DRBD
DRBD® (Distributed Replicated Block Device) is an open source, software‑based, shared‑nothing block storage replication solution for Linux, designed primarily to deliver high-performance, high‑availability (HA) data services by mirroring local block devices between nodes in real time, either synchronously or asynchronously. Implemented deep in the Linux kernel as a virtual block‑device driver, DRBD ensures local read performance with efficient write‑through replication to peer(s). User‑space utilities like drbdadm, drbdsetup, and drbdmeta enable declarative configuration, metadata management, and administration across installations. Originally built for two‑node HA clusters, DRBD 9.x extends support to multi‑node replication and integration into software‑defined storage (SDS) systems such as LINSTOR, making it suitable for cloud‑native environments.

CLIAnywhere
CLIAnywhere is a remote terminal application for developers, system administrators, and other users who need a shell on their own Windows, macOS, or Linux computer from an iOS or Android device or a web browser. Its host daemon keeps terminal sessions running on the computer, so users can disconnect and reconnect or switch between desktop and mobile clients without losing the session. An account can link multiple PCs and terminals. CLIAnywhere also provides a file browser with downloads and access to localhost or private LAN web applications on the host. Connections use peer-to-peer networking when possible, with an encrypted relay fallback; no public IP address or port forwarding is required. The host daemon is available under the Business Source License 1.1; personal and internal use is free, while commercial resale or hosting requires a separate license. A free mobile tier is ad-supported; optional Plus ($2.99) and Pro ($9.99) subscriptions are ad-free.

distcc
Distcc is a distributed compilation system that accelerates C, C++, Objective-C, and Fortran builds by offloading compile jobs across multiple networked machines. It integrates seamlessly with GCC and Clang toolchains, transparently intercepting compiler calls and redistributing them to remote daemons while preserving optimization flags, include paths, and dependency tracking. Its client-server architecture features a lightweight listener that manages job queues, prioritizes local compilation when needed, and automatically detects available hosts via simple configuration or DNS. Distcc supports cross-compilation environments, SSH tunneling for secure clusters, blacklisting of unreliable servers, and integration with build systems like Make, CMake and Ninja. Monitoring tools provide real-time statistics on job distribution and throughput, and compatibility with compilation databases (compdb) enables granular control over distributed workloads.
