Lobsters·1yWhy do we call it "boilerplate code?"
The term 'boilerplate code' originates from the Industrial Revolution, combining aspects of steam engine boilers and the Linotype machine used in hot metal typesetting. Boiler plates referred to uniform, rolled sheets of iron used in steam engines. With the advent of hot metal typesetting, easily replicable molds of text made it possible for standardized articles to be distributed to various newspapers, which led to the use of 'boilerplate' to describe unoriginal, standardized content. This term was later adopted in journalism, law, and eventually programming to refer to repetitive or standard sections of code.
Lobsters·1yWhy Golang slices still surprise me
Golang slices have dual behavior, acting as either dynamically sized arrays or fat pointers, which can cause confusion and bugs. Dynamic arrays own their data, while fat pointers do not, making some operations like appending invalid depending on the context. The capacity field in slices introduces surprising behaviors like reslicing beyond the length and modifying capacity, contradictory to Go's minimalist philosophy.

Lobsters·1ySoftware Design is Knowledge Building
A company relies on an integration service but decides to build an in-house system to cut costs. Despite successful initial development, the system becomes hard to maintain when transferred to a new team. This is attributed to the lack of a shared mental model among the new developers, making it difficult to understand and modify the software. The post highlights the importance of knowledge building and proper documentation in software design to ensure long-term maintainability.
Lobsters·1yTuring Machines
David Hilbert's 1928 Entscheidungsproblem asked whether an algorithm could determine the correctness of mathematical statements, to which Alan Turing and Alonzo Church independently concluded 'no' by 1936. Turing's hypothetical 'universal machine,' later termed the Turing machine, is foundational for modern CPUs, demonstrating that all computations can be boiled down to basic instructions. Programs for Turing machines can perform tasks as simple as printing sequences or as complex as arithmetic operations, reflecting the principles of modern computing. Despite their theoretical nature, Turing machines underpin the concept of 'Turing completeness,' crucial for understanding computational boundaries and the essence of modern computers.
