Elad Gil Plots $1.5 Billion Fund, Stretching Definition of a Solo GP
Venture capital firms are under pressure to make rapid-fire decisions about big checks in the frenzied world of artificial intelligence investing, straining partnerships that need a unified front. It helps sometimes to have just one decision-maker.That makes a case for Elad Gil, a prolific ...

Są takie chwile, kiedy siedzisz na WC z pęsetą w dłoni, i nagle zaczyna zastanawiać się, jakie skojarzenia miałby ktoś, kto by to zobaczył.
Także, pęseta dołączyła do mojego standardowego wyposażenia. Wygodniejsza jednak niż paznokcie.

Exploring the Masses of the Two Most Distant Gravitational Lensing Clusters at the Cosmic Noon
Observations over the past decade have shown that galaxy clusters undergo the most transformative changes during the $z = 1.5 - 2$ epoch. However, challenges such as low lensing efficiency, high shape measurement uncertainty, and a scarcity of background galaxies have prevented us from characterizing their masses with weak gravitational lensing (WL) beyond the redshift $z\sim1.75$. In this paper, we report the successful WL detection of JKCS 041 and XLSSC 122 at $z=1.80$ and $z=1.98$, respectiv…

The Scotogenic Model with Two Inert Doublets: Parameters Space and Electroweak Precision Tests
In this work, we study a scotogenic extension of the Standard Model featuring two inert scalar doublets and three singlet Majorana fermions, where neutrino masses are generated radiatively at one loop. The lightest among the Majorana fermions and neutral scalars can serve as dark matter candidates. We explore the parameter space, considering theoretical constraints (perturbativity, unitarity, vacuum stability) and experimental limits (lepton flavor violation, Higgs measurements, electroweak pre…

Robustness of Majorana modes to potential disorder in Fe chains on a superconducting Rashba alloy
Majorana modes offer great potential for fault-tolerant quantum computation due to their topological protection. However, for superconductor-semiconductor nanowire hybrids, intrinsic disorder makes the unambiguous detection of Majorana modes difficult. Here, we construct 1D spin chains from individual Fe atoms on the Rashba surface alloy BiAg2/Ag(111) with proximity-induced superconductivity from a Nb(110) substrate. While the Fe chains exhibit perfect crystalline order, we observe nano-scale p…

Background Measurements and Simulations of the ComPair Balloon Flight
ComPair, a prototype of the All-sky Medium Energy Gamma-ray Observatory (AMEGO), completed a short-duration high-altitude balloon campaign on August 27, 2023 from Fort Sumner, New Mexico, USA. The goal of the balloon flight was the demonstration of ComPair as both a Compton and Pair telescope in flight, rejection of the charged particle background, and measurement of the background $γ$-ray spectrum. This analysis compares measurements from the balloon flight with Monte Carlo simulations to ben…

Show maravilhoso. Pena que é só šudio. O saxofonista é muito bom, suspeito que seja o Mšrio Seve. Bandolinista muito bom também.
Wonderful concert. I wish it had video. Great #sax player. Mšrio Seve, maybe? Great #mandolin too. And Paulinho.

So there's this new "#eDoręczenia" (~ "eDelivery") system that's supposed to replace the previous "ePUAP" system for exchanging signed messages between citizens and offices. I've finally had the opportunity of testing it today, and I have to say, it's magic.
So I wrote the message, attached the ~300 KiB attachment and clicked "Send". Now a status bar appeared on top, saying (in translation):
> Sending message, it can take up to 20 minutes!
Roughly two minutes later the status bar disappeared and I got a blank new message form. So I go into "sent", nothing there. I go into "drafts", there's my message, apparently listed with "delivery data". I click it, click "send" again — the same bar appears, but after a few seconds I'm back to the list. I click "sent", it's finally sent. Magic!

Time for another "review". This one's hard. While the book was quite interesting, it required me to be quite open-minded. Still, I think it's worth mentioning:
Robert Wright — Nonzero: The Logic of Human Destiny
The book basically focused on a thesis that both biological evolution and cultural evolution are a thing, they are directional and this directionality can be explained together using game theory — as eventually leading to more non-zero sum games.
It consists of three chapters. The first one is is focused on the history of civilization. It features many examples from different parts of the world, which makes it quite interesting. The author argues that the culture inevitably is evolving as information processing techniques improve — from writing to the Internet.
The second chapter is focused on biological evolution. Now, the argument is that it's not quite random, but actually directed towards greater complexity — eventually leading to the development of highly intelligent species, and a civilization.
The third chapter is quite speculative and metaphysical, and I'm just going to skip it.
The book is full of optimism. Capitalism creates freedom — because people are more productive when they're working for their own gain, so the free market eliminates slavery. Globalisation creates networks of interdependence that make wars uneconomic. Increased contacts between different cultures makes people more tolerant. And eventually, the humanity may be able to unite facing a common "external" enemy — the climate change.
What can I say? The examples are quite interesting, the whole theory seems self-consistent. Still, I repeatedly looked at the publication date (it's 1999), and wondered if author would write the same thing today (yes, I know I can search for his current opinions).
