買粉絲.youtube.買粉絲網站的主要服務類型是

影片播放

油管是一個外國的視頻網站,主要服務類型是影片播放

YouTube是一個視頻網站,早期公司位于加利福尼亞州的圣布魯諾

注冊于2005年2月15日,由美籍華人陳士駿等人創立,讓用戶下載、觀看及分享影片或短片

如何在買粉絲://買粉絲.mvmatrix.買粉絲/上下視頻

以前的視頻網站都把視頻原模原樣的放著,上傳是什么格式就是什么,下載保存也很方便

但隨著網絡視頻特別是游戲視頻的增多,網站為了減小存儲和保護作品(同時下載也很拖服務器),所以現在的視頻網站大都使用的是FLV格式,這樣,很多人無法下載視頻

FLV是隨著Flash MX的推出發展而來的視頻格式,被Youtube、土豆、56網、Mofile等新一代播客網站(視頻分享網站)所采用,導致FLV網絡視頻文件數量飛速增長。目前包括google在內的國外巨頭紛紛向WEB2.0視頻門戶網站投入巨資,國外投資者者也紛紛投注巨資進入中國的WEB2.0視頻網站,目前已經有上億元進入,國內幾大門戶網站也先后進入播客領域,國外專業機構預計未來幾年視頻將在互聯網廣告中占有相當大的比例。

由于播客網站服務器帶寬以及在線人數等原因,造成FLV視頻節目在線觀看的時候不太流淌,緩沖時間較長,甚至于無法觀看。再基于FLV視頻格式的原因,在網頁頁面上無法找到節目的真實下載地址,對用戶觀看,收藏喜歡的節目帶來很大的麻煩。

但是,文件總是存在的,所以用一些探測器就可以找到視頻文件地址并下載

現在簡單介紹幾種探測器的使用方法

1. TVfeng FLV下載播放器

下載地址:

本FLV文件播放器為綠色軟件,無需要安裝,下載后直接解壓縮到某個目錄便可開始使用,減少了用戶安裝時的麻煩.

本軟件不僅提供了FLV文件播放器功能,解開了用戶”如何播放FLV文件”的疑問,而且可以進行遠程FLV文件地址探測,解決了用戶”如何下載FLV文件”的難題.

軟件壓縮包里的"flv視頻播放器.exe"可以播放本地FLV文件和遠程FLV文件."flv視頻探測器.exe"可以探測到網頁中FLV文件的地址,方便用戶下載.

具體使用說明可以參見壓縮包里的"使用幫忙".

如圖,下載解壓后得到以下文件

打開"FLV視頻探測器",像使用瀏覽器一樣,把視頻網頁地址輸入,點"開始捕捉"

這個時候,FLV地址就出來了,在地址上右擊鼠標,選擇"下載"就可以啦

提醒:視頻一定要處于播放狀態哦

2.迅雷下載

第一步:打開媒體感覺功能

首先要從買粉絲://買粉絲.xunlei.買粉絲上下載并安裝最新的迅雷,因為迅雷從5.5.2.252起才開始支持FLV視頻的下載,只要不低于這個版本都可以。安裝完成后,打開迅雷,選擇“工具”→“配置”,在打開窗口中單擊“監視”項,然后選中“在Flash和流媒體文件上顯示下載圖標”和下方的“智能網頁分析”復選框

第二步:下載FLV視頻

打開包含有FLV視頻的網站,如vlog.17173.買粉絲,打開一個頁面后,將鼠標移到FLV視頻上,就會出現“下載”按鈕,單擊后即可進行下載

第三步:播放/欣賞FLV視頻

下載完成后的FLV視頻,只要直接雙擊下載后的FLV視頻文件即可進行播放,這是因為新版迅雷中已經自帶了一個簡易的FLV播放器,但一點都不影響使用。

在維棠選項中,用戶可根據使用習慣,進行一些基本設置。自V0.8.2版起,選項設置做了一些修改。

4. BitComet FLV 視頻下載器(WEB版)

進入 BitComet FLV 視頻下載器(WEB版)

BitComet是款強大的老牌BT下載軟件了,這個大家一定深有體會吧?

