Tech Talk Co-Founder Ben Darnell explores PostgreSQL’s unexpected behavior under READ COMMITTED isolation, revealing a tendency to miss rows during certain operations. In contrast, CockroachDB’s approach to READ COMMITTED isolation avoids this issue by implementing a different technique that ensures all rows are correctly updated. Through a detailed comparison of conflicting updates in both databases, […]
C++ Insights is a Clang-based tool that reveals the inner workings of your source code, shedding light on what the compiler does behind the scenes. The tool transforms C++ code snippets into compiler-understandable versions, showing special member functions, casting, and deducing types automatically. Developed by Andreas Fertig, C++ Insights aims to make compiler processes visible […]
Smartphones using magnetic particles in hydrogels and the built-in compass can measure glucose, pH levels, toxins, and other biomarkers for disease detection. NIST researchers demonstrated this technique, allowing for high accuracy glucose measurements using an ordinary cellphone magnetometer. The hydrogels, engineered to react to specific substances, expand or contract affecting the magnetic particles’ distance from […]
