Text of Steve Jobs' Commencement address (2005)

http://news.stanford.edu/news/2005/june15/jobs-061505.html



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.

Canonical Releases Windows Version of Ubuntu One

http://techcrunch.com/2011/09/30/canonical-releases-windows-version-of-ubuntu-one/
 | TechCrunch


Canonical, the commercial backer behind theUbuntu Linux distribution, have been hosting a file synchronization service called Ubuntu Onefor a couple years now. A free account gets you 5GB of storage, and the client side controls have been baked into the last couple of releases of the Ubuntu distribution. It works pretty much like Dropbox or similar services, but has been — until today — Linux-only.
In an announcement late last night, Canonical has revealed that there is now a Windows client for Ubuntu One, allowing you to access all your files from either Linux or Windows computers.
We have long received feedback from Ubuntu users regarding their evolving needs to manage all their content from a single, secure place across multiple platforms and devices. We've looked at many use cases, the most common being the Ubuntu user who is using more than one device or OS. Many people have to work in Windows or Mac environments, even if they prefer to use Ubuntu as their home desktop or OS of choice. Another case is enabling more opportunities for sharing across platforms. For example families using different operating systems in one household can use Ubuntu One as their central place to store all their music, documents, photos and share them easily with each other and friends.
Ubuntu One also offers a nifty music streaming service. For $4 per month, you get 20 GB of storage and the ability to stream music files from your account to your mobile device. The Ubuntu One app is available for iOS and Android, and Android devices get the added benefit of a controllable offline cache, allowing you to listen to your cloud-stored music without requiring a network connection. Neat stuff.

Creating realistic HDRs

http://www.pixiq.com/article/creating-realistic-hdrs
 | Pixiq


Multiple exposures is what can help in such situations: I usually take multiple exposures shifting 2Ev step for each, capturing the darkest areas (going + on Ev compensation) to a brightest ( + Ev compensation). Then the sequence of the image can be combined into a single file using special software like Photomatix or a "regular" Photoshop CS will do a job.


Few words about how I shoot HDR:
In most cases I shoot in manual mode, this allows me to do as many Ev bracketing shots as needed: 3, 5 or even 7. What I am getting is a ultra wide dynamic range of 14Ev or more.
An example of such 14Ev DR shot is below. Deep shadows and bright noon sun required such wide DR to get the image I like:

美国教育: 高科技设备

http://www.usa101.cn/edu/edu004.asp


 华盛顿报导
维吉尼亚州阿灵顿县跟美国首都华盛顿仅一河之隔,这个地处维州郊区的社区面积不大,但是人口稠密。该县公立学校学生人数超过1万8千人,学生来自127个国家,讲100多种语言。

阿灵顿县公立学校大约三分之一的学生来自低收入家庭,他们享受学校的免费或者减价午餐,但同时阿灵顿县又是非常富有,他们刚刚斥资9500万美元建造了一所现代化高中。

这所学校里有不少电脑,这并不稀奇,让人感到意外的是,学校用一种高科技、多用途的显示装置代替了每间教室的传统黑板。

华盛顿-李高中科技协调人桑迪·芒内尔说:"这种产品叫做智能板,是一种交互式白板。老师站在白板前面,通过触摸控制电脑。老师可以用这种奇妙的办法跟全班同学共用一台电脑。"

芒内尔讲解智能板各种功能时颇费了一些工夫,因为它能做的事情可真不少。智能板看上去跟墙上的普通白墙没什么两样,但是它的表面是触摸式的,在智能板的顶部,探出一根操纵杆,外端装有一台视频投影机。

学校小型电视演播室播出的早间通知可以通过教室的智能板让学生看到。你可以在万维网上浏览,用一种特制的电子笔把网页的某个部分重点画出来。这种特制电子笔外加一个书写识别软件之后,还可以跟粉笔一样写字。
生物老师杰森·布罗多夫斯基借助智能板向学生讲述如何使用显微镜。

布罗多夫斯基说:"只需把显微镜跟数码照相机连接上,就能在智能板上显示,这样全班就能看到显微镜工作的全部过程。这样一旦我把图像聚焦之后,学生们就会说,噢,我知道你刚才讲得是什么了。接着,他们可以操作自己的显微镜,亲自做试验。这样就有趣多了。"

华盛顿-李高中有差不多600台电脑供学生们使用,相当于每三个学生至少有一台电脑。整个教学楼有好几个电脑机房,宽敞、明亮的图书馆不仅有图书,还配备了电脑。

华盛顿-李高中订阅在线参考书,这些参考书频繁更新。学生们在校外也可以上网使用这些网上参考书。

互联网上有大量有价值的资料,但是也有不少内容不适宜青少年。因此,学校安装了软件,专门封锁以色情等内容为特色的网站。不过,图书管理员林内特·康斯坦丁内兹认为,阿灵顿县公立学校学生的多元化,使得学校难以保护青少年免受互联网不良影响。

康斯坦丁内兹说:"学校可能有学生来自蒙古,不错,阿灵顿这个地方来自蒙古的人口虽然不多,但是却不容忽视。来自中东的移民也属于这种情况。我们在他们后面,看着他们登上他们母语的网站,但是根本不知道他们在干些什么。"

那么,学校的网络过滤器能否过滤乌尔都语或者普什图语吗?
康斯坦丁内兹说,"不能。即使是过滤英语网站过滤器也不特别管用。"

华盛顿-李高中图书馆放学后还要继续开放两、三个小时。来自伊朗移民家庭的学生萨翰德·米纳耶正利用这几个小时,在图书馆的电脑上网。

他说:"我在为吉他班在网上找乐谱。我想为吉他班找到几首乐谱,为我们在网络咖啡馆演奏做准备。我们在所有的网站上搜索,尽量多搜集些古典音乐、民间音乐和现代音乐。"

楼下的网络咖啡馆有28台电脑,那里舒适、诱人,但不卖咖啡。科技协调人桑迪·芒内尔说,开设这个网吧主要是方便学生,特别是家里没有电脑的学生使用电脑。

他说:"阿灵顿县对这个网吧投入了大量资金,尽可能让它舒适,因为我们知道,信息技术带来了经济鸿沟,我们要缩小这个差距。在学生正常上课时间,整个教学楼有许多电脑可供使用,可是放学后学生们上网的机会就没有那么多了。"

芒内尔说,即使他们使用了所有的最新科技,仍然不能保证这个新的现代化教学楼不会过时。华盛顿-李高中目前大容量的线缆还可以再使用几年,但是未来几代学生很可能会无线上网。
