Alex, you are always 10 steps ahead of everyone! :P
I have been working on/off on a similar feature for an app (though focusing on sample "management" and finding) that I plan to open-source. :)

1. For that blog - I often share posts with my American leftist friends and I have successfully de-tankified three of them. One went from conspiracies about "Ukrainian nazis" 🤢 to donating to Ukraine and attending local NYC fundraising events (raves :) here is our favorite techno club).

100% agree when it comes to the defaults, I thought it was extremely ugly, unreadable, and non-functional.
However, since I found this customization/setting, I started actually to enjoy it.

and clearly visually demonstrating why pure MSE or MAP are not enough, but also discusses formally why it is at odds with the "perception" or "realism" of the reconstruction and the inherent trade-off. It was an eye-opener for me and changed the way I think about any inverse problems. 3/

My absolutely favorite paper in this space I recommend to anyone working on reconstruction or inverse tasks (or even any machine learning): arxiv.org/abs/1711.06077 "Perception-Distortion Tradeoff". Goes beyond quantifying the error/distortion of the reconstruction statistically, 2/

This was discussed and strongly pushed ~3y before I left Google - in 2019: to rip out most CPU/GPU cores and dedicate chip real estate to ML accelerators.
What Google achieves with them is impressive, but works only for Google ecosystem and lock-in apps. Everything else will suck on those phones.

I would love to see someone with Polish (or Eastern European) nationality/roots, for those our crude, "carved-in-stone" square face and facial features.

I agree 100%. It's one thing to criticize corporate practices, the social impact, ethics, or future risks.
But I watch in total awe how it writes in a few seconds a well documented program in a language/API I don't know, while they complain "but it might have a bug and requires a pass or two" O_o

I get so confused on this. I play around, test, and mess with LLMs all the time and they are miraculous. Just amazing, doing things we dreamed about for decades. I mean, I can ask for obscure things with subtle nuance where I misspell words and mess up my question and it figures it out. It talks to me like a person. It generates really cool images. It helps me write code. And just tons of other stuff that astounds me.
And people just sit around, unimpressed, and complain that ... what ... it isn't a perfect superintelligence that understands everything perfectly? This is the most amazing technology I've experienced as a 50+ year old nerd that has been sitting deep in tech for basically my whole life. This is the stuff of science fiction, and while there totally are limitations, the speed at which it is progressing is insane. And people are like, "Wah, it can't write code like a Senior engineer with 20 years of experience!"

Wow, those are the best-looking HDR photos I have seen (no bs/exaggeration/flattery!). Work well on my iPhone, sadly not on Windows (Edge/Firefox). :(
How did you grade them?
Also, a small website request: footnotes back-references (click to get back) would be super useful, especially on mobile.

As a side note, Ben Gurion was much more radical about it, even with the hindsight knowledge of what happened. Ideological victory and survival of cultures/ideas over the lives of people.
![The Ben-Gurion that emerges from Tom Segev's A State at Any Cost is a singleminded figure obsessively dedicated to the creation of the Jewish State in Palestine. He was not, Segev notes, a man of ideas interested in the development of Zionist theory, but a ruthless political and organization man willing to risk everything to accomplish his state-building goal.
He pursued this even if it meant sacrificing the lives of Jews, let alone those of the Palestinians. Segev cites him telling members of his MAPAI party in the late thirties: "If I knew that it was possible to save all the [Jewish] children in Germany by transporting them to England, but only half by transporting them to Palestine, I would choose the second."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:wm4e6mmexrlsxgzypxk5kbhp/bafkreif6gu7n6l2afcn4xa54vebmegnfc33a63lrnhcntwu2kclzhdj54e@jpeg)

already known that he never demanded a ceasefire or tried to force Bibi to do anything. Even Reagan or Bushes were less pro-Israel. And Trump got a (short...) ceasefire in a week. 2. People "irrationally" care for things like honor or dignity. Initially, all my friends were excited about Kamala. 2/

Who is surprised? I firmly believe Meta is one of the most evil SV companies, led by some of the most spineless people in tech. If they succeed in Metaverse/XR (I doubt, but...) this will get only worse. Why would anyone want to help them build that? (pecunia non olet?💩)

I heard that saying such things about "some" powerful lobbies writing laws is a libel...

Hey @demofox.bsky.social look what I accidentally stumbled upon in Ableton 12 Beta's folders (some new module of Max/MSP, node audio scripting system)! :)

2. Deterministic, square-shaped sharing patterns can introduce correlation, which produces artifacts that are difficult to denoise. We propose a stochastic pattern generation technique that optimizes for randomness, equal lane contributions, and locality. 4/

Standard estimators that combine multiple samples are not only suboptimal, but can increase the error when compared to a single sample! We propose a new, very simple MC estimator that addresses those issues. 3/