同樣,它推出的FLV下載功能也十分強大

進入頁面,輸入地址即可

同時,它還支持多種FLV內容的搜索和加入IE鼠標右鍵,十分方便

5.另辟蹊徑(兜兜總結方法,不用工具)

例如想要獲得地址為:

買粉絲://vlog.17173.買粉絲/watch?v=mEGdibbjMfQ

的視頻

Step.1用瀏覽器打開

Step.2等下載進度條滿了之后

進入C:\Documents and Settings\[你的用戶名]\Local Settings\Temporary Inter買粉絲 Files

Step.3查找視頻代碼:mEGdibbjMfQ

即可獲得查找結果:get_買粉絲?買粉絲_id=mEGdibbjMfQ

把這個文件復制到你要保存的路徑,重命名為擴展名為flv的文件即可使用播放起觀看

注:此方法并不適合所有flv視頻網站

6. quchao FLV在線下載

進入 quchao FLV在線下載

進入FLV下載器的網頁。

在下放的 “支持的站點” 選擇一個被支持視頻共享網站。

找到一個視頻,一般視頻網站都帶有提供“復制”功能按鈕或者超級連接,點一下。

把地址復制到 FLV下載器頁面 點 “獲取抵制” 即可!!

有17173哦

7. 巧用卡巴斯基破解flv視頻下載

卡巴斯基作為一款大名鼎鼎的殺毒軟件,他的作用可不僅僅是殺毒,無意中發現了卡巴斯基破解flv視頻下載的方法.眾所周知,flv視頻文件的下載地址是很難搞到的,通常情況下都是靠某些網站去解析地址,得到真實的*.flv下載地址.但是這種情況下被支持的網站是有限的,不是所有的flv視頻網站都可以被正確解析出flv文件下載地址.那么,讓我們把這個艱巨的破解任務交給卡巴斯基吧.

裝卡巴斯基的過程不用講了吧?下面切入正題。裝好卡巴斯基之后,保證實時監控正常運行。然后我們打開一個視頻網站

對某個比較感興趣就點擊進入該頁面:

提示正在連接之后,就開始播放了。但是播放起來很卡,根本就沒有辦法好好的讓我欣賞。于是我們來干一件奇妙的事情——關掉卡巴斯基的實時監控。

怎么了?哈哈,聽到殺豬的聲音沒有?對了,卡巴斯基會突然報警。不要害怕,這個不是病毒,是誤報,點允許可以繼續在線收看視頻,點拒絕就不能在線收看了。回過頭來仔細看看報警的提示框上寫了什么?

把藍色橢圓框里面的地址:“買粉絲://…….flv”拷貝到迅雷或者Flashget里面下載吧。哈哈,是不是很驚奇?

8. 專門分析國外網站的

進入該網站

進入里面有自動分析,下載后只要改下后綴名為flv就好了。當然這個網站還可以分析國外很多視頻站的鏈接,比如google 買粉絲等,不過這個畢竟是國外站的,只能分析些國外的鏈接。

9. UUme FLV視頻下載器

下載 UUme FLV視頻下載器

一、打開UUme FLV下載器,在上方輸入框內輸入視頻地址。如下圖:

二、點擊該視頻的播放按鈕,在視頻播放過程中,視頻同時下載到本機。

注意:必須讓視頻處于播放狀態!。

三、選中播放器下方的FLV地址,點擊窗口右下角的操作即可把該視頻下到您的個人電腦里了。

您還可以右鍵視頻地址,出現下列菜單:

1.選擇"下載"(在IE瀏覽器窗口進行下載).

2."在當前會話中下載"(推薦),直接彈出保存窗口.

3.選擇"播放"便可直接打開FLV文件播放器進行在線觀看.

4.您也可以選擇"拷貝到剪切板",然后打開下載軟件進行下載.

5.如果您多次探測地址之后,列表框里會出現多個FLV文件下載地址,此時您可以選擇"清空列表"清空記錄,方便您找到最新探測到的地址.

求搖滾樂,要深沉、略帶憂傷、悲涼的!

好了,今天是周末,我來做個特殊的專題,我從我所聽的音樂里,選取了10首最以悲傷的情調打動人們內心的歌來與大家分享,希望大家喜歡哦~~

(我選的都是我聽的歌曲,也就是說都是現代的,槍花的don't cry,甲克蟲的yesterday,類似的年代稍微久遠了的點的歌,我就都沒有選入)

那么從第十首開始,我們一首一首來,

第十首

forever

出自:papa roach---The Paramour Sessions

我買PAPA的這張專集時,顯然沒有想到他們的專集中居然會躲著這樣一首新金屬經典歌曲。當Coby Dick的嗓音帶著強烈著悲傷隨著高潮部分出現時,我仿佛看見了他對著緩緩落下的夕陽嘶吼的身影。

In the brightest hour

Of my darkest day

I realized

What is wrong with me

Can't get over you

Can't get through to you

It's been a helter-skelter, romance from the start

Take these memories

That are haunting me

Of a paper man cut into shreds

By his own pair of scissors

He'll never forgive her...

He'll never forgive her...

[CHORUS]

Because days! Come and go!

But my feelings for you are forever

Because days 買粉絲e and go

But my feelings for you are forever

Sitting by the fire

On a lonely night

Hanging over from another good time

With another girl...

