Heavy Wireless 008: 3D Printing For Wireless Engineers
3D printing is a popular activity among wireless network engineers. Given that they deal with invisible, intangible radio waves all day, maybe it's no surprise they'd enjoy making things they can touch and feel. On today's Heavy Wireless we talk about why the wireless community enjoys 3D printing, and how engineers can make and use printed objects on the job--and at home.

A Look At Broadcom’s Jericho3-AI Ethernet Fabric: Schedules, Credits, And Cells
Broadcom has come up with some interesting mechanisms to address the challenges of building an Ethernet-based fabric that supports AI workloads. These mechanisms, which include a scheduling framework, cells, and credits, are intended to minimize congestion, latency, and dropped frames or packets in the fabric. In this post I talk about what I learned at […]

Project Cybersafe Schools: Bringing security tools for free to small K-12 school districts in the US
Like other under-resourced organizations, schools face cyber attacks from malicious actors that can impact their ability to safely perform their basic function: teach children. Schools face email, phishing, and ransomware attacks that slow access and threaten leaks of confidential student data. And these attacks have real effects. In a report issued at the end of 2022, the U.S. Government Accountability Office concluded that schools serving kindergarten through 12th grade (K-12) reported significant educational impact and monetary loss due to cybersecurity incidents, such as ransomware attacks. Recovery time can extend from 2 all the way up to 9 months — that’s almost an entire school year.
Cloudflare’s mission is to help build a better Internet, and we have always believed in helping protect those who might otherwise not have the resources to protect themselves from cyberattack.
It is against this backdrop that we’re very excited to introduce an initiative aimed at small K-12 public school districts: Project Cybersafe Schools. Announced as part of the Back to School Safely: K-12 Cybersecurity Summit at the White House on August 8, 2023, Project Cybersafe Schools will support eligible K-12 public school districts with a package of Zero Trust cybersecurity solutions — for Continue reading
Python – Using the IP Address Module to Calculate IPs
I’m currently preparing for a network rollout and the preparation includes assigning subnets to the sites. There are subnets needed for management, wired users, wireless users, guests, and so on. Once subnets have been assigned, for some of the subnets, DHCP scopes need to be created. The team managing the server has requested that information on the subnets, gateway, and what IP the scope begins and ends with be provided as a CSV file. This will allow for easily importing the scopes into the server.
For my scenario, I have the information in a spreadsheet and I’m accessing the information using the openpyxl project. I am then using the ipaddress library to take the prefix from the spreadsheet and performing various calculations. Why use Python for this?
- Writing CSV is time consuming for humans.
- Although I’m quite good at performing calculations, I’m not better than a computer.
- Using code means consistent output that is less error prone.
The goal is to create a line of CSV that looks like this:
VLAN 100 User,192.0.2.64,255.255.255.192,192.0.2.65,192.0.2.75,192.0.2.126,US0100 NY,example.com,
This line consists of:
- Subnet name.
- Network.
- Network mask.
- Gateway.

Enhancing Software Supply Chain Security
Content can be pretty harmful if you cannot trust the source. Much like surfing the internet, we have become accustomed to knowing that if there is a “padlock” in the browser bar then we can consider the site safe. We also know that if we take content from the community, we do so at our own risk, but when you pay for a subscription that offers Red Hat Ansible Certified Content, you expect it to be safe. To drive this manner of safety and instill Continue reading
