IoT startup makes battery-free sensors

[Get regularly scheduled insights by signing up for Network World newsletters.] A startup founded by two MIT grads says that it can deploy self-powering sensors to handle low-intensity IoT tasks, eliminating the need for batteries or power cabling and adding a new level of flexibility to IoT deployments.Ben Calhoun and Dave Wentzloff are the founders of Everactive, an IoT-device startup whose sensor modules can create their own power from a variety of sources, including indoor solar that gathers energy from artificial lighting, and thermal-gradient differential using waste heat to generate electricity. These techniques don’t generate a lot of power but don’t need to for Everactive’s purposes.To read this article in full, please click here

Thank You for Everything Irena, We’ll Miss You Badly

In February 2018, Irena Marčetič joined ipSpace.net to fix the (lack of) marketing. After getting that done, she quickly took over most of sales, support, logistics, content production, guest speaker coordination… If you needed anything from us in the last few years, it was probably Irena answering your requests and helping you out.

She did a fantastic job and transformed ipSpace.net from Ivan and an occasional guest speaker to a finely tuned machine producing several hours of new content every month. She organized our courses, worked with guest speakers, podcast guests and hosts, participated in every guest speaker webinar to take notes for the editing process, managed content editing, watched every single video we created before it was published to make sure the audio was of acceptable quality and all the bloopers were removed… while answering crazy emails like I need you to fill in this Excel spreadsheet with your company data because I cannot copy-paste that information from your web site myself and solving whatever challenges our customers faced.

Unfortunately, Irena decided to go back to pure marketing and is leaving ipSpace.net today. Thanks a million for all the great work – we’ll badly miss you.

What is edge computing and why does it matter?

Edge computing is transforming how data generated by billions of IoT and other devices  is stored, processed, analyzed and transported.The early goal of edge computing was to reduce the bandwidth costs associated with moving raw data from where it was created to either an enterprise data center or the cloud. More recently, the rise of real-time applications that require minimal latency, such as autonomous vehicles and multi-camera video analytics, are driving the concept forward.The ongoing global deployment of the 5G wireless standard ties into edge computing because 5G enables faster processing for these cutting-edge, low-latency use cases and applications.To read this article in full, please click here

How Routers Really Work Live Webinar

I’m teaching a webinar on router internals through Pearson (Safari Books Online) on the 23rd of July. From the abstract—

A network device—such as a router, switch, or firewall—is often seen as a single “thing,” an abstract appliance that is purchased, deployed, managed, and removed from service as a single unit. While network devices do connect to other devices, receiving and forwarding packets and participating in a unified control plane, they are not seen as a “system” in themselves.

How to dig up configuration details on your Linux system with getconf

Linux systems can report on a lot more configuration details than you likely ever knew were available. The trick is using the getconf command and having an idea what you are looking for. Watch out though. You might find yourself a bit overwhelmed with how many settings are available.To start, let's look at a few settings that you might have expected to see to answer  some important questions.Summarizing your command-line usage on Linux For starters, how long can a filename be?You can check this setting by looking at the NAME_MAX setting.To read this article in full, please click here

The 10 most powerful companies in enterprise networking 2021

When the pandemic hit last spring, employees suddenly began working from home, enterprises quickly shifted applications to the cloud, and secure remote access became critical. As we move (hopefully) beyond the pandemic, it’s clear that enterprise networking has been changed forever.Companies are looking at new technologies like SASE to combine networking and edge security into one manageable platform. Zero-trust network access has moved from the back burner to the hotseat as companies seek a more effective way to fight cyberattacks in a world where the traditional perimeter no longer exists. The lines between security and networking are blurring, with traditional security companies moving into the networking realm, and networking companies upping their security game.To read this article in full, please click here

Details and Complexity

What is the first thing almost every training course in routing protocols begin with? Building adjacencies. What is considered the “deep stuff” in routing protocols? Knowing packet formats and processes down to the bit level. What is considered the place where the rubber meets the road? How to configure the protocol.

I’m not trying to cast aspersions at widely available training, but I sense we have this all wrong—and this is a sense I’ve had ever since my first book was released in 1999. It’s always hard for me to put my finger on why I consider this way of thinking about network engineering less-than-optimal, or why we approach training this way.

This, however, is one thing I think is going on here—

The typical program aims to counter the inherent complexity of the decision by providing in-depth information. By providing such extremely detailed and complex information, these interventions try to enable people to make perfect decisions.

We believe that by knowing ever-deeper reaches of detail about a protocol, we are not only more educated engineers, but we will be able to make better decisions in the design and troubleshooting spaces.

To some degree, we think we are managing the Continue reading

The Week in Internet News: EU Launches Antitrust Investigation of Google

Competing for ads: The European Union has launched an antitrust investigation of Google’s advertising practices, with investigators looking into whether the company favored its own online advertising technology, CNBC reports. The probe will look into whether made it harder for other online advertising services to compete. Blocking the ads: In a related story, Google has […]

What Makes A Senior IT Engineer “Senior”?

Ravi asks the following…

I’m trying to figure out what makes a network engineer truly a “senior” engineer. What skills, mostly non-technical, do they possess in order to bring value to the work place?

I’ll share my opinions based on my experience having held junior and senior IT engineering roles, as well as multiple managerial stints with engineers as direct reports. I’m mostly going to address IT engineering broadly rather than networking specifically, as my opinion is the same no matter which tech silo an engineer might hail from.

Technical Skills

As Ravi asked about “mostly non-technical” skills, I’ll be brief here. From a technical perspective, I believe a senior IT engineer is primarily differentiated from a junior in one word–experience. The senior engineer has installed more systems, planned more changes, fixed more problems, and survived more outages than a junior engineer in the same organization.

Ideally, that experience has led to wisdom about how technology can best serve the business needs of an organization. This wisdom will tend to eschew needlessly complex designs, nerd knobs, and “science experiments” conducted in production. This wisdom will also result in difficult problems being resolved more quickly. Experienced folks know somewhat instinctively Continue reading
