in the bank, and zero debt.
In 2008, iTunes became the second biggest music retailer in America-second only to Wal-Mart. Half of Apple's current revenue comes from iTunes and iPod sales, with 200 million iPods sold and six billion songs downloaded. For these reasons, Apple has been rated No. 1 in America's Most Admired Companies, and No. 1 amongst Fortune 500 companies for returns to shareholders.
Personal Life
Early in 2009, reports circulated about Jobs' weight loss, some predicting his health issues had returned, which included a liver transplant. Jobs had responded to these concerns by stating he was dealing with a hormone imbalance. After nearly a year out of the spotlight, Steve Jobs delivered a keynote address at an invite-only Apple event September 9, 2009.
In respect to his personal life, Steve Jobs remained a private man who rarely discloses information about his family. What is known is Jobs fathered a daughter with girlfriend Chrisann Brennan when he was 23. Jobs denied paternity of his daughter Lisa in court documents, claiming he was sterile. Jobs did not initiate a relationship with his daughter until she was 7 but, when she was a teenager, she came to live with her father. In the early 1990s, Jobs met Laurene Powell at Stanford business school, where Powell was an MBA student. They married on March 18, 1991, and lived together in Palo Alto, California, with their three children.
Final Years
On October 5, 2011, Apple Inc. announced that co-founder Steve Jobs had died. He was 56 years old at the time of his death.

Nikon luncurkan D3100 : must have gadjet!!
Nikon D3100
Berikut spesifikasi lengkap dari Nikon D3100 :
sensor CMOS 14 MP (23.2 x 15.5 mm)
live View
Continuous AF pada video mode/live view
LCD 3 inci res 230k piksel (tidak bisa dilipat-putar/swivel)
ISO 100 – 12800
flash sync 1/200 detik
11 titik AF (multi CAM 1000)
Quiet Shutter Release Mode
usia shutter 100.000 kali pakai
420-pixel RGB 3D Color Matrix II metering sensor
HD Video 1920 x 1080p 24 fps dan 1280 x 720p 30 fps/24 fps
AVCHD video codec (H.264), HDMI out
EXPEED2 processor
pengguna bisa menyimpan picture profiles
video editing didalam kamera
burst 3 fps saja
Dari spesifikasi di atas nampak kalau D3100 ini merupakan perombakan besar-besaran dari D3000 seperti sensor CMOS 14 MP, ISO maksimal yang luar biasa tinggi di ISO 12800, full HD movie, live view dan prosesor EXPEED2. Bahkan dalam beberapa aspek D3100 ini bisa ‘mematikan’ penjualan kakaknya yaitu D5000. Melihat peningkatan yang pesat pada D3100 ini, ada dugaan Nikon akan menghentikan kelanjutan produk D5000 yang serba tanggung dalam hal fitur dan harga. Bisa jadi kedepannya Nikon hanya akan mengandalkan satu produk saja untuk mengisi segmen pemula (yaitu D3100 ini), sedangkan pada segmen semi-pro diprediksi Nikon juga akan melebur dua kelas yaitu D90 dan D300 (dirumorkan akan bernama D95). Kuat dugaan kebijakan ini diakibatkan oleh kondisi resesi ekonomi global yang memaksa produsen membuat segmentasi produk yang simpel dan jelas.

Tips Pemilihan Pompa Air Rumah Tangga
Posted at 16:57 by Handi
Banyak sekali jenis pompa air rumah tangga yang beredar di pasar, untuk dapat memilih pompa air yang tepat sebenarnya tidak terlalu sulit. Yang penting anda memiliki informasi yang akurat sebelum membeli. Tanpa informasi tersebut bukan anda saja yang bingung, toko penjual pompa pun akan bingung memilihkan pompa yang tepat untuk anda. Pada artikel ini kami akan menjelaskan informasi apa saja yang diperlukan, dan berdasarkan informasi tersebut pompa jenis apa saja yang dapat anda gunakan.
