A detailed account of reviving a vintage JavaStation computer, transforming it from a non-functional state to running NetBSD through network booting. The narrative covers troubleshooting steps, configuration details, and successful implementation of RARP, TFTP, and NFS services.
Tailscale creates a virtual private network enabling secure remote access to devices and file sharing without traditional port forwarding. The service offers features like device-to-device connectivity, Taildrop for easy file transfers, and VPN capabilities through Mullvad integration.
An in-depth technical overview of TigerBeetle, a specialized database designed for high-throughput financial transactions with strong consistency guarantees and durability. The system implements a single-threaded, deterministic architecture using static memory allocation and LSM trees, optimized for write-heavy workloads under extreme contention.
A detailed guide explains how to build a TCP/IP stack from scratch, focusing on implementing Ethernet and ARP protocols in userspace Linux. The implementation uses TUN/TAP devices for intercepting network traffic and demonstrates successful ARP request handling, serving as an educational resource for deep network programming.
An in-depth guide demonstrates how to netboot Windows 11 using iSCSI and iPXE, enabling Windows to run from a NAS instead of local storage. The solution allows gaming on Windows while maintaining Linux as the primary OS, providing a practical workaround for AAA games that restrict virtual machine usage.
Fire-Flyer File System (3FS) is a high-performance distributed storage solution optimized for AI workloads, featuring strong consistency and disaggregated architecture. The system achieves impressive throughput of 6.6 TiB/s in read operations across 180 storage nodes, while supporting diverse workloads from data preparation to inference caching.
An analysis of distributed systems programming models reveals limitations in current approaches: external-distribution, static-location, and arbitrary-location paradigms. Despite advancements in distributed systems over the last decade, programming models haven't fundamentally improved, leading to ongoing challenges with concurrency, fault tolerance, and versioning.
An experiment explores the feasibility of creating and transmitting custom network protocols across different operating systems and the internet, revealing significant challenges with OS compatibility and network infrastructure limitations. Results demonstrate that while custom protocols can work locally, they face major obstacles when traversing NAT gateways, firewalls, and cloud providers, ultimately suggesting TCP/UDP remain the most practical choices.
DeepEP is a communication library optimized for Mixture-of-Experts (MoE) and expert parallelism, providing high-throughput GPU kernels and low-latency operations. The library supports both intranode and internode communication, offering specialized kernels for asymmetric-domain bandwidth forwarding and low-latency inference decoding, with comprehensive support for FP8 and RDMA networks.
A detailed walkthrough on building a BitTorrent client in Go, covering core concepts from parsing torrent files to downloading pieces from peers using TCP connections and managing concurrency with channels.
