5G: mm-wave signals could power self-charging IoT devices

A 3D-printed antenna could turn high-frequency 5G signals into a wireless power source, potentially eliminating the need for batteries in low-power IoT devices, according to researchers at Georgia Tech. 5G resources What is 5G? Fast wireless technology for enterprises and phones How 5G frequency affects range and speed Private 5G can solve some problems that Wi-Fi can’t Private 5G keeps Whirlpool driverless vehicles rolling 5G can make for cost-effective private backhaul CBRS can bring private 5G to enterprises The antenna, which the researchers call a mm-wave harvester, is about the size of a playing card and has visible circuitry printed on it. It uses a technology called a Rotman lens as a waveguide to focus multiple beams of millimeter-wave electromagnetic radiation used in 5G into a coherent whole.To read this article in full, please click here

Researchers show that quantum computers can reason

Quantum computers can learn to reason, even when burdened with uncertainty and incomplete data, concludes a team of scientists from U.K.-based quantum software developer Cambridge Quantum Computing (CQC).This ability is similar to intuitive human reasoning, which allows people to draw conclusions and make decisions despite a lack of comprehensive information. CQC’s research confirms a belief among many scientists that quantum computers have a natural propensity for reasoning.[Get regularly scheduled insights by signing up for Network World newsletters.] In a paper published on the open-access scholarly archive arXiv, CQC scientists detail how they developed methods that demonstrated how quantum machines can learn to infer hidden information from general probabilistic reasoning models. If replicable, these methods could improve a broad range of applications for quantum computing, including medical diagnoses, fault-detection in mission-critical machines, and financial forecasting for investment management.To read this article in full, please click here

Planning the Extended Coffee Break: Three Months Later

It’s almost exactly three months since I announced ipSpace.net going on an extended coffee break. We had some ideas of what we plan to do at that time, but there were still many gray areas, and thanks to tons of discussions I had with many of my friends, subscribers, and readers, they mostly crystallized into this:

You’re trusting me to deliver. We added a “you might want to read this first” warning to the checkout process, and there was no noticeable drop in revenue. Thanks a million for your vote of confidence!

TeamTNT: Latest TTPs targeting Kubernetes

In April 2020, MalwareHunterTeam found a number of suspicious files in an open directory and posted about them in a series of tweets. Trend Micro later confirmed that these files were part of the first cryptojacking malware by TeamTNT, a cybercrime group that specializes in attacking the cloud—typically using a malicious Docker image—and has proven itself to be both resourceful and creative.

Since this first attack, TeamTNT has continuously evolved its tactics and added capabilities to expand and capture more available cloud attack surfaces. They started with targeting exposed Docker instances and quickly added support for different C2 mechanisms, encryption, DDoS, evasion, persistence and more. Now, their latest variant is targeting the most popular container orchestrator, Kubernetes. Let’s take a closer look.

Evolving Tactics, Techniques and Procedures (TTPs)

TeamTNT’s initial attack targeted an exposed, unprotected Docker API on the internet in order to run an Alpine Linux container. Once the container started running on the unprotected Docker API, a series of scripts were downloaded to facilitate the installation of a Monero cryptominer (to carry out scanning and cleaning activities). A notable script used in the attack was <clean.sh>, which removed a bit of technically advanced Kinsing malware. Kinsing is Continue reading

Requiem for FCoE

FCoE is dead. We’re beyond the point of even asking if FCoE is dead, we all know it just is. It was never widely adopted and it’s likely never going to be widely adopted. It enjoy a few awkward deployments here and there, and a few isolated islands in the overall data center market, but it it never caught on the way it was intended to.

So What Killed FCoE?

So what killed FCoE? Here I’m going to share a few thoughts on why FCoE is dead, and really never was A Thing(tm).

