How Inventory Buffers in D365 Commerce Help Prevent Multichannel Overselling

·3 views

Overselling — where the same item is sold across multiple channels beyond available stock — is a common and costly problem in multichannel retail, often caused by asynchronous inventory API updates. Microsoft Dynamics 365 Commerce addresses this through inventory buffers and level profiles, which reduce the quantity exposed as available across all channels. For example, setting a 15-unit buffer on 100 physical units means only 85 units are shown as available, blocking bulk orders that would otherwise exceed real stock. The system also categorizes stock into 'in stock', 'low stock', and 'out of stock' thresholds based on the buffer-adjusted figure. This approach is especially critical for marketplace sellers on platforms like Amazon and eBay, where order cancellations from overselling can trigger algorithmic penalties affecting seller rankings.

Waag Moves Bluesky Data to European-Hosted Eurosky Instance

Dutch public technology institute Waag has migrated its Bluesky social media data to Eurosky, a European-hosted alternative instance of the platform. The move reflects growing concerns among European organizations about data sovereignty and reliance on US-based digital infrastructure. Eurosky operates on the AT Protocol, the same open standard underlying Bluesky, allowing interoperability while keeping data within European jurisdiction. Waag published an article explaining its reasoning, citing alignment with its values around open, publicly governed technology. The decision mirrors a broader trend of European institutions seeking greater control over their digital presence and user data.

Oracle PeopleSoft Vulnerabilities Exploited in Attack on Nissan and 100+ Firms

A coordinated cyberattack exploiting vulnerabilities in Oracle PeopleSoft has compromised more than 100 organizations, including Nissan, exposing sensitive employee data. Attackers leveraged known flaws in PeopleSoft's Java deserialization handlers and HTTP endpoints to achieve remote code execution on application servers. Once inside, threat actors were able to harvest authentication tokens, LDAP credentials, password hashes, and OAuth secrets stored within the platform. Because PeopleSoft systems typically integrate with enterprise identity infrastructure such as Active Directory and cloud HR platforms, the breach creates pathways for lateral movement across connected networks. The campaign highlights the elevated risk posed by centralized identity management systems that hold privileged access to broader enterprise environments.

Developer builds AI agent to automate AWS-to-GKE app migration with human oversight

A software developer created an AI-powered tool called a 'skill' for the Antigravity CLI (agy) to automate the refactoring of cloud-dependent codebases from AWS to Google Kubernetes Engine (GKE). The tool addresses common migration pain points such as hardcoded AWS credentials, proprietary SDK usage like boto3, and local disk storage incompatible with ephemeral Kubernetes pods. It works by scanning cloud dependencies, spawning parallel subagents to refactor code and infrastructure, and validating changes on a local Kubernetes cluster before deployment. A mandatory human-in-the-loop (HITL) approval gate is built in to prevent any unsupervised changes from reaching production environments. The approach contrasts with simple scripted find-and-replace methods by using an LLM agent capable of understanding semantic context and adapting to the current state of the codebase.

Go's Built-In pprof Tool Lets Developers Profile Live Services in Minutes

Go includes a built-in profiling tool called pprof that requires no third-party software or agents to operate. Developers can enable it by importing the net/http/pprof package, which registers HTTP endpoints exposing CPU, memory, goroutine, and mutex data. A 30-second CPU sample can be collected using the go tool pprof command, and results can be visualized as flame graphs through a built-in web UI. Flame graphs help identify bottlenecks such as excessive memory allocations, JSON serialization overhead, or lock contention by showing which functions consume the most CPU time. For security, pprof endpoints should only be bound to localhost or a private interface, never exposed on a public port.
