Summary The issue at hand is about dependency management in Haskell projects using Stack, where a dependency requires an external library. The dependency’s cabal.project.local file specifies extra-lib-dirs, but this configuration seems to be ignored by Stack when building the dependency. Root Cause The root cause of this issue is that Stack does not automatically use … Read more
Summary In iOS 26, keyboard extensions without full access cannot directly navigate to the host app’s settings page using UIApplication.openSettingsURLString. However, some third-party keyboards (e.g., Baidu, Sogou, WeChat) achieve this functionality despite similar restrictions. This postmortem explores the root cause, real-world impact, and solutions for senior engineers. Root Cause Lack of direct API access: iOS … Read more
Summary The issue arises when comparing the backgroundImage property of document.body.style directly with a string. The property returns a string with quotes around the URL, but the comparison does not account for these quotes, leading to a mismatch. Root Cause Mismatched string formatting: The backgroundImage property includes quotes around the URL, but the comparison string … Read more
Summary A CDK stack attempted to attach a new IAM role to an existing Redshift cluster using Cluster.from_cluster_attributes(). The operation failed because imported Redshift cluster constructs in CDK are read‑only references and do not expose mutating methods such as add_iam_role. Root Cause The failure stems from how AWS CDK models resources: from_cluster_attributes() returns a lightweight … Read more