It Was Never Cheaper

Ethernet is the champion of connectivity. It’s as ubiquitous as water in an ocean and air in the.. well, air. All the other mediums (ATM, Frame Relay, FDDI, Token Ring) have long ago fallen by the wayside. Even mighty Infiniband has fallen. Only Fibre Channel still stands as the alternative for a very narrow use case.

The thought is that the sheer volume of Ethernet ports would make them cheaper (and that still might happen), but right now there is no real price benefit from using FCoE versus FC.

In the beginning, especially, FCoE was quite a bit more expensive than running separate Continue reading

Solo.io: Istio Is Winning the Service Mesh War

The open source Istio has emerged as the “dominant” service mesh to manage microservices and Kubernetes environments, solo.io executives say. Gloo Edge 2.0, to be released in beta in the middle of the year is the “first and the only” Istio-native API gateway with all of Istio’s native functionality, Posta said. The ingress controller will integrate #SoloCon2021 https://t.co/VKAxWqk5KJ is fully committed to Istio.

Sarantaporo.gr Community Network: Tending to Our Communities’ Needs with Care and Flexibility

At the beginning of May 2020, the Sarantaporo.gr community network team was approached by the Mayor of Elassona, a municipality in the Thessaly region in central Greece. He was asking for help with a very common problem that villages in our municipality face: lack of access to Internet connectivity. “Sykea” or “Sykia” is an isolated […]

Free Networking ArubaOS-CX Lab Image From Aruba Networks

This is a continuation of my post documenting hassle-free, virtualized network operating system images you can download for labbing and learning.

Aruba Networks (HPE) ArubaOS-CX

What is it?

While you probably think of wireless networking first when Aruba Networks comes up, ArubaOS-CX is a ground-up network operating system for switches built by the former HPE ProCurve team, if memory serves me correctly. Aruba has been a part of HPE for some time, and the networking folks within HPE fall under the Aruba hierarchy as I understand it.

I wrote an overview of ArubaOS-CX as part of a series on the Aruba 8400 switch launch back in October 2017.

Aruba offers a virtual version of ArubaOS-CX delivered as an OVA. You can use the OVA as-is, or extract the OVA tarball to get to the vmdk and convert the vmdk to a qcow2 image, all depending on what your hypervisor needs.

How do I obtain the image?

  1. Create an Aruba Support Portal account & log in via https://asp.arubanetworks.com/.
  2. Head to Software and Documents, currently https://asp.arubanetworks.com/downloads.
  3. In the left pane, filter on…
    1. File type: Software
    2. Product: Aruba Switches
    3. File Category: OVA

Tom’s Corner and Turning Another Corner

Thanks to everyone that popped in for Tom’s Virtual Corner at Cisco Live Global 2021. It was a great time filled with chats about nothing in particular, crazy stories about unimportant things, and even the occasional funny picture. It was just was Tom’s Corner has always been. A way for the community to come together and be around each other in a relaxing and low-key environment. Maybe we couldn’t meet in person but we got together when we needed it the most.

There was also something else that Tom’s Corner has represented for me for the last year that I didn’t even catch until it was pointed out to me by my wonderful wife Kristin (@MrsNetwrkingNerd). Tom’s Corner was the start of something that made me feel better about everything.

Get On Up and Move

After Tom’s Virtual Corner in 2020, I was energized. I needed to get up and get things done after sitting in a chair for hours talking to all my absent friends and getting the energy I needed to feel after months of being locked away during a pandemic. I felt on top of the world for the first time in quite a while. Continue reading

Durable Objects, now in Open Beta

Durable Objects, now in Open Beta
Durable Objects, now in Open Beta

Back in September, we announced Durable Objects - a new paradigm for stateful serverless.

Since then, we’ve seen incredible demand and countless unlocked opportunities on our platform. We’ve watched large enterprises build applications from complex API features to real-time games in a matter of days from inception to launch. We’ve heard from developers that Durable Objects lets them spend time they used to waste configuring and deploying databases on building features for their apps. More than anything, we’ve heard that you want to start building with Durable Objects now.
