Introducing Cursor: the Cloudflare AI Assistant

Today we’re excited to be launching Cursor – our experimental AI assistant trained to answer questions about Cloudflare’s Developer Platform. This is just the first step in our journey to help developers build in the fastest way possible using AI, so we wanted to take the opportunity to share our vision for a generative developer experience.

Whenever a new, disruptive technology comes along, it’s not instantly clear what the native way to interact with that technology will be.

However, if you’ve played around with Large Language Models (LLMs) such as ChatGPT, it’s easy to get the feeling that this is something that’s going to change the way we work. The question is: how? While this technology already feels super powerful, today, we’re still in the relatively early days of it.

While Developer Week is all about meeting developers where they are, this is one of the things that’s going to change just that — where developers are, and how they build code. We’re already seeing the beginnings of how the way developers write code is changing, and adapting to them. We wanted to share with you how we’re thinking about it, what’s on the horizon, and some of the large Continue reading

Introducing Constellation, bringing AI to the Cloudflare stack

This post is also available in 简体中文, 日本語, Deutsch and Español.

The Cloudflare Workers' ecosystem now features products and features ranging from compute, hosting, storage, databases, streaming, networking, security, and much more. Over time, we've been trying to inspire others to switch from traditional software architectures, proving and documenting how it's possible to build complex applications that scale globally on top of our stack.

Today, we're excited to welcome Constellation to the Cloudflare stack, enabling developers to run pre-trained machine learning models and inference tasks on Cloudflare's network.

One more building block in our Supercloud

Machine learning and AI have been hot topics lately, but the reality is that we have been using these technologies in our daily lives for years now, even if we do not realize it. Our mobile phones, computers, cars, and home assistants, to name a few examples, all have AI. It's everywhere.

But it isn't a commodity to developers yet, though. They often need to understand the mathematics behind it, the software and tools are dispersed and complex, and the hardware or cloud services to run the frameworks and data are expensive.

Today we're introducing another feature to our stack, allowing everyone to Continue reading

Query Cloudflare Radar and our docs using ChatGPT plugins

When OpenAI launched ChatGPT plugins in alpha we knew that it opened the door for new possibilities for both Cloudflare users and developers building on Cloudflare. After the launch, our team quickly went to work seeing what we could build, and today we’re very excited to share with you two new Cloudflare ChatGPT plugins – the Cloudflare Radar plugin and the Cloudflare Docs plugin.

The Cloudflare Radar plugin allows you to talk to ChatGPT about real-time Internet patterns powered by Cloudflare Radar.

The Cloudflare Docs plugin allows developers to use ChatGPT to help them write and build Cloudflare applications with the most up-to-date information from our documentation. It also serves as an open source example of how to build a ChatGPT plugin with Cloudflare Workers.

Let’s do a deeper dive into how each of these plugins work and how we built them.

Cloudflare Radar ChatGPT plugin

When ChatGPT introduced plugins, one of their use cases was retrieving real-time data from third-party applications and their APIs and letting users ask relevant questions using natural language.

Cloudflare Radar has lots of data about how people use the Internet, a well-documented public API, an OpenAPI specification, and it’s entirely built on Continue reading

netlab Release 1.5.3: libvirt Public Networks

containerlab release 0.41.0 that came out a few days ago changed a few topology attributes with no backward compatibility, breaking netlab for anyone doing a new installation. The only way out of that conundrum was to push out a new netlab release that uses the new attributes and requires containerlab release 0.41.0 (more about that in a minute).

On a more positive note, netlab release 1.5.3 brings a few interesting features, including:

• Support for public libvirt networks that can be used to connect your labs to the outside world, and reuse of existing libvirt networks
• ‘unknown’ device type that can be used to deploy devices not yet supported by netlab
• MPLS/VPN support on Nokia SR-OS

Batteries included: how AI will transform the who and how of programming

The 1947 paper titled “Preparation of Problems for EDVAC-Type Machines” talks about the idea and usefulness of a “subroutine”. At the time there were only a tiny number of computers worldwide and subroutines were a novel idea, and it was clear that these subroutines were going to make programmers more productive: “Many operations which are thus excluded from the built-in set are still of sufficiently frequent occurrence to make undesirable the repetition of their coding in detail.”

Looking back it seems amazing that subroutines had to be invented, but at the time programmers wrote literally everything they needed to complete a task. That made programming slow, error-prone and restricted who could be a programmer to a relatively small group of people.

Luckily, things changed.

You can look at the history of computer programming as improvements in programmer productivity and widening the scope of who is a programmer. Think of syntax highlighting, high-level languages, IDEs, libraries and frameworks, APIs, Visual Basic, code completion, refactoring tools, spreadsheets, and so on.

And here we are with things changing again.

The new programmers

The recent arrival of LLMs capable of assisting programmers in writing, debugging and modifying code is yet Continue reading

Welcome to Developer Week 2023

This post is also available in French, Spanish, German, Japanese, Chinese.

