+ - Cause of global warming 'hiatus' found deep in the Atlantic-> 2

Submitted by vinces99
vinces99 (2792707) writes "Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth’s surface. More than a dozen theories have now been proposed for the so-called global warming hiatus, ranging from air pollution to volcanoes to sunspots. New research from the University of Washington shows the heat absent from the surface is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. The study is published Aug. 22 in Science.

Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth’s surface. “Every week there’s a new explanation of the hiatus,” said corresponding author Ka-Kit Tung, a UW professor of applied mathematics and adjunct faculty member in atmospheric sciences. “Many of the earlier papers had necessarily focused on symptoms at the surface of the Earth, where we see many different and related phenomena. We looked at observations in the ocean to try to find the underlying cause.”

What they found is that a slow-moving current in the Atlantic, which carries heat between the two poles, sped up earlier this century to draw heat down almost a mile (1,500 meters). Most previous studies focused on shorter-term variability or particles that could block incoming sunlight, but they could not explain the massive amount of heat missing for more than a decade."

The point of Docker and containers in general is that they are running at basically native performance. There is no vm, no virtualized OS, you run under the main OS kernel, but it don't let you see the main OS filesystem, network, processes and so on, and don't let you do operations risky for the stability of the main system. There is some overhead in the filesystem access (in the case of docker, you may be running on AUFS, device mapper, or others that will have different kind of impact in several operations), but still is a far cry from VMs using a filesystem on a file of the main system with its own filesystem driver.

When the only tool you have is a hammer, everything looks like a nail. Now police's only tool are military-grade weapons, intended to kill.

And sometimes the situation changes how people is, like in this Standford prison experiment

Add to that how police cover up miscarriages and that you can't film the police, is not just who watches the watchers, but who watches the watchers that have military-grade weapons in the streets and are abusing of them.

How it affects Blackberry that an Android-based OS focused on security and privacy have some vulnerabilities? Is not BB10 OS based, even having an emulation layer that enables it to run Android programs. They could as well talk about iOS or Windows Phone users too. Even Tizen (that at least run Linux as Android) would be more related to this than Blackberry.

Comment: Containers (Score 1) 98

Run user sessions on linux containers (docker is getting momentum, may be the right option) that you can limit on the resources that they can use, while being far more efficient than VMs for that. Just a word of caution, they aren't as secure as VMs, they may be present or future vulnerabilities that may let hostile students to break their limits and/or access the main system, as they have more surface contact with the machine kernel than proper virtualization, mixing VMs for security with containers for efficiency could be a good compromise.

Testing can show the presense of bugs, but not their absence. -- Dijkstra
