The perils of using voice commands with IoT machines

Earlier this week, German carmaker Volkswagen announced an upgrade to its VW Car-Net mobile app that lets iPhone users control their Golfs and Jettas using Siri commands. Specifically, iPhone users on iOS 12 can say, “Hey, Siri” to lock and unlock the car, check estimated range remain, flash the warning lights, and toot the horn. You can also add Shortcuts to Siri with personalized phrases to start/stop charging, defrosting, and climate controls; set the temperature; and even ask, “Where is my car?”Woo-hoo, pretty exciting right? Not in most cases, actually, but the announcement got me thinking about the limits and perils of voice commands in automotive applications.To read this article in full, please click here

Mininet, ONOS, and segment routing

Leaf and spine traffic engineering using segment routing and SDN and CORD: Open-source spine-leaf Fabric describe a demonstration at the 2015 Open Networking Summit using the ONOS SDN controller and a physical network of 8 switches.

This article will describe how to emulate a leaf and spine network using Mininet and configure the ONOS segment routing application to provide equal cost multi-path (ECMP) routing of flows across the fabric. The Mininet Dashboard application running on the sFlow-RT real-time analytics platform is used to provide visibility into traffic flows across the emulated network.

First, run ONOS using Docker:
docker run --name onos --rm -p 6653:6653 -p 8181:8181 -d onosproject/onos
Use the graphical interface, http://onos:8181, to enable the OpenFlow Provider Suite, Network Config Host Provider, Network Config Link Provider, and Segment Routing applications. The screen shot above shows the resulting set of enabled services.

Next, install sFlow-RT and the Mininet Dashboard application on host with Mininet:
wget https://inmon.com/products/sFlow-RT/sflow-rt.tar.gz
tar -xvzf sflow-rt.tar.gz
./sflow-rt/get-app.sh sflow-rt mininet-dashboard
Start sFlow-RT:
./sflow-rt/start.sh
Download the sr.py script:
wget https://raw.githubusercontent.com/sflow-rt/onos-sr/master/sr.py
Start Mininet:
sudo env ONOS=10.0.0.73 mn --custom sr.py,sflow-rt/extras/sflow.py \

Download Malwarebytes Today and Protect Your Data for Free

Everyone lives on the internet, period. Whether you’re streaming a standup special on Netflix, answering emails from your boss, chatting on Tinder, or completing everyday errands like paying bills online, you’re likely spending most of your day tangled up in the world wide web. Unfortunately, that makes you a high-risk candidate for a cyber attack at some point along the way, be it through malware, phishing, or hacking. Best-case scenario, it sucks up your time to fix (or your money by paying someone else to fix it). Worst case scenario, it puts you and your computer out of commission for days and damages your files beyond repair. Not to mention the sheer terror of knowing some hacker has complete and total access to virtually everything about you, including all of your banking and credit card information. Malwarebytes is a free program built to help you avoid the above scenarios altogether — and it makes traditional antivirus look old, tired, and played out (seriously it’s free, download it here).To read this article in full, please click here

In Azacualpa, Honduras: “Smart Communities” Help Preserve Collective Memory

Access to the Internet can change people’s lives for the better. This is particularly true when communities take ownership of that access and take full advantage of it to improve their quality of life. This has been the case in the community of Azacualpa, a village in Intibucá in Honduras.

In Azacualpa, the members of the community took on the task of developing and implementing the project “Smart Communities” in order to reduce the digital divide – and preserve their collective memory. The project, which is part of the Internet Society’s Beyond the Net program, finds its origin in “Radio Azacualpa – The Voice of Women,” a community radio station that started in 2017.

By 2018, Smart Communities expanded its reach by impacting the nearly 400 families that inhabit the Azacualpa Valley. To achieve its objectives, the team divided the tasks into three main groups: administrative aspects, project governance, and technical aspects. The three working groups were accompanied by the Honduras Chapter of the Internet Society and the organization Sustainable Development Network Honduras (RDS-HN).

The participation of the community was fundamental. In addition to promoting a consultation with the community, the project facilitators promoted training in communications so that community Continue reading

RHEL 8 Beta arrives with application streams and more

The leading enterprise Linux platform is now available in a new and highly innovative Beta release. Among other highlights that promise a transformation of business IT well into the future, Red Hat Enterprise Linux 8 Beta: Introduces application streams separating user space packages from core kernel operations and making it easier to update user packages without requiring major version updates of the OS itself. Provides security updates with both OpenSSL 1.1.1 and TLS 1.3 supported. Includes Composer to make it easier for both new and experienced Red Hat Enterprise Linux users to build and deploy custom images across the hybrid cloud. Adds Stratis — a new volume-management file system that is faster, more efficient and easier to manage than its predecessors. Much of the impetus for RHEL 8 has been the growing need for a common foundation that can span every IT stronghold from the data center to multiple public clouds and make application delivery a lot more manageable. Four years have passed since RHEL 7 came our way, and so much has changed in the world of IT since then, with continued virtualization and containerization along with a growing need for rapid deployment.To read Continue reading
