Multi-Tenancy Is Not a Deployment Model. It Is a Data Model Decision.

51+ min ago   (940+ words) The meeting lasted eleven minutes. The IT director of a manufacturing group had one question: "We have four subsidiaries. Can they all run on this, with each one only seeing its own data?" Everyone in the room heard a configuration…...

What I learned auditing an open-source AI-memory SDK (and the bug I found in it)

40+ min ago   (511+ words) Most chatbots forget everything the moment a conversation ends. I spent a few days digging into an open-source project (MemWal / Walrus Memory) that tries to fix that — persistent, cross-session memory for AI agents — and ended up doing a full security…...

Building a Type-Safe Database Workflow With Kysely

1+ hour, 17+ min ago   (823+ words) Kysely is a query builder, not an ORM. There's no entity layer, no lazy loading, no magic session flushing things behind your back. You describe your schema once as a TypeScript interface and from there every method on the builder…...

The Hard Part of an API Isn't Calling It

58+ min ago   (480+ words) When I started working with APIs, it was easy to think of them as simple plumbing: Call an endpoint, parse JSON, display the result. That mental model works for a while. Then you build software that depends on real APIs,…...

Impetus Launches Forward Builders Practice

12+ hour, 11+ min ago   (442+ words) Impetus' new enterprise AI practice merges product, design, and engineering into a single role. Its builders arrive knowing which decisions an AI system can safely make on its own, which need a human, and which a regulator will ask to…...

How I built a Stripe billing health audit for SaaS

1+ hour, 38+ min ago   (274+ words) If you run a subscription SaaS on Stripe, a successful checkout does not necessarily mean your billing state will stay healthy forever. Subscriptions can become past_due, payments can remain incomplete, invoices can stay open after collection attempts, and customers can sometimes…...

From APIs to RAG and MCP, how WSO2Con Africa 2026 is connecting AI agents to enterprise systems

19+ hour, 32+ min ago   (899+ words) An enterprise AI agent needs access to more than a large language model. At WSO2Con Africa 2026 in Nairobi, a hands-on session showed how enterprise data and existing systems can be connected to AI agents through tools, APIs, Model Context Protocol (MCP)…...

MCP Went Stateless. Your AI Agent Still Needs State.

2+ hour ago   (1111+ words) One of the more interesting changes in the AI engineering ecosystem in 2026 is happening below the model layer. The latest MCP specification moved the protocol toward a stateless core. That sounds like agents should become stateless too. In fact, as…...

Customer Domain Verification: Scheduled Polling and Triggered Rechecks for Tenant Onboarding

2+ hour, 47+ min ago   (389+ words) Give each fintech tenant a platform-owned subdomain first, and activate it from the platform's own DNS change. For a customer-owned hostname, run scheduled verification in the background and offer a customer-triggered recheck as an extra control. A button alone cannot…...
