Your AWS NAT gateway is costing you $1,800+ a month. Here's why and how to fix it.

24+ min ago   (584+ words) This post is the practical fix. We'll cover where the cost actually comes from, three patterns that cut it (VPC endpoints, IPv6 egress, NAT instance), and the platform-level move that handles all three for you. A NAT gateway has two pricing…...

Why Your.NET MCP Tool Classes Crash at Runtime (And the Two-Line Fix)

4+ hour, 27+ min ago   (335+ words) If you're building MCP servers in.NET with instance-based tool classes — the kind that take ILogger, HttpClient, or a repository through constructor injection — there's a good chance you've already hit this at runtime: No warning at startup. No compile-time error....

3 MCP servers I actually use daily (and how to set them up)

5+ hour, 47+ min ago   (140+ words) Not a hype list. These are the three MCP servers I have running right now in Claude Desktop. I use this to let Claude read project files directly instead of me copy-pasting code. Configure it to point at your project…...

The MCP Python SDK 2.0 broke the wrapper libraries. Here's how to spot it and pin back

6+ hour, 34+ min ago   (472+ words) If your MCP tools started failing a few weeks ago and nothing in your own code changed, you're not imagining it. The official Python mcp package shipped 2.0.0 on 2026-07-28. It's a real major version, with public APIs removed and renamed. Latest…...

Prompts Are Code. Genkit Makes the Runtime Reviewable.

7+ hour, 16+ min ago   (764+ words) A prompt can look perfect in a model playground and still fail as a product. The production input arrives in a different shape. Authentication data leaks into the prompt. The model returns prose where the UI expects JSON. A three-line…...
