Postfix
What is Postfix? It is Wietse Venema's mail server that started life at IBM research as an alternative to the widely-used Sendmail program. Now at Google, Wietse continues to support Postfix. Postfix runs (or has run) on AIX, BSD, HP-UX, IRIX, LINUX, MacOS X, Solaris, Tru64 UNIX, and other UNIX systems. It requires ANSI C, a POSIX.1 library, and BSD sockets. Postfix attempts to be fast, easy to administer, and secure. The outside has a definite Sendmail-ish flavor, but the inside is completely different. Multiple SMTP deliveries over the same TLS-encrypted connection. This reuses the existing tlsproxy(8) and scache(8) services. MySQL stored procedure support. Gradual degradation: in many cases a Postfix daemon will log a warning and continue providing the services that are still available, instead of immediately terminating with a fatal error. Postfix can set the execute bit on a queue file. If this does not work, then no mail will ever be delivered.

Zypper
Zypper is a command-line package manager for installing, updating, and removing packages. It can also be used to manage repositories. Zypper works and behaves as a regular command-line tool. It features subcommands, arguments, and options that can be used to perform specific tasks. Zypper offers several benefits compared to graphical package managers. Being a command-line tool, Zypper is faster in use and light on resources. Zypper actions can be scripted. Zypper can be used on systems that do not have graphical desktop environments. This makes it suitable for use with servers and remote machines. The simplest way to execute Zypper is to type its name, followed by a command. Additionally, you can choose from one or more global options by typing them immediately before the command. Some commands require one or more arguments. Executing subcommands in the Zypper shell, and using global Zypper options are not supported.

IPFS Cluster
IPFS Cluster provides data orchestration across a swarm of IPFS daemons by allocating, replicating and tracking a global pinset distributed among multiple peers. IPFS has given the users the power of content-addressed storage. The permanent web requires, however, a data redundancy and availability solution that does not compromise on the distributed nature of the IPFS Network. IPFS Cluster is a distributed application that works as a sidecar to IPFS peers, maintaining a global cluster pinset and intelligently allocating its items to the IPFS peers. Cluster peers form a distributed network and maintain a global, replicated and conflict-free list of pins. Ingest IPFS content to multiple daemons directly. Each cluster peer provides an additional IPFS proxy API which performs cluster actions but behaves exactly like the IPFS daemon’s API does. Written in Go, Cluster peers can be programatically launched and controlled.
