In this post I'm going to demonstrate 2 reasons I will be avoiding auto-increment fields in Postgres and MySQL in future. I'm going to prefer using UUID fields unless I have a very good reason not to.

Terraform has two looping mechanisms for creating multiple resources, count and for_each. The count meta-argument has been around for a long time, but for_each is a relative newcomer (introduced in version 0.12). Each meta-argument allows you to create more than one resource or module with a single configuration block.

Strategies from SRE leaders fighting noisy alerts in complex system.

s3grep is a parallel CLI tool for searching logs and unstructured content in Amazon S3 buckets. It supports .gz decompression, progress bars, and robust error handling—making it ideal for cloud-native log analysis.

While migrating Pinterest’s search infrastructure — which powers core experiences for millions of users monthly — to Kubernetes, we faced a challenge in the new environment: one in every million search requests took 100x longer than usual.

This post chronicles our investigation, uncovering an elusive interaction between our memory-intensive search system and a seemingly innocent monitoring process. The journey involves profiling search systems, debugging performance issues, Linux kernel features, and memory management.

Multi-protocol service monitoring system with real-time alerts and web dashboard. Supports HTTP/HTTPS, TCP and gRPC monitoring with Telegram notifications.

UiPath Automation Suite has many services that communicate using FQDN (Fully Qualified Domain Name). As this suite operates on the premises of our customers, it provides them with the freedom to select their own FQDN. Often, the certificate required for their chosen FQDN is not signed by a known authority. To talk securely using the HTTPS protocol, all the services must trust the FQDN’s certificate. However, these services are owned by multiple teams. Asking each team to handle this individually is cumbersome and makes managing future certificate trust requests more challenging.

HAMi, formerly known as 'k8s-vGPU-scheduler', is a Heterogeneous device management middleware for Kubernetes. It can manage different types of heterogeneous devices (like GPU, NPU, etc.), share heterogeneous devices among pods, make better scheduling decisions based on topology of devices and scheduling policies.