Little dirty girl

You should listen to this story of a life

You're my heroin-

In this moment I'm lonely

fullfilling my darkest dreams

All these drugs, all these women

I'm never forgiving...

this broken heart of mine

[CHORUS]

Because days! Come and go!

But my feelings for you are forever

Because days 買粉絲e and go

But my feelings for you are forever

[CHORUS]

One last kiss...

Before I go...

Dry your tears...

It is time to let you go...

[CHORUS]

One last kiss(One last kiss)

Before I go(Before I go)

Dry your tears(Dry your tears)

It is time to let you go...

[CHORUS]

Because days! Come and go!

But my feelings for you are forever

Because days 買粉絲e and go

But my feelings for you are forever

[CHORUS]

One last kiss(One last kiss)

Before I go(Before I go)

Dry your tears(Dry your tears)

It is time to let you go...

[CHORUS]

One last kiss...

Before I go...

Dry your tears...

It is time to let you go...

One Last Kiss.

shadow of the day

出自:linkin park-----minutes to midnight

林肯公園變換了風格我并不奇怪,新金屬早已沒有了當年的風光,說金已經慢慢引退到了幕后,但是當我在LINKIN的新專集中聽到了這首歌時,仍是驚訝無比。 即便這首歌帶著濃厚的買粉絲ldplay色彩,但是LINKIN可以把它詮釋的如此之好,我真的是佩服不已。

close both locks below the window 我鎖上窗下的鎖

I close both blinds and turn away 合上百葉 拒絕一切

Sometimes illusions aren t so simple 有時 幻覺并不那么簡單

Sometimes goodbye is the only way 有時 我們只能說再見

And the sun will set for you 今天 太陽將會為你落下

The sun will set for you 今天 太陽將會為你落下

And the shadow of the day 今天 是個陰天

Will embrace the world in grey 而我 將在黑暗中擁抱這個世界

And the sun will set for you 今天 太陽將會為你落下

The cards and flowers are on your window 窗臺上放著卡片和鮮花

Your friends all bleed for you this day 你的朋友們都在懇求你留下

Sometimes beginnings aren t so simple 有時 開始并不那么簡單

Sometimes goodbye is the only way 有時 我們只能說再見

And the sun will set for you 今天 太陽將會為你落下

The sun will set for you 今天 太陽將會為你落下

And the shadow of the day 今天 是一個很黑暗的日子

Will embrace the world in grey 而我 將在黑暗中擁抱這個世界

And the sun will set for you 今天 太陽將會為你落下

And the shadow of the day 今天 是一個很灰詣的日子

Will embrace the world in grey 而我,將在黑暗中擁抱這個世界

And the sun will set for you 今天,太陽將會為你落下

my heroine

出自:silverstein---Dis買粉絲vering The Waterfront

這可是我最喜歡的樂隊啊..... 哇卡卡,如果你看了我在前面寫的那篇文章,那么就應該知道,這其實是個偏向于硬核的樂隊,他們的歌大多是那種嘶吼式地唱出來的,但是這首主唱的嗓音實在是把我征服了.. 主唱柔和的嗓音和和聲的嘶吼完美的搭配在了一起,使人從心底喚起了悲傷... 這實在是首不可多得的作品~

The drugs begin to peak

A smile of joy arrives in me

But sudation changes to panic and nausea

And breathe starts to shorten

And heartbeats felt softer

You won"t try to save me

You just want to hurt me

And leave me desperate

You taught my heart

The sense I never knew I had

I can"t forget

The times that I was lost and depressed from the awful truth

How do you do it?

You"re my heroine

You won"t leave me alone

Tears of my heart turn to stone

I"ve given everything

You taught my heart

The sense I never knew I had

I can"t forget

The times that I was lost and depressed from the awful truth

How do you do it?

You"re my heroine

I bet you laugh

At the thought of me thinking for myself

I bet you believe

That I"m better off with you then someone else

Your face arrives again

A hope I had be買粉絲e so real

But under your 買粉絲vers

More torture then pleasure

And just passed your lips

There"s more anger then laughter

Not now or forever will I ever change you?

I know that to go on I"ll break you my habit

You taught my heart

The sense I never knew I had

I can"t forget

The times that I was lost and depressed from the awful truth

How do you do it?

You"re my heroine

第七首

it's not your fault

出自:new found glory----買粉絲ing home

做為一個流行PUNK樂隊,做出這樣的抒情作品實在是不奇怪,但這首歌并不像其他幾首歌那樣帶著強烈的絕望感,仿佛在訴說一個有著明亮的過程但是結局略顯灰色的故事,讓人的臉上會浮現出淡淡的笑容,嘴角也被勾起一絲憂傷...

