When someone says AI assisted development, we tend to think of "Vibe Coding", someone hammering in a prompt and getting some code generated or even a full app build with no real idea what bugs there are and sill facing the biggest issue of technical debt in form of missing documentation, speck kit can help you solve this.

Let's continue our journey into prompt injection and see how an agent can be tricked into doing what it's not supposed to do with a simple calendar invite.

Trying to secure an agent by prompt alone will still leave the agent open to attacks you might have not foreseen, let me demonstrate on this simple example.

n8n has released the new guardrails nodes, so I thought it will be a good idea to set up a CTF challenge to see if people would get around the guardrails. Little did I know that both challenges would be completed in under 5 Minutes. This doesn't mean that the guardrails are not useful, read the full story before deciding

You are trying to hold a workshop with 100+ people and solving copy and paste errors with API keys is derailyng your workshop, here's a simple approach on how to simplify this and use some n8n in the process.

Join us for the next n8n Community Meetup in Vienna on September 10th! After our successful June event with 85+ attendees, we're focusing on enterprise n8n features and Microsoft Business integrations. Perfect for professionals looking to scale their automation workflows.

Uptime Kuma is a great open source monitoring tools with great integrations, however I needed a bit more configuration options for notifications

Generating dynamic PDF with Gotenberg, n8n and SeaTable. SeaTable is used as backend for the configuration and gotenberg does the PDF creation while n8n ties it all together.

The n8n Vienna meetup exceeded all expectations with 130 registrations and about 90 attendees. A fantastic evening of automation talks, networking, and community building at Das Packhaus.

With n8n being so easy to use, it is very easy to forget about authentication. What this means is that everyone knowing the URL from the MCP Server would be able to access your data. Ouch.
