A number of my free software projects are available on GitHub and mirrored on BitBucket. You might be looking for:
containers — lightweight containers using Linux namespaces
This package is a minimalist implementation of containers for Linux, making secure containers as easy to create and use as a traditional chroot. It comprises three utilities, contain, inject and pseudo, which use the kernel support for user namespaces merged in Linux 3.8.
init — a BSD-style init, daemon, syslog and udev replacement
A lightweight init and syslog suite used in Arachsys Linux, this includes a toolkit of small utilities including a minimal init, a daemon wrapper supporting asynchronous dependencies and logging, a simple but flexible syslog implementation, and an elegant replacement for the increasingly bloated udev daemon.
I sometimes work on an Apple machine running macOS, and it’s convenient to use the built-in IMAP mail client. It isn’t too bad for reading mail, but whilst it once emitted nice RFC2646 format=flowed message bodies, recent releases horribly mangle plain text with a quoted-printable transfer encoding.
MailFlow monkey-patches Apple Mail to emit format=flowed plain text messages, also fixing problems with displaying leading whitespace, and quoting/attribution in replies. MailWrap is an earlier plugin to add a manual line-wrapping and paragraph filling shortcuts in the message composer.
pocketcrypt — a lightweight legacy-free cryptographic library
Pocketcrypt is a tiny legacy-free cryptographic library providing duplex constructions using Gimli or Xoodoo, together with X25519 for key exchange and Schnorr signatures. Eschewing interoperability with the standard museum of primitives and protocols, it offers concise, easily-understood code that avoids the ugly boilerplate and obfuscation of larger libraries.
skd — attach scripts to unix, IPv4 or IPv6 listening sockets
skd is a small daemon which binds to a udp, tcp or unix-domain socket, waits for connections and runs a specified program to handle them. It is ideal as a secure, efficient replacement for traditional inetd as well as being an easy-to-use tool for non-privileged users wanting to run their own network services.
webmidi — a series of self-contained Web MIDI tools
Each single-page application interacts with attached MIDI instruments using the Web MIDI API, runs entirely client-side and depends on no resources outside its static HTML file.
Other bits and pieces including a Bayesian spam filter, paragliding scripts, Yamaha synthesiser stuff, and Arachsys Linux package trees can be found amongst my public GitHub repositories and gists.
Please contact me by email with any comments, bug reports or proposed patches, rather than using GitHub web-based pull requests or issues.
I’m a beef farmer and calf rearer in North Shropshire. I tweet photographs, occasional rants about agricultural technology, and general updates on the cattle and my day-to-day farming exploits as @dairychris on Twitter.
My GnuPG/OpenPGP key is 4096R/2BED3E25 with fingerprint D034 BC11 E7C8 C782 F65C 192D C9BD 2924 2BED 3E25. It is available over Github SSL at https://arachsys.github.io/pgp.txt and on the usual public key servers such as the MIT key server. Please do not use any other keys (revoked or otherwise) to send me encrypted mail.
