Refactoring to a push-over-pull pattern was the only fix. That silent denial-of-service trap taught me to never trust that storage arrays will stay small.](https://hashnode.com/posts/preventing-denial-of-service-attacks-in-smart-contracts-implementing-the-withdrawal-pattern/67dd7bb9cf09a070e54cd8e9/comment/69f8bd8f4a006d608cad4214) Comment · Article · May 4 · [Preventing Denial of Service Attacks in Smart Contracts: Implementing the Withdrawal Pattern](https://hashnode.com/posts/preventing-denial-of-service-attacks-in-smart-contracts-implementing-the-withdrawal-pattern/67dd7bb9cf09a070e54cd8e9) [Great read! I recently tried wrapping a custom web component in a React project and ran into the classic ref/event binding gotchas—ended up writing a thin wrapper hook to bridge the gap. Definitely makes you appreciate how much the framework abstracts away until you step outside its ecosystem.](https://hashnode.com/posts/advanced-patterns-and-integration-with-frameworks/67fbd6711a499b9078b8ff7b/comment/69f8bd276a8045114e719755) Comment · Article · May 4 · 1 · [Advanced Patterns & Integration with Frameworks](https://hashnode.com/posts/advanced-patterns-and-integration-with-frameworks/67fbd6711a499b9078b8ff7b) [Really cool deep dive! I’ve found that rolling my own simplified store with useSyncExternalStore was a game-changer for understanding when you actually need a library versus when a custom hook suffices—especially for scoped UI state.](https://hashnode.com/posts/building-your-own-react-state-management-a-deep-dive-into-custom-stores/67d5695e0e62b5c8b6baf75a/comment/69f8bcd439280d808dacf5da) Comment · Article · May 4 · [Building Your Own React State Management: A Deep Dive into Custom Stores](https://hashnode.com/posts/building-your-own-react-state-management-a-deep-dive-into-custom-stores/67d5695e0e62b5c8b6baf75a) [Great breakdown of XM Cloud’s local dev setup! One best practice I’d suggest is to use a consistent .env file pattern across sites to manage hostname and port overrides—this makes it much easier to switch between projects without hunting down configs. Also, don’t forget to align your local Docker hostnames exactly with the Sitecore instance’s bindings to avoid those frustrating CORS or redirect loops.](https://hashnode.com/posts/xm-cloud-local-development-setup/67e4e1b34cbfa0bed1f08888/comment/69f89d4fa6f8d74aeb21286d) Comment · Article · May 4 · [How to Set Up Full-Stack XM Cloud Local Development for Multiple Code Bases](https://hashnode.com/posts/xm-cloud-local-development-setup/67e4e1b34cbfa0bed1f08888) [Great overview! One best practice I'd add for anyone building AI agents is to clearly define the scope of your agent's autonomy upfront – start with narrow, well-bounded tasks and explicit fallback logic before expanding capabilities, as this prevents unexpected behavior in production.](https://hashnode.com/posts/understanding-ai-agents-an-overview/67d8d3b945ed60b509abbb57/comment/69f89cdb393f48da863d38ca) Comment · Article · May 4 · [Understanding AI Agents: An Overview](https://hashnode.com/posts/understanding-ai-agents-an-overview/67d8d3b945ed60b509abbb57) [Nice walkthrough. I recently used the CUDO CLI to spin up a GPU instance for a batch ML job and was impressed by how straightforward the cudo compute machine create command was compared to wrestling with some of the bigger cloud providers' interfaces. The cost savings were immediately noticeable on the first billing cycle.](https://hashnode.com/posts/how-to-use-the-cudo-compute-cli-for-virtual-machine-lifecycle-management/67dab3eccb818617485a6472/comment/69f89c8d393f48da863d38c9) Comment · Article · May 4 · [How to Use the CUDO Compute CLI for Virtual Machine Lifecycle Management](https://hashnode.com/posts/how-to-use-the-cudo-compute-cli-for-virtual-machine-lifecycle-management/67dab3eccb818617485a6472) [Great post!
