Mastodon – Part 1 – Installing
About this series
I have seen companies achieve great successes in the space of consumer internet and entertainment industry. I’ve been feeling less enthusiastic about the stronghold that these corporations have over my digital presence. I am the first to admit that using “free” services is convenient, but these companies are sometimes taking away my autonomy and exerting control over society. To each their own of course, but for me it’s time to take back a little bit of responsibility for my online social presence, away from centrally hosted services and to privately operated ones.
This series details my findings starting a micro blogging website, which uses a new set of super interesting open interconnect protocols to share media (text, pictures, videos, etc) between producers and their followers, using an open source project called Mastodon.
Introduction
Similar to how blogging is the act of publishing updates to a website, microblogging is the act of publishing small updates to a stream of updates on your profile. You can publish text posts and optionally attach media such as pictures, audio, video, or polls. Mastodon lets you follow friends and discover new ones. It doesn’t do this in a centralized way, however.

Worth Reading: Resolverless DNS
Geoff Huston published a lengthy article (as always) describing talks from recent OARC meeting, including resolver-less DNS and DNSSEC deployment risks.
Definitely worth reading if you’re at least vaguely interested in the technology that supposedly causes all network-related outages (unless it’s BGP, of course)

Worth Reading: Another Hugo-Based Blog
Bruno Wollmann migrated his blog post to Hugo/GitHub/CloudFlare (the exact toolchain I’m using for one of my personal web sites) and described his choices and improved user- and author experience.
As I keep telling you, always make sure you own your content. There’s absolutely no reason to publish stuff you spent hours researching and creating on legacy platforms like WordPress, third-party walled gardens like LinkedIn, or “free services” obsessed with gathering visitors’ personal data like Medium.

Troubleshooting EVPN with Arista EOS (Control Plane Edition)
“It’s all fun and games until you can’t ping your default gateway.”
While EVPN/VXLAN brings a number of benefits when compared to a more traditional Core/Aggregation/Access layer style network with only VLANs and SVIs, it is different enough that you’ll need to learn some new troubleshooting techniques. It’s not all that different than what you’ve probably done before, but it is different enough to warrant a blog post.
This article is on how to troubleshoot EVPN/VXLAN on Arista EOS switches, and the command line commands will reflect that. However, as EVPN/VXLAN are a collection of IETF standards, the overall technique will translate to any EVPN/VXLAN platform.
The scenario this article is going to explore is endpoint to endpoint connectivity, though it can also be easily modified for endpoint to network connectivity. It doesn’t matter if the host is on the same VXLAN segment or a different one.
The primary strategy will be to verify the control plane. EVPN/VXLAN has a control plane, a data plane, an overlay and an underlay. Generally, I’ve found that most issues occur on the control plane. The control plane process looks like this:
- MAC address is learned on the ingress leaf VLAN
- MAC learning Continue reading
ICYMI: Developer Week 2022 announcements

Heavy Networking 656: Embedding Zero Trust Into Applications
On today's Heavy Networking we look at the idea of embedding zero trust into applications. The way we do cyber security these days has failed in significant ways. What if we could extend the AAA or RBAC model to all applications? Better yet, what if we take the RBAC model, make authentication more robust than username & password, assess endpoint security posture constantly, and evaluate each request individually up at layer 7 for all applications? Guest Galeal Zino has opinions on what embedded zero trust looks like. We discuss.Heavy Networking 656: Embedding Zero Trust Into Applications

How to Launch a Green Computing Initiative That Really Makes a Difference
A growing number of IT organizations are deploying green computing initiatives. Here's how to ensure sure that your project will actually meet its goals.Send Cloudflare Workers logs to a destination of your choice with Workers Trace Events Logpush
When writing code, you can only move as fast as you can debug.
Our goal at Cloudflare is to give our developers the tools to deploy applications faster than ever before. This means giving you tools to do everything from initializing your Workers project to having visibility into your application successfully serving production traffic.
Last year we introduced wrangler tail, letting you access a live stream of Workers logs to help pinpoint errors to debug your applications. Workers Trace Events Logpush (or just Workers Logpush for short) extends this functionality – you can use it to send Workers logs to an object storage destination or analytics platform of your choice.
Workers Logpush is now available to everyone on the Workers Paid plan! Read on to learn how to get started and about pricing information.
Move fast and don’t break things
With the rise of platforms like Cloudflare Workers over containers and VMs, it now takes just minutes to deploy applications. But, when building an application, any tech stack that you choose comes with its own set of trade-offs.
As a developer, choosing Workers means you don't need to worry about any of the underlying architecture. You just write code, Continue reading
Twilio Segment Edge SDK powered by Cloudflare Workers
The Cloudflare team was so excited to hear how Twilio Segment solved problems they encountered with tracking first-party data and personalization using Cloudflare Workers. We are happy to have guest bloggers Pooya Jaferian and Tasha Alfano from Twilio Segment to share their story.
Introduction
Twilio Segment is a customer data platform that collects, transforms, and activates first-party customer data. Segment helps developers collect user interactions within an application, form a unified customer record, and sync it to hundreds of different marketing, product, analytics, and data warehouse integrations.
There are two “unsolved” problem with app instrumentation today:
Problem #1: Many important events that you want to track happen on the “wild-west” of the client, but collecting those events via the client can lead to low data quality, as events are dropped due to user configurations, browser limitations, and network connectivity issues.
Problem #2: Applications need access to real-time (<50ms) user state to personalize the application experience based on advanced computations and segmentation logic that must be executed on the cloud.
The Segment Edge SDK – built on Cloudflare Workers – solves for both. With Segment Edge SDK, developers can collect high-quality first-party data. Developers can also use Segment Edge SDK to Continue reading
Network performance update: Developer Week 2022
Cloudflare is building the fastest network in the world. But we don’t want you to just take our word for it. To demonstrate it, we are continuously testing ourselves versus everyone else to make sure we’re the fastest. Since it’s Developer Week, we wanted to provide an update on how our Workers products perform against the competition, as well as our overall network performance.
Earlier this year, we compared ourselves to Fastly’s Compute@Edge and overall we were faster. This time, not only did we repeat the tests, but we also added AWS Lambda@Edge to help show how we stack up against more and more competitors. The summary: we offer the fastest developer platform on the market. Let’s talk about how we build our network to help make you faster, and then we’ll get into how that translates to our developer platform.
Latest update on network performance
We have two updates on data: a general network performance update, and then data on how Workers compares with Compute@Edge and Lambda@Edge.
To quantify global network performance, we have to get enough data from around the world, across all manner of different networks, comparing ourselves with other providers. We used Real User Measurements (RUM) Continue reading
