I'm a professor of computer science at UC Berkeley.

我是加州大學柏克萊分校電腦科學的教授。

to 不定詞

I am here today to answer your questions from the Internet.

我今天在這裡要回答大家來自網路上的一些問題。

It depends on if it's a reference to Latex or not.

Says what remnants of the early World Wide Web are left.

說的是早期全球資訊網還剩下些什麼。

It turns out that the first website that was ever put up is still available to us.

結果發現，最早建立的網站到現在都還能看得到。

So I actually have it here on my laptop right now.

所以，我現在的筆記型電腦上就帶著它。

So this is a webpage put up in the early 90s.

所以這是一個在九零年代初期的網頁。

It's describing what the World Wide Web is because Tim Berners Lee is actually the person who created the World Wide Web.

它在描述全球資訊網是什麼，因為 Tim Berners Lee 其實就是創造全球資訊網的人。

And we can see that it still displays in a totally readable and manageable manner in our modern web browsers.

而且我們可以看到，在我們現代的網頁瀏覽器裡，它仍然能以完全可讀且易於管理的方式顯示。

someone also actually recreated what it would have looked like in a browser of that time.

有人也真的重現了它在那個時代的瀏覽器裡看起來會是什麼樣子。

So here we can see we've got the World Wide Web.

所以在這裡我們可以看到，我們有全球資訊網。

of course it shows up very differently because the machinery they were working with at the time was working differently.

當然，它顯示出來的方式非常不同，因為他們當時使用的機械設備運作方式也不同。

The browsers they had made at the time were working differently.

當時他們製作的瀏覽器運作方式不同。

It's giving us instructions on how to actually browse through the rest of the page.

它給我們訓示，教我們如何瀏覽網頁的其餘部分。

Obviously it's showing up a little bit differently.

當然，它顯示出來的方式有點不同。

AdmirableLong9546 asks, new to coding, is it always this difficult?

AdmirableLong9546 問，剛開始學編碼，是不是一直都這麼難？

Every skill that you have ever learned in your life where parts of it became automatic over time when you started riding a bike, eventually became automatic when you started playing guitar started becoming automatic.

你生命中學過的每一項技能，當你開始騎腳踏車時，有些部分隨著時間變得自動，當你開始彈吉他時，也變得自動。

The exact same thing is going to happen with programming.

程式設計也會發生完全相同的情況。

No confidence 5070 oh, I'm sorry about the username.

No confidence 5070 喔，我很抱歉 username。

Asks, can I still learn programming if I hate math?

問，如果我討厭數學，還能學程式設計嗎？

So there are some kinds of math that make some kinds of programming easier, but

所以有些數學會讓某些程式設計更容易，但是

it's not all kinds of math and it's not all kinds of programming for that matter.

並非所有數學都如此，而且程式設計本身也並非如此。

There's some kinds of video games that give you practice with some of the things that make programming easier.

有些電玩遊戲能讓你練習到一些能讓程式設計更容易的技巧。

Like there are lots of different skills out there that you might be practicing that might help you with some of the same things that you're going to need in order to do coding tasks.

就像有很多不同的技能，你可能正在練習，這些技能可能會幫助你掌握一些你為了完成編碼任務所需要的東西。

There are certainly there are some types of computer programming that, that you might want to do that probably would demand a little math from you.

當然，有些類型的電腦程式設計，你可能想做，但那可能需要你具備一些數學能力。

So there are parts of the computer programming world where you probably want to be comfortable with some parts of math.

所以電腦程式設計的世界裡，有些部分你可能希望對數學有所掌握。

But no, you can absolutely, absolutely, absolutely get into programming, get really good at programming without being into math.

但是，你絕對、絕對、絕對可以投入程式設計，並且非常擅長程式設計，而不需要數學。

Someone on the Internet asks, what were the earliest computer viruses?

有人在網路上問，最早的電腦病毒是什麼？

Like how did they infect and affect computers?

像是它們是如何感染和影響電腦的？

In about the early 70s, computers had started to be sort of connected with each other through something called the arpanet.

大約在七零年代初期，電腦開始透過一個叫做 arpanet 的東西互相連接。

We didn't have the Internet yet, and so you could go ahead and start spreading things that way.

那時候我們還沒有網際網路，所以你可以開始透過那樣的方式散播東西。

And there was this, this virus called the Creeper.

然後出現了一個叫做 Creeper 的病毒。

It would print something out on the screen that said something like, I'm the Creeper, catch me if you can.

它會在螢幕上印出一些文字，像是「我是 Creeper，有本事就抓我」。

Then they had to come up with the reaper to go in and get rid of the Creeper program that was running on these machines.

然後他們必須開發出 Reaper 來清除那些在這些機器上運行的 Creeper 程式。

Demand2010 asks, how did programmers code the first ever code?

Demand2010 問，程式設計師是如何編寫第一個程式碼的？

And the ENIAC was sort of the first computer that we all look at by modern standards and say, yep, to us that looks like a general purpose computer.

而 ENIAC 算是第一臺我們以現代標準來看，會說「嗯，對我們來說這看起來是一臺通用電腦」的電腦。

It looks a lot like sort of old school telephone switchboards where you're just plugging together wires and different parts of it.

它看起來很像那種老式的電話交換機，你只是把線路和不同的零件接在一起。

That's actually how you're communicating what you want it to do.

那就是你溝通你想要它做什麼的方式。

Eventually folks figured out how to use punch cards, stiff piece of cardstock kind of a thing, and

終於大家想出瞭如何使用打孔卡，那是一種硬紙板的東西，然後

And that was the way that we fed instructions into computers for a long time before we started storing programs in memory.

