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…

DuckDB Delta, PostgreSQL 17 Migration, & SQLite Optimization Deep Dives Today's Highlights This week features significant advancements for DuckDB's Delta and Unity Catalog extensions, a critical postmortem on a challenging PostgreSQL 17 migration, and a practical look at SQLite optimization best practices. Delta Grows Up: Writes, Unity Catalog and Time Travel (DuckDB Blog) Source: https://duckdb.…

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

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…

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, …

A single slow query can cascade through your entire application. It holds connections, stalls other transactions, and drives up your cloud bill. When that moment arrives, EXPLAIN ANALYZE is the single most important diagnostic tool you have. What Is EXPLAIN ANALYZE? PostgreSQL ships with two related commands: EXPLAIN displays the query plan the planner intends to use. It shows estimated cost, exp…

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 …

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…

Today's businesses are part of a growing digital ecosystem where they are generating vast amounts of security telemetry data from endpoints, networks, identities, and cloud workloads. Traditional detection models such as Managed Detection and Response (MDR) are unable to correlate signals across these layers, putting organizations at risk of advanced, multi-vector attacks. This paper examines how…

In the last 20 years enterprise network security has been transformed by the rapid growth of cloud computing, increase in remote working patterns, the growing number of connected devices and growing sophistication of cyber adversaries. The traditional perimeter-based security paradigm that's been the working paradigm for protecting organization networks for years is not sufficient anymore in a wo…

6G paradigm enables massive network slicing for pervasive digitization across vertical industries, demanding scalable,sustainable, AI-driven zero-touch automation, particularly under non-IID conditions in live networks. This work introducesa cloud-native service-level agreement (SLA)-driven stochastic policy to guarantee a scalable and fast operation of constrainedfederated learning (FL)-based an…

With the increasing deployment of Reinforcement Learning (RL) for network optimization at the edge of wirelessnetworks, the RL workload emerges as a significant challenge. While the placement of general Machine Learning workloadsacross the cloud–edge continuum has been widely studied, existing solutions typically exclude RL techniques due to theirdistinct structure and operational requirements. I…

Sixth-generation (6G) wireless networks are expected to meet all the demands of the next decade, a feasibility that is onlypossible with advances in network design and management. This paper first proposes a unified resource management framework for a 6G-based network architecture that includes an Open Radio Access Network (O-RAN) deployment and then defines a hierarchical network energy control …

Most students build projects only for grades, portfolios, or tutorials. But what if your project could become: a startup, a real product, a funded idea, or even a global solution? That’s where the Microsoft Imagine Cup stands out. What is Imagine Cup? Imagine Cup is Microsoft’s global student startup and innovation competition where students build real-world tech solutions using modern technologi…

If you're working on Oracle Autonomous Transaction Processing (ATP) , one of the most powerful tools available is SQL Developer Web , also called Database Actions . It allows you to manage your database entirely from the browser no installation required. In this blog, I'll walk you through: Connecting to ATP using Database Actions Creating a table using SQL Developer Web Enabling REST APIs automa…

Almost every new SFMC engagement starts the same way. The client sends a 40-column Excel file of customer data and says "import this into SFMC." The team creates a Data Extension that mirrors the Excel columns. Two weeks later the DE can't send email, can't relate to other DEs, and one field won't import because the data type is wrong. The fix is four decisions made before the DE is created, not …
