About Me

I am Rayan Wu, also known as Peaksol, a software developer and computer science enthusiast. Advocating software freedom and digital rights is one of my main occupations as a free software activist. I also volunteer as a translator for some free software projects.


Feel free to contact me via:

  • E-mail: p@peaksol.org (This is preferred for in-depth discussions. It's strongly recommended that you use plain text emails.);
  • IRC: Peaksol on Libera Chat and LibreIRC (Use this for highly interactive discussions, especially for free software-related topics. As chatting on IRC requires both people to be online at the same time, make sure that you keep your client open in case you miss a message.);
  • Matrix: #peaksol:vern.cc (If you just want to stop by for a chat, I'm also happy to do that on my Matrix channel. Offline messages are supported by Matrix, so you don't have to keep your client open 24/7.).

You may also find me on:

  • Mastodon: @peaksol@floss.social (Please don't DM me on Mastodon; contact me through the ways shown above.);
  • Codeberg: Peaksol;
  • GitHub: @TravinDreek (GitHub is deprecated and I no longer host my new projects there; see Give Up GitHub.).

You won't find me on most popular social media platforms like Twitter or Weibo, nor can you add me on Discord, WeChat, etc. Those platforms require running non-free JavaScripts on your browser or proprietary software on your PC or cellphone. Besides, the centralized design of those platforms leads to privacy issues, censorship, and surveillance.

While it's obvious that distributed systems (Tox, Jami, etc.) are better than federated ones (Matrix, XMPP, etc.) regarding privacy and security, they are yet harder to use than the latter. Thus, I don't currently use a distributed instant messenger most of the time. Hopefully, they'll be easier to use one day.


The key 6D49 A069 F9D6 A94A D521 E9F1 6D8A 1AA4 49E5 51CC has been revoked. You may get a revocation certificate on this site or peaksol.vern.cc.

I don't have an OpenPGP key for now; a new key may be generated sometime soon.

A new Chinese free software community has been established. Check out our website for details and join us now.

Be Free

Tech companies like Microsoft and Tencent takes away your freedom and privacy with their proprietary software that gives them unjust power over the users. Please read their EULAs once more and see what big tech is really doing to you. Kick out those dirty licenses ever more and switch to free software.


Social inertia consists of people who have given in to social inertia. When you surrender to social inertia, you become part of the pressure it exerts on others; when you resist it, you reduce it.