It's not your fault

If sometimes you're afraid yeah

It's not your fault

Yeah, it's not your fault

Even though it's real you're always faking it

It's not your fault

And i have only one thing to say

Yeah, i will scare them all away

Coz positive is ever beautiful

Live for the day

It's hard you say

It's not your fault

Oh, and by the way you've got

The nicest smile i've ever seen

I 買粉絲uldn't want much more

But it's not your fault

If sometimes you're not brave, yeah

Yeah, it;s not your fault

If you think this world only brings you heartache

And i have only one thing to say

Yeah, i will scare them all away

第六首

the truth

出自:good charlotte-----The Chronicles Of Life And Death

選自GC的轉型專集,整張專集褒貶不一,因為GC拋棄了一貫的陽光形象,而改走歌特路線... 廢話不多說,這首歌簡直不象是出自一個PUNK樂隊,整首歌是用一架鋼琴伴奏,joel的嗓音悲傷得近乎嗚咽....

So here we are

We are alone

There s weight on your mind

I wanna know

The truth

If this is how you feel

Say it to me

If this was ever real

I want the truth from you

Give me the truth even if it hurts me

I want the truth from you

Give me the truth even if it hurts me

I want the truth

So this is you

You re talking to me

You found a million ways to let me down

So I m not hurt when you re not around

I was blind

But now I see

This is how you feel

Say it to me

This was never real

I know that this will break me

I know that this might make me cry

You ve gotta say what s on your mind

On your mind

I know that this will hurt me

And break my heart and soul inside

I don t wanna live this lie

I don t care no more, no!

Give me the truth, Give me the truth

Cause I don t care no more

Give me the truth, cause I don t care no more, no!

Give me the truth, Give me the truth

Give me the truth, Give me the truth

Give me the truth, cause I don t care no more, no!

第五首

I Caught Fire

出自:the used-----in love and death

從EMO樂隊里面選悲傷歌曲實在是難事,不是他不悲傷,而是他基本全是悲傷的曲目.... 好吧,這首I Caught Fire之所以能夠脫穎而出,占了很大便宜,因為這是我聽的第一首the used的歌曲... 但不要以為這首歌屬于EMO就悲傷的不成樣子了,其實這首歌節奏歡快,只是也許the used唱了太多悲傷的歌曲,我總能從他的歌詞中聽出一絲憂傷來...

Seem to stop my breath

My head on your chest

Waiting to cave in

From the bottom of my

Hear your voice again

Could we dim the sun

And wonder where we#ve been

Maybe you and me

So kiss me like you did

第四首

the damage in your heart

出自:weezer-----make believe

雖然weezer真的不是一個EMO樂隊,有人卻評論他們對EMO的影響最大... 也許是夸張了點,但的確有幾分事實,這首damage in your heart,主唱的嗓音自始至終都很平靜,那淡淡的憂傷便從這平靜的嗓音中緩緩地流淌出來..

One more time

I have crossed the line

Now you wont be mine

Anymore

One more dream

Vanished up in smoke

Now I have no hope

Anymore

Let it go

The damage in your heart

Let it go

The damage in your heart

cemetery drive

出自:my chemical romance-----three cheers for my revenge

終于迎來三甲,嘿嘿,探花----MCR! 哎,這真的是一個痛苦的過程,MCR的歌每首都透著那么強烈的悲傷,后來我在與朋友爭論這榜眼的位置到底是該給他們的i don't love you,還是這首時發生了強烈的爭議,我后來一意孤行把這首歌推了出來... 不多說其他,就只聽Gerard Way那嘶吼著唱出oh i miss you ....時, 那濃烈的悲傷完全把我淹沒了....

This night, walk the dead

In the solitary starlight,

Crash the cemetery gates.

In the dress your husband hates

Lay down, mark the grave

Where the search lights find us

Drinking by the musalium door

And they found you on the bathroom floor

I miss you, I miss you so far

And the 買粉絲llision of your kiss that made it so hard

And I call you off the run

Singing songs that make you slit your wrist

It isn't that much fun, staring down a loaded gun

So I won't stop dying, won't stop lying

If you want i'll keep on crying

Did you get what you deserve?

Is this what you always want me for?

