My value-for-value proposition

🏝 USD $20

🥕 USD $10

🧘‍♂️ USD $5

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.

SCOWL is a database of English words, used to create word lists for spell checkers etcetera.

GNU Privacy Guard (GnuPG, GPG)

GPG is a free and open source implementation of the Open Pretty Good Privacy (OpenPGP) standard for digital data encryption and signing. Has many uses for internet communications, as well as secure file management. Can be used by authors to encrypt private messages directed at specific recipients. Can be used by authors to verifiably sign (public) messages. Can be used for authors to sign, and downloaders to verify the authenticity of, files published on the internet. Can be used to verify the authenticity of stored files and backups. Can be used as a network of trust, where individuals may verify and publish their trust in the digital identity of other network participants.

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.
