WebGL 2 launched for other platforms on Chrome and Firefox in 2017. Now in development in WebKit after years of radio silence, WebXR APIs provide Augmented Reality and Virtual Reality input and scene information to web applications. Provides support for "unread counts", e.g. for email and chat programs.

Richard Thaler won the 2017 Nobel prize in Economics for his work on Behavioral Economics. It is much more difficult to publish truly risky, revolutionary research due to implicit filters in what gets funded and what makes it past a program committee. Virtualization, for instance, was being addressed by IBM in the 1960s.

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object).

To efficiently utilize our compute resources, Titus employs a CPU oversubscription feature , meaning the combined virtual CPUs allocated to containers exceed the number of available physical CPUs on a Titus agent. You will notice a do-while loop that is linear to the virtual memory area. Reads a 2GB file into memory. Repeats step 1.
