Java's new Z Garbage Collector (ZGC) is very exciting
Java 11 features a new Garbage Collector, the Z Garbage Collector (ZGC), which is designed for very low pause times on huge multi-terabyte heaps. In this article we'll cover the motivation for a new GC, a technical overview and some of the really exciting possibilities ZGC opens up.
Hasnain says:
“So how does it perform? Stefan Karlsson and Per Liden gave some preliminary numbers at their Jfokus talk earlier this year. ZGC’s SPECjbb 2015 throughput numbers are roughly comparable with the Parallel GC (which optimises for throughput) but with an average pause time of 1ms and a max of 4ms. This is in contrast to G1 and Parallel who had average pause times in excess of 200ms.”

Two Cops Said They Saw A Man Grope Women. The Women Disagreed. The DA Charged Him Anyway
An 11-month prosecution of a ‘forcible touching’ case sharply diverges from the office’s treatment of Harvey Weinstein, defense attorneys say.
Hasnain says:
“Jocelyn Simonson, an associate professor at Brooklyn Law School, told The Appeal: “The discrepancy between the two cases reveals the presumption of truth-telling given to police officers, where in parallel circumstances a complainant is not necessarily believed; and the presumption of innocence given to more privileged, well-resourced defendants, whereas a less privileged person who is arrested on police officer testimony alone is often presumed guilty.”

Skim reading is the new normal. The effect on society is profound | Maryanne Wolf
When the reading brain skims texts, we don’t have time to grasp complexity, to understand another’s feelings or to perceive beauty. We need a new literacy for the digital age writes Maryanne Wolf, author of Reader, Come Home
Hasnain says:
“The possibility that critical analysis, empathy and other deep reading processes could become the unintended “collateral damage” of our digital culture is not a simple binary issue about print vs digital reading. It is about how we all have begun to read on any medium and how that changes not only what we read, but also the purposes for why we read. Nor is it only about the young. The subtle atrophy of critical analysis and empathy affects us all. It affects our ability to navigate a constant bombardment of information. It incentivizes a retreat to the most familiar silos of unchecked information, which require and receive no analysis, leaving us susceptible to false information and demagoguery.”
