i'm old; i graduated in 1979, way before the www was a thing the fact that i can hop onto youtube and drop into a class at MIT like this still blows my mind

I feel so dumb at work sometimes. I had to learn these things the hard way, thank you for putting this out there.

thank you youtube algorithm for this magnificent content

How they teach and covers the topic is really helpful. I think they are doing great work to post these and their notes over internet for people to use. Regards to the authors.

These lecture are amazing, thanks for releasing this to the public!

Im sad this kind of quality instruction is not commonplace across other post secondary institutions.. I guess it is MIT after all... Thanks for making this available

I'm like 15 minutes in, and I'm already thankful to you guys for making this!! For someone who used to be a programmer but left and is now making a comeback, this packs-a-punch.

This is a lecture series I have wanted. Thank you MIT!

the xdg-open in powershell was just: start worked with pdfs and .html files.

Lectures we didn't ask for but we all needed the most.

great! MIT never ever dissapoints me. Hope this quality of education become a standard in the future in every country.

THIS IS WHAT WE ALL NEEDED. THANK YOU FROM THE BOTTOM OF MY HEART.

I came to think again, that we are living very hopeful period of time given that these fruitful and friendly lectures from MIT is ready to be watched free, at all around the world:)

This is awesome. You guys are awesome for sharing it publicly. Everything about this is awesome.

so glad i found this courses. thank you MIT and all who made this!

I'm actually tearing up. I've been trying to learn how to do things and it's been super frustrating and EVERY SINGLE COURSE I have ever seen either teaches you what a variable is. Or has a "google is your best friend" sort of approach. Thank you so much for making these videos

what a great and generous idea to publish these lectures for everyone. Thank you!

Why is this in my recommandations and why am I starting to plan to watch the whole courses

This is exactly what I need! Thank you MIT
