How we've redefined the PM and engineer relationship

🔎 Feluda is a Rust-based command-line tool that analyzes the dependencies of a project, notes down their licenses, and flags any permissions that restrict personal or commercial usage.

PGWATCH: PostgreSQL metrics monitor/dashboard

I don't know if you followed the release of the last generation of CPUs. AMD's latest Genoa CPU (AMD EPYC™ 9965) can run 768 threads. It has 192 cores per socket and 2 threads per core, with 2 sockets. Imagine adding 10 TB of RAM to such a beast! Of course, everyone will think of how useful it will be for virtualization. As a database person, I'd rather ask myself what Postgres could do with so many resources. I love simplicity in architecture. But I often meet customers with huge resource needs. With average hosts nowadays, the best answer for them is sometimes multi-parallel processing (MPP).

So, with this new hardware, can we stop using horizontal scalability? To understand the impact of running PostgreSQL on it, we must examine a few technical limits. The analysis will begin with NUMA (Non-Uniform Memory Access) architecture. Next, we will address I/O bandwidth limits. They are a big factor, no matter the CPU or memory. Next, we will look at how PostgreSQL behaves with many connections. This topic has historical limits that bring up key questions. Finally, we will test parallel queries. We will examine their scalability and effectiveness on systems with many CPU threads.

Nping is a Ping tool developed in Rust. It supports concurrent Ping for multiple addresses, visual chart display, real-time data updates, and other features.

JetKVM is a high-performance, open-source KVM over IP (Keyboard, Video, Mouse) solution designed for efficient remote management of computers, servers, and workstations. Whether you're dealing with boot failures, installing a new operating system, adjusting BIOS settings, or simply taking control of a machine from afar, JetKVM provides the tools to get it done effectively.

Tailpipe is the lightweight, developer-friendly way to query logs.

like jq but for Markdown: find specific elements in a md doc

Yaak is a desktop API client for interacting with REST, GraphQL, Server Sent Events (SSE), WebSocket, and gRPC APIs.

Let's discuss logging - unstructured, structured and canonical log lines - what they are and what value they bring to your production systems.

How Redis can be used as a primary database for complex applications that need to store data in multiple formats?

One of the main pieces of advice about Service Level Objectives (SLOs) is that they should focus on the user experience. Invariably, this leads to people further down the stack asking, “But how do I make my work fit the users?”—to which the answer is to redefine what we mean by “user.” In the end, a user is anyone who uses whatever it is you’re measuring.

Terraform HTTP Backend implementation that uses Git repository as storage

TFBuddy allows Terraform Cloud users to get apply-before-merge workflows in their Pull Requests.

Metal3 (pronounced “metal cubed”) is an open-source project that provides a set of tools for managing bare-metal infrastructure using Kubernetes.

Kruize Autotune is an Autonomous Performance Tuning Tool for Kubernetes. Autotune accepts a user provided "slo" goal to optimize application performance. It uses Prometheus to identify "layers" of an application that it is monitoring and matches tunables from those layers to the user provided slo. It then runs experiments with the help of a hyperparameter optimization framework to arrive at the most optimal values for the identified set of tunables to get a better result for the user provided slo.

Autotune can take an arbitrarily large set of tunables and run experiments to continually optimize the user provided slo in incremental steps. For this reason, it does not necessarily have a "best" value for a set of tunables, only a "better" one than what is currently deployed.
