by Fred Chong and Kaitlin Smith on Jan 9, 2023 | Quantum Computers (QCs), once thought of as an elusive theoretical concept, are emerging. Today’s quantum devices, however, are still small prototypes since their computing infrastructure is in its early stages. Recent industry roadmaps have started to propose a...

When I worked at Google, fleet-wide profiling revealed that 25-35% of all CPU time was spent just moving bytes around: memcpy, strcmp, copying between user and kernel buffers in network and disk I/O, hidden copy-on-write in soft page faults, checksumming, compressing,...

At 6pm in the evening, you get into a car and tell the restaurant you will have dinner. The car will drive itself there, while you may choose to read a book, surf the web, or take a nap. You may have once considered this a science fiction scene, but now it is becoming...
