Newton Public Schools' 'Equity' Experiment Fails

2024-12-14

In the fall of 2021, Newton Public Schools in Massachusetts implemented a complex initiative called "multilevel classrooms" aimed at improving educational equity. This model mixed students of varying academic abilities into single classrooms with one teacher. Three years later, the results are troubling. Teachers report the model fails to meet the needs of diverse learners; high-achieving students are stifled, while lower-achieving students are hesitant to ask questions. Lack of adequate training and support for teachers led to poor outcomes, with students in multilevel classes often underperforming their single-level counterparts. The school lacked metrics for success, and no data supported the model's efficacy. A teacher's council petitioned to roll back multilevel classes in STEM and world languages, urging the district to find better solutions for addressing educational equity. The failure highlights the need for data-driven approaches and a focus on student needs in educational reform.

Philosophical Dead Ends in Evolutionary Theory

2024-12-15

This review examines Richard Dawkins's "The Genetic Book of the Dead" and Sara Imari Walker's "Life as No One Knows It." Dawkins continues his "selfish gene" theory, arguing that genes are the central driving force of evolution. However, the review points out that this view is outdated and fails to adequately consider factors such as development, epigenetics, and niche construction. Walker's book attempts to explain the origin of life from the perspective of assembly theory, but the review argues that it is overly simplistic and fails to fully clarify the essence of life. The article concludes that popular science books often tend towards simplistic narratives, ignoring the complexity and diversity of the field of biology.

Security Vulnerabilities Stemming from Dart/Flutter's Weak PRNG

2024-12-13

Zellic's research uncovered multiple security vulnerabilities caused by a weak pseudorandom number generator (PRNG) in Dart/Flutter. A flaw in the initialization of the `Random()` function within the Dart SDK resulted in insufficient entropy in generated keys, making them susceptible to brute-force attacks. This allowed attackers to easily gain access to the Dart Tooling Daemon, enabling them to read or write workspace files and even execute arbitrary code. Furthermore, Proton Wallet and SelfPrivacy projects were also affected by this weak PRNG, experiencing encryption vulnerabilities and predictable password issues, respectively. While the vulnerability has been patched, developers are urged to exercise caution when using the `Random()` function and utilize `Random.secure()` when cryptographically secure random numbers are required.
