Gruber criticizes #Apple’s treatment of Paris Buttfield-Addison after he attempted to redeem a gift card and got his entire Apple account nuked as “Kafkaesque”. But then “Buttfield-Addison posted an update that his account was successfully restored by the ninja on Apple’s Executive Relations team assigned to his case.”
#paper on a paramecium-sized programmable, autonomous robot that integrates sensors. “We operated within a limited power budget of ~100 nW by building our robot in a 55-nm [CMOS] process and leveraging #subthreshold digital logic. (...) In 210 μm by 340 μm by 50 μm, we were able to fit photovoltaic (PV) cells for power, sensors for temperature, four actuator control circuits, an optical receiver for downlink communication and programming, a processor, and memory.” But only barely: “The processor consumed most of the power, requiring nearly a third of the robot’s area to be devoted to energy harvesting to compensate. Even when using larger, low-leakage transistor-based memory, at this process node, we were limited to storing a few hundred bits.” 23 11-bit instructions, and the program could only be 32 instructions long; it had 16 bytes of RAM, 4 8-bit registers, no memory indexing, and no subroutine call and return functionality. #MEMS #robotics #toread

Their recruitment was part of an aggressive drive China launched in 2019 for semiconductor experts working abroad, offering signing bonuses that started at 3 million yuan to 5 million yuan ($420,000 to $700,000) and home-purchase subsidies, according to a review of government policy documents.”
#news on #AI and #export-controls: “#China may have reverse engineered #EUV lithography tool in covert lab, report claims — employees given fake IDs to avoid secret project being detected, prototypes expected in 2028”: “The Chinese machine reportedly generates EUV light with a wavelength of 13.5nm using the same laser-produced plasma (LPP) method as ASML Twinscan NXE machines.”
