Xdelta [3] is a command line tool for delta encoding, which stores or transmits the difference (deltas) between sequential data, instead of entire files.This is similar to diff and patch, except diff computes and shows the difference between two complete files, while patch is primarily designed for human-readable text files; Xdelta is designed for binary files and does not generate human ...
A software license is a legal instrument that governs the usage and distribution of computer software. [1] Often, such licenses are enforced by implementing in the software a product activation or digital rights management (DRM) mechanism, [2] seeking to prevent unauthorized use of the software by issuing a code sequence that must be entered into the application when prompted or stored in its ...
One can implement a key generator in a system that aims to generate, distribute, and authenticate [4] keys in a way that without the private key, one cannot access the information in the public end. [5] Examples of key generators include linear-feedback shift registers (LFSR) and the Solitaire (or Pontifex) cipher.

Delta’s lawsuit filed in Fulton County Superior Court called the faulty software update from CrowdStrike “catastrophic” and said the firm “forced untested and faulty updates to its ...
Software crack illustration. Software cracking (known as "breaking" mostly in the 1980s [1]) is an act of removing copy protection from a software. [2] Copy protection can be removed by applying a specific crack. A crack can mean any tool that enables breaking software protection, a stolen product key, or guessed password. Cracking software ...
Google refers to delta updates as "smart updates." This has been implemented in Google's Android operating system devices that run on Android 2.3 or above. Google engineers have estimated that smart updates would be only about one third the size of a full update on average.
Software development tools inspired by delta debugging include the bisect commands of revision control systems (e.g., git-bisect, svn-bisect, hg-bisect, etc.), which, instead of working on the program's code, apply the delta debugging methodology on the code history by comparing various versions until the faulty change is found.
