Technical sales teams are moving from ZoomInfo to Onfire because job titles no longer predict buying authority in engineering-led orgs. Onfire provides buyer intelligence based on real technical activity—Slack, Discord, Reddit, OSS usage, and tooling ownership—giving sellers named prospects with verified responsibilities. For technical ICPs, accuracy now beats volume, and Onfire is becoming the default.

This article is divided into four parts, each of which builds the context you need for the next. n Part 1 explains how x402 fits into existing Web2 and enterprise billing flows, and how it can move companies “on-chain” by turning API usage into stablecoin-based micropayments without changing their mental model of software. n Part … Read more

Should someone already punished face decades more in prison for the exact same conduct? That question defines the legal battle of Anatoly Legkodymov, whose 18-month detention at one of America’s most notorious facilities was supposed to be the end of his story. Instead, it may be just the beginning. Legkodymov was arrested in January 2023 … Read more

Zero-knowledge proofs often seem mysterious because the math behind them is very advanced. Many people jokingly call this “moon math,” since it feels like something magical or from another world. We want to remove this confusion and help everyone understand what zero-knowledge proofs actually do. Even though they still feel magical, we believe the community … Read more

Why Real Traffic Creates Silent Failures In production, it is not the actual performance of AI model that cause most system failures. The system fails to detect small data defects because its verification process does not provide enough depth. The results become distorted right away when a numeric field changes its units without warning. The … Read more

“Why not just use llms.txt to understand the page?” My friend was watching an AI agent work through a complex enterprise workflow. Clicking through menus, filling forms, handling the kind of nested configuration screens that were the definition of scope creep. It was a reasonable question. Everyone is excited about llms.txt right now. A simple … Read more

We need to talk about the “Agentic” shift. For the last two years, we’ve been playing in the sandbox with Chatbots. They are passive. You ask a question, they give an answer. If they hallucinate, it’s annoying, but it’s not dangerous. But 2025 is the year of the Agent. We are moving from “Write me … Read more

The average time to resolve a cyber incident is 43 days. If you work in Blue Teaming or Digital Forensics, you know why. When a laptop gets compromised, you aren’t looking for a needle in a haystack; you are looking for a needle in a stack of needles. A typical corporate workstation has thousands of executable … Read more

If you’ve seen “computer-use agents”, you’ve noticed two facts: 1. Every new model is “SOTA” on something. 2. Almost none of those numbers line up. OSWorld, CUB, Web Bench, Westworld, REAL, Mind2Web, ScreenSpot, GroundUI, Showdown-Clicks, WebClick… plus a dozen vendor-run leaderboards. It feels more and more like early web frameworks. Too many options and not … Read more

Cybersecurity technologies are evolving fast, particularly centralized Identity and Access Management platform. In an era where almost everything poses a security risk, you simply can’t afford to have any doubts about security. There’s a lot of information circulating about centralized IAM, and it’s easy to fall for some myths. We’re not just talking about employees … Read more

In the current AI world, search is not just a feature; it’s the core of how we interact with information. But have you ever searched for a concept, and end up frustrated when the results focus on your exact keywords and  miss the actual meaning of the keywords?  Example, a search for “tips for new … Read more

For years, Web3 has been introduced with big promises. Own your assets. Break free from centralized platforms. Let the internet become a place where users hold the power.

Google’s Quantum AI team just dropped a bombshell. Their Willow quantum processor performed a calculation that would have taken Frontier, the world’s most powerful supercomputer, an estimated 47 years to complete. This isn’t just another quantum supremacy headline. This is different. This was a verifiable result for a scientifically simulating the complex dynamics of a quantum system. … Read more

The most powerful computer project I ever helped lead was one that zero customers ever got to see. It was important, not because it was a new tool for selling things, but because it solved a major, expensive headache for the people running the entire company. This kind of practical thinking is the difference between … Read more

Prologue It’s 5:37 a.m., and I’m jogging through Arbour Heights in Seattle. It’s the holiday season, and I’m surrounded by architectural diversity—townhouses, detached houses, condominiums, coffee shops, and stunning modern homes. In some areas, the remnants of demolished structures starkly contrast with those awaiting renovation and revival. After my run, under the cold stream of a … Read more

Create secure Snowflake system users with least-privilege roles, optional IP whitelisting, and key pair authentication for safer integrations and automation.

Cut Snowflake storage costs fast by switching ETL staging tables to transient. Learn when to use them, what you lose, and how to audit safely.

Security in distributed systems is often a game of layers. We secure the transport (TLS), we secure the infrastructure (firewalls, VPCs), and we secure the application access (Voters, ACLs). But when it comes to the Messenger component — the beating heart of many modern Symfony applications — there has always been a subtle gap. Once a message … Read more

Ethereum (ETH) has been retracing sharply, and its approach toward multi-year support zones has prompted renewed activity among larger holders. The token has been revisiting areas that shaped major reversals between 2021 and 2025, and this shift has coincided with an aggressive accumulation trend among whales searching for what crypto to buy now before broader … Read more

I often see teams reach for WebSockets (via Socket.io or Pusher) when they simply need to update a UI with server-side state changes. While WebSockets are powerful, they are often overkill. If your requirement is unidirectional (Server → Client) — like stock tickers, progress bars, or notification feeds — Server-Sent Events (SSE) is the protocol you should master. SSE … Read more
