Hedge 205: OId Engineering Quotes
For this month’s roundtable, Eyvonne, Tom, and I return to Addresses to Engineering Students by Harrington and Waddell. This book, published in 1912, is a “product of its time,” and hence deserves some trigger warnings. But it is also interesting to see how advice given to engineering students over 100 years ago holds up for today. Have engineering challenges, and the engineering life, changed all that much? What kinds of advice stand the test of time, what kinds do not?
Video: netlab IP Address Management (IPAM)
Did you know that netlab includes full-blown IP address management? You can define address pools (or use predefined ones) and get IPv4 and IPv6 prefixes from those pools assigned to links, interfaces, and loopbacks. You can also assign static prefixes to links, use static IP addresses, interface addresses as an offset within the link subnet, or use unnumbered interfaces.
For an overview of netlab IPAM, watch the netlab address management video (part of the Network Automation Tools webinar), for more details read the netlab addressing tutorial.

Life is Life
The initial idea behind this blog was to have a medium to store and share notes on the different technologies I worked on in an searchable manner. I have decided to step back from work and take a year out so this new life tab of the blog will be for all things non-IT related. I still plan to write technology based blogs over this time (got a few automation projects and Azure tips to share), however this is unlikely to start happening until later into next year.
The Benefits of Comprehensive Observability and Potent Analytics for Enterprise Networks
A real-time, dynamic, and high-definition network map can often provide information about whether the network is functioning properly or whether there are problems with any particular device.While you sleep, Automate resolving Dynatrace problem alerts and report them to ServiceNow!
Integrating observability tools with automation is paramount in the realm of modern IT operations, as it fosters a symbiotic relationship between visibility and efficiency. Observability tools provide deep insights into the performance, health, and behavior of complex systems, enabling organizations to proactively identify and rectify issues before they escalate.
When seamlessly integrated with automation frameworks, these tools empower businesses to not only monitor but also respond to dynamic changes in real time. This synergy between observability and automation enables IT teams to swiftly adapt to evolving conditions, minimize downtime, and optimize resource utilization. By automating responses based on observability data, organizations can enhance their agility, reduce manual intervention, and maintain a robust and resilient infrastructure. In essence, using observability with automation is indispensable for achieving a proactive, responsive, and streamlined operational environment in the fast-paced and complex landscape of today’s technology.
In this blog post, we will look at a common use case involving the monitoring of processes on both bare metal and virtual machines. Our exploration will focus on utilizing Dynatrace's OneAgent, a deployed binary file on hosts that encompasses a suite of specialized services meticulously configured for environment monitoring. These services actively gather telemetry metrics, capturing insights into Continue reading
What is an IPU (Infrastructure Processing Unit) and How Does it Work?
IPUs (Infrastructure Processing Units) are hardware accelerators designed to offload compute-intensive infrastructure tasks like packet processing, traffic shaping, and virtual switching from CPUs.ML Ops Platform at Cloudflare
We've been relying on ML and AI for our core services like Web Application Firewall (WAF) since the early days of Cloudflare. Through this journey, we've learned many lessons about running AI deployments at scale, and all the tooling and processes necessary. We recently launched Workers AI to help abstract a lot of that away for inference, giving developers an easy way to leverage powerful models with just a few lines of code. In this post, we’re going to explore some of the lessons we’ve learned on the other side of the ML equation: training.
Cloudflare has extensive experience training models and using them to improve our products. A constantly-evolving ML model drives the WAF attack score that helps protect our customers from malicious payloads. Another evolving model power bot management product to catch and prevent bot attacks on our customers. Our customer support is augmented by data science. We build machine learning to identify threats with our global network. To top it all off, Cloudflare is delivering machine learning at unprecedented scale across our network.
Each of these products, along with many others, has elevated ML models — including experimentation, training, and deployment — to a crucial position within Continue reading
AMS-IX Outage: Layer-2 Strikes Again
On November 22nd, 2023, AMS-IX, one of the largest Internet exchanges in Europe, experienced a significant performance drop lasting more than four hours. While its peak performance is around 10 Tbps, it dropped to about 2.1 Tbps during the outage.
AMS-IX published a very sanitized and diplomatic post-mortem incident summary in which they explained the outage was caused by LACP leakage. That phrase should be a red flag, but let’s dig deeper into the details.
