Zero to Performance Hero: How to Benchmark and Profile Your eBPF Code in Rust
In this article, we will walk through creating a basic eBPF program in Rust. We will intentionally include a performance regression and then use profilers to locate and fix the bug. We will also create benchmarks and track them using a continuous benchmarking tool for CI.

Comparative Analysis of Major Distributed File System Architectures: GFS vs. Tectonic vs. JuiceFS
As storage needs continue to grow, traditional disk file systems have revealed their limitations. To address the growing storage demands, distributed file systems have emerged as dynamic and scalable solutions. In this article, we explore the design principles, innovations, and challenges addressed by three representative distributed file systems: Google File System (GFS), Tectonic, and JuiceFS.

Debugging Production: eBPF Chaos
This article shares insights into learning eBPF as a new cloud-native technology which aims to improve Observability and Security workflows. You’ll learn how chaos engineering can help, and get an insight into eBPF based observability and security use cases. Breaking them in a professional way also inspires new ideas for chaos engineering itself.

The Service and the Beast: Building a Windows Service that Does Not Fail to Restart
Windows Services play a key role in the Microsoft Windows operating system, and support the creation and management of long-running processes. When “Fast Startup” is enabled and the PC is started after a regular shutdown, though, services may fail to restart. The aim of this article is to create a persistent service that will always run and restart after Windows restarts, or after shutdown.

eBPF and the Service Mesh: Don't Dismiss the Sidecar Yet
While eBPF looks promising to improve service mesh sidecar proxy performance, there are other, simplier ways to improve performance. The layer 7 processing needed for service meshes is unlikely to be feasible in eBPF for the foreseeable future, which means that meshes will still need proxies.

Mobile Video-Conferencing Using Jitsi
In this article, we will look at alternatives for providing video meetings on mobile devices. We take Jitsi as a popular open source option, which provides Jitsi Meet, an ad-hoc video meetings service, and JaaS, a service platform for developers. Looking at user engagement data, we see there’s no "one size fits all" solution.

The Parity Problem: Ensuring Mobile Apps are Secure across Platforms
The problem of security parity is a big one, but it’s part of a larger problem: a general lack of security in mobile apps. By embracing automation for security implementation to the same or greater degree than it has been adopted for feature development, developers can ensure that every app they release for every platform will be protected from hackers, fraudsters, and cybercriminals.

The Compounding (Business) Value of Composable Ecosystems
Being “free” and open source doesn’t hinder the value of these projects to businesses and end users; rather it unlocks it. The composability of open source ecosystems allows the innovation and value of the whole ecosystem to compound on itself.

Netflix Drive: Building a Cloud-Native Filesystem for Media Assets
In this article, Tejas Chopra discusses Netflix Drive, a generic cloud drive for storing and retrieving media assets - a collection of media files and folders in Netflix. Netflix Drive ties together disparate data (such as: AWS S3, Ceph Storage, Google Cloud Storage, and others) and metadata stores in a cogent form for creating, cataloging and serving these assets to applications and workflows.
