### Summary
30+
31+
Mastering a subject requires consistent exposure to information, which can be challenging for part-time learners. Spaced repetition systems use flashcards to help retain knowledge, but traditional algorithms can be frustrating due to arbitrary review intervals. A new algorithm, FSRS (by Jarrett Ye), enhances these systems by predicting optimal review times based on the likelihood of recollection. Unlike conventional methods, FSRS applies machine learning to determine intervals tailored to individual recall rates, significantly improving user experience and efficiency in learning, particularly for long-term retention of new information.

The author highlights the improvement of Spaced Repetition Systems (SRS) but points out a gap in tools that facilitate the creation of flashcards from various programs like web browsers and PDF readers. They desire OS-friendly integrations that seamlessly connect to popular SRS programs (like Anki and Mochi), rather than standalone tools. The author is seeking recommendations for such tools that enhance the flashcard creation process without adding unnecessary complexity.

### Summary
46+
47+
Proton, a major VPN and encrypted service provider, plans to exit Switzerland if proposed amendments to the country’s surveillance laws pass. These changes would require VPNs and messaging apps to retain user data, significantly impacting online privacy and encryption. Proton's CEO, Andy Yen, has criticized the amendments as a violation of privacy rights and comparable to Russia's laws. Other companies like NymVPN share similar concerns and are prepared to leave. As public consultations conclude, there’s notable opposition from Swiss political parties and companies regarding the potential legislation.

Proton emphasizes its strong commitment to privacy by implementing non-retention principles, including no logs or trackers. If Swiss privacy laws weaken, Proton may have to relocate to maintain its privacy standards. The real test lies in engineers making choices about their code and hardware in response to changing laws, rather than just public statements from the company.

### Summary
62+
63+
O2 customers have unknowingly exposed their location to call initiators due to a security flaw in the Voice over LTE (VoLTE) system. Research by Daniel Williams revealed that detailed IMS (IP Multimedia Subsystem) signaling messages inadvertently included sensitive data such as IMSI and IMEI numbers, allowing call initiators to track the recipient's location. This vulnerability stems from O2's complex IMS implementation, which has proven problematic. Testing revealed that by using tools like Cellmapper, one could accurately determine a user's location during a call, especially in urban areas where cell coverage is dense.

Efforts to contact O2 regarding privacy concerns were made via email to CEO Lutz Schüler and a Virgin Media address on March 26 and 27, 2025, but no response or resolution was received. The situation is criticized, especially the reliance on a Virgin Media contact. Additionally, the link to O2's security information returns a 404 error instead of the expected 200 status. The author contemplates whether the NCSC might address the issue, given the inaction from O2.

### Summary

79+
Project Verona is developing a new memory and concurrency ownership model called Lungfish for Python. Initially, a prototype language, FrankenScript, has been created to explore region-based ownership concepts through dynamic checks. Key steps include implementing deep immutability to safely share objects between threads, enabling parallel performance without losing the Global Interpreter Lock (GIL). As Python evolves towards a fully concurrent model, this ownership approach aims to simplify concurrent programming. The team is leveraging lessons from languages like Rust while adapting solutions for Python's dynamic nature, preparing for community feedback at the upcoming Python Language Summit in May 2025.

The article explores the efficiency gap between experts and novices, highlighting how novices struggle due to a lack of experience and understanding of the task at hand, often making poor decisions that complicate their problems. The analogy of navigating a maze illustrates this disparity: experts are well-equipped and understand the pitfalls, while novices flounder, even when trying their best. Feedback directed at novices that does not consider their perspective may be unhelpful, suggesting a need for more constructive guidance to aid their improvement in navigating complex tasks.

The article lacks depth, failing to provide specific qualitative or quantitative information about the performance benefits of using Rust with JNI. It suggests that frequent JNI calls can hinder performance and highlights potential issues with garbage collection. The author advocates for structuring unsafe calls into a separate class. Additionally, important details about the `native_add_one` function and the implementation of Tokio futures in Java are missing. Finally, it advises against using ChatGPT for writing, as it complicates the message with irrelevant details.
