s6-linux-init is a set of minimalistic tools to create a s6-based init system, including an /sbin/init binary, on a Linux kernel.

It is meant to automate creation of scripts revolving around the use of other skarnet.org tools, especially s6, in order to provide a complete booting environment with integrated supervision and logging without having to hand-craft all the details.

s6 is a small suite of programs for UNIX, designed to allow process supervision (a.k.a. service supervision), in the line of daemontools and runit, as well as various operations on processes and daemons. It is meant to be a toolbox for low-level process and service administration, providing different sets of independent tools that can be used within or without the framework, and that can be assembled together to achieve powerful functionality with a very small amount of code.

s6-portable-utils is a set of tiny general Unix utilities, often performing well-known tasks such as cut and grep, but optimized for simplicity and small size. They were designed for embedded systems and other constrained environments, but they work everywhere.

s6-dns is a suite of DNS client programs and libraries for Unix systems, as an alternative to the BIND, djbdns or other DNS clients.

s6-linux-utils is a set of minimalistic Linux-specific system utilities, such as mount, umount, and chroot commands, Linux uevent listeners, a devd device hotplug daemon, and more.

Skribilo is a free document production tool that takes a structured document representation as its input and renders that document in a variety of output formats: HTML and Info for on-line browsing, and Lout and LaTeX for high-quality hard copies.

The input document can use Skribilo's markup language to provide information about the document's structure, which is similar to HTML or LaTeX and does not require expertise. Alternatively, it can use a simpler, “markup-less” format that borrows from Emacs' outline mode and from other conventions used in emails, Usenet and text.

Lastly, Skribilo provides Guile Scheme APIs.

Most is a paging text viewer. It displays the contents of a file or the output of a command on the terminal, one screenful at a time, and lets you scroll up and down to (re)view the entire text.

You can open multiple windows within most to view different files, or to inspect different parts of the same file, at the same time.

S-Lang is a multi-platform programmer's library designed to allow a developer to create robust multi-platform software. It provides facilities required by interactive applications such as display/screen management, keyboard input, keymaps, and so on. The most exciting feature of the library is the slang interpreter that may be easily embedded into a program to make it extensible. While the emphasis has always been on the embedded nature of the interpreter, it may also be used in a stand-alone fashion through the use of slsh, which is part of the S-Lang distribution.

Newt is a windowing toolkit for text mode built from the slang library. It allows color text mode applications to easily use stackable windows, push buttons, check boxes, radio buttons, lists, entry fields, labels, and displayable text. Scrollbars are supported, and forms may be nested to provide extra functionality.

GNU Smalltalk is a free implementation of the Smalltalk language. It implements the ANSI standard for the language and also includes extra classes such as ones for networking and GUI programming.

Pharo aims to provide a clean and innovative Smalltalk-inspired environment. With a stable and small core system, advanced development tools, and maintained releases, the Pharo platform can be used to build and deploy mission critical applications.

Squeak is a full-featured implementation of the Smalltalk programming language and environment based on (and largely compatible with) the original Smalltalk-80 system. Squeak has very powerful 2- and 3-D graphics, sound, video, MIDI, animation and other multimedia capabilities. It also includes a customisable framework for creating dynamic HTTP servers and interactively extensible Web sites.

Poly/ML is a Standard ML implementation. It is fully compatible with the ML97 standard. It includes a thread library, a foreign function interface, and a symbolic debugger.

SML/NJ is an implementation of the Standard ML programming language. Standard ML has many features, including type safety, polymorphism, algebraic data types with pattern matching, higher-order functions, and a sophisticated module system. It is especially well-suited for writing compilers and other language processors.

Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on the Ethereum Virtual Machine.

This package provides shared support code for sr.ht source control services.

This package contains code shared among all sr.ht projects.

Multihash is a protocol for differentiating outputs from various well-established cryptographic hash functions, addressing size + encoding considerations.

This package provides a collection of IPv6 addresses to Autonomous system, a self-hosted API is availalbe from https://github.com/jedisct1/iptoasn-webservice.

Multibase is a protocol for disambiguating the encoding of base-encoded (e.g., base32, base36, base64, base58, etc.) binary appearing in text.

This package provides an ASCII version of Yale Bright Star Catalogue catalog which is a widely used source of basic astronomical and astrophysical data for stars brighter than magnitude 6.5. It provides 9110 stars including B1950 positions, proper motions, magnitudes, and, usually, spectral types.

This package provides specification schemas of InterPlanetary Linked Data which may be used for the test suites of application implementing the standard.

This package provides a set of JSON objects that implementers of JSON Schema validation libraries can use to test their validators.

It is meant to be language agnostic and should require only a JSON parser. The conversion of the JSON objects into tests within a specific language and test framework of choice is left to be done by the validator implementer.

Multicodec is an agreed-upon codec table. It is designed for use in binary representations, such as keys or identifiers (i.e CID).