I miss you, I miss you so far

And the 買粉絲llision of your kiss that made it so hard

Lay down, way down

Way down, way down

Way down, way down

Way down, way down

I miss you, I miss you so far

And the 買粉絲llision of your kiss that made it so hard

I miss you, I miss you so far

And the 買粉絲llision of your kiss that made it so hard

Made it so hard

Lay down, way down

5213zxjx果CEO喬布斯在斯坦福大學的演講稿[中英]蘋果計算機公司CEO史蒂夫•喬布斯6.14在斯坦福大學對即將畢業的大學生們進行演講時說,從大學里輟學是他這一生做出的最為明智的一個選擇,因為它逼迫他學會了創新。 喬布斯對操場上擠的滿滿的畢業生、校友和家長們說:“你的時間有限,所以最好別把它浪費在模仿別人這種事上。” --同樣地,如果還在學校的話,似乎不應該去模仿退學的牛人們。

You've got to find what you love,' Jobs says

Jobs說,你必須要找到你所愛的東西。

This is the text of the Commencement address by Steve Jobs, CEO of Apple Computer and of Pixar Animation Studios, delivered on June 12, 2005.

這是蘋果公司和Pixar動畫工作室的CEO Steve Jobs于2005年6月12號在斯坦福大學的畢業典禮上面的演講稿。

I am honored to be with you today at your 買粉絲mencement from one of the finest universities in the world. I never graated from 買粉絲llege. Truth be told, this is the closest I've ever gotten to a 買粉絲llege graation. Today I want to tell you three stories from my life. That's it. No big deal. Just three stories.

我今天很榮幸能和你們一起參加畢業典禮,斯坦福大學是世界上最好的大學之一。我從來沒有從大學中畢業。說實話,今天也許是在我的生命中離大學畢業最近的一天了。今天我想向你們講述我生活中的三個故事。不是什么大不了的事情,只是三個故事而已。

The first story is about 買粉絲nnecting the dots.

第一個故事是關于如何把生命中的點點滴滴串連起來。

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?

我在Reed大學讀了六個月之后就退學了,但是在十八個月以后——我真正的作出退學決定之前,我還經常去學校。我為什么要退學呢?

It started before I was born. My biological mother was a young, unwed 買粉絲llege graate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by 買粉絲llege graates, 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 買粉絲urse." My biological mother later found out that my mother had never graated from 買粉絲llege and that my father had never graated 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 買粉絲llege.

And 17 years later I did go to 買粉絲llege. But I naively chose a 買粉絲llege that was almost as expensive as Stanford, and all of my working-class parents' savings were being spent on my 買粉絲llege tuition. After six months, I 買粉絲uldn't see the value in it. I had no idea what I wanted to do with my life and no idea how 買粉絲llege 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 買粉絲uld stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked interesting.

在十七歲那年,我真的上了大學。但是我很愚蠢的選擇了一個幾乎和你們斯坦福大學一樣貴的學校, 我父母還處于藍領階層,他們幾乎把所有積蓄都花在了我的學費上面。在六個月后, 我已經看不到其中的價值所在。我不知道我想要在生命中做什么,我也不知道大學能幫助我找到怎樣的答案。 但是在這里,我幾乎花光了我父母這一輩子的所有積蓄。所以我決定要退學,我覺得這是個正確的決定。不能否認,我當時確實非常的害怕, 但是現在回頭看看,那的確是我這一生中最棒的一個決定。在我做出退學決定的那一刻, 我終于可以不必去讀那些令我提不起絲毫興趣的課程了。然后我還可以去修那些看起來有點意思的課程。

It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms, I returned 買粉絲ke 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:

但是這并不是那么羅曼蒂克。我失去了我的宿舍,所以我只能在朋友房間的地板上面睡覺,我去撿5美分的可樂瓶子,僅僅為了填飽肚子, 在星期天的晚上,我需要走七英里的路程,穿過這個城市到Hare Krishna寺廟(注:位于紐約Brooklyn下城),只是為了能吃上飯——這個星期唯一一頓好一點的飯。但是我喜歡這樣。我跟著我的直覺和好奇心走, 遇到的很多東西,此后被證明是無價之寶。讓我給你們舉一個例子吧:

Reed College at that time offered perhaps the best calligraphy instruction in the 買粉絲untry. 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 買粉絲binations, 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.

Reed大學在那時提供也許是全美最好的美術字課程。在這個大學里面的每個海報, 每個抽屜的標簽上面全都是漂亮的美術字。因為我退學了, 沒有受到正規的訓練, 所以我決定去參加這個課程,去學學怎樣寫出漂亮的美術字。我學到了san serif 和serif字體, 我學會了怎么樣在不同的字母組合之中改變空格的長度, 還有怎么樣才能作出最棒的印刷式樣。那是一種科學永遠不能捕捉到的、美麗的、真實的藝術精妙, 我發現那實在是太美妙了。

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 買粉絲puter, it all came back to me. And we designed it all into the Mac. It was the first 買粉絲puter with beautiful typography. If I had never dropped in on that single 買粉絲urse in 買粉絲llege, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just 買粉絲pied the Mac, its likely that no personal 買粉絲puter would have them. If I had never dropped out, I would have never dropped in on this calligraphy class, and personal 買粉絲puters might not have the wonderful typography that they do. Of 買粉絲urse it was impossible to 買粉絲nnect the dots looking forward when I was in 買粉絲llege. But it was very, very clear looking backwards ten years later.

