Lesson 7: Losing My Memory

It's hard for me to believe that I've been publishing these mostly-weekly lessons for almost a month and a half. It's been really fun. I hope that those of you reading them have been enjoying reading (and hopefully learning from) them as I have in writing them. This one covers two major topics: memory management and binary math, nothing terribly exciting, but really useful and necessary nonetheless. Learn to Program With Haiku, Lesson 7.

Thanks for these tutorials, very useful. Can't wait to start diving into the Haiku API.

I agree! Very nice tutorials, and I am also eager to see when you arrive to the HAIKU API specific part. :)

The calloc() signature given is not correct. For some (probably weird) reasons it has two arguments:

On page 7, in the XOR example, you listed 36 as 0b00010100, instead of 0b00100100. This was confounding me when I was performing the XOR in my head and couldn't see how you got a 1 in the 16's place, and a 0 in the 32's place.

This is a great tutorial though, good job!

Thanks for pointing out the errata, guys! I've made the necessary corrections and appreciate having them pointed out. :)
