Who would have thought that adding a Sierpinski Triangle Fractal as musical notes would actually sound good!😅

(more on the same theme)
If the ratio of the 2 frequencies is a rational number the orbit on the torus is a closed curve (i.e. the motion is periodic).
If the ratio of the 2 frequencies is irrational the orbit never closes onto itself, and the motion is said to be "quasiperiodic".

“A system can never truly stabilize. This is why utopias are nonsense: even if you design the most perfect society in which everything works brilliantly, it will still have to cope with war and meteors and pandemics and other factors beyond your control. A system can't just work well, it has to fail well.”

This should be enshrined into every design think tank between all the post-its about ‘systemic design.

Do you know that latest version has a built-in HTTP server you can enable to call its API from other applications?

It supports the same API available for plugins and you can use them from whatever language that handles JSON files.

Can't wait to see what integrations with other applications or OS people will come up with. This basically turns your Markdown/Org notes into a local database you can query and write to.

I've never seen anything as brave and open as this in the note taking space:

Thank you @logseq !

We are at most, a few months away from apps with content and sharing mechanisms just not possible on Twitter or other centralized, closed-source platforms. That's when the momentum will really start to build for Activitypub and other protocols supporting federated networks. We have stop talking about it being a twitter "alternative" and start talking about is as an evolutionary step forward in global social networking. Because that's what it is.

#emacs Book mode is an attempt at offering an interface for reading org-mode files with a clean layout. It is based on the use of large margins, headline and mode-line, with leading stars and bullets in the left margin using right alignment and different symbols. All decorations are part of the header-line (including upper left colored part and right upper glyph) and messages are displayed in the mode-line. Code at github.com/rougier/book-mode

We like to think that science and technology are driving increased innovation and change but this research published in @nature indicates that progress and disruption are decreasing. The reasons speculated by Park, Leahey & Funk are interesting. Read more nature.com/articles/s41586-022

Study: Persistent Cardiac Magnetic Resonance Imaging Findings in a Cohort of Adolescents with Post-Coronavirus Disease 2019 mRNA Vaccine Myopericarditis

Abstract:
We describe the evolution of cardiac magnetic resonance imaging findings in 16 patients, aged 12-17 years, with myopericarditis after the second dose of the Pfizer mRNA coronavirus disease 2019 vaccine. Although all patients showed rapid clinical improvement, many had persistent cardiac magnetic resonance imaging findings at 3- to 8-month follow-up.

Study: Persistent varicella zoster virus infection following mRNA COVID-19 vaccination was associated with the presence of encoded spike protein in the lesion

Conclusion:
We presented a case of persistent VZV infection following mRNA COVID-19 vaccination and the presence of spike protein in the affected skin. Further vigilance of the vaccine side effect and investigation for the role of SP is warranted.

Study: Circulating Spike Protein Detected in Post–COVID-19 mRNA Vaccine Myocarditis

Conclusions:
Immunoprofiling of vaccinated adolescents and young adults revealed that the mRNA vaccine–induced immune responses did not differ between individuals who developed myocarditis and individuals who did not. However, free spike antigen was detected in the blood of adolescents and young adults who developed post-mRNA vaccine myocarditis, advancing insight into its potential underlying cause.

Study: Unravelling the role of the mandatory use of face covering masks for the control of SARS-CoV-2 in schools: a quasi-experimental study nested in a population-based cohort in Catalonia (Spain)

Conclusions: We found no significant differences in SARS-CoV-2 transmission due to FCM mandates in Catalonian schools.

**Study: Mask mandate and use efficacy for COVID-19 containment in US States**

Results: Earlier mask mandates were NOT associated with lower total cases or lower maximum growth rates. Earlier mandates were weakly associated with lower minimum COVID-19 growth rates.
