HCP Terraform adds public Terraform module and provider management via organizations
- The Terraform Registry serves as the central discovery and distribution hub for essential public Terraform providers and modules, enabling efficient IaC practices.
- Previously, ownership of public modules and providers was based on an individual's GitHub account, causing management difficulties when the original maintainer left the organization.
- Maintainers can now claim ownership of artifacts within an HCP Terraform organization, reducing maintenance costs and aligning ownership with the organization.
- With the new update, organizations can grant or remove public registry management permissions, connect to GitHub orgs, publish new artifacts, manage GPG keys, and control access to artifacts to ensure only authorized users handle public registry content.

Automatic tag deletion for Docker registries
- Docker registries are crucial for containerized workloads, but storage can be a pain point due to limited capacity or high costs.
- Regmaid is a CLI tool that enforces tag retention policies on Docker registries, independent of the registry implementation and storage backend.
- Regmaid inspects image manifests to determine tag age and deletes tags based on user-defined policies, such as keeping a minimum/maximum number of tags or deleting tags older than a specific time period.
- Regmaid can be installed via Go, configured using a regmaid.yaml file, and automated for convenience using tools like Cron or CronJob on Kubernetes.

Why Outliers Are a Major Headache in Data Analysis
- Outliers, known as non-robust estimators, can significantly impact data analysis by skewing averages and leading to incorrect conclusions.
- Outliers inflate variance and confidence intervals, causing models to perceive data as more variable than it actually is, resulting in flawed forecasts and testing outcomes.
- Outliers can violate model assumptions such as normality and equal variance, leading to biased parameter estimates and misleading feature importance.
- Outliers hide true patterns in data, obscuring trends, seasonality, and periodicity, making it challenging to identify meaningful insights.
