The LangChain ecosystem provides an important set of tools with which to construct an application using Large Language Models (LLMs). However, when the names of the companies such as LangChain, LangGraph, LangSmith, and LangFlow are mentioned, it is often difficult to know where to begin. This is a guide that shows an easy way around this confusion. Here, we will examine the purpose of each of the tools and demonstrate their interaction. We shall narrow down to a practical, hands-on case of the development of multi-agent systems using these tools. Throughout the article, you will be taught how to use…

Since the Model Context Protocol (MCP) was announced by Anthropic a year ago, we’ve seen immense growth in large language models (LLMs) and agentic use cases. Before MCP became the de facto agentic standard, developers building agents on top of LLMs would have to hard-code the connective tissue between the LLM and apps. Developers would need to build custom integrations between their LLM client and the apps required by an end user’s prompt. With MCP, developers can now connect directly with external data sources, so their LLM can read data from and write data to the connected applications. But there’s…

The story you are reading is a series of scoops nestled inside a far more urgent Internet-wide security advisory. The vulnerability at issue has been exploited for months already, and it’s time for a broader awareness of the threat. The short version is that everything you thought you knew about the security of the internal network behind your Internet router probably is now dangerously out of date. The security company Synthient currently sees more than 2 million infected Kimwolf devices distributed globally but with concentrations in Vietnam, Brazil, India, Saudi Arabia, Russia and the United States. Synthient found that two-thirds…

TORONTO — A newly updated guide will help the millions of Canadians who live in condominiums—and those who oversee such properties—overcome the unique challenges that have long limited their access to at-home electric-vehicle (EV) charging. Plug’n Drive and Clean Energy Canada teamed up for Make Your Condo EV Ready: The 2025 Guide for Condo Owners, Boards and Managers, released today. The free guide walks condo building decision-makers through the research, planning, and implementation steps needed to navigate issues such as shared ownership and install EV chargers in their parkades. “A maze of technical, regulatory, governance, and other barriers have long…

Published on: June 27, 2025 Updated on: July 7, 2025Swift 6.2 comes with several quality of life improvements for concurrency. One of these features is the ability to have actor-isolated conformances to protocols. Another feature is that your code will now run on the main actor by default.This does mean that sometimes, you’ll run into compiler errors. In this blog post, I’ll explore these errors, and how you can fix them when you do.Before we do, let’s briefly talk about actor-isolated protocol conformance to understand what this feature is about.Understanding actor-isolated protocol conformanceProtocols in Swift can require certain functions or…

– Advertisement -During the pandemic, the Internet of Things (IoT), which is described as “software, sensors and network connectivity embedded in physical devices, buildings and other items that enable those objects to collect and exchange data and send, receive, and execute commands,” grew quickly. Currently, there are 21.5 billion linked devices on the planet. According to the World Bank’s Findex 2021 survey, 1.4 billion persons still lack access to banking, with women making up the majority. Additionally, 850 million individuals worldwide lack any kind of ID, let alone a digital one. This offers the chance to skip ahead to a…

Androidify transforms your selfie photo into a playful Android bot using Gemini and Imagen.However, given that Android spans multiple form factors, including our most recent addition, XR, we thought, how could we bring the fun of Androidify to Wear OS?An Androidify watch faceAs Androidify bots are highly-personalized, the natural place to showcase them is the watch face. Not only is it the most frequently visible surface but also the most personal surface, allowing you to represent who you…

From a theoretical perspective, ion transport through micrometer or nanometer-sized pores under a cross-pore electric field can be described well by the Hall equation, involving only the bulk conductivity, if the solution is not too dilute. For dilute solutions, it is predicted that the surface conduction will become important, especially in nanopores. Nonetheless, this remains unsupported by experiments, especially for micropores, where the experimentally observed ion conductance is intuitively thought to be dominated by bulk conduction. Herein, our electrical measurements of ion transport through silicon nitride pores having diameters ranging from sub-µm up to a few µm show that the…

Enterprises are making faster progress with agentic AI than many expected, not because the tooling is mature, but because companies have realized they can’t afford to wait. The leading 10 to 20% of organizations are racing ahead, standing up internal “agent platforms” that handle planning, tool selection, long running memory, workflow coordination, and human in the loop approvals. Capabilities they once assumed off the shelf copilots would provide. They aren’t trying to become orchestration framework vendors; they’re filling gaps because enterprise needs for reliability, auditability, and policy enforcement are higher than what the current ecosystem offers. Yet despite these limitations,…

In any engineering organization, management of communication among the stakeholders is a key challenge. The more extensive the complexity and scope of the endeavor, the greater the need to communicate. From senior leadership to the shop floor, communication is key. Digital engineering transformation is increasingly driving the methods and the means to improve how we share information.In November of 2024, the SEI brought together stakeholders from the Department of Defense and the intelligence community (IC) who have been engaging and actively innovating in the dynamic environment of digital engineering. Our workshop focused mostly upon model-based systems engineering (MBSE) as a…
