Hello world!

I’m Carrie Anne Philbin and welcome to Crash Course Computer Science!

So, computers really have allowed us to do some pretty amazing things - think global telecommunications, international commerce, global transportation, breakthroughs in medicine, distributed education, online shopping, online dating, just the Internet in general.

So before we get into what we are going to talk about in this course, it might be useful to tell you what we aren’t going to talk about. We aren’t going to teach you how to program.

Programming is a really crucial aspect of computer software, and we will get to the rules that guide the logic of hardware and software design. But we aren’t going to teach you how to program an Arduino Uno to water your plant or how to change the CSS on your grandma’s sewing blog so visitors’ cursors turn into kittens.

This also isn’t a computing course. Or at least how computing is thought of in the U.S. Computing here is a goal - it’s what computers do. And we’ll talk about some of that for sure, but OUR goal for this course is much broader.

But computing means other things in other countries. It’s all pretty confusing.

What we are going to look at is the history of computers… even before we had electricity. We’re going to retrace the design decisions that have given us our present-day components.

We’re going to talk about how Operating Systems work… or don’t work… how the YouTubes get to you over the Internet, how our smartphones and other smart devices are... well, getting smarter, and of course mysterious futuristic stuff like quantum computing and frustrating present-day stuff like hacking!

It’s a lot to cover, but I suppose before we get started I should introduce myself. I’m Carrie Anne Philbin! Hello!

I'm an award-winning secondary Computing teacher, author of Adventures in Raspberry Pi and the creator of a YouTube video series for teenagers called the Geek Gurl Diaries, which includes stuff like interviews with women working in technology, computer science-based tutorials, and hands-on digital maker-style projects.

In my day job, I help people learn about technology and how to make things with computers as Director of Education for the Raspberry Pi Foundation, which is a charity based in Cambridge in the UK.

Needless to say, I am passionate about this stuff, but not because computers are these amazing devices that are always making our lives easier (sometimes that’s debatable) but because computers inarguably have become pivotal in our society.

From our cars and thermostats to pacemakers and cellphones, computers are everywhere, and it’s my hope that by the end of this course you’ll have a better understanding and appreciation for how far we’ve come and how far they may take us.

I’ll see you next week.
