Do you find my software helpful?

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

If you want to feel all warm and fuzzy inside, your financial support is very welcome. Money isn't everything though — if it had been, I wouldn't give away code for free. There are many ways to help the open source and digital rights communities.

Thank you in advance 😃

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

Support 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.

Single Player Tarkov (SPT)
An open source game server reimplementation for the first person shooter (FPS) game (closed-source) Escape from Tarkov (EFT). Players are stuck in post-war Russia, where they have to construct a shelter and gather provisions to survive. Expands EFT's builtin, offline, single-player mode to mimic parts of the highly competitive, online, multiplayer experience. Enables tweaking inventory, player stats, maps, loot, enemies, etcetera. Allows loading modifications, and can emulate some of the live experience such as fluctuating market prices.

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.
Source code, Website, Wikipedia
GNU Affero General Public License (AGPL)
A network-aware variant of the GNU General Public License (GPL). With AGPL, authors allow modification of network-accessible software and services, yet require that they remain free/libre open source to those using them.
Website, Wikipedia
Re-implementation of the game engine in (previously closed-source) Command & Conquer: Red Alert. In a futuristic war between nations and factions of the world, players train and command military units to win over their opponents.
Source code, Website, Wikipedia
Quitessential tool for managing source code for software. Popular with open source projects, and in particular all the projects hosted on (closed-source commercial service) Github.

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.
