First results from the UTMOST-NS pulsar timing programme The UTMOST-NS pulsar timing programme operated at the Molonglo Observatory Synthesis Telescope from April 2021 to June 2023, observing 173 pulsars with an average cadence of 50 pulsars per day. An ove...

On the arXiv today - the final paper of my PhD, discussing results from the slow pulsar timing programme carried out with the North-South arm of UTMOST (may it rest in peace)

OpenAI says it has evidence China’s DeepSeek used its model to train competitor White House AI tsar David Sacks raises possibility of alleged intellectual property theft

OpenAI says it has evidence China’s DeepSeek used its model to train competitor White House AI tsar David Sacks raises possibility of alleged intellectual property theft

OpenAI says it has found evidence that Chinese artificial intelligence start-up DeepSeek used the US company’s proprietary models to train its own open-source competitor, as concerns grow over a potential breach of intellectual property. The San-Francisco-based ChatGPT maker told the Financial Times it had seen some evidence of ‘distillation’, a technique used by developers to obtain better performance on smaller models by using outputs from larger, more capable models. This allows them to achieve similar results on specific tasks at a much lower cost. OpenAI declined to comment further on details of its evidence. Its terms of service state users cannot “copy” any of its services or “use output to develop models that compete with OpenAI”.

I'm so sorry I can't stop laughing. OpenAI, the company built on stealing literally the entire internet, is crying because DeepSeek may have trained on the outputs from ChatGPT. They're crying their eyes out. What a bunch of hypocritical little babies. Cry more, freaks.

I am looking to hire a PhD student at Swinburne University to study the links between pulsars, magnetars and fast radio bursts!

If you or anyone you know may be interested, then please feel free to reach out to me via email.
