Hackernoon

11 September 2026 It’s late in the night. The espresso cup didn’t provide the alertness I was hoping for. I’m struggling to find the proper words to present my app in another Reddit post. Suddenly my phone lights up and interrupts me mid-sentence. I furiously pick it up and I stop in disbelief. Levely has … Read more

An observability-first approach for building an AI agent, and what it bought me. A couple of weeks ago I started implementing Kept, a self-hostable post-purchase support agent for e-commerce, with reliability as its core offering. Besides the product itself, my objective in building it is to delve into the depths of agentic system design, and … Read more

This post’s title may seem odd to you, if you’re up to date, but a few things have changed from React 18 to 19, and one of them is how you manage document metadata. Before it, you likely had some shenanigans going on, like react-helmet or react-helmet-async in place to dynamically update your document title, … Read more

Oura’s competitors fall into three groups, according to its IPO prospectus: smartwatch makers such as Apple, Google and Samsung; fitness wearables such as Garmin, Coros and Whoop; and software-only health apps. In smart rings, Oura is far ahead, with about 74% of global shipments in the first half of 2025, research firm Omdia estimates. OURA … Read more

Key Takeaways Legacy search clients like elasticsearch==7.10.1 hard-cap underlying transport libraries (urllib3<2), blocking critical security patches for vulnerabilities like CVE-2025-50181. elasticsearch-py 7.14.0+ introduced a client-side UnsupportedProductError check that refuses connections to non-Elasticsearch servers, making opensearch-py the necessary drop-in for AWS OpenSearch domains. Upgrading to opensearch-py alone does not guarantee a security fix because its urllib3 … Read more

A few months back, I was pulled into a call that started with someone staring at a Databricks bill and asking, quite genuinely, “did we get hacked?” We hadn’t. What had happened was far more mundane and, honestly, far more common: a retrieval-augmented pipeline feeding a set of agents had quietly tripled its token consumption … Read more

A drafted support reply usually gets one round of scrutiny before it goes out, usually by the same person who wrote it, in a hurry. Tone problems, unauthorized promises, and replies that should have gone to a manager first tend to surface later, in a QA pass, well after the message is already sent. Most … Read more

Six of the 39 were severity-1. Not one was a payment bug. I run scvd.store, a small storefront where the customers are AI agents and the money is USDC over x402. Between September 5 and 8, I pointed Codex at my own live checkout and gave it one instruction. Not “find bugs.” Something narrower and … Read more

If you’re running a React Router app in framework mode, you get SSR out of the box and for production it hands you @react-router/serve, a small server built on top of Express. While it does the job, Express carries a bit of history (and weight) with it, so if you’re the kind of person who … Read more

A support leader I spoke with recently was comparing two quotes. One vendor wanted $85 per seat per month. Another wanted $0.99 per resolution. She was doing the obvious arithmetic: 99 cents is cheaper than 85 dollars, so the AI agent is basically free. A few months later her AI line item was larger than … Read more

Introduction: AI Without the Integration Nightmare For years, building AI-powered applications meant cobbling together a patchwork of specialized systems. You had your relational database for transactions, a vector database for embeddings, a separate service for full-text search, and maybe a graph database for relationships. The data fragmentation was real, and as DBAs, we bore the … Read more

Most AI systems on the market right now have one main job: creating stuff. They pump out text, summarize massive PDFs, or write code, token by token. But it’s the wrong tool for the countless micro-decisions that have to happen before any actual generation begins. Things like: Which files actually matter here? Where should we … Read more

Artificial intelligence is no longer just changing how films are marketed, edited, or distributed. It is beginning to reshape the entire production pipeline itself. From micro-drama production to filmmaking, where budget, resources, and creative iteration often determine whether a project can move forward, AI is becoming more than a tool. It is becoming part of … Read more

The autonomous AI coding agent era is not a futuristic projection mapped out on a startup’s pitch deck. It is here today—measured in millions of production sessions, verified by peer-reviewed benchmarks, and actively restructuring how engineering teams in the world’s largest technology companies think about software delivery. For the past three years, the tech industry … Read more

Collecting logs is easy. Using them effectively during a production incident is much harder. In a distributed system, a single user request may pass through several services, Kubernetes pods, network layers, databases, queues, and external dependencies. When something starts failing, engineers can quickly find themselves searching through thousands or millions of log entries without knowing … Read more

A language model returns text that is usually the shape you asked for. A mobile interface needs data that is always the shape it can render. That gap — between a probabilistic response and a deterministic UI — is where most AI features quietly break in production. The fix is not a better prompt. It … Read more

Varonis Threat Labs discovered AvisLoader, a new Windows malware loader built to keep its command-and-control (C2) channel beyond the reach of traditional domain takedowns. Varonis Threat Labs recently discovered AvisLoader, a new Windows loader named after the Latin word for bird. We found it on an exposed staging server alongside a ClickFix lure, supporting tools, … Read more

Every speech-to-text vendor claims to be the most accurate, and most of them have a benchmark that says so. Usually their own. Meanwhile, the field is racing to shave another 20 milliseconds off finalization, and every release gets announced as a win. If you are choosing a model for a voice agent, there’s a lot … Read more

Bybit lost $1.5 billion in February 2025 when the people approving a routine transfer signed a transaction whose real destination was not the one on their screens, according to Chainalysis. In December a single trader lost $50 million by copying an address from his own transaction history that an attacker had planted there. Another lost … Read more

Gartner predicts that 33% of enterprise software applications will include Agentic AI by 2028, up from less than 1% in 2024. As agentic capabilities move beyond isolated AI experiments and into business-critical workflows, this shift also transforms the Agentic mobile app development paradigm. But even as artificial intelligence becomes mainstream, confidence in it is still … Read more

A code block written by hand is pretty simple: use the ‘pre’ and ‘code’ HTML elements, and the browser gives you a monospace font and keeps your line breaks, but it stops there. So every keyword, string, comment, and variable comes out in the exact same color, which is fine for a few lines of … Read more

The next challenge for autonomous AI systems is not making them respond faster. It is teaching them how to wait without losing state, holding resources, duplicating work, or breaking the workflow. Most AI agent architectures are designed around a request. A user asks something, the agent thinks, it calls a tool, the tool responds, the … Read more

Preface: Field Data Is the Final Truth In the camera system engineering lifecycle, we have traversed a complete journey. Article 1: Component Selection defined the theoretical system ceiling; Article 2: Lab Build-up & Management established high-precision measurement infrastructure; Article 3: Intrinsic & Extrinsic Calibration built precise geometric awareness for edge AI; Article 4: Factory Testing … Read more

“Let’s split it into agents” has become the AI equivalent of “let’s make it a microservice.” Sometimes the boundary is useful. Sometimes it only creates more state, more coordination, and a harder failure to explain. In production workflows I have built and reviewed, the most dangerous assumption is that separate agents should run in parallel. … Read more

Autonomous technology has covered an enormous amount of ground in the last five years. Tesla, BYD, Waymo, and others have poured billions into self-driving cars, and while the “robotaxi is everywhere” narrative is still ahead of reality, and most deployments in 2025 are geofenced and remotely supervised, the underlying perception-and-control stack has matured a lot. … Read more
