Welcome to the third part of my tutorial series about multi-threaded programming in Java 8. This tutorial covers two important parts of the Concurrency API: Atomic Variables and Concurrent Maps.

What's Wrong in Java 8, Part IV: Monads - DZone
Monads are central to Functional programming. They are generally totally ignored in imperative programming. They are even often feared by imperative programmers. Most Java programmers either do not know what a monad is, or would raise strong protest if monads were to be introduced in Java. But, although this has not been much advertised, Java 8 brings monads. In a recent post, (http://java.dzone.c

The company’s winners dream up innovations that they roll out to a quarter-billion customers and accrue small fortunes in soaring stock. Losers leave or are fired in annual cullings of the staff — “purposeful Darwinism,” one former Amazon human resources director said. Some workers who suffered from cancer, miscarriages an
little code, much immutability: java 8 streams and immutable collections – MetaBroadcast
we write about the things we build and the things we consume I finally got to play with Java 8 streams and lambdas in more than a “Hello, World” way a couple of weeks ago. It was all pretty basic stuff—a map here, a few filters there, a sprinkling of counts—but it’s lovely to finally have first-class support for things we’ve been using in Guava for years, and lambdas make the syntax much more ters
Safe Publication and Safe Initialization in Java

If you don’t believe me, go and read "Java Memory Model Pragmatics" transcript again. Most people are trying to digest the JMM rules as stated, and figure out the high-level constructions that are usable without causing developers' heads to explode. Two of the
Cross-origin resource sharing - Wikipedia
Cross-origin resource sharing (CORS) is a mechanism that allows a web page to access restricted resources from a server on a domain different than the domain that served the web page. A web page may freely embed cross-origin images, stylesheets, scripts, iframes, and videos. Certain "cross-domain" requests, notably Ajax requests, are forbidden by default by the same-origin security policy. CORS de
