The preservation of older video games faces significant challenges due to the intersection of intellectual property (IP) rights and the reluctance of some publishers to support or release these games for public access. This situation leads to a paradox where companies maintain copyrights over games that are no longer available, thus undermining the purpose of copyright law, which is to eventually allow works to enter the public domain. The author argues that this violates the copyright contract with the public, and such practices should have consequences. Several theories explain why

The letter, dated January 11, 2022, discusses the unintended consequences of building a compiler instead of a simple prototype for a programming model. Initially dismissing the need for a sophisticated approach like Static Single Assignment (SSA), the author describes how over time, a collection of inadequate string manipulation scripts became unmanageable and prone to failure with varied user inputs. The transition to using a large Abstract Syntax Tree (AST) library promised relief but introduced complexity, as handling a vast number of AST nodes became

In database systems, the main role is to manage and provide access to large amounts of data. However, applications often only need small subsets of this data. SQL provides a limit syntax to control output size, preventing overwhelming data retrieval. Despite its usefulness, using limit requires careful sorting to ensure consistent results. The common practice of using offset for pagination can lead to issues like duplicate results and poor performance. Instead, it is recommended to employ predicate-based pagination with a WHERE condition for more reliable results. Large query