這就是我們在電腦記憶體儲存程式之前，很長一段時間輸入電腦訓示的方式。

So originally the humans were just writing those ones and zeros.

所以最初人類只是在寫那些一和零。

All this manual effort was really exhausting.

所有這些手動的努力真的很累人。

And so this amazing thinker, Grace Hopper, developed the term compiler.

然後，這位了不起的思想家 Grace Hopper，就發展出了「編譯器」這個詞。

Grace Hopper was this amazing early computing pioneer.

Grace Hopper 是早期計算領域一位了不起的先驅。

She was a mathematician, she was incredible and came up with the idea that instead of all these human people doing compilation, we should have a program on the machine that is actually going to do the compiling for us.

她是一位數學家，她非常厲害，她想到一個主意，與其由人類來進行編譯，我們應該讓機器上的一個程式來為我們實際執行編譯。

And she invented this tool called a zero for putting together a bunch of different sort of portions of a program, a bunch of different sort of semi related portions of code and getting them to talk to each other.

她發明瞭這個叫做 zero 的工具，用來組合程式中許多不同的部分，許多有點相關的程式碼片段，讓它們能夠互相溝通。

And that was sort of the predecessor to the modern compiler.

這可以說是現代編譯器的前身。

In fact, since that time we have piled all this extra stuff on top of it so that the thing that Grace Hopper wrote in the early 50s actually no longer even looks like a compiler to us.

事實上，從那時起，我們在上面堆疊了所有這些額外的東西，所以 Grace Hopper 在 50 年代早期寫的東西，對我們來說其實已經不像編譯器了。

It looks like one of the sort of sub components of a compiler because we have all this other stuff that we've built up on top of it.

它看起來像是編譯器的其中一個子元件，因為我們在上面建構了所有這些其他東西。

Bettersir9013 what is the difference between programming languages?

Bettersir9013，程式語言之間有什麼差別？

Why are some of them considered harder if they're all just same lines of code?

為什麼有些語言會比較難，如果它們都只是同樣的程式碼行？

There are lots of different things that can set programming languages apart.

有很多不同的東西可以讓程式語言區分開來。

A big thing that I tend to think about is how much they sort of have your back.

我比較常想到的一點是，它們在多大程度上會「罩著你」。

So a really common thing is for a programming language to be automatically trying to capture some kinds of bugs for you, trying to prevent you from running into some of the problems that might come back to bite you later.

所以一個很常見的情況是，程式語言會自動幫你捕捉某些類型的錯誤，試圖阻止你遇到一些日後可能讓你後悔的問題。

Some of them are saying, you know what, you're on your own.

有些語言則會說，你知道嗎，你自己處理吧。

Put in whatever bugs you want to put in, I'm going to run it for you.

你想放什麼錯誤就放什麼錯誤，我都會幫你執行。

So an example of something in that general category would be C.

There are other programming languages that are saying, you know what, I'm going to try to catch at least some bugs for you.

也有其他的程式語言會說，你知道嗎，我會試著至少幫你捕捉一些錯誤。

I'm going to try to catch some bugs and I'm going to try not to get in your way.

我會試著捕捉一些錯誤，而且我不會妨礙你。

I'm not going to try to demand a lot of extra information from you in order to do that.

我不會試圖要求你提供很多額外的資訊來做到這一點。

And so an example of something in that class would be maybe Python, and

所以這類型的例子可能是 Python，然後

then you might have some other language over here that is really, really trying to have your back.

你可能會在這裡有另一種語言，它真的、真的會支持你。

It is going to try to catch as many bugs for you as it can possibly catch.

它會盡可能多地為你捕捉錯誤。

And the way that it's going to do that is it's going to demand extra information from you.

它會這樣做的原因是，它會向你要求額外的資訊。

So it's going to make you work harder, but

所以它會讓你更努力工作，但是

in exchange, it's going to catch all those bugs for you.

相對地，它會為你捕捉所有這些錯誤。

Example of something in that general zone would be Rust.

屬於這個大範圍的例子是 Rust。

Faintshai asks, working as a programmer, what do you actually do all day at work?

Faintshai 問，身為程式設計師，你一天在工作上到底做些什麼？

Unfortunately, the answer is not as much programming as you might desire.

不幸的是，實際寫程式的時間並沒有你期望的那麼多。

In general, a lot of programmers get into programming because they like programming, and

一般來說，很多程式設計師之所以投入程式設計，是因為他們喜歡寫程式，然後

then it turns out that a lot of what they're spending their day to day on is talking with other programmers about how to get this person's piece of code to talk with this person's piece of code, how to make all of this big code base work together.

結果發現他們每天花費大量時間在跟其他程式設計師討論，如何讓這個人的程式碼跟那個人的程式碼溝通，如何讓整個龐大的程式碼庫協同運作。

Or you're talking to the client or the customer or someone who's going to be using this piece of code, and

或者，你正在跟客戶、使用者或某個將要使用這段程式碼的人溝通，

you're figuring out what their needs are.

You're having a bunch of meetings in order to figure out what the program should actually do, and

你們會開一堆會議來弄清楚程式到底應該做什麼，然後

then you're squeezing in as much of that actual coding time as you can, because that's usually the Fun part.

再把實際寫程式的時間盡量擠進來，因為那通常是比較有趣的部分。

DG Holmes asks, is Python really the second best language for everything?

DG Holmes 問，Python 真的什麼都排第二名嗎？

I think probably whoever said this first, honestly, they were probably trying to get a dig in on Python a little bit.

我想，說這句話的人，老實說，可能有點想酸一下 Python。

Kind of trying to say that it's not the first best language for anything.

感覺像是想說它什麼都不是第一名。
