TLS/SSL Certificates - For The Rest Of Us The internet is insecure by default. Attackers can intercept and modify traffic, so we need a way to secure communication and verify the server’s identity. Encryption ensures data privacy, but without verification, hackers could impersonate a legitimate website, intercepting traffic while still using encryption. This is why TLS/SSL combines encryption with authentication.

We will dive into the secret sauce of the technique that is used to optimized it. very low level thing like use the right assembly instruction to make code run in fewer instructions.

Performance optimization, and how to do it wrong I recently tried to optimize convolutions using SIMD instructions, but what I thought would be a simple task ended up taking me days, with issue after issue popping up one after another. Some of them make sense in hindsight, but others were utterly baffling. While the specific examples are for direct convolution, these considerations apply to...
