@hannah why didn't they add "moon" to the right when there is clearly space for it?

https://youtu.be/gk1X0ATHzMw I have opinions on operating systems 😅
@Waterfox I just downloaded Waterfox and am trying it out because of this statement. Looks good so far :)
@nixCraft Just switched to Waterfox. Might consider Firefox again if this CEO is fired.
@claireon @fedora This is where I am, too - I recommend it if I'm installing it for them and enable+prioritize flathub
A nice thing about releasing simulations as open source is seeing what people do with it; nice work Tim & co! https://opg.optica.org/oe/fulltext.cfm?uri=oe-33-23-47840

Hi ultrafast people! I wrote a FROG reconstruction that will run entirely in your web browser. This I why I like #marimo so much :) The python/rust code for it is all in our attoworld github repository. Right now it only load the .dwc format that we've been using since ancient times, but if you want to use something else just send me an example!
@notjustbikes love and respect to the woman scolding the car stopped next to the tram!
https://www.nature.com/articles/s41566-025-01658-5 Our research on measuring the field of pulses that compress themselves below a femtosecond, just published in Nature Photonics (open access)
Field-resolved attosecond solitons - Nature Photonics

Combining attosecond metrology and soliton dynamics in hollow-core fibres, the generation of attosecond laser pulses from the deep-ultraviolet to the near-infrared regime and the measurement of attosecond solitons with 350-as durations at optical wavelengths are demonstrated, providing an efficient route to generate intense isolated attosecond pulses complementary to those based on high-harmonic generation in gases.
