• Your LLM can scrape the web — locally, without writing throwaway code

  The key line is the nested URL: {{{FromExp=fromJSON(fRes).author_key[0]}}} is an expr-lang expression evaluated against the current item (fRes) — parse it, take the first author key, splice it into the URL. Anything expr-lang can compute can become part of a request: pick a field, concatenate, add an offset, branch on a condition. And notice the output shape: each book keeps its own scalar fields while the... - Source: dev.to / 19 days ago

• I got tired of paying JFrog for a secure OpenTofu / Terraform registry so I built my own

  With OIDC enabled you can leverage fine-grained access control through GroupBinding custom resources. Use the Expr language to bind the groups claim in a user's JWT to specific modules or providers. The moduleResources field also supports glob patterns:. - Source: dev.to / 3 months ago

• Evaluation in Tony Format

  Expressions are evaluated with expr-lang, a Go expression evaluator. Variables come from the threaded environment:. - Source: dev.to / 6 months ago

• Postgres rewritten in Rust, now passing 100% of the Postgres regression tests

  > but it's still a singleton instance, so where do you run it? Most hardware doesn't give you enough uptime for what you need here, because what you actually needed was a re-architecture for distribution / failover / whatever, and while you could ask your LLM to do that you aren't going to run your bank on the result. If only we had a way to solve these issues with tools capable of running Rust programs in that... - Source: Hacker News / about 1 month ago

• Jenkins as a Code, or how I stopped clicking around in the UI

  I run the Jenkins controller in Kubernetes. Helm chart for the deploy, persistent volume for the home dir, a sidecar that injects JCasC config from a ConfigMap. Upgrading Jenkins is just bumping a chart version. Rolling back is rolling back a chart version. Plugin lists are values in a Helm values.yaml file, version-pinned, and reviewed in a pull request like any other change. - Source: dev.to / 3 months ago

• The weekend I fell down the MCP rabbit hole

  Does this scenario sound familiar? It's what happened with containerization before Kubernetes. Kubernetes came along and said: Here's the standard. MCP is doing the same thing for AI tooling. - Source: dev.to / 3 months ago

• Should you build or buy an MCP runtime for enterprise AI agents in 2026?

  Building your own runtime layer is the right call in a narrow set of scenarios. The open-source ecosystem has matured enough that deep platform engineering teams can stand up their own orchestration layer on top of the official Model Context Protocol Python or TypeScript SDKs. The SDKs implement the MCP specification over JSON-RPC 2.0 and support both stdio for local process communication and Streamable HTTP for... - Source: dev.to / 3 months ago

• Deploying a Rust MCP Server to Amazon EKS

  Amazon Elastic Kubernetes Service (EKS) is a fully managed service from Amazon Web Services (AWS) that makes it easy to run Kubernetes on AWS without needing to install, operate, or maintain your own Kubernetes control plane. It automates cluster management, security, and scaling, supporting applications on both Amazon EC2 and AWS Fargate. - Source: dev.to / 3 months ago
