The piece discusses the historical and mathematical intrigue surrounding tetrahedra, geometric shapes with four triangular faces, initially categorized by Plato in 360 BCE. Despite their simplicity, puzzles involving tetrahedra remain unresolved, such as questions regarding their packing density and their ability to be chopped into pieces that can form a cube. A significant inquiry involves whether a tetrahedron made of uniform material can be designed to only rest on one face, termed a “monostable” shape. Mathematicians John Conway and

The author discusses the use of `dynamic_cast` in C++ and generally advises against it due to its negative impact on code readability. However, they acknowledge there are situations where using `dynamic_cast` may be justified, particularly in SDKs that evolve over time with versioned interfaces to maintain compatibility. In the example provided, SDK owners use versioning to prevent user code from breaking. They retrieve a basic pointer type (like `void*`) from a DLL, then attempt to cast it to

The article discusses accessing the NFC chip data in a passport using Linux, specifically with a tool called pypassport. The NFC chip, which stores passport information including biometrics, is secured by a password located in the Machine Readable Zone (MRZ) on the passport. This password comprises three data pieces, each with its own checksum, and the entire string also has a checksum, which can be partially lost if the passport is canceled by cutting the MRZ. The author faces a challenge since using

The content discusses the differences between improvisational creativity in jazz and structured processes in software development, particularly in modeling sessions. It highlights a phenomenon referred to as “the CTO effect,” where the first person to speak—often a senior leader—dominates the discussion, causing quieter team members to lose their voices. To counteract this, the author recommends starting modeling sessions with 10-15 minutes of silent brainstorming. This allows all team members to generate ideas simultaneously, preventing any single individual from steering the conversation
