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

To-infinitive

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

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

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

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

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

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

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

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

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

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

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

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

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

Obviously it's showing up a little bit differently.

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

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.

The exact same thing is going to happen with programming.

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

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

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

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

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

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.

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.

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

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

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

Like how did they infect and affect computers?

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

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

And there was this, this virus called the Creeper.

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

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.

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

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.

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

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

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

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

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

All this manual effort was really exhausting.

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

Grace Hopper was this amazing early computing pioneer.

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.

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.

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

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.

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?

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.

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

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.

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

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

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.

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

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

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

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

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

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

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

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

Example of something in that general zone would be Rust.

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

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

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

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.

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

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

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

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

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

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