Video: Introducing Transmission Technologies

After discussing the challenges one encounters even in the simplest networking scenario connecting two computers with a cable we took a short diversion into an interesting complication: what if the two computers are far apart and we can’t pull a cable between them?

Trying to answer that question we entered the wondrous world of transmission technologies. It’s a topic one can spent a whole life exploring and mastering, so we were not able to do more than cover the fundamentals of modulations and multiplexing technologies.

Rating IoT devices to gauge their impact on your network

One difficulty designing IoT implementations is the large number of moving parts. Most IoT setups are built out of components from many different manufacturers – one company’s sensors here, another’s there, someone else handling the networking and someone else again making the backend.To help you get a ballpark sense of what any given implementation will demand from your network, we’ve come up with a basic taxonomy for rating IoT endpoints. It’s got three main axes: delay tolerance, data throughput and processing power. Here is an explainer for each. (Terminology note: We’ll use “IoT setup” or “IoT implementation” to refer to the entirety of the IoT infrastructure being used by a given organization.)To read this article in full, please click here

Quest Levels Up, Announces Foglight Evolve Platform

Data center-specific AI completes tasks twice as fast

Data centers running artificial intelligence (AI) will be significantly more efficient than those operating with hand-edited algorithm schedules, say experts at MIT. The researchers there say they have developed an automated scheduler that speeds cluster jobs by up to 20 or 30 percent, and even faster (2x) in peak periods.The school’s AI job scheduler works on a type of AI called “reinforcement learning” (RL). That’s a trial-and-error-based machine-learning method that modifies scheduling decisions depending on actual workloads in a specific cluster. AI, when done right, could supersede the current state-of-the-art method, which is algorithms. They often must be fine-tuned by humans, introducing inefficiency.To read this article in full, please click here

Celebrating Linux’s 28 years

Linux just turned 28 years old. From its modest beginnings as an interesting project to the OS that now empowers all 500 of the top 500 supercomputers, along with a huge variety of tiny embedded devices, its place in today's computing world is unparalleled.I was still working with SunOS at the time that Linux was announced — a couple years before it evolved into the System V based Solaris. The full ramifications of what it would mean to be "open source" weren't clear at the time. I was in love with Unix, and this clearly related newborn was of some interest, but not enough to draw me away from the servers I was managing and articles I was writing in those days.To read this article in full, please click here

Impostor Syndrome and Loser DNA

Most of you are probably already familiar with impostor syndrome. Wikipedia defines it as:

Despite external evidence of their competence, those experiencing this phenomenon remain convinced that they are frauds, and do not deserve all they have achieved. Individuals with impostorism incorrectly attribute their success to luck, or as a result of deceiving others into thinking they are more intelligent than they perceive themselves to be.

Basically, it’s the feeling that you don’t really know how things work and one day you’ll get caught, your lies will be exposed, and the world will come crashing down.

Let me let you in on a secret, all people has likely felt as an impostor at times. Even the people you look up to the most. Lately, there has been a lot of tweets and blog posts on impostor syndrome, and that is great. Raising awareness is the first step. However, not many people are saying what to do about it or how to prevent you from developing a “loser DNA”. What is loser DNA?

My Friend Nick Russo wrote about it after listening to Gary Vaynerchuck. Loser DNA is when you compare yourself to others that are, at least according to you, a lot more advanced Continue reading

Upcoming Events and Webinars (September 2019)

We’re back from the summer break for real - the first autumn 2019 ipSpace.net event takes place today: I’ll talk about the fallacies of distributed computing.

September will be an intensive month:

• We’re starting the autumn 2019 network automation course on September 3^rd;
• A week after that (September 10^th) I’ll run a day-long VMware NSX workshop in Zurich;
• Azure Networking webinar series is starting on September 12^th and continuing on September 24^th;
• Lukas Krattiger will talk about service insertion in leaf-and-spine fabrics on September 17^th.

Of course, we’ll keep going… our event calendar is fully packed till mid-November. More about that in a month.

VMware touts hyperscale SD-WAN

SAN FRANCISCO –  VMware teamed with Dell/EMC this week to deliver an SD-WAN service that promises to greatly simplify setting up and supporting wide-area-network connectivity.The Dell EMC SD-WAN Solution is a package of VMware software with Dell hardware and software that will be managed by Dell and sold as a package by both companies and their partners.The package, introduced at the VMworld event here, includes VMware SD-WAN by VeloCloud software available as a subscription coupled with appliances available in multiple configurations capable of handling 10Mbps to 10Gbps of traffic, depending on customer need, said Sanjay Uppal, vice president and general manager of VMware’s VeloCloud Business Unit.To read this article in full, please click here
