Abstract: The discovery of optical frequency combs (OFCs) has revolutionised science and technology by bridging electronics and photonics, driving major advances in precision measurements, atomic clocks, spectroscopy, telecommunications, and astronomy. However, current OFC systems still require further development to enable broader adoption in fields such as communication, aerospace, defence, and healthcare. There is a growing need for compact, portable OFCs that deliver high output power, robust self-referencing, and application-specific spectral coverage. On the conceptual side, progress toward such systems is hindered by an incomplete understanding of the fundamental principles governing OFC generation in emerging devices and materials, as well as evolving insights into the interplay between soliton and mode-locking effects. This roadmap presents the vision of a diverse group of academic and industry researchers and educators from Europe, along with their collaborators, on the current status and future directions of OFC science. It highlights a multidisciplinary approach that integrates novel physics, engineering innovation, and advanced researcher training. Topics include advances in soliton science as it relates to OFCs, the extension of OFC spectra into the visible and mid-infrared ranges, metrology applications and noise performance of integrated OFC sources, new fibre-based OFC modules, OFC lasers and OFC applications in astronomy.

Where should we recommend events & community host long videos that isn't YouTube?
* Vimeo - paid, embeds work, recently acquired is a bad sign
* @… - free, no embeds
* BunnyCDN - paid, lots of options including APIs, no embeds
* Peertube - self-hosted, no embeds

A proud achievement of my half-century IT career happened in 1996 consulting to the #UNDP toward the first published edition of the Humanity Development Library.
It seemed easy enough: "It can be fairly estimated that 1/3, or about 20 million pages of UN, and as much University and NGO material are very useful. Those 20 million pages useful UN publications probably contain about 50% of solutions for major World problems. This information must be released in digital format for non-profit redistribution in all countries."
also portable and accessible to all platforms, everywhere.
Happily, not only did the project live on, but thanks to @… our once-intractable problem of global delivery is now globally solved!
So, whether or not this is timely, I don't know, but should you need to suddenly rebuild some semblance of civilization from scratch…

I'm quite impressed by Fluxpose. It's making me consider selling half of my base stations (not all cause you never know if I will ever need them again) and get a kit once I get my hands on the Steam Frame.
I've rooted for BS tracking for so long because it was the best option out there, but the downsides it brings can be quite annoying sometimes. Plus, the Steam Frame is fully portable and BS tracking is not.
Also I recently learned that Fluxpose was made by an Spanish…
