Google sends TPUs into space, and AI writes a poem back from orbit.
According to CoinWorld news, Google CEO Pichai announced that the Project Suncatcher prototype satellite launched in early October completed AI inference in space using data-center-grade TPUs for the first time and transmitted the results back to Earth. Engineers sent a prompt from the ground, instructing the TPU on the satellite to run Gemma 4, which wrote a haiku about space. As the satellite passed near Svalbard, Norway, it transmitted back a three-line poem: *Beneath me lies the blue planet, data streams flow silently, starlight nourishes my core.* The satellite carries 4 TPUs, but due to power supply constraints, only 1 of them can currently operate at a time, for about 20 minutes each time. Although space is cold, there is no air to help dissipate heat from the chips, so heat can only be radiated outward through heat pipes and radiators. The impact of cosmic radiation on chip operation also requires further testing. In fact, AI has already been to space long before this. Last December, the U.S. space computing startup Starcloud ran Gemma in orbit using an NVIDIA H100 and even trained a small language model. This time, Google switched to its own TPUs, and the next challenges to solve are the long-term stable operation of the chips and how multiple satellites can collaborate in computing.

Binance's investigation found other vulnerabilities in the system and the compromised computer.
Binance's investigation found additional vulnerabilities in its systems and in the compromised computer, according to CoinWorld news. U.S. crypto exchange Kraken said its team searches for potential vulnerabilities every day, while Coinbase has set the systems storing crypto keys to offline. Several companies told customers that their crypto assets remain safe. OKX founder and CEO Star Xu said the industry needs a real-time alert system so that participants can share information, coordinate responses, and temporarily freeze suspected stolen funds when a participant is hacked. Josh Riezman, Chief Legal and Strategy Director at GSR, believes that apart from Binance, the industry has generally not suffered major losses, but the incident highlights the need to continuously improve security. The attack occurred on the 29th and lasted about 20 minutes. U.S. blockchain analytics firms TRM Labs and Chainalysis both believe the modus operandi is similar to past characteristics attributed to North Korea. Binance's co-CEO said this was a sophisticated attack involving a compromised laptop and malware designed to delete evidence of activity. Binance's investigation also found other points of intrusion in its systems and in the laptop.
Factory acquires Typedef: Before letting a Coding Agent modify data, first figure out what will be affected.
CoinWorld news: Factory has announced the acquisition of data infrastructure startup Typedef and plans to integrate its data context technology into the Coding Agent droid. Typedef can analyze data engineering code such as SQL and map out the dependencies among database fields, data processing workflows, and downstream reports. For example, when a database join field is modified, the program may continue to run as usual, yet it could cause financial reports to double-count revenue. Typedef can help AI detect such cascading effects in advance and trace problems back to their source when data errors occur. In its own data engineering tests, Typedef previously found that after adding this context layer, the Agent's task success rate rose from 46.4% to 81.5%.
