Building the program for any conference is not an easy task. There will always be a speaker disappointed that their talk didn’t get in—or perhaps an audience who are disappointed that a particular talk did get in. As the chair of the program committee for Current 22 one of the things that I’ve found really useful in building out the program this time round are the comments that the program committee left against submissions as they reviewed them.

There were some common patterns I saw, and I thought it would be useful to share these here. Perhaps you’re an aspiring conference speaker looking to understand what mistakes to avoid. Maybe you’re an existing speaker whose abstracts don’t get accepted as often as you’d like. Or perhaps you’re just curious as to what goes on behind the curtains :)

I’m convinced that a developer advocate can be effective remotely. As a profession, we’ve all spent two years figuring out how to do just that. Some of it worked out great. Some of it, less so.

I made the decision during COVID to stop travelling as part of my role as a developer advocate. In this article, I talk about my experience with different areas of advocacy done remotely.

I recently started writing an abstract for a conference later this year and realised that I’m not even sure if I want to do it. Not the conference—it’s a great one—but just the whole up on stage doing a talk thing. I can’t work out if this is just nerves from the amount of time off the stage, or something more fundamental to deal with.

This blog is written in Asciidoc, built using Hugo, and hosted on GitHub Pages. I recently wanted to share the draft of a post I was writing with someone and ended up exporting a local preview to a PDF - not a great workflow! This blog post shows you how to create an automagic hosted preview of any draft content on Hugo using GitHub Actions.

This is useful for previewing and sharing one’s own content, but also for making good use of GitHub as a collaborative platform - if someone reviews and amends your PR the post gets updated in the preview too.

Kafka Summit London IS BACK! After COVID spoiled everyone’s fun and fundamentally screwed everything up for the past two years, I cannot wait to be back at an in-person conference. At the last Kafka Summit in the beforetimes (San Francisco, 2019) some of us got together for a run (or walk) across the GoldenGate bridge. I can’t promise quite the same views, but I thought it would be fun to do something similar when we meet in London later this month.

This is the software counterpart to my previous article in which I looked at my workstation’s hardware setup. Some of these are unique or best-of-breed, others may have been sherlocked but I stick with them anyway :)

There’s a bunch of improvements in the works for how ksqlDB handles code deployments and migrations. For now though, for deploying queries there’s the option of using headless mode (which is limited to one query file and disables subsequent interactive work on the server from a CLI), manually running commands (yuck), or using the REST endpoint to deploy queries automagically. Here’s an example of doing that.

The FilePulse connector from Florian Hussonnois is a really useful connector for Kafka Connect which enables you to ingest flat files including CSV, JSON, XML, etc into Kafka. You can read more it in its overview here. Other connectors for ingested CSV data include kafka-connect-spooldir (which I wrote about previously), and kafka-connect-fs.

Here I’ll show how to use it to stream CSV data into a topic in Confluent Cloud. You can apply the same config pattern to any other secured Kafka cluster.

Using ksqlDB in Confluent Cloud makes things a whole bunch easier because now you just get to build apps and streaming pipelines, instead of having to run and manage a bunch of infrastructure yourself.

Once you’ve got ksqlDB provisioned on Confluent Cloud you can use the web-based editor to build and run queries. You can also connect to it using the REST API and the ksqlDB CLI tool. Here’s how.
