I was talking the other day about wavelets and I found this, from @johncarlosbaez 's blog "Azimuth". Here, John and a colleague used the Gabor transform, very related to wavelets, to analyze the Milankovich cyles, an important concept in climate science.
It's really interesting. The Gabor transform, as the wavelets, show information in both frequency and temporal domain, contrary to a Fourier transform that takes you completely to the frequency world or the temporal one.
For a signal whose components may have changed through time, the Gabor can help more than a Fourier analysis. This in fact is what happened with Milankovich, where "recently", in the last million years aprox. the eccentricity seems to be the stronger signal.

Russia is likely acutely aware of these changes and may be trying to see how much they can get away with. And that’s the great irony here: For all the outrage over who *might* be trying to cross the physical border, there’s a striking silence around who has *already* breached our virtual borders.
This is something I hope the fediverse is discussing more deeply. I do think we need some centralized institutions. It's the only way to build trust and safety across a wide audience. I believe those can exist on top of the core decentralized platform without taking away the fundamental freedoms.

#Indiana Lawmakers Trying to Kill Historic Suit Seeking #Gun Industry Accountability
==
One city’s long-running lawsuit against the world’s largest gunmakers is jeopardized by a bill that would allow only the state to sue.
If passed, the law would be retroactive to Aug. 27, 1999 — three days before the lawsuit was filed.
It's my right now feeling VERY FAR AWAY dream that someday software and technology development will be an area mentioned in the same sentence as healthcare, education, and environmental policies when we're talking about "research topics that use causal inference methodologies"
NEW: #Russia has jumped into the #Texas border controversy and is now cheering on civil war in the US and promoting the right-wing border convoy. Even more interestingly, I found evidence that disinformation accounts associated with the notorious Internet Research Agency (Russia’s “troll factory”) may be being “reactivated” to promote a secessionist movement in Texas.

There's a huge disconnect for me rn in the IT space. Companies love to talk about an increasing deficit of smart, talented and skillful people available to help defend the cybers. Welp, a lot of those people are somehow now seeking gainful employment bc they've been laid off. Which is just nuts to me given the sheer scale, resources and effort our adversaries are throwing at everything now.
p.s. AI isn't going to fix anyone's security problems. If anything, it's going to compound them by orders of magnitude (at least in terms of data governance).

They sent it very much on time but I was travelling since early December and could not pick it up!

Theoretical physicist by training (PhD in quantum open systems/quantum information), University lecturer for a bit, and currently paying the bills as an engineer working in optical communication (implementation) and quantum communication (concepts), though still pursuing a little science on the side. I'm interested in physics and math, of course, but I enjoy learning about really any area of science, philosophy, and many other academic areas as well. My biggest other interest is hiking and generally being out in nature.
