My value-for-value proposition

I offer 70+ software projects, programs, and libraries — free to use for anyone in the world. You can even download all the source code, and modify it to your liking. To develop open source software is not without cost though — it takes technical knowledge, time, and effort.

Is my software useful to you? You can pay what you want, but money isn't everything — there are many ways to support the open source and digital rights communities.

Thank you in advance from the free/libre open source software movement 😃

Support options

Donate using Paypal

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.

Send a postcard

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

Donate Bitcoin

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 alternatively via mempool⋯.onion.

Donate via bank transfer

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.

Help in other ways

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.
Support other projects

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.

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.
Source code, Website
Yubikey touch detector
Linux utility which shows a notification when your Yubikey hardware token is waiting for an in-person touch confirmation. Convenient to have for both local and remote authentication, for example when signing multiple files or connecting through SSH jump hosts.
Source code
Wikimedia Foundation
Provides infrastructure for Wikipedia, Wikibooks, Wiktionary, Wikinews, and the many related projects. The German chapter is a member of the European Digital Rights (EDRi) advocacy group.
Website, Wikipedia
A gnome shell extension for managing clipboard content in Gnome. Conveniently search and reuse recent clipboard history entries.
Source code
Monitor source code during Node.js development, and automatically reload the application upon changes. Speeds up local development by reducing both the number of steps and time required to iterate upon functionality and features.

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.
