Notes from our Physical AI dinner What should a drone do when a police helicopter approaches it? We heard that question at a dinner we recently hosted for engineering leaders and founders working in Physical AI: the AI behind robots, drones, autonomous vehicles, and other machines that sense and act in the real world, along … Read more

Series Context This is the first part of a 5-part series on agentic AI governance. As organizations deploy AI agents that can act across enterprise systems, traditional approaches to governance are proving insufficient. In this part, we examine why AI agents can no longer be treated as invisible automation and why identity and access management … Read more

Data teams spend hours writing SQL queries, pivoting spreadsheets, and waiting for analysts to pull numbers. What if your AI assistant could talk directly to your Snowflake data warehouse — securely, in real time, with full natural language support? That’s exactly what the Model Context Protocol (MCP) enables. In this deep dive, we’ll go far … Read more

Key Takeaways Bitcoin deposits require 2 block confirmations, Ethereum needs 10 confirmations, and USDT on ERC-20 requires 96 network confirmations before crediting. MEXC’s pre-crediting system allows trading after initial confirmations but restricts withdrawals until full blockchain confirmation is complete. Deposits below minimum thresholds will not be credited and cannot be recovered, making it essential to … Read more

When you roll out AI coding assistants to an engineering team, the tooling conversation centers on prompts, models, and context windows. But what gets almost zero attention is whether each repository is configured to give the AI useful context. At Promova, we use Claude Code across our engineering org — everything from mobile apps to … Read more

2:11 AM, Tuesday. Our payment notification service — fires transaction confirmations to roughly 40,000 users — had stopped processing. Completely. No alert fired. Nothing paged the on-call. Slack was dark. The engineer on rotation found out at 2:58 AM because a user tweeted at our support account saying they’d made a payment and hadn’t gotten … Read more

I have spent fifteen years building between Europe, the Gulf, and China. The fastest growing buyers I meet are not reading English in an inbox. They are chatting on WhatsApp in their own language, and most AI tools still cannot meet them there. For years, my work has lived in the space between markets. Launching … Read more

Most SEO tools optimize content creation while leaving outreach fragmented and manual. This article proposes an open-source AI agent that combines keyword research, topic clustering, brief generation, anchor text recommendations, and personalized outreach into a single workflow, reducing manual effort and potentially improving guest-post conversion rates.

Something about the SIM card has bothered me for a long time. We carry phones now that are faster than the computers that put people in space. We’ve been through generation after generation of networks, and yet the little card inside is essentially the same idea it was decades ago. It was built for one … Read more

Hey Hackers! Welcome back to 3 Tech Polls, HackerNoon’s Weekly Newsletter that curates results from our Poll of the Week, and 2 related polls around the web. Thank you for having voted in our polls in the past. This week was a big one. SpaceX, the company that’s spent over two decades being talked about … Read more

A clean address is not a safe protocol. AML tools verify the sender; nothing checks the destination’s structural health. Drift lost $285M through a removed timelock while every wallet read clean. CORE3’s Probability of Loss scores protocol risk 0–100 and serves it to agents over an API, so an agent can refuse a risky destination … Read more

From style references to moodboard UUIDs: a practical developer guide to krea-2-large, Krea’s flagship text-to-image model running on Replicate in 2026.

Clear spec, low consequence: let the agent run. Unclear spec, high consequence: put the tool down. A senior engineer’s honest map of AI’s real limits in production.

