Architecture diagrams have a habit of going stale the moment you redraw them. The boxes stop matching the systems, the arrows stop matching the dependencies, and after a quarter or two the diagram has more in common with the vibe of the system than with the actual one. Dinghy fixes that the same way Terraform fixes ad-hoc infrastructure changes: by treating the diagram as code . The basic shape E…

The article highlights that Microsoft Copilot Cowork is vulnerable to file exfiltration through indirect prompt injection attacks. Attackers can exploit processes that permit agents to operate and access sensitive data via Teams, emails, and shared platforms without immediate user approval. This poses a significant risk when users upload files or interact with compromised content, potentially ena…

In this article, we will look at how the CockroachDB engineering team built this index and the challenges they faced.

Skip to: Results Table | eslint-plugin-security | SonarJS | Microsoft SDL | Interlace | Methodology This is the false-positive deep dive companion to I Benchmarked 17 ESLint Security Plugins . That overview ranks plugins by recall; this one drills into the FP code samples that drive alert fatigue. TL;DR I built a comprehensive benchmark with 40 vulnerable code patterns across 14 security categori…

Journal of Computer Science, Published online: 25 May 2026; doi:10.3844/jcssp.2026.1703.1720 All facets of daily life are now impacted by transaction data. The complex and heterogeneous network created by millions of users, devices, online services, and applications makes digital identity man...

Authorities in the Netherlands have arrested the co-owners of two related Internet hosting companies for operating IT infrastructure used by Russia to carry out cyberattacks, influence operations and disinformation campaigns inside the European Union. The two men were the focus of a 2025 KrebsOnSecurity story about how their hosting companies had assumed control over the technical infrastructure …

Multisig wallets are widely considered one of the most secure methods for managing cryptocurrency assets, especially for teams, DAOs, organizations, and high-net-worth individuals. Unlike traditional single-signature wallets, multisig requires multiple private keys to approve a transaction, significantly reducing the risk of a single point of failure. However, despite their strong theoretical des…

As attackers ramp up their AI exploit development, the search for software vulnerabilities is changing rapidly.

Edge computing is simply localized data processing. But is it still edge computing if it is not connected to the internet? The answer is yes, it is still considered edge computing even when disconnected from the cloud. Edge computing is defined by processing data locally at or near the source—such as on local devices, IoT gateways, or on-premises servers—rather than sending it entirely to a centr…

This is a submission for the Gemma 4 Challenge: Build with Gemma 4 What I Built OpenShift Virtualization Migration Advisor — a local-first assessment tool that ingests legacy hypervisor configurations (VMware .vmx , libvirt domain XML, OVF, RHV/oVirt exports) and produces a structured migration report for moving workloads to Red Hat OpenShift Virtualization . The problem it solves is specific and…

Journal of Mechatronics and Robotics, Published online: 25 May 2026; doi:10.3844/jmrsp.2026.1.8 In an era increasingly defined by digital interconnectivity, the physical security of sensitive hard-copy documents remains a persistent vulnerability in organizational infrastructure. Traditional fil...

Keeping track of a real estate portfolio, be it renting out a single apartment or having dozens of apartment buildings for investment purposes, used to be relegated to often tedious off-line software, like spreadsheet programs, which would struggle to keep up with all the maintenance requests, lease documents, payment records and tenant communications that come in. These days, on the other hand, …

Understand the problem What we're building. A web crawler that runs across independent nodes with no central component. In a distributed crawler, many machines work together, but they still share infrastructure: a common URL queue, a common scheduler, a common database that tracks what has been crawled. In a decentralized crawler, none of that shared infrastructure exists. Each node runs independ…

If you told me a week ago that I could create a custom currency, add brand metadata, enforce automatic transaction fees, and create "soulbound" non-transferable credentials—all without writing a single line of backend API code—I would have been skeptical. Coming from a Web2 background, my brain is wired to think in APIs, Databases, and Middleware. But over the last few days, I’ve been building on…

The Problem We Were Actually Solving Our Treasure Hunt Engine was built on top of a distributed, cloud-native architecture, with event-driven processing at its core. We wanted to deliver an immersive gaming experience where players could participate in location-based challenges, interact with virtual objects, and receive personalized rewards. But as we approached the launch, I realized that our f…

A full technical audit of a coordinated follower inflation network — methodology, findings, and a detection rule simple enough to run in one query. On May 19, 2026, I published "Found a Coordinated GitHub Follow Botnet" — a piece documenting a coordinated follower inflation network on GitHub. The next day, my DEV.to follower count started climbing. Fast. Date New Followers May 19 75 May 20 288 Ma…

Every few years a technology shows up that looks like a product but is actually a protocol. When that happens, the product gets forgotten and the protocol becomes infrastructure. Google I/O 2026 had one of those moments. It just didn't get treated like one. The models were impressive. Gemini 3.5 Flash is four times faster than its predecessors. Antigravity 2.0 makes agent orchestration feel like …

Background : I've spent a decade in cybersecurity and built a security monitoring tool for solo founders and small SaaS teams. I want to talk to more founders in this position - even ones who'll never use my product - so I'm offering 5 free audits this month. What you get: I run a passive security scan…

Operational Technology (OT) is experiencing one of the most remarkable shifts in its history as increased OT and Information Technology (IT) systems converge to form unified, intelligent systems. The aim of this review article is to look at the most important technology trends that are currently changing the OT landscape and consider the impact of these on architecture, operation, and security fo…
