KotlinConf 2025, May 21–23, Copenhagen KotlinConf is the official Kotlin conference by JetBrains. It is a place for the community to gather and discuss all things Kotlin.

If you missed @kotlinconf.com 2025, you can catch talks on kotlinconf.com, including mine, where I deep-dive into a couple of relatively recent features to learn about Kotlin specifically and find general takeaways for software development and practice.

Jetpack Compose looks simple, but under the surface is a runtime that tracks tree positions, manages groups, and invalidates state precisely.
If you do not understand that system, you cannot use it efficiently.

A Duck Walks into a Lake - MotherDuck Blog DuckDB introduces a new table format, what does it mean for the future of data lakes ? | Reading time: 9 min read

S3 isn’t a database. But what if your lakehouse finally acted like one?

@jrdntgn.bsky.social shares why the current generation of lakehouse formats like Iceberg and Delta Lake might be missing the point—and how DuckLake, a new table format, changes the game.

The Strange Practices at The Broadcaster's Inn • Broadcasting in NumPy (A NumPy for Numpties article) It doesn't take long in the NumPy world before you come across broadcasting.

As there are many new followers in recent days, I'll periodically post the "best of" from The Python Coding Stack…

…today, I'll share this fun (I'd say so, right? You decide) narrative-style article about NumPy broadcasting

Let me know what you think…

The Code That Almost Led to Disaster • A Starbase Story A Python pitfall • Maybe it's not quite Episode IV level of drama, but drama it is nonetheless…

What do you think of Python articles framed within a fiction story, like this one?

www.thepythoncodingstack.com/p/the-code-t...

I have an interest in what I call "narrative technical writing". Story-framing is only one of the techniques I use

I guess it's not for everyone, but what do you think?

I like it. Reminds me of the Head First series of tech books created by Bert Bates and Kathy Sierra back in early 2000's. By immersing the reader in the story, I think it can help some learn topics that they may have previously struggled with.

names = ["Jim", "Audrey", "Clara", "Aaron", "Ishaan", "Amelia"] long_names = [name for name in names if len(name) > 5] print(long_names) # OUTPUT: ['Audrey', 'Ishaan', 'Amelia'] ​

I used trial and error to get the order right for this for so long…until it finally made sense.

In a Python comprehension, why does the `if` sometimes go after the `for` but sometimes before it? [Spoiler alert: it doesn't]

Here's a quick thread. Start with this code…

The `if` is after the `for`…

So many reasons to not use windows

Could not imagine the things that may float by

Happy Anniversary 🥂

How to self-host all of Bluesky except the AppView (for now) — alice.bsky.sh by Alice · 3 min read

If you're interested in running your own PDS (Personal Data Server) so that your posts live on a server that you control, let me know. I'm considering launching a service to automate installation and setup.

To do it yourself, see alice.bsky.sh/post/3laega7..., for example.
