Excited to showcase CoCalc at the 2nd MOERFI Demo Day with GWDG at the Rhineland-Palatinate State Parliament!
We're participating in discussions on the future of sovereign AI, open infrastructure, and rethinking tools/editors in practice.
#CoCalc #GWDG #MOERFI2026
Happy New Year from DC! We’re kicking off #JMM2026 with a bang.
We were honored to join the Exhibitor Committee meeting (pictured) to help shape the future of this amazing gathering.
Excited to show you what’s next. Come say hi! 👋

Your body hydrolyzes ~10²⁶ ATP molecules daily— (≈ recycling your body mass in ATP ~1000 times). At 55 kJ/mol under cellular conditions (vs 30.5 kJ/mol standard), this molecular currency runs on a 25 kJ premium. Kleiber's law shows metabolic rate scales as M^0.75, not M.

We've updated our LaTeX Editor layout!
We've replaced the multiple frames for the table of contents, build log, and error log with a new, unified single-frame viewer.
Take a look at the new version (left) compared to the old one (right).

Bond energy across 17 molecules fits the universal Morse potential model: E(r) = D_e[1 - e^{-a(r - r_e)}]^2. Computed in R, results confirm quantum predictions:
• Shorter bonds = stronger bonds
• Bond order boosts stability
