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

我是 UC Berkeley 的電腦科學教授。

to 不定詞

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

我今天在這裡為大家解答網路上的問題。

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，第一個架設的網站到現在都還能看得到。

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

所以我現在其實已經把它放在我的筆記型電腦上了。

So this is a webpage put up in the early 90s by Tim Berners Lee.

所以這是 Tim Berners Lee 在 90 年代早期架設的一個網頁。

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

它在描述什麼是全球資訊網，因為 Tim Berners Lee 就是發明全球資訊網的人。

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，它在我們現在的網頁瀏覽器裡，還是完全可讀、可管理的樣子。

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會是什麼樣子。

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

所以我們可以看到，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，顯示起來很不一樣，因為他們當時使用的機器運作方式不同。

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

他們當時的瀏覽器運作方式也不同。

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

它給了我們如何實際瀏覽頁面其餘部分的訓示。

Obviously, it's showing up a little bit differently.

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

AdmirablLong9546 問，剛開始學寫程式，都會這麼難嗎？

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.

你人生中學過的任何技能，隨著時間推移，有些部分會變得自動化，像是學騎腳踏車，最後變得自動化；學彈吉他，也開始變得自動化。

The exact same thing is going to happen with programming.

程式設計也會發生同樣的情況。

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

No confidence 5070 喔，抱歉你的使用者名稱。

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

問，如果我討厭數學，還可以學程式設計嗎？

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.

並不是所有數學都這樣，也不是所有程式設計都這樣。

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

有些電玩遊戲可以讓你練習到一些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.

就像外面有很多不同的技能，你可能正在練習，這些技能可能會幫助你掌握一些做程式設計任務時需要用到的東西。

再說一次，也不是所有數學都適用。

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，有些電腦程式設計的類型，你可能想做，但那可能需要你具備一點數學能力。

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，有些部分你可能需要對數學的某些部分感到自在。

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、絕對可以進入程式設計領域，而且在程式設計方面做得很好，不需要懂數學。

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

網路上有人問，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.

那時候還沒有網際網路，所以你可以透過那樣的方式開始散播東西。

And there was this, this virus called the Creeper.

然後就有一個叫做 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，有本事就來抓我」。

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.

然後他們就必須開發出 Reaper 來清除運行在這些機器上的 Creeper 程式。

Demand2010 asks how did programmers code the first ever code?

Demand2010 問，最早的程式是怎麼寫出來的？

非常非常早期的時候，有 ENIAC。

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，以現代標準來看，我們會說，嗯，對我們來說它看起來就像是一臺通用電腦。

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

它看起來很像早期那種電話交換臺，你就是把線路和不同的零件接起來。

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

那其實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

後來大家想出了怎麼使用打孔卡，一種厚紙板的東西，

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，很長一段時間裡輸入指令的方式。

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

所以一開始人類就是直接寫那些一和零。

All this manual effort was really exhausting.

所有這些手動操作真的讓人筋疲力盡。

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

所以這位了不起的思想家 Grace Hopper，就發明瞭編譯器這個詞。

Grace Hopper was this amazing early computing pioneer.

Grace Hopper 是早期電腦領域一位非常傑出的先驅。

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，非常厲害，她想到與其由人類來做編譯，不如讓機器上的程式來幫我們做編譯。

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，用來整合程式裡許多不同部分，許多半相關的程式碼片段，讓它們能互相溝通。

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，從那時候開始，我們在上面堆疊了好多額外的東西，所以 Grace Hopper 在 50 年代早期寫的東西，對我們來說已經不像編譯器了。

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.bettersir9013 what is the difference between programming languages?

它看起來像是編譯器的一個子元件，因為我們在上面建構了好多其他東西。

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

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

為什麼有些語言被認為比較難，但它們都只是同一行行的程式碼？

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

我覺得很重要的一點是，它能在多大程度上支持你。

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，程式語言通常會自動幫你捕捉一些 bug，試圖防止你遇到一些日後可能會讓你頭痛的問題。

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

有些語言則是說，你知道嗎，你自己想辦法。

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

屬於這類型的語言，一個例子就是 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.

有些程式語言則會說，你知道嗎，我至少會試著幫你抓一些 bug。

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

我會試著抓一些 bug，而且我會盡量不阻礙你。

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

我不會為了這樣做而試圖向你要求很多額外的資訊。

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

所以屬於這類型的例子，也許是 Python，然後

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

你可能會發現有另一種語言，它真的、真的會盡力支援你。

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

它會盡量幫你抓到盡可能多的 bug。

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，是因為它會要求你提供額外的資訊。

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

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

相對地，它會幫你抓到所有的 bug。

Example of something in that general zone would be Rust.

屬於這個大方向的例子是 Rust。

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

Faintshai 問，身為一個程式設計師，你一天實際在工作上做些什麼？

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

不幸的是，答案是寫程式的時間不如你期望的那麼多。

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會投入程式設計，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很多時間在跟其他程式設計師討論，要怎麼讓這個人的程式碼跟那個人的程式碼溝通，要怎麼讓整個龐大的程式碼庫能一起運作。

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，你是在跟客戶、顧客，或是即將使用這段程式碼的人溝通，然後

you're figuring out what their needs are.

你在弄清楚他們的需求是什麼。

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

你會開一堆會議，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 是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，大概是想稍微酸一下 Python。

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

But the other way of reading this is to say that Python is very flexible.

但另一種解讀方式是，Python 非常有彈性。