Informasi yang paling penting untuk anda ketahui adalah jenis sumber air, apakah berasal dari sumur bor, sumur gali, penampungan air? Setelah itu anda perlu mengetahui berapa kedalaman permukaan air sumber air terutama pada saat musim kemarau. Informasi mengenai kedalaman permukaan air seringkali salah, karena menurut pengalaman kami yang sering diberikan oleh konsumen adalah kedalaman sumur. Kedalaman sumur tentunya berbeda dengan kedalaman permukaan air. Yang pasti kedalaman sumur harus lebih dalam dari kedalaman permukaan air. Kedalaman permukaan air adalah jarak dari permukaan air hingga ke pompa air secara vertical. Untuk mengetahui kedalaman permukaan air, biasanya anda tinggal bertanya kepada tukang bor-nya. Biasanya mereka memiliki pengalaman untuk mengetahui berapa kedalaman permukaan air di tempat anda. Bila sumber air yang akan anda gunakan adalah sumber air yang lama, anda dapat mengukur sendiri ketinggian air dengan memasukkan paku yang diikat dengan benang. Anda harus mengulur dan menarik tali tersebut, hingga pada ketinggian tertentu paku tersebut basah.
Pada informasi spesifikasi pompa air, anda dapat membandingkan kedalaman permukaan air dengan informasi daya hisap. Tetapi anda tidak dapat 100% berpatokan dengan informasi daya hisap, karena umumnya standard yang digunakan oleh produsen pompa air adalah kedalaman permukaan air maksimal yng di mana air dapat terhisap. Maksimal belum tentu optimal, karena pada daya hisap maksimal, bisa jadi anda hanya mendapatkan air sejumlah 1 liter, dalam waktu 1 jam. Kami kira ini sangat tidak efisien. Oleh karena itu, di sini kami akan berusaha menyampaikan permukaan air yang optimal atau maksimal yang layak digunakan untuk masing-masing jenis pompa air. Dengan demikian anda memiliki gambaran pompa jenis apa yang tepat.
Bila kedalaman permukaan air kurang dari 7 meter, maka anda cukup menggunakan pompa sumur dangkal. Jenis pompa air sumur dangkal di sini dapat berjenis manual atau otomatis, dengan daya listrik 125 watt atau 200 watt. Pada pompa air sumur dangkal daya listrik yang lebih besar bukan berarti daya hisap semakin dalam, karena pada jenis pompa ini daya hisap optimal hanya hingga kurang lebih 7 meter. Dengan daya 200 watt, kapasitas air, dalam arti volume air yang dikeluarkan oleh pompa per jam, lebih besar daripada yang 125 watt. Pada informasi spesifikasi pompa air, rata-rata produsen mencantumkan daya hisap 9 meter, tetapi bila kedalaman permukaan air sumber air anda antara 7 hingga 9 meter, kami tidak menyarankan anda menggunakan pompa jenis ini. Perkecualian untuk pompa sumur dangkal merk Shimizu tipe PS-226 Bit dan PS-230 Bit, berdasarkan pengalaman kami, pompa shimizu tipe ini sanggup menghisap secara optimal hingga kedalaman 8 meter. Beberapa tukang pompa, juga dapat menyarankan anda untuk menggantung pompa air di dalam sumur (bila sumur berjenis sumur gali), untuk mengejar kedalaman permukaan air, sehingga anda dapat menghemat tanpa harus membeli pompa air tipe yang lebih tinggi dan tentunya lebih mahal. Tetapi anda harus mencermati, apakah kedalaman permukaan air sumur tersebut pada musim hujan dan kemarau berbeda jauh? Karena jangan sampai pada musim hujan, ketinggian permukaan air dapat merendam pompa air anda, yang akhirnya malah merusak pompa air anda.
Bila kedalaman permukaan sumber air anda berkisar antara 7 hingga 9 meter, kami menyarankan anda untuk menggunakan pompa air sumur dangkal tipe semi jet pump. Informasi spesifikasi daya hisap dari produsen umumnya mencantumkan 11 meter. Tetapi pompa semi jet pump lebih optimal untuk digunakan pada ketinggian permukaan air hingga 9 meter. Ini berlaku untuk pompa semi jet pump berdaya listrik 100 watt atau 250 watt. Seperti pompa air sumur dangkal, daya listrik yang lebih besar bukan berarti daya hisap yang lebih dalam, tetapi daya hisap yang lebih besar memiliki daya dorong yang lebih besar dan kapasitas air yang lebih besar pula. Pompa semi jet pump jarang sekali digantung di dalam sumur, karena umumnya terlalu berat, sehingga sangat riskan untuk jatuh.
Bila kedalaman permukaan sumber air anda lebih dari 9 meter, maka anda sebaiknya menggunakan pompa air berjenis jet pump. Dengan menggunakan pompa air jenis ini, maka sumur minimal harus memiliki diameter 4″, agar ventury jet dapat masuk ke dalam sumur. Berbeda dengan pompa sumur dangkal dan semi jet pump, pada pompa jenis ini, watt yang lebih besar memiliki daya hisap yang lebih dalam pula. Tetapi tetap saja informasi spesifikasi pompa dari produsen tidak dapat menjadi patokan anda dalam menentukan pompa dengan berdaya listrik yang tepat.
