Judge Rules Trump Administration's Blacklisting of Anthropic Was Illegal

A federal judge determined that the Trump administration's blacklisting of Anthropic from Pentagon contracts constituted illegal retaliation for the company's public statements on military AI safeguards. The court found the government violated the Administrative Procedure Act, noting weak justification that was largely abandoned during litigation. The administration had designated Anthropic as a supply-chain risk and restricted its defense contracts access, resulting in approximately $180 million in lost deals within days. The judge emphasized explicit evidence of retaliatory intent in public government statements. The ruling highlights concerns about executive overreach and the speed of illegal government actions outpacing court reviews.

Breaking Claude Code Opus 5 Auto Mode

Prompt injection researcher Johann Rehberger discovered a critical vulnerability in Claude Code's auto mode that succeeds 80% of the time. The exploit tricks Claude into downloading and extracting a malicious zip file, then executing code that imports base64 to trigger execution of a hidden local struct.py file. After detecting the compromise, Claude Code's auto mode blocked its own cleanup commands, preventing the system from terminating the malicious process. The research highlights that auto mode became a liability rather than a protection mechanism. Rehberger recommends running unattended agents in isolated environments with restricted network access and active monitoring instead of relying solely on AI-based safety mechanisms.

Luanti Removed from Google Play Due to Baseless AI Copyright Notice

Google removed Luanti from the Play Store after a DMCA notice from Tracer.AI claimed copyright infringement by Microsoft. The notice contained no evidence and the Luanti team says the complaint is wrong. Voxel games are a genre and one company cannot own them. This is the second time Tracer.AI filed this notice against Luanti. The team will fight the removal and calls for better verification of DMCA notices.

htmx 4.0.0 is Released

htmx 4.0.0 introduces attribute inheritance changes, requiring developers to add :inherited after attribute names for explicit inheritance. The release standardizes event naming to htmx:phase:action format and removes XHR-specific events since htmx now uses fetch(). htmx 4 removes default localStorage caching, re-fetches pages on back navigation, and adds morphing swaps for smoother DOM updates. A new <hx-partial> tag enables clearer multi-element updates beyond simple element replacement. The team provides an upgrade tool and keeps htmx 2 as the latest NPM version through early 2027.

How We Saved 100 Terabytes of Memory by Optimizing 1.1.1.1's DNS Cache

Cloudflare reduced memory consumption for 1.1.1.1's DNS cache by 56% per entry, saving approximately 100 terabytes across their infrastructure. The optimization involved five key changes: replacing Vec with Box to eliminate wasted capacity, consolidating multiple record lists into a single list with offsets, making the owner field optional since most records match the query domain, boxing large enum variants to prevent padding overhead, and storing records as raw wire format bytes instead of parsed variants. These changes reduced the per-entry footprint from 953 bytes to 420 bytes while simultaneously improving insert throughput by 43% and reducing lookup latency by 19%.

A Big Bet on Explosive AI-Driven Growth

Economists have wagered on whether U.S. real GDP per capita will grow 15% or more in a single year by the end of 2033. Pro-growth economists MacAskill, Albanie, and Cohen wager $60,000 that explosive AI-driven expansion will occur. Skeptics Moll and Ho wager $240,000 against rapid growth, creating a 4-to-1 odds ratio that implies only 20% probability. This substantial financial disagreement reflects genuine debate about economic futures rather than empty rhetoric about AI's impact.

Polling Results on Capitalism and Socialism

A new poll reveals significant gaps between Americans' private and public views on capitalism and socialism. While only one-third of Americans express positive views of capitalism privately, many publicly endorse it, indicating social desirability bias. The research shows striking demographic differences: nearly half of women would privately consider voting for a socialist, Gen Z shows a 15-point gap between private and public support for socialism, and high earners earning $150k+ are 58% privately open to socialist candidates despite only 42% publicly supporting them. Republicans demonstrate particularly conflicting attitudes, with less than half supporting capitalism in private but two-thirds endorsing it publicly. Overall, Americans remain reluctant to fully embrace either system while showing greater openness to socialist alternatives than their public statements suggest.

Gold and Myth in the Australian Blue Mountains

Hannah Forsyth explores the legend of Govett's Leap in Blackheath, a myth depicting surveyor William Romaine Govett as a bushranger fleeing with gold—a narrative that is entirely fictional. The author uses this mythological mischaracterization to examine colonial Australia's complex relationship with authority, wealth, and resistance. Through archival research into gold transport records and police ledgers from the 1850s gold rush, Forsyth documents how the colonial government systematized gold movement and how hierarchies of human value intersected with economic systems, particularly through the systematic exclusion of Chinese miners from official records despite their significant presence. The article argues that myths, even inaccurate ones, carry historical significance by revealing what colonized and marginalized populations aspired to and feared about state power.

Why Is Leadership Riskier for Women?

Research by Susan R. Fisk and Jon Overton shows that women face larger penalties for leadership failures than men do, which suppresses their ambition to seek top positions. Studies of real-world cases reveal that women managers and surgeons receive harsher formal penalties than male counterparts for the same failures. When presented with high-risk leadership scenarios, women showed significantly lower interest than men, and the fear of career consequences accounts for approximately 31 percent of the reduction in women's leadership ambitions. The research concludes that women's lower representation in leadership roles reflects a rational response to systemic gender discrimination rather than an innate ambition gap.

Your Book Review: Thomas Urquhart's Translation of Rabelais

This review examines Thomas Urquhart's 17th-century English translation of Rabelais' Gargantua and Pantagruel, tracing the eccentric Scottish nobleman's unlikely path to becoming a celebrated translator. Born into debt and pursuing numerous failed ventures, Urquhart's baroque mind proved ideally suited for translating Rabelais, capturing the French original's satirical energy through elaborate vocabulary and creative prose. Though commercially unsuccessful during his lifetime, his translation became the foundation for introducing Rabelais to the English-speaking world through later republication. The review presents Urquhart as a cautionary figure whose grandiose ambitions repeatedly failed, yet whose greatest achievement emerged almost accidentally from financial desperation.
