  I’ve never found a channel that aligns so well with how my brain learns. It’s clear that you genuinely want to teach, not just throw out a bunch of hard-to-digest facts about an already complex topic. Thank you so much for all the effort you put into making these gems.

  Shots fired at Chrome&apos;s memory Usage at <a href="https://www.youtube.com/watch?v=O2tV9q6784k&amp;t=120">2:00</a>, being larger than all the others, together. Thank you very much for the video, this is something I kind of knew but I was missing SO MUCH and, as always, you&apos;ve provided.

  I&apos;ve been on Youtube for 15 years now. I&apos;m a mechanical engineer (do brasil também) but started developing a fascination with computers. I recently watched Ben Eater building a 6502 computer from scratch and finally understood the basics of how a CPU and I/O really works. I wish you existed back then. I would&apos;ve probably pursued a carreer on computer science if I knew how interesting everything happening with the OS at low level really is. You are hands down my favorite Youtuber at the moment. Don&apos;t miss a single video. You explain everything perfectly and in extreme detail. You explain something, then I have some questions, and you immediatly bring them up and explain it, like you&apos;re reading my mind. Liking every video and really hope your channel grows!

  Extremely well done video! 😍<br>Thanks to you, even my designer brain (designer turned C++ programmer) can now understand how a system works, hence my programming has gotten so much better and I even just started learning assembly.<br><br>Now I can&apos;t wait for the next video, maybe I&apos;ll learn how to better optimize my coder for Windows scheduling. 😍
