We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math. It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training. We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! Blog: https:// rikiyat.github.io/blog/weight-sp ace-programming/ …

Sharing a free AI video leaderboard worth exploring: StreamEval. It covers avatar interaction, world generation, and real-time video editing. The code and evaluation data are public, so you can inspect the scoring and reproduce the tests yourself. It’s a joint initiative by Tsinghua University, NVIDIA, Carnegie Mellon University (CMU), UC Berkeley, Princeton University, the National University of Singapore (NUS), and Reactor. If you’re developing a model, you can also submit your API endpoint for evaluation. https:// streameval.ai #StreamEval #StreamEvalBenchmark #InteractiveVideo #AIRanking

An idea to consider during uncertain geopolitical times: Indian govt gives up to Rs. 78,000 subsidy for solar panels. Some states give additional 20-30k subsidy. So, by investing a little in your own batteries and inverter, and getting the rest, like solar panels, on subsidy, you can get 3 KW of hybrid power (On-grid to avail subsidy, but also can work off-grid during power failure). Typical practical setup: > 2–3 kW solar panels (to claim maximum subsidy) > Hybrid inverter > 3–5+ kWh LiFePO4 battery bank (preferred for longer life) Can keep your home powered for days even if some loserpower adversary takes out the grid, to blame the govt, and causes a blackout. Confirm with your local electricity company whether they allow hybrid configurations in your area (rules can vary by state and I don't know for sure).

Welcome home! After 378 days of isolation while living and working like astronauts on simulated Mars mission, the four-member CHAPEA crew exited the habitat on Oct. 31. Their journey brings NASA a step closer to understanding how crews adapt to long-duration stays. The crew was greeted by family, friends, and the NASA teams behind the mission—and got to bask in the Sun for the first time in over a year! Bravo, CHAPEA!

$ASTS $T : AT&T AND AST SPACEMOBILE: ENGINEERING THE CONNECTED WORLD, ONE HANDOFF AT A TIME New milestone brings seamless connectivity between ground-based and space-based cellular broadband networks, becoming one step closer to commercial service. Key Takeaways: AT&T and AST SpaceMobile, have achieved what we believe is the industry’s first successful handoff between a ground-based cellular network and a direct-to-device satellite network. Supporting ground-based radio, network integration and mobility technologies from Ericsson and Nokia enable the handoff and helps maintain service continuity The achievement advances plans to complement AT&T’s existing wireless network with satellite connectivity in remote and hard-to-reach locations using everyday smartphones. Milestone brings AT&T and AST SpaceMobile one step closer to commercial service keeping customers connected anywhere they work, live, and travel Business Wire DALLAS & MIDLAND, Texas -- November 2, 2026 AT&T and AST SpaceMobile, with supporting ground-based technology from Ericsson and Nokia, have achieved what we believe is the industry’s first successful handoff between a ground-based cellular network and a direct-to-device satellite network. Your phone should just stay connected. Currently, moving between ground and satellite coverage can mean a dropped call or interrupted connection. The companies are engineering a seamless experience where the network does the work behind the scenes, helping you stay connected in more places. The milestone occurred Wednesday, October 21, 2026, outside Granite Falls, Washington, at 8:15 a.m. PT. It builds on previous voice calls, text messages and video calls through AST SpaceMobile’s BlueBird satellites using everyday smartphones. This time, the companies tackled a different challenge: moving a connection between AT&T’s ground-based wireless network and AST SpaceMobile’s satellite network seamlessly. That’s why collaboration matters: AT&T provides America’s strongest nationwide wireless network. AST SpaceMobile provides the satellite network designed to connect directly with everyday smartphones. Ericsson provides AT&T the combined radio and core technology with intelligent network automation to optimize handoffs between ground-based and satellite networks—reducing transition times from seconds to milliseconds, so customers, first responders, and other essential workers stay connected. Nokia provides the radio access technology and mobility software that power AST SpaceMobile’s space-based network enabling seamless handover, service continuity and a smooth customer experience as users move between terrestrial networks and satellite coverage. ”Building on the strength of AT&T’s terrestrial network, AST SpaceMobile satellite connectivity is designed to complement and extend, not replace, the network by extending service to remote and hard-to-reach areas, keeping customers stay connected as wherever they live, work and travel. This successful handoff advances the integration needed to deliver that experience, with terrestrial and satellite networks working together behind the scenes. For customers, the experience should be simple: staying connected without having to think about the technology behind it. Advancing Toward Beta “The successful handoff is a significant milestone, but it’s not the finish line. The next phase is expected to include beta services under real-world conditions, allowing the companies to further refine performance,” says Robert Walters, SVP Network, AT&T. “The broader objective is to progress ultimately to commercial service.” “Together with AT&T we are making cellular broadband coverage from space a seamless part of the mobile network people use every day,” says Wayne Thorsen, Chief Commercial Officer, AST SpaceMobile. “Our space-based network, powered by our BlueBird satellites, with the largest communication arrays ever deployed in low Earth orbit is designed to give people more places to make calls, use their apps, stream content and stay connected with the smartphones they already own. It also adds a new layer of resilience for first responders who depend on reliable communications when it matters most.” As AT&T moves toward beta and commercial service, the focus remains on extending connectivity farther and making it simpler for customers. About AT&T We help more than 100 million U.S. families, friends and neighbors, plus nearly 2.5 million businesses, connect to greater possibility. From the first phone call 140+ years ago to our 5G wireless and multi-gig internet offerings today, we @ATT innovate to improve lives. For more information about AT&T Inc.

I fly a lot and have been tracking this stuff for the past few years using a Radiacode- a pocket-sized spectrometer. I expected much higher radiation rates on regular flights, but the data was actually fairly comforting. What you want is to minimise flying near the poles during space weather events- specifically solar radiation storms, when the Sun throws protons at Earth It is wild to me that people aren't that interested in space weather (or even know how much it affects things!). That airlines don't avoid certain paths during solar radiation storms (S3+) is a shame - exposing crew and passengers to much higher radiation I actively shift travel plans around space weather

Most people will see the $CIFR revenue miss and panic. They shouldn’t. Q3 just printed the first real HPC rent — $5.9M from Black Pearl, and they’re already collecting at Barber Lake too on the first 51 MW (on schedule per the amended timeline). They survived the crypto winter on ~30% BTC mining margins. Now the first HPC leases are running at ~88% gross margin. Tyler was upbeat on the call — financing markets are tighter, but they’re well positioned to deliver. The pure landlord model is awesome and will eventually command a premium for its contracted stability. Barber Lake lease extended to 20 years with a leading AI lab → $9.1B contracted. Pipeline now 5.9 GW, including Colchis 1 GW conditional + up to 2.5 GW on-site gen. Campuses funded through completion. Revenue “miss” is just BTC mining winding down by design — not the AI side. Market is more so pricing in the election catalyst tomorrow than today’s print. Thesis stronger. Still long. Not selling a share.
