Hence a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.” These are all astonishing tools for making our limited capacity for attention more efficient. The market was maturing.

In the next post we’ll look at the detailed analysis of how a team at Etsy handled a particular incident on December 4th 2014, to see what we can learn from it. The organisations that build and operate these systems are themselves often geographically distributed and communicating virtually. Why is this even a thing?

React got popular due to the virtual document object model (DOM) which enables it to enhance performance of web apps and PWA significantly. Usage of Virtual DOM allows efficient rendering where only certain part of webpage is rerendered speeding up performance. It is being actively developed by Facebook and volunteers.

Although a beta version was released in 2014, the first stable release of Kubernetes was just made available in September 2018. The result was Kubernetes, which allows developers to create and manage “clusters” of physical and virtual machines in order to coordinate cooperation via a shared network.

I wrote a page on it: [perf]. - **eBPF**: tracing features completed in 2016, this provides efficient programmatic tracing to existing kernel frameworks. What happens if processes really do try to populate all that virtual memory? It's the official profiler. Or, from a different point of view, Solaris was less secure.)

tl;dr: I don’t want C++ to limit what I can express efficiently. The main improvement MSLs give is that a program data race will not corrupt the language’s own virtual machine (whereas in C++ a data race is currently all-bets-are-off undefined behavior). Efficiency. Then I can still use fully modern C++… just nicer.
