Friday Squid Blogging: Squid Populations Are Exploding

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2017/12/friday_squid_bl_607.html

New research:

“Global proliferation of cephalopods”

Summary: Human activities have substantially changed the world’s oceans in recent decades, altering marine food webs, habitats and biogeochemical processes. Cephalopods (squid, cuttlefish and octopuses) have a unique set of biological traits, including rapid growth, short lifespans and strong life-history plasticity, allowing them to adapt quickly to changing environmental conditions. There has been growing speculation that cephalopod populations are proliferating in response to a changing environment, a perception fuelled by increasing trends in cephalopod fisheries catch. To investigate long-term trends in cephalopod abundance, we assembled global time-series of cephalopod catch rates (catch per unit of fishing or sampling effort). We show that cephalopod populations have increased over the last six decades, a result that was remarkably consistent across a highly diverse set of cephalopod taxa. Positive trends were also evident for both fisheries-dependent and fisheries-independent time-series, suggesting that trends are not solely due to factors associated with developing fisheries. Our results suggest that large-scale, directional processes, common to a range of coastal and oceanic environments, are responsible. This study presents the first evidence that cephalopod populations have increased globally, indicating that these ecologically and commercially important invertebrates may have benefited from a changing ocean environment.

Friday Squid Blogging: Gonatus Squid Eating a Dragonfish

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2017/12/friday_squid_bl_606.html

There’s a video:

Last July, Choy was on a ship off the shore of Monterey Bay, looking at the video footage transmitted by an ROV many feet below. A Gonatus squid was spotted sucking off the face of a “really huge dragonfish,” she says. “It took a little while to figure out what’s going on here, who’s eating whom, how is this going to end?” (The squid won.)

Friday Squid Blogging: Squid Product Recall

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2017/11/friday_squid_bl_599.html

Lidl is recalling two of its packaged squid products because of the presence of struvite salt crystals.

The danger is unclear. The article says that struvite crystals “may be mistaken as glass fragments,” which isn’t actually dangerous. It also says: “As these salt crystals may cause injury, the product should not be consumed.” Maybe it’s the intestinal tract that mistakes the crystals for glass.

Now Available – Amazon Linux AMI 2017.09

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/now-available-amazon-linux-ami-2017-09/

I’m happy to announce that the latest version of the Amazon Linux AMI (2017.09) is now available in all AWS Regions for all current-generation EC2 instances. The AMI contains a supported and maintained Linux image that is designed to provide a stable, secure, high performance environment for applications running on EC2.

Easy Upgrade
You can upgrade your existing instances by running two commands and then rebooting:

$ sudo yum clean all
$ sudo yum update

Lots of Goodies
The AMI contains many new features, many of which were added in response to requests from our customers. Here’s a summary:

Kernel 4.9.51 – Based on the 4.9 stable kernel series, this kernel includes the ENA 1.3.0 driver along with support for TCP Bottleneck Bandwidth and RTT (BBR). Read my post, Elastic Network Adapter – High-Performance Network Interface for Amazon EC2 to learn more about ENA. Read the Release Notes to learn how to enable BBR.

Amazon SSM Agent – The Amazon SSM Agent is now installed by default. This means that you can now use EC2 Run Command to configure and run scripts on your instances with no further setup. To learn more, read Executing Commands Using Systems Manager Run Command or Manage Instances at Scale Without SSH Access Using EC2 Run Command.

Python 3.6 – The newest version of Python is now included and can be managed via virtualenv and alternatives. You can install Python 3.6 like this:

$ sudo yum install python36 python36-virtualenv python36-pip

Ruby 2.4 – The latest version of Ruby in the 2.4 series is now available. Install it like this:

$ sudo yum install ruby24

OpenSSL – The AMI now uses OpenSSL 1.0.2k.

HTTP/2 – The HTTP/2 protocol is now supported by the AMI’s httpd24, nginx, and curl packages.

Relational DatabasesPostgres 9.6 and MySQL 5.7 are now available, and can be installed like this:

$ sudo yum install postgresql96
$ sudo yum install mysql57

OpenMPI – The OpenMPI package has been upgraded from 1.6.4 to 2.1.1. OpenMPI compatibility packages are available and can be used to build and run older OpenMPI applications.

And More – Other updated packages include Squid 3.5, Nginx 1.12, Tomcat 8.5, and GCC 6.4.

Launch it Today
You can use this AMI to launch EC2 instances in all AWS Regions today. It is available for EBS-backed and Instance Store-backed instances and supports HVM and PV modes.

Friday Squid Blogging: Squid Empire Is a New Book

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2017/09/friday_squid_bl_594.html

Regularly I receive mail from people wanting to advertise on, write for, or sponsor posts on my blog. My rule is that I say no to everyone. There is no amount of money or free stuff that will get me to write about your security product or service.

With regard to squid, however, I have no such compunctions. Send me any sort of squid anything, and I am happy to write about it. Earlier this week, for example, I received two — not one — copies of the new book Squid Empire: The Rise and Fall of Cephalopods. I haven’t read it yet, but it looks good. It’s the story of prehistoric squid.

Here’s a review by someone who has read it.
