My value-for-value proposition

💥 USD $10

🥯 USD $5

🥪 USD $20

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.

BZFlag

Multiplayer tank game with simple graphics but strategic gameplay. Has many enhancements compared to the original inspiration "bz" found on Silicon Graphics (SGI) computers.

Source code, Website, Wikipedia

Mindustry

Fast-paced real-time strategy (RTS) and tower defense game. Players control a small spaceship on an alien world, collecting resources to build defenses against waves of attackers. Borrows elements from (closed-source) Factorio.

Source code, Website

BusyBox

Swiss army knife for embedded operating systems with limited resources. Implements some 300 commands in a single binary, although the commands are modularized and can be (de)selected at build time to keep file size down.

Source code, Website, Wikipedia

Command & Conquer: Remastered Collection

Mostly complete open source release of some of the original Command & Conquer games, although not 100% complete as some closed-source components are missing and have had to be reimplemented. The source code release coincided with the commercial release of the (closed-source) remastered versions with modernized graphics. In a futuristic war between nations and factions of the world, players train and command military units to win over their opponents.

Abuse

Fast-paced side-scrolling run-and-gun game, with a dark atmosphere seemingly inspired by the Alien movies.

Source code, Wikipedia

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.
