Operation Binder: Secrets of Computer Process Communication
78,489
Published 2024-08-06
Inter-Process communication is one of the most critical parts of modern operating systems, yet nearly invisible to the user.
Join me as we pull back the curtain on this crucial yet often overlooked technology.
We'll examine both the history and fundamentals of IPC systems, as well as focusing on one that runs on billions of devices worldwide, the Android Binder.
Don't worry, there will be plenty of real-world code examples to follow along!

Laurie, we don't deserve this kind of quality of production
-
we don't deserve the LaurieWired cinematic universe
-
That spy scene with the sea in the background was crazily well shot. Also good introduction to android as Linux based so far.
-
how is she able to make a tech video with such good production quality??????????? very cool
-
My 5 year old daughter thinks you are awesome as do I. You are an awesome role model for her. Keep doing what you do!
-
The amount of care, passion and attention you put into your content is greatly appreciated.
-
I haven't seen anyone put this much effort and attention to detail into a YouTube video. I think this should be a series on Netflix.
-
Laurie ensures we're still in the golden age of educational content on YouTube, at least where compsci is concerned.
-
I've worked in the IT industry for almost 30 years. I'm also an aspiring cinematographer. Laurie has exceeded what I can do on every level, from cybersecurity to the production of her channel. Impressive. Bravo!
-
I love how the guys that talk about low level stuff never disappoint me. They always post the videos I need at the time I need them. right now I am studying for an operating systems exam for example
-
You totally respect the viewer by explaining everything thoroughly. That's something to admire.
-
Yes, please more "dense, technical and challenging" content! I personally prefer it over the "child animated - over simplified" methods I see commonly now. Thank you for the content!
-
The scene at 0:52 shows incredible attention to detail. It shows the Seattle Waterfront with the blue angles performing for Seafair in the background. Given that Seafair was this past weekend, I think this video has been mostly finished for a while and was delayed just to get that shot of the blue angels! Incredible dedication!
-
This was incredible. As an Android dev, I've often wondered how message passing worked and what parcelables were, and how they related to Intents too. The way you broke everything down and built it back up again from the ground up was simply fantastic, and I loved your agent analogy. Seriously well done.
-
The production of LaurieWired is higher than some movies at this point
-
These production levels are off the chart
-
This should be on Netflix.
-
How on earth did you become this thorough in computers!? This is amazing, I always learn so much watching your videos! Great quality too!
-
sheeeeeeshhh that intro mirror shot tho, that shot on the elevator and balcony over looking the Ferris wheel and ocean, the 2 jets in the background. That was fire!
-
Density of learning is marvelous. I am not a Android developer, but I get it, and now I know how IPC and Binder works.
