Open an alternate reality. What would DOS be like in 2026 if it was not abandoned by Microsoft?

BritneyDOS is a DOS-style command environment written in Go for 64-bit Linux. The Linux kernel handles modern hardware underneath a familiar command prompt, drive letters, batch files, and a Norton Commander-style file manager.

It includes networking and Wi-Fi, PipeWire audio, a package manager, and tools for building software inside BritneyDOS itself. The native application API and BritneyGUI provide events, timers, windows, controls, file dialogs, and graphics surfaces. Bundled applications include Notepad and Paint.

The Go SDK gives native BritneyDOS applications a documented interface to the system. Its packages cover files, environment variables, processes, memory and network information, installed packages, events, timers, and BritneyGUI.

The SDK is maintained separately from the operating environment and keeps application code behind a stable Go API. It uses no cgo or third-party dependencies.

The best IRC client that Britney has ever used.

AnsiChat is a terminal IRC client written in Go, with keyboard and mouse support, themes, and TOML configuration. It brings a WeeChat-inspired workflow to a client I can shape around the way I use IRC.

Features include an embedded SSH relay for persistent IRC sessions, IRCv3 support, Lua scripting, DCC transfers, and Gotify notifications. Per-buffer drafts, configurable keybindings, custom highlight words, URL collection, an ignore list, and a configurable CTCP VERSION reply support everyday use.

MailSalon is a terminal client for email, contacts, and calendars, written in Go with gotui. It reads local Maildirs and uses configured external commands for receiving and sending mail.

Multiple accounts, compose/reply/forward, attachments, search, OpenPGP integration, contact suggestions, calendar invitations, and calendar views bring the everyday mail workflow into the terminal. Keyboard and mouse controls are supported.

MailSalon and MailSalonGUI now share one codebase, while keeping separate executables and interfaces. The former standalone MailSalon repository points to the consolidated project.

Visit the current shared repository on GitHub or the former MailSalon repository.

MailSalonGUI is the Fyne desktop interface to the same mail, contacts, and calendar core used by MailSalon. It brings a familiar folder list, message list, preview, and compose windows to the desktop.

The GUI supports multiple accounts, formatted mail previews, attachments, bulk message operations, drag-and-drop moves to folders, and remote folder creation and subscriptions through MailSalonSync. It also includes contacts and calendar views.

MailSalonSync is a Maildir-first synchronization tool written in Go. It mirrors configured folders from IMAP or JMAP accounts, supports multiple accounts and folder mappings, propagates deletions, and sends complete email messages through JMAP.

It also discovers and synchronizes CardDAV, CalDAV, JMAP Contacts, and JMAP Calendars collections. Remote folder creation and subscriptions support the MailSalonGUI folder workflow.

An interactive terminal shows the current account, folder, operation, and progress. The -plain option runs synchronously without the interactive display, making it suitable for Emacs, mu4e, scripts, and scheduled jobs.

MailSalonTools converts between EML, Maildir, mbox, and Microsoft Outlook PST. It preserves message content and attachments as faithfully as the destination format allows.

Use command-line options for scripted conversions, or launch it without arguments for a small terminal wizard. It works on its own or alongside MailSalon and MailSalonSync,.

Mbox-to-org turns an email archive into Emacs Org files. It groups messages by sender and day, converts HTML mail to plain text, and extracts attachments into an attachments directory with links from the Org output.

It is useful for bringing archived correspondence into an Emacs-based reading or research workflow.

PurgeHound uses a local Ollama model to classify messages in a Maildir. Messages classified as spam are moved to an Archive-Spam folder for review.

The program relocates messages rather than deleting them. Model selection, worker count, and request timeouts can be configured from the command line.

My maintained fork of outlook-pst-go supplies the PST backend used by MailSalonTools. The upstream project is a pure-Go library for reading and writing Microsoft Outlook PST files.

Work on this fork addresses practical conversion problems involving folders, tables, recipients, attachments, and large messages. It is a contribution to an existing library, with its own upstream authorship.

janeGPT lets you ask local Ollama models questions by email. Jane synchronizes a Maildir, reads incoming requests, gathers configured reference material, and sends threaded replies through your chosen mail command.

Text, Markdown, and Org attachments can provide context. Zeal integration supplies documentation explanations and examples, with complete docset text exports available as Markdown and Org attachments. Additional external tools are configured through TOML.

AnalYzer sends content from URLs and text files to an Ollama model for analysis. Choose a model, supply a custom system prompt, and save the response to a text file.

It can be used for summaries, book reports, or other questions about the supplied material, with support for a custom Ollama server address.

Heartbeat periodically sends system log material to a local Qwen model for a threat-oriented review and writes the model's output to a text file.

The normal workflow runs every ten minutes; a -once mode performs a single scan. It is an experiment in using local language models to help interpret Linux logs.

ircbotz brings a language-model assistant into an IRC channel. Users can ask questions with commands such as !q and !ask, and the bot can send email through a configured msmtp installation.

The bot's nickname and channel are configured in its Go source. This is a separate project from the AnsiChat IRC client.

crush2jxl converts JPEG images to JPEG XL using a pure-Go library. Conversion is pixel-lossless, and no external encoder or cgo is required.

It scans the current directory by default, with optional recursive traversal, parallel workers, live progress, and deletion of originals after successful conversion. Pixel preservation does not include the original JPEG bytes or metadata.