It is an incredibly exciting time to be a developer.

The frameworks, libraries and developer tools we depend on keep leveling up in ways that allow us to build more efficiently. On top of that, we’re using AI-powered tools like ChatGPT and GitHub Copilot to ship code quicker than many of us ever could have imagined. This all means we’re spending less time on boilerplate code and setup, and more time writing the code that makes our applications unique.

It’s not only a time when we’re equipped with the tools to be successful in new ways, but we're also finding inspiration in what’s happening around us. It feels like every day there’s an advancement with AI that changes the boundaries of what we can build. Across meetups, conferences, chat rooms, and every other place we gather as developers, we’re pushing each other to expand our ideas of what is possible.

With so much excitement permeating through the global developer community, we couldn’t imagine a better time to be kicking off Developer Week here at Cloudflare.

A focus on developer experience

Worth Reading: Official Ansible Collection for SR Linux

Roman Dodin wrote an article describing Nokia’s Ansible collection for SR Linux. Although I don’t use SR Linux (even though it was the first container supported by netlab ;), it was still very interesting to read about the design tradeoffs they had to make:

Service Insertion with BGP FlowSpec

Nicola Modena had an interesting presentation describing how you can use BGP FlowSpec for traffic steering and service insertion during the recent ITNOG 7 event (more about the event in a few days).

One of the slides explained how to use three different aspects of BGP (FlowSpec, MPLS/VPN and multipathing), prompting me to claim the presentation title should be “BGP is the answer, what was the question?” 😉 Hope you’ll enjoy the PDF version of the presentation as much as we did the live one.

ZModem over amateur radio

While I have built a file transfer protocol for AX.25, I also wanted to try old BBS era protocols. They’re more tested and standardized.

The easiest way is probably to take lrzsz and let it talk over AX.25 connected sockets. Ideally socat should be enough, but it seems that it does not support AX.25.

That’s actually fine, because ideally I want to run on my authenticated wrapped AX.25 (while encryption, obscuring the meaning, is banned, signatures are not).

So I had to make an adapter that bridges stdin/stdout to AX.25. Simple enough.

The setup is two Kenwood TH-D74s, set up the same way as before, in 9600bps.

D74 -> rfcomm -> kissattach -> axpipe -> socat -> lrzsz

The D74 is a great radio. It has the best text entry, menu system, and APRS support of any handheld radio I’ve seen, and it also has a built-in TNC (“modem”) that works both in 1200bps and 9600bps.

First, just for fun, let’s try YModem.

YModem

socat EXEC:'sz --ymodem axpipe.cc' EXEC:'./axpipe -r radio1 -l 0'
socat EXEC:'rz --ymodem -t 100'    EXEC:'./axpipe -r radio6 -s M6VMB-12 -c M0THC-1'

Cloudflare’s view of Internet disruptions in Pakistan

On Tuesday, May 9, Imran Khan, former Prime Minister of Pakistan was arrested on corruption charges. Following the arrest, violent protests erupted in several cities, leading the government of Pakistan to order the shutdown of mobile Internet services, as well as the blocking of several social media platforms. Below, we examine the impact of these shutdowns at a national and local level, as seen through Cloudflare traffic data. In addition, we illustrate how Pakistanis appear to be turning to Cloudflare’s 1.1.1.1 resolver in an attempt to maintain access to the open Internet.

General traffic trends

Since Tuesday, May 9, peak traffic levels aggregated at a country level (as measured by HTTP request volume) have been declining, down nearly 30% during the first several days of the mobile Internet shutdowns. The lowest traffic levels (nadirs of the graph) have also declined, dropping by as much as one-third as well. In the sections below, we drill down into this traffic loss, looking at outages at a network level, and the impact of those outages at an administrative unit and city level.

The mobile network shutdowns have also impacted the profile of traffic that Cloudflare sees from Pakistan. In Continue reading

How to integrate Calico Image Scanner with Argo CI/CD

In today’s fast-paced software development environment, developers often use common public libraries and modules to quickly build applications. However, this presents a significant challenge for DevOps teams who must ensure that these applications are safe to use. As organizations move towards dynamic models of software development that rely on Continuous Integration and Continuous Deployment, the responsibility for deploying secure applications has shifted from traditional security teams to development teams.

To address this challenge, I will provide general guidelines on how to integrate the Calico Image Scanning feature into a CI/CD pipeline, using Argo. This will help ensure that images are built safely and free from Common Vulnerabilities and Exposures (CVEs). In this blog post, we will use a Kubernetes validating webhook configuration to attach a Calico Cloud admission controller that can accept or reject certain actions on resources, such as the creation of pods. This will prevent the deployment of images that contain known CVEs, thus strengthening the overall security of your software development process.

Overall Architecture

The building blocks to use Argo as an example of this integration are below:

Relevant Calico configuration

Before even committing changes to our application, we must setup the Calico Admission Controller within our Continue reading
