Gimlet Labs has closed a $300 million Series B funding round led by Andreessen Horowitz, with participation from Sapphire Ventures, Menlo Ventures, Arm, Samsung Ventures, Tiger Global and others. The company says it has added billions in contracted revenue and gigawatts of datacenter pipeline since March, and is scaling toward hundreds of megawatts of managed capacity, just five months after its Series A.
IEEE Computer Society published an interview with database expert Vinodkrishna Gopalan on how relational databases must evolve to handle AI and machine learning demands. The discussion centers on how AI workloads—marked by large scans, unpredictable queries, vector search, and low-latency inference—differ from traditional transactional database use cases, requiring new approaches to schema design, indexing, and scaling.
A technical essay argues that describing large language models as mere next-token predictors is outdated once reinforcement learning with verifiable rewards (RLVR) enters the picture. Unlike pre-training, which only reinforces sequences already present in training data, RLVR lets models generate novel token sequences and learn from evaluating their outcomes. The piece walks through pseudocode contrasting the two training loops to show how post-training changes what the model is actually optimizing for.
An Entrepreneur contributor argues that while AI coding agents have been rapidly embraced by software teams, autonomous agents for go-to-market functions like sales and marketing remain underused. The piece attributes this gap not to AI capability limits but to fragmented, duplicated sales data that lacks connection to reliable external signals needed for commercial decisions.
A newly launched smart toothbrush priced at $499 uses AI-driven sensors to guide brushing technique and claims it can reduce the need for manual flossing. The product enters a growing category of connected oral-care devices aimed at improving dental hygiene compliance through real-time feedback.
Candidates across parties are campaigning against Flock Safety's AI-powered license-plate camera network, which operates in thousands of U.S. communities and lets police search shared vehicle data. Politicians in Wisconsin, Pennsylvania, Michigan and Florida have called for bans, funding cuts, warrant requirements, or campaigned directly against the surveillance system. Flock defends the technology, citing its role in solving roughly a million crimes and reuniting thousands of missing people with families.
Jacob Stokes, a former Obama national security official now at the Center for a New American Security, published a report titled 'Superpowers and AGI' urging the US to prepare drastic responses if China reaches artificial general intelligence first. His proposed options range from cyberattacks to sabotage AI systems up to kinetic military strikes on physical data centers, which he acknowledges carries the highest risk of escalation.
US military branches confirmed to Senator Ron Wyden and Reuters that they have turned off advertising identifiers on service members' phones and computers. The Air Force disabled them two months ago, Special Operations Command did so recently, and the Army says mobile ad IDs have been off since earlier this year, with Windows devices blocked since before 2021.
A Denver resident filmed a newly built AI data center running its lawn sprinklers heavily enough to create standing puddles, even as Denver Water's Stage 1 drought restrictions limit residential and commercial lawn watering to twice a week through September, with a full ban starting October 1. The footage went viral and fueled anger, though it remains unclear whether the facility violated the rules, since the timing of the video, use of recycled non-potable water, or a special variance could all justify the watering.
The Army, Air Force, Navy, Marine Corps and Special Operations Command have all turned off advertising tracking on government-issued phones and computers, according to a letter Senator Ron Wyden shared. The change, rolled out earlier this year with the Air Force following in July, blocks the advertising identifiers apps use to generate location data that gets sold to data brokers.
IDScan, an identity verification firm used by rental car companies, retailers and other businesses, faces multiple lawsuits after a dark-web service called Nexus allegedly offered access to over 153 million U.S. and Canadian driver's licenses along with millions of other ID documents. Journalist Brian Krebs traced the leaked data back to IDScan, and the FBI's New Orleans office has reportedly opened an investigation. IDScan has not confirmed a breach occurred or commented publicly on the allegations.
The database maker Spacetime published a detailed breakdown of how it handles scaling, arguing that scalability splits into three separate dimensions: compute, storage, and networking. It says horizontally scalable storage is coming October 31, 2026, while networking and computation cannot always be scaled horizontally, especially for OLTP workloads with contending transactions.
