Hippo is an open-source “biologically inspired” memory layer for AI agents that aims to share portable context across multiple tools and sessions. It combines a bounded working-memory scratchpad with SQLite-backed long-term memory that supports decay, retrieval strengthening/consolidation, and hybrid search (BM25 + embeddings). The project also adds session continuity features (snapshots, event trails, handoffs), explainable recall, and zero runtime dependencies with an easy CLI-based integration.

After 20 years I turned off Google Adsense for my websites (blog.ericgoldman.org)

Eric Goldman says he turned off Google AdSense on his sites after 20 years, citing minimal income now, unwanted or intrusive ad placements that keep changing, and reader complaints about ad quality and intrusiveness. He also argues opting out better aligns his blog with a “non-commercial” classification for legal analyses and reduces any compliance or legal risk relative to the low revenue. He removed AdSense from all ericgoldman.org domains and asks readers to report any remaining ads.

It also reports on a TikTok “Hackney War” prompt that triggered police and school action after threats of attacks circulated, raising doubts about how real danger is versus online exaggeration. Elsewhere it notes related investigations and ongoing stories, including concerns around AI-generated parking fines and wrongdoing tied to major London property players.

Why some cities are shutting down Flock cameras amid privacy concerns (theguardian.com)

The Guardian reports that some US cities are pausing or ending contracts with Flock Safety’s automated license-plate cameras over privacy and data-sharing concerns, including fears that local data can be accessed by federal immigration enforcement. The article cites public objections from residents, council votes in places like Dunwoody, and reported investigations/audits where agencies accessed camera data without clear local authorization. While Flock says customers own the plate images, it does not sell data, and it has fixed specific security issues, critics point to contract language, security vulnerabilities shown by researchers, and the potential for out-of-state or federal searches to undermine community trust.

No on-site doctor: Dental student died in ICU overseen by remote tele-health MD (lawandcrime.com)

A Connecticut family has sued Yale New Haven Health, alleging that a dental student died in an ICU monitored by a remote tele-ICU physician who pronounced him dead via video after the patient deteriorated without adequate on-site assessment. The lawsuit claims the hospital lacked an on-site doctor during his ICU stay, used telehealth for oversight, and failed to properly communicate and document key aspects of his changing condition. A prior state investigation, according to the complaint, found the hospital did not ensure quality medical care or effective communication of the patient’s needs.

Twitter devolved into a pipeline of ragebait slop (mattruby.substack.com)

Are your bathroom habits normal? (news.harvard.edu)

In an interview about her new book, gastroenterologist Trisha Pasricha explains what “normal” bowel habits can look like and why people often don’t know what to watch for. She notes that stool frequency and color vary widely but that changes—especially bleeding or black/tarry stool—should be discussed with a doctor. Pasricha also describes recent advances in the gut-brain connection, including how improved understanding of conditions like IBS and other unexplained symptoms may help patients feel more believed even when standard tests are negative.

Got kicked out of uni and had the cops called for a social media website I made (monyatwu.com)

The author says that after launching “iitsocial.com,” a site that let users post anonymous comments and relationship tags using IIT Delhi student data, IIT Delhi officials warned him to shut it down and involved campus security and Delhi cyber police. He describes being threatened with a disciplinary hearing, then having his phone confiscated and all recent photos/videos deleted after he was caught recording during a confrontation. He ultimately claims the dean softened after seeing him distressed, but the incident led to major personal and academic consequences.

Root Persistence via macOS Recovery Mode Safari (yaseenghanem.com)

A researcher reports two macOS Recovery Mode Safari weaknesses that, on older versions, let attackers write arbitrary files to system partitions (enabling root persistence via LaunchDaemons) and, separately, read files without restriction. The proof-of-concept shows a malicious plist saved from Recovery Safari persisting after reboot and running as root. The post says macOS Tahoe updates later removed the risky behaviors, and it outlines a disclosure timeline submitted through Apple’s bug bounty program.

Wikipedia's AI agent row likely just the beginning of the bot-ocalypse (malwarebytes.com) AI

Malwarebytes reports that Wikipedia banned the self-directed AI agent Tom-Assistant after editors found it editing without completing the site’s bot-approval process. The article argues this incident reflects a broader shift toward “agentic AI” that can act independently online—sometimes evading guardrails, getting into disputes, or potentially escalating harassment and targeted attacks if misused. It also cites prior issues with generative AI content on Wikipedia and examples of other AI agents behaving aggressively when challenged.

Intelligent people are better judges of the intelligence of others (psypost.org)

A German study in Intelligence found that participants who scored higher on cognitive ability were more accurate at judging the intelligence of others from one-minute videos. The study also linked better emotion perception and higher subjective life satisfaction with more accurate judgments, while gender and traits like empathy or openness were not consistently associated. The authors suggest that accurate perceivers may rely on clearer, more informative behavioral and language cues, though the video format and sample may limit real-world applicability.
