Cilium is open-source software for providing, securing and observing network connectivity between container workloads, cloud-native, and fueled by the revolutionary Kernel technology eBPF. Kubernetes doesn't come with an implementation of Load Balancing. This is usually left as an exercise for your cloud provider or in private cloud environments an exercise for your networking team. Cilium can attract this traffic with BGP and accelerate leveraging XDP and eBPF. Together these technologies provide a very robust and secure implementation of Load Balancing. Cilium and eBPF operate at the kernel layer. With this level of context we can make intelligent decisions about how to connect different workloads whether on the same node or between clusters. ...

This is the stress-ng upstream project git repository. stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces. stress-ng was originally intended to make a machine work hard and trip hardware issues such as thermal overruns as well as operating system bugs that only occur when a system is being thrashed hard. Use stress-ng with caution as some of the tests can make a system run hot on poorly designed hardware and also can cause excessive system thrashing which may be difficult to stop.

...A reverse proxy forwards requests between the front-end server and API, while rate limiting and OpenAPI demonstrate additional production-oriented capabilities. Integration tests exercise the REST API, and the backend can also run independently for direct API use. Observability tooling collects logs, metrics, and traces that can be inspected through an integrated dashboard.

Coffee GB is a Gameboy Color emulator written in Java 8. It's meant to be a development exercise. More info can be found in the blog post. First I implemented all the Gameboy CPU opcodes. It’s not exactly the Z80, but it’s pretty close. As a reference, I’ve used the GameBoy CPU Manual - later on I discovered that it has a few typos and is not specific enough for some of the operations. After implementing the opcodes and memory (modelled by an int[] array) I was eager to check whether it’s possible to run some code on it. ...

syzkaller is Google’s coverage-guided, feedback-driven kernel fuzzer designed to uncover reliability and security bugs in operating system kernels at scale. It automatically generates, mutates, and minimizes system call programs, then drives them through a specialized executor (syz-executor) to exercise deep kernel paths. The system integrates tightly with sanitizers such as KASAN, KMSAN, KCSAN, and UBSAN to surface memory safety, concurrency, and undefined behavior issues with actionable reports. A distributed architecture coordinates many fuzzing VMs, collects crash signatures, deduplicates them, and bisects to the first bad commit when possible. syzkaller maintains per-kernel “syz” descriptions so it understands arguments, flags, and resources of thousands of syscalls and ioctls across Linux and other kernels. ...

BadBlood is a PowerShell toolkit that programmatically populates a Microsoft Active Directory domain with a realistic, large-scale structure of OUs, users, groups, computers, and permissions so defenders and testers can practice discovery, hardening, and incident response on a lifelike environment. It intentionally randomizes its output on every run so the created domain, objects, and ACL relationships are different each time, which helps teams exercise tooling and detection logic against varied scenarios. The project is driven by a single entry script (Invoke-BadBlood.ps1) and a collection of modular components that create OUs, seed users and groups, set ACLs, configure LAPS scenarios, and generate other attack/defense artifacts for lab use. Because it modifies a real AD forest, BadBlood requires high privileges (Domain Admin and Schema Admin) to run and the README warns strongly that it is not responsible for cleanup if used in production.

GoBoy is a multi-platform Nintendo GameBoy and GameBoy Color emulator written in go. The emulator can run the majority of GB games and some CGB games. There is also colour and sound support. This emulator was primarily built as a development exercise and is still work in progress. Please feel free to contribute if you’re interested in GameBoy emulator development. The program includes debugging functions making it useful for understanding the emulator operation for building one yourself. These functions include printing of opcodes and register values to the console at each step (although will greatly slow down the emulation) and toggling of individual sound channels. ...

...The moderator alone decides where the players are located along the exercise timeline. Narrator also captures “status reports” from users in the form of timestamped contextual feedback. Narrator is developed by the European Commission's Joint Research Centre (JRC)

The ODS3 Virtual Machine Challenge are downloadable images that can be run as VMWare or VirtualBox instances. The Idea behind the challenge is to test and exercise web application penetration testing in a controlled environment. These images are great for cyber security students, penetration testers and hobbyist. Care should be taken if installed on an Internet access host as the application are purposely vulnerable to attack and exploitation.

Doppioni searches for duplicates in your disks. I wrote Doppioni as exercise, after one year without coding in Java. At the moment is just an alpha version. Help would be very apreciated.... want to join this project?

This is a custom network stack with a process-per-protocol, or more accurately, thread-per-protocol design, supporting a crude distributed database intended as demonstration or exercise for students studying the course of computer networking.

A small, portable shell written in C++. This project is intended as an exercise to improve my programming skills. The goal of this project is to create a DOS-like shell that cross-compiles on Linux and Windows.

Linsanity is a suite of test tools designed to exercise network adapters, opticial storage devices, fixed disks, and audio cards. Each of these tools are "native" plugin applications for the VWM user environement.

Scorebot is a scoring framework which monitors the integrity of various network services for the purpose of scoring a network security exercise.

ISIC is a suite of utilities to exercise the stability of an IP and its component stacks (TCP/UDP/ICMP etc.) It generates piles of pseudo random packets with configurable tendancies, then sent to the target to penetrate its firewall rules or find bug
