In this step-by-step guide, we create a fully functional pgvector environment within Google Colab and demonstrate how PostgreSQL can serve as a robust vector database for cutting-edge AI use cases. We begin by setting up PostgreSQL, compiling the pgvector extension from source, establishing connections via Psycopg, and registering vector types to ensure seamless integration with Python. Next, we generate embeddings using SentenceTransformers, store them in PostgreSQL, construct HNSW indexes, and perform advanced operations such as semantic search, filtered queries, comparisons across distance metrics, half-precision storage, binary quantization, sparse vector lookups, hybrid retrieval, and vector aggregation. This hands-on workflow reveals how…

Scientists at Sakana AI and the University of Tokyo have introduced DiffusionBlocks, a new training framework that builds neural networks one piece at a time. Unlike conventional methods that process the entire model simultaneously, this approach cuts training memory usage by a factor of B — where B represents the total number of blocks — while delivering comparable results across a wide range of model designs. Why Memory Becomes a Bottleneck During Training Standard end-to-end backpropagation works by saving every intermediate activation across all layers during a forward pass. Because memory needs increase in direct proportion to the number of…

On Tuesday, May 26, Iran’s vice president confirmed that Internet access was being gradually restored nationwide after nearly three months offline, following the start of U.S. and Israeli military strikes on February 28. Cloudflare Radar data corroborates increased network activity, pointing to a gradual reinstatement of connectivity across Iran. In this article, we’ll walk through key data insights that shed light on this extended blackout — and the encouraging signs that Iranians are slowly regaining online access. As developments continue, Radar will provide up-to-date tracking of Iran’s Internet connectivity status. Iranians have endured two nationwide Internet blackouts this year so…

Don Osborne, CEO of EarthDaily, was traveling to a conference in Colorado when the company’s six newest satellites successfully reached low Earth orbit (LEO) onboard a SpaceX Falcon 9 rideshare mission earlier this month. “The launch itself didn’t worry me much,” he explains. “The real work starts the moment they’re released. You need to track each unit, establish communication, orient them properly, and activate them one at a time. That’s when the pressure really builds.” As more businesses deploy LEO satellite constellations, EarthDaily is among those taking advantage of the growing availability of rideshare launches, mainly from SpaceX and Blue…

  # Introduction  Data is rarely static. Decisions are rarely risk-free. As a data scientist, you are frequently asked to stress-test business assumptions, explore distributional uncertainty, or simulate alternative realities. “What if our daily active user acquisition costs double?” “What if our server traffic spikes by 300% during a promotional event?” “What is the probability that our operational losses exceed $50,000 this quarter?” Answering these what-if questions requires moving from simple point estimates (like the simple mean) to robust, probabilistic thinking. While many practitioners may immediately jump to heavy simulation engines, the standard Python scientific stack already contains an underutilized workhorse…

Key Takeaways A recent research study contends that the phrase “AI psychosis” is an oversimplification of the complex ways chatbots interact with mental health. The team highlights that AI platforms can unknowingly strengthen harmful thought patterns by offering endless approval and emotional support. The study proposes a new term, “existential drift,” to capture how a person’s perception of reality might slowly transform through AI conversations. As artificial intelligence chatbots evolve to be more empathetic, interactive, and customized, experts are raising alarms that these exact features might begin to alter certain users’ grip on reality.A new research paper, titled “Rethinking AI…

Two major banking trojan campaigns affecting users in Latin America and Europe are targeting Windows and Android devices, deploying the Grandoreiro and BTMOB malware families respectively. This comes from recent updates by WatchGuard and ESET, who have identified these two malware variants going after businesses in countries including Spain, Portugal, and Mexico, as well as mobile users in Brazil. According to Euler Neto, a researcher at WatchGuard, the Grandoreiro campaign “employs the DLL Side-Loading technique across four different software applications, focusing on banks located in Portugal.” Grandoreiro has been in operation since 2016 and continues to evolve as a banking…

If you’re running coding agents one after another instead of launching multiple sessions simultaneously, you’re missing a major advantage. One of the biggest strengths of coding agents is their ability to work on several tasks at once—something that wasn’t feasible in traditional software development. But when I fire off many parallel coding sessions, staying on top of everything becomes tricky. You need smart strategies to monitor all active sessions, quickly re-orient yourself when switching between them, and stay productive without losing context. This infographic summarizes the key points of the article. It covers strategies for efficiently managing multiple coding agents…

Terry Gerton Here’s a fun topic to kick off our conversation this morning: disasters. With hurricane season nearly upon us, I imagine you’re already gearing up to collaborate with FEMA on disaster relief efforts. Let’s dive into how contractors actually end up supporting FEMA when a disaster strikes. Stephanie Kostro After all the relentless rain we’ve been dealing with here in the National Capital Region, Terry, it really hits home that hurricane season is right around the corner — and honestly, we’re already in wildfire season too. We’ve seen plenty of wildfires recently, so between the torrential downpours and the…

NTT, Kubota Corporation, and NTT DOCOMO successfully carried out a joint trial (referred to as “the demonstration”) aimed at stabilizing communication and guaranteeing uninterrupted video feeds for remotely operated and monitored robotic farming equipment in hilly terrain. During the demonstration, they applied optimized control to video transmission — essential for operating robotic farm machinery — by integrating mobile and satellite networks alongside video control technology. The results showed that video clarity remained consistent even with variable network conditions, proving the solution’s effectiveness as a communication backbone for remote machinery oversight. NTT plans to showcase this innovation at the Tsukuba Forum…
