Rails 6 Forms With Bootstrap 5 Styling
Forms allow you to receive data from your users via the webapp and store that information in your database and/or send it off for external processing to something like an API. In this post I will go over the process of using forms in rails 6 and styling them with the Bootstrap 5 CSS ...JNCIE-DC lab in EVE-NG
As explained in my previous post on my home servers, I have a bare metal system deployed with EVE-NG Pro installed. As I’m (slowly) preparing for the JNCIE-DC certification I wanted to share the topology that I’m using. As the hardware required to study for the JNCIE-DC is quite significant, it makes a lot of […]

It's Christmas time and you've been wracking your brain trying to find the perfect gift that will teach your loved ones about the cloud in a simple and entertaining way. What to do?
Fortunately for you, Santa has a new elf this year—Forrest Brazeal—who is part AWS Serverless Hero, part skilled cartoonist, and part cloud guru.
Yes, it's a cartoon book about the cloud!
No, I didn't think it could be done either, but Forrest pulled it off with a twinkle in his eyes and little round belly that shook when he laughed, like a bowl full of jelly.
One of the many five-star reviews:
The Read Aloud Cloud is a delightful book. It's 165 pages of hand-drawn cartoons, entertaining verse, and hard-won wisdom.
It truly is a load of fun to flip through. I read it to my kids (8 & 6), and they love it. I'll share it with my parents so they can finally understand what I do. I learned a ton about the history of computing and of course all the ways that we as humans stumble through making our computers do what we want.
Chapter Members Pool Ideas to Inspire New Use Case on Content Filtering
Earlier this year, chapter members from around the world were asked to assist a government minister with an important project. The minister had been tasked with giving an emergency briefing on content filtering and needed the chapter members to help assess an important question. Would the critical properties of the Internet Way of Networking – the foundation that makes the Internet work for everyone – be impacted by the minister’s new policy on content filtering?
While some of the Chapter members held experience in Internet policy, others were relative novices. But as they explored the multiple dimensions and implications of different filtering and blocking techniques, they had a new, powerful tool in their arsenal: the Internet Impact Assessment Toolkit.
The government minister was fictitious, part of a mock scenario created by the Internet Society in collaboration with chapter members participating in chapter workshops. It was a powerful demonstration of how the Internet Impact Assessment Toolkit can evaluate the real-world impact of proposed Internet policy.
During the Latin American Chapter Workshop, about 140 people joined the session dedicated to the discussion of content filtering. Once the mock case was presented, participants were invited to explore the various angles of different filtering and Continue reading
Compiling Qt with Docker multi-stage and multi-platform
This is a guest post from Viktor Petersson, CEO of Screenly.io. Screenly is the most popular digital signage product for the Raspberry Pi. Find Viktor on Twitter @vpetersson.
For those not familiar with Qt, it is a cross-platform development framework that is used in a wide range of products, including cars (Tesla), digital signs (Screenly), and airplanes (Lufthansa). Needless to say, Qt is very powerful. One thing you cannot say about the Qt framework, however, is that it is easy to compile — at least for embedded devices. The countless blog posts, forum threads, and Stack Overflow posts on the topic reveal that compiling Qt is a common headache.
As long-term Qt users, we have had our fair share of battles with it at Screenly. We migrated to Qt for our commercial digital signage software a number of years ago, and since then, we have been very happy with both its performance and flexibility. Recently, we decided to migrate our open source digital signage software (Screenly OSE) to Qt as well. Since these projects share no code base, this was a greenfield opportunity that allowed us to start afresh and explore Continue reading
Integrating Cloudflare Gateway and Access
We’re excited to announce that you can now set up your Access policies to require that all user traffic to your application is filtered by Cloudflare Gateway. This ensures that all of the traffic to your self-hosted and SaaS applications is secured and centrally logged. You can also use this integration to build rules that determine which users can connect to certain parts of your SaaS applications, even if the application does not support those rules on its own.
Stop threats from returning to your applications and data
We built Cloudflare Access as an internal project to replace our own VPN. Unlike a traditional private network, Access follows a Zero Trust model. Cloudflare’s edge checks every request to protected resources for identity and other signals like device posture (i.e., information about a user’s machine, like Operating system version, if antivirus is running, etc.).
By deploying Cloudflare Access, our security and IT teams could build granular rules for each application and log every request and event. Cloudflare’s network accelerated how users connected. We launched Access as a product for our customers in 2018 to share those improvements with teams of any size.
Over the last two years, we Continue reading

VMware NSX-T Install Tips & Tricks
Intro It’s a short list of things that you should probably know when installing VMware NSX-T. Of course, installing NSX-T should be done by following the official documentation. This here is just a few additional points that could help. It’s for your peace of mind afterward. This is an article from the VMware from Scratch series NSX Manager is a Cluster of three VMs You should end up having three NSX-Manager VMs in a cluster when you finish NSX-T installation. The first one will be deployed via .ovf file from vCenter, the other two direct from first NSX Manager GUI

What Exactly Happens after a Link Failure?
Imagine the following network running OSPF as the routing protocol. PE1–P1–PE2 is the primary path and PE1–P2–PE2 is the backup path. What happens on PE1 when the PE1–P1 link fails? What happens on PE2?
Sample 4-router network with a primary and a backup path
The second question is much easier to answer, and the answer is totally unambiguous as it only involves OSPF:

New Vulnerability Exposes Kubernetes to Man-in-the-Middle Attacks: Here’s How to Mitigate
What is CVE-2020-8554?
A few weeks ago a solution engineer discovered a critical flaw in Kubernetes architecture and design, and announced that a “security issue was discovered with Kubernetes affecting multi-tenant clusters. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster.” If a hostile user can create a ClusterIP service and set the spec.externalIP field, they can intercept traffic to that IP. In addition, if a user can patch the status of a LoadBalancer service, which is a privileged operation, they can also intercept traffic by exploiting the vulnerability.
Who is Affected?
All Kubernetes versions including the latest release v1.20 are vulnerable to this attack, with the most significant impact being to multi-tenant clusters. Multi-tenant clusters that grant tenants the ability to create and update services and pods are most vulnerable. Since this is a major design flaw with no fix in sight, it becomes imperative to understand and mitigate this CVE.
Technical Overview
The man-in-the-middle (MITM) attack starts with step 1 (shown in the diagram, below). A workload sends a connection request to legitimate IP 4.4. Continue reading
