thousandknives··on Scientists discover 100 to 1000 times more plastics in bottled water
I am from Austria, and here you can buy water in cans. It's not common, but lately, there are 2-3 brands that offer canned water, which you can find in a normal supermarket.

On the other hand, I've never seen water in cartons in my life.

But both cans and cartons are also lined with plastic on the inside, afaik.

I was seeing "When Chinese Industrial Espionage Goes Wrong" [1] some months age, industrial espionage related to the inside coatings of the cans. Quite interesting video.

Well, he writes himself:

*The book is augmented in places to help understand its rightful place in a historical context amidst the major changes of the 1970's and 1980's as Computer Science evolved from a hardware-first / vendor-centered aproach to a software-centered approach where portable operating systems and applications written in C could run on any hardware.

This is not the ideal book to learn C programming because the 1978 edition does not reflect the modern C language. Using an obsolete book gives us an opportunity to take students back in time and understand how the C language was evolving as it laid the ground work for a future with portable applications.*

I assume the exercises are to be written in ANSI C, though I haven't attempted one yet

I watched his "Internet History, Technology, and Security" course. That one was phenomenal.

Now I discovered this course, the first two videos in that YouTube playlist are very interesting (A History of C, UNIX, and Computation (a.k.a "The importance of 1978")).

There is also a course website to this with a lot of additional material, but it requires a password (it is "42"), that's why I submit the YouTube playlist.

Small misunderstanding.

With hardware I meant the LEDs/LED matrix. What kind of LEDs did you use and how much did it cost you is what I wanted to know...

How much did that cost you to build? What kind of hardware did you use?

I'm not entirely sure from the website - the lectures will be recorded and posted online for everyone to access?
