Why these Quasar jets appear to travel faster than light

Quasar jets imaged by the Earth Horizon Telescope (EHT) show galactic movements in unprecedented detail. Movements of vast quantities of gas, racing away from Quasar 3C 279 at speeds near the speed of light, reveal signs of a violent past.

In 2019, the The Earth Horizon Telescope (EHT), a network of radio telescopes, released the first-ever image of the region surrounding a black hole. Now, astronomers examining data from this study focused their sights on a different object, a quasar named 3C 279.

Microsoft on Thursday gave the newest Windows 10 upgrade a name, calling it the “May 2020 Update,” signaling that it will launch the refresh next month.

Computerworld had argued that Microsoft would be better served, and better serve customers, if it pushed back the release of Windows 10 2004, the four-digit label it had assigned earlier, by several months. The COVID-19 pandemic and its effect on businesses, notably a massive shift to working at home, the argument went, had so stretched IT resources that adding a Windows upgrade risked breakdowns or even catastrophic failure of core business tools.

Google unveils TensorFlow tool for making mobile-ready models

Google has announced TensorFlow Lite Model Maker, a tool for converting an existing TensorFlow model to the TensorFlow Lite format used to serve predictions on lightweight hardware such as mobile devices.

TensorFlow models can be quite large, and serving predictions remotely from beefy hardware capable of handling them isn’t always possible. Google created the TensorFlow Lite model format to make it more efficient to serve predictions locally, but creating a TensorFlow Lite version of a model previously required some work.

In a blog post, Google described how TensorFlow Lite Model Maker adapts existing TensorFlow models to the Lite
