OpenSSL 3.5.0 has been released, introducing support for various post-quantum cryptography (PQC) methods and the 0-RTT (Zero Round Trip Time) feature. Traditionally, the three-way handshake (SYN, SYN/ACK, ACK) has been essential for establishing web connections, but it is considered too slow for modern requirements. HTTP was designed to be stateless, meaning connections are often closed after use, which can hinder efficiency. 0-RT

Modern speakers rely heavily on digital signal processing (DSP) to achieve high-quality sound, overcoming the limitations of their small size. Traditional speaker design focused on achieving a flat frequency response with minimal artifacts, but today, mobile devices like phones and laptops use software-based DSP techniques such as psycho-acoustic bass enhancement, limiters, and volume-dependent equalization to enhance audio output from tiny speakers. The Asahi Linux project has made significant advancements in improving the audio quality on Apple Silicon MacBooks running Linux. They

Enums in Rust are a popular feature that allows for a type to have one of several specified variants. For example, an enum type `Foo` can either represent an integer (like `Foo::Int(3)`) or a character (like `Foo::Char('A')`). Unlike structs, which combine fields, enums represent an "or" relationship among their variants. The article discusses a surprising optimization made by the Rust compiler regarding the memory representation of enum values. By optimizing memory usage, enums

The translation of C code to assembly via a compiler, like Clang, is complex and not straightforward. To grasp this process, examining LLVM Intermediate Representation (IR) can be helpful, as LLVM IR is a simpler, assembly-like language that organizes instructions and handles values stored in registers. In LLVM IR, straight-line C code translates into a sequence of instructions. Aggregate types (such as arrays and structs) are generally stored in memory, and accessing them requires address computation using the `getelementptr`