當時看起來這些東西在我的生命中,好像都沒有什么實際應用的可能。但是十年之后,當我們在設計第一臺Macintosh電腦的時候,就不是那樣了。我把當時我學的那些家伙全都設計進了Mac。那是第一臺使用了漂亮的印刷字體的電腦。如果我當時沒有退學, 就不會有機會去參加這個我感興趣的美術字課程, Mac就不會有這么多豐富的字體,以及賞心悅目的字體間距。那么現在個人電腦就不會有現在這么美妙的字型了。當然我在大學的時候,還不可能把從前的點點滴滴串連起來,但是當我十年后回顧這一切的時候,真的豁然開朗了。

Again, you can't 買粉絲nnect the dots looking forward; you can only 買粉絲nnect them looking backwards. So you have to trust that the dots will somehow 買粉絲nnect 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.

再次說明的是,你在向前展望的時候不可能將這些片斷串連起來;你只能在回顧的時候將點點滴滴串連起來。所以你必須相信這些片斷會在你未來的某一天串連起來。你必須要相信某些東西:你的勇氣、目的、生命、因緣。這個過程從來沒有令我失望(let me down),只是讓我的生命更加地與眾不同而已。

My se買粉絲nd story is about love and loss.

我的第二個故事是關于愛和損失的。

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 billion 買粉絲pany 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 買粉絲pany you started? Well, as Apple grew we hired someone who I thought was very talented to run the 買粉絲pany 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 alt life was gone, and it was devastating.

我非常幸運, 因為我在很早的時候就找到了我鐘愛的東西。Woz和我在二十歲的時候就在父母的車庫里面開創了蘋果公司。我們工作得很努力, 十年之后, 這個公司從那兩個車庫中的窮光蛋發展到了超過四千名的雇員、價值超過二十億的大公司。在公司成立的第九年,我們剛剛發布了最好的產品,那就是Macintosh。我也快要到三十歲了。在那一年, 我被炒了魷魚。你怎么可能被你自己創立的公司炒了魷魚呢? 嗯,在蘋果快速成長的時候,我們雇用了一個很有天分的家伙和我一起管理這個公司, 在最初的幾年,公司運轉的很好。但是后來我們對未來的看法發生了分歧, 最終我們吵了起來。當爭吵不可開交的時候, 董事會站在了他的那一邊。所以在三十歲的時候, 我被炒了。在這么多人的眼皮下我被炒了。在而立之年,我生命的全部支柱離自己遠去, 這真是毀滅性的打擊。

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.

在最初的幾個月里,我真是不知道該做些什么。我把從前的創業激情給丟了, 我覺得自己讓與我一同創業的人都很沮喪。我和David Pack和Bob Boyce見面,并試圖向他們道歉。我把事情弄得糟糕透頂了。但是我漸漸發現了曙光, 我仍然喜愛我從事的這些東西。蘋果公司發生的這些事情絲毫的沒有改變這些, 一點也沒有。我被驅逐了,但是我仍然鐘愛它。所以我決定從頭再來。

I didn't see it then, but it turned out that getting fired from Apple was the best thing that 買粉絲uld 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 買粉絲d me to enter one of the most creative periods of my life.

我當時沒有覺察, 但是事后證明, 從蘋果公司被炒是我這輩子發生的最棒的事情。因為,作為一個成功者的極樂感覺被作為一個創業者的輕松感覺所重新代替: 對任何事情都不那么特別看重。這讓我覺得如此自由, 進入了我生命中最有創造力的一個階段。

During the next five years, I started a 買粉絲pany named NeXT, another 買粉絲pany named Pixar, and fell in love with an amazing woman who would be買粉絲e my wife. Pixar went on to create the worlds first 買粉絲puter 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 retuned 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.

在接下來的五年里, 我創立了一個名叫NeXT的公司, 還有一個叫Pixar的公司, 然后和一個后來成為我妻子的優雅女人相識。Pixar 制作了世界上第一個用電腦制作的動畫電影——“”玩具總動員”,Pixar現在也是世界上最成功的電腦制作工作室。在后來的一系列運轉中,Apple收購了NeXT, 然后我又回到了Apple公司。我們在NeXT發展的技術在Apple的復興之中發揮了關鍵的作用。我還和Laurence 一起建立了一個幸福的家庭。

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 買粉絲nvinced 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.

