Hedge 145: Roundtable on Professional Liability
The software world is known for overdue projects, costs overrun, lots of defects, and lots of failure all the way around. Many other engineering fields have stricter requirements to take on projects and liability insurance driving correct practice and care. The networking world, and the larger IT world, however, has neither of these things. Does this make IT folks less likely to “do the right thing,” or is the self-regulation we have today enough? Join Tom Ammon, Eyvonne Sharp, and Russ White as they discuss the possibilities of professional liability in information technology.
Know Your Adversaries: The Top Network Bad Actors
The bad guys are out to steal your data, identity, money, and anything else they can lay their digital hands on. Here's a rundown of today's major adversaries.Collecting and Processing Data from Pokec using Python
Recently I have programmed Python scripts - config.py and pokec_get_stats.py, which I can use to collect statistics about the users in a particular room of the popular Slovak social network Pokec. My goal is to practice the Python programming and test the functionality of Selenium WebDriver. The Selenium WebDriver is used to emulate user interaction […]Continue reading...

Kubernetes Unpacked 008: Go – The Language Of Kubernetes
In this episode, Michael catches up with Josh Duffney, Cloud Developer Advocate at Microsoft to talk about Go (golang). Kubernetes, Docker, and Terraform are all written in Go. Josh and Michael talk about their journey into Kubernetes and Go, some fun projects to play with, how to learn Go, and why understanding certain programming languages is crucial for breaking into Kubernetes.

This is the first video in a new series that explores service mesh and ingress in Kubernetes. This video provides a basic overview of ingress and service mesh, how they work, and the roles they play in a Kubernetes cluster. Michael Levan brings his background in system administration, software development, and DevOps to this video […]

Router Interfaces and Switch Ports
When I started implementing the netlab VLAN module, I encountered (at least) three different ways of configuring physical interfaces and bridging domains even though the underlying packet forwarding operations (and sometimes even the forwarding hardware) are the same. That confusopoly is guaranteed to make your head spin for years, and the only way to figure out what’s going on behind the scenes is to go back to the fundamentals.

VMware Aria: If You Can’t Beat Public Cloud, Maybe You Can Manage It
VMware announced an ambitious project, VMware Aria, at VMware Explore 2022. Aria offers multi-cloud management for enterprises that use services in more than one public cloud. The speed and sprawl of cloud adoption has become a problem for enterprises. Companies are having a hard time containing costs, monitoring performance, and enforcing security and compliance policies. […]

DoH, DoT and plain old DNS
We’d like to understand the extent to which encrypted DNS technologies have been taken up in the public Internet. To this end, we've been able to analyse the query data from a large open recursive resolver system to provide some insights as to how much use is being made of DNS over HTTPS and DNS over TLS.DDoS Sonification
Sonification presents data as sounds instead of visual charts. One of the best known examples of sonification is the representation of radiation level as a click rate in a Geiger counter. This article describes ddos-sonify, an experiment to see if sound can be usefully employed to represent information about Distributed Denial of Service (DDoS) attacks. The DDoS attacks and BGP Flowspec responses testbed was used to create the video demonstration at the top of this page in which a series of simulated DDoS attacks are detected and mitigated. Play the video to hear the results.
The software uses the Tone.js library to control Web Audio sound generation functionality in a web browser.
var voices = {};
var loop;
var loopInterval = '4n';
$('#sonify').click(function() {
if($(this).prop("checked")) {
voices.synth = new Tone.PolySynth(Tone.Synth).toDestination();
voices.metal = new Tone.PolySynth(Tone.MetalSynth).toDestination();
voices.pluck = new Tone.PolySynth(Tone.PluckSynth).toDestination();
voices.membrane = new Tone.PolySynth(Tone.MembraneSynth).toDestination();
voices.am = new Tone.PolySynth(Tone.AMSynth).toDestination();
voices.fm = new Tone.PolySynth(Tone.FMSynth).toDestination();
voices.duo = new Tone.PolySynth(Tone.DuoSynth).toDestination();
Tone.Transport.bpm.value=80;
loop = new Tone.Loop((now) => {
sonify(now);
},loopInterval).start(0);
