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. ...

Go Katas is a curated collection of practice exercises and coding challenges specifically crafted to improve proficiency in Go, including idiomatic patterns, language fundamentals, and algorithm design. It mirrors the kata practice tradition from martial arts—repetitive, thoughtful practice where each exercise reinforces technique, discipline, and problem-solving approach. Each kata prompt focuses on a precise aspect of Go, such as concurrency patterns, memory management, interfaces, error handling, or performance optimization, giving learners structured practice opportunities that go beyond syntax. Implementations can be tested locally, graded automatically with included test suites, and iterated on so that learners get rapid feedback and measurable progress. ...

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. ...

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. ...

Switcher is a proxy server that accepts connections and proxies based on which protocol is detected. Switcher is heavily influenced by sslh. It started out as a learning exercise to discover how sslh worked and attempt an implementation in Go. The result is useful in its own right through use of Go's interfaces for protocol matching (making adding new protocols trivial), and lightweight goroutines (instead of forking, which is more CPU intensive under load).