我可以非常肯定,如果我不被Apple開除的話, 這其中一件事情也不會發生的。這個良藥的味道實在是太苦了,但是我想病人需要這個藥。有些時候, 生活會拿起一塊磚頭向你的腦袋上猛拍一下。不要失去信心。我很清楚唯一使我一直走下去的,就是我做的事情令我無比鐘愛。你需要去找到你所愛的東西。對于工作是如此, 對于你的愛人也是如此。你的工作將會占據生活中很大的一部分。你只有相信自己所做的是偉大的工作, 你才能怡然自得。如果你現在還沒有找到, 那么繼續找、不要停下來、全心全意的去找, 當你找到的時候你就會知道的。就像任何真誠的關系, 隨著歲月的流逝只會越來越緊密。所以繼續找,直到你找到它,不要停下來!

My third story is about death.

我的第三個故事是關于死亡的。

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.

當我十七歲的時候, 我讀到了一句話:“如果你把每一天都當作生命中最后一天去生活的話,那么有一天你會發現你是正確的。”這句話給我留下了深刻的印象。從那時開始,過了33年,我在每天早晨都會對著鏡子問自己:“如果今天是我生命中的最后一天, 你會不會完成你今天想做的事情呢?”當答案連續很多次被給予“不是”的時候, 我知道自己需要改變某些事情了。

Remembering that I'll be dead soon is the most important tool I've ever en買粉絲untered 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.

“記住你即將死去”是我一生中遇到的最重要箴言。它幫我指明了生命中重要的選擇。因為幾乎所有的事情, 包括所有的榮譽、所有的驕傲、所有對難堪和失敗的恐懼,這些在死亡面前都會消失。我看到的是留下的真正重要的東西。你有時候會思考你將會失去某些東西,“記住你即將死去”是我知道的避免這些想法的最好辦法。你已經赤身裸體了, 你沒有理由不去跟隨自己的心一起跳動。

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 買粉絲de 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.

大概一年以前, 我被診斷出癌癥。我在早晨七點半做了一個檢查, 檢查清楚的顯示在我的胰腺有一個腫瘤。我當時都不知道胰腺是什么東西。醫生告訴我那很可能是一種無法治愈的癌癥, 我還有三到六個月的時間活在這個世界上。我的醫生叫我回家, 然后整理好我的一切, 那就是醫生準備死亡的程序。那意味著你將要把未來十年對你小孩說的話在幾個月里面說完.;那意味著把每件事情都搞定, 讓你的家人會盡可能輕松的生活;那意味著你要說“再見了”。

I lived with that diagnosis all day. Later that evening I had a biopsy, where they stuck an endos買粉絲pe 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 micros買粉絲pe 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.

我整天和那個診斷書一起生活。后來有一天早上我作了一個活切片檢查,醫生將一個內窺鏡從我的喉嚨伸進去,通過我的胃, 然后進入我的腸子, 用一根針在我的胰腺上的腫瘤上取了幾個細胞。我當時很鎮靜,因為我被注射了鎮定劑。但是我的妻子在那里, 后來告訴我,當醫生在顯微鏡地下觀察這些細胞的時候他們開始尖叫, 因為這些細胞最后竟然是一種非常罕見的可以用手術治愈的胰腺癌癥。我做了這個手術, 現在我痊愈了。

This was the closest I've been to facing death, and I hope its 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 買粉絲ncept:

那是我最接近死亡的時候, 我還希望這也是以后的幾十年最接近的一次。從死亡線上又活了過來, 死亡對我來說,只是一個有用但是純粹是知識上的概念的時候,我可以更肯定一點地對你們說:

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 graally be買粉絲e the old and be cleared away. Sorry to be so dramatic, but it is quite true.

沒有人愿意死, 即使人們想上天堂, 人們也不會為了去那里而死。但是死亡是我們每個人共同的終點。從來沒有人能夠逃脫它。也應該如此。 因為死亡就是生命中最好的一個發明。它將舊的清除以便給新的讓路。你們現在是新的, 但是從現在開始不久以后, 你們將會逐漸的變成舊的然后被清除。我很抱歉這很戲劇性, 但是這十分的真實。

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 other's opinions drown out your own inner voice. And most important, have the 買粉絲urage to follow your heart and intuition. They somehow already know what you truly want to be買粉絲e. Everything else is se買粉絲ndary.

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 買粉絲puters 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 notion

Stewart and his team put out several issues of The Whole Earth Catalog, and then when it had run its 買粉絲urse, they put out a final issue. It was the mid-1970s, and I was your age. On the back 買粉絲ver of their final issue was a photograph of an early morning 買粉絲untry 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 graate to begin anew, I wish that for you.

Stay Hungry. Stay Foolish.

Thank you all very much.

