Huzur icinde yat buyuk adam!
This is a prepared text of the Commencement address delivered by Steve Jobs, CEO of Apple Computer and of Pixar Animation Studios, on June 12, 2005.
I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I’ve ever gotten to a college graduation. Today I want to tell you three stories from my life. That’s it. No big deal. Just three stories.
The first story is about connecting the dots.
I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out? It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: “We have an unexpected baby boy; do you want him?” They said: “Of course.” My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college. And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents’ savings were being spent on my college tuition. After six months, I couldn’t see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn’t interest me, and begin dropping in on the ones that looked interesting. It wasn’t all romantic. I didn’t have a dorm room, so I slept on the floor in friends’ rooms, I returned coke bottles for the 5¢ deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example: Reed College at that time offered perhaps the best calligraphy instruction in the country. Throughout the campus every poster, every label on every drawer, was beautifully hand calligraphed. Because I had dropped out and didn’t have to take the normal classes, I decided to take a calligraphy class to learn how to do this. I learned about serif and san serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can’t capture, and I found it fascinating. None of this had even a hope of any practical application in my life. But ten years later, when we were designing the first Macintosh computer, it all came back to me. And we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, it’s likely that no personal computer would have them. If I had never dropped out, I would have never dropped in on this calligraphy class, and personal computers might not have the wonderful typography that they do. Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backwards ten years later. Again, you can’t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
My second story is about love and loss.
I was lucky — I found what I loved to do early in life. Woz and I started Apple in my parents garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4000 employees. We had just released our finest creation — the Macintosh — a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started? Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge and eventually we had a falling out. When we did, our Board of Directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was devastating. I really didn’t know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down – that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure, and I even thought about running away from the valley. But something slowly began to dawn on me — I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over. I didn’t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life. During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the worlds first computer animated feature film, Toy Story, and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I returned to Apple, and the technology we developed at NeXT is at the heart of Apple’s current renaissance. And Laurene and I have a wonderful family together. I’m pretty sure none of this would have happened if I hadn’t been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don’t lose faith. I’m convinced that the only thing that kept me going was that I loved what I did. You’ve got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don’t settle.
My third story is about death.
When I was 17, I read a quote that went something like: “If you live each day as if it was your last, someday you’ll most certainly be right.” It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: “If today were the last day of my life, would I want to do what I am about to do today?” And whenever the answer has been “No” for too many days in a row, I know I need to change something. Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure – these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart. About a year ago I was diagnosed with cancer. I had a scan at 7:30 in the morning, and it clearly showed a tumor on my pancreas. I didn’t even know what a pancreas was. The doctors told me this was almost certainly a type of cancer that is incurable, and that I should expect to live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is doctor’s code for prepare to die. It means to try to tell your kids everything you thought you’d have the next 10 years to tell them in just a few months. It means to make sure everything is buttoned up so that it will be as easy as possible for your family. It means to say your goodbyes. I lived with that diagnosis all day. Later that evening I had a biopsy, where they stuck an endoscope down my throat, through my stomach and into my intestines, put a needle into my pancreas and got a few cells from the tumor. I was sedated, but my wife, who was there, told me that when they viewed the cells under a microscope the doctors started crying because it turned out to be a very rare form of pancreatic cancer that is curable with surgery. I had the surgery and I’m fine now.
This was the closest I’ve been to facing death, and I hope it’s the closest I get for a few more decades. Having lived through it, I can now say this to you with a bit more certainty than when death was a useful but purely intellectual concept: No one wants to die. Even people who want to go to heaven don’t want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life’s change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true. Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma — which is living with the results of other people’s thinking. Don’t let the noise of others’ opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary. When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of the bibles of my generation. It was created by a fellow named Stewart Brand not far from here in Menlo Park, and he brought it to life with his poetic touch. This was in the late 1960’s, before personal computers and desktop publishing, so it was all made with typewriters, scissors, and polaroid cameras. It was sort of like Google in paperback form, 35 years before Google came along: it was idealistic, and overflowing with neat tools and great notions. Stewart and his team put out several issues of The Whole Earth Catalog, and then when it had run its course, they put out a final issue. It was the mid-1970s, and I was your age. On the back cover of their final issue was a photograph of an early morning country road, the kind you might find yourself hitchhiking on if you were so adventurous. Beneath it were the words: “Stay Hungry. Stay Foolish.” It was their farewell message as they signed off. Stay Hungry. Stay Foolish. And I have always wished that for myself. And now, as you graduate to begin anew, I wish that for you. Stay Hungry. Stay Foolish. Thank you all very much….”