Untuk kedalaman permukaan air hingga 12 meter, anda dapat menggunakan pompa jet pump berdaya listrik 125 Watt atau 150 Watt. Pompa jet pump berdaya listrik kecil ini, saat ini termasuk yang sulit ditemukan di pasaran dan hanya diproduksi oleh 2 merk, yaitu merk Panasonic (GN-125H, 125 Watt) dan Shimuzu (PC150 BIT, 150 Watt). Pada informasi spesfikasi produk dari produsen pompa jenis ini umumnya disebut memiliki daya hisap hingga 15 meter. Untuk kedalaman permukaan air lebih dari 12 meter ada patokan standar yang umumnya sudah diketahui oleh toko atau tukang pompa, yaitu : 15 meter adalah kedalaman maksimal yang optimal untuk pompa jet pump 250 Watt atau 300 Watt, 18 meter untuk yang berdaya 375 Watt, dan 20 meter untuk yang berdaya 500 Watt. Lebih dari patokan tersebut umumnya kapasitas air yang keluar dari pompa air sudah tidak optimal untuk penggunaan rumah tangga yang sederhana sekali pun. Jangan terkecoh dengan informasi spesifikasi daya hisap dari produsen, yang umumnya mencantumkan 30 meter untuk pompa jet pump berdaya 250 Watt atau 300 Watt, 40 meter untuk berdaya 375 Watt, dan 50 meter untuk berdaya 500 Watt.
Standard atau patokan di atas dapat dikatakan sama untuk semua merk, sehingga pompa air berdaya sama tetapi berharga lebih mahal, tidak berarti memiliki daya hisap yang lebih baik. Perbedaan harga pada masing-masing merk, lebih pada kualitas dari lilitan motor, yang mempengaruhi panjang pendek umur pompa, kualitas bahan body, komponen motor dan elektronik dan juga layanan purna jualnya.
Bila kedalaman permukaan air anda sudah melebih 20 meter, anda sudah sangat disarankan untuk menggunakan pompa air berjenis submersible. Untuk jenis-jenis pompa submersible yang sesuai berdasarkan permukaan airnya, akan kami jelaskan di lain waktu.
Informasi lainnya adalah hingga ketinggian berapa, air akan disalurkan. Daya dorong juga dipengaruhi oleh berapa kedalaman hisapnya. Makin pendek daya hisap, makin jauh daya dorongnya. Bila menggunakan pompa jet pump atau semi jet dengan daya hisap optimal sesuai dengan standar di atas, sebaiknya anda menggunakan penampungan air yang dekat dengan pompa. Sehingga anda perlu menggunakan 2 pompa, satu pompa untuk menghisap dari sumur, satu pompa lagi untuk menghisap dari penampungan ke penampungan di atas atau untuk langsung di pakai. Kecuali anda menggunakan pompa tersebut hanya untuk keperluan satu lantai dengan 1 hingga 2 titik air saja.
Informasi lain yang perlu diketahui adalah berapa kapasitas daya listrik rumah anda, karena daya listrik pompa pada saat start selalu 2 kali daya listrik normalnya. Sebagai contoh, pompa air sumur dangkal berdaya listrik 125 watt, pada saat start memerlukan daya listrik 250 watt. Bila rumah anda hanya memiliki daya listrik 450 watt, anda tidak dapat menggunakan pompa jet pump atau pompa semi jet pump berdaya 250 Watt ke atas. Bila rumah anda berdaya 900 watt, anda dapat menggunakan jet pump hingga 375 Watt, tetapi mungkin perlu dipertimbangkan untuk meningkatkan daya listrik anda 1300 watt, karena bila digabung dengan perangkat listrik dan elektronik lainnya bisa jadi kurang. Yang perlu diperhatikan bila anda memilih menggunakan pompa jet pump berdaya 500 watt. Karena khusus untuk tipe ini daya listrik yang diperlukan pada saat start adalah 3 kali daya normal, sehingga menjadi 1500 watt. Oleh karena itu untuk dapat menggunakan pompa ini, kapasitas daya listrik di rumah anda minimal sudah berdaya 2200 watt. Ada beberapa merk yang pompanya tetap hidup walaupun daya listrik anda 1300 watt, tetapi umumnya daya hisapnya menjadi jauh berkurang, sehingga kami tetap menyarankan anda memiliki kapasitas daya listrik 2200 watt.