The quantum mechanics framework assembled between 1900 and 1927 — from Planck’s energy quantization through Einstein’s photoelectric effect, Bohr’s atomic orbits, de Broglie’s wave-particle duality, and finally Heisenberg and Schrödinger’s mathematical formalization — produced the basis for every piece of hardware running modern cryptography. Transistors. Lasers. Semiconductors. MRI systems. Everything in modern electronics traces back … Read more

Since 2021, Artificial Intelligence (AI) has been readily available for the mass population of people worldwide. Since then, it has pushed forward into a new frontier that could never have been foreseen. The rate of growth that this new technology has seen has never before been experienced in any field. With this development, users have changed how they use AI. While AI is still being used for trivial … Read more

In late 2025, iOS 26 shipped a keyboard that couldn’t keep up with fast typists. Type quickly and characters would go missing. The tap registered, the key animated, but the letter never landed in the field. Worse, the half-finished words poisoned autocorrect, which kept “fixing” text the user never typed. Apple patched it in iOS … Read more

Schema-valid summaries that still fail users The first two articles in this series solved separate problems. The first bound the isolated summary call to a typed NoteSummary. The second kept a refinement flow from drowning in retained transcript. Both are necessary. Neither tells me whether the summary helped the note screen. The uncomfortable case is simple. … Read more

Why founders need governance, security reviews, and human oversight before AI-generated code reaches production The rise of “vibe coding” has changed how software, websites, and marketing systems reach production. Founders can launch projects in hours that once took weeks of development. AI coding assistants can generate landing pages, backend logic, integrations, and content with remarkable … Read more

Bullbit, a decentralized perpetual futures exchange (Perp DEX), has officially launched $BUBI, marking the platform’s Token Generation Event (TGE) and opening a new phase of development. According to Bullbit, $BUBI has a fixed maximum supply of 4 billion tokens, operating on the Base L2 network under the ERC-20 standard in its initial phase. On the … Read more

Most technical founders carry a quiet ranking in their heads. Research sits at the top. Engineering comes next, a notch below, because engineers implement what the researchers discover. Then, somewhere down in the basement, sits sales and marketing: the dirty work, the part you’d skip if you could. The comforting form of this belief is … Read more

I Built a RAG Agent That Was Always Confident and Often Wrong. Here’s What Fixed It. A few months into running one of our newly deployed project – an internal AI agent that let our support team ask plain-English questions about customer accounts instead of digging through four different admin panels, I got a Slack … Read more

Every year, more than $450 billion is bled out of US healthcare administration before a single patient is treated or a single claim is paid. It is not lost to fraud. It is not the product of badly drafted contracts. It evaporates in the space between the moment a patient first picks up the phone … Read more

Is AI a Frankenstein’s monster that threatens to devour its creator by taking away their ability to earn a living? Is it a genie with potentially irreversible destructive tendencies that can never be reined in or stuffed back into the bottle that we released it from? Is it going to mark the end of the … Read more

Dryfus stared through the portal he’d just opened, his heart seized by a sudden rush of fear. He could see a barren, rocky landscape backed by a stormy sky — nothing to hang his hopes on. This was not one of those commercial gateways kept open for long stretches as tourists and travelers stepped between worlds. This … Read more

To rotate proxies without breaking login sessions, keep the same IP address, cookies, browser fingerprint, and user-agent tied together for the duration of a session. Rotate only between sessions, accounts, or workflows. Randomly changing IPs mid-login often triggers security checks, forced logouts, CAPTCHA challenges, or account verification. Login sessions are not just about usernames and … Read more

The CI/CD Pipeline Is Your Compliance Engine. Here’s How to Wire It Up. You’re a few weeks into your SOC 2 process. An auditor you’re paying by the hour, is asking you to manually export six months of access logs, screenshot your deployment approvals, and compile a spreadsheet of every employee who touched production. Meanwhile, … Read more

Most AI memory features work by retrieving past interactions and appending them to a prompt, creating the appearance of personalization without changing how the model actually reasons. This article argues that real personalization requires understanding user motivations, context, and intent rather than simply storing behavioral history. The companies that build systems capable of capturing and … Read more

Imagine this same outage occurring in two different eras: Scenario 1: It’s 2014. Your billing has been returning 500s for almost an hour. The on-call engineer rushes to restart the service and informs everyone on Slack, calmly. Next day, the postmortem doc gets only a couple of comments. Nobody outside the building knows anything has … Read more
