Jesus is the Son of David. So what?
On today's program, the judicial commission of the Anglican Church in North America has handed down its long-awaited verdict in the months-long trial of Bishop Stewart Ruch. And that verdict is, “Not Guilty.” We'll have details. And, International Servants has been making big claims about its decades of ministry work in Belize—but verifying those claims has proven more difficult. We'll take a look. Plus, Elevation Church—the North Carolina-based megachurch led by Steven Furtick—has announced the launch of Elevation College. But first, St. Andrew's Chapel in Sanford, Florida, has officially voted to leave the Presbyterian Church in America. The church, originally led by Dr. R.C. Sproul, joined the PCA in 2023. It first considered a vote to leave this summer, but delayed the vote while referring the matter to the church's board of elders, also known as its session, to study the situation and return with a recommendation. Its lead pastor, Burk Parsons, was suspended from his role as a teaching elder in the PCA in June after being found guilty by a church judicial commission of three charges related to, among other things, a “domineering” and “intimidating” leadership style, which included accusations of bullying and slander. The producer for today's program is Jeff McIntosh. We get database and other technical support from Stephen DuBarry, Rod Pitzer, and Casey Sudduth. Writers who contributed to today's program include Kim Roberts, Kathryn Post, Jessica Eturralde, and Aaron Earls. A special thanks to Lifeway Research for contributing material for this week's podcast. Until next time, may God bless you.

In this episode, I interview Ruthann Anderson, CEO of CAPCA (California Association of Pest Control Advisors). Ruthann explains that CAPCA represents licensed PCAs (Pest Control Advisors) who she describes as “plant doctors,” often recommending non-chemical solutions such as irrigation changes, soil sampling, and nutrition adjustments before turning to pesticides. They advise across agriculture, turf, ornamental, and urban environments, and CAPCA focuses on statewide education and advocacy to support the profession. She discusses challenges like public perception and inconsistent enforcement in the past. A major example is the BeeWhere program, which CAPCA helped modernize to improve communication between beekeepers and pesticide applicators to reduce bee losses, showing how collaboration across groups leads to better outcomes.We also discuss the complexity of pest management, including public health issues like rat infestations, and the misconception that agriculture uses chemicals carelessly. Ruthann mentions grant-funded work documenting over 200 examples of PCAs choosing non-chemical approaches, which CAPCA plans to publish.We also dive into United Ag's mission to transform healthcare in agriculture: simplifying access, reducing costs, and putting empathy first with zero-copay clinics in rural communities. Ruthann highlights how thoughtful decisions, whether in farming or healthcare, lead to better outcomes, and she shares how CAPCA members can leverage United Ag's network for reliable health coverage.CAPCA: https://capca.com/Kirti Mutatkar, President and CEO of UnitedAg.

In this episode, Brandon Pierpont goes beyond ad tactics and shows painting contractors how to turn attention into revenue. Live from PCA's Women in Paint, he breaks down winning Meta ads (CPM, conversion, creative that drives engagement), the “micro-sales” inside your sales process (speed-to-lead, pre-estimate value, selfie confirmations), and the review, referral, and neighborhood-take-rate plays that compound ROI. Practical, no-fluff steps to lower CPL, raise close rates, and build a profitable growth engine.

And we thought they were only connected by wearing LAD caps. But no, Kiké Hernandez apologies to all of Puerto Rico from his hospital bed for having to miss the WBC due to shoulder surgery. Just last week his twin, Prince Harry, was apologizing to all of Canada. PCA and Corbs join Team USA and dear young Pete makes Mr. Judge feel his age. Welcome to little outlaw super athlete child, Josie James Swanson. Turns out our terrible predictions were only a little terrible – we aced Cy Young and the NL! The movement to keep LAD from visiting the White House gains traction, and the aerial tramway to the stadium loses some. The Trop is back and we want to know if the ceiling will still be “where the hell is the ball white.”Baseball United is back, including Barry Larkin Field outside of Dubai, more home grown talent, and some questionable rule changes. The Police Blotter is all sports betting because it is really hitting a new level and we don't miss the irony of the GMs meeting in a casino last week. Preliminary labor talks give Patti her second favorite quote of the week. We crosstrain with the fascist in chief's visit to the Commanders vs Lions game last week and more happily with the PWHL's Takeover Tour. Stay tuned – the WPBL's draft is coming up!We say, “You manifested the orangeness,” “That was putting the camel before the horse,” and, “You could have funded healthcare with that flyover.” Fight the man, send your game balls to Meredith, get boosted, and find us on Bluesky @ncibpodcast, on Facebook @nocryinginbball, Instagram @nocryinginbball and on the Interweb at nocryinginbball.com.

In this episode of Data Skeptic's Recommender Systems series, Kyle sits down with Aditya Chichani, a senior machine learning engineer at Walmart, to explore the darker side of recommendation algorithms. The conversation centers on shilling attacks—a form of manipulation where malicious actors create multiple fake profiles to game recommender systems, either to promote specific items or sabotage competitors. Aditya, who researched these attacks during his undergraduate studies at SPIT before completing his master's in computer science with a data science specialization at UC Berkeley, explains how these vulnerabilities emerge particularly in collaborative filtering systems. From promoting a friend's ska band on Spotify to inflating product ratings on e-commerce platforms, shilling attacks represent a significant threat in an industry where approximately 4% of reviews are fake, translating to $800 billion in annual sales in the US alone. The discussion delves deep into collaborative filtering, explaining both user-user and item-item approaches that create similarity matrices to predict user preferences. However, these systems face various shilling attacks of increasing sophistication: random attacks use minimal information with average ratings, while segmented attacks strategically target popular items (like Taylor Swift albums) to build credibility before promoting target items. Bandwagon attacks focus on highly popular items to connect with genuine users, and average attacks leverage item rating knowledge to appear authentic. User-user collaborative filtering proves particularly vulnerable, requiring as few as 500 fake profiles to impact recommendations, while item-item filtering demands significantly more resources. Aditya addresses detection through machine learning techniques that analyze behavioral patterns using methods like PCA to identify profiles with unusually high correlation and suspicious rating consistency. However, this remains an evolving challenge as attackers adapt strategies, now using large language models to generate more authentic-seeming fake reviews. His research with the MovieLens dataset tested detection algorithms against synthetic attacks, highlighting how these concerns extend to modern e-commerce systems. While companies rarely share attack and detection data publicly to avoid giving attackers advantages, academic research continues advancing both offensive and defensive strategies in recommender systems security.
