Jonathan Frech’s homepage

jblog

logging since 2015, blog.jfrech.com hosts digital projects of mine including but not limited to quines, poetry, simulations, proofs, imagery and thoughts of general nature.

Esoteric Languages

soteric languages explore the space of all pos­si­ble instruction directives without the bur­den­some constraints of usability. Major publicized esolangs of mine include:

krrp

krrp. A functional turing complete esolang focussing on cryptic conciseness whilst preserving capability. It currently has one interpreter, written in pure C. See krrp on GitHub and my krrp an­nounce­ment post. [expand]

Zpr’(h

Zpr’(h. A symbolic, directionally super-lazy esoteric programming language I wrote in the tenth week of the year 2020. See Zpr’(h on GitHub and my Zpr’(h an­nounce­ment post. [expand]

Joy Assembler

Joy Assembler. Frustrated with the lack of an ab­stract yet primitive and hardware-emulating toy assembler, I wrote one myself. You can find its currently only interpreter on GitHub.

Free Software

ree software is much more than only visible: free software at its core values a user’s fundamental rights. It is adherence to this value structure which makes software free.
Yet, most free software can also be viewed. I currently host most of my major public projects on GitHub; whilst I am a fond user of the version con­trol system git, on the political side I have to admit being torn using the eight-legged feline ser­vice overseen by Redmond – its assumed reliability being the major deciding factor.

OEIS

EIS is Neil Sloane’s collection of over 300’000 integer sequences, five of which were contributed by myself; ref. my OEIS Userpage. [expand]

Privacy

rivacy. By requesting my web pages, essential data (currently your request’s time code, its URI, your ip and your user agent) is being logged for a few weeks by my self-written go server. My VPS provider claims to log neither DNS requests nor server requests to any of my sites. If you want to view or delete your log files, please contact me
Naturally, should you choose to use one of my multi-user interactive web pages, actions within them are stored in working memory and parts distributed to all connected clients.
Currently, none of my provided APIs gather data extending the above, though for some services in the future the necessity of gathering might arise.
Other than the above, no data is collected. With overall low ECMAScript usage, banishing any and all third party scripts, I do neither deploy malicious trackers, cookies of any kind nor do I aggregate any data in any form. No data is given to third parties and SSL is strongly encouraged; all certificates are generously provided by Let’s Encrypt.
