$lookup isn't easy to map to Kotlin, but I think that's pretty good?
![// {
// $lookup: {
// from: "comments",
// localField: "_id",
// foreignField: "movie_id",
// let: { movie_year: "$year" },
// pipeline: [
// { $match: { $expr: { $gt: [ { $year: "$date" }, "$$movie_year" ] } } },
// ],
// as: "post_release_comments"
// }
// },
.lookup {
into(Movie::post_release_comments)
val movieYear = let(Movie::year)
from(
allComments
.matchExpr { Comment::year gt movieYear }
)
on(Movie::_id, Comment::movieId)

Isekai as a genre is exploding in popularity because it appeals to a universal desire to get hit by a truck rather than live in the 21st century.
In the last 12 months, 22% of publications in MavenCentral were in groups that use KMP, for a total of 93% of published artifacts
What radicalized you? I remember the 2003 heatwave. I was a child (I know) but I vividly remember the asphalt boiling. At the time, the temperature reached 35°C (95°F). More than 15 000 people died in France, for a total of 72 000 deaths in Europe.
In light blue: Bordeaux Quite a lot of smoke. Right now it's 4am, neighboring cities are being evacuated
The goal of a DSL is to make incorrect code harder to write, and correct code easier to read If your DSL needs to be called in a specific order to work and otherwise silently fails, it's not a very good DSL

I'm not sure *why*, but apparently my test suite crashes MongoDB
Is there any language that generates stacktraces not by snapshotting the current call stack but by building it while unwinding? As in, have a code path on every function for "I'm propagating an error" that appends the current location to a linked list of "where you're coming from".
Congratulations to all my US friends on making it to the end of your epic 250 year experiment with democracy! May the subsequent imperial phase be mercifully brief and the aftermath painless.
I’ve been enjoying these neat API design tricks from @ivcanet.bsky.social. Just handy little patterns to keep in your back pocket when building your own Kotlin libraries: - Non-exhaustive enums: ivan.canet.dev/blog/2026/06... - Mandatory varargs: ivan.canet.dev/blog/2026/03...
Did you know it's possible to create non-exhaustive enums in Kotlin? ivan.canet.dev/blog/2026/06...

yay the weather is liveable again now let's all forget about it so we definitely don't stop the next one :)
btw you probably shouldn't buy a Pixel Watch. They can't pair at the moment, it's been at least a few weeks. Confirmed with Support that it's a known bug. Official recommendation is to wait for a fix. No timeline. Without pairing, they can't even show the time.
the hardest part about creating a simple solution is convincing people the problem it solves was hard in the first place
I've made a Kubernetes that runs in the browser, and today we're open sourcing it. The hope here is to make super interactive and visual web content about Kubernetes much easier to write, and we have a whole bunch planned this year. Repo: github.com/ngrok/webern... Demo: webernetes-demo.ngrok.app
Gradle generates useless checksum files, which leads to a ×2 total number of published files With the recent MavenCentral limits, it's even more important to get this fixed Vote → github.com/gradle/gradl...
stop publishing .asc.${checksums} to Central repository · Issue #20232 · gradle/gradle
Expected Behavior .asc files are published to Maven Central without .asc.${checksum} Current Behavior for example: https://repo1.maven.org/maven2/org/junit/jupiter/junit-jupiter/5.8.2/ junit-jupite...

A single release of SqlDelight publishes 8370 files (the new limits are 1000 files) due to a compounding of Maven Central's requirements to publish javadoc and sources, signatures and checksums of everything, and the fact that the project is well modularized and uses Kotlin multiplatform.
Zac Sweers@zacsweers.dev · 2mo agoSuper sympathetic to Sonatype's situation, hosting isn't free. But announcing this with paltry limits and no public pricing options (a sales contact ain't it) is bad for everyone and going to be a major disruption to the JVM and Kotlin ecosystems. central.sonatype.org/publish/mave...
