1US Court nullifies FTC requirement for click-to-cancel
- The 8th Circuit rejected FTC's implementation of the Negative Option Rule, ruling that the agency failed to conduct required preliminary regulatory analysis for rules exceeding $100M impact. The court found this denied stakeholders proper time to review and comment on cost-benefit analyses.
FTC procedural failure
Court ruled against FTC's click-to-cancel rule because FTC failed to conduct required analysis for rules with >$100M economic impact, despite being warned. Debate over whether this was legitimate procedure or technicality favoring business.European vs US consumer protection
Discussion contrasts stronger EU consumer protections with weaker US system, though some note EU rules created cookie banner issues. US system seen as hampered by regulatory capture and congressional dysfunction.Subscription cancellation difficulties

2Tree Borrows
- Tree Borrows is an improvement over Stacked Borrows in Rust's memory safety system. It uses a tree structure instead of a stack to better handle unsafe code patterns while maintaining optimization capabilities. The new approach reduces rejected test cases by 54% when evaluated across 30,000 Rust crates.
Tree borrows vs C aliasing
Extensive discussion comparing Rust's Tree Borrows approach to C's strict aliasing rules. Consensus is that Rust's model is cleaner, more useful and less problematic than C's type-based aliasing, though real performance impact remains debated.Specification of unsafe rules
Discussion of how Tree Borrows helps formally define the boundaries of undefined behavior in unsafe Rust code, particularly around pointer aliasing, which has previously lacked precise specification.Borrow checker implementations
Debate about having multiple borrow checker implementations with different characteristics. Most argue this would fragment the ecosystem, noting Rust already supports switching implementations as they improve.
3Smollm3: Smol, multilingual, long-context reasoner LLM

5Linda Yaccarino is leaving X
- Linda Yaccarino announced her departure as CEO of X (formerly Twitter) after serving for two years under Elon Musk's ownership. Her exit follows significant changes at the company, including staff reductions and recent business restructuring where X was sold to Musk's AI company xAI in a stock deal.
CEO's impact and power
Discussion around whether Yaccarino had any real power as CEO, with most agreeing she was ineffective but debating if the company's 80% valuation drop was her fault or Musk's, given her limited authority.Platform resilience
Despite brand damage under Musk's ownership and X rebrand, the platform remains relevant due to network effects. Users note declining quality but acknowledge difficulty in migrating to alternatives.Corporate dynamics
Debate over whether Musk's Twitter takeover was successful, with arguments about platform sustainability, value of massive layoffs, and whether serving political aims justifies financial losses.
6Most RESTful APIs aren't really RESTful
- The dissertation by Roy Fielding introduces REST as an architectural style for network systems, emphasizing scalability and maintainability. He criticizes the oversimplification of REST in modern APIs, particularly regarding CRUD operations, and stresses that true RESTful APIs must be hypertext-driven with proper implementation of HATEOAS principles.
Rest vs modern practice
Modern REST APIs typically use JSON, map CRUD to HTTP verbs, debate status codes, and often modify endpoints for filters - diverging from Fielding's original vision but becoming an accepted industry standard.Hateoas practicality
HATEOAS adds unnecessary complexity for most APIs and lacks practical value except in specific cases like public APIs. Most developers prefer direct endpoint documentation over runtime discovery.Client-server coupling
Moving coupling from URL structure to document structure doesn't solve fundamental API design challenges. Clients still need to understand API semantics regardless of where that information is stored.
7Bulgaria to join euro area on 1 January 2026
- The Council of the EU has approved Bulgaria's accession to the euro area on January 1, 2026, with a fixed conversion rate of 1.95583 lev per euro. Bulgaria joined ERM II in 2020, and the ECB has been supervising Bulgarian banks since October 2020.
Euro adoption effects on national economies
Debate over whether joining Eurozone helps or hurts developing economies, with focus on monetary policy control, inflation risks, and borrowing costs. Some argue it reduces sovereignty while others cite benefits like lower interest rates.Historical Euro implementation experiences
Discussion of previous Euro adoptions in different countries, particularly regarding price changes and inflation during currency transition. Mixed reports on whether prices doubled or just experienced minor rounding adjustments.Bulgaria's specific situation
Bulgaria's Lev has been pegged to Euro for years through currency board, making practical impact minimal. Focus on symbolic importance and potential economic benefits/risks of full Eurozone membership.
8Astro is a return to the fundamentals of the web
