In perhaps the largest single assemblage of America’s tech leaders since they prominently graced the stage at Trump’s inauguration,
Silicon Valley’s powerful decamped to the Saudi capital of Riyadh in May 2025 to join Trump and a coterie of top advisers to solicit investment from the oil-rich kingdom.
Trump didn’t mince words at an afternoon meeting with the Saudi crown prince.
“As you know, we have the biggest business leaders in the world here,”
he said.
“They…

Why these tech titans joined Trump in Saudi Arabia
A cavalcade of tech leaders was on hand in the Saudi capital for an investment summit presided over by President Trump and Saudi Crown Prince Mohammed bin Salman.

Saudi Arabia's millennial crown prince got a rare tour inside Apple's new $5 billion campus
Saudi Crown Prince Mohammed bin Salman has been visiting with Silicon Valley leaders and top tech executives during his US tour.
He met with Apple CEO Tim Cook, Google CEO Sundar Pichai, the Google founders Larry Page and Sergey Brin, Amazon CEO Jeff Bezos, the venture capitalists Marc Andreessen and Peter Thiel, and other key players in the technology industry.
He even got…

Saudi Arabia's millennial crown prince got to see the inside of Apple's new $5 billion campus.

It’s weird that so many people were appalled by Trump’s post of him as Dr. Jesus reviving John McAfee, but I barely heard a peep about the one he posted with him as Jesus on the cross with a crown of thorns.
Tolerance is so fast. I bet he could get away with picturing himself as Mohammed, and I really hope he tries it.

More details about how Trump lost the war with Iran are emerging and also how he couldn't convince Saudi Arabia to let the US use it's airspace.

How the Iran War Ignited a Clash Between Trump and the Saudi Crown Prince
Crown Prince Mohammed bin Salman pressed President Trump earlier to cripple Iran. But as Iran asserted its power, the prince urged a cease-fire, and is now pursuing his security priorities.

Abstract: In this paper, we present a new approach for unmanned aerial vehicle (UAV) positioning and reconfigurable intelligent surface (RIS) partitioning to enhance connectivity of uplink RIS-assisted UAV networks. To achieve this, our approach optimizes RIS-aided link selection, RIS partitioning, and UAV positions to maximize network connectivity characterized by its Fiedler value. Meanwhile, it maintains a specific signal-to-interference plus noise ratio (SINR) constraint for user equipment (UE), which is influenced by RIS partitioning and UAV reliability. The network connectivity optimization problem is formulated using the Fiedler value subject to RIS elements allocation and SINR constraints. This problem is a computationally expensive combinatorial optimization, necessitating an efficient iterative approach. In particular, we propose a perturbation method for RIS-aided link selection, and derive a closed-form solution for RIS partitioning, with each partition tailored to optimize SINR for individual UAV. For the given RIS-aided links and RIS partitioning, we then show that the problem of UAV positioning can be formulated as a low complexity semi-definite programming (SDP) optimization problem, which can be solved using off-the-shelf CVX solvers. Our simulations show the potential gain of UAV positioning and RIS partitioning compared to the benchmark schemes from the literature.

Joint Movable Antenna Positioning and RIS Partitioning for Sum-Rate Maximization

Abstract: This paper investigates the utility of the movable antenna (MA) and reconfigurable intelligent surface (RIS) framework for downlink wireless communications. In the considered scenario, a base station (BS) is equipped with two sub-arrays of MAs transmits signals to the users via the RIS. By jointly exploiting the antenna-positioning flexibility of MAs and the RIS element selection capability, the proposed joint MA-RIS framework introduces additional design degrees of freedom to enhance desired signals and mitigate inter-user interference, thereby maximizing the network sum-rate. To this end, we formulate a joint optimization problem involving MA positioning, sub-array beamforming, and RIS element selection, subject to the minimum antenna separation and transmit power constraints. The resulting problem is highly non-convex and challenging to solve directly. To address this issue, an alternating optimization framework is developed that decomposes the problem into three tractable subproblems. Specifically, zero-forcing beamforming is employed for transmit beamformer design, a low-complexity one-dimensional search is derived for RIS element selection, and the MA positioning problem is solved using block coordinate descent (BCD) and convex optimization techniques implemented via CVX. Simulation results demonstrate that the proposed joint MA-RIS framework significantly improves the achievable sum-rate compared with conventional fixed MAs and benchmark schemes with random configurations.
