NVIDIA'S NEXT MOVE: POWERING HUMANOID ROBOTS

Nvidia will be leaning more heavily into robotics in 2025. It will launch a new generation of compact computers for humanoid robots called Jetson Thor in the first half of next year. Nvidia aims to provide robot makers with an underlying OEM as its largest customers work to lessen their dependence on the company's AI chips by developing their own.

DEEPSEEK-V3, ULTRA-LARGE OPEN-SOURCE AI, OUTPERFORMS LLAMA AND QWEN ON LAUNCH

Chinese AI startup DeepSeek has released DeepSeek-V3, a 671B parameter model employing a mixture-of-experts architecture, available on Hugging Face. DeepSeek-V3 has outperformed leading models like Meta's Llama 3.1 and rivals closed models such as OpenAI's GPT-4o. The model emphasizes efficient performance with innovations like multi-token prediction, offering substantial training cost savings.

BLUE ORIGIN INCHES CLOSER TO THE FIRST NEW GLENN FLIGHT

Blue Origin successfully performed a hotfire of its New Glenn rocket on December 27, the same day it was issued a commercial space launch license from the US Federal Aviation Administration. The company remains tightlipped about when it will launch its rocket, but it had claimed earlier in the year to be targeting a launch before the end of the year. New Glenn was designed to be partly reusable. Its first stage, which is designed to be good for a minimum of 25 missions, will land on a downrange sea-based platform.

CAUTIOUS OPTIMISM SURROUNDS PLANS FOR THE WORLD'S FIRST NUCLEAR FUSION POWER PLANT

Commonwealth Fusion Systems has announced plans to build the world's first nuclear fusion power plant. The plant will be located in Chesterfield County, Virginia. If successful, the plant will infuse 400 megawatts power into the state's electrical grid starting in the early 2030s. Fusion technology still hasn't been proven to be viable - previous attempts by well-financed tech companies have failed.

WHY CHINA IS BUILDING A THORIUM MOLTEN-SALT REACTOR

China plans to start building a demonstration thorium-based molten-salt reactor in the Gobi Desert next year. The 10-megawatt reactor project is scheduled to be operational by 2030. Thorium-232 is more abundant on Earth than uranium-235, but it isn't directly fissile, so it must first be transformed into fissile uranium-233, which is technically feasible, but it is unknown whether that is economical and practical. If feasible, thorium, which is waste product of China's huge rare earth mining industry, could reduce dependence on uranium.

WHAT IS A DEPENDENCY?

A dependency consists of a checksum, a location, a name, and a version. The checksum is a cryptographic hash of the contents of the dependency. The location tells systems how to acquire the dependency. The name tells when two different dependencies correspond to different versions of the same thing. The version is a specific rule about dependency substitutability.

GENETICALLY EDITED MOSQUITOES HAVEN'T SCALED YET. WHY?

Gene drives are a clever genetic trick that forces a particular gene to be inherited by nearly all offspring rather than the usual 50-50 chance in normal inheritance. They can propagate a desired mutation through an entire population theoretically with only a few mating events. Some iterations of gene drives have been demonstrated to work in fruit flies, but mosquitoes are much more complicated and we don't fully understand them yet. This technology is also being developed in countries where malaria is not endemic - the countries that have problems with mosquitoes may not want to deal with the potential ecological issues that may result from the use of gene drives.

THE WEB IS TOO BIG, OR SCALING DOWN

The modern web is incredibly complex. WebAssembly made web technology the core of the future of computing. We are already using the browser as a replacement for operating systems' graphics toolkits. Simplifying the web won't fix many of the widespread problems. There are a lot of smaller networks currently available that provide a look into what an alternative to the web might look like.