Apple ‘in time machine uygulamasi muhtesem bir olay. Eger time capsule, yada bir harici USB Disk, yada diskin ikinci bolumune yedekleme yap diye emir vermisseniz; siztem sizin yerinize otomatik olarak;
1. Son 1 gun icersinde saatlik
2. Son 1 ay icerisinde gunluk
3. Geriye kalan zamanda hard disk dolana kadar haftalik yedek almaya devam eder.
Bu guzel uygulama sayesinde yuklu olan programlarimdan kendi sistem ayarlarima kadar olan herseyimi yeni sistem kurulumuna rahatca geri yukledim. Ama bugunlerde sistem yedekleme ile ilgili olarak sistemin yedeginin almasinin birazda kotu bir tarafi oldugunun kesfettim. Eger onemli bir is uzerinde calisiyorsaniz ve sistem kaynaklarini kullanmaya ihtiyaciniz varsa. Time capsule sizin ne is yaptiginiza bakmadan her saat basi gelerek yedekleme islemini baslatiyor ve sisteminizde ciddi bir yavaslama hissediyorsunuz. Sistem yedekleme zamanini degistirebilirmiyim diye arastirirken ontanimli arayuzde boyle bir secenek olmadigini gordum. Fakat biz yedekleme zamanini elle yada bir program vasitasi ile degistirebiliriz.
1. Komut satirindan yazarak;
Asagidaki sekilde istedigimiz yedekleme suresini saniye cinsinden komut satirina girerek istedigimiz sekilde yedekleme zamanini ayarlayabiliriz. Burada 18000 sn (5 saat) de bir yedekleme yapmasini istedim.
sudo defaults write /System/Library/LaunchDaemons/com.apple.backupd-auto StartInterval -int 18000
2. Dosyadan editleyerek;
/System/Library/LaunchDaemons/ dizinine giderek “com.apple.backupd-auto” dosyasini aciniz ve 3600 degeri istediniz deger ile degistirerek kayderek cikiniz.
<key>StartInterval</key> <integer>3600</integer>3. Time Machine Scheduleler ile;
Stefan Klieme ‘nin yazmis oldugu time machine schedule yazilim programi ile kac saatte bir yedekleme alinmasi gerektigini belirleyebilirsiniz veya belirlediginiz zaman aralagini yedekleme zamani disinda birakabilirsiniz.
http://www.klieme.com/TimeMachineScheduler.html adresinden programi indirip kurmak yeterlidir.
Bugun sistem yonetecileri icin hatirlanma gunu, 12 yil once baslayan bu etkinlik Her yil temmuz ayinin son haftasinin Cuma gunu gerceklesmektedir.
Bircok insanin farkinda olmadigi fakat digital dunyanin kesintisiz ve dogru bir sekilde calismasini saglayan sistem yoneticilerini genelde ne zaman basimiz sikissa arariz. Halbuki gezdigimiz sayfalar, parolalar, aldigimiz ciktilar, digital hayatla olan bildiginiz tum bilgiler aslinda onlar tarafindan bilinir ve korunur. Bir dusunun sizinle ilgili neler bilebilirler. 
En guzeli bugun bir sistem yoneticisini sevindirin, oda sizi sevindirsin.
There’s a guy who works in another room,
Or, on another floor.
He’s the one you call,
When your document ain’t there no more.
