They remain one of the key affordable-housing sources nationally, have a limited supply and high tenant retention (10-12Y).
Investors can see tremendous upside with professionally-managed MHP portfolios such as Vintage Capital’s, which targets a 15-17% IRR and makes monthly distributions.
Invest directly in individual deals or via a 10+ property fund. 1031s are also available (NFA).
As Cloudflare's own Customer Zero, their security team manages hundreds of internal production accounts that power critical services. They transformed their manual configuration process into a robust Infrastructure as Code (IaC) system that catches issues before deployment and ensures consistent security across their global edge network.
The challenge: Building a scalable system to manage hundreds of Cloudflare accounts while preventing misconfigurations that could instantly propagate across their global network.
Implementation highlights:
Centralized monorepo: All configurations live in one repository with clear team ownership
Custom CI/CD pipeline: Built on Atlantis and GitLab with a secure state management system
Policy as Code: 50+ security policies written in Rego and enforced via Open Policy Agent
Automated drift detection: Custom service that monitors and alerts on configuration changes
Exception management: Formal process for handling policy exceptions through code
Results and learnings:
Improved security: Caught configuration errors before deployment through automated policy checks
Better scalability: Changes can be rapidly deployed across hundreds of accounts
Increased velocity: Teams move faster with confidence that changes are compliant
Moving from click-ops to Infrastructure as Code isn't just about automation - it's about building confidence in your changes. Cloudflare's approach shows that treating configuration like code leads to better security and faster deployments.

This week’s coding challenge:
This week’s tip:
Configure OpenTelemetry tail-based sampling to reduce trace volume while preserving error traces and long-duration spans. This approach samples after span completion, enabling intelligent decisions.
Wen?
High-throughput microservices: 100k+ spans/second overwhelming trace backends
Cost optimization: Reducing trace storage costs while maintaining error visibility
Compliance requirements: Ensuring all failed operations are traced for audit purposes
Luck is a matter of preparation meeting opportunity.