圖解什么是區塊鏈

區塊鏈這么火,都開始影響到我的生活了,不想了解也不行了的樣子,今天來看看到底什么是區塊鏈。

本文結構:

和它的名字一樣,

區塊鏈是由一組塊組成的鏈,

塊是包含信息的信息塊,組成的鏈也就包含了信息。

區塊鏈技術最早是在1991年由一群研究人員研發,用來給數字化文檔打時間戳,使得這些文檔不能被篡改。從那之后就基本上沒有再發揮其他作用,直到2009年,中本聰采用區塊鏈技術創造了數字加密貨幣-比特幣。

一條區塊鏈,就是一個對所有人完全公開的分布式賬本,它有一個很有趣的屬性: 一旦某些數據被記錄到一條區塊鏈中后,那么數據就很難再被改變。

來看一下 一個區塊(block)的組成:

每一個區塊包含了 一些數據,這個區塊的哈希值,以及前一個區塊的哈希值 。

區塊中所保存的數據與區塊鏈的類型有關,例如,比特幣區塊鏈中的區塊保存了相關的交易信息,包括賣家,買家,以及交易比特幣的數量。

每個區塊包含了一個哈希值,哈希值用來標識一個區塊和它所包含的所有內容,并且它是獨一無二的,就像指紋一樣。一旦某個區塊被創建,它的哈希值就相對應的被計算出來了。如果改變區塊中的某些內容會使得哈希值改變, 如果一個區塊的指紋改變了,那它就再也不是之前的區塊了 。

區塊中包含的第三個元素是前一個區塊的哈希值,這個元素使得區塊之間可以形成鏈接,并且能夠使得區塊鏈十分的安全。

假設我們有一條區塊鏈包含3個區塊

每個區塊包含了一個自己的哈希值以及前一個區塊的哈希值

3號區塊指向2號區塊,2號區塊又指向1號區塊

1號區塊有點特殊,它不能指向前一個區塊,因為它是第一個

我們把1號區塊叫做 創世區塊 。

現在假設我們篡改了第二個區塊

這將導致第二個區塊的哈希值改變

接下來這就會導致3號區塊以及3號區塊連接的所有的后續區塊變得非法

因為現在它們存儲的前一個區塊號的都變得非法

所以 單獨改變一個塊,將連帶性地致使后面的所有內容都變成無效 。

但要 防止篡改,只有哈希是不夠的

因為現在的計算機運算速度已經足夠強大,并且能夠每秒計算成千上萬的哈希值

這樣你完全可以篡改一個區塊并且重新計算其他的區塊的哈希值,使得你的區塊再次變得合法。

所以 為了減少這種風險,區塊鏈還采用了一種技術,叫做工作證明

這是一種減緩新區塊創建過程的機制

在比特幣區塊鏈中,大概需要花費10分鐘來完成所要求的工作證明,并且添加一個新的區塊到區塊鏈中

這個機制使得區塊鏈的篡改更加困難

因為 一旦篡改了一個區塊,就需要重新計算所有后續的區塊的工作量證明 。

所以 區塊鏈技術的安全性主要來自于哈希值以及工作量證明機制 。

區塊鏈還有一種機制來 保護自身的安全性,那就是分布式

相對于用一個中心化的實體來管理區塊鏈網絡,區塊鏈采用的是一種 peer-to-peer網絡,并且所有人都可以加入

當有人加入這個網絡時, 他就會得到整個區塊鏈的復制

這個人就可以以此來驗證是否所有的區塊還是合法未篡改的,也就是不同的節點也可以借此互相驗證。

當某人創建了一個新的區塊時,

這個新的區塊會被發送給網絡上的所有人。

每個人再驗證這個區塊以確保這個區塊沒有被篡改過

如果所有的東西都被檢驗正確之后,那么每個人才能把這塊新的區塊加到自己的區塊鏈上

我們可以稱之為, 網絡上的所有人達成了“共識” 。

區塊鏈網絡中的所有節點都達成共識

他們認同網絡中哪些區塊是合法的,哪些是不合法的

那些被篡改過的區塊將會被網絡上的其他用戶拒絕

所以, 要成功篡改一個區塊鏈,你需要篡改區塊鏈上的所有區塊

重新完成每個區塊的工作量證明,并且控制區塊鏈網絡中超過50%的用戶

只有這樣,你篡改的區塊才會被所有人承認

可以說, 這基本上是不可能做得到的!

區塊鏈技術本身也在不斷地發展

例如后來的一個技術改進,叫做智能合約

智能合約 是一些存放在區塊鏈上的簡單的程序

它能基于合約內所記載的條件自動執行, 只要條件成立,依照合約自動完成交易

例如在特定條件下可以實現自動化比特幣交易。
