This article explains what a Direct Attach Copper (DAC) cable is, how it compares to optical fiber, and the use cases for DACs in data centers. It covers breakout DACs, reach limits, active versus passive DACs, and the cost and compatibility trade-offs of using copper cabling over optics.
General
An in-depth look at modernized techniques for producing the smallest ELF executables on Linux. It details steps from a 383-byte minimal ELF to a 120-byte version via header reductions and code-overlap tricks, and discusses the trade-offs with tool support and debugging. The article serves as a technical exploration of ELF internals and the boundaries of executable minimization.
