In the time I've been offline, I've been doing a lot and feeling a lot more mentally healthy. I've been exploring nomadnet a bit, looking at reticulum. I'm definitely going to go back to my break and being online much less regularly.
I actually totally forgot about the anniversary of the shooting, which is the first time that's happened since... uh... the shooting, I think.
I've definitely realized that, on some level, I've definitely used Mastodon (and formerly Twitter) as a coping mechanism, often in order to deal with the stressful things that I've found out about on Mastodon or Twitter.
But, again, none of those things really change our core job: build community. And that's part of what I've been neglecting, and what I can focus on more when I'm not spending as much time talking to people all over the world indirectly. Like, I can just chat directly with folks and talk about this shit.
Yeah, I do think there's value in this community. I don't think it's really screaming into the void (at least, not most of the time). But I know that I need the balance to be way farther on the side of direct engagement with comrades doing and building.
So that's what I'm gonna go back to. I feel as though it's a good sign that with all the writing about getting shot that I've been doing, and all the thinking about that, that the actual anniversary of the shooting I'm actually just thinking about bread.
And that seems like a good note to leave on. I'm gonna go back to some hacker shit.

Abstract: The ability to address sub-picosecond events of weak optical signals is essential for progress in quantum science, nonlinear optics, and ultrafast spectroscopy. While up-conversion and optical Kerr gating (OKG) offer femtosecond resolution, they are generally limited to ensemble measurements, making ultrafast detection in nano-optics challenging. OKG, with its broadband response and high throughput without phase-matching, is especially promising when used at high repetition rates under focused illumination.
Here, we demonstrate an ultrafast detection scheme using the third-order nonlinearity of graphene and thin graphite films, operating at 1 GHz with sub-nanojoule pulses and achieving 141 fs temporal resolution. Their exceptionally large nonlinear refractive index, orders of magnitude higher than conventional Kerr media, enhances detection efficiency at smaller thicknesses, enables sub-picosecond response, and supports broadband operation. Their atomic-scale thickness minimizes dispersion and simplifies integration with microscopy platforms, optical fibers, and nanophotonic circuits, making them a compact, practical material platform for nano-optical and on-chip ultrafast Kerr gating.
