How bacteria could run the Internet of Things

Biologically created computing devices could one day be as commonplace as today’s microprocessors and microchips, some scientists believe. Consider DNA, the carrier of genetic information and the principal component of chromosomes; it's showing promise as a data storage medium.A recent study (PDF) suggests taking matters further and using microbes to network and communicate at nanoscale. The potential is highly attractive for the Internet of Things (IoT), where concealability and unobtrusiveness may be needed for the technology to become completely ubiquitous.To read this article in full, please click here

Downgrade all Debian packages to a specific date

Unlike NixOS, Debian doesn’t have a builtin mechanism to rollback an installation to a specific point in time. However, thanks to snapshot.debian.org, a wayback machine for Debian packages, it is possible to downgrade all packages to the versions from a chosen date.

Let’s suppose we want to go back to January, 20^th 2020. In /etc/apt/sources.list.d/snapshot.list, we add a date-specific snapshot as a source:

deb [check-valid-until=no] https://snapshot.debian.org/archive/debian/20200120T111800Z/ unstable main contrib non-free

In /etc/apt/preferences.d/snapshot.pref, we set the priority of all packages from this source to 1001. This is above the default priority of 500 and over 1000 to allow downgrade. See apt_preferences(5) manual page for more details.

Package: *
Pin: origin snapshot.debian.org
Pin-Priority: 1001

After running apt update, we can check the result with apt policy:

$ apt policy
Package files:
 100 /var/lib/dpkg/status
     release a=now
1001 https://snapshot.debian.org/archive/debian/20200120T111800Z unstable/non-free amd64 Packages
     release o=Debian,a=unstable,n=sid,l=Debian,c=non-free,b=amd64
     origin snapshot.debian.org
1001 https://snapshot.debian.org/archive/debian/20200120T111800Z unstable/contrib amd64 Packages
     release o=Debian,a=unstable,n=sid,l=Debian,c=contrib,b=amd64
     origin snapshot.debian.org

     release o=Debian,a=unstable,n=sid,l=Debian,c=main,b=amd64

Apstra’s Intent-Based Networking Brings Enterprises to Cloud Parity

For some companies, things like cloud native deployments on Kubernetes with microservices is a given. For others, those technologies comprise a still distant future, and contemporary complexities include the stuff of network switches, proprietary, vendor-specific configurations, and on-prem networks that require manual operations to manage. For companies in the latter category, intent-based networking (IBN), which means to replace the manual processes of configuring networks and reacting to network issues with a system that responds to a system administrator’s outcome-focused requests. Apstra has been in the business of delivering intent-based networking since 2014, emerging from stealth in 2016. Apstra CEO and co-founder SONiC network operating system, which is based on Linux and is meant to run on switches from various vendors. Much like Apstra’s initial intention of providing a singular, automated entry point to manage a variety of different network components, SONiC provides “a full-suite of network functionality, like BGP and RDMA” that functions regardless of proprietary hardware.

Microsoft Cloud Momentum Sends Q2 Earnings Soaring

You’re Responsible for Resiliency of Your Public Cloud Deployment

Enterprise environments usually implement “mission-critical” applications by pushing high-availability requirements down the stack until they hit networking… and then blame the networking team when the whole house of cards collapses.

Most public cloud providers are not willing to play the same stupid blame-shifting game - they live or die by their reputation, and maintaining a stable service is their highest priority. They will do their best to implement a robust and resilient infrastructure, but will not do anything that could impact its stability or scalability… including the snake oil the virtualization and networking vendors love to sell to their gullible customers. When you deploy your application workloads into a public cloud, you become responsible for the resiliency of your own application, and there’s no magic button that could allow you to push the problems down the stack.

BrandPost: Choose Your Optics: Security Through the SD-WAN Lens in a Hybrid IT World

When we gaze at the crowded eye-chart of technologies commonly associated with digital transformation, few of the markets we follow have been frothier over the last two years than SD-WAN and cybersecurity.The rate of change is remarkable by any long-range indicator: revenue growth rates, investment, acquisition and consolidation activity, and innovation speed. Clearly the essential elements of an extended software-defined network deployment and its critical security posture are inexorably intertwined in the future fabric of a cloud-native, Hybrid IT application delivery world.To read this article in full, please click here