He’s probably a boy, but he might be a girl,
Or, something in-between.
He’s the only one in the building
Who knows what PC load-letter means.
He’s your System Administrator.
He probably reads comic books.
And you tremble in fear when you have to hear one of his,
“What a dummy”, looks.
Got a virus, lost your password or you just can’t print?
In an hour he’ll show and then he’ll crouch and squint.
Fight to save your files, he might be there all day.
But sometimes, he just presses caps lock…and he walks away…
But hey! Suddenly my password works! Hooray!
Hooray, happy Syst. Admin. day,
Gonna buy my guy a gift to say:
“Having you around means I get to stay
Stupid! And uninformed!”
And I can keep opening .exe e-mail attachments,
And forgetting my mother’s maiden name,
And naming files with spaces
And ampersands and colons,
‘Cause you’ll fix it all for me!
I’ll give you a cake,
I’ll give you a hug,
I’ll buy “The World’s Best
System Administrator” mug,
Just help me out…
System Administrator!
Delete my Recently Viewed Websites file!
(Administrator)
Restore my network settings so I can find my F drive!
(Administrator)
Argh! Plug in my mouse!
(Administrator)
Piss him off,
And you’ll be fired by tomorrow morn,
Cause he’s the guy
Who knows that you were surfing porn.
So July 26th….
Make sure you get a present for your…
System….Ad-min-is-traaa-torrr.
Mac kullanmaya basladiktan sonra isletim sistemi bana yedeklerini al. “Bak xxx gun gecti hala yedeklemedin” diye mirildanmaya baslamisti. Bende zaten elle yedekleme yapiyorum sana ne diye ihtiyacim var diye diye dusunurken. Hadi len seni mi kiracam al iste sana 500Gb tasinabilir Disk istedigin gibi yedekle diyerek “Apple Time Machine” uygulamasini kullanmaya baladim.
Aradan bir yil gecti ve 250Gb lik hard diskimi 500Gb (Bkz. Niyet 1TB ama biryerde patlayinca mecburen bunu almak zorunda kaldik) yukseltirken iyi ki otomatik olarak yedekleme islemini baslattigimin farkina vardim. 35dk isletim sistemi kurulumu 75 dk sistem geri yuklemesinden sonra kullanmis oldugum tum programlar, ayarlari ile birlikte geri yuklendi. Arsivden 2010 senesinde masa ustumdeki dosyalarin var olup olmadigini kontrol ettim hepsi yerinde. coktan silmis olsam bile “Time Machine” benim yerime sakliyor. Insan boylelikle kendini biraz olsun guvende hissediyor ama bir yandan da dususunmeden edemiyor?
“Iyi guzelde bilgisayarimdakilerin hepsi yedekli ya cantam calinirsa? O zaman hem mac hemde yedekler gidecek. Ben ne anladim bu isten?” dememek icin “Time Capsule” almaya karar verdim. Evde hem wireless Access Point hem laptop acik kaldiginda otomatik yedekleme ozelligi ile gunluk yedekleme islemim kendiliginden yapilmis olacak.
Not: Mac kurulumu ve yedekleme sonrasinda sadece kisisel dosyalar, programlar yada siz neyi yedekle dediyseniz o geri yukleniyor. Malesef guncellemeleri yeniden yuklemek durumundasiniz. Yada bende bu sekildeydi. Mac OS X 10.6 kurulumundan sonra 10.6.8′e guncellemek bayaa zaman aliyormus.
