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.

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.

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.

OpenTTD
Business management simulation game based upon (closed-source) Transport Tycoon Deluxe (TTD). Players run transportation companies hauling passengers and goods.

Perfect Tower 2 AI Scripts
Scripts and utilities for the (closed-source) game Perfect Tower 2, where the in-game "AI" can be scripted to perform routine/repetitive tasks. This set of scripts is a clear time-saver, and are highly optimized to run quickly and efficiently. The player's tower defends against waves of enemies in the testing area, but requires (both idle and incremental) researching and constructing upgrades to not get overrun as difficulty increases.

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.
