JVM concurrency: Asynchronous event handling in Scala

IBM Developer Works Open Source -

Scala Future and Promise classes give you powerful ways to handle asynchronous processing, including nonblocking ways to organize and sequence events. The async / await constructs, implemented as a macro, make it even easier to write nonblocking event handling in Scala. This tutorial shows you the basic Future and Promise techniques in action, then demonstrates how async / await can convert what looks like simple blocking code to nonblocking execution.

Castro compares NATO to Nazi SS, slams US, Israel for ‘creating ISIS’

‘Stop NATO!’ Anti-militarist protest gains momentum in Wales ahead of summit

Apparently referring to the pressure the North Atlantic Treaty Organization (NATO) has been trying to exert on Moscow in connection with the Ukrainian crisis, which coincides with calls for theramping up of military budgets of NATO member countries, Cuba’s iconic leader accused Western politicians of hypocrisy and aggression.

“Many people are astonished when they hear the statements made by some European spokesmen for NATO when they speak with the style and face of the Nazi SS,” Castro wrote in a column published in Cuban state media.

“Adolf Hitler’s greed-based empire went down in history with no more glory than the encouragement provided to NATO’s aggressive and bourgeois governments, which makes them the laughing stock of Europe and the world.”

Castro, 88, also attacked US Senator John McCain over his policies in the Middle East, describing him as “Israel’s most unconditional ally.”

He accused McCain of supporting Israel’s Mossad intelligence agency as well as participating “together with that service in the creation of the Islamic State, which today controls a considerable and vital portion of Iraq and reportedly one-third of Syria as well.”

Castro attacked the West for its “cynicism” and said that it became “a symbol of imperialist policy.”

“The world has seen no respite in recent years, particularly since the European Economic Community, under the strict and unconditional leadership of the United States, decided the time had come to settle scores with what was left of two great nations (Russia and China) that... had carried out the heroic deed of putting an end to the imperialist colonial order imposed on the world by Europe and the United States,” Castro said.

Instead of promoting conflicts, the governments should “introduce more food, build hospitals and schools for the billions of human beings who desperately need them,” the Cuban leader believes.

Castro stressed that Cuba will continue to resist the US, despite the costs to the Cuban economy due to the US embargo, saying that “there is no worse price than capitulating before an enemy who attacks you without any right to do so.”

‘Cuban people are very well-informed about US attempts to undermine their government’

“When the USSR disintegrated and disappeared from the socialist landscape, we continued resisting and together, the state and the revolutionary people, we’re continuing our independent march,” said Castro.

Castro praised the Soviet Union for “gathering its resources and sharing its technology with a large number of weak and less developed nations, the inevitable victims of colonial exploitation” at the time the union existed.

The leader transferred his presidential powers to his younger brother Raul due to health concerns in 2006, after almost five decades in power.

Since then Castro has written numerous articles and books related to foreign policy.

Hidden Obstacles For Delivery Drones

Slashdot -

An anonymous reader writes: A few days ago we talked over some of the difficulties faced by makers of autonomous car software, like dealing with weather, construction, and parking garages. Today, the NY Times has a similar article about delivery drones, examining the safety and regulatory problems that must be solved in addition to getting the basic technology ready. "[R]researchers at NASA are working on ways to manage that menagerie of low-flying aircraft. At NASA's Moffett Field, about four miles from Google's headquarters in Mountain View, Calif., the agency has been developing a drone traffic management program that would in effect be a separate air traffic control system for things that fly low to the ground — around 400 to 500 feet for most drones. Much like the air traffic control system for conventional aircraft, the program would monitor the skies for weather and traffic. Wind is a particular hazard, because drones weigh so little compared with regular planes." Beyond that, the sheer scale of infrastructure necessary to get drone delivery up and running in cities across the U.S. is staggering. Commercial drones aren't going to have much range, particularly when carrying something heavy. They'll be noisy, and the products they're transporting will still need to be relatively close by. What other issues do Amazon, DHL, Google, and other need to solve?
