New open-source Java library ChaosTree offers AVL, Red-Black, B-Tree and B+ Tree structures

A developer released ChaosTree, a zero-dependency Java library implementing multiple sorted-tree data structures—AVL, Red-Black, B-Tree, and B+ Tree—with Set and Map APIs modeled on JDK's NavigableSet, NavigableMap, SequencedSet, and SequencedMap interfaces. It also includes specialized bulk-construction methods like buildFromSorted and importFlatMatrix that let developers tune node occupancy directly.

UF Frat 'Fort' Linked to Viral Nonconsensual Video, Spread via X and YikYak

University of Florida sophomore Maddie Kowalski learned a sexually explicit video of her, filmed inside a Phi Delta Theta fraternity house known as 'Fort,' was circulating online. The footage spread rapidly across Snapchat, the anonymous app YikYak, and was posted publicly on X by an anonymous account that named her and her sorority, prompting a wave of mockery and harassment from students.

A Shizuku fork fixes its biggest flaw: apps stop dying in the background

Android Authority highlights an open-source fork of the popular Shizuku app that solves its most persistent problem — failing to stay active in the background and not restarting after a device reboot. Because Shizuku grants other apps access to restricted system APIs, its instability has long forced users to manually relaunch it, breaking tools like uninstallers and adaptive theme switchers. The fork, built by developers working from Shizuku's GitHub repository, adds automatic recovery so dependent apps keep working without manual intervention.

Y Combinator's Garry Tan Opposes Crackdown on AI Model Distillation

Amid accusations that Chinese firms like DeepSeek and Moonshot AI distilled outputs from OpenAI and Anthropic models, U.S. security agencies issued a joint advisory warning about the practice. Y Combinator CEO Garry Tan pushed back, arguing regulators should avoid restricting distillation and instead focus on balancing open-weight and frontier AI models, while suggesting smaller U.S. labs use similar techniques on domestic frontier models.

Towns dropping Flock license-plate cameras still can't erase stored surveillance data

Local governments nationwide, from Florida to Washington state, are terminating contracts with Flock Safety amid public backlash over its AI-powered license plate readers. However, ending these agreements doesn't guarantee immediate camera removal or deletion of previously collected data, since contract terms vary widely on data retention after termination.

Essay Argues Roundabouts Beat Traffic Lights as Traffic-Control Design

A software engineer published an essay comparing roundabout intersections to traffic-light systems, arguing that roundabouts solve common traffic problems—like sensor failures for bicycles or motorcycles and drivers racing through yellow lights—without any electronics or moving parts. The piece contends that roundabouts naturally slow traffic and only cause delays when genuinely necessary, unlike signal-based intersections that can create unnecessary waits or false negatives.

Microsoft confirms September patches break Remote Desktop Services on Windows Server

Microsoft has verified that its September 2026 security updates are causing Remote Desktop Services failures across Windows Server 2012 and later, plus Windows 10 and 11. Affected systems show RDP connections dropping after a few minutes, sign-in errors, servers stuck loading the Remote Desktop Configuration screen, and related tools like MMC and File Explorer becoming unresponsive.

Sanders and Casar propose bill banning superintelligent AI with 20-year prison penalties

Senator Bernie Sanders and Rep. Greg Casar introduced the Ban Artificial Superintelligence Act, which would permanently prohibit building or deploying superintelligent AI and temporarily halt advanced AI development until federal safety rules exist. The bill also calls for a new cabinet-level agency to monitor AI systems for dangerous capabilities and pursue international agreements against superintelligence development worldwide.

Cohere CEO Aidan Gomez warns against letting Big AI firms set global safety rules

In a new opinion piece, Cohere co-founder Aidan Gomez argues that a small group of dominant Silicon Valley AI companies should not be allowed to single-handedly write the safety standards and competition rules governing artificial intelligence worldwide. He acknowledges AI carries real risks, citing Cohere's own work deploying systems in banks, telecoms and defense ministries, but insists the real debate is about who gets a seat at the table in shaping oversight, not whether oversight is needed.

Nike dropped from S&P 100 after losing $200 billion in market value

Nike will be removed from the S&P 100 index on September 21, ending an 18-year run, as its market capitalization has fallen from a 2021 peak of $264 billion to about $57 billion today. The sportswear giant remains in the broader S&P 500, but its removal from the top-100 index reflects a sustained decline, including a 36% drop in market cap in 2026 alone. Honeywell Aerospace, Simon Property Group and Colgate-Palmolive are also exiting the index the same day, replaced by tech firms like Dell, Palo Alto Networks, Arista Networks and Sandisk.