Unix dunyasi 26 Haziran sabah uzucu bir haber ile uyandi: Unix’in olusturulmasinda buyuk katkisi olmus kripto uzmani Robert Morris 78 yasinda hayata veda etti. Morris 1970′lerde AT&T Bell Laboratuatlarinda OS’nin gelistirilmesinde mucit olarak baslamistir. Ozellikle Unix;in mathematik kutuphanelerinin gelistirilmesinde ana gorevde bulunmus, parola yapisi ve kriptolama fonksiyonlarinin gelistirilmesini saglamistir. Once Almanya’da kriptolama uzerine kagit uzerindeki calismalari 1970lerin sonuna kadar etmistir. Olasi guvenlik endiseleri dolayisiyla, NSA talebi sonrasinda, bu kagitlar asla gun yuzunu gormemistir. Bunun yerine, ajans 1986 yılında bir bilgisayar güvenlik uzmanı olarak Morris’i goreve getirmistir. Onun Sam amca icin yaptiklari cogu zaman gizli kalmistir, dusunun internet izleme projesi ve siber savasi icat etmis, buna birinci korfez savasi sirasinda Saddam Huseyin’in kontrol yeteneklerini devre disi birakmak icin Amerika’nin 1991 deki siber saldirisi dahil olabilir. Morris 1994 yilina kadar NSA’de kaldi ve sonra New Hampshire’e yerlesti.
Geride bir kocaman dijital parmak izi birakarak bize 26 Haziran 2011′de veda etti.

Aslinda hersey iyi niyet ile basladi. Zaten insan kendi kendine neden zarar versin ki? Biraz can sikintisindan birazda 2011 IT yatirimlarim planlarimi hayata gecirmek icin 250GB olan Hard Diskimi yukseltmeye karar verdim. Gittim Bakinity magzasina kendime soyle 1TB 2.5″ notebook disk aldim. Ama alirken de aklimda vardi simdi ben bu isi yapiyorum ama Mac oyle her hard diski kabul edermi maksimum disk ne olmali vs vs … Magazadaki calisan ucretsiz montaj yapilacagi ve sorunla karsilasilirsa baska urun verilecegini soyleyince biraz rahatladim.
Aldim diski gittim yan taraftaki teknik servise montaji yaptilar. Yaninda disk varmi? Yok! Nasil test edecez? Ben evde yuklerim deyip ciktim. Gunlerden Cumartesi saat 18.00
Evde diski taktim, basladim kurmaya… Kurulum gitti gitti kaldi. Haydaa? Ac installer.log ‘u incele dur. Eee her sey iyi gitmis ama /Volumes ten sonra ilerlemiyor. Trink! Acaba 1Tb alipta abarttik mi? Neyse bir deneme daha. Olmadi. Belki Mac OS X 10.6 Snow Leopard ciktiginda desteklemiyordur belki onumuzdeki ay cikacak olan 10.7 Lion destekler. Gece ayarla bir laptop ve torrent sitesinden Mac OS X 10.7 Developer Review 4 bul sabaha inmesini bekle. Umut bu ya; 10.7 de destekleyecek!
Pazar sabahi yeni gun ustelik Developer Review 4 var. Olacak bu is! Kurulum basladi, Gayet hizli bir sekilde ilerliyor. 10.6 dan %30-40 daha hizli. Gozler artik installer.log penceresinde /Volumes gecti, Ohhhh /Volumes/Bilmem_ne Ohhh… Derken gene durdu. Bekle bekle …. 1 tane log yok. Ne hata nede baska birsey. 1 saat beklemeden sonra durum anlasildi. Bir b.k yedik nasil temizleyecez???
P.tesi gunu oglen Apple Store Technical Servisteyim. HDD yukselttim ama calismadi? –Ne yaptiniz? 1TB aldim. –Alirken sordunuz mu? Evet –Peki ne kadar’a kadar destekleniyor biliyormusunuz? Hayir –750Gb sonrasini Apple desteklemez. Eee ben yenisini alsam siz takar misiniz? Tabii 20Euro kurulum 50Euro. (Ne kadar guzel, buda kasinmanin yan etkileri) Git Bakinitiy’e ver 1′i al yarimi.
Velhasil ben garanti olsun diye 500GB slim HDD aldim. Diski taktilar 20Euro’yu aldilar. Sonrasi malum, evde kurulum + restore from backup.
