Reading wonderful joyofcryptography.com book. This section really gives me chills. I never thought about how much you can learn about the content only using its length.

8.1.1.
The plaintext length side-channel
Encryption cannot completely hide the length of plaintext data. We must accept this fact, even if its consequences are unpleasant. Plaintext length can convey a surprising amount of information and have huge impacts to real-world security! An adversary who observes only the length and timing of your encrypted network traffic can figure out:

which pages you visited on Wikipedia, or any website with relatively static content of different sizes;

which movie you are streaming, because video formats use variable bit-rate (VBR) encodings, so that “busier” segments of the video require more data per second;

or even what you are saying in an encrypted audio call!

See the chapter notes for references about these attacks. Personally speaking, these are the kinds of attacks that give me the most existential dread about cryptography. However, encryption is about more than just hiding the content of communication, as we will see later in section 9.6.

Recently dove into geometric algebra (specifically, 3D plane-based geometric algebra) and wrote a library to handle all the calculations and visualizations. It works! I’m finally free from cross products, quaternions, and complex numbers—it unifies them all in an intuitive way.

Did I miss any other flag?

Nice blog about setting up compiler explorer locally. validark.github.io/posts/local-... I'm so used to waiting 5 second what 0.25 rebuilds are shoking
