My value-for-value proposition

🌮 USD $20

🌯 USD $5

🐉 USD $10

You can also choose your own donation amount and currency at Paypal. Every once in a while I send thank-you emails to Paypal donors.

Why not simply send a postcard? I rarely receive snail-mail in this digital age, and it would make my day.

Bitcoin (BTC) is magic internet money, and the best option for international donations.

The currency Bitcoin is sometimes abbreviated BTC, XBT, or just ₿.

All Bitcoin donations can be seen in the public (but pseudonymous) blockchain ledger, for example via mempool.space alternatively via mempool⋯.onion.

Direct transfers to my bank account are possible internationally. This is particularly suitable for donations in Swedish Kronor (SEK) or Euro (EUR), since transactions within the European Union (EU) are fast and without fees.

Each and every one can help out in free/libre open source software and digital rights organizations. It doesn't have to take much effort — start your journey based on your own abilities, wants, and needs.

• Help someone install and use open source software.
• Tell a few friends about open source code.
• Share a few links to open source projects and websites.
• Improve project translations in your native tongue.
• Write a bug report.
• Patch a bug and send a pull request.
• Join an open source software workshop or meetup.
• Attend a digital rights workshop or meetup.
• Become a member of a digital rights organization.
• Mention to your boss that many open source developers are happy to write code as contractors.

My own open source software is built with the help of many, many other open source projects — thousands when including subdependencies. Akin to standing on the shoulders of giants, I owe my career to the open source and digital rights communities.

Below are some projects, organizations, and individuals, which I consider worthy of promoting. If you would like to explore something interesting, and perhaps extend your support, these would be some of my recommendations.

tmux

Terminal multiplexer, allowing multiple terminal sessions in a single window. Useful for remote ssh, since tmux allows reconnecting in case of connection problems.

Metal3

Tools for managing Kubernetes clusters built on top of bare-metal infrastructure; Metal-kube. Enables Kubernetes-style cluster management such as provisioning, as used on cloud instances, on physical machines appliances. Reduces reliance on third-party/proprietary cloud computing ("machines owned by others"), in particular for security-focused and high-performance computing.

Source code, Website

pam-u2f

Enables local pluggable authentication module (PAM) authentication using hardware tokens implementing Universal 2nd Factor (U2F) and/or Fast Identity Online 2.0 (FIDO2). Reduces repetitive password typing, in particular when using sudo for system management.

Source code, Website

factorio-docker

Containerized, self-hosted server for the (closed-source) Factorio game. Players construct and automate a factory to build the components required to escape an alien planet.

Source code

GhostText

Turn your code editor to an editor for website inputs in your browser. Enables the conveniences of syntax highlighting, keyboard shortcuts, code formatting, etcetera across the web. Requires both a browser extension and a code editor plugin.

These entries are a randomized subset, refreshed periodically. You may recognize some popular projects already; I have tried to also include lesser-known projects and individual efforts, where some extra exposure and support may make a bigger difference.

See also my list of starred repositories on Github for a much broader, mixed list of both useful and interesting projects.
