Unity Store Bans VLC Plugin, Highlighting Open Source Sustainability Issues

2025-05-07

Since December 2019, Videolabs has offered an open-source VLC for Unity integration plugin via the Unity Asset Store. However, in late summer 2023, Unity unexpectedly banned their publisher account, citing the inclusion of LGPL code, refusing reinstatement even after offering to remove all LGPL code. This highlights the precarious existence of open-source maintainers, especially considering Unity itself relies on LGPL libraries. To continue serving users, Videolabs launched its own store, offering the VLC for Unity plugin and consulting services for LibVLC and FFmpeg, emphasizing the need for sustainable open-source project models.

Large Soda Lakes: A Phosphorus-Rich Cradle of Life?

Large Soda Lakes: A Phosphorus-Rich Cradle of Life?

Phosphorus, essential for life, is relatively scarce on Earth's surface. New research suggests large, endorheic soda lakes may have provided early life with sufficient phosphorus. These lakes lose water only through evaporation, leading to phosphorus enrichment. Mono Lake in California serves as an example, its high phosphorus concentration supporting diverse organisms. Contrary to Darwin's speculation, large soda lakes, with their consistently high phosphorus levels, may have been more conducive to the chemical reactions necessary for life's origin.

Bluesky Improves Performance with 'Lossy Timelines'

2025-02-19

Bluesky tackled database hot spots caused by high-activity users by introducing 'Lossy Timelines'. This mechanism probabilistically drops write operations, limiting the load from heavily followed users and dramatically reducing P99 latency. Write operations that could take minutes now complete in under 10 seconds. This strategy cleverly sacrifices some data consistency for massive gains in system performance and scalability, demonstrating that imperfect system design can lead to a better user experience in specific contexts.

Art-Inspired Discovery: The Third Kind of Magnetism

Inspired by M.C. Escher's artwork, physicist Libor Šmejkal predicted and confirmed a third type of magnetism – altermagnetism. Unlike ferromagnetism and antiferromagnetism, altermagnets have atomic magnetic moments pointing in opposite directions but with a 90-degree rotation, resulting in unique quantum properties. This new magnetism promises to solve challenges in spintronics, leading to more efficient and faster computer memory. Researchers have confirmed altermagnetism in manganese telluride and are exploring more such materials, even predicting a fourth type: antialtermagnetism.

Senior Software Engineer Sentenced for Sabotaging Employer's Systems

Davis Lu, a 55-year-old senior software developer, was found guilty of sabotaging his former employer Eaton Corporation's systems and faces up to 10 years in prison. Before his departure, Lu developed malicious software that locked thousands of employees out of the network, causing significant financial damage. Investigators discovered Lu created malware named "Hakai" (Japanese for destruction) and "HunShui" (Chinese for sleep), along with a "kill switch" that locked all accounts upon his access revocation. He also attempted to delete company data and operating system directories. Despite admitting to the actions, the jury found Lu guilty of intentionally damaging a protected computer.

Trump's Tariffs: A Protectionist Repeat of History

Trump's latest round of tariffs has sparked reflection on the history of US protectionism. The article uses the US shipbuilding industry as a cautionary tale, showing how protectionist policies stifle innovation and lead to industry decline. From the Tariff Act of 1789 to today, the US repeats the same mistakes; high tariffs haven't protected domestic industries but increased consumer costs and harmed US competitiveness. Experts warn this will particularly hurt the clean energy sector, reliant on imported components. Ultimately, protectionism hinders innovation and backfires.
