Keynote: Uninitialized Uses in C++ Programming: The Bytes Before the C++ Types - JF Bastien - C++Online 2024
An in-depth exploration of a subtle aspect of systems programming: uninitialized memory. What are in the bytes before a type exists? This talk dives into the complex world of uninitialized variables, unraveling its mysteries and practical implications. We’ll discuss software security with concrete examples of security vulnerabilities such as information leaks, attacker-controlled values, and use-after-free; performance impact is then explained in-depth; finally, we’ll present mitigations and best practices. The talk delves into memory management on the stack and heap memory, explaining how uninitialized memory issues manifest in each.

The best talk ever.
Detailed explanation where it should be detailed and short when it needs to be short.
10/10.
In a couple of years this talk will be a sensation.
Bravo.
Your comments are much appreciated, thank you so much!
I like this very unique and interesting presentation format. Very nice, much appreciated.
Brilliant talk, thank you very much for sharing. Great production quality, learned loads of interesting stuff, and I'm inspired to to learn more. Very nice gilet as well!

The animations are all done in Keynote.
Thats gem of a talk.
sublime presentation, one of the best i've seen for a long time
Thank you so much for sharing this great stuff.
Even though i knew the topic well, this was a great video and i shared it with my son for his enrichment.
Extremely helpful, thank you.
peace to all my coding brothers
Just have the OS or some security service clear data after an app closes.
That is a pretty long-winded way of saying: uninitialized memory contains garbage and freed memory might still expose your old data.
Sure. Thanks. But not everyone has your knowledge. Everybody is coming from a different knowledge base and understanding. We all pick up knowledge at different times and from different people. The more sources the better.🙄
