During the last Tech Field Day Extra @ CLEUR, one of the fellow delegates asked me about my opinion on technology X (don’t remember the details, it was probably one of those over-hyped four-letter technologies). As usual, I started explaining the drawbacks, and he quickly stopped me with a totally unexpected question: “Why do you always tend to be so negative?”
That question has been haunting me for months… and here are a few potential answers I came up with.
On Monday we looked at the case for interpretable models, and in Wednesday’s edition of The Morning Paper we looked at CORELS which produces provably optimal rule lists for categorical assessments. Today we’ll be looking at RiskSLIM, which produces risk score models together with a proof of optimality.
A risk score model is a a very simple points-based system designed to be used (and understood by!) humans. Such models are widely used in e.g. medicine and criminal justice. Traditionally they have been built by panels of experts or by combining multiple heuristics . Here’s an example model for the CHADS2 score assessing stroke risk.
Even when you don’t consider interpretability as a goal (which you really should!), “doing the simplest thing which could possibly work” is always a good place to start. The fact that CORELS and RiskSLIM come with an optimality guarantee given the constraints fed to them on model size etc. also means you can make informed decisions about model complexity vs performance trade-offs if a more complex model looks like it may perform better. It’s a refreshing change of mindset to shift from “finding an Continue reading
The Internet of Things promises a transformative impact on a wide range of industries, but along with that promise comes an enormous new level of complexity for the network and those in charge of maintaining it. For the major mobile data carriers in the U.S., that fact suggests an opportunity.The core of the carriers’ appeal for IoT users is simplicity. Opting for Verizon or AT&T instead of in-house connectivity removes a huge amount of the work involved in pulling an IoT implementation together.[Get regularly scheduled insights by signing up for Network World newsletters.]
Operationally, it’s the same story. The carrier is handling the network management and security functionality, and everything involved in the connectivity piece is available through a centralized management console.To read this article in full, please click here
I recently passed the JNCIS Service Provider (JN0-361) certification exam
on my second attempt. This post will cover the materials and methods
I used to tackle this exam.
First Attempt
Juniper had a free cert day on the 17th of September 2019 here in
Australia. From the time it was...
With the growing use of mobile devices and apps, edge computing,and IoT, the network architect role has become more complex and more important to the success of the enterprise.
Today's episode explores how the US federal government views IPv6 adoption. We also explore the use of IPv6 by the U.S. Department of Defense, including innovations, and how the DoD's use affects its work with civilian entities. Our guest is Jeremy Duncan, founder and leading partner of the consultancy Tachyon Dynamics.

The consensus is growing among the big datacenter operators of the world that CPU cores are such a precious commodity that they should never do network, storage, or hypervisor housekeeping work but rather focus on the core computation that they are really acquired to do. …
5 Reasons You Might Be Afraid to Get Started with Kubernetes
Kubernetes has the broadest capabilities of any container orchestrator available today, which adds up to a lot of power and complexity. That can be overwhelming for a lot of people jumping in for the first time – enough to scare people off from getting started. There are a few reasons it can seem intimidating:
It’s complicated, isn’t it? As we noted in a previous post, jumping into the cockpit of a state-of-the-art jet puts a lot of power under you, but how to actually fly the thing is not obvious. If you’ve never done more than play a flight simulator game, it can be downright scary.
Is it production-ready? Everyone is talking about Kubernetes, but it’s only emerged as a major technology in the past few years. Many companies take a wait-and-see approach on new technologies. Building out a Kubernetes deployment on your own means solving challenging problems without enterprise support.
Do I have the people and skills to support it? IT teams are just beginning to learn Kubernetes. If it’s complicated, it means you’ll need people with the right experience to support it. According to industry Continue reading
I installed the Azure CLI in the Termux app on my Android phone. This post describes all the steps required to successfully run Azure CLI on most Android phones.
Installing Azure CLI on Termux on your Android phone is an alternative to using Azure Cloud Shell on Chrome or Firefox, or to using the Cloud Shell feature on the Azure mobile app. It’s also a cool thing to try.
This post is based on the excellent work done by Matthew Emes, who wrote a blog post about installing Azure CLI on a Chromebook. Matthew’s procedure got me started, but I had to modify it to make Azure CLI work in Termux on my Android phone. Also, Azure CLI has changed since Matthew wrote about it and some of his steps, while they still work, are no longer necessary.
Termux
Install Termux on your Android phone. Termux is a terminal emulator and Linux environment that runs on most Android devices with no rooting or setup required. You can use Termux as a terminal emulator to manage remote systems and it will run a large number of Linux utilities and programming languages directly on your phone. Install it from the Google Continue reading
Mad geniuses. Evil dolls. Slow zombies. This Halloween, we’ll see all of these horror film clichés come to life. Sure they’re fun, but are there lessons we can learn from them? What if they could teach us what not to do? We looked at seven scary tropes and what they might teach us about Internet trust.
The call is coming from inside the house.
The phone calls keep coming, each one scarier than the last. Ring. “Are you home alone?” Ring. “Have you locked the doors?” Ring. “Look in the basement.” It’s only then you realize the stalker has been in the house all along.
We lock our doors to make our homes more secure, but we don’t always think about the security of the things we connect to our home networks. An insecure connected device can put your whole network and the devices on it at risk. Meaning, yes, the cybersecurity threat could be coming from inside the house. By protecting your home network, you limit your devices’ exposure to online threats and help mitigate the risk they may pose to others. You can make your network more secure by using encryption, a strong password, and Continue reading
The effective range of Wi-Fi, and other wireless communications used in Internet of Things networks could be increased significantly by adding wireless noise, say scientists.This counter-intuitive solution could extend the range of an off-the-shelf Wi-Fi radio by 73 yards, a group led by Brigham Young University says. Wireless noise, a disturbance in the signal, is usually unwanted.To read this article in full, please click here
Application delivery controller provider Project Nova, a cloud native, hosted ADC service that is managed from a browser.
Nova is a response to customers using their existing ADC device in a manner that was never intended, Snapt CEO request access, with a community edition providing free access for up to five deployed nodes. At launch, Project Nova provides support for native service discovery on Kubernetes, Docker, Rancher, Consul and more, as well as full-automation with a REST API.
Blakey says they expect Project Nova’s beta to be available by mid-November and a full integration with service meshes by mid-December, with ” the real idea to be this app delivery fabric, which just takes responsibility for the delivery of your app across whatever infrastructure you’re running in.” General availability, he says, is expected by early 2020.
