While MARSOC is testing Ghost Robotics' quadrupedal unmanned ground vehicles (called "Q-UGVs" for short) for various applications, including reconnaissance and surveillance, it's the possibility of arming them with weapons for remote engagement that may draw the most attention.

Those short, easily missable words always mean that there's a lower-end version of the chip coming that doesn't include that many CPU cores, and the tech specs page for the new iPad Pro has the full details: iPad Pros with 256GB or 512GB of storage use a version of the M4 with three high-performance CPU cores and six smaller efficiency cores.

While the FCC voted to restore net neutrality rules on April 25, it didn't release the final text of the order until yesterday. The final text has some changes compared to the draft version released a few weeks before the vote. Both the draft and final rules ban paid prioritization, or fast lanes that application providers have to pay Internet service providers for.
