Siglens is an open-source signal analysis toolkit designed for processing and visualizing time-series data, commonly used in scientific and engineering applications.

witr (short for “Why is this running?”) is a cross-platform command-line utility designed to explain the origin and cause of running processes, services, or anything bound to a port. Traditional tools show what is running, but witr goes a step further by correlating that state across process supervisors, containers, or system services to build a narrative of why the item exists. It supports major operating systems including Linux, macOS, Windows, and FreeBSD, and produces human-readable output that succinctly shows the causal ancestry of a process (e.g., systemd → pm2 → node). witr aims to reduce the time it takes to diagnose processes, especially during debugging or outage investigations, by providing context that would otherwise require manual analysis across multiple tools.

OpenTelemetry-Go is the Go implementation of OpenTelemetry. It provides a set of APIs to directly measure the performance and behavior of your software and send this data to observability platforms. High-quality, ubiquitous, and portable telemetry to enable effective observability. OpenTelemetry is a collection of APIs, SDKs, and tools. Use it to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) to help you analyze your software’s performance and...

...Allows you to store large volumes of high cardinality profiling data cheaply and efficiently. FlameQL enables custom queries to select and aggregate profiles quickly and efficiently for easy analysis. Analyze application performance profiles using our suite of profiling tools. Understand usage of CPU and memory resources at any point in time and identify performance issue before your customer do. Collect, store, and analyze profiles from various external profiling tools in one central location. Link to your Open Telemetry tracing data and get request-specific or span-specific profiles to enhance other observability data like traces and logs.

Grafana OSS is the leading open-source platform for visualization and observability. It enables teams to query, visualize, alert on, and explore telemetry data from multiple sources in a single interface. With support for 100+ data source plugins—including Prometheus, Loki, Elasticsearch, InfluxDB, SQL/NoSQL databases, and OpenTelemetry—Grafana helps teams correlate metrics, logs, and traces across applications and infrastructure. Users can build interactive dashboards with rich...

rat is an experiment in composing shell commands to build interactive, text-based interfaces—think “tig-style” navigation with as little custom UI logic as possible. Rather than reimplementing features, it delegates work to existing tools: a shell command generates output, a pager displays it, and “annotators” attach actions to recognized patterns. For example, a mode might run git log --graph and annotate commit hashes so hitting a key can open a diff, check out a branch, or run a follow-up command. Another mode could list files or search results and let you act on selected lines, chaining shell operations together. ...

Kafka/distributed commit log service in Go. Protocol compatible with Kafka so Kafka clients and services work with Jocko. Use Serf for discovery, Raft for consensus (and remove the need to run ZooKeeper). Able to use percentages of disk space for retention policies rather than only bytes and time kept. Handling size configs when you change the number of partitions or add topics. API versioning [more API versions to implement]. Replication [first draft done - testing heavily now]. Partition...

Testing distributed systems under hard failures like network partitions and instance termination is critical, but it's also important we test them under less catastrophic conditions because this is what they most often experience. Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets. It works by wrapping up some system tools in a portable(ish) way. On BSD-derived systems such as OSX, we use tools like...