Informasi terakhir yang anda butuhkan tentunya adalah budget anda. Karena ini mempengaruhi merk apa yang akan beli. Perlu kami tekankan sekali lagi standard daya hisap di atas, dapat dikatakan sama untuk semua merk, baik itu merk kelas termurah seperti Pompe, Airlux, dan lain-lain , merk menengah seperti Shimizu, Wasser, Panasonic, DAB, DABAQUA, Multipro, dan lain-lain, bahkan merk kelas atas seperti Grundfos, Pentax, Pedrolo, Sanyo, Hitachi. Sehingga memilih merk yang sesuai tergantung dari budget dan juga preferensi merk yang anda miliki.
Semoga informasi ini dapat membantu anda untuk memilih pompa air yang tepat. Sekali lagi selamat berbelanja!

Kontrak Dengan Iblis
Awalnya adalah dua lelaki pemalu Mereka puritan “mengapa mesin pencari meski dijejeli dengan iklan ? “ Tanya dua kandidat doktor dari Standford university Larry Page dan Sergey Bri, Pendiri Google.
Google melahirkan mesin pencari yang berbeda. Saat Google dilahirkan dunia berteriak kaget. Mereka menahan nafas seluruh dunia terguncang takjub akan kecepatan mesin pencari Google hasil pencariannya pun jarang meleset ia pun hadir bersih dari iklan. Siapa sangka Google menyapu semua raja internet kala itu? Pada tahun 1998, orang percaya raja internet adalah yahoo!! Ada juga yang berpikir mahkota raja itu akan jatuh pada raja raja mesin pencari saat itu. Ada Alta Vista, Ask jeeves, HotBot, Excite, Infoseek, dan Nothern Light.
Faktanya mereka semua tenggelam nafsu memburu iklan jangka pendek kalah dengan visi “bersih Iklan” ala Google teknologi pencarian mereka yang kuno, yang disebut MetaCrawler, juga membuat mereka tak bias bersaing hasil pencarian sering salah juga lama. bahkan secuil coklat sudah habis dikunyah tapi kadang hasil pencariannya belum nongol.
Google lahir pada 1998 dan seluruh dunia tercengang. Siapa saat ini yang tidak ter-Google? Mencari berita lewat Google. Bertemu dengan penjual ponsel juga lewat Google mencari peta kondangan lewat Google Map mengintip buku cara memelihara ikan koi juga lewat Google Book Search membikin info grafis kecelakaan pesawat juga dengan Google Earth sok pintar menulis status di Facebook dengan bahasa Cina juga dengan bantuan Google Translate mengenang band Jadul lewat “youtube” milik Google nyaris seluruh denyut kehidupan ini dilayani Google. Walaupun sudah menguasai separuh nafas kehidupan toh Google tetap berlagak santun mereka Cuma memasang Iklan tiga baris bukan iklan banner besar besaran.
“Don’t be evil” begitu pendapat Google jangan serakah jangan mengorbankan kenyamanan demi iklan jangka pendek begitu pesan yang ditanamkan jadi jangan heran walau youtube diakses ratusan juta orang tak banyak iklan di sana
Toh kendati Cuma iklan aris kini banyak orang gusar, Rupert Murdoch konglomerat media contohnya, dia mengancam akan memblokir akses Google ke situs situs berita miliknya. Murdoch menguasai Koran Koran penting di Australia, Inggris dan Amerika Serikat, salah satunya Wall Street journal.
Mengapa Murdoch gusar terhadap iklan baris Google? Google pada tahun 2008 meraup pendapatan USS 21.8 miliar. Sedangkan yang empunya berita-situs Koran- justru megap megap. Nilai saham nya mencapai USS 132 miliar bayangkan, setara degan APBN Indonesia dalam setahun.
Dengan kekayaan itu Google yang puritan super- agresif. Dia seperti vacuum cleaner menyedot apa saja, dengan enteng dia membeli Youtube seharga USS 1,65 milyar mereka juga membeli AdMob biro iklan untuk internet di ponsel.
Dengan ukuran serakasasa itu mereka bias mencaplok apa saja” kata Ivan Seindenberg CEO Verizon.
Saking agresifnya mereka siap melawan Facebook, Twitter, atau kongsi yahoo!-Microsoft entah bercanda atau serius, Sergey Brin Sampai berkata “biskah anda membikinkan saya kontrak,Saya perlu membuat kontrak kerjasama dengan Iblis.