Simdi hersey yolunda 500Gb canavar gibi calisiyor. Sistem guncel, programlar yerinde ama kayip 2 gun? Bilgisayarsiz gecen 48 saat? Gec yazilan rapor? Iste tam niyazilik bir durum.
Son olarak, ODTU’de iken Bilgi Islem Daire Baskanliginda Ozan diye arkadasim vardi. Saolsun Debian ve Linux konusunda Gokhan Eryol ile birlikte benim gelisme cok buyuk katkisi olmustur. O bir ise baslamadan once daima su sozu hatirlatirdi. “Read The Manual First.” Hata yapmamak icin once;
READ THE F***ING MANUAL!
Bu basit bir ipucudur ama bir o kadar da onemlidir: ne zaman Debian isletim sistemini yuklemek istesek, makinenin kablo ile internete bagli olduguna emin olmak durumun da kaliriz.
Cevabi aslinda basit, cunku Squeeze de ki debian-installer sadece WEP desteklemekte WPA sifreleme sistemini henuz desteklememektedir. Eger siz WPA kullaniyorsaniz kurulum sirasinda kablosuz baglantiyi kullanamayacak ve gereken paketleri alamayacaksiniz. Bu sebeple WPA baglantisi olan yerlerde kablolu kurulumlari tercih ediniz.
Tabii eger hala siz WEP sifrelemesi kullaniyorsaniz, Kablosuz kuruluma devam edebilirsiniz.
Eger yalnizca kablosuz ag baglantiniz var ve bu baglanti WPA sifrelemesine sahipse, bu durumda debian-insteller team den yardim talep edebilirsiniz. Matthew Palmer birkac ay once bazi calismalarda bulunmustu ( bu emailde ve onun subesindeki netcfg git deposunu ve calismalarini bulabilirsiniz) Matthew debian-installer takimindan istifa etti ve sonuc olarak WPA destegi hala wheezy debian-installer da mevcut degildir.
apt-get install desem ilk baslangic diskini aramadan en guncel sekilde calismasidir.Mac OS X Lion yeni sozlukler ve gelismis bircok bolmesi arabirimi ile birlikte yen arayuz cercevesinde yeni lehceler icermektedir. Sistem ayni zamanda genel olarak gelismis Spotlight entagrasyonu ve metin ici aramalari icin multi-touch destegi ile sozlugu gelistirmistir.
Yeni referans dosyalari
Mac OS X Lion guncellemesinde yer alan sozluk uygulamasi halen var olan New Oxford American English” sozlugunun 2010 ucuncu surumunu icermektedir. (Su anda bizim kulalndigimiz 2005deki ikinci surumdur)
Yeni sozluge “Oxford Dictionary of [British] English” eklenmistir, bu sozlukte 2010 ucuncu surumu icermektedir, ve British English Thesaurus da American English surumune eklenmistir.
The Japanese, Japanese-English, ve Japanese sinonim sozlukleri guncellenmistir., Apple ayni anda kendi sozluk dosyalarinida sirketin ticari markasi ve urun isimleri de dahil olmak uzere guncellenmistir.
Daha iyi uygulama, Sistem entegrasyonu
Uygulamanin simdi iki tane cercevesi vardir, boylelikle daha kolay referans kelimelere, esanlamlilara veya wikipedia aramalarina alfabetik sirada bakilabilir, Mevcut surumde sadece bir cervede 1 tane kelime veya sozcuk gosterimi yapilmaktadir.
Ilaveten, Spotlight’ta sadece birkac kelimenin gosterildigi pencere yerine simdi pop-up pencere acilmaktadir ve kelimler tam onzilemeli olarak gorulebilmektedir.
Son olarak, secilen kelimenin uzerinde uc parmak ile cift tiklayarak herhangi bir standart uygulamada metin ici sozlugu getirmistir, daha onceleri menuden “Look Up In Dictionary”‘yi secmek durumundaydik. Sozcuk icerisinde bir tercihi menu komutu; inline mini sozlugu veya tam sozluk uygulamasini baslatabilir.
